Further Studies on Deciduous Forest Animal Communities

The Tomocerinae (Collembola) in Old Field Stands of North Carolina

“…Tomocerus and Entomobrya were the most common genera in this ecological niche with populations of both genera higher during the moister part of the year (early fall). In an elm-maple forest in Illinois investigated by Blake ( 1931), T. fiavescens was present from early March to mid-June and underwent fluctuations in keeping with moisture and temperature differences, decreasing as temperatures increased and moisture values declined in the litter stratum. Bohnsack ( 1954), in a study of the forest floor arthropods of an oak-hickory woodland in southern Michigan, found that T. fiavescens and T. lamelliferus exhibited greatest density in April, May, June and September.…”

The Bird Population of an Elm‐Maple Forest with Special Reference to Aspection, Territorialism, and Coactions

“…In 1925-1926, Smith (Davidson) (1928 studied the climax and developmental stages of the forest. Blake (1931) made a comparison of the 1924-1925 animal communities with those described by Smith (Davidson) and Weese. In the meantime Smith-Davidson (1930) reported on the tree-layer society and, later, on the effect of seasonal variation of weather upon the population of animals in the succession of a deciduous forest. Rice (1939) and Kanatzar (1935) studied the invertebrate population for the periods -1936, respectively.…”
