Pollutants affected fish over multiple generations, according to researchers. Pollution from the production of antidepressant medication is altering fish behavior and reproductive traits, highlighting ...

Fish reproductive biology and ecology encompass a diverse range of phenomena from gametogenesis and spawning strategies to larval development and recruitment patterns. Recent studies have highlighted ...

A research team led by David Reznick, a professor of biology at UC Riverside, has found that as some populations of an organism evolve a longer lifespan, they do so by increasing only that segment of ...

There is a whole lot of plastic pouring into the ocean every day, and whole lot we don't know about the damage it causes. Looking to fill in these blanks is a team of Duke University scientists, who ...

Norwegian researchers show that the sperm of Arctic char, a cold-water fish common to alpine lakes, swim at different speeds in different fluids, depending on whether the fish are dominant or ...

Researchers from Institute of Science Tokyo present the underlying reasons behind the evolutionary bias in reproductive strategies of egg-care species. Using 240 whole genome sequences of fish species ...

In mosquitofish, of the genus Gambusia, male fish are smaller than females -- sometimes only half the size. Biologists had previously assumed that smaller male mosquitofish had at least some ...
