Population structure of sea-type and lake-type sockeye salmon and kokanee in the Fraser River and Columbia River drainages.

open access: yesPLoS ONE, 2017
Population structure of three ecotypes of Oncorhynchus nerka (sea-type Sockeye Salmon, lake-type Sockeye Salmon, and Kokanee) in the Fraser River and Columbia River drainages was examined with microsatellite variation, with the main focus as to whether ...

MORPHOLOGICAL AND PRODUCTIVE CHARACTERISTICS OF TWO TSIGAIE ECOTYPES, USED AS GENETIC STOCK

open access: yesScientific Papers Animal Science and Biotechnologies, 2023
This paper investigates the morphological and productive characteristics of two Tsigaie ecotypes belonging to the red variety. They represent genetic stock and semen, oocytes and embryos will be harvested from them in order to be cryopreserved. The sheep

Polygenic adaptation from standing genetic variation allows rapid ecotype formation

open access: yes, 2023
Adaptive ecotype formation is the first step to speciation, but the genetic underpinnings of this process are poorly understood. While in marine midges of the genus Clunio (Diptera) reproduction generally follows a lunar rhythm, we here characterize two ...

Differential Activity of Coexisting Prochlorococcus Ecotypes

open access: yesFrontiers in Marine Science, 2019
The abundance and widespread distribution of the unicellular cyanobacterium Prochlorococcus is attributed to its extensive genetic diversity. At least twelve distinct clades, or ecotypes, of Prochlorococcus have been discovered so far, and follow ...
