Abstract:
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.

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. Phillips is
entitled liThe Rel ationship between Evapotranspiration by Phnagmiteb c.ommu.tU.-6
Trin.and Water Table Fluctuations in Delta Marsh, Manitoba". Glen Girman
was awarded an M.Sc., his thesis being on liThe Effects of a Number of
Herbicides upon Photosynthesis and Heterotrophy of Naturally occurring Algal
and Bacteral Communities in Delta Marsh,Manitoba" and Susan Eddy received an
M.Sc. for her thesis on "Population of the Leopard Frog Ran.a p.<.p.<.en..6 p.<.p.<.en..6
