How ecological niche breadth evolves is central to adaptation and speciation and has been
a topic of perennial interest. Niche breadth evolution research has occurred within …

Ecological opportunity–through entry into a new environment, the origin of a key innovation
or extinction of antagonists–is widely thought to link ecological population dynamics to …

Biological rules describe general morphological, structural and genetic patterns within and
across species. Within these, ecogeographical rules correlate phenotypic variation of …

Both predation and individual variation in life history traits influence population dynamics.
Recent results from laboratory predator–prey systems suggest that differences between …

Based on geographical and home range sizes, physiology, and gape limitation, a positive
relationship between predator size and diet breadth is expected. Alternatively, larger …

Conserving large carnivores is controversial because they can threaten wildlife, human
safety, and livestock production. Since large carnivores often have large ranges, effective …

Surprisingly, little is known about body‐size evolution within the most diverse amphibian
order, anurans (frogs and toads), despite known effects of body size on the physiological …

Tyrannosaurids were large carnivorous dinosaurs that underwent major changes in skull
robusticity and body proportions as they grew, suggesting that they occupied different …

Squamate reptiles (lizards and snakes) are a diverse clade in which there appear to have
been multiple origins of many remarkable traits, including (a) parthenogenetic …

The niche expansion and niche variation hypotheses predict that release from interspecific
competition will promote niche expansion in depauperate assemblages. Niche expansion …
