The Benthic Community Of The Eastern Us Continental Shelf: A Literature Synopsis Of Benthic Faunal Resources, R. Allen Brooks, Carla N. Purdy, Susan S. Bell, Kenneth J. Sulak

United States Geological Survey: Staff Publications

The existing scientific literature on offshore benthic assemblages (OBA) residing along the US East and Gulf of Mexico continental shelf was reviewed. Identification was made of any associations between the dominant OBA and particular sediment types and/or bathymetry. Of special interest was the evaluation of reported effects of sand dredge/mining activities on the dominant OBA and recognition of data deficiencies. One hundred and twenty-two references were selected and classified as to type of study with pertinent results extracted. Polychaetes were predominantly cited as the principal infaunal taxa present in studies from both the Gulf of Mexico and US Atlantic coast. …

Attitudes Of Rural Landowners Toward Wolves In Northwestern Minnesota, Andreas S. Chavez, Eric M. Gese, Richard S. Krannich

United States Department of Agriculture Wildlife Services: Staff Publications

The natural recolonization of gray wolves (Canis lupus) into parts of their former range in the upper Midwest of the United States has led to wolves establishing territories in semi-agricultural areas containing livestock. As part of a study on wolf–livestock relationships in a northwestern Minnesota agricultural area, we surveyed rural landowners within and outside of wolf range to assess perceptions regarding the risks wolves pose to livestock (mainly cattle). The mean response score for rural landowners to the statement “I think wolves should be allowed to exist in northwest Minnesota” was between neutral and disagree. There was no …

Optimizing Allocation Of Monitoring Effort Under Economic And Observational Constraints, Scott A. Field, Andrew J. Tyre, Hugh P. Possingham

School of Natural Resources: Faculty Publications

Efforts to design monitoring regimes capable of detecting population trends can be thwarted by observational and economic constraints inherent to most biological surveys. Ensuring that limited resources are allocated efficiently requires evaluation of statistical power for alternative survey designs. We simulated the process of data collection on a landscape, where we initiated declines over 3 sample periods in species of varying prevalence and detectability. Changing occupancy levels were estimated using a technique that accounted for effects of false-negative errors on survey data. Declines were identified within a frequentist statistical framework, but the significance level was set at an optimal level …

Positive Feedback Between Tree Establishment And Patterns Of Subalpine Forest Advancement, Glacier National Park, Montana, U.S.A., Matthew F. Bekker

Wasatch Dendroclimatology Research

The development and maintenance of several types of visually striking vegetation patterns are controlled by positive feedback between pattern and process. These patterns are particularly common at ecotones, where the influence of positive feedback may affect the position and dynamics of the boundary between the adjacent biotic communities. In this study, I use dendrochronology to examine the role of feedback between existing trees and the establishment and survival of seedlings in the advancement of linear, finger-like strips of subalpine forest in Glacier National Park, Montana. A general upslope, windward to leeward pattern of older trees followed by progressively younger trees …

Spatial Ecology Of Swift Fox Social Groups: From Group Formation To Mate Loss, Ann M. Kitchen, Erik M. Gese, Seija M. Karki, Edward R. Schauster

United States Department of Agriculture Wildlife Services: Staff Publications

We examined social group formation, movements and denning relative to other group members, home-range use, and the response to social group disruption among 188 radiocollared swift foxes (Vulpes velox) in Colorado. We found that during the initial stages of pair formation mated foxes shared dens more frequently than during the remainder of their pair-bond. The average distance between mated pairs was influenced by season and time of day, with the greatest proximity in the breeding season (727.2 m 6 42.3 SE), and during diurnal hours (463.7 6 34.7 m). Female foxes spent more time in the core area of the …

In-Burrow Application Of Rozol To Manage Black-Tailed Prairie Dogs, Charles D. Lee, Philip Gibson, Jeff Wilson

Wildlife Damage Management Conference Proceedings

Our experiment demonstrated that black-tailed prairie dogs (Cynomys ludovicianus) will consume rodenticide underground in their burrows. We demonstrated the efficacy of Rozol Pocket Gopher Bait containing the active ingredient chlorophacione (0.005%) 21 days post treatment for managing black-tailed prairie dogs in their burrows in Kansas. Active prairie dog burrows were reduced 90% when 54 grams of Rozol was placed in the burrow without prebaiting. Results indicate use of this toxicant when placed in the burrow can be an effective means of managing prairie dogs. In-burrow application of rodenticides for black-tailed prairie dog management should markedly reduce exposure of …

Badger Movement Ecology In Colorado Agricultural Areas After A Fire, Craig Ramey, Jean Bourassa

Wildlife Damage Management Conference Proceedings

While investigating the American badger (Taxidea taxus) in eastern Colorado’s wheatlands, we studied 3 badgers which were affected by a 2.1 km² man-made fire and compared them to 2 adjacent badgers unaffected by the fire. All badgers were equipped with radio-telemetry collars and generally located day and night for approximately 1 month pre-fire and 3 weeks post-fire. Three point triangulation locations were converted into a global information system database. Adaptive kernel analyses compared pre- and post-fire horizontal: home ranges (i.e. 95% utilization areas, UAs), core activity areas (50% UAs), movements, den and habitat use patterns. Mean (x) …

Facts From A Year Of Drought: Forage Competition Between Livestock And The Mongolian Pika (Ochotona Pallasi) And Its Effects On Livestock Densities And Body Condition, Vroni Retzer

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Burrowing small mammals in grasslands have long been regarded as pests because they compete for forage with livestock and reduce the forage availability for livestock by destroying pastures through their intensive digging activity.

In order to investigate forage competition between the Mongolian Pika (Ochotona pallasi) and livestock an exclosure experiment consisting of four different treatments was set up. The treatments were: 1) accessible only for pikas, (only pika) 2) accessible only for livestock, (only livestock) 3) accessible for both herbivore groups (pika & livestock) and 4) no grazing (no grazing). During the investigation period all requirements for forage …

Preface to Erforschung biologischer Ressourcen der Mongolei, band 9, 2005.

First paragraph:

The present volume 9 of ”Biologische Ressourcen der Mongolei” continues the cooperation between the National University of Mongolia, Ulaan Baatar, and German academic institutions, mainly led by the University of Halle-Wittenberg. Thus, the volume stands in a tradition stretching now over 40 years (described in the respective chapter written by Stubbe et al.), but also raises new issues and topics. The chapters provided by Ts. Jamsran, W. Hilbig, E. Jäger, M. Stubbe und A. Stubbe demonstrate nicely that this cooperation is not only based on continued institutional …

Black-Tailed Prairie Dog Colony Dynamics In South Dakota Over A 10-Year Period, Kathleen Fagerstone, Howard Tietjen, James Glahn, Greg Schenbeck, Jean Bourassa

Wildlife Damage Management Conference Proceedings

Between 1968 and 1978, aerial photography was used to monitor distribution of blacktailed prairie dog (Cynomys ludovicianus) colonies on a 400-square mile area in South Dakota, including parts of Buffalo Gap National Grassland, Pine Ridge Indian Reservation, and Badlands National Monument (now Badlands National Park). Aerial photographs were taken of the study area in 1968 and annually from 1974 through 1978 at a scale of 1:20,000 (1968) and 1:15,840 (1974- 1978). Prairie dog colonies were identified on the photographs, outlined, and the outline transferred to USGS topographic maps for colony size measurements. This technique reliably detected changes in …

Quantification And Prediction Of Stream Dryness In The Interior Highlands, Justin M. Homan, Nicholas M. Girondo, Charles J. Gagen

Faculty Publications - Biological Sciences

Although ecological studies have noted streams drying in the Interior Highlands, published measurements of streambed dryness are lacking. Clearly, stream drying has the potential to affect benthic macroinvertebrate and fish communities. In 2003, we initiated an assessment of streambed dryness for three streams in the Ouachita Mountains representative of the Central Hills, Ridges, and Valleys. In the following summer, we applied the approach to 15 similar size watersheds in three distinct ecoregions of the Interior Highlands: Ouachita Mountains-Athens Plateau, Ozark Highlands-Springfield Plateau, and Lower Boston Mountains. Repeated dryness measurements were recorded in each stream and correlated to nearby USGS stream …

Macroinvertebrate Community Of Ecology Of Lowland, Subtropical Streams In Louisiana, Michael Douglas Kaller

LSU Doctoral Dissertations

Freshwater ecosystems, particularly streams and rivers, have been the subject of prodigious research. Unfortunately, in comparison to neighboring regions, the Gulf of Mexico coastal plain has not received as much attention. Therefore, I collected data on the macroinvertebrates of these streams to begin the understanding of the relationships between community structure and environmental characteristics. In contrast to the hypothesized ancestral streams of these macroinvertebrates, coastal plain streams are commonly devoid of rocks leaving only woody debris as usable hard substrates and are typically lower in dissolved oxygen. I examined habitat selection by colonization of woody debris with large and small …

Ecology And Conservation Of Louisiana Black Bears In The Tensas River Basin And Reintroduced Populations, John Farnum Benson

LSU Master's Theses

Louisiana black bears (Ursus americanus luteolus) exist in 3 isolated populations in Louisiana and are listed as a threatened subspecies under the United States endangered species act. In order to establish a population of black bears in central Louisiana and to promote connectivity among existing populations 11 adult females and 28 cubs were reintroduced to suitable habitat on Lake Ophelia National Wildlife Refuge. We captured and monitored females in the Tensas River Basin (TRB) in northeast Louisiana for use in these reintroduction efforts and to study their ecology. Specifically, I studied the food habits, space use, habitat selection, and denning …

Population Dynamics Of A Diverse Rodent Assemblage In Mixed Grass-Shrub Habitat, Southeastern Colorado, 1995–2000, Charles H. Calisher, James N. Mills, William P. Sweeney, J. Jeffrey Root, Serena A. Reeder, Emily S. Jentes, Kent Wagoner, Barry J. Beaty

United States Department of Agriculture Wildlife Services: Staff Publications

We followed seasonal and year-to-year population dynamics for a diverse rodent assemblage in a short-grass prairie ecosystem in southeastern Colorado (USA) for 6 yr. We captured 2,798 individual rodents (range, one to 812 individuals per species) belonging to 19 species. The two most common species, deer mice (Peromyscus maniculatus) and western harvest mice (Reithrodontomys megalotis), generally had population peaks in winter and nadirs in summer; several other murid species demonstrated autumn peaks and spring nadirs; heteromyids were infrequently captured in winter, and populations generally peaked in summer or autumn. Interannual trends indicated an interactive effect between …

Use Of Fecal Glucocorticoid Metabolite Measures In Conservation Biology Research: Considerations For Application And Interpretation, Joshua J. Millspaugh, Brian E. Washburn

United States Department of Agriculture Wildlife Services: Staff Publications

Fecal glucocorticoid metabolite analyses are increasingly being used by a variety of scientists (e.g., conservation biologists, animal scientists) to examine glucocorticoid (i.e., stress hormone) secretion in domestic and wild vertebrates. Adrenocortical activity (i.e., stress response) is of interest to conservation biologists because stress can alter animal behavior, reduce resistance to disease, and affect population performance. The noninvasiveness of fecal-based assessments is attractive, particularly when studying endangered species, because samples can often be obtained without disturbing the animal. Despite such advantages, many confounding factors inhibit the utility of this technique in addressing conservation problems. In particular, interpretation of fecal glucocorticoid metabolite …
