A team of U.S. National Science Foundation-funded scientists has identified at least 11 species of fish suspected to have land-walking abilities.The findings are based on CT scans and a new evolu...
Sex-changing fish exhibit differences in androgen receptor (AR) expression in muscles that are highly sensitive to androgens (male sex hormones) and essential for male courtship behavior, according to...
The sensory system in fish fins evolves in parallel to fin shape and mechanics, and is specifically tuned to work with the fish’s swimming behavior, according to new research from the University of Ch...
In a new study, researchers at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science examined how the interaction of two genomes in animal cells—the mitochondrial and nuclea...
Scientists once thought that being part of a community would protect animal populations from infectious disease outbreaks, but now they've learned otherwise, according to a study published this week i...
While a dominant male fish from northern Mexico mates with a female, a small fella bides his time in the offing. Suddenly, the little guy darts in ahead of Mr. Big and plants his seeds on freshly laid...
Evolutionary change in one trait can elicit evolutionary changes in other traits due to genetic correlations. This constrains the independent evolution of traits and can lead to unpredicted ecological...
A recent study provides new evidence that larvae swim faster, straighter and more consistently in a common direction when together in a group. The research led by scientists at the University of Miami...
Lightly brush your fingertips across your keyboard. What do you feel? The smoothness of plastic? Ridges, gaps, maybe a sticky key? Bumps on the F and J keys? The human fingertip is a finely tuned sens...
A Washington State University biologist has found the genetic mechanism that lets a fish live in toxic, acidic water. The discovery opens new insights into the functioning of other “extremophiles” and...
A new study offers insight into a process that could lead one species to diverge into two, researchers report in The American Naturalist.Avoidance of another species can lead female fish to avoid mati...
On June 22-24, 2015, the 5th Fish Passage Conference will be held for the first time in Europe, in the city of Groningen, The Netherlands. Hundreds of researchers, educators, practitioners, funders an...
The present experiment was conducted to evaluate the efficacy of dietary fermented by-product of mushroom, Pleurotus ostreatus, (FBPM) as a fish meal (FM) replacer in juvenile Amur catfish, Silurus as...
New findings published by researchers at the New York University Polytechnic School of Engineering are helping to unravel the complex interplay between alcohol and social behavior and may lead to new ...
Three experiments were conducted to evaluate the ME value, standardized ileal digestibility (SID) of amino acids (AA) of fish meal, and the effects of single cell protein (Prosin and Protide) replacin...
