Abstract
This year saw a wide range of research and teaching at the Station
and consequently heavy demands on the facilities. Eight projects were
undertaken, four continued froin the previous year and four new studies
were initiated. The first group included investigations of habitat and
food use by white-tailed deer; the relationship between evapotranspiration
in PhJr..a..gmUe6 and water table fluctuations; the ecology of the hardand
soft-stem bulrush (Sc£npU6 aQutuh and S. validU6) and the effect of
the Assiniboine Diversion on the southern end of Lake Manitoba. New
research projects covered an equally wide range of topics, namely:
life cycle studies of two nematodes (Rhabdi~ sp.) in frogs and toads;
a survey of soil and water fungi in the marsh; the effect of fire on
P~agmUe6 and the mapping of lakeshore vegetation.
It is a pleasure to acknowledge the continued financial support from
the Department of ' Mines, Resources and Environmental Management, the
National Research Council, Ducks Unlimited, Canadian Industries Limited
and the University of Manitoba. In addition, this year two of our summer
assistants were supported by the Opportunity for Youth program.
We were pleased to welcome two other researchers: Mrs. C. H. Nelson,
who spent three days continuing her work on downy ducklings, and Dr. B.
J. Richardson, who collected blood samples from redbacked voles and deer
mice for enzyme studies.
Four projects were concluded in 1971. T. O. Acere was awarded an
M.Sc. for his stickleback population study, while D. Bernard and D. Brown
should complete their M.Sc. theses in the spring of 1972. Dr. J. Wright's
ecological study of benthic fauna has yielded a wealth of information,
particularly with respect to the effects of freezing on invertebrates.
His publication should be in press in the near future. The importance of
winter research is also emerging from the white-tailed deer studies of
Dr. E. Kucera. Our long-term objective is to obtain an understanding of
the dynamics of the marsh ecosystem, and each project brings it a little
nearer.
The Station was used for 334 resident-weeks. The following staff,
graduate students and techni ci ans were present for a 11 or part of the
summer:
