Trilobite biostratigraphy of Rockslide Formation (Middle Cambrian)
Principal Investigator: Pratt, Brian R.
Licenced Year(s): 2012 2002 2000 1998
Summary: Outcrops in the Mackenzie Mountains preserve an almost uninterrupted sequence of strata of Cambrian age. This study aims to collect in bed-by-bed detail the trilobite fossils from the Rockslide Formation, the Middle Cambrian portion of the sequence. The taxonomy and biostratigraphy of these fossils will generate a refined time scale for this part of the geologic column, some half a billion years o...


Genetic Diversity in the Biota of Arctic Lakes
Principal Investigator: Hebert, Paul
Licenced Year(s): 1997
Summary: Our research will involve the survey of zooplankton communities in lakes and ponds of the Mackenzie Delta area (Inuvialuit private lands). Samples will be collected by either wading in ponds or by towing at net behind a float equipped helicopter. Samples will be frozen in liquid nitrogen, and subsequently examined for genetic variation. Our work aims to establish the species diversity of zoopla...


Ecology and population genetics of freshwater invertebrates of the Arctic.
Principal Investigator: Boileau, Marc G.
Licenced Year(s): 1988 1987 1986
Summary: To investigate the ecology and population genetics of crustacean zooplankton. To study the genetic diversity of the major species of copepods and their dispersal since deglaciation. To clarify the taxonomy and improve distribution records....


Studies on genetic diversity in freshwater invertebrates and lake trout, at a high arctic site.
Principal Investigator: Hebert, Paul D.N.
Licenced Year(s): 1987
Summary: To continue work on the genetics and ecology of arctic freshwater organisms during 1987. To assess the levels of genetic diversity in ostracode populations, distributional patterns of the dominant ostracodes, while supplementary studies will examine the ecology of ostracode crustaceans and turbellarian flatworms. In addition small samples (5-10 individuals)of Salvelinus namaycush will be obtaine...


Continuation of the research and fieldwork on Ellesmere and Banks Island of a biostratigraphic program on the marine fauna from the Eureka Sound Formation.
Principal Investigator: Zinsmeister, William J.
Licenced Year(s): 1988 1987
Summary: To determine: (1) the composition of the marine invertebrate faunas of the Eureka Sound Formation; (2) the stratigraphic distribution of individual taxa so that a biostratigraphic zonation could be established; (3) the biogeographic relationships of the faunas of the Eureka Sound Formation with temporal faunas of the North Atlantic....
