(Universidade Federal de Goiás, 2025-11-25) Radispiel, Júlia Barreto; Bezerra, José Clecildo Barreto; Bezerra, José Clecildo Barreto; Souza, Jéssica Yonara de; Costa, Vinícius Alexandre Fiaia
Human schistosomiasis is a neglected tropical disease transmitted through Biomphalaria glabrata, the intermediate host mollusk of Schistosoma mansoni, affecting millions of people in tropical and subtropical regions. Niclosamide is one of the strategies recommended by the World Health Organization for biological control of snails but it demonstrates high ecotoxicity, motivating the search for new alternatives. Chemoinformatics allows for the understanding and prediction of interactions between molecules and biological targets before experimental synthesis and has been relevant in the prospecting of compounds with molluscicidal potential. Currently there is a gap in the integration between bioassays and prospective results obtained in silico, the consequences of which are the use of larger quantities of compounds and, consequently, higher costs. To evaluate the molluscicidal activity of a naphthoquinone-derived compound on newly hatched B. glabrata snails, obtained from in silico pharmacophoric modeling, snails were exposed in triplicate to concentrations of 3.12 μM, 6.25 μM, 12.5 μM, 25 μM, and 50 μM of the chemical, along with two negative control groups: water and 1% DMSO (DimethylSulfoxide - C2H6OS molecular formula). Snail mortality was monitored daily for 96 hours using a microscope with a camera and LAS EZ software, statistical analysis were performed using the Vegan package of the R Project software. One-tailed analysis of variance (ANOVA) was used to verify the differences in mortality rates of B. glabrata snails exposed to the compound and the controls. LC50 values and their confidence intervals were obtained by regression analysis using the Probit method. The results obtained demonstrated the compound's promising molluscicidal capacity, showing a cumulative effect and a final LC50 of 7.1 μM, demonstrating the viability of conducting further tests with adult snails based on these results. Based on this study, it was possible to establish laboratory parameters for bioassays with molecules prospected in silico using newly hatched snails as an experimental model for laboratory optimization.

Noncommunicable diseases (NCDs) represent a significant challenge to global public health, especially in low- and middle-income countries, where social determinants, socioeconomic inequalities, and barriers to accessing primary care services greatly affect their prevalence and control. This study analyzed lifestyle habits and factors associated with NCD risk in a population from Goiânia, using data obtained from an adapted Vigitel questionnaire. Food consumption, physical activity, smoking, alcohol intake, health perception, and domestic routines were investigated. The results showed a high frequency of risk behaviors, such as regular consumption of ultra-processed foods, low intake of fruits and vegetables, physical inactivity, substantial alcohol consumption, and smoking. These findings highlight the need for educational and intersectoral strategies tailored to local sociocultural realities. As an intervention proposal, a booklet of practical, accessible, and healthy recipes was developed to promote the consumption of fruits and vegetables, translating the identified local needs into educational tools that support healthier food choices and the construction of sustainable food environments, contributing to the prevention of NCDs.

Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition defined by persistent deficits in social interaction and communication, as well as repetitive behaviors and restricted interests. Although the etiology of ASD is multifactorial and heterogeneous, advances in neurobiology point to the involvement of specific neuropeptide pathways associated with the regulation of social behavior, namely the oxytocin (OXT) and arginine vasopressin (AVP) pathways. Thus, this review aims to analyze recent scientific literature on the relationship between the oxytocin and vasopressin systems, their receptors, and social cognition in the context of ASD, in addition to contributing to the understanding of the neurochemical mechanisms involved in the relationship between oxytocin/vasopressin pathways and ASD, compiling information found in articles and genetic databases on the participation of these pathways in ASD, and expanding more targeted therapeutic proposals based on the evidence found. Articles published between 2015 and 2025 addressing genes in the OXT/AVP pathway related to ASD were included. Data were extracted from 17 selected articles considering country, year, genes, polymorphisms, association with ASD, and the use of treatment or biomarker identification. The results indicated that the most researched polymorphisms were rs2254298 and rs53576 of the OXTR gene, in addition to suggesting the identification of polymorphisms in the OXTR, AVPR1a, and AVPR1b genes as potential biomarkers of risk and severity of social symptoms, as well as the exploration of intranasal OXT as a promising therapeutic approach. In conclusion, it has been demonstrated how the oxytocinergic and vasopressinergic pathways significantly participate in mediating social cognition, and that their genetic alterations are directly implicated in the core symptoms of ASD. Furthermore, promising avenues for interventions based on genetic biomarkers have been indicated, contributing to a more precise and individualized future approach to autism treatment.
Antígeno leucocitário humano (HLA) e a leucemia mieloide aguda: uma revisão integrativa
(Universidade Federal de Goiás, 2025-11-25) Souza, Andressa Evangelista de; Alcântara, Keila Correia de; Alcântara, Keila Correia de; Silva, Daniella Alves; Negreiros, Maryana dos Santos
The human leukocyte antigen (HLA) system is a set of highly polymorphic genes, fundamental for immunological recognition and for distinguishing between self and non-self . Due to its central role in antigen presentation, HLA has been extensively investigated for its influence on susceptibility to various diseases, including hematological malignancies. Among these, Acute Myeloid Leukemia (AML) stands out, characterized by the proliferation of immature myeloid cells that compromise normal blood production and is associated with high relapse and mortality rates. In this sense, the identification of genetic markers, such as HLA alleles, has gained increasing relevance for prognosis and personalized medicine. Thus, this review aims to analyze the f requency of HLA alleles in patients with AML and their possible association with the development and prognosis of the disease. The research was conducted using the PubMed, Web of Science, and Scopus databases, considering publications in English between 2015 and 2025. Initially, 383 articles were identified, of which 23 met the inclusion criteria established for this study. The results showed that dif ferent alleles of the HLA system influence susceptibility to AML, acting as predisposing or protective factors. For example, alleles such as HLA-B*40 and HLA-C*01 showed a protective ef fect, while HLA-A*32 and HLA- B*27 were associated with a higher risk. It was also observed that the influence of alleles varies according to population origin, genetic context, and haplotype combinations. Furthermore, HLA haplotype blocks and functional interactions with immune receptors, such as KIR/HLA-I combinations, proved important in explaining the genetic variability associated with the disease, complementing the analysis of isolated alleles. However , there are still gaps in the literature related to methodological standardization, sample size, and population diversity in studies. Therefore, broader and more integrated studies are needed to better understand the role of HLA in AML and apply it to immunogenetics and the development of personalized clinical approaches.
Biomateriais poliméricos: curativos de hidrogéis e hidrocolóides na cicatrização de lesões cutâneas de diferentes origens: um estudo de revisão
(Universidade Federal de Goiás, 2025-11-28) Santos, Isabelly Aida Folador; Paula, Luiza Gabriella Ferreira de; Silva, Artur Christian Garcia da; Silva, Artur Christian Garcia da; Jesuino, Rosalia Santos Amorim; Menezes, Rafaela Campos de
Hydrogels and hydrocolloids represent a class widely studied within biomaterials science due to their particular properties. Both, when applied to wound healing, promote the maintenance of a moist environment and optimize the healing cascade. Hydrogels, with their three-dimensional network, allow the incorporation and release of bioactive substances into the wound due to their unique structure. Hydrocolloids, on the other hand, are made from carboxymethylcellulose, pectin, gelatin, and alginate, which form a colloidal network and mainly act as a protective barrier and absorbent dressing. Skin healing is a dynamic process that involves inflammation, proliferation, and remodeling phases to repair damaged tissue. This process can be influenced by several factors, including the choice of dressing. The studied dressings work in each phase of this process, maintaining a moist environment, accelerating reepithelialization, and serving as a barrier against infections. In general, dressings that promote moist healing are considered the gold standard in clinical practice; however, they are not recommended for all wounds and are more suitable for low-exudate wounds, such as those analyzed in this study. This study aimed to review the scientific literature on the use of hydrogels and hydrocolloids in the healing of skin wounds from different origins. A review was conducted based on 108 articles retrieved from the PubMed and Scopus databases, published in the last five years. The included articles generally address skin lesions caused in preclinical trials, burn injuries, postoperative wounds, ulcerative wounds, acne lesions, and others. The evidence indicates that hydrogels and hydrocolloids have demonstrated efficacy in the healing process, reducing healing time, controlling inflammation, and improving the quality of scars or regenerated skin. Thus, hydrogels and hydrocolloids are established as safe, effective options with high potential for clinical and therapeutic application in wound healing.
Diagnóstico da detecção e avaliação da sucessão ecológica no Cerrado com dados do MapBiomas
(Universidade Federal de Goiás, 2025-12-04) Assunção, Ana Paula Carlos; Silva, Alessandra Bertassoni da; Silva, Ana Paula Matos e; Silva, Ana Paula Matos e; Silva, Alessandra Bertassoni da; Dias, Luiz Gabriel Barbosa; Silva, Bárbara Costa da
The Cerrado biome, the most biodiverse savanna in the world, is under intense pressure from land use and land cover conversion, requiring monitoring of its ecological succession dynamics. This study aimed to analyze the MapBiomas time series to qualify ecological succession processes based on the ambiguous Land Use Mosaic class (Class 21), which represents areas in initial regeneration. The methodology focused on analyzing the temporal trajectory of pixels and the increase in the Normalized Difference Vegetation Index (NDVI) as an indicator of vegetation structure.The analysis demonstrated the effectiveness of the method in overcoming the spectral uncertainty of the Mosaic Use class, which presented 66% inconsistency in relation to the reference collection, by accurately detecting 54 transition points to natural vegetation. The consistent permanence of the natural vegetation class after the conversion of Land Use Mosaic and the increase in NDVI over the years corroborated the two hypotheses, confirming that the transitions captured represent a structural establishment of vegetation and not mere spectral fluctuations.The results reveal that 88.89% of the succession processes detected are of anthropogenic origin, highlighting the natural resilience potential of the Cerrado in areas previously used for agriculture and livestock. The study, however, warns of the risk of overestimating the natural areas of the biome, since 10.37% of the points were mistakenly classified as natural, reinforcing the need for temporal consistency criteria. This diagnosis fills scientific gaps by providing a robust methodology that addresses the spatial heterogeneity of the biome, offering a solid basis for improving future versions of MapBiomas and for more effective recovery and conservation policies.
Morfologia polínica de representantes da tribo Microlicieae (Melastomataceae) e suas implicações taxonômicas
(Universidade Federal de Goiás, 2026-01-13) Melo, Ana Luiza do Nascimento; Pires, Ana Carolina Mezzonato; Pires, Ana Carolina Mezzonato; Souza, Raquel Maria Batista Souza de; Souza, Mariana Albuquerque de
The tribe Microlicieae has undergone several changes in its circumscription throughout its taxonomic history, having been analyzed and morphologically described over time. The study by Versiane et al. (2021) proposed the inclusion of the genera Chaetostoma, Lavoisiera, Stenodon, and Trembleya within Microlicia sensu lato. The objective of the present study is to perform a morphological analysis of pollen grains from the genera Chaetostoma, Lavoisiera, Stenodon and Trembleya in order to obtain a palynological perspective on the new taxonomic circumscription of Microlicia s.l. Botanical material was obtained from specimens catalogued in the Herbarium of the Federal University of Goiás (UFG), through the collection of anthers or viable floral buds for analysis, using forceps and a stereomicroscope. The pollen grains of the analyzed Microlicieae species occur as monads, are isopolar, and small in size. The aperture system consists of three pseudocolpi alternating with three colpori, and in M. selaginea (under light microscopy) the occurrence of syncolpate colpori may be observed. Regarding shape, pollen grains range from prolate-spheroidal to perprolate, with a DP/DE ratio between 1.1 and 2.9. The polar diameter ranges from approximately 15.3 to 22.3 μm, and the equatorial diameter from 7.5 to 17.3 μm. Sexine ornamentation is variable and may be densely rugulate, rugulate, slightly rugulate, psilate, or psilate–rugulate. The results indicate that pollen grains of the family Melastomataceae do not differ markedly in their morphology, mainly expressing the presence of pseudocolpi alternating with colpori as a distinctive feature in the palynotaxonomy of the family. It is concluded that palynology represents an important tool in taxonomic studies, contributing to the reconstruction of evolutionary histories and to the proposal of new taxonomic circumscriptions.
Análise de mel e de potes de pólen de Scaptotrigona postica (Latreille, 1807) do meliponário da Universidade Federal de Goiás
(Universidade Federal de Goiás, 2026-01-13) Nascimento, Isadora Araújo; Pires, Ana Carolina Mezzonato; Pires, Ana Carolina Mezzonato; Mendonça, Cláudia Barbieri Ferreira; Teixeira, Gabriel Henrique Gomes de Souza Freitas
Stingless bees of the subfamily Meliponinae play a fundamental role in pollination and in the maintenance of biodiversity, relying on nectar and pollen as their main sources of energy and protein. Melissopalynology is an important tool for understanding interactions between bees and plants, as it allows the identification of the botanical origin of the resources used and the characterization of local flora. This study aimed to describe the pollen types present in honey and pollen pot samples of Scaptotrigona postica (Latreille, 1807) from a meliponary located at the Federal University of Goiás, in Goiânia, Goiás, Brazil. The samples were subjected to acetolysis and analyzed under light microscopy, with a total count of 2,400 pollen grains following standardized methodology. Different pollen types were identified, with a predominance of the family Fabaceae in both honey and pollen pot samples, followed by Myrtaceae, Melastomataceae, and Anacardiaceae, varying according to sample type. The results indicate variation in the use of floral resources and highlight the generalist foraging behavior of the species, with preference for certain botanical families. This study contributes to knowledge of the local flora and the foraging behavior of Scaptotrigona postica (Latreille, 1807), and reinforces the importance of vegetation conservation and sustainable meliponiculture practices.
A influência do tamanho e agregação dos fragmentos sobre a ocorrência de Lobo-Guará em unidades de conservação no Cerrado
(Universidade Federal de Goiás, 2025-12-05) Silva, Giovana Muniz Medeiros da; Bravo, Isabella Tahyana Avelar; Marco Júnior, Paulo De; Lion, Marília Bruzzi; Novaes, Marisa de Oliveira
Biodiversity hotspots are regions with a high wealth of endemic species that were under serious threat of habitat loss, identified with the aim of prioritizing conservation efforts. The Cerrado was characterized as a biodiversity hotspot in the 2000s due to the significant loss of its original vegetation cover and because it is home to more than a thousand endemic vascular plant species, representing one of the most diverse biomes with a loss of more than fifty percent of its original vegetation cover converted. The objective of this study is to assess the habitat of the species Chrysocyon brachyurus, the maned wolf, in Conservation Units in the Cerrado, as well as to assess the aggregation and amount of habitat in the landscape in these protected areas. The study considered that landscape characteristics, such as the degree of aggregation and the size of fragments, may influence the presence of the species. In Conservation Units where the species occurs, it was observed that the areas tend to be more continuous and less fragmented. It was also observed that Conservation Units with a high percentage of habitat in the landscape tend to have high aggregation, which favors more than one occurrence of the species remaining within the same habitat fragment. For this purpose, we used R software for landscape analysis and statistical analysis. We used occurrence points to relate them to Conservation Units, using the Effective Mesh Size (MESH) metric, in addition to the Percentage of Landscape (PLAND) metric, both metrics from the landscapemetrics package. MESH enabled us to assess the degree of landscape continuity and subdivision, while PLAND quantified the proportion of habitat in the study area, allowing us to relate this information to the interpretation of habitat in protected areas. We performed a linear regression to relate the amount of habitat in the Conservation Units to the landscape aggregation metric and a t-test to assess whether protected areas with confirmed occurrences are different from protected areas without occurrences. In this way, it is possible to discuss the continuity and aggregation of land use and land cover classes that the maned wolf considers as habitat in the Cerrado. These are important factors for both conservation and management of protected areas in the biome.
Levantamento de borboletas frugívoras (Lepidoptera: Nymphalidae) na Serra da Mesa, Goiás
(Universidade Federal de Goiás, 2025-06-27) Castro, Sofia Gomes da Cruz e; Oliveira, Sarah Siqueira de; Marco Júnior, Paulo De; Marco Júnior, Paulo De; Lion, Marília Bruzzi; Fachin, Diego Aguilar
Understanding the distribution of biological diversity is essential for any conservation strategy. In the context of Neotropical ecosystems, biodiversity records for the Cerrado are limited, and vast areas of the state of Goiás remain unassessed in terms of their fauna and flora. To help fill this gap, a survey of fruit-feeding butterflies of the family Nymphalidae was conducted in the Vale da Serra da Mesa region, rural zone of Niquelândia (GO). Passive sampling was carried out in July, August, October, and November 2024 using modified Van Someren-Rydon traps, which were deployed in the field for two days and checked every 24 hours. Captured specimens were euthanized, properly prepared, photographed, and incorporated into the entomological collection of the Federal University of Goiás (UFG). A total of 52 Nymphalidae butterflies were collected, distributed across 14 genera, with higher abundance recorded during the dry months. In addition to a species list organized by tribe and subfamily, this study provides dorsal and ventral photographs of all collected individuals, aiming to support future research and conservation initiatives focused on the biodiversity of the Cerrado.

The interactions between plants and pollinators regulate a fundamental ecosystem function, in which bees and plants mutually benefit. Bee species can exhibit varying degrees of dietary specialization: oligolectic (with pollen diets restricted to one family or genus) and polylectic (a broader pollen diet with multiple plant families). This plant-pollinator relationship depends on the synchrony between the bees' life cycle and the flowering perioda synchrony threatened by thermal variations, which may particularly affect oligolectic species due to their specialized strategy. Species with lower thermal tolerance may be more susceptible. However, little is known about specialist species in a climatic context, and few studies integrate thermal niche data for Neotropical species. To investigate whether the thermal niche breadth of Brazilian bees is related to their larval dietary specialization, we selected 20 species (9 specialists and 11 generalists) of native bees from the Neotropical region (Brazil), belonging to the tribes Augochlorini, Eucerini, Megachilini, and Meliponini, ranging from crop pollinators to specialists in native flora, with minimum and maximum temperature data from an occurrence database. The results indicate that oligolectic species exhibited a narrower thermal niche breadth than polylectic species. These findings highlight the greater vulnerability of oligolectic species to climate change. Such discoveries underscore the importance of future investigations to deepen the understanding of these differentiated ecological responses in the context of constant global warming, emphasizing the need for research to ensure their persistence in the face of accelerated climate change.
Microcefalia com craniossinostose: um relato de caso
(Universidade Federal de Goiás, 2025-06-26) Pereira, Júlia Lopes; Araújo, Rafael Ferraz; Guimarães, Nilza Nascimento; Guimarães, Nilza Nascimento; Araújo, Rafael Ferraz; Figueiredo, Augusto César Ribeiro; Oliveira, Kleber Mirallia de
This study describes an unusual autopsy finding at the Legal Medical Institute (LMI) in Goiânia, about an eight-month-old infant with premature and complete closure of the cranial sutures. The absence of additional deformities or associated genetic syndromes highlights the uniqueness of the case. Early closure of the sutures restricted brain growth, resulting in severe microcephaly and possibly indirectly contributed to death, caused by pulmonary sepsis after bronchoaspiration. The literature review highlighted the scarcity of similar reports, underscoring the importance of anatomical documentation of rare cases to advance the understanding of cranial malformations and their clinical impacts.
Uso de habitat pela avifauna do lago da agronomia, Campus Samambaia, Universidade Federal - UFG, Goiânia- GO
(Universidade Federal de Goiás, 2025-06-23) Bossi, Vinicius Marques; Bianchi, Carlos Abs da Cruz; Bianchi, Carlos Abs da Cruz; Oliveira, Arthur Angelo Bispo de; Marco Júnior, Paulo De
The Cerrado, one of the most biodiverse biomes in the world, harbors rich fauna, with an emphasis on aquatic birds that play important ecological roles. The increasing threat to biodiversity due to habitat fragmentation highlights the need for studies that investigate these ecosystems, such as the Lago da Agronomia at the Federal University of Goiás (UFG). This study aims to identify the bird species present at Lago da Agronomia and understand their interactions with the local ecosystem. The research was conducted at Lago da Agronomia, with data collected during the morning and afternoon periods using point count and visual observation sampling methods. Data were collected from three strategic points along the lake. Species identification was assisted by binoculars and field guides, and the abundance of each species was quantified using R software functions. Nine bird species were observed, with Egretta thula being the most abundant. The distribution of species varied between shifts and locations, with the lakeshore being the environment with the highest abundance of individuals. The study suggests that environmental factors, such as riparian vegetation, may influence the distribution and abundance of species. Differences in abundances between species suggest specific ecological preferences. The importance of Lago da Agronomia as a crucial habitat for aquatic birds is highlighted, emphasizing the need for conservation strategies. The study provides a report on species occurrence and habitat occupancy by the birds, stressing the need to protect these wetlands to ensure the maintenance of biodiversity and essential ecosystem services.

(Universidade Federal de Goiás, 2025-07-28) Cordeiro, Talline Sousa; Bianchi, Carlos Abs da Cruz; Bianchi, Carlos Abs da Cruz; Ribeiro, Ana Carolina Da Cunha; Stevaux, Maria Nazaré
The maned wolf (Chrysocyon brachyurus) is the largest canid in South America and displays an omnivorous diet characterized by notable feeding plasticity. This study presents an integrative literature review aiming to assess the species’ dietary composition, with focus on seasonal, regional, and ecological variations. A total of 19 scientific studies published between 1994 and 2025 were analyzed, most of which employed fecal analysis methods. The results revealed a diet composed mainly of native fruits, especially Solanum lycocarpum, and small vertebrates such as rodents, along with occasional invertebrates and anthropogenic items. Seasonal dietary shifts were evident, with a broader food niche in the rainy season and more specialized feeding during the dry season. Regional variations were also influenced by habitat type and levels of human disturbance. The maned wolf’s dietary flexibility highlights its ecological role as a seed disperser and population regulator of small vertebrates, reinforcing its importance for conservation strategies, particularly within the Cerrado biome.
Flora vascular da área de relevante interesse ecológico de Santa Helena, PR
(Universidade Federal de Goiás, 2025-06-27) Moura, Sara Dias; Santos, Leonardo Biral dos; Santos, Leonardo Biral dos; Teles, Aristônio Magalhães; Pires, Ana Carolina Mezzonato
The National System of Conservation Units (SNUC) establishes that every Conservation Unit (UC) must have a management plan, a technical document that delineates it and sets the rules for use and management. However, several UCs lack this plan or present it inadequately, for example, with incomplete floristic lists. Floristic surveys in UCs are essential to provide primary and quality data about local real biodiversity. The objective of this study was to conduct a broad floristic survey of the Santa Helena Relevant Ecological Interest Area (ARIE-SH), a UC created by Itaipu Binacional in the 1980s in western Paraná. The survey also aimed to provide data for the new Management Plan, currently being updated, and to incorporate the species list into the "Catálogo de Plantas das Unidades de Conservação do Brasil" project. The ARIE-SH covers approximately 1.480 hectares and is located in the homonymy city, along the banks of the Paraná River on the border with Paraguay. The UC is situated in the Atlantic Forest domain and is covered by Seasonal Semideciduous Forest in various successional stages. Collections took place over 33 visits between November 2016 and September 2024 and are deposited in the SHPR herbarium with duplicates in the UFG herbarium. The samples were identified using specialized literature, comparisons with online herbaria exsiccates, and consultation with specialists. The species were evaluated regarding their habit, origin, and conservation status. Additionally, the results were compared to the species list of the current Management Plan, from 2010. 214 species were found, between collections and secondary data, distributed across 69 families, with emphasis on Fabaceae (25) and Asteraceae (13). Most of the species are herbaceous (31.78%), followed by arboreal habit (29.91%) and climbing (20.56%). We recorded 201 native species, with 15 considered endemic to Brazil, and 13 exotic, of which ten are naturalized and three cultivated. Thirteen species are classified as threatened at the national and state levels. Compared to the current Management Plan, there are only 40 families and 31 species in common. Our survey inventoried 183 previously unrecorded species, representing almost a 100% increase over the current list. The survey contributed to the knowledge of the regional flora, and the results fill existing gaps in the floristic knowledge of the ARIE-SH. This study emphasizes the importance of updating floristic lists in management plans and the deposit of botanical material in herbaria.
Poleiros artificiais como facilitadores da restauração ecológica: uma revisão integrativa baseada em chuva de sementes, avifauna e uso do solo

Brazil is considered a megadiverse country but faces serious threats due to fragmentation and the loss of native areas, making effective techniques for ecosystem recovery essential. Among these techniques, artificial perches stand out as simple and low-cost structures that act as catalysts for ecological restoration by attracting seed-dispersing birds and increasing seed deposition in degraded areas, thus accelerating the succession of local plant communities. This study compiles and analyzes 19 Brazilian works investigating the effectiveness of artificial perches across different biomes, especially in the Atlantic Forest, highlighting their potential to enhance floristic diversity and promote connectivity between forest fragments. However, it was not possible to confirm a direct relationship between land use type and the success of the technique, due to the lack of methodological standardization and insufficient detailed data in many studies. The effectiveness of perches depends on factors such as model, structure, height, location, proximity to forest remnants, and landscape characteristics. For their installation, a prior environmental assessment is recommended, including the classification of the regeneration potential of the area, appropriate selection of perch models, and strategic placement between 60 and 150 meters from native fragments, especially in areas requiring additional interventions. Despite existing challenges, artificial perches represent a promising strategy for ecological restoration, particularly due to their simplicity, low cost, and ability to facilitate natural regeneration processes in fragmented landscapes.
Experimentos ecológicos com macrófitas no Brasil: uma revisão sistemática

Aquatic macrophytes are of utmost importance to aquatic communities and to humans and are essential bioindicators of water quality. Experiments involving these aquatic plants help us to understand different ecological aspects of this community and the functioning of the aquatic ecosystem. Systematic reviews are essential to systematize the knowledge produced on these issues, so that we can identify which effects of macrophytes are most studied and also identify knowledge gaps that can be further explored through experiments with macrophytes. Thus, we conducted a systematic review of experiments with macrophytes conducted in Brazil, analyzing the species and design used in these experiments and the ecological themes studied. To this end, we conducted a bibliographic search on the Web of Science and Scielo Brazil platforms, selected articles related to the topic and collected relevant information from them. In total, we analyzed 13 articles in full, which experimentally manipulated 14 distinct species of macrophytes, most of them submerged. Our results showed that most studies have occurred since the year 2009 and have analyzed the effect of aquatic macrophytes on the planktonic community (zooplankton and phytoplankton) and fish. In addition, the most studied theme was predator-prey interaction. Finally, most experiments were conducted on a mesocosm scale. We conclude, therefore, that there are research gaps in experimental studies with macrophytes in the areas of biological invasion, ecosystem functions, and studies involving aquatic insects. Investment in science and research is essential to address these knowledge gaps.
Aspectos ecológicos das aves de rapina: um levantamento atual sobre dieta, reprodução e comportamento
(Universidade Federal de Goiás, 2025-06-23) Pereira, Gabriel Simões Coelho; Bianchi, Carlos Abs da Cruz; Bianchi, Carlos Abs da Cruz; Jesus, Shayana de; Regolin, André Luís
Birds of prey represent one of the most emblematic and, at the same time, least studied groups on the planet. Many of their species lack basic information regarding their ecology and natural history, which hampers the development of effective conservation strategies. This study aimed to assess the current state of scientific knowledge on birds of prey, with a focus on species occurring in the Cerrado biome. The methodology involved a review of scientific literature, gathering data on diet, behavior, and reproduction. The results reveal a significant lack of ecological information, particularly concerning endemic species or those with restricted distributions in the Cerrado. This scenario highlights the urgent need to expand research efforts focused on the ecology of birds of prey, in order to support more effective conservation actions.
Efetividade do licenciamento ambiental em Goiás
(Universidade Federal de Goiás, 2025-06-27) Santos, Lucas Calacia Martins dos; Silva, José Antônio Tietzmann e; Silva, José Antônio Tietzmann e; Pinto Neto, Geraldo Miranda; Silva, Leonardo Felippe Pereira Gonçalves
This study evaluated the effectiveness of the environmental licensing system in the State of Goiás in the period following State Law No. 20.694/2019, confronting the legal-institutional framework with the dynamics of native vegetation suppression in the Cerrado biome. The research, characterized as qualitative-quantitative and descriptive-analytical, was based on a legal-documentary analysis of Goiás environmental legislation, a survey of administrative data from the State Secretariat for Environment and Sustainable Development (SEMAD-GO), and the collection of deforestation data via remote sensing (MapBiomas and PRODES/INPE) for the period 2019-2024. The study revealed a profound dissonance between formal environmental governance and practical results in the territory. A central paradox was identified: a relatively low number of licenses for vegetation suppression were issued by SEMAD-GO, while remote sensing indicators pointed to a high and increasing rate of deforestation in the same period, driven by the expansion of agribusiness. It was concluded that the new normative arrangement in Goiás, although efficient in its purpose of streamlining and accelerating procedures, proves ineffective in its ultimate goal of environmental protection, failing to curb the loss of native vegetation. The pursuit of efficiency appears to have compromised effectiveness, increasing the risk that environmental licenses become a mere formal ritual devoid of practical impact in containing degradation vectors. The study's limitations, such as difficulty in accessing georeferenced licensing data and the exclusion of other degradation factors (e.g., fire), suggest future research that deepens spatial correlation and integrates multiple variables for a more comprehensive understanding of environmental effectiveness.

The objective of this study is to analyze how climate change may disrupt the existing ecological interactions between the plant species Vochysia rufa and its pollinators. Additionally, the study aims to assess the effectiveness of Protected Areas (Conservation Units) in safeguarding these species in the face of land-use changes. The methodology is based on the analysis of species distribution data, which were collected from Google Scholar and Web of Science, and matched with current climate data from WorldClim and future climate data comparing scenarios of high and low environmental governance. For the plant model, soil data from SoilGrids were also included. All variable modeling was performed in RStudio using the ENMTML package. The overlapping area between the distributions of the plant and its pollinators was assessed in relation to their presence within Protected Areas, allowing the evaluation of whether the current protected area system is capable of ensuring the future conservation of these species. It is expected that there will be a mismatch between the distributions of Vochysia and its pollinators, as climate change progresses, pollinators may shift to more suitable areas, while the plants may not, especially considering the limitations imposed by soil. Moreover, it is expected that under scenarios of higher governance, there will be less distributional loss. In addition, Protected Areas are expected to protect both species, as they both currently have a wide geographical distribution.
