Résumé:
Zooplankton will be collected from lakes and ponds located along a transect between Paulatuk and Shingle Point (Yukon). The specimens that are collected will be identified according to species type and genetic analyses will be performed to determine what species are interbreeding to produce hybrid organisms. Knowledge about zooplankton is important as many organisms (such as fish) depend on thes...

Résumé:
Organochlorine contaminants can be carried to the arctic in the atmosphere. I will be measuring the amount of these contaminants in zooplankton to determine the effects and range of organochlorines in the arctic ecosystem. The information that I collect will be useful in determining what types of organochlorines are most common in zooplankton as well as providing a means to estimate the levels o...

Résumé:
The researcher and his team will measure the amount of genetic diversity in arctic zooplankton, determine distributions and numbers of species in arctic lakes and ascertain factors limiting species distributions in the arctic....

1990 Résumé:
The Researcher will continue to study the distribution of phytoplankton and zooplankton in the Barrow Strait area. The herbivourous plankton species which feed on the marine algae and phytoplankton is the first step in the arctic food chain. It is the herbivorous plankton which is the source of food for other animals which ultimately provides food for all other higher arctic animals....
