Walk, swim or fly? Locomotor mode predicts genetic differentiation in vertebrates.

abstract：:Legumes capable of fixing atmospheric N2 are abundant and diverse in many tropical forests, but the factors determining ecological patterns in fixation are unresolved. A long-standing idea is that fixation depends on soil nutrients (N, P or Mo), but recent evidence shows that fixation may also differ among N2-fixing s...

abstract：:Refuge-mediated apparent competition was recently suggested as a mechanism that enables plant invasions. The refuge characteristics of introduced plants are predicted to enhance impacts of generalist herbivores on native competitors and thereby result in an increased abundance of the invader. However, this prediction ...

One reason for this is because in field experiments increases in respiration due to warming are relatively short-lived. The explanations proposed for this ephe...
