The Prairie Chicken in Illinois
Get PDFThe present report summarizes a study
of the biology and management of the
greater prairie chicken in Illinois, a study
begun in 1935 by members of the Section
of Game Research and Management of
the Illinois Natural History Survey. The
summers of 1935 and 1936 were spent
in full-time field work in southeastern
Illinois. Since that time, supplemental
studies of prairie chicken habits, requirements
and distribution have been continued
in various parts of the state. Annually
since 1935, spring and fall censuses
have been made on 4 square miles of
prairie chicken range in Jasper County
used as a study area. Preliminary parasite
and disease studies conducted by
Leigh (1940) were published in another volume of the Survey Bulletin. The present
report includes data on early distribution,
present range, life history, populations,
mortality causes, food habits and
management of the prairie chicken in

Tularemia, Weather, and Rabbit Populations
Get PDFTULAREMIA, a disease of rabbits
and hares (lagomorphs), rodents,
and several other animals, is
transmissible to man. In the period 1926-
1940. Illinois had more than 3,000 reported
cases of human tularemia, about
twice as many as any of the other states.
The great majority of these Illinois cases
were traceable to contact with cottontail
rabbits. This paper deals with the relation of
human tularemia in different parts of the
state and in different years to weather, to
the abundance of rabbits, and to some other
aspects of its epidemiology. In analyzing
the information on tularemia in Illinois, the writers have made an effort to determine the methods of management which
would permit Illinois hunters to enjoy the
sport of rabbit hunting without undue risk
of infection.published or submitted for publicationis peer reviewe
