United States Geological Survey: Staff Publications
While conducting field work in Morton County, southwestern Kansas and Baca County, southeastern Colorado, during the period 27 May to 2 July 1997, we found 36 nests of seven bird species. Nests were not searched for systematically, but were found coincidentally as data were collected along transects during research investigating the breeding bird and plant communities of black-tailed prairie dog (Cynomys ludovicianus) colonies and noncolonized shortgrass prairie (Winter 1999).

Allometry, Sexual Size Dimorphism, And Niche Partitioning In The Mediterranean Gecko (Hemidactylus Turcicus), James B. Johnson, Lance D. Mcbrayer, Daniel Saenz
Faculty Publications
Hemidactylus tucrius is a small gekkonid lizard native to the Middle East and Asia that is known to exhibit sexual dimorphism in head size. Several potential explanations exist for the evolution and maintenance of sexual dimorphism in lizards. We tested 2 of these competing hypotheses concerning diet partitioning and differential growth. We found no differences in Average meal size (volume) or in any single dimension of prey size for similarly sized males and females. allometric patterns of increases in head size also were measured in males and females. We found that males exhibited a mixture of isometric and positively allometric …

Animal Science
Excess phosphorus (P) in manure is a major environmental pollutant associated with poultry and swine production and is directly related to eutrophication, which results in the death of aquatic organisms and loss of biodiversity. Phytate accounts for 50–80% of plant phosphorus and this phytate-bound P is unavailable to simple-stomached animals. As a result, this P is not utilized by the animal and is therefore excreted. Phytases are enzymes that cleave inorganic phosphate from phytic acid, thereby improving its bioavailability to simple-stomached animals. Strategies intended to limit levels of P excretion in production animals have included dietary supplementation of phytase, as …

This plan will guide management of wolves in Utah during an interim period from delisting until 2015, or until it is determined that wolves have established1 in Utah, or assumptions of the plan (political, social, biological, or legal) change. During this interim period, arriving wolves will be studied to determine where they are most likely to settle without conflict.
The goal of this plan is to manage, study, and conserve wolves moving into Utah while avoiding conflicts with the wildlife management objectives of the Ute Indian Tribe; preventing livestock depredation; and protecting the investment made in wildlife in Utah.
Analysis Of Genotypic And Phenotypic Differences In Desmognathus Quadramaculatus Across The Southern Appalachians, Deborah Susan Merritt
Analysis Of Genotypic And Phenotypic Differences In Desmognathus Quadramaculatus Across The Southern Appalachians, Deborah Susan Merritt
Theses, Dissertations and Capstones
Populations of Desmognathus quadramaculatus were compared for genotypic and phenotypic differences across 5 states in the Southern Appalachians. Series consisting of 10 salamanders each were collected from West Virginia, Virginia, Tennessee, North Carolina and Georgia. Salamanders were assessed for genotypic differences by using allozyme (proteins with polymorphic loci) electrophoresis staining for 13 loci of the muscle, liver and stomach tissue. Nei’s genetic distance was used to score genetic variation between populations. Phenotypic differences were assessed by comparing 10 external morphological measurements between populations. Mahalanobis’ distance was used to score morphological differences between populations. Both genetic and morphological differences were correlated …

Under the auspices of the Dakota Water Resources Act (DWRA) of 2000, the Secretary of the Interior has been directed to conduct a comprehensive study of the water quality and quantity needs of the Red River Valley and the options for meeting those needs. As such, the Bureau of Reclamation (Reclamation) requested technical support from the U.S. Geological Survey (USGS) Columbia Environmental Research Center (CERC) for an evaluation of the risks and economic consequences of biota transfers potentially associated with interbasin water transfers that might occur between the Upper Missouri River and the Red River of the North (Red River) …
Access And Allocation Arrangements For The Commercial 'Wetline' Fisheries. Proposals For Discussion., Commercial Access Panel
Access And Allocation Arrangements For The Commercial 'Wetline' Fisheries. Proposals For Discussion., Commercial Access Panel
Fisheries Management Papers
The Minister for Fisheries established this review of open access (wetline) commercial fishery arrangements to provide a more effective management framework for wetline fishing and to complement the recreational initiatives. This must involve the removal of excess fishing capacity, including latent effort, from the fishery and the establishment of a dedicated commercial fishery with clear entry criteria and an appropriate limit on catch in each bioregion. However it must be made clear that the ‘wetline review’ is not a sectoral resource sharing exercise. Following the implementation of new management arrangements for the ‘wetline’ fisheries, the appropriateness of the existing levels …

Prediction Of The Tenderness Of Cooked Poultry Pectoralis Major Muscles By Near-Infrared Reflectance Analysis Of Raw Meat, Bradley R. Cheatham
Prediction Of The Tenderness Of Cooked Poultry Pectoralis Major Muscles By Near-Infrared Reflectance Analysis Of Raw Meat, Bradley R. Cheatham
Inquiry: The University of Arkansas Undergraduate Research Journal
Tenderness in boneless poultry breast meat is of utmost importance to consumers. However, there is currently no nondestructive method to predict poultry breast meat tenderness. Textural properties of poultry breast meat were predicted by near-infrared reflectance (NIR) spectroscopy. Spectra were collected on 390 poultry Pectoralis major muscles from broiler carcasses to examine the correlation between NIR spectroscopy and the Meullenet-Owens Razor Shear (MORS) test. Two instrumental parameters (maximum shear force and total shear energy) were used as estimates of meat tenderness. Calibration (R2 cal) and validation (r2 val) coefficients of determination were used for predicting instrumental measurements using the reflectance, …
Use Of Wading Birds As Indicators Of Potential Whooping Crane Wintering Habitat, Dawn A. Sherry, Felipe Chavez-Ramirez
Use Of Wading Birds As Indicators Of Potential Whooping Crane Wintering Habitat, Dawn A. Sherry, Felipe Chavez-Ramirez
Proceedings of the North American Crane Workshop
A search for suitable wintering sites on which to establish another migratory population of whooping crane (Grus americana) has been conducted and will continue. In addition to an evaluation of food availability for whooping cranes, wading birds that overlap highly in patterns of habitat utilization with whooping cranes may be useful as indirect indicators of suitable whooping crane habitat. We determined the extent to which several species of wading birds overlap in patterns of habitat utilization with whooping cranes on their current wintering grounds. We conducted aerial surveys of whooping cranes and wading birds at Aransas and Matagorda …
Patterns Of Relationships Among Whooping Crane Fitness, Blue Crab Abundance, And Freshwater Inflows: An Exploratory Assessment Of Available Data Sets, Felipe Chavez-Ramirez
Patterns Of Relationships Among Whooping Crane Fitness, Blue Crab Abundance, And Freshwater Inflows: An Exploratory Assessment Of Available Data Sets, Felipe Chavez-Ramirez
Proceedings of the North American Crane Workshop
This paper evaluates the possible relationships of whooping crane (Grus americana) fitness parameters to blue crab abundance and freshwater inflows based on independently gathered data sets from several agencies between 1978 and 1999. I ordered all possible analysis models into two separate types based primarily on implied relationships. The 1st order exploratory relationship models were those where evaluated parameters were potentially affected by freshwater inflows, such as salinity and blue crab abundance. The 2nd order exploratory relationship models evaluated parameters that could, more directly, have potential affects on whooping crane fitness parameters for which there was data available. Freshwater inflow …
Do Arctic-Nesting Geese Compete With Sandhill Cranes For Waste Corn In The Central Platte River Valley, Nebraska?, Gary L. Krapu, David A. Brandt, Robert R. Cox Jr.
Do Arctic-Nesting Geese Compete With Sandhill Cranes For Waste Corn In The Central Platte River Valley, Nebraska?, Gary L. Krapu, David A. Brandt, Robert R. Cox Jr.
Proceedings of the North American Crane Workshop
Numbers of arctic-nesting geese staging in spring in the Central Platte River Valley (CPRV) of southcentral Nebraska increased dramatically from the 1970s to the 1990s, raising concerns that geese may be competing with the mid-continental population of sandhill cranes (Grus canadensis) for waste corn. From late February to mid-April 1998-2001, we measured temporal patterns of cropland use, evaluated habitat preferences, and compared numbers of geese using the primary crane-occupied parts of the CPRV area with numbers of sandhill cranes. Numbers of Canada geese (Branta canadensis), lesser snow geese (Chen caerulescens)/ Ross’ geese (Chen …

Greater Sandhill Crane: Research And Management In California Since 1978, Ronald W. Schlorff
Proceedings of the North American Crane Workshop
The greater sandhill crane (Grus canadensis tabida) was added to the California list of threatened species in 1983, and the subspecies has been the subject of research and management actions instituted by the California Department of Fish and Game (hereafter Department). Since 1978, the Department has conducted research and recovery actions including periodic breeding ground and wintering area studies, population monitoring, participated in developing Pacific Flyway crane management plans, acquisition and management of key habitats on breeding and wintering grounds, and developed a draft greater sandhill crane recovery strategy. These tasks were accomplished with the assistance of crane …
Historical Notes On Whooping Cranes At White Lake, Louisiana: The John J. Lynch Interviews, 1947–1948, Gay M. Gomez, Roderick C. Drewien, Mary Lynch Courville
Historical Notes On Whooping Cranes At White Lake, Louisiana: The John J. Lynch Interviews, 1947–1948, Gay M. Gomez, Roderick C. Drewien, Mary Lynch Courville
Proceedings of the North American Crane Workshop
In May 1939 biologist John J. Lynch of the U.S. Bureau of Biological Survey conducted an aerial survey that documented the existence of a non-migratory population of whooping cranes (Grus americana) near White Lake in southwest Louisiana. Lynch found 13 cranes, including 2 pre-fledged young, confirming breeding. Lynch’s survey occurred, in part, because fur trappers and alligator hunters working in the White Lake marshes had informed the biologist of the cranes’ presence and habits. Lynch continued his contacts with these knowledgeable marsh users, and in 1947 and 1948 interviewed at least 7 individuals. In 2001, M. L. Courville, …

Whooping Crane Titers To Eastern Equine Encephalitis Vaccinations, Glenn H. Olsen, Erin Kolski, Jeff S. Hatfield, Douglas E. Docherty
Proceedings of the North American Crane Workshop
In 1984 an epizootic of eastern equine encephalitis (EEE) virus killed 7 of 39 (18%) whooping cranes in captivity at the Patuxent Wildlife Research Center in Laurel, Maryland, USA. Since that time whooping cranes have been vaccinated with a human EEE vaccine. This vaccine was unavailable for several years, necessitating use of an equine vaccine in the cranes. This study compared the antibody titers measured for three years using the human vaccine with those measured for two years using the equine form. Whooping cranes developed similarly elevated titers in one year using the human vaccine and both years using the …
Age, Sex, And Aggression In Florida Sandhill Cranes, Stephen A. Nesbitt
Age, Sex, And Aggression In Florida Sandhill Cranes, Stephen A. Nesbitt
Proceedings of the North American Crane Workshop
Individually directed aggressive interactions were recorded for sandhill cranes in Florida over a 9-year period. Charges and stabs were the most frequently observed aggressive behaviors. Paired adults initiated most of the encounters. Males directed 67% of aggressive interactions toward other males and 84% of female aggressive interactions were directed toward other females. The sex of initiator was significantly correlated with the sex of the receiver (P = 0.001). Paired adults directed most aggression (64.7%) toward other paired adults. Aggression initiated by subadult cranes was directed toward adults and subadults with equal frequency. The aggressiveness in males as an indicator of …
The Status Of The Common Crane (Grus Grus) In Europe: Breeding, Resting, Migration, Wintering, And Protection, Hartwig Prange
The Status Of The Common Crane (Grus Grus) In Europe: Breeding, Resting, Migration, Wintering, And Protection, Hartwig Prange
Proceedings of the North American Crane Workshop
At present, about 160,000 and 100,000 cranes are migrating on the West-European and on the Baltic-Hungarian routes, respectively, from the northern, middle, and northeastern parts of Europe. On both routes, the resting maxima, simultaneously determined since the 1980’s, has increased three-fold. This increase in migratory cranes is the result of shorter migration routes with higher return rates, a growing passage from the northwestern part of Russia beginning in the 1990’s, and a protected status in the European Union at breeding as well as at many resting and wintering sites. Hence, the cranes learn to find and use new breeding and …

Crop Depredations By Cranes At Daursky State Biosphere Reserve, Siberia, Stephen H. Bouffard, John E. Cornely, Oleg A. Goroshko
Crop Depredations By Cranes At Daursky State Biosphere Reserve, Siberia, Stephen H. Bouffard, John E. Cornely, Oleg A. Goroshko
Proceedings of the North American Crane Workshop
Crop depredations by staging cranes have been an annual problem at Daursky State Biosphere Reserve in southern Siberia. In September 2001 we met at Daursky when crane populations peaked to investigate the problem and suggest methods to reduce damages. Peak of crane staging coincided with grain harvest. We counted ≈ 30,000 cranes of 5 species, primarily demoiselles (Anthropoides virgo), in the area. Poor grain yields and cooperative farming systems discouraged efforts to reduce damage. Moving crops further from roost areas may be the most reasonable short term control method, but it’s effectiveness is yet untested. Hazing, lure crops …

First Cohort Of Migratory Whooping Cranes Reintroduced To Eastern North America: The First Year After Release, Richard P. Urbanek, Lara E. A. Fondow, Colleen D. Satyshur, Anne E. Lacy, Sara E. Zimorski, Marianne Wellington
Proceedings of the North American Crane Workshop
We describe the post-release movements and survival of the first cohort in the eastern migratory whooping crane (Grus americana) reintroduction from release the first winter through return the second winter. Six cranes were led behind ultralight aircraft from Necedah National Wildlife Refuge (NWR), Central Wisconsin, to Chassahowitzka NWR, Gulf Coast of Florida. After release in Florida, 1 of these cranes and another transported there by truck were killed by bobcats (Lynx rufus). The winter management protocol was modified and no further predation occurred. The 5 remaining cranes migrated unassisted back to Necedah NWR in spring, left …
Sandhill Crane Mortality During Fall Migration Stopover In North-Central New Mexico, Fall 2001, William Deragon, Wendy Brown, Gail Garber, Mike Richard
Sandhill Crane Mortality During Fall Migration Stopover In North-Central New Mexico, Fall 2001, William Deragon, Wendy Brown, Gail Garber, Mike Richard
Proceedings of the North American Crane Workshop
Seventy-three Rocky Mountain greater sandhill cranes died after being mired in mud at a traditional migration stopover site during a fall migration 2001. Drawdown of the Jemez Canyon Dam reservoir in New Mexico resulted in over 200 acres of deep saturated silt and clay into which sandhill cranes became entrapped. Harassment to discourage birds from landing in the area was implemented immediately and partially successful. Rescue efforts were delayed because of an inability to safely access the cranes in these conditions. After 9 days, the use of a specialized 20-horsepower motor mounted on a small aluminum boat was employed. Seventeen …
Impact Of Management Changes At An Autumn Greater Sandhill Crane Staging Area In Oregon, Carrol D. Littlefield
Impact Of Management Changes At An Autumn Greater Sandhill Crane Staging Area In Oregon, Carrol D. Littlefield
Proceedings of the North American Crane Workshop
Malheur National Wildlife Refuge, Oregon was the most important autumn staging area for greater sandhill cranes (Grus canadensis tabida) in the northwest Pacific coastal states. During 1983-88, changes in management including increases in human disturbance and habitat alterations resulted in significant declines in autumn crane use. Compared with the period 1975-82, mean annual autumn crane peak numbers declined from 2,454 to 1,352, whereas mean biweekly numbers declined from 791 to 353. Management changes included roost site drying and flooding of a primary feeding area; disturbance factors included cattle herding through a loafing site and dump trucks traveling through …
A Fresh Look At The Taxonomy Of Midcontinental Sandhill Cranes, Douglas H. Johnson, Jane E. Autin, Jill A. Shaffer
A Fresh Look At The Taxonomy Of Midcontinental Sandhill Cranes, Douglas H. Johnson, Jane E. Autin, Jill A. Shaffer
Proceedings of the North American Crane Workshop
The midcontinental population of sandhill crane (Grus canadensis) includes about 500,000 birds and provides valuable recreational crane-watching and hunting opportunities in Canada and the United States. It comprises three subspecies, one of which (G. c. rowani) was of uncertain taxonomic status and another of which (G. c. tabida) merited protection from excessive harvest due to its small population size. We obtained measurements of cranes used by Johnson and Stewart (1973) and additional crane specimens to 1) evaluate the subspecies designation of midcontinental sandhill cranes and 2) to seek improved methods for classifying cranes from …
