Field Exposure of Two Upland Cover Types to Solid Rocket Motor Fuel Emissionsi A series of replicated field experiments in which two important upland cover types were exposed to solid rocket motor fuel emissions did not reveal any immediate impact on the vegetation. Soil pH and Cl- concentrations remained unchanged. Root biomass one year after exposures was not significantly different among the treatments. Likewise, twig growth of two browse species, dwarf live oak (Quercus minima) and myrtle oak (Q. myrtifolia), was unimpaired.

Summer Home Ranges and Movements of Bobcats in Bottomland Hardwoods of Southern Louisiana An ecowgical study of the bobcat (Lynx rufus) was conducted in bottomland hardwood habitats in Louisiana over a 2-year period to evaluate movement and activity patterns. Six bobcats, trapped in spring and summer of 1973, were equipped with radio-transmitting collars and their movements subsequently.monitored with portable receiving equipment. Three adult male bobcats had an average minimum home range of 494.1 ha and 3 females limited their movements to an average of 97.1 ha.

Avian Species Diversity in Relation to Beaver Pond Habitats in the Piedmont Region of South Carolina The seasonal structure of avian communities associated with beaver pond habitats was studied by examination of bird species diversity. Beaver pond avifaunas were highly diverse during every season but reached maximal values during the spring and summer. The importance of beaver ponds as wildlife habitat is due to a series of factors related to their structural complexity. As a result, they attract birds which are normally not associated with wetland habitats and provide excellent opportunities for multiuse wildlife management.

Status of Beaver in South Carolina as Determined by a Postal Survey of Landowners In 1975, a postal survey of4,500 landowners was conducted in South Carolina concerning the presence of beavers (Castor canadensis carolinensis) on their property. Ofthe 956 questionnaires returned, 239 (25 percent) confirmed the presence of beaver activity. During the past 10 years beaver populations have increased significantly in the Savannah and Pee Dee River drainages and currently they are distributed in 28 of the 46 counties in the state. Beavers inhabit 747 kilameters of stream and/or lake shoreline and affect a minimum of 7,138 hectares of bottomland.

Evaluating Beaver Guards on Restricted Flow Risers of Flood Control Impoundments Eight types of guards, designed to prevent plugging of restricted flow risers by beaver, were tested on Soil Conservation Service flood control impoundments. The effectiveness of these guards was studied between August 1975 and September 1976. Four guard types were unsuccessful in preventing plugging of risers by beaver. Risers protected by the other four guard types were not plugged, although some had been plugged prior to the installation of the guards. A guard similar to type 5 showed the most promise for preventing plugging.

Preliminary Study Using Chemosterilants for Control of Nuisance Beaver Sixteen beauer (Castor canadensis) were liue trapped, marked, and orally administered the chemosterilants 17 a-ethynylestradiol-3-cyclopentyl ether and SC-24674 ofSearle Laboratories. Treated beauer were released at the point of capture and retrapped near the end of the breeding season. Fiue treated breeding age males showed significant reduction in both testes weight (P<1J.01) and seminal uesicle weight (P<0.05) as compared to untreated males.

Damage to Loblolly Pine by Winter Roosting Blackbirds and Starlings Roosting blackbirds and starlings (Sturnus vulgaris) caused extensive damage to a 4-hectare, 14-year old loblally pine (Pinus taeda) stand near Shannon, Georgia. Over a 4-year period, a one million-bird roosting population killed 96 percent of the pines on a 2-hectare area, which resulted in a loss of $51.80 per hectare. Black and white panchromatic and infrared film exposed from 150 to 250 meters altitude effectively delineated areas of tree stress and mortality.

Relationship Between Body Weight and Heart Girth in White·Tailed Deer from South Carolina Relationships between heart girth and body weight were determined in 545 white-tailed deer (Odocoileus virginianus) killed in South Carolina during the period September 1965 to December 1966. Data for heart girth, total body weight, and "hog-dressed" weight were recorded for 102 male fawns. 127 female fawns. 113 adult males, and 203 adult females. Data for males and females were pooled. Prediction equations developed for hog-dressed weight. (W, lb.) based on heart girth, (H, in.) were: W = 3.9499H - 55.6158 (R' = 0.71) for fawns; and W = 5.6037H - 94.0982 (R' ~ 0.74) for adults.

Observation on Injuries in White-Tailed Deer The frequency of chronic debilitation of white-tailed deer (Odocoileus virginianus) due to traumatic injuries was estimated from necropsy records on 1,002 animals collected for scientific purposes throughout the southeastern United States. Evidence of previous injury was present in 76 deer (7.6 percent). Percentages of injured deer did not vary significantly according to sex, physical condition, or six-month periods associated with high or low hunting pressure. Incidence of injury increased with age for both sexes but was statistically significant only for does.

Allele frequency data for the b-hemoglobin locus from 452 white-tailed deer (Odocoileus virginianus) from the Savannah River Plant were examined for spatial subdivision of the herd. The usefulness of electrophoretic techniques to gather genetic information for analysis of spatial subdivision is demonstrated. Significant spatial heterogeneity was found; thus, the herd probably consists of more than one functional population. The potential use of these populations as independent management units is discussed.

Mortality of White-Tailed Deer Fawns in the Wichita Mountains, Oklahoma Thirty-five white-tailed deer (Odocoileus virginianus) fawns 1 to 28 days of age were captured in 1974 and 1975. Survival and causes of mortality were determined by radio telemetry. Average annual mortality was 87.9 percent, based on a 63 percent mortality rate in 1974 and a 96 percent mortality rate in 1975. Predation by coyotes (Canis latrans) and bobcats (Lynx rufus) was involved in 96.6 percent of the observed mortality. Salmonellosis was detected in three 1975 fawns at capture but clinical symptoms of the disease were not noted during the study.

Browse Quality Affected by Pine Site Preparation in East Texas An east Texas pine-hardwood forest was clearcut in 1972, and selected sites were burned, chopped, KG bladed, or left untreated in the winter of 1973-1974. Crude protein, calcium, and phosphorus content in leaves and twigs of four browse species were measured in April, September, and November after site preparation. Among site treatments, burning usually resulted in highest nutrient contents, followed by chopping, control, and KG blading.

Deer Forage Production Associated with the Practice of Site Conversion in a North Carolina Pocosin A study was made to determine the effects of site conversion on the production of forage for deer on industrial timberlands in an eastern North Carolina pond-pine pocosin. Natural as well as site prepared regenerated stands were sampled. The diversity of species was significantly greater on regenerated sites than either of the two types of natural sites. As a result of site conversion forage production was increased reaching a maximum of 728 kilograms per hectare during the fourth growing season compared to a maximum of ]00 kilograms per hectare for the natural sites.

Movements, Home Range, and Cover Use: Factors Affecting the Susceptibility of Cottontails to Hunting Winter home ranges for 19 telemetered cottontails (Sylvilagus floridanus) aueraged 2.8 ha for males and 2.2 ha for females. Home ranges determined from retrap and reobseruation data for ear-tagged rabbits aueraged 5.6 ha for males and 1.2 ha for females. Cottontails preferred smaller areas within their existing home ranges for diurnal couer. The area within each rabbit's home range in which the rabbit was found in 80 percent or more of the diurnal readings was designated as the diurnal couer preference range IDCPR).

Urban Wildlife and Community Health: Gray Squirrels as Environmental Monitors This paper emphasizes the value of urban wildlife as environmental monitors for hazards of public health concern. A comprehensive model, utilizing gray squirrels, (Sciurus carolinensis) was developed through the collaboration of wildlife biologists and investigators in allied disciplines. This study includes 1) documentation of the diseases and parasites of squirrels which are potentially pathogenic for humans, 2) evaluation of the squirrel as an indicator of radioactive materials, pesticides and heavy metals and 3) baseline information on the biology and physiology of the species.

A Comparison of Some Census Techniques for the Cottontail Rabbit For comparative purposes four census techniques were applied to livetrapping data from native cottontail (Sylvilagus floridanus) populations in two beagle field trial enclosures. On both areas the Virginia Polytechnic Institute-Grouped Lincoln Index, the Schnabel and the Schumacher-Eschmeyer methods yielded similar estimates; the Eberhardt method yielded estimates which were approximately double the others. Stocking of rabbits on both enclosures provided populations of known density for testing the accuracy of the estimators.

Squirrel and Rabbit Abundances in the Atchafalaya Basin, Louisiana Relative abundances ofgray squirrels (Sciurus carolinensis), fox squirrels (Sciurus niger), and swamp rabbits (Sylvilagus aquaticus) were determined in three main forest types of the A tchafalaya River Basin. Squirrel observations and rabbit fecal pellets were used to index population densities. Squirrel abundance varied by overstory type (P<0.0l) and was highest in bottomland hardwoods (CeltisFraxinus- Liquidambar-Ulmus). A significant difference was not indicated between squirrel densities in cypress-tupelo (Taxodium-Nyssa) or cottonwood-willow-sycamore (Populus-Salix-Platanus).

An Evaluation of the No. 2 Victor And 220 Conibear Traps in Coastal Louisiana During the 1974-75 trapping season an evaluation of the No.2 Victor leg-hold trap and the 220 Conibear trap was conducted in nine study areas consisting of fresh and brackish marsh along the Louisiana coast. Twenty-three trappers produced 10,671 trap nights of evaluation with the No.2 Victor and 7,567 trap nights of evaluation with the 220 Conibear. The No.2 Victor caught significantly more (p<05) nutria (Myocastor coypus) in both fresh and brackish marsh study areas.

Inventorying Habitats and Rating Their Value for Wildlife Species A team of experienced biologists developed line charts to inventory the important components of wildlife habitat and transformation charts to convert the inventoried characteristics to habitat values for specific species for a Maryland Piedmont watershed. The line chart system gave results equivalent to the procedure recently developed by the U. S. Fish and Wildlife Service with less field time. In addition, the line charts display the basis for all conclusions, provide a simplified base for determining future conditions, and are easily adapted to computer analysis.

Control of a Fowl Cholera Outbreak among Coots in Virginia In February, 1975, an outbreak of fowl cholera caused the death of 18,000 wild waterfowl, primarily American coots (Fulica americana), at Back Bay, Virginia. To arrest the epornitic, coots were treated with aerial application of a wetting agent, rendered flightless, collected from the water, and humanely destroyed. Over 6,000 coots were depopulated. Pertinent field observations are described for this control endeavor.

Reproductive Success of the Resident Canada Goose Flock at the Eufaula National Wildlife Refuge During 1975 and 1976, a total of 75 Canada goose (Branta canadeneis) nests were located in the Eufaula area. Of all nesting attempts found, 41 percent in 1975 and 51 percent in 1976 hatched at least one gosling. Nest mortality. was due mainly to high water levels with predation, human interference, and competition for nesting territories also contributing. Minimum number of goslings raised per successful nest was 1.5 in 1975 and 2.9 in 1976. At least 81 goslings were raised to flight stage during these two nesting seasons.

Bird Usage by Habitat Types in a Large Freshwater Lake Winter and summer bird numbers were determined for four aquatic habitats in Miller's Lake, Evangeline Parish, Louisiana. As the succession of the vegetation progressed from open water to water tupelos (Nyssa aquatica), the number of bird species occurring in each habitat increased during both seasons, and the number of individuals and avian species diversity increased during summer. Bird numbers in each habitat were higher in winter than summer.

Plant Succession after Saw-Grass Mortality in Southwestern Louisiana A mortality of saw-grass (Cladium jamaicense) and other plants occurred between 1957 and 1961 in southwestern Louisiana involving 162,000 ha.of marsh. Flooding and high salinities associated with Hurricane Audrey (June 1957) and subsequent droughts are blamed. Plant succession in an area affected by the die-off was studied by line-intercept transects on the Lacassine National Wildlife Refuge from 1958 through 1974. In 1958, 86 percent of the area sampled by the transect lines was open water while only 2 percent was open water in 1974.

Diethylstilbestrol Effects on Antler and Reproductive Gland Morphology in Male Deer Silastic tube-type implants containing diethylstilbestrol (DES) were placed subcutaneously in five male white-tailed deer (Odocoileus virginianus). Implants were recovered from four deer and determined to have a mean daily release rate of 205 ug. At this rate DES drastically suppressed antler growth, but the velvet was shed and bone antlers were formed. Treated males had significantly lower testes weights than controls. However, DES affected spermatogenesis but the response was not uniform, ranging from almost complete cessation to limited sperm production.

Sex Ratios, Morphology and Condition Parameters of Muskrats in East Tennessee Muskrats (Ondatra zibethicus) were collected from river and creek study areas in East Tennessee from July 1972 to June 1973. An imbalance in sex ratios was found to be seasonal and an overall sex ratio approaching 1:1 is likely the actual case. Significantly heavier body weights of river versus creek animals likely reflects the more abundant and/or higher quality food supply present on the river than on the small creek.

Characteristics of Mississippi Game Law Cooperatorsi A self-administered questionnaire survey of 104 Mississippi game law cooperators (i.e. persons who report wildlife violations) was conducted in 1975. In addition, violation reports received from cooperators were analyzed. Generally, cooperators thought game law enforcement was "ineffective" but "fair," and that agents made "too few" arrests. Most cooperators felt "good" toward game laws but thought fines levied against violators were "too low. "All cooperators opposed violators. The majority of cooperators reported that "a lot" of violations occurred in their residence county.

The Establishment of Spotted Bass Fisheries in Some Northern Missouri Streams Spotted bass were propagated and stocked by the Missouri Deparbnent of Conservation into 16 northern and central Missouri streams to establish spotted bass fisheries. Until recently, spotted bass in Missouri, were confined to the southern half of Missouri primarily in the lower reaches of large streams. A review of spotted bass habitat requirements as detennined by earlier studies indicated that spotted bass might thrive in some ofthe northern Missouri streams which are too silty or turbid for the other black basses.

Attraction of Native Fish to Catfish Culture Cages in Reservoirs Experimental gill nets were fished at sites with and without cages in which catfish were fed pelletoo feed in lakes Hartwell and Keowee, South Carolina, during 1972, 1973, and 1974. Native fishes were indentified, counted, and weighed. Of34 species captured in the two lakes the most numerous were threadfin and gizzard shad, carp, bullhead species, white bass. bluegill, and largemouth bass. Total numbers of fish caught in each lake were greater at cage sites than at control sites after stocking cages. Harold A. Loyacano, Jr., David C. Smith

Production of Hybrid (Blue X Channel) Catfish and Channel Catfish in Ponds Hybrid (blue lctalurus furcatus x channel l. punctatus) channel catfish were grown separately at 3000/acre in 0.1-acre ponds for a growth period of 220 days. The average net yield was 3,752 pounds/acre for the hybrid catfish and 3,262 pounds/acre for the channel catfish. This difference was significant (P<0.0l with the hybrid catfish averaging 13.5 percent more pounds/acre than the channel catfish. When the two fish were compared in other commercially important aspects, the hybrid catfish was captured more easily by seining, more uniform in size, and had greater dress·out percentage. D.
