Changes in plant communities from subarctic forest to tundra
Principal Investigator: Henry, Gregory H.R.
Licensed Year(s): 1995 1994 1993 1991
Summary: This study continues from the research conducted in 1991 where we examined the plant community and assessed plant distribution as the subarctic forest changes to tundra. We are interested in how the smaller plant species are influenced by changes in the number of trees that are nearby as well as changes in climate. Permanent plots will be established in order to monitor any changes in the plant ...

Effects of predicted climate change on high arctic plants
Principal Investigator: Henry, Gregory H.R.
Licensed Year(s): 1994 1993 1992
Summary: As part of a long-term study, we will continue to monitor the field experiments set up at Alexandra Fiord on Ellesmere Island which examine the effects of climate warming on high arctic plants. Small enclosures have been placed on top of the plants in order that the growing conditions such as temperature and moisture can be altered and their influences on the plants examined. This study is part ...

Eco-physiology of Several Pan-Arctic Plant Species
Principal Investigator: Henry, Gregory H.R.
Licensed Year(s): 1988
Summary: Some Arctic plants are found in almost every type of habitat, from wet meadows to dry gravel areas. Dr. Henry, Dr. Zilder and several students are looking at these plants to see how that is possible....
