Here, we report the draft genome sequence of Epilithonimonas sp. FP211-J200, isolated from rainbow trout head kidney cells. The size of the genome is 4,110,772 bp, with a G+C content of 37.1%. The Epilithonimonas sp. FP211-J200 genome has genes related to tetracycline and β-lactam resistance. This is the first reported Epilithonimonas species genome isolated from a fish host.

Hybridization between native and non-native species has serious biological consequences, but our understanding of how dispersal and selection interact to influence invasive hybridization is limited. Here, we document the spread of genetic introgression between a native (Oncorhynchus clarkii) and invasive (Oncorhynchus mykiss) trout, and identify the mechanisms influencing genetic admixture. In ...

Predation may be a significant factor in the divergence of sympatric species although its role has been largely overlooked. This study examines the consequences of predation on the fitness of a pair of lacustrine stickleback species (Gasterosteus aculeatus complex) and their F(1) hybrids. Benthic sticklebacks are found in the littoral zone of lakes associated with vegetation and bare sediments,...
