Mechanisms that generate brain size variation and the consequences of such variation on
ecological performance are poorly understood in most natural animal populations. We use a …

Elucidating the selective forces shaping the diversity of vertebrate brains continues to be a
major area of inquiry, particularly as it relates to cognition. Historically brain evolution was …

Comparative animal studies have identified a trend toward a more global structural
organization as brains become larger, suggesting that brain regions grow in sync as …

Pacific salmon (Oncorhynchus spp.) hatch and feed in freshwater habitats, migrate to sea to
mature, and return to spawn at natal sites. The final, riverine stages of the return migrations …

Traits often do not evolve in isolation or vary independently of other traits. Instead, they can
be affected by covariation, both within and across species. However, the importance of …

Brain-body static allometry, which is the relationship between brain size and body size
within species, is thought to reflect developmental and genetic constraints. Existing evidence …

Links between contrasting ecological conditions and evolutionary shifts in neurosensory
components, such as brain and eye size, are accumulating. Whether selection operates in a …

Teleosts exhibit extensive, ongoing neuroproliferation within their brains even as adults,
which facilitates indeterminate growth and permits them to recover from injuries to their …

A morfologia é um dos principais componentes do fenótipo de um organismo. Os girinos
apresentam grande diversidade morfológica e comportamental, e ocupam uma ampla gama …

Brain activity reacts to environmental complexity within an individual's reaction norm. Brain
activity is highly energy demanding and a target for energetic trade-offs. Hence, cognition is …
