Next, the authors compared their stickleback results to previously published opsin genes in two related species of fish (bluefin killifish and black bream), separated from sticklebacks by millions of years, that had also adapted to blackwater and clearwater habitats.

In looking at killifish DNA from various lineages, one might expect to see a certain uniformity among them.

Stanford University scientists have found a new middle ground with the development of a genome - editing toolkit to study aging in the naturally short - lived African turquoise killifish.

African turquoise killifish live in temporary ponds of water in Zimbabwe and Mozambique that disappear with the dry season.

«One of our killifish mutants recapitulates, but in a rapid manner, a human disease called Dyskeratosis congenita, which is due to deficits in a complex involved in maintaining the end of chromosomes, or telomeres,» says lead author Dr. Itamar Harel, a postdoctoral research fellow in genetics.

Killifish live brutally short and efficient lives, sexually maturing in 3 weeks and dying within a few months.

When observing the colorful Turquoise killifish swimming in its aquarium, it is difficult to believe that it can serve as a model system for human aging; but it does.

The findings, posted online in advance of publication in the journal Environmental Science and Technology, are part of an ongoing collaborative effort to track the impacts of the Deepwater Horizon oil spill on Gulf killifish populations in areas of Louisiana that received heavy amounts of oil.

With researchers from Louisiana and South Carolina, the scientists found that Gulf killifish embryos exposed to sediments from oiled locations in 2010 and 2011 show developmental abnormalities, including heart defects, delayed hatching and reduced hatching success.

The researchers have tracked the impact of the oil on killifish since the Deepwater Horizon spill occurred in April 2010.

Atlantic killifish — common estuarine fishes about three inches long — are not only tolerating the toxic conditions in the harbor, they seem to be thriving there.

Researchers will look next at whether the adaptation affects how the killifish are able to respond to other kinds of stressors in their environment, such as low oxygen levels.

The new study looked at mate preferences in two species: rainwater killifish (Lucania parva) and bluefin killifish (Lucania goodei).

«There are a few protein variants that are common in New Bedford Harbor killifish, but uncommon elsewhere.

«Even though the specific molecular changes that are found in PCB - resistant tomcod and killifish are different, in both species AHR2 seems to be one of the genes — possibly the major gene — that is responsible for the resistance,» Hahn said.

The results suggest that evolution of resistance in independent populations of killifish converges on the same target gene.

«Solving an evolutionary puzzle: Atlantic killifish thriving in highly polluted water.»

Heritable adaptation and fitness costs in killifish (Fundulus heteroclitus) inhabiting a polluted estuary.

It lives in ponds, sharing its spot with Crawfish, Killifish, and Frogs.
