The genetic consequences of spatially varying selection in the panmictic American eel (Anguilla rostrata).
Our understanding of the genetic basis of local adaptation has recently benefited from the increased power to identify functional variants associated with environmental variables at the genome scale. However, it often remains challenging to determine whether locally adaptive alleles are actively maintained at intermediate frequencies by spatially varying selection. Here, we evaluate the extent ...
متن کاملRAD-Seq Reveals Patterns of Additive Polygenic Variation Caused by Spatially-Varying Selection in the American Eel (Anguilla rostrata)
The American Eel (Anguilla rostrata) has an exceptional life cycle characterized by panmictic reproduction at the species scale, random dispersal, and selection in a highly heterogeneous habitat extending from subtropical to subarctic latitudes. The genetic consequences of spatially-varying selection in this species have been investigated for decades, revealing subtle clines in allele frequency...
متن کاملDraft genome of the American Eel (Anguilla rostrata).
Freshwater eels (Anguilla sp.) have large economic, cultural, ecological and aesthetic importance worldwide, but they suffered more than 90% decline in global stocks over the past few decades. Proper genetic resources, such as sequenced, assembled and annotated genomes, are essential to help plan sustainable recoveries by identifying physiological, biochemical and genetic mechanisms that caused...
متن کاملKidney function of the American eel Anguilla rostrata.
Urine formation in the eel, acclimated to freshwater (FW) and seawater (SW) was studied. SW eels maintained higher plasma and urine osmotic and ionic concentrations than FW eels. Polyethylene-1,2-glycol-14C (PEG-14C) clearance was 29% greater than methoxy-inulin-3H clearance. PEG-14C clearance was considered to be the glomerular filtration rate (GFR). The GFR of SW and FW eels did not differ. U...
متن کاملStructure and function of the isolated hemoglobins of the American eel, Anguilla rostrata.
Two electrophoretic hemoglobin patterns occur in hemolysates from the American eel, Anguilla r&rata. Type I hemolysates have two major components, I-F and I-S. Type II hemolysates have three major components, II-F, II-M, and II-S. Each kind of hemolysate also has at least one minor electrophoretic component. Amino acid analysis and tryptic peptide patterns of the isolated polypeptide chains ind...
