Research on the behavior of animals in zoos has been conducted for decades and observations have provided information that has improved the psychological and social well-being of animals. However, research on fishes in zoos and aquariums seems to be

In The Ultimate Betrayal: Is There Happy Meat?, Bohanec (2013) proposed that farmed animals raised humanely may experience betrayal when slaughtered. I argue based on personal experience that humans often betray trust relationships with farmed animal

The co-occurrence of similar species in a particular environment may be facilitated if they specialise on different microhabitats, reducing competition between them. In some cases, two species prefer the same microhabitat, but one is competitively ex

The Rio Grande Cichlid, Herichthys cyanoguttatus, is native to northeastern Mexico and southern Texas and has been introduced at many places in the US. Recent research has indicated that the true identity of at least some populations of Herichthys cf

Invasions by Asian carps have become a high profile topic due to the threat they pose to native ecosystems and associated economies. One of four primary invasive Asian carp species, Grass Carp, Ctenopharyngodon idella (Cyprinidae), is commonly produc

Behavioral studies have often examined parental care by measuring phenotypic plasticity of behavior within a species. Phylogenetic studies have compared parental care among species, but only at broad categories (e.g., care vs. no care). Here we provi

Neuroendocrine pathways that regulate social behavior are remarkably conserved across divergent taxa. The neuropeptides arginine vasotocin/vasopressin (AVT/AVP) and their receptor V1a mediate aggression, space use, and mating behavior in male vertebr

SUMMARY Some fishes mature and function as one sex and later transform to the other sex in response to social interactions. Previous evidence suggested that a change in developmental timing may be involved in the evolution of adult sex change in fish
