摘要:
iba clamitans) provide seed dispersal services for a wide assemblage of plant species in both small and large Atlantic forest fragments. Although

摘要:
with increasing urbanization intensity in landscapes. In addition, the effect of urbanization intensity on forest birds manifested most strongly at larger
Data from: Bergmann's body size rule operates in facultatively endothermic insects: evidence from a complex of cryptic bumblebee species

doi:10.5061/dryad.41k5c
摘要:
According to Bergmann’s rule we expect species with larger body size to inhabit locations with a cooler climate, where they may be well adapted

摘要:
and the degree of size symmetry is larger. Despite significant patterns, relative testes mass and gizzard complexity together explain < 10% of the var
Data from: Size matters: male and female mate choice leads to size-assortative pairing in a coral reef cardinalfish

Assortative pairing Matching Mate choice Paternal care Cardinalfish Coral Reefs
DOI:
doi:10.5061/dryad.4mf63
摘要:
larger males because they can successfully brood all of their eggs. Mutual mate choice will likely explain size-assortative pairing in other fish species

摘要:
and larger trees than lower-income communities, which in turn, attracted nearly five times the density of feeding birds. Foraging birds strongly prefer

摘要:

Data from: Nonrandom, diversifying processes are disproportionately strong in the smallest size classes of a tropical forest

摘要:
ecology holds that patterns of relative abundance among mature trees are largely set by processes operating at the earliest life cycle stages. Several studies
