Analysis Of Four Common Play Patterns In Juvenile Thirteen-Lined Ground Squirrels (Spermophilus Tridecemlineatus), Mary Melville
Analysis Of Four Common Play Patterns In Juvenile Thirteen-Lined Ground Squirrels (Spermophilus Tridecemlineatus), Mary Melville
Field Station Bulletins
Young mammals spend a considerable amount of time engaged in activities which are called "play". The ethological literature contains much controversy concerning the definition and adaptive significance of play. Fagen (1974) characterizes playas active, oriented behavior with a highly variable structure, which apparently lacks immediate purpose, and which is often accompanied by specific signal patterns. He also notes that in playful behavior the adult sequences of behavior break down. Behavioral components such as threats, grooming and sexual posturing are performed in novel and rapidly changing sequences that would be nonadaptive in the serious contexts of adult life. Play in young …
The Effect Of Human Disturbance On Vegetation At The Wehr Nature Center In Whitnall Park, Mariette M. Nowak
The Effect Of Human Disturbance On Vegetation At The Wehr Nature Center In Whitnall Park, Mariette M. Nowak
Field Station Bulletins
During 1975 and 1976, I studied (Nowak, 1976) two woodlands at the Wehr Nature Center in WhitnaLl Park, Milwaukee County (Figure 1). My purpose was to document the vegetational changes brought about by human disturbance. The Wehr Woods, adjacent to the Wehr Nature Center Building, had been lumbered and grazed; while the woods along College Avenue is subjected to seasonal flooding, a result of road construction which had altered the drainage pattern. In each woodland, a disturbed portion was compared with an adjacent, relatively undisturbed area. The heavily lumbered and grazed portion of the Wehr woods will be referred to …

A Study Of A Population Of The Slender Glass Lizard In Waushara Co., Wisconsin, Thomas A. Pleyte
Field Station Bulletins
The slender glass lizard (Ophisaurus attenuatus), a limbless member of the family Anguinidae, is one of the few lizards found in the state of Wisconsin. Records indicate that it is found locally in several sandy areas in the southern half of the state but little was known about its abundance in any of these areas before the present study was conducted in 1973 and 1974.

The International Congress of Scientists on Human Environment was convened under the combined auspices of the Science Council of Japan; the United Nations Environmental Program (UNEP), Man and the Biosphere (MAB), the Scientists' Committee on Problems of the Environment (SCOPE) and the Special Committee on the Environment of the International Social Science Council (ISSC). The 519 participants in the Congress included 95 representing 27 countries in addition to Japan. The Congress was organized by General Secretary, Prof. Y. Fukushima for the Science Council of Japan, an elected group representing 200,000 scientists. The Congress built upon the 1970 Tokyo Symposium on …
