The Platte River Ecology Study: Special Research Report', Northern Prairie Wildlife Research Center Jun 1981

The Platte River Ecology Study: Special Research Report', Northern Prairie Wildlife Research Center

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Each spring about 80%of the sandhill cranes in North America stop for several weeks in the Platte and North Platte River Valleys of Nebraska while en route to breeding grounds in Canada, Alaska, and the Soviet Union. This concentration of cranes is unparalleled in North America and these sites represent the principal spring staging areas for the midcontinent population. Large numbers of waterfowl, numerous bald eagles, whooping cranes, and many other species also use the area.

Recent changes in habitat conditions along the Platte and North Platte Rivers have prompted concern for the welfare of sandhill cranes and other migratory …

Herpetofauna Of Mormon Island Preserve Hall County, Nebraska, Royce E. Ballinger, Steven M. Jones, J. W. Nietfeldt

Papers in Herpetology

Introduction: Studies of reptiles and amphibians in the grasslands of North America have primarily concerned the compilation of state faunal lists (e.g. Smith 1956, Hudson 1942, Webb 1970, Wheeler and Wheeler 1966). There have been a large number of reports on range extensions to augment this basic data. With the exception of the extensive studies by Fitch (1954, 1956, 1958, 1960, 1963) primarily on reptiles and Bragg (1940a, 1940b, 1943, 1953) primarily on anurans, the ecology of the herpetiles of the grasslands are not well studied. Lynch (1978) provided an excellent analysis of the ecological distributions of the leopard frogs …

A Comparison Of Reproductive Strategies Among Marine Snakes, Cliff A. Lemen, Harold K. Voris Apr 1981

A Comparison Of Reproductive Strategies Among Marine Snakes, Cliff A. Lemen, Harold K. Voris

School of Natural Resources: Faculty Publications

(1) Gravid females representing fourteen species of marine snakes were collected from four localities along the coast of Malaysia in 1975. The average clutch size ranged from 2.9 to 17.8 but most species had between three and seven young. The number of young produced and the size of gravid Lapemis hardwickii differed significantly at two sites in the Straits of Malacca. Eight species showed a significantly positive relationship between the number of oviducal eggs and female weight. The rate of infertility among ten species ranged from 4.5 to 20%.

(2) Sex ratios in the collections varied significantly through time and …


Review Of Deserts On The March By Paul B. Sears, R. Douglas Hurt Apr 1981

Review Of Deserts On The March By Paul B. Sears, R. Douglas Hurt

Great Plains Quarterly (through 2013)

In 1935, the worst Dust Bowl year, Paul B. Sears, then professor of botany at the University of Oklahoma, published Deserts on the March, a succinctly written book that directed public attention toward the growing menace of soil erosion in the United States. By 1980, Deserts on the March had become a classic ecological study; it is currently in the tenth printing and fourth edition. Sears, now retired from his position of chairman of the conservation program at Yale University, has rewritten much of the original text, but his message is the same today as it was nearly fifty …


Growth And Development Rates Of Microtus Pinetorum Under Different Photoperiods, T. L. Derting, J. A. Cransford Mar 1981

Growth And Development Rates Of Microtus Pinetorum Under Different Photoperiods, T. L. Derting, J. A. Cransford

Eastern Pine and Meadow Vole Symposia

Photo-period and nutrition are important variables affecting reproductive activity and growth in many rodents. Field and laboratory studies indicate that long photo-period (spring-summer) cause Increased growth while short photo-periods (fall-winter) inhibit these processes. In the montane vole (Microtus montanus) recently weaned animals gain weight at a much lower rate under short photo-periods or in total darkness than under long photo-periods (Vaughan et al., 1973; Peterborg, 1978). Adult M. montanus had more offspring and larger mean litter sizes under LD 18:6 than LD 6:18 (Pinter & Negus, 1965). Similarly, long (LD 16:8) or increasing photo-periods stimulated the onset of …

Missouri National Recreational River: Native American Cultural Resources, John Ludwickson, Donald Blakeslee, John O'Shea Jan 1981

Missouri National Recreational River: Native American Cultural Resources, John Ludwickson, Donald Blakeslee, John O'Shea

United States Army Corps of Engineers, Omaha District

An inventory of known and identifiable cultural resources referrable to Native American populations was undertaken for a corridor along the new Missouri National Recreational River, roughly from Gavin's Foint Dam to Ponca, Nebraska. These resources included archaeological sites and collections, ethnographic and ethnohistorical data and relevant environmental background information. Using these data the Native American occupation of the Missouri National Recreational River area was synthesized into a regional overview which stresses culture-historical developments and changing adaptations to the natural environment. Problems for continuing research utilizing existing archaeological collections were developed, and recommendations for continued field work to fill in gaps …


Comparative Water Relations And Photosynthesis Of Mycorrhizal And Non-Mycorrhizal Bouteloua Gracilis H.B.K. Lag Ex Steud., Michael F. Allen, William K. Smith, Thomas S. Moore Jr., Martha Christensen Jan 1981

Comparative Water Relations And Photosynthesis Of Mycorrhizal And Non-Mycorrhizal Bouteloua Gracilis H.B.K. Lag Ex Steud., Michael F. Allen, William K. Smith, Thomas S. Moore Jr., Martha Christensen

Department of Plant Pathology: Faculty Publications

The rangeland grass, Bouteloua gracilis was inoculated with its mycorrhizal symbiont, Glomus fasciculatus, to determine the influence of vesicular-arhuscular mycorrhizae on water status, stomatal behaviour and photosynthesis as well as gross plant morphology, biomass and phosphorus content. Mycorrhizal infection increased transpiration rates by over 100% with 50 to 70% lower leaf resistances to water vapour diffusion. Leaf xylem pressure was not different between mycorrhizal and non-mycorrhizal plants indicating that whole-plant resistance to water transport was reduced by more than 50%. Photosynthetic rates under saturating light conditions increased 68% with infection as a consequence of a 33% reduction in stomatal …

The Problem Of Pika Control In Baluchistan, Pakistan, Abdul Aziz Khan, William R. Smythe

Vertebrate Pest Conference Proceedings: 9th (1980)

The collared pika, Ochotona rufescens has been recorded as a serious pest in apple orchards in the uplands valley of Ziarat in Baluchistan. In the winter, when the natural vegetation is lacking, the pikas debark the apple tree trunks or branches resulting in the killing of the tree and reduced fruit production. In summer, damage to wheat, corn and potatoes is also very severe. It is estimated that pikas cause hundreds of thousands of dollars (US) in annual apple production losses. The apple production in Baluchistan accounts for about 35 percent of the total provincial income through food production. During …

Population Regulation In Wolves, Jane M. Packard, L. David Mech Jan 1980

Population Regulation In Wolves, Jane M. Packard, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The possibility of social regulation of wolf populations has been discussed in the literature for several years. Some of the first ecological studies of wolves indicated that their populations did not increase as rapidly as was theoretically possible, and that they reached a saturation point apparently not set by food. Subsequent captive studies demonstrated the existence of social mechanisms possibly capable of regulating population growth. However, the importance of these factors in wild populations has not been established. This paper has four objectives: (1) to evaluate the existing concept of "intrinsic limitation," (2) to propose that wolf population dynamics may …

Den And Den-Site Characteristics Of Coyotes (Canis Latrans) In Southeastern Nebraska, Donald P. Althoff Jan 1980

Den And Den-Site Characteristics Of Coyotes (Canis Latrans) In Southeastern Nebraska, Donald P. Althoff

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Sixteen pup-rearing den-sites of coyotes (Canis latrans) were located in southeastern Nebraska from 1976-1978. Although there was no selection for sites close to water or away from roads, dens were always located 400 m or farther from occupied farmsteads. The mean distance between neighboring dens was 3.87 km. Twelve sites were located within 1 m of brome grass (Bromus inermis); 15 dens were located where two cover-types met. Twelve dens were dug in loam soil; four in clay. Mean number of entrances for 10 excavated dens was 1.4, with the majority opening to the east and …


Floristic Analysis Of A Natural Area On The Lower Platte River Flood Plain, Donald A. Becker Jan 1980

Floristic Analysis Of A Natural Area On The Lower Platte River Flood Plain, Donald A. Becker

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The vascular flora of an extinct river-island and inactive northchannel of the Platte River was studied from 1972-1978. Within a variety of vegetation types, including seral and sub climax flood plain forests, 289 species were identified from 200 genera and 70 families. The flora is dominated by four families, the Poaceae, Asteraceae, Cyperaceae, and Fabaceae, which contribute 40% of the species. Forty-eight species of woody plants occur in the area, including 17 species not previously reported in Dodge County. While much of the flora is composed of forest species (36.1%), significant numbers of ruderal and marsh species (each 19.4%) are …

Cultural Ecology: A Brief Overview, Michael C. Gunn Jan 1980

Cultural Ecology: A Brief Overview, Michael C. Gunn

Nebraska Anthropologist

Cultural ecology is based on the interaction of culture, man and environment. To the understanding of this relationship the present paper discusses the origin and development of cultural ecology, the various applications and techniques of cultural ecology by the anthropological discipline, and finally, criticisms and future goals of an ecological anthropology.

Ecology is not an anthropological subdiscipline, nor is it even a standardized approach in anthropology. Ecology may be defined as the science dealing with the study of entire assemblages of living organisms and their physical milieus, which together constitute integrated systems. More simply, ecology is the study of the …

The Attractiveness Of Shredded Garbage To Gulls And Other Avian Species Potentially Hazardous To Aircraft, Dennis M. Forsythe Nov 1979

The Attractiveness Of Shredded Garbage To Gulls And Other Avian Species Potentially Hazardous To Aircraft, Dennis M. Forsythe

Bird Control Seminars Proceedings

The bird-aircraft strike hazard is a world-wide problem resulting in human fatalities and aircraft damage. Although the exact cost of bird damage is difficult to obtain, United States Air Force losses are estimated at over $10 million per year (Harrison 1976). Collisions between birds and aircrafts occur either enroute or when planes are landing or taking off at airports. Most of these collisions are due to large flocks of birds attracted to the vicinity by food, shelter, or water (Solman 1971). Solid waste disposal sites are an abundant food source for many hazardous bird species, especially gulls and blackbirds; and …

Water Usage And Power Production: The Electric Utility Industry Is Dependent On Water Utilization, T. P. Harding, L. G. Harrow Jan 1979

Water Usage And Power Production: The Electric Utility Industry Is Dependent On Water Utilization, T. P. Harding, L. G. Harrow

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The utilization of water as a heat transfer fluid is essential for the production of economic electrical power. There are many types of cooling facilities; however, the most economical means of electrical power production requires very large quantities of water to serve as a low temperature heat sink. For this reason, the power industry has, when possible, located its facilities near large sources of cold water, such as the Missouri River. The Omaha Public Power District (OPPD) has utilized the Missouri River since the turn of the century, and continues to do so today.

The availability of water in the …


Bacteriocin-Like Substances Produced By Rhizobium Japonicum And Other Slow-Growing Rhizobia, D. C. Gross, A. K. Vidaver Dec 1978

Bacteriocin-Like Substances Produced By Rhizobium Japonicum And Other Slow-Growing Rhizobia, D. C. Gross, A. K. Vidaver

Department of Plant Pathology: Faculty Publications

Bacteriocin-like substances were commonly produced by slow-growing Rhizobium japonicum and cowpea rhizobia on an L-arabinose medium. Antagonism between strains of R. japonicum was not detected in vitro; however, such strains were often sensitive to some bacteriocins produced by cowpea rhizobia. Inhibitory zones (2 to 8 mm from colony margins), produced by 58 of 66 R. japonicum test strains, were reproducibly detected with Corynebacterium nebraskense as an indicator. Quantitative production was not related to symbiotic properties of effective strains, since nine noninfective strains and one ineffective strain produced bacteriocin. Eight R. japonicum strains that did not produce bacteriocin nevertheless formed effective …
