Demography, Movements, Activity, Habitat Utilization And Marking Behavior Of A Bobcat (Lynx Rufus) Population In South-Central Florida, Douglas A. Wassmer

USF Tampa Graduate Theses and Dissertations

Eighteen (6 male and 7 female adults, 5 juveniles) radio-collared bobcats (Lynx rufus) were monitored on the Archbold Biofogical Station and vicinity during 1979-1982. Mean density was 0.06 males, 0.11 females, and 0.19 juveniles per 100 ha. Mean sex and age ratios were 0.6 adult males per adult female and 1.22 juveniles per adult. Breeding occurred from September to March. Mean size of 13 mobile litters was 2.5 (range 1-4). Nine (50%) of 18 collared cats died. Nine additional individuals were found dead or reported killed. Known causes of 16 deaths were: road-killed 8, feline panleukopenia or notoedric …

A Review Of The Adults And Larvae Of The Genus Pycnopsyche (Trichoptera: Limnephilidae) With Revision Of The Pycnopsyche Scabripennis (Rambur) And Pycnopsyche Lepida (Hagen) Complexes, John A. Wojtowicz

Doctoral Dissertations

The adults and larvae of the genus Pycnopsyche are reviewed. Nineteen species are recognized for the genus. The males and females of all species are described and illustrated. All species accounts include description, diagnosis, type locality, distribution, variation, notes and material examined sections. The P. scabripennis complex is revised, and three distinct species are recognized (P. scabripennis s.s., P. antica, and P. conspersa). The P. lepida group (P. lepida, P. indiana, P. subfasciata, and P. virginica) is also revised with all species remaining recognized; however, P. virginica is removed from the complex. …

Food Habits And Ecology Of Beavers In Southeastern Virginia, John Lennox Echternach Jr.

Biological Sciences Theses & Dissertations

The food habits and ecology of three beaver colonies in James County, Virginia were studied. Vegetation surrounding the colonies was characterized as southern mixed hardwood forest or lowland swamp forest. Stream flow values ranged from 0.013 to 0.369 m³/sec. Water depth ranged from 0.5 60 4.0 m. Caloric value of 13 heavily used woody species ranged from 3305 to 6204 cal/g. Considerable seasonal variation was noted in most species with the lowest caloric values noted in summer. No relationship was found between caloric value and frequency of use. Fresh cutting was monitored on a weekly basis and a …

Lotic Dragonfly (Anisoptera: Odonata) Nymphs Of The Southeastern United States: Identification, Distribution And Historical Biogeography, Jerry A. Louton

Doctoral Dissertations

An identification guide to the southeastern United States lotic dragonfly nymphs is constructed. Descriptions, figures, keys, verification tables, and distribution maps are provided to facilitate identification of families, genera, and species. Information developed in the study of nymphs is utilized to evaluate arrangements of taxa that have been traditionally based solely on adult characters. Traditional arrangements are supported except (1) subgenera of the genus Gomphus s.1. are highly distinctive in the nymphal stage and should be elevated to generic rank and (2) two species, Gomphurus consanguis and G. rogersi are improperly placed and as a group deserve generic rank.

Foods And Feeding Of The Redfin Shiner (Notropis Umbratilis) In Coles County, Illinois, Karen Denise High

Masters Theses

Foods and diel feeding activities of the redfin shiner, Notropis umbratilis, were studied in Coles County, Illinois in September, 1981, and monthly from April through September, 1982. A total of 200 stomachs with food were examined. Diptera adults and larvae were the most frequently occurring food item (83%), and also occurred in the highest volume (49%). Coleoptera were the second most frequently occurring item (23%), and accounted for the second largest volume (11%). Larger fish consumed a wider variety of food items. Changes in foods with season were also noted.

Feeding activity on the 24-25 July was greatest in …

Spatiotemporal Distribution And Abundance Of Fry Of Bluegill (Lepomis Macrochirus) And Redear Sunfish (Lepomis Microlophus) With Special Reference To The Effect Of Turbidity On Reproduction, William F. Dimond

Masters Theses

Plexiglass fry traps were used to investigate the abundance and spatiotemporal distribution of bluegill and redear sunfish fry in Ringneck Pond, a small pond in Central Illinois. High spring turbidity delayed spawning of both species. Bluegill fry were more abundant than redear sunfish fry. Small bluegill fry (14 mm to 20 mm TL) inhabited open water more commonly than large bluegill fry (20.5 mm to 26.5 mm TL) but densities of both size groups were highest in a sheltered bay at the north end of the pond. Bluegill fry avoided the surface in open water. Catch rates of bluegill and …
