Can Diversifying Selection Be Distinguished from History in Geographic Clines? A Population Genomic Study of Killifish (Fundulus heteroclitus)
A common geographical pattern of genetic variation is the one-dimensional cline. Clines may be maintained by diversifying selection across a geographical gradient but can also reflect historical processes such as allopatry followed by secondary contact. To identify loci that may be undergoing diversifying selection, we examined the distribution of geographical variation patterns across the rang...
متن کاملEndocrinological Studies on the Euryhaline Killifish, Fundulus Heteroclitus (Linn.) **
The common killifish of the eastern United States, Fundulus heteroclitus (Linn.), is widely employed as an experimental animal by zoologists, em-bryologists, and comparative physiologists. The late Dr. Myron Gordon8' points out that it is a hardy species of convenient size, readily caught in tidal pools but not usually bred in aquaria for purposes of raising the stock. Dr. Gordon warns against ...
متن کاملCloning and functional expression of an MIP (AQP0) homolog from killifish (Fundulus heteroclitus) lens.
The major intrinsic protein (MIP) of lens fiber cells is a member of the aquaporin (AQP) water channel family. The protein is expressed at very high levels in lens fiber cells, but its physiological function is unclear. By homology to known AQPs, we have cloned a full-length cDNA encoding an MIP from the lens of killifish (Fundulus heteroclitus). The predicted protein (263 amino acids; GenBank ...
متن کاملA novel aquaporin 3 in killifish (Fundulus heteroclitus) is not an arsenic channel.
The Atlantic killifish (Fundulus heteroclitus) is a model environmental organism that has an extremely low assimilation rate of environmental arsenic. As a first step in elucidating the mechanism behind this phenomenon, we used quantitative real-time PCR to identify aquaglyceroporins (AQPs), which are arsenite transporters, in the killifish gill. A novel homolog killifish AQP3 (kfAQP3a) was clo...
متن کاملMechanisms and costs of mitochondrial thermal acclimation in a eurythermal killifish (Fundulus heteroclitus).
Processes acting at the level of the mitochondria have been suggested to affect the thermal limits of organisms. To determine whether changes in mitochondrial properties could underlie shifts in thermal limits, we examined how mitochondrial properties are affected by thermal acclimation in the eurythermal killifish, Fundulus heteroclitus - a species with substantial plasticity in whole-organism...
