The Utility Of Census Or Survey For Monitoring Whooping Cranes In Winter, Bruce H. Pugesek, Thomas V. Stehn

Proceedings of the North American Crane Workshop

We discuss recent changes in the monitoring program for endangered whooping cranes (Grus americana) on their winter habitat in Texas. A 61-year annual census was replaced in the winter of 2011-2012 with a distance sampling procedure. Justification for the change was, in part, based on criticism of the previous methods of counting cranes and the assessment of crane mortality on the wintering grounds. We argue here that the arguments, methods, and analyses employed to discount the census procedure and mortality estimates were applied incorrectly or with flawed logic and assertions. We provide analysis and logical arguments to show …

Protocol And Results From The First Season Of Captive-Rearing Whooping Cranes For A Non-Migratory Release In Louisiana, Glenn H. Olsen, Jane N. Chandler

Proceedings of the North American Crane Workshop

The principal historic range of the whooping crane (Grus americana) consisted of the tall grass prairies and wetlands of southwest Louisiana, Texas, and parts of Mexico (Allen 1952). Whooping cranes migrated there from Illinois, Iowa, Minnesota, Dakotas, Manitoba, Saskatchewan, Alberta, and breeding grounds of the remnant flock in and near Wood Buffalo National Park, Canada.

Habitat Selection By Breeding Sandhill Cranes In Central Wisconsin, Tamara P. Miller, Jeb A. Barzen

Proceedings of the North American Crane Workshop

We used compositional analysis to describe habitat use for a dense population of breeding sandhill cranes (Grus canadensis tabida) in central Wisconsin at 2 spatial scales: selection of home range within a study area and selection of habitats within the home range. Habitat use and home range size were estimated from radio-telemetry data from 12 breeding sandhill crane pairs. Research in Wisconsin that was performed on the landscape level suggests that breeding cranes depend on wetlands and do not select upland habitats. Evaluating habitat selection at different spatial levels, such as during different stages of the breeding season, …

Historic And Recent Winter Sandhill Crane Distribution In California, Gary L. Ivey, Caroline P. Herziger, David A. Hardt, Gregory H. Golet

Proceedings of the North American Crane Workshop

Understanding the geographic distribution and long-term dynamics of winter foraging areas and night roost sites of sandhill cranes (Grus canadensis) is important to their conservation and management. We studied sandhill crane distribution in California’s Central Valley from December 2012 through February 2013. We mapped observed flock and night roost locations. Flock locations occurred between Tehama County in the north and Kern County in the south. Flocks were concentrated in the northern Sacramento Valley, the Sacramento-San Joaquin Delta, the northern San Joaquin Valley south of Tracy to Mendota (including the lower Stanislaus and Tuolumne River floodplains and the Grasslands …

A Review Of Fall Sandhill Crane Migration Through Indiana, Allisyn-Marie T. Y. Gillet

Proceedings of the North American Crane Workshop

The Indiana Division of Fish and Wildlife conducts surveys from October to December to collect long-term data on greater sandhill cranes (Grus canadensis tabida). Results from these censuses contribute to a fall index of the Eastern Population, which informs wildlife management decisions and research priorities. Recent findings from the annual U. S. Fish and Wildlife Service Fall Sandhill Crane Migration Survey demonstrate a decline in the number of cranes observed at fall staging areas throughout Indiana since 1979. However, nationwide data exhibit a trend of population increase. I provide evidence to show that the apparent decline in the …

What Does Motivated Mean? Re-Presenting Learning, Technology, And Motivation In Middle Schools Via New Ethnographic Writing, Justin Olmanson

Department of Teaching, Learning, and Teacher Education: Faculty Publications

This article offers a critique of the way middle schoolers are often positioned as generalizable objects that can be acted upon to produce measurable increases in motivation and learning. The critique invites a reconsideration and cultural analysis of some of the dominant discourses and perceptions of technology, young adolescence, and the study of motivation. The use of New Ethnographic Writing—a method that performs a cultural critique via extended scenes—connects to the roles and status of motivation, technology, and educational research methods deployed within public schools. Coupled with weak theory, this approach offers a way to understand young adolescents as navigating …

Light Goose Conservation Order Effects On Nontarget Waterfowl Behavior And Energy Expenditure, Andrew J. Dinges, Elisabeth B. Webb, Mark P. Vrtiska

Nebraska Game and Parks Commission: Staff Research Publications

When the Light Goose Conservation Order (LGCO) was established during 1999 in the Rainwater Basin of Nebraska, USA, LGCO activities were limited to 4 days/week and 16 public wetlands were closed to the LGCO to limit disturbance to non-target waterfowl during this energetically important time period. However, the effects of LGCO activities on waterfowl behavior and energy expenditure are relatively unknown in this critical waterfowl staging area. To evaluate LGCO effects on target and nontarget species, we paired wetlands open and closed to LGCO and recorded waterfowl behavior and hunter encounters during springs 2011 and 2012. We constructed hourly energy …

Status Review Of The Black-Billed Magpie (Pica Hudsonia) In Nebraska, Joel G. Jorgensen

Nebraska Game and Parks Commission: Staff Research Publications

The Black-billed Magpie (Pica hudsonia) is a conspicuous and easily-identifiable member of the corvid family (Corvidae) that inhabits open country. In Nebraska, Black-billed Magpies have apparently declined in recent years and are now no longer found in many areas of their former range (Mollhoff 2013). I conducted a literature and data review of existing resources and, here, I summarize the status of the Black-billed Magpie over time, with emphasis on changes in distribution and abundance over time. The document is focused on Nebraska, but some information and analyses from nearby states is included to provide a broader context. I …

Whooping Crane (Grus Americana) Behavior, Habitat Use And Wildlife Watching Visitation During Migratory Stopover At Two Wildlife Management Areas In Nebraska 2015-2016, Joel G. Jorgensen, Lauren R. Dinan

Nebraska Game and Parks Commission: Staff Research Publications

The Whooping Crane (Grus americana) is one of the rarest bird species in the world (Harrell and Bidwell 2013). Whooping Cranes are listed as endangered by the United States and Canada under their respective Endangered Species Acts (CWS and USFWS 2007) and by the Nebraska Nongame and Endangered Species Conservation Act. Whooping Crane numbers in the Aransas-Wood Buffalo (AWB) flock, the only self-sustaining wild population, were estimated to be as low as 14 adults and 4 juveniles during the winter of 1938-1939 (CWS and USFWS 2007). During the winter of 2014-2015, the estimated size of the AWB flock was …

Addendum To Encomia And Reflections, Clyde Jones (1935-2015): Encomium, Robert J. Baker, Carleton J. Phillips, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

This is the authors' collective attempt to provide an encomium (an honest song of praise) for Clyde Jones. After some urging from the editors of this volume, the authors conspired to share some memories of Clyde.

Editors’ note: Due to various factors, this encomium was submitted too late to be included in the published memorial volume. However, in consideration of the relationship of the authors to Clyde Jones, we agreed to make this encomium available via electronic format as a supplement to the printed volume.

Veiled In Ignorance And Clothed In Reason: Jimmie Durham’S 2014 Exhibition Traces And Shiny Evidence, Andrea Feeser

Textile Society of America: Symposium Proceedings

In the 2014 London exhibition “Traces and Shiny Evidence,” Jimmie Durham showed on one floor brightly colored oil barrels, car parts, pcv pipes, and reproduction animal skeletons covered with or leaking ooze that shimmered with rainbow hues. On a floor one level up, Durham exhibited wall size drawing-prints he made by throwing stuffed animals coated with charcoal at very large pieces of paper. In the video that recorded Durham making the drawing-prints, the artist wears a workman’s vest labeled “Steiner. Maison de la Paix.” A video that is featured in the exhibition itself shows Durham in a business suit seated …

Recovery Rates Of Bottlenose Dolphin (Tursiops Truncatus) Carcasses Estimated From Stranding And Survival Rate Data, James V. Carretta, Kerri Danil, Susan J. Chivers, David W. Weller, David S.

Recovery of cetacean carcasses provides data on levels of human-caused mortality, but represents only a minimum count of impacts. Counts of stranded carcasses are negatively biased by factors that include at-sea scavenging, sinking, drift away from land, stranding in locations where detection is unlikely, and natural removal from beaches due to wave and tidal action prior to detection. We estimate the fraction of carcasses recovered for a population of coastal bottlenose dolphins (Tursiops truncatus), using abundance and survival rate data to estimate annual deaths in the population. Observed stranding numbers are compared to expected deaths to estimate the …

Wildfire May Increase Habitat Quality For Spring Chinook Salmon In The Wenatchee River Subbasin, Wa, Usa, Rebecca L. Flitcroft, Jeffrey A. Falke, Gordon H. Reeves, Paul F. Hessburg, Kris M. Mcnyset, Lee E. Benda

United States Department of Commerce: Staff Publications

Pacific Northwest salmonids are adapted to natural disturbance regimes that create dynamic habitat patterns over space and through time. However, human land use, particularly long-term fire suppression, has altered the intensity and frequency of wildfire in forested upland and riparian areas. To examine the potential impacts of wildfire on aquatic systems, we developed stream-reach-scale models of freshwater habitat for three life stages (adult, egg/fry, and juvenile) of spring Chinook salmon (Oncorhynchus tshawytscha) in the Wenatchee River subbasin, Washington. We used variables representing pre- and post-fire habitat conditions and employed novel techniques to capture changes in in-stream fine sediment, …

Methods For Sampling Sequential Annual Bone Growth Layers For Stable Isotope Analysis, Calandra N. Turner Tomaszewicz, Jeffrey A. Seminoff, Larisa Avens, Carolyn M. Kurle

United States Department of Commerce: Staff Publications

1. Stable carbon (§¹³C) and nitrogen (§¹⁵N) isotope analysis (SIA) has proven useful in addressing fundamental questions in ecology such as reconstructing trophic interactions, habitat connections and climate regime shifts. The temporal scales over which SIA can be used to address ecological problems vary depending on the protein turnover times of the analysed tissue. Hard, inert tissues, such as teeth, bones and mollusc shells, grow in regular intervals (i.e. daily or annually), and sequential sampling of these growth layers provides a time series of isotopic patterns. As a result, SIA on these tissues is useful for …

IndiSeas (“Indicators for the Seas”) is a collaborative international working group that was established in2005 to evaluate the status of exploited marine ecosystems using a suite of indicators in a comparative framework. An initial shortlist of seven ecological indicators was selected to quantify the effects of fishing on the broader ecosystem using several criteria (i.e., ecological meaning, sensitivity to fishing, data avail-ability, management objectives and public awareness). The suite comprised: (i) the inverse coefficient of variation of total biomass of surveyed species, (ii) mean fish length in the surveyed community, (iii)mean maximum life span of surveyed fish species, (iv) proportion …

Invasibility Of Three Major Non-Native Invasive Shrubs And Associated Factors In Upper Midwest U.S. Forest Lands, W. Keith Moser, Zhaofei Fan, Mark H. Hansen, Michael K. Crosby, Shirley X. Fan

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

We used non-native invasive plant data from the United States Forest Service’s Forest Inventory and Analysis (FIA) program, spatial statistical methods, and the space (cover class)-for-time approach to quantify the invasion potential and success (‘‘invasibility”) of three major invasive shrubs (multiflora rose, non-native bush honeysuckles, and common buckthorn) in broadly classified forest-type groups in seven Upper Midwest states. Smoothed maps of presence and cover percent showed a strong clustering pattern for all three invasive shrubs despite their different ranges. The species are clustered around major cities or urban areas (e.g., Chicago, Illinois, and Des Moines, Iowa), indicating the potential role …
