The ultimate-level factors that drive the evolution of mating systems have been well studied,
but an evolutionarily conserved neural mechanism involved in shaping behaviour and social …

In recent years great strides have been made for improving our understanding of the
evolutionary relationships among neotropical cichlids, particularly within the clade Heroini …

Understanding the origin of biodiversity requires knowledge on the evolutionary processes
that drive divergence and speciation, as well as on the processes constraining it …

Abstract In The Ultimate Betrayal: Is There Happy Meat?, Bohanec proposed that farmed
animals raised humanely may experience betrayal when slaughtered. I argue based on …

In biparental species, the costs and benefits of parental investment can vary between the

The hyperdiverse freshwater fish family Cichlidae accounts for approximately 10% of today's
teleost diversity. For decades, researchers have been thrilled by their enormous diversity in …

While territorial aggression is a prerequisite for reproduction in many animals, individuals
need to balance its benefits against the costs. Territorial neighbours can influence these …

For many species parental behavior is essential for the survival of the offspring. While the
ultimate causes of teleost parental behavior have been widely studied, comparatively little is …

Successful territory defence is a prerequisite for reproduction across many taxa, and often
highly sensitive to the actions of territorial neighbours. Nevertheless, to date, assessments of …

The California grunion, Leuresthes tenuis (Ayres, 1860), like its sister species, the Gulf
