The Fall And Winter Food Habits Of The Black Bear (Ursus Americanus) In The Great Dismal Swamp Of Virginia, Francis Leonard Daniel Oct 1978

The Fall And Winter Food Habits Of The Black Bear (Ursus Americanus) In The Great Dismal Swamp Of Virginia, Francis Leonard Daniel

Biological Sciences Theses & Dissertations

A study was conducted on the food habits of the black bear (Ursus americanus) in the Great Dismal Swamp of Virginia. A total of four stomachs and 42 scats were analyzed. Four samples were collected from September and October of 1975, and the remainder of the samples were collected from September 1976 to February 1977. The study was conducted to obtain information vital to the management of this species in the Great Dismal Swamp. Vitis spp. was the primary food item during the fall comprising 43% of the total diet, followed by fruits of Diospyros virginiana and Asimina triloba, each …

Experiments In Attempted Interspecific And Interpopulational Hybridzation Of Grass Shrimp Of The Genus Palaemonetes (Caridea Palaemonidae), Mark Andrew Boston Apr 1978

Experiments In Attempted Interspecific And Interpopulational Hybridzation Of Grass Shrimp Of The Genus Palaemonetes (Caridea Palaemonidae), Mark Andrew Boston

OES Theses and Dissertations

The present study investigates the interfertility of Palaemonetes populations, Interspecific crosses were attempted between representatives of sympatric :populations of P. pugio, P. vulgaris, and P. intermedius, Intraspecific crosses were undertaken between geographically separated :populations of P. pugio. Laboratory conditions of 25°c, 25°/oo, and 14.5 hour photoperiod per day were maintained for all breeding attempts, Under these conditions interspecific hybridization of Palaemonetes pugio and P. vulgaris was not feasible. P. intermedius could not be hybridized with P. pugio and P. vulgaris. At 40 days of age P. pugio juveniles were significantly larger than P. vulgaris juveniles of …


The Reproductive Cycle Of Microtus Ochrogaster In Eastern Kansas, Robert K. Rose, Michael S. Gaines Jan 1978

The Reproductive Cycle Of Microtus Ochrogaster In Eastern Kansas, Robert K. Rose, Michael S. Gaines

Biological Sciences Faculty Publications

About 800 Microtus ochrogaster were live—trapped at biweekly intervals from May 1971 through March 1973 in 3 grassland study areas in eastern Kansas, USA. Details of reproduction were determined by autopsy. Population density increased through the first winter, reached a peak in April 1972, then declined sharply during that summer and beyond. Body length, but not body mass, tended to be positively related to density. Both sexes matured at about the same weight; development was somewhat prolonged during the winter months, especially in the winter preceding the population peak. Pregnancy rates were high, approaching maximal iteroparity, throughout the study, with …


Zoogeography Of Antillean Bats, Robert J. Baker, Hugh H. Genoways Jan 1978

Zoogeography Of Antillean Bats, Robert J. Baker, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Analysis of the bat fauna of the Antillean Islands suggest that the most probable source of invasion of the islands by bats is by overwater dispersal. The bat fauna of ·the Greater Antilles is unique, a percentage of endemism on each island being over 50 percent except for the Virgin Islands which has 33 percent endemics.

The richest bat fauna in the Antilles is on Cuba (32 species) followed by Jamaica (23 species) then Hispaniola (17 species) and Puerto Rico (16 species). The number of species found on Cuba is probably the result of the island's proximity to Central and …

These studies were concerned with the development of methods to assist investigators of wildlife population research. Specifically they involve the description of (1) A device which enables an investigator to mark deer at medium range using specially modified darts fired by conventional tranquilizer rifles, (2) Construction of infrared viewers and light sources using surplus equipment and (3) Studies to develop a method of making permanent deer dental impressions under field conditions.


Population Dynamics Of Microtus Ochrogaster In Eastern Kansas, Michael S. Gaines, Robert K. Rose Jan 1976

Population Dynamics Of Microtus Ochrogaster In Eastern Kansas, Michael S. Gaines, Robert K. Rose

Biological Sciences Faculty Publications

Four eastern Kansas populations of the prairie vole, Microtus ochrogaster were live trapped from 1970—73 to gain insight into the population regulation of this species. All four populations exhibited a 2—yr cycle in numbers with peak densities generally occurring in June 1972. Peak densities were followed by a decline in numbers, a recovery, and a population crash in spring 1973. Reproductive parameters changed dramatically as density rose and fell. The summer breeding season in the crash year of 1973 was shortened by at least 3 mo. A reduction in breeding activity occurred during the summer of every year of the …


Effect Of Salinity On Glycogen Content In The Brine Shrimp, Artemia Salinas, Of Great Salt Lake, Christon H. Merkley Aug 1975

Effect Of Salinity On Glycogen Content In The Brine Shrimp, Artemia Salinas, Of Great Salt Lake, Christon H. Merkley

Undergraduate Honors Capstone Projects

The brine shrimp, Artemia salinas, is one of the few organisms to be found in the hostile environment of the Great Salt Lake. Salt concentrations in the lake are found to exceed those in the oceans. In such an environment, the utilization of energy, even after it has been procured, presents a problem. The life inhabiting the lake has developed extraordinary adaptations to this and similar problems.

Electron micrographs produced by Dr. Nabil Youssef of Utah State University have revealed that unusual quantities of glycogen can be found in the muscle of brine shrimp taken from the Great Salt Lake. …


Special Report On Controlling America's Pet Population Jan 1975

Special Report On Controlling America's Pet Population

Special Reports

HSUS estimates that public and private animal control programs cost the nation as much as $500 million a year. Much of this expense is required for the feeding and care of unwanted animals during the 5 to 10 days they are held for adoption, killing the 80% that are not adopted or redeemed, and disposing of the carcasses. The result is both an unconscionable waste of life and a needless drain on public and private money.

A large part of the blame for people undertaking pet ownership without having made a total commitment to the animal lies with the pet …
