Quail Music: The Complex Calls Of A Bird Contain Clues To Its Evolution, Paul A. Johnsgard

Papers in Ornithology

Ethological research has revealed that the vocal communications of birds are highly specialized behavioral adaptations that can shed light on evolutionary processes. The calls of the quails of the New World are a good example. This group of birds includes some thirty species, about half of which are limited to the tropical forests of Central and northern South America. The other species are North American, ranging as far north as southern Canada. Morphological evidence favors the view that the most generalized, or “primitive,” of these species are the tree quails of Mexico’s moist mountain forests. The more open-country and arid-adapted …

Relationship Of Various Measures Of Performance With Ovulation Rate And Number Of Embryos 30 Days After Breeding In Gilts, L. D. Young, I. T. Omtvelt, R. K. Johnson

Department of Animal Science: Faculty Publications

This study involved the records of 241 purebred Duroc, Hampshire and Yorkshire gilts and 103 two-breed cross gilts resulting from all possible crosses among the purebreds. In purebred gilts, the number of corpora lutea was correlated (P < .05) with average daily gain (r = 0.15), age at 100 kg(r =-.17), breeding weight (r = 0.23) and days from 100 kg to breeding(r= 0.20). In two-breed cross gilts, the number of corpora lutea was correlated (P < .05) with birth weight (r = 0.25), weaning weight (r = 0.28), average daily gain (r = 0.20), age at 100 kg (r = -.20) and breeding weight (r = 0.46).

The size of the litter the gilt was born or weaned in, her birth weight, average daily gain, age at 100 kg, and backfat probe were not significantly correlated with the number of embryos she had 30-days postbreeding regardless of the type of breeding of the embryo. The correlation between the gilt's weaning weight and number of embryos was significant (P<.05) for gilts with three-breed cross embryos but not for gilts with purebred or two-breed cross embryos (r = 0.35, 0.02 and 0.11, respectively). Breeding age and days from 100 kg to breeding were correlated (P<.05) with the number of embryos for gilts with two-breed cross embryos (r = 0.17 and 0.15, respectively) but these correlations were not significant for gilts with purebred embryos (r = -.13 and -.05, respectively) or for gilts with three-breed cross embryos (r = -.05 and 0.14, respectively). The correlation between breeding weight and number of embryos was significant for gilts with two-breed cross and three-breed cross embryos (r = 0.15 and 0.41, respectively) but not for gilts with purebred embryos (r = -.03). Ovulation rate accounted for 13.7, 5.8 and 23.0% of the variation in the number of purebred, two-breed cross and three-breed cross embryos, respectively (P < .05).

A New Vespertilionine Bat From The Barstovian Deposits Of Montana, John F. Sutton, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

During the 1972 field season, a small collection of micromammals was obtained from the Anceney Local Fauna located 13 miles west of Bozeman, Gallatin County, Montana. The fauna is Barstovian in age (Upper Miocene) and is preserved in an ash-filled channel deposit in the Madison Valley Formation (Dorr, 1956). A single partial jaw of a chiropteran was recovered along with numerous bones and teeth of other mammals, birds, amphibians, and reptiles. The jaw is complete from incisors back to the level of the m2. Examination of the jaw and comparisons with Recent and fossil chiropterans has convinced us that it …

Review Of Curassows And Related Birds, Paul A. Johnsgard

Papers in Ornithology

To contemplate the appearance of a new book dealing for the first time with an exhaustive coverage of an entire avian family is to evoke an excitement that is all too rare an occurrence for most ornithologists. This excitement is enhanced when the bird group is one of the least studied and yet, evolutionarily speaking, most significant of the galliform families, and when the authors are as well known and highly respected as Delacour and Amadon. Anticipation reaches its apogee when the contributing artists are as competent as Albert E. Gilbert, George M. Sutton, and David Reid-Henry. After reading the …

Influence Of Nutritional Regime On Age At Puberty In Gilts, P. J. Cunningham, C. H. Nabor, Dwane R. Zimmerman, E. R. Peo, Jr.

Department of Animal Science: Faculty Publications

Age at puberty was determined for 205 Gene Pool gilts; 68 fed a 10% protein diet (HLC) consisting of high-lysine corn, minerals and vitamins and 137 fed a 14% protein corn soybeam meal diet (CS). Gilts fed the CS diet reached puberty 18.7 days earlier than gilts fed the HLC diet. Use of post-weaning daily gain as a covariable reduced the difference between diets to 9 days. The pooled within diet regression of age at puberty on post-weaning gain was -22.75 days per kilogram. The correlation between pubertal age and daily gain was significantly higher on the HLC diet (-.30 …

Effect Of Dietary Calcium And Phosphorus Level Upon Calcium, Phosphorus And Nitrogen Balance In Swine, P. E. Vipperman, Jr., E. R. Peo, Jr., P. J. Cunningham

Department of Animal Science: Faculty Publications

Three metabolism trials were conducted to determine the effects of dietary calcium and phosphorus level upon calcium, phosphorus and nitrogen balance in growing swine. The nine pigs in each trial averaged 22.6, 25.2 and 26.5 kg initially for trials 1, 2 and 3, respectively. The diets contained three levels of calcium and three levels of phosphorus and were rotated among the pigs in the three trials. Feed intake was adjusted to metabolic size.

Review Of Parasites Of Freshwater Fishes, Ross F. Nigrelli

United States Fish and Wildlife Service: Publications

The title of this paperback should be "The Treatment and Control of Parasites of Freshwater Fishes," since a therapeutic armamentarium is its chief feature. This information, which was collected from many, often obscure, sources, is the most comprehensive collection of data on the subject that has ever been assembled and published. As pointed out by Drs. Hoffman and Meyer, two outstanding authorities on fish diseases, the efficacy of many of the chemicals listed has not been critically evaluated, and some of them should be used with caution. To this end, they have included a table which gives the toxicity limits …

Polypodium Sp. (Coelenterata) Found In North American Sturgeon, Glenn L. Hoffman

United States Fish and Wildlife Service: Publications

On 27 May 1970, Mason Shouder, Michigan Fisheries Biologist, discovered some abnormal eggs in a ripe sturgeon, Acipenser fulvescens. The fish were taken from the Black River near Cheboygan, Michigan, which is barricaded from Lake Huron by a dam built in the 1920's. Normal ripe eggs were black spheres; the abnormal ones were enlarged and grayish (Fig. 1). About 20% of the eggs were affected and attached to the wall of the uterus in saclike structures. The ovary was also abnormal, being flaccid. In May 1973, a single infected egg was found in vodka-prepreserved eggs from a ripe sturgeon …

Interspersed between the charts are full-page or half-page color plates illustrating the parasites and the appearance of their infections in fish. There are 108 illustrations (all but 2 in color) on 57 pages, constituting more than 25% of the book's length and resulting in …

Review Of Fish Pathology: A Guide To The Recognition And Treatment Of Diseases And Injuries Of Fishes, With Emphasis On Environmental And Pollution Problems And Parasites Of Freshwater Fishes: A Review Of Their Control & Treatment, Ross F. Nigrelli

United States Fish and Wildlife Service: Publications

Fish Pathology states in its subtitle that it is "A guide to the recognition and treatment of diseases and injuries of fIshes with emphasis on environmental and pollution problems." These topics were included in the author's earlier volume "Krankheiten und Schadigungen der Fische" (Gustav Fischer Verlag, Stuttgart, 1966) and are only slightly revised in . this English translation by Christa Ahrens. Fish Pathology deals briefly but inadequately with semiology and histopathologY but it is a good introduction to information on infectious, parasitic, and nonparasitic diseases of fishes, and to such subjects as the harmful effects of pollutants and abnormal environmental …

The Taxonomy And Relationships Of The Northern Swans, Paul A. Johnsgard

Paul Johnsgard Collection

The recent (1972) publication of the Wildfowl Trust's book The Swans has brought together an unprecedented array of information on all of the swans of the world, and makes it desirable to raise once again the question: how many species of northern swans are there, and what are their evolutionary relationships to one another? Delacour (1954) suggested the comprehensive vernacular name 'northern swans' to distinguish 'the various knobless white swans which breed in or near the Arctic parts of the northern hemisphere' from the Mute Swan (Cygnus olor) and the three southern hemisphere swans. The northern swans have …

Cytotypes And Morphometrics Of Two Phyllostomatid Bats, Micronycteris Hirsuta And Vampyressa Pusilla, Robert J. Baker, Hugh H. Genoways, William J. Bleier, Jerry W. Warner

University of Nebraska State Museum: Mammalogy Papers

As pointed out by Jackson (1971) and Patton (1972), the key to understanding mechanisms of chromosomal evolution lies in studies of chromosomal variation within populations that can hybridize. Hybrids between cytotypes contain the answer to problems of meiotic pairing and reduced fertility, as well as information concerning the nature of zones of contact. However, before detailed studies can be initiated, chromosomal races and hybrid zones must be located. Few chromosomal races have been described for bats (Baker, 1970a). Within the family Vespertilionidae, five species are known to have such races (Baker, 1970a) and races have been reported in two species …

How Many Cranes Make A Skyful?, Paul A. Johnsgard

Paul Johnsgard Collection

Every year thousands of lesser sandhills congregate along the Platte River in Nebraska on their spring migration northwards. Mainly because of local damage caused by the birds during their fall migration, they have been legally hunted since 1961. Can the population survive such persistent destruction?

One may ask the question “How many cranes are enough?” This is perhaps analogous to the rhetorical question as to how many redwood trees are needed to make a viable forest; for a remnant crane population is not only unimpressive but also seemingly does not survive or reproduce well, judging from population trends in the …

Systematics And Evolutionary Relationships Of Spiny Pocket Mice, Genus Liomys, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Introduction

Spiny pocket mice of the genus Liomys are members of the rodent family Heteromyidae and together with the genus Heteromys form the subfamily Heteromyinae. Their geographic range extends from northern Sonora, in western Mexico, and southern Texas southward to the vicinity of the Panama Canal Zone. Within this area, members of the genus occur mainly in dry to arid situations being replaced in areas of rain forest and cloud forest by members of the genus Heteromys. The vernacular name for Liomys is based on the fact that many of their hairs have been modified in the form of …

Nongeographic Variation In The Long-Nosed Bat, Choeroniscus Intermedius, Hugh H. Genoways, Robert J. Baker, Bernard Wyatt

University of Nebraska State Museum: Mammalogy Papers

Of the 12 measurements analyzed, only length of tail exhibited enough individual variation to warrant its deletion in analysis of geographic or interspecific variation in the genus Choeroniscus. Also, because of the difficulty in consistently taking the measurement, we also suggest elimination of postorbital constriction.

Specimens of Choeroniscus intermedius were found to exhibit significant secondary sexual variation in five of the 12 measurements studied. Therefore, it is clear that males and females should be separated in analyses of variation within members of the genus. Females were found to be the larger in 10 of the 12 measurements--similar to the …

Reproductive Efficiency Of Purebred And Crossbred Dairy Cattle, R. E. Mcdowell, J. A. Velasco, L. Dale Van Vleck, J. C. Johnson, G. W. Brandt, B. F. Hollow, B. T. Mcdaniel

Department of Animal Science: Faculty Publications

Nine measures related to breeding efficiency were used for comparisons among purebred Ayrshires, Brown Swiss, Holsteins, and Jerseys and between purebreds and 32 crossbred groups representing 2-breed, 3-breed, 5/8, and backcrosses by purebred sires and progeny of crossbred sires. There were four herds with Holsteins common to all, Brown Swiss and Jerseys in three herds and Ayrshires in one herd. Four 2-breed, two 3-breed, and two backcross groups were common to two or more herds. Among purebreds, breed effects were significant in 16 of 72 tests, but there was no consistent trend favoring one breed. Generally, Jerseys were better than …

Evaluation Of Purebreds And Two-Breed Crosses In Swine: Reproductive Performance, R. K. Johnson, I. T. Omtvedt

Department of Animal Science: Faculty Publications

The data included records on 440 purebred sows and gilts of Duroc, Hampshire and Yorkshire breeding mated in all combinations to produce purebred and two-breed cross litters. A total of 119 purebred gilts (39 with purebred litters and 80 with crossbred litters) were slaughtered 30-days postbreeding and their reproductive tracts evaluated for number of corpora lutea and early embryo development. Farrowing records included 89 purebred and 161 two-breed cross litters produced at the Ft. Reno Experiment Station during the spring and fall of 1971 and the summer of 1972.

Reproductive failures (females not exhibiting estrus or open at slaughter or …
