Increasing temperatures associated with climate change are predicted to cause reductions
in body size, a key determinant of animal physiology and ecology. Using a four‐decade …

Owl monkeys, genus Aotus, are distributed from Panama to the northeast of Argentina and
from the highlands of the Andes to the Atlantic coast. They are relatively small arboreal …

Dasypus is the most speciose genus of the order Cingulata, including approximately 40% of
known living armadillos. Nine species are currently recognized, although comprehensive …

Allometry has been the focus of growing interest in studies using geometric morphometric
methods to address a wide range of research questions at the interface of ecology and …

Trematodes can increase intraspecific variation in the phenotype of their intermediate snail
host. However, the extent of such phenotypic changes remains unclear. We investigated the …

Phylogeny reconstruction is an estimation of genealogical history, not an exact rendering of
it, and no method of phylogeny reconstruction is infallible. The cladistic relationships of the …

Phenotypic divergence between closely related species has long interested biologists. Taxa
that inhabit a range of environments and have diverse natural histories can help understand …

Understanding why species range sizes vary is important for predicting the impact of
environmental change on biodiversity. Here we use a multi‐variable approach in a …

Background Parasite attachment structures are critical traits that influence effective host
exploitation and survival. Morphology of attachment structures can reinforce host specificity …

Locomotory performance is an important determinant of fitness in most animals, including
flying insects. Strong selective pressures on wing morphology are therefore expected …
