- ItemOpen AccessThe University of Manitoba Field Station Delta Marsh 1973 Annual Report Number 8(University of Manitoba, 1973) Shay, J.M.Introduction The University Field Station has taken on a dual role by maintaining both an active research program and providing educational services to University students, high schools and the general public. If natural resources like the Delta Marsh are to be maintained and managed to yield their maximum benefits, basic ecological information must be gathered and its significance disseminated as widely as possible. By combining research and education, the Station endeavors to meet these objectives. During 1973 the Station increased its already active program in research and teaching. For example, it was used for 454 resident weeks, an increase of 11% over 1972. The participants included: Staff Dr. J. Gee (Acting Director) Dr. J. M. Shay (Director) J. Evans (Botany) Dr. ' G. Robinson (Botany) Dr. C. Tudorancea (Zoology) Assistants M. Danielson M. Knight W. Lysack L. Nostedt M. Rayner P. Simonson H. Smart T. Wallis Graduate Students S. Bates (Zoology) G.

Mulder (Housekeeper) I. Garnham (Cook) Our facilities were used for short periods by Dr. M. Aleksiuk (Zoology), Dr. T. Booth (Biology Teaching Unit), Dr. R. Green, R. Pauls and T. Stewart (Zoology) in relation to their research. We were pleased to welcome Dr. C. Tudorancea (Faculty of Biology, University of Bucharest) who joined the staff as a Post-doctoral Fellow in April to study benthic fauna in Lake Manitoba. His investigations will continue until September 1974.

- ItemOpen AccessThe University of Manitoba Field Station Delta Marsh 1975 Annual Report Number 10(University of Manitoba, 1975) Shay, J.M.Introduction Over the years there has been a steady increase in use of the Station. In 1969, for example, we reported 265 resident weeks of occupation; in 1975 this had risen to 555 with a daily average of 15 from April until midSeptember, while use continued throughout the year for short courses and ongoing research. Participants included faculty,graduate students, those taking regular University and Summer Session courses, Continuing Education programs and High School ecology field trips. One of the advantages of the Field Station is that it brings together people with a diversity of backgrounds and interests. Staff Dr. J. M. Shay (Director) Dr. M. Aleksiuk (Zoology) Dr. T.

Mulder (Manager) N. Rodd (Maintenance Asst.) Research Fourteen research projects were in progress during 1975. In their second or final year were the studies of muskrat thermodynamics; striped skunk winter ecology; post-breeding dispersal of ring-billed gulls; epiphytes on aquatic macrophytes :; Chen.opoc.Uum ecology and grazer-aquatic plant interrelationships. New projects included studies of the breeding biology, and feeding ecology of yellow warblers; interaction of the endocrine system and parasite fauna of the red-winged blackbird; copepod parasites of saugers and walleyes; the ecology of the bullhead, and temporal succession in beach fungi. Two long term studies: ecology and productivity in Phnagmiteb and protozoan and he l minth parasites of frogs and toads were continued, these are outlined in the University Field Station Annual Report No.9, 1974. Summaries and progress .reports for the projects, except those on fungi and Phnagmiteb, are included l ater in this Report . Our warm congratulations to three graduate students who have successfu l ly completed their studies. The Ph . D. thesis of Floyd S.

- ItemOpen AccessDelta Marsh Field Station Annual Report Number 7,1972(University of Manitoba, 1972) Gee, Dr J.HDuring the past year the University Field Station was used actively for research and teaching. To meet increased demands in both these areas, facilities were improved for greater accommodation. Mr. Barry Wallis joined the staff in summer as Executive Assistant to the Director and his presence has increased the efficiency of the operation of the Station. Research The long-term objective of our research program is to provide a better understanding of the dynamics of the marsh ecosystem. Ten research projects were carried out; of these six were continued from last year and four new studies were initiated. Dr. Emil Kucera completed his study on the population ecology of white-tailed deer and a report has been prepared providing much-needed information necessary for the management of deer in a marshland environment. Don Bernard and Marty Quaye were awarded M.Sc. degrees for their respective studies on shiners in Lake Manitoba and nematode parasites in frogs and toads. Both Sandy Macaulay and Floyd Phillips, working on Ph.D. programs, have finished their field studies at the Station and expect to complete their projects in 1973. Research projects received support from the Department of Mines, Resources and Environmental Management (Research Branch), National Research Council of Canada, Ducks Unlimited, Canadian Industries Limited and the University of Manitoba. Staff and Utilization of Facilities The Station was used for 409 resident weeks and 3,747 meals were served. The following staff, students and summer assistants were present for all or part of the year: Faculty Dr. J. M. Shay, Director (to July) Dr. J. H. Gee, Acting Director (from July) Dr. K. W. Stewart, Department of Zoology Dr. E. Kucera, University Field Station (January-May) Facul ty (continued) Dr . L. Mottus , University Field St ation (June -October) Graduate Students S.

Foley, Summer Assistant G. Connor, Summer Assistant Permanent Staff B. Wallis , Executive Assistant B. A. Huyghe , Secretary N. Mulder , Manager G. Mulder , Housekeeper I. Garnham , Cook Informal seminars were given by staff and graduate students throughout the summer. The Field Station is now available for year-round use and I feel it has a great potential for research and teaching in winter. In January and February 1973 Dr . E. E. Moodie from the University of Winnipeg brought out his ecology class for a two-day field course and I took the third year ecology class out over a three-day period. In addition, there was an Extension Division course on Human Survival given over three days . During these two months alone , the Station was used for 57 resident weeks . There is a strong demand for education in winter ecology and much-needed research at this time of year can be carried out from the Field Station . Its use in these areas should be actively promoted .
- ItemOpen AccessThe University of Manitoba Field Station Delta Marsh 1971 Annual Report Number 6(University of Manitoba (DELTA MARSH), 1971) Shay, J.M.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: Faculty Dr. J. Gee (Zoology) Dr. E. Kucera (University Field Station) Dr. J. M.
