摘要:
Both top-down (grazing) and bottom-up (resource availability) forces can determine the strength of priority effects, or the effects of spec

摘要:
in a protected area. 3. We quantified the relative influence of top-down and bottom-up factors on nest colonization, persistence (i.e., nest reuse) and success

摘要:
at night, at illuminance levels similar to roadside vegetation, can have population effects mediated by both top-down and bottom-up effects on ecosystems. Give

摘要:
We examined the importance of temporal variability in top-down and bottom-up effects on the accumulation of stream periphyton, which are complex

摘要:
the resource constraints for many herbivores and mesopredators. Variation in bottom-up conditions may also contribute to context dependence in apex predator effects.

摘要:
will not only depend on direct species-specific temperature effects, but also on indirect effects related to bottom-up and top-down processes. Here, we investigated
