Lissodelphis Peroni, Michael W. Newcomer, Thomas A. Jefferson, Robert L. Brownell Jr.

United States Department of Commerce: Staff Publications

Order Cetacea, Suborder Odontoceti, Family Delphinidae. The subfamily Lissodelphinae has been proposed for this genus (Fraser and Purves, 1960), but it has not been universally accepted (Kasuya, 1973). There are two species in the genus: Lissodelphis peronii (southern right whale dolphin) and L. borealis (northern right whale dolphin). Lissodelphis peronii currently contains no subspecies.

Histomorphological Responses Of Red Shiner (Cyprinella Lutrensis) To Atrazine, Terbufos, And Their Mixture, Ibrahim A. Messaad

School of Natural Resources: Dissertations, Theses, and Student Research

Alterations of normal histomorphology of fish tissues, behavior, and thermal tolerance are recognized by environmental toxicologists and fish biologists as powerful tools indicating diverse biochemical and physiological changes. Toxicity of atrazine (2-chloro-4-ethylamino-6-isopropylamino-1,3,5-triazine), terbufos (S-(((1,1-dimethyl-ethyl)thio)methyl)O,O-diethyl phosphorodithioate), and their mixture to red shiner (Cyprinella lutrensis) at 23$\sp\circ$C and 30$\sp\circ$C was investigated in 14-d bioassays after 14-d acclimation. During the bioassays, fish behavior, indications of toxicosis, and external anomalies were observed. After the bioassays, the critical thermal maximum (CTM) was determined. Fish also were preserved for examinations of gill, liver, and kidney tissues using scanning electron microscopy (SEM) and light microscopy (LM). SEM …

Assessment Of The Status Of Harbor Porpoise (Phocoena Phocoena) In Oregon And Washington Waters, S. Osmek, J. Calambokidis, J. Laake, P. Gearin, R. Delong, J. Scordino, S. Jeffries, R. Brown

United States Department of Commerce: Staff Publications

The status of harbor porpoise, Phocoena phocoena, is reviewed for stocks in Oregon and Washington waters, and the adjacent transboundary waters of southern British Columbia, Canada, emphasizing the most recent data on their geographic range, population structure, distribution, population size, trends in abundance, and reproductive biology. This information is used to determine if the annual rate of incidental mortality and serious injury in gill-net fisheries from 1990-94 could be at a biologically significant level.

In the eastern North Pacific Ocean, harbor porpoise are found near the coast, generally in water depths of less than 200 m. Differences in harbor porpoise …

Prairie Legacies - Mammals, Russell A. Benedict, Patricia W. Freeman, Hugh H. Genoways

School of Natural Resources: Faculty Publications

Few North American ecosystems have been as dramatically altered by humans as the prairies of the Great Plains. Occupying the immense interior of North America, these deceiving grassland oceans hid their complexity and diversity from many early travelers who saw this area merely as an obstacle to overcome in their westward journeys. But for the careful observer, prairies hold a tremendous quantity of life, arranged in a diverse mosaic of patches ranging in scale from minute anthills to the vastness of the Nebraska Sandhills or Kansas Flint Hills. Not only is a given ridgetop subdivided into a number of areas …

Age Classification Of Laughing Gulls Based On Summer Plumage, Jerrold L. Belant, Richard A. Dolbeer

USDA Wildlife Services: Staff Publications

We described quantitatively 19 summer plumage characteristics and bill and foot pigmentation of 247 known-age Laughing Gulls (Larus atricilla) collected in New York during 1992-1994. There were no differences in characteristics measured for male and female Laughing Gulls. Ninety percent of 2-yr-old Laughing Gulls and 96% of ≥ 3-yr-old birds had full hoods. Fifty-seven percent of 2-yr-old Laughing Gulls possessed at least partial tail bands in contrast to 4% of 3-yr-old and 0% of ≥ 4-yr-old gulls. Thus 2-and ≥ 3-yr-old Laughing Gulls cannot be separated reliably by the presence or absence of a tail band. Pink pigmentation on the …

Review Of Planting The Future: Developing An Agriculture That Sustains Land And Community Edited By Elizabeth A. R. Bird, Gordon L. Bultena, And John C. Gardner, Charles A. Francis

Great Plains Research: A Journal of Natural and Social Sciences

Why should you care about agriculture? Planting the Future provides an eloquent description of the current state of this' most basic human endeavor so critical to survival. Based on a series of surveys and on-farm studies in the North Central and Western states, the book recognizes the bounty of our conventional agricultural industry. More importantly for the future, it details a series of critical problems in the environment, the distribution of economic benefits, and the social dislocation resulting from the consolidation of lands and heavy reliance on fossil fuels. Today's productivity and cheap food in the market have hidden expenses …

Reproductive Success Of Grasshopper Sparrows In Relation To Edge, Jennifer M. Delisle, Julie A. Savidge

School of Natural Resources: Faculty Publications

Using an index based on observations of breeding behaviors, we estimated reproductive success of 31 territorial grasshopper sparrows (Ammodramus savannarum) on Conservation Reserve Program fields in southeast Nebraska. Reproductive success was 52%, and no difference was detected between birds holding interior (>100 m from the edge) vs. edge territories. However, grasshopper sparrows appeared to avoid nesting within 50 m of edge habitats. Territories ranged from 0.36-1.24 ha, and territory size did not differ between successful and unsuccessful males.

Distribution And Abundance Of Roof-Nesting Gulls In The Great Lakes Region Of The United States, Chris P. Dwyer, Jerrod L. Belant, Richard A. Dolbeer

USDA Wildlife Services: Staff Publications

In 1994, we conducted aerial, mail, and telephone surveys to determine the distribution and abundance of roof-nesting gulls in states bordering the Great Lakes. We documented more than 7,922 nesting pairs of gulls at 30 colonies in four states; species composition was 71% ring-billed (Larus delawarensis^, 24% herring (Z. argentatus^, and 5% unknown. Colony size ranged from 1 to 1,003 nesting pairs. Proportions of ring-billed gulls nesting less that 5.0 and more than 10.0 km from the Great Lakes were 31% and 39%, in contrast to 63% and less than 1% for herring gulls, respectively. Maximum distances herring and ring-billed …

Improving The Validation Of Model-Simulated Crop Yield Response To Climate Change: An Application To The Epic Model* Jour. Ser. No. 11339 Nebraska Ag. Res. Div., William E. Easterling, Xiafen Chen, Cynthia Hays, James R, Brandle, Hehui Zang

School of Natural Resources: Faculty Publications

Crop models have been used extensively to simulate yield response to various scenarios of climate change. Such simulations have been inadequately validated, limiting their utility in policy analysis. In this research, it is argued that the performance of crop models during recent years of extreme weather conditions relative to current normals may give a better indication of the validity of model simulations of crop yields in response to climate change than performance during the full range of climate conditions (as is done now). Twenty years of the climate record (1971-1990) are separated into different growing season temperature and precipitation classes …

Extension Wetlands Education In Texas, Darrin Bauer, Will E. Cohen

8th Triennial National Wildlife and Fisheries Extension Specialists Conference (1996)

The United States has lost more than half of the wetlands that existed prior to European settlement. Wetlands continue to be lost at an alarming rate due to human disturbance and natural processes. The loss of our countries' wetlands is costing our society greatly. Wetlands perform many functions that are beneficial, such as water filtration, recharging groundwater, providing natural flood control, and supporting a wide variety of birds, fish, mammals, amphibians, insects, and plants. Numerous commercially important fish also require wetlands to survive. Wetlands also provide many recreational opportunities.

Expectations And Future Opportunities For Fish And Wildlife Extension Programs, Jack H. Berryman

The charge to the panel was really in the form of a question: What do customers and cooperators expect and what are the future opportunities for fish and wildlife extension programs?

It's a pretty risky subject. Each state is different; each has different problems and opportunities. And, most of the practitioners—those who know most about it— are here in this audience.

Pete Petoskey and Jim Miller have already presented some historical background and a perspective for the future. And, the fact of these workshops and a glance at the program is clear evidence of the progress being made. The professionalism, …
