INHS - Bulletins 1940s

Bulletins from the 1940s

The Illinois Natural History Survey Bulletin has been published continuously since 1876. This peer-reviewed journal reports on significant research findings by INHS scientists and others in the natural sciences. It is our premier scientific serial and has a worldwide distribution. Professional researchers and graduate students contribute to and utilize this series.

INHS B25-02: Effect of Permanent Flooding in a River-Bottom Timber Area

Author: Yeager, L.E.
1949; 32 pages.

The objective of the study on which the present report is based was to determine the rate of flooding mortality in various Mississippi River valley tree species and the rate and effect of tree fall; in the course of the study, brief consideration was given to plant and animal succession following the death of timber stands. The report covers principally the period beginning in September, 1939, and ending in October, 1946.


INHS B24-03: The Bass-Bluegill Combination in a Small Artifical Lake

Author: Bennett, G.W.
1948; 35 pages.

The investigation of Fork Lake was originally planned to study the effect of heavy cropping upon the combination of largemouth bass and bluegills in a small artificial lake or pond. The results obtained were influenced by the unexpected spread of Potamogeton foliosus in this pond, and a proposed final fish census was rendered impossible by a washout of the dam in 1942.


INHS B24-01: The Mosquitoes of Illinois (Diptera, Culicidae)

Author: Ross, H.H.
1947; 96 pages.

The object of this paper is to provide means for making mosquito control programs more effective, first by furnishing illustrated keys and descriptions for the identification of mosquito species that occur in Illinois and states similar in climate, and second by summarizing information regarding the distribution, biology, and habitat preferences of the species.

      • Survey of the Illinois Fur Resource

            Author: Brown, L.G. and L.E. Yeager
            1943; 70 pages.

      • Illinois Furbearer Distribution and Income

            Author: Mohr, C.O.
            1943;337 pages

Distributional information information and annual catch data derived from fur-takers' monthly reports are at hand for most of the trapping seasons beginning with 1929-30 and ending with 1939-40 and are here recorded, along with records of the number of licensed fur-takers and estimates of their catch. After being compared with findings of the oral survey, raw data reports were revised in such a way as to show better than heretofore how the value of the fur catch has stood from year to year. Data for the seasons of 1931-32, 1932-33 and 1933-34 were not available to the writer, and these seasons therefore could not be considered in this study.

      • The Prairie Chicken in Illinois

            Author: Yeatter, R.E.
            1943; 40 pages.

The 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 Illinois.

      • Preferential Rating of Duck food Plants

            Authors: Bellrose, F.C., Jr. and H.G. Anderson
            1943; 17 pages

Employing data based upon the occurrence of the plants, as well as upon consumption by ducks of the plant parts, the writers have attempted to present and accurate appraisal of the value of certain plants of the Illinois River valley as waterfowl food sources. By dividing the per cent of use made by ducks by the per cent of abundance of the important aquatic and moist-soil plants occurring in the valley, it was possible to secure and index figure of value for each of these species. We believe the figures obtained to be far more reliable indicators of value as waterfowl food sources than are data derived only from plant parts taken by the birds. Numerous factors, such as seed production and accessibility, influence sources of supply that vary with the habitat and year. Taking cognizance of these variables (as discussed under each species) makes it seem advisable to judge the value of each species on the figures for no one year, but to use the index value for the year or years that seem most typical. This procedure places 25 plants or groups in the following descending order of value as food for ducks in the Illinois River valley, 1938, 1939 and 1940. Tables 3, 4, 5 and 6 give comparative values for species and years.


INHS B22-01: The Plant Bugs, or Miridae, of Illinois

Author: Knight. H.H.
1941; 234 pages.

The list of Miridae of Illinois now stands at 330 species. It is apparent, however, that species known from neighboring states will eventually be found in Illinois. Furthermore, in the study of Illinois species, it was found that many records of these species were a great distance from any other previously known records. Hence, it was thought advisable to include in the keys other species and varieties known from the entire general region in which Illinois is situated. One hundred ten extralimital species were, therefore, included, bringing the total number treated in this report to 440 species. It seems highly probable that from two-thirds to three-fourths of these extralimital species will eventually be found in this state, which would bring the list of Illinois Miridae to about 400 species.
