Whooping Crane Roost Site Characteristics On The Platte River, Buffalo County, Nebraska, Gary R. Lingle, Kenneth J. Strom, Jerry W. Ziewitz

Nebraska Bird Review

Whooping Crane (Grus americana) use of the Platte River in Nebraska has been a controversial topic, especially in the last decade. Pressures from water development interests seeking Platte River water conflict with the needs of wildlife and interests from the conservation community. Between spring 1942 and fall 1984 there were 13 confirmed Whooping Crane sightings on or near the Platte River (US Fish and Wildlife Service, 1985). Lingle et al. (1984) described physical characteristics of a Platte River roost site used in 1983. This report describes the physical characteristics of the most recent known roost site on the …

Mottled Duck In Nebraska, W. Ross Silcock, Tanya Bray, Babs Padelford

Nebraska Bird Review

The two major US populations of Mottled Duck occur in Florida and along the Gulf Coast in Louisiana and Texas, with local breeding inland to “southeast Colorado, western Kansas, Oklahoma (rarely), and northeast Texas” (AOU Checklist of North American Birds, Sixth Edition, 1983). Palmer (Handbook of North American Birds, Vol. 2, 1976) notes that Mottled Duck bred in 1963 at Cheyenne Bottoms, Kansas, and that some individuals occur inland beyond the usual breeding range during the post-breeding period. Presumably these inland. records pertain to birds from the Texas-Louisiana population, as the Florida birds are generally considered nonmigratory. …

Descriptive Ethology And Activity Patterns Of Black-Footed Ferrets, Tim W. Clark, Louise Richardson, Steven C. Forrest, Denise E. Casey, Thomas M. Campbell Iii

Great Basin Naturalist Memoirs

Aspects of the aboveground ethology and activity patterns of the black-footed ferrets (Mustela nigipes) are described for a population in northwestern Wyoming as a first step in building a descriptive ethogram and quantification of activity patterns. We observed at least 237 individual ferrets for 208 hr on 441 occasions from 2 December 1981 through 25 September 1984. Mainenance behaviors (locomotion, alert, grooming, and sunning, defecation and urination, digging, and predation) and social behavior (reproduction, ontogeny, maternal, play, agonistic) are described as well as some ferret-human interactions. Ferret vocalizations are subjectively described. We located ferrets during most months including …

Effect Of Spring Grazing By Cattle On Growth And Survival Of Shrub Seedlings Interplanted In Crested Wheatgrass, Lynn M. Mcconville

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A short duration-high intensity grazing trial was conducted in spring of 1985 to determine whether shrub establishment in crested wheatgrass pastures could be enhanced through spring grazing by cattle, or by fertilization of shrub seedlings. Data was collected on diet selection by cattle during spring grazing, and on subsequent shrub growth and survival. Shrubs studied were transplants of sagebrush, Artemisia tridentata, fourwing saltbush, Atriplex canescens, bitterbrush, Purshia tridentata, and one year old bitterbrush seedlings.

Cattle did not browse sagebrush or fourwing saltbush transplants, but utilization of bitterbrush transplants and seedlings averaged 15 and 42 percent, respectively. Shrub …

Vulnerability Of Cougars To Hunting, Dan Barnhurst

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Forty radio-collared cougars (Felis concolor) were monitored for 630 cougar months. Track searches were conducted and tracking information was gathered over a 20-month period. Vulnerability was estimated to be greatest for 0 to 6-month-old kittens. This age class is the most susceptible to starvation after being orphaned, or being killed by hounds when the hunter is unaware of their presence, since their tracks were found with their mother's tracks only 19 percent of the time. Tracks of 7 to 12-month old kittens were found with their mother's tracks 43 percent of the time. Relative road-crossing frequencies of seven …

Factors Affecting Puberty, Estrus And Ovulation In Corriedale And Criollo Sheep Of The Southern Peruvian Highlands, Pedro Walter Bravo Matheus

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This research was conducted at the La Raya experiment station, Cusco, Peru (4200 m elevation, 15°S latitude, and 70 °W longitude) using 60 Corriedale, and 60 Criollo ewes during three consecutive years (April 1981 - March 1984). Age, and weight at puberty, age at physical maturity, and the effects of breed, age (physically immature and mature), year, and month were measured on body weight, incidence of estrus, and incidence and rate of ovulation. There was a significant difference (P<.05) among breed, year, and the interactions for body weight at puberty. The mean age at puberty for 1982-83 was 693.6 days (23.1 months) for Corriedale and 483.3 days (16.1 months) for Criollo. The mean liveweight at puberty was 27.2 kg for Corriedale, and 25.3 kg for Criollo. Corriedale ewe lambs weighed more than Criollo, attained puberty seven months later than Criollo. At comparable age (15-17 months) at the Southern Peruvian Highlands 100 % of the Criollo reached puberty, compared to 58% of the Corriedale. Body weight, incidence of estrus and ovulation were affected (P<.01) by breed, age, year, month, and their interactions. Physical maturity was attained at 39 and 36 months of age for Corriedale, and Criollo, respectively. Weight changes during the year were associated with feed availability. The mean overall incidence of estrus was 45.4 % for Corriedale (43.6 in physically immature, and 47.2 % in mature ewes), and 67.1 % for Criollo ewes (66.3, in physically immature, and 68.7 % in mature ewes). The mean overall incidence of ovulation was 39.6 % for Corriedale (39.7, in physically immature, and 39.5 % in mature ewes), and 58.5 % for Criollo ewes (59.4, in physically immature and 56.7 % in mature ewes). Both breeds demonstrated seasonality of estrus and ovulation with the Corriedale being shorter than the Criollo. The incidence of ovulation in both breeds was less than that of estrus. The ovulation rate was 1.00 for Corriedale, and 1.03 for Criollo (P>.05). Even though Criollo ewes weighed less than Corriedale, they attained puberty earlier, and showed less seasonality in estrus and ovulated …

Aspects Of The Feeding Ecology Of The Bonneville Cisco Of Bear Lake, Utah-Idaho, David C. Lentz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Bonneville cisco (Prospium gemmiferum), a small planktivorous whitefish, is an important part of the distinctive fish community of Bear Lake, Utah-Idaho. The Bonneville cisco plays a key role in the trophic structure by converting zooplankton to fish biomass and providing a major forage source for cutthroat and lake trout. Aspects of cisco feeding ecology studied include characterization of the zooplankton community composition and dynamics and cisco feeding habits and prey selection.

Composition and seasonal dynamics of the zooplankton community were determined for a fifteen month period during 1981-1982. The community was dominated by a calanoid copepod, Epischura …

Manganese Toxicity In Mice: Evaluation Of Neruochemical And Immunologial Alteration, Benjamart Srisuchart

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Neurochemical and immunological effects of manganese chloride (MnCl₂) were evaluated using young male CD-1 mice as the animal model. Intraperitoneal (i.p.) injection of MnCl₂ (1, 3 and 10 mg/kg) daily for 4 weeks did not produce mortality or overt signs of toxicity in any of the treated animals. Manganese treatment increased the thymidine uptake of cultured splenic cells and the selective lymphoproliferative response to T-cell mitogens, phytohaemagglutinin and concanavalin A, in all the treated groups. No difference in the response to B-cell mitogen, lipopolysaccharide was observed. A dose of 10 mg/kg MnCl₂ increased the mixed lymphocyte …

Comparison Of Heritability Estimates From Daughter On Dam Regression With Three Models To Account For Production Level Of Dam, J. C. Deveer, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Three models were used to estimate heritabilities for milk yields at different production levels and for different years as twice the regression of daughter residual effects on dam residual effects. The denominator is the residual mean square for dams. The numerator is the difference between the residual term for sum of dam's and daughter's records and sum of residual terms for records of dams and daughters. Model 1 included sire of daughter and herd-year-season of daughters only. Model 2 included sire of daughter, herd-year-season of dam, and herd-year-season of daughter. Model 3 included sire of daughter and herdyear- season of …

The Diet Of The Gopher Tortoise, Gopherus Polyphemus, In A Sandhill Habitat In Central Florida, Laurie Ann Macdonald

USF Tampa Graduate Theses and Dissertations

Scat analysis and foraging observations were used to determine the diet of a gopher tortoise, Gopherus polyphemus, population in a sandhill community in west central Florida. Live vegetation was assessed to determine plant availability. The bulk of the gopher tortoise diet was composed of the dominant plant species in the habitat while the tortoises were selective with respect to most plant genera. Tortoises ingested many plant taxa with Poaceae, Asteraceae, Fabaceae, Pinaceae and Fagaceae being the most frequent components of the diet. Sixty-eight genera from 26 families were identified in the tortoise diet. In the scat the most common …

The Report Of The Southern Western Australian Shark Working Group., P. Millington

Fisheries Management Papers

The southern Western Australian Shark Working Group was formed to investigate the southern shark fishery and advise the Minister for Fisheries on options for future management. Membership comprised six fishermen from regional professional fishermen's associations and two Fisheries Department officers. The Working Group considered that each shark fisherman obtaining an entitlement should then be restricted in the length of fishing gear he can use and the number of months he can fish. The individual's time and gear entitlement would be approximately that length of gear being used and time spent fishing in a period shortly before the bench mark date. …

Variation In Piglet Weights: Relationship To Suckling Behavior, Parity Number And Farrowing Crate Design, David Fraser, B. K. Thompson

Ontogeny Collection

Suckling behavior and weight change of piglets were studied during the first 2 wk after birth. Thirty-six litters comprised a balanced comparison of parity number (first or second), litter size (8, 10 or 12), and two farrowing crate designs, one of which had a low horizontal bar that tended to impede the piglets' access to the udder. Piglets showed the expected preference for the anterior teats although the preference was more apparent in the second parity than in the first. Teat fidelity was most pronounced at the two ends of the udder; piglets occupying the middle positions did more fighting …

Variations In Radial Maze Performance Under Different Levels Of Food And Water Deprivation, Robert H.I. Dale, William A. Roberts

Scholarship and Professional Work - LAS

Four groups of rats were tested on an eight-arm radial maze under a free-choice procedure. The subjects were maintained at either 80% or 100% of their preexperimental free-feeding weights through restricted access to either food or water. Water-deprived subjects received water in the maze; food-deprived subjects received food. Water-deprived subjects learned the task faster than food-deprived subjects. The four groups developed different response patterns. These were measured by the mean transition size, the average angular distance (in 45° units) between consecutively chosen arms. Rats foraging for food and water developed different search strategies, with water-deprived subjects exhibiting lower mean transition …

Hybrid Bluebird Update, Barbara L. Wilson, Jim Minyard, Hope Minyard

Nebraska Bird Review

The female Mountain Bluebird and male Eastern x Mountain Bluebird nesting in Dawes Co. (NBR 53: 67) successfully fledged two broods, each with four young, in the summer of 1985. Young from the first nesting fledged in the last week of June. About 1 July the parents renested. Since the pair was observed copulating, it is highly probable that the hybrid male was the father of the young to be raised.

In mid-July the eggs hatched, but at this time the female became obviously ill. She sat on a fence with feathers ruffled and did not feed the young. …
