A long‐standing macroecological hypothesis posits that species range limits are primarily
determined by abiotic factors (eg climate) at poleward boundaries and biotic factors (eg …

Spiny tailed iguanas are highly diverse clade of lizards in Mesoamerica, ranging from
northern Mexico through Panama. Utilizing 2 regions of mitochondrial DNA (1948 bp) and 4 …

Animals from different clades but subject to similar environments often evolve similar body
shapes and physiological adaptations due to convergent evolution, but this has been rarely …

Adaptive radiations garner considerable interest from evolutionary biologists. Lizard
radiations diversifying along structural niche space often exhibit distinct changes in body …

Tetrapod limbs have been used as a model system to investigate how selective pressures
and constraints shape morphological evolution. Anurans have had many independent …

Background Ecomorphological studies of lizards have increasingly employed comparison of
claw morphology among species in relation to spatial niche use. Typically, such studies …

Islands are hotspots of endemism and often function as engines of adaptive radiation.
Nevertheless, we lack a deep understanding of the processes that generate phenotypic …

Visual ornaments have long been assumed to evolve hyper‐allometry as an outcome of
sexual selection. Yet growing evidence suggests many sexually selected morphologies can …

Multiple octopus species inhabit overlapping ecohabitats worldwide yet little is known about
the behavioral mechanisms that facilitate such coexistence. To distinguish coexistence …

Economically-important watershed ecosystems are often threatened by anthropogenic
disturbances and remain important focal areas for long-term studies in support of sustained …
