Fisheries Report No 34 - The Status Of The Salt-Water Crocodile In The Glenelg, Prince Regent And Ord River Systems, Kimberley, Western Australia, A. A. Burbidge, H. Messel Jan 1979

Fisheries Report No 34 - The Status Of The Salt-Water Crocodile In The Glenelg, Prince Regent And Ord River Systems, Kimberley, Western Australia, A. A. Burbidge, H. Messel

Fisheries Research Reports

Counts were made of Salt-water Crocodiles (Crocodylus porosus) in the estuarine portions of the Glenelg, Prince Regent and Ord River systems of the Kimberley Division, Western Australia. During the survey 581 crocodiles were seen, including 143 hatchlings. The number of non-hatchling crocodiles in present the Glenelg system is estimated to be 200 to 259, in the Prince Regent 190 to 246 and in the Ord 235 to 306 (95% confidence limits).

The number of non-hatchling crocodiles present in the six Kimberley river systems now counted is estimated to be between 957 and 1243 (95% confidence limits) and we believe that …


Status Of The Red-Cockaded Woodpecker At The Felsenthal National Wildlife Refuge In Arkansas, Douglas A. James, Fred L. Burnside Jr. Jan 1979

Status Of The Red-Cockaded Woodpecker At The Felsenthal National Wildlife Refuge In Arkansas, Douglas A. James, Fred L. Burnside Jr.

Journal of the Arkansas Academy of Science

The Red-cockaded Woodpecker is an endangered species that is endemic to mature pine forests of the southeastern United States. In Arkansas it presently occurs only in pinelands of the Ouachita Province and Gulf Coastal Plain. Cavity trees for nesting and roosting must be mature pines diseased with red-heart fungus. Due to recent forestry practices mature pine stands are disappearing thus reducing numbers of needed cavity trees. The Felsenthal National Wildlife Refuge in southeastern Arkansas contains high densities of Red-cockaded Woodpeckers and because of favorable management priorities there the survival of the woodpecker seems assured. Populations of the species in other …


Niobrara-Missouri River Fishery Investigations, Larry W. Hesse, Gene Zeurlein, Roger Vancil, Leonard Koziol, Brad Newcomb, Leigh Ann Retelsdorf Jan 1979

Niobrara-Missouri River Fishery Investigations, Larry W. Hesse, Gene Zeurlein, Roger Vancil, Leonard Koziol, Brad Newcomb, Leigh Ann Retelsdorf

Nebraska Game and Parks Commission: Publications

The Niobrara River heads in the table lands of eastern Wyoming and flows 786 kilometers (km) eastward across Nebraska joining the Missouri River near the town of Niobrara, Nebraska. The Niobrara is the largest Missouri River tributary between the last two mainstem impoundments (Lake Francis Case and Lewis and Clark Lake). Fish movement up the Niobrara is prevented by Nebraska Public Power District's (NPPD's) Spencer Hydroelectric Dam, 63.3 km upstream from the river mouth. The lower reach of the river is turbid and carries a considerable load of sand, silt, and organic debris into the Missouri River. The mean annual …

Seasonal Abundance And Habitat Distribution Of Birds In Northeastern Arkansas, Earl L. Hanebrink, Alan F. Posey Jan 1979

Seasonal Abundance And Habitat Distribution Of Birds In Northeastern Arkansas, Earl L. Hanebrink, Alan F. Posey

Journal of the Arkansas Academy of Science

Bird sighting records from 1964 through 1978 for 17 northeastern Arkansas counties were compiled according to the seasonal status, relative abundance and habitat distribution of each species. The five seasonal occurrence categories and their relative species composition were: transient visitant (46.6%), summer resident (20.3%), winter resident (14.8%), permanent resident (17.2%) and winter visitant (1.0%). The seven seasonal abundance categories and their relative species composition were: very rare (13.9%), rare 15.9%), uncommon (30.7%), fairly common (10.5%), common (25.6%), very common (1.7%) and abundant (1.7%). Eleven habitat categories were included: campestrian, abandoned fields, forest edge, lowland woods, upland woods, riparian woods, marshes, …


The Comparative Ecology Of Two Populations Of The Troglobitic Isopod Crustacean Lirceus Usdagalun (Asellidae), James Alexander Estes Jan 1979

The Comparative Ecology Of Two Populations Of The Troglobitic Isopod Crustacean Lirceus Usdagalun (Asellidae), James Alexander Estes

Biological Sciences Theses & Dissertations

Aquatic communities of two caves in Lee Co., Virginia, were compared, and an examination was made of the life history phenomena of the troglobitic isopod Lirceus usdagalun. Measurements of physical and biological parameters were made in Thompson Cedar Cave and Gallohan Cave No. l. A contagious distribution was exhibited by populations of L. usdagalun in both caves and also by the population of another troglobitic isopod, Caecidotea recurvata, in Gallohan Cave No. 1. This distribution was attributed to aggregations of individuals which were considered to occur in areas of preference or optimal habitat patches. Lirceus usdagalun exhibited a …


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 …
