Proximate And Ultimate Determinants Of Clutch Size In Anatidae, Paul A. Johnsgard

Paul Johnsgard Collection

In a stimulating analysis, Lack (1967, 1968a) reviewed waterfowl clutch size and egg size data, and concluded that interspecific variations in average clutch size are generally inversely related to those of relative egg size. Thus, he suggested that the average clutch size of each waterfowl species has evolved in relation to the average availability of food to the female around the time of nesting. He hypothesized that in waterfowl, relatively large eggs have probably evolved to provide the newly-hatched young with a large food supply (an idea he subsequently (1968b) questioned) or with an adequate insulating layer of fat. He …

Parasites Of Some Penaeid Shrimps With Emphasis On Reared Hosts, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Information is presented about parasites and commensals of penaeid shrimps, allowing those who rear shrimps and those who are interested in associated organisms of shrimp to have a better knowledge of the organisms that are or may be associated with brown, white, and pink shrimps. It covers common and rare organisms and diseases, primarily in the northern Gulf of Mexico, listing several previously unreported species including an undescribed gregarine, a larval nematode (Spirocarnallanus pereirai), a commensal nematode (Leptolaimus sp.), a leech (Myzobdella lugubris), a blue-green alga (Schizothrix calcicola), a hydroid (Obelia bicuspidata …

Critical Flicker Frequency In A Harp Seal, Pagophilus Groenlandicus (Erxleben, 1777), Charles D. Bernholz

University of Nebraska-Lincoln Libraries: Faculty Publications

Critical flicker frequency (CFF) in a free-swimming harp seal (Pagophilus groenlandicus) was investigated using behavioral techniques. The resulting CFF versus intensity contour indicates a definite rod-cone break, confirming a duplex photoreceptor population whose presence had not been observed in previous morphological reports.

Two Species Of Bats New To The Fauna Of Trinidad, Hugh H. Genoways, Robert J. Baker, R. S. Loregnard

University of Nebraska State Museum: Mammalogy Papers

Goodwin and Greenhall (1961) in their monograph of the bats of Trinidad and Tobago recorded 58 species of chiropterans from the island of Trinidad. In two subsequent publications (Goodwin and Greenhall, 1962, 1964) these authors recorded Mesophylla macconnelli, Prornops nasutus, and Phylloderma stenops from Trinidad bringing the number of species known from the island to 61. In August 1967, one of us (R. J. Baker) and Larry Deaven netted bats on Trinidad in connection with ongoing studies of chiropteran karyology, and obtained two species not previously recorded.

Bats Of Jalisco, México, Larry C. Watkins, J. Knox Jones Jr., Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

The fauna and flora of the Mexican state of Jalisco have received the much deserved attention of a number of biologists in recent years. Nevertheless, few comprehensive accounts of the biota of this interesting and physiographically diverse area have been published. In the period from 1949 to 1969, field representatives of the Museum of Natural History at the University of Kansas collected vertebrates in Jalisco. Among the specimens obtained from the state, the mammalian fauna of which never has been treated as a unit previously, were approximately 3000 bats, which form the primary basis for this report. In addition to …

Simultaneous Selection For Milk And Beef Production Among Holstein-Friesians, L. L. Calo, R. E. Mcdowell, L. Dale Van Vleck, P. D. Miller

Department of Animal Science: Faculty Publications

A selection index combining milk and beef production traits, such that progress in aggregate economic value is maximized, was constructed for Holstein bulls. The index for milk was I_M = 1.11X₁ + .997X₂ while the index for beef trait was I_B = .008X₁ + .619X₂ where X₁ is the daughters' average lactation yield (kg) and X₂, bulls' body weight at 15 mo (kg).

The relative genetic progress from simultaneous selection for milk and beef traits with different emphasis was estimated. Expected genetic progress in beef production (body weight at 15 mo) …

Mammals From Southwestern North Dakota, Hugh H. Genoways, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

The distribution of the mammals in the southwestern part of North Dakota and their ecological and taxonomic relationships have not been well documented. In addition to Vernon Bailey's (1927) survey of mammals of the state, based primarily upon field work conducted between 1912 and 1916, the only other principal studies dealing with the mammalian fauna of southwestern North Dakota were a preliminary report of the mammals of the state by Bailey et al. (1914) and the publication by J.A. Allen (1875) on mammals taken by the expedition that surveyed a route for the North Pacific Railway. Our studies, which were …

The Elusive Tree Quails Of Mexico, Paul A. Johnsgard

Paul Johnsgard Collection

The three species of tree quails or wood-partridges, genus Dendrortyx, of Mexico and Central America are all surprisingly large — weighing up to one pound in the case of the largest species — and have relatively long tails that result in an overall body length of from 9 to 16 inches. Their beaks are large and heavy, and are related to their abilities to tear apart and consume fruits, flower buds, and similar materials.

Three species of tree quails have been described, all of which occur in moist montane forests, especially the mist-shrouded cloud forests that occur at elevations …

Importance Of Different Levels Of Potassium In The Diet On Whole-Body 40K Count And Muscle And Blood Potassium , R. K. Johnson, L. E. Walters, J. V. Whiteman

Department of Animal Science: Faculty Publications

The influence of three levels (1.31, 1.03 T and 0.29% K) of dietary potassium on ⁴⁰K count, blood serum and muscle tissue potassium was determined using 36 crossbred Angus-Hereford steers. A balanced 3 x 3 latin square experimental design was utilized which allowed estimates of carry-over effects of diets to be evaluated. Diets were fed for 2-week periods and appropriate samples and measurements were collected at 14-day intervals over a 60-day period. Measurements were made on steers unshrunk and after 24 hr. off feed and water.

Carry-over effect means were nonsignificant for each trait. The steers on the high …

Extending Lactation Records In Progress To 305-Day Equivalent, J. F. Keown, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

The data consisted of 204,558 complete Holstein lactations in 2,100 herds compiled by the New York Dairy Records Processing Laboratory from 1959 to 1969 All lactation records had to have a 9th or 10th test day to be complete. The generalized least squares analysis used a model including mean, herd-year, and season-age-stage as fixed effects. The error term included random effects of con, and residual variation. Means for specified stages of lactation for milk and fat were estimated for lactations 1, 2, 3, and 4 or greater which were grouped by age of freshening, two age groups for the first …

Livestock Feeding: What Small Feeders Are Doing In Nebraska, Allen C. Wellman, Jeffrey L. Jorgensen

University of Nebraska-Lincoln Extension: Historical Materials

Specific data about how smaller Nebraska feeders are marketing their livestock has not been readily available. This is a report of a survey which was conducted in order to analyze the marketing practices of these livestock feeders and the changes in their marketing practices over a five-year period.

The objectives of this study are (1) to determine whether direct sales of fed cattle to packers is increasing in Nebraska as national trends indicate, (2) to obtain a general picture of the current state of the livestock marketing system for small feeders in Nebraska, and (3) to forecast possible trends for …

Association Of Type Traits With Reasons For Disposal, L. Dale Van Vleck, H. D. Norman

Department of Animal Science: Faculty Publications

Reasons for disposal of 3,475 cows from 188 New York Holstein herds were compared with type appraisal and milk yield in first lactation to study the relationship between type traits measured early in life and later reasons for disposal. Reasons for disposal were grouped as production (32%), udder (22%), reproduction (27%), inabilities or disease (8%), workability (3%), type (3%), and other (5%). Few traits measured before 49 months of age had any significant value in predicting the reason for a cow's eventual disposal. These results in addition to earlier studies of heritability suggest that type traits measured in the first …

The Phyllostomatid Bat, Vampyressa Brocki, In Colombia, Robert J. Baker, Hugh H. Genoways, Alberto Cadena

University of Nebraska State Museum: Mammalogy Papers

Between June 28 and July 1, 1969, while conducting studies on the karyotypes of phyllostomatid bats, the authors collected three specimens of Vampyressa brocki in mature tropical rainforest at Leticia, Amazonas. Colombia. Measurements and representative karyotypes are presented.

Variation And Ecology In A Local Population Of The Vesper Mouse (Nyctomys Sumichrasti), Hugh H. Genoways, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

Vesper mice of the genus Nyctomys are relatively rare, arboreal rodents restricted to Middle America (eastern Panama to southern Mexico). Little is known concerning the biology of these secretive animals. Studies of variation of the one species, Nyctomys sumichrasti, have been limited to descriptions of new taxa (for example, see Goldman, 1916, 1937, and Laurie, 1953) and ecological observations have been confined to faunal accounts of political units (Goodwin, 1934; Hall and Dalquest, 1963) or were made coincidental to studies of other species (Lawlor, 1969; Fleming, 1970). Birkenholz and Wirtz (1965) recorded observations on the behavior, reproduction, and early …

Potential Of Deshi Cattle Of India For Dairy Production, S. K. Moulick, R. E. Mcdowell, L. Dale Van Vleck, H. Guha

Department of Animal Science: Faculty Publications

There were 1,405 lactation records of 336 cows at the Central Livestock Research- cum-Breeding Station, Haringhata, India from 1958 to 1968 used to estimate the potential dairy merit of Deshi cattle. This breed is native to northeast India and one of the smallest breeds in India (mature females 200 kg and males 250 kg).

Averages and standard deviations for milk yield (exclusive of that suckled), age of first calving, calving interval, lactation length, days open, and days dry were 412 ± 178 kg, 44.5 ± 6.8 months, 419 ± 90 days, 264 ± 81 days, 135 ± 86 days, and …

Torrent Ducks Of The Andes, Paul A. Johnsgard

Paul Johnsgard Collection

Throughout the world there is probably no more rigorous environment for waterfowl than that provided by the Andean streams in South America. Rushing down the mountains from an altitude of 18,000 feet or more, tumbling over precipices, the streams eventually merge and grow into such giants as the Orinoco, Amazon, and Rio de la Plata on the Atlantic slope, or empty direct into the Pacific on the west side. In the intermediate elevations, mainly between 5,000 and 10,000 feet, a remarkable duck, fittingly called the torrent duck (Merganetta armata) makes its home among the rapids and cataracts. This …

A Biopsy Technique For Sampling The Gracilis Muscle In The Baby Pig, B. D. Moser, E. R. Peo, Jr., D. R. Zimmerman, P. J. Cunningham

Department of Animal Science: Faculty Publications

In research it is often desirable to measure body composition at different stages of growth. Ideally, if the same animal could be sampled several times during the growing-finishing period, critical information about tissue growth could be obtained. Thus, the development of a simple procedure to obtain tissue samples would be an asset to the researcher.

A Multivariate Analysis Of Systematic Relationships Among Populations Of The Short-Tailed Shrew (Genus Blarina) In Nebraska, Hugh H. Genoways, Jerry R. Choate

University of Nebraska State Museum: Mammalogy Papers

The genus Blarina (Mammalia: Soricidae) is represented in Nebraska by two well-differentiated, geographically exclusive phena that generally have been regarded as subspecies. Field studies conducted along their zone of contact resulted in the collection of representatives of both phena at each of five localities. Cluster analysis of distance matrix readily separated reference samples of the phena as well as test samples from near the zone of contact. A three-dimensional projection of the specimens onto their first three principal components, together with a discriminant function analysis, served further to elucidate the degree of differentiation among the phena and to confirm that …

Review Of Check List Of The Helminth Parasites Of African Freshwater Fishes, Glenn L. Hoffman

United States Fish and Wildlife Service: Publications

In spite of the fact that freshwater covers about 74,000 square miles of Africa, surprisingly little work has been done on the helminth parasites of African fishes. This well written and documented book consists of excellent parasite/host and host/ parasite check lists followed by indices of parasites and countries. As the author stated, "It is hoped that this list, combined with the increasing recognition of the importance of fish as a source of protein and, therefore, of the significance of potential pathogens, will provide the necessary stimulus to research workers to rectify these gaps."

Effect Of Fertilization And Management On The Production Of Bromegrass In Northeast Nebraska, G. W. Rehm, W. J. Moline, E. J. Schwartz, R. S. Moomaw

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Several experiments were conducted in northeast Nebraska to determine the effect of fertility and management practices on the production of smooth bromegrass (Bromus inermis Leyss). The effectiveness of the various fertilizer treatments was measured in units of dry matter produced per acre as well as beef produced per acre. Results of these studies showed that the production of bromegrass pastures in Nebraska could be markedly improved through proper fertilization.
