Comparative studies on brain asymmetry date back to the 19th century but then largely
disappeared due to the assumption that lateralization is uniquely human. Since the …

Humans interact with fishes in many contexts including aquaculture, scientific study and
companion animals. In all of these contexts, fish welfare can be compromised through …

The principles of game theory apply to a wide range of topics in biology. This book presents
the central concepts in evolutionary game theory and provides an authoritative and up-to …

The origins of novel trophic specialization, in which organisms begin to exploit resources for
the first time, may be explained by shifts in behavior such as foraging preferences or feeding …

Identifying the evolutionary and developmental bases of adaptive phenotypes is of central
interest in evolutionary biology. Cichlid fishes have been a useful research model due to …

Lateral preference in behaviors has been widely documented in many vertebrates and
invertebrates. Such preferences are strange, puzzling, and on the surface, not adaptive …

The stable polymorphism in mouth asymmetry in the cichlid fish Perissodus microlepis is a
textbook example of adaptive evolution accomplished by functionally relevant morphological …

Behavioral laterality—typically represented by human handedness—is widely observed
among animals. However, how laterality is acquired during development remains largely …

Although parental care is known to occur in a wide range of teleost fishes, postnatal
provisioning of nutrition has been documented rarely. Here, we describe a novel example of …

Random asymmetry, that is the coexistence of left-and right-sided (or-handed) individuals
within a population, is a particular case of natural variation; what triggers and maintains such …
