University of Nebraska State Museum: Mammalogy Papers

An inventory of mammals in the vicinity of Brownsberg Nature Park, Suriname, incorporated a number of different sampling methods including examining museum voucher specimens, an animal-rescue operation, transect surveys, camera photo-traps, and interviews with local inhabitants. We document a total of 125 mammal species present in the Park. These include ten opossums, five pilosans, four armadillos, 58 bats, eight monkeys, 13 carnivores, one tapir, four artiodactyls, and 22 rodents. Nine of these species are reported for the first time from Suriname: one mouse opossum (Marmosops pinheiroi); one naked-backed moustached bat (Pteronotus gymnonotus); four fruit-eating bats ( …

Celastrina Serotina (Lycaenidae: Polyommatinae): A New Butterfly Species From The Northeastern United States And Eastern Canada, Harry Pavulaan, David M. Wright

The Taxonomic Report of the International Lepidoptera Survey

A new light-venter Azure species, Celastrina serotina, is described from the northeastern United States and eastern Canada. The flight period of this univoltine spring species is interpolated (allochrony) between its sympatric congeners, C. lucia Auctorum (not Kirby) and C. neglecta (Edwards). In this regard it is similar to C. neglectamajor Opler & Krizek in the southern Appalachians and C. idella Wright & Pavulaan on the New Jersey coastal plain. In a significant portion of its range, C. serotina larvae feed on eriophyid mite-formed galls on the upper surface of Black Cherry Prunus serotina Ehrh. …

Guide To Nebraska’S Wetlands And Their Conservation Needs: Second Edition, 2005, Ted Lagrange

Nebraska Game and Parks Commission: Publications

Wetlands — a source of great interest, and at times conflict. Wetlands represent different things to different people. At times they’re viewed as shallow, muddy nuisances while at other times they’re viewed as wonderful, varied and productive assets. This is because wetlands take on many roles as part of a complex and dynamic system. Understanding wetlands and wetland issues requires understanding the complex and varying roles that wetlands can play. To aid in this understanding, this guide defines wetlands, discusses their importance and dynamics, identifies threats and losses, describes conservation programs, and takes an in-depth look at Nebraska’s regional wetland …

Differences In Pah Tolerance Between Capitella Species: Underlying Biochemical Mechanisms, Lis Bach, Annemette Palmqvist, Lene Juel Rasmussen, Valery E. Forbes

Valery Forbes Publications

The polychaete Capitella capitata consists of a species complex within which differences in tolerance to tox­icants have been observed. For example, it has been shown that Capitella sp. S is more sensitive (e.g., in terms of survival, growth and reproduction) to PAH and other stressors than the more opportunistic Capi­tella sp. I, which is able to take up and biotransform the PAH fluoranthene (Flu). In the present study, an in­vestigation was performed to examine whether differences in tolerance between Capitella species sp. I and sp. S are due to differences in biotransformation, measured as the amount of Flu-metabolites produced by …

Ecology Of The Missouri River: Missouri River Creel Survey, Bellevue Bridge To Camp Creek, 3 April Through 29 May 2004, Gerald Mestl

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

The Nebraska Game and Parks Commission's strategic plan has stated the following management goal for the Missouri River: Restore, protect, and maintain the diversity of historic Missouri River habitats, resources, and ecosystem functions in order that present and future generations may enjoy consumptive and non-consumptive outdoor recreational opportunities (NGPC 1996). To accomplish this goal the Nebraska Game and Parks Commission identified the following five objectives: • To restore terrestrial and aquatic floodplain habitat types by 2008. This would include old oxbows, chutes, side channels, sand bars, backwaters, wetlands, and other shallow water habitats. To restore ftows that reflect the natural …

Taxonomic Analysis Of The Genus Megisto (Satyridae) In The Eastern United States, Part I: Types, Type Localities, And Taxonomic Relationships Of The Available Names, Ronald R. Gatrelle

The Taxonomic Report of the International Lepidoptera Survey

The genus Megisto Hübner, 1819 in the eastern United States and southeastern Canada is currently comprised of the original epithets Papilio eurytus Fabricius, 1775, Papilio cymela Cramer, 1777, Papilio eurytris, Fabricius, 1793, and Neonympha eurytris viola Maynard, 1891. Because the eastern Megisto is considered by some, including the present author, to contain two or more sibling species, the types and type localities of each of these names were studied. Where no type was found and no type locality fixed, typification was established by lectotypification or neotypification and a type locality was fixed. The taxonomic relationship of these taxa were …

Mammals Of The Cosigüina Peninsula Of Nicaragua, Hugh H. Genoways, Robert M. Timm

University of Nebraska State Museum: Mammalogy Papers

Nicaragua’s Cosigüina Peninsula, located at the northwestern tip of the country, is one of the most poorly studied biotic regions in Central America. The peninsula has been occupied for millennia because the climate of the region supported human habitation and because of its strategic position along the rich Pacific coast. The combination of long-term occupancy by humans and the cataclysmic eruptions of Volcán Cosigüina have produced a heavily impacted landscape. During the 1960s, the University of Kansas conducted multiyear field surveys of the terrestrial mammals on the peninsula and the adjacent mainland to quantify species diversity, relationships, abundances, habitat use, …

Availability Of Suitable Habitat For Northern River Otters In South Dakota, Alyssa M. Kiesow, Charles D. Dieter

Great Plains Research: A Journal of Natural and Social Sciences

Currently, the northern river otter (Lontra canadensis) is listed as a threatened species in South Dakota. We determined whether adequate habitat was available for reintroducing river otters in South Dakota. The 17 rivers/creeks included in the analysis were selected according to stream size, water gradient, and water permanence. A vegetation transect was conducted and a water sample was collected at each study site, ranging from one to four per river. Rivers/creeks were rated (1 = least suitable to 5 = most suitable) according to habitat requirements of river otters in the following categories: stream characteristics, watershed features, water …

Nebraska Catfish Anglers: Descriptions And Insights Derived From The 2002 Nebraska Licensed Angler Survey, Keith Hurley, Kristin Duppong-Hurley

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

Analyses in this report will refer to number of different groups. Catfish seeking anglers are defined as any angler who has spend at least 1 trip during 2002 in pursuit of a catfish species (channel, blue, flathead, or bullhead). This is the most general group included in the analyses and is also the least avid group of anglers in regards to their relationship to catfish angling. Catfish anglers are defined as those respondents who identified a catfish species as the species they most prefer to target. Catfish anglers represent a smaller group of respondents with a higher avidity for catfish …

Morbidity And Mortality Factors In Pre-Fledged Florida Sandhill Crane (Grus Canadensis Pratensis) Chicks, Robert J. Dusek, Marilyn G. Spalding, Donald J. Forrester, Nicholas Komar, Jonathan F. Day

Proceedings of the North American Crane Workshop

One hundred and fifteen Florida sandhill crane (Grus canadensis pratensis) chicks were captured in Osceola and Lake Counties, Florida in 1998 - 2000 and examined for evidence of disease. Evidence of Eimeria gruis and/or E. reichenowi infection was found in 52% of chicks examined. Ten chicks were positive for antibodies to St. Louis encephalitis virus and 1 of these chicks was also positive for antibodies to eastern equine encephalitis virus. Predation was the most commonly identified cause of mortality. An unidentified microfilaria, and an unknown protozoan were detected in blood smears from crane chicks. A number of other …

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 …

Patterns Of Habitat Use By Whooping Cranes During Migration: Summary From 1977–1999 Site Evaluation Data, Jane E. Austin, Amy L. Richert

Proceedings of the North American Crane Workshop

We used site evaluation data collected during 1977–1999 to examine patterns of habitat use by whooping cranes (Grus americana) during migration through the United States portion of the Wood Buffalo–Aransas flyway. We examined characteristics of 3 types of stopover habitats: 1) roost sites (n = 141 records), 2) feeding sites (n = 306), and 3) dual-use sites (i.e., where observer recorded cranes as using a site for both roosting and feeding (n = 248). Results in spring were influenced by the large number of records from Nebraska (> 67% of spring records) and in fall by frequent observations …

Philopatry And Dispersal In Whooping Cranes, Brian W. Johns, J. Paul Goossen, Ernie Kuyt, Lea Craig-Moore

Proceedings of the North American Crane Workshop

The natal and breeding dispersal of endangered whooping cranes (Grus americana) was investigated using information collected between 1978-2002 on the nesting grounds in and near Wood Buffalo National Park, Alberta-Northwest Territories. A minimum of 77% of the juveniles color-banded near their natal sites returned to the breeding grounds. Sex-biased natal dispersal was not observed. At least 76% of first-time breeders nested within 20 km of their natal site. Pioneering was rare and most cranes nested on the primary nesting areas adjacent to the Sass and Klewi rivers. The mechanism enhancing natal philopatry is probably related to learning the …

Capture Of Sandhill Cranes Using Alpha-Chloralose, Matthew A. Hayes, Barry K. Hartup, Jeanne Marie Pittman, Jeb A. Barzen

Proceedings of the North American Crane Workshop

From 1990 – 2001, 188 captures of 166 different greater sandhill cranes (Grus canadensis tabida) were made through the experimental use of alpha-chloralose (AC) in Wisconsin (Hayes et al., 2003). Captures occurred in August (n = 28, 15%), September (n = 136, 72%) and October (n = 24, 13%). Capture of all members in the target social group was relatively high (59%). Territorial pairs were captured more successfully (2 of 2 cranes were captured 69% of the time) than family groups (3 of 3 cranes were captured 50% of the time, and 4 of 4 cranes were captured …

Breeding Biology Of Re-Introduced Non-Migratory Whooping Cranes In Florida, Martin J. Folk, Stephen A. Nesbitt, Stephen T. Schwikert, James A. Schmidt, Kathleen A. Sullivan, Thomas J. Miller, Stephen B. Baynes, Jeannette M. Parker

Proceedings of the North American Crane Workshop

In the face of record-setting drought, the re-introduced flock of non-migratory whooping cranes in Florida has shown slow but steady progress toward achieving the first natural recruitment to the flock. Fourteen nests were initiated between 1999 and 2002. Two clutches have hatched a total of 4 chicks and 1 chick was raised to fledging. Captive-raised, soft-released whooping cranes have shown that they are capable of forming pair bonds, defending territories, building nests, laying fertile eggs, and hatching and rearing young. The key to the success of the project will be to have enough pairs producing enough young to offset annual …

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 …

An Obligation To Publish, Stephen A. Nesbitt

Proceedings of the North American Crane Workshop

To be justifiable any wildlife study should strive to attain and describe new knowledge or refine existing understanding. Published results of field studies are often the products that conclude the study, though not always. But, as E.O. Wilson wrote in Consiliance: The Unity of Knowledge, “One of the structures of the scientific ethos is that a discovery does not exist until it is safely reviewed and in print.” Putting knowledge to page requires effort and, frequently, the abandonment of ones own ego. However, ego notwithstanding, this is not the only reason to publish research findings. Whether we are trying to …

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 …

Head Stabilization In Whooping Cranes, Matthew R. Kinloch, Thomas W. Cronin, Glenn H. Olsen

Proceedings of the North American Crane Workshop

The whooping crane (Grus americana) is the tallest bird in North America, yet not much is known about its visual ecology. How these birds overcome their unusual height to identify, locate, track, and capture prey items is not well understood. There have been many studies on head and eye stabilization in large wading birds (herons and egrets), but the pattern of head movement and stabilization during foraging is unclear. Patterns of head movement and stabilization during walking were examined in whooping cranes at Patuxent Wildlife Research Center, Laurel, Maryland USA. Four whooping cranes (1 male and 3 females) …

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 …

Reintroduction Techniques: Post-Release Performance Of Sandhill Cranes (1) Released Into Wild Flocks And (2) Led On Migration By Ultralight Aircraft, Richard P. Urbanek, Joseph W. Duff, Scott R. Swengel, Lara E. A. Fondow

Proceedings of the North American Crane Workshop

Two methods of reintroducing a migratory population of whooping cranes (Grus americana) were tested with costume/ isolation-reared juvenile greater sandhill cranes (G. canadensis tabida): (1) release into wild flocks during autumn staging and (2) leading on autumn migration by ultralight aircraft. Birds in the first group were released singly, and all integrated quickly into the wild flocks and adopted similar behavioral patterns. Birds in the second group were led to winter on an inland site on the Gulf Coast of Florida. Most of the birds led by ultralight aircraft remained in their juvenile cohort through the …

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 …

Resolutions Passed By The North American Crane Working Group

Proceedings of the North American Crane Workshop

FRESHWATER INFLOWS FOR CONSERVATION OF BLUE CRABS AND WHOOPING CRANES Research has shown that whooping cranes require abundant blue crab populations on which to forage to meet their energy needs. The NACWG urges the Texas Council of Environmental Quality to grant a water right to the San Marcos River Foundation at the maximum level requested (1.15 million acre-feet) to provide freshwater inflows for conservation purposes as identified in a study conducted by the Texas Parks and Wildlife Department. These inflows would increase blue crab populations, keep the bays and marshes productive in whooping crane critical habitat at Aransas, and help …

Response Of Florida Sandhill Cranes To Nest Inspection, Stephen A. Nesbitt, Paul S. Kubilis, Stephen T. Schwikert

Proceedings of the North American Crane Workshop

We observed the response of nesting Florida sandhill cranes (Grus canadensis pratensis) to 27 instances of nest inspection. The disturbed bird flew from the area 81% and walked 19% of the time. The median distance moved was 330 meters (range 28 to 480 meters). The median length of time the nest was left unattended following inspection was 50 min (range: 10 to 166 min). The median length of time that observers stayed at the nest was 16 min (range: 5 to 48 min). Ten of the nests inspected (40%) eventually failed to produce young. Statistical analysis was focused …
