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

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.

Terrestrial Ecology Of The Dickey-Lincoln School Lakes Project, Corps Of Engineers, New England Division, Environmental Research & Technology, Inc

Dickey-Lincoln School Lakes Project

This introduction of the St. John River watershed is situated in a transitional zone between the Boreal Forest Formation and the Eastern Deciduous Forest Formation. Second-growth forests representative of these two ecosystems cover extensive areas of the project site. The boreal forest forms a broad transcontinental belt in northern North America and Eurasia, with southern montane extensions. This northern forest is characterized by evergreen, coniferous trees, predominately spruce-fir The eastern deciduous forest, composed of broad-leaved hardwoods, extends throughout the eastern United States except Florida (Dasmann, 1968; Oosting, 1956).

Effects Of Six Insecticides On Emergence Of Some Parasites And Predators From Southern Pine Beetle Infested Trees, Jack E. Coster, I. R. Ragenovich

Faculty Publications

Six insecticides (lindane, phosmet, diazinon, acephate, propoxur, and carbaryl) were tested to determine effects on predators and parasites associated with southern pine beetle, Dendroctonus frontalis Zimmerman, in eastern Texas. Eleven species of parasites and predators emerged from insecticide-treated pine bolts. The most prevalent species was Coeloides pissodis followed by Medetera lJistriata, Roptrocerus xylophagorum, Corticeus glaber, and Thanasimus dulJius. In terms of emergence from treated pines, only diazinon significantly reduced the total number of associated insects. They were 65% fewer in number following diazinon treatment. The insecticides differed in their effects on the 11 associates. C. glaber, C. pissodis, M. lJistriata, …

Endoparasitic Nematodes Of Ips Bark Beetles In Eastern Texas, Jack E. Coster, William Hoffard

Faculty Publications

East Texas Ips species contained 4 specific internal nematodes; I. avulsus (Eichhoff) were infected with Parasitylenchus avulsi Massey, I. grandicollis (Eichhoff) with Contortylenchus grandicolli (Massey) Rlihm, and I. calligraphus (Germar) with Contortylenchus elongatus (Massey) Nickle and Parasitaphelenchus sp. In all 3 bark beetles, infection peaked in July and August when 50-58% of adults from naturally attacked pine trees contained nematodes. Infection levels declined to 20-30% during January and February. Infected I. grandicollis and I. avulsus adults appeared lighter in color than noninfected adults. Nematode infection apparently delayed emergence of both sexes of I. grandicollis and females of I. avulsus. In …

Aspen Mortality In Rocky Mountain Campgrounds, Thomas E. Hinds

Aspen Bibliography

Aspens die from canker disease infections as a result of mechanical injuries to the live bark inflicted by thoughtless campers. Dead trees usually are cut to reduce camper hazard. Aspen loss is related to campground age. A desirable aspen-type camp unit can be degraded to a treeless site of grass, forbs, and shrubs within 10 to 20 years. The management of aspen campgrounds must be altered if the resource is to be maintained.

Aspen Bibliography

Following pioneering work in northern Idaho and eastern Washington by Daubenmire 1952, 1968, and later in Montana, Idaho, Wyoming and Utah by Pfister et al., 1974, Steele et al., 1974, 1975, Cooper 1975, Reed 1969, Ream 1964, and Pfister 1972, work was begun to finish identifying and naming the forest habitat types of Utah. Preliminary work had been done by Pfister (1972) on the subalpine fir and engelmann spruce series. This current work covers all forest land in Utah and adjacent southern Idaho including that covered by Pfister.

Bird Populations Of Aspen Forests In Western North America, J.A. Douglas Flack

Aspen Bibliography

The patterning of populations of plants and animals is probably the result of selection over time of organisms according to their individual physiological tolerances, behavioral adaptations to an environmental complex, and geographical availability (Gleason 1926).

Understory Production Not Predictable From Aspen Basal Area Or Density, K.E. Severson, J.J. Kranz

Aspen Bibliography

Analysis of effects of aspen basal area and density on production of understory vegetation revealed no useful predictive relationships using the model log Y = a + bX. However, as the proportion of ponderosa pine basal area increased in aspen-pine stands, understory production declined in a predictable manner. Root biomass, total biomass, and/or growth rate of aspen may be more closely related to understory production than measures of aspen overstory.

Type Variability And Succession In Rocky Mountain Aspen, Walter F. Mueggler

Aspen Bibliography

Most of the 6 million acres of aspen lands in the West occur in the Central Rocky Mountains. The ability of western aspen to occupy a wide diversity of sites, the great genetic diversity among clones, and the role of aspen as both a dominant successional and stable species severely complicate management. Such ecological and genetic diversity results in considerable variability in both resource production and potential response to management. Progress in classifying the ecological variability of aspen lands is slow; useful partitioning of genetic diversity is nil.
