Resumo
Ongoing environmental changes are affecting physical, chemical and
biological soil components. Evidence of impacts of soil changes on pollinators’
and seed dispersers’ behaviour, fitness and density is scarce, but growing.
Here, we reviewed information on such impacts and on a number of mechanisms
that may explain its propagation, taking into account the full range of
resources required by the large and diverse number of species of these two
important functional groups.We showthat while there is substantial evidence
on the effects of soil nitrogen enrichment and changes in soil water content on
the quality and quantity of floral and fruit resources, little is known on the
effects of changes of other soil properties (e.g. soil pH, soil structure, other
nutrients). Also, the few studies showing correlations between soil changes
and pollinator and seed disperser foraging behaviour or fitness do not clearly
identify the mechanisms that explain such correlation. Finally, most studies
(including those with nitrogen and water) are local and limited to a small
number of species, and it remains unclear how variable such effects are
across time and geographical regions, and the strength of interactive effects
between soil properties. Increasing research on this topic, taking into consideration
how impacts propagate through species interaction networks, will
provide essential information to predict impacts of ongoing environmental
changes and help guide conservation plans that aim to minimize impacts on
ecosystem functioning.
This article is part of the theme issue ‘The role of soils in delivering
Nature’s Contributions to People’.
