Insect Parasitoids of High Arctic Woolly-bear Caterpillars
Principal Investigator: Morewood, Dean
Licenced Year(s): 1994 1993
Summary: In order to study parasitoids of woolly-bear caterpillars, surveys will be conducted to assess the population of caterpillars, caterpillars will be dissected to collect immature parasitoids and as information about the parasitoids' life cycle as they develop within the caterpillars, and caterpillars will be collected to watch the development of the parasitoids within living `hosts' and to carry ou...


A Northern Forest Ecosystem Simulation Model of Early Post-Fire Tree Seedling Establishment, Growth and Competition
Principal Investigator: Gal, Ruth Ann
Licenced Year(s): 1993 1992
Summary: The researcher and her team will glean physiological rates and relationships for tree growth from the literature and substitute the data into a functional model, which will be calibrated against intensive sampling within WBNP over dry, mesic and wet landscapes....


Environmental Physiology of Marine Invertebrates
Principal Investigator: Graham, Mark S
Licenced Year(s): 1992
Summary: The researcher and his team will use several species of planktonic and benthic invertebrates from Lancaster Sound region to evaluate the metabolic cost of making a living in the Arctic. Oxygen consumption techniques will be used as a metabolic indicy. Trophic status of specimens will be evaluated later by stable isotope analysis....


Geographic Distribution, Physiological Adaptations, Systematics and Ecology of Stream Macroalgae in North America
Principal Investigator: Sheath, Robert
Licenced Year(s): 1994 1992
Summary: The researcher and his team will survey streams for macroscopic algae, and relate their distribution to various physical and chemical characteristics, biomes and drainage basins. They will also set up a seasonal study of the physiological adaptations of macroalgae to the harsh conditions of tundra streams. As well, a widespread seaweed will be collected for comparison with other populations to d...


Polar Ecology Field Research
Principal Investigator: Curtis, Mark A.
Licenced Year(s): 1992 1989
Summary: The research scientists and graduate students involved are primarily interested in three topics in the aquatic ecosystems of the Igloolik region: (1) the species compostion of marine phytoplankton; (2) the cold adaptation physiology of polar cod; (3) the parasites of arctic char....


Migration, Ecophysiology and Energetics of Shorebirds at Alert, Ellesmere Island
Principal Investigator: Morrison, R.I.G.
Licenced Year(s): 1992 1991 1990
Summary: Work by Dr. Morrison at Alert in the mid 1970's established the Knots and Turnstones breeding on northern Ellesmere Island migrate to wintering grounds on the European seaboard. Most migrate via staging areas in Iceland, though some of the population reaches Ellesmere via Norway. The internationally coordinated research program carried out over the last six years to study the migration, ecophysiol...


Sleep Performance Under Conditions of Extreme Cold and Physical Exhaustion: Weber-Malakhov Trial Expedition
Principal Investigator: Newman, Janice
Licenced Year(s): 1991
Summary: The Researcher will train 4 polar trekkers on performance tests and how to apply an electrocap (electrodes housed in a mesh cap). The participants will apply these techniques as they engage in a practice trek around the Iqaluit area....


The Prediction of Physique from skeletal measurements and ratios.
Principal Investigator: Porter, Alan M.W.
Licenced Year(s): 1991
Summary: This researcher will measure the stature, sitting height, weight and various long bones of Inuit volunteers. A metal tape measurer and anthropological calipers will be used during this approximate 15 minute process....


Biology and Cold Hardiness of Aphids in the Canadian Arctic
Principal Investigator: Ring, Richard A.
Licenced Year(s): 1993 1992 1990 1987
Summary: Professor Ring will continue an ongoing study on arctic insect cold-tolerance....


Breeding Biology of the Harris' Sparrow and White-crowned Sparrows in the Thelon Game Sanctuary, N.W.T.
Principal Investigator: Norment, Christopher
Licenced Year(s): 1991 1990
Summary: Mr. Norment is studying the breeding biology of the Harris' Sparrow and White-crowned Sparrow. He will be collecting data on any physical (such as weather, food supply, nest-site, predators) or genetic (such as number of eggs, breeding cycle, condition of females) factors....
