The Unionid Mussels Of The Upper Iowa And Turkey River Watersheds, Jim Eckblad, Brett Ostby, Karis Tenneson Jan 2002

The Unionid Mussels Of The Upper Iowa And Turkey River Watersheds, Jim Eckblad, Brett Ostby, Karis Tenneson

Journal of the Iowa Academy of Science: JIAS

The Iowa driftless region occupies an area of about 9,000 km2 in the northeastern corner of Iowa and is drained by relatively old entrenched meandering streams. The Upper Iowa River and Turkey River are the largest of these streams. During the period from June, 1999 to October, 2000, a total of 193 sites were surveyed for mussels from the Upper Iowa River, the Turkey River, and their main tributaries. Surveys were conducted by hand using a 10 m bank-to-bank search at each site. Data analysis was facilitated using ArcView GIS. The presence of mussels was recorded at 75% of …

Effects Of Cattle Grazing On Woodlands In Central Iowa, Cathy Mabry Jan 2002

Effects Of Cattle Grazing On Woodlands In Central Iowa, Cathy Mabry

Journal of the Iowa Academy of Science: JIAS

Iowa's forests have undergone a dramatic decline in area since settlement by Europeans. Most of the remaining forests have been degraded by an assortment of human impacts, with cattle grazing the most prominent among them. Using a matched pairs study designed to control for environmental differences among plots, I examined the impact of cattle grazing on the forest understory, canopy trees, and tree regeneration. There were distinct groups of understory species associated with ungrazed and grazed plots. Species associated with ungrazed plots were all native and tended to be perennial herbs with fleshy roots. Ungrazed plots also had species preferring …

Analyzing Anthropogenic Landscapes With Gis And Remote Sensing: A Literature Review, Andi O. Kraft Jan 2002

Analyzing Anthropogenic Landscapes With Gis And Remote Sensing: A Literature Review, Andi O. Kraft

Nebraska Anthropologist

Anthropogenic landscapes are those that have been modified, to varying degrees, by human. Their development is affected by the over-use of natural landscapes in the past such as overgrazing, frequent fires, or excessive depletion of forests. Anthropologists analyzing land-use intensification are now realizing the promise of geographical information systems (GIS) and remote sensingfor their research. A literature review of case studies done on varying anthropogenic landscapes will highlight how GIS can give practical integration of geographic spatial structures (habitation, soils, river drainage) to past and current relationships between the environment and human systems when combined with local-level knowledge. Research of …

Strategies For Controlling House Fly Populations Resistant To Cyromazine, Diana C. Crespo, Roberto E. Lecuona, Jerome Hogsette

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The objectives of this study were to compare, from both biological and economic viewpoints, the impact of various control strategies and evaluate their effect on cyromazine-resistant Musca domestica L., and beneficial house fly pupal parasitoids on caged-layer farms (240,000 hens) in Argentina. The strategies evaluated were: chemical, chemical + cultural, and chemical + cultural + biological (integrated management). The products used were: cyromazine 1% and 50%, DDVP, azamethiphos with and without z-9-tricosene, lime, and the parasitoids Spalangia endius Walker and Muscidifurax raptor Girault & Sanders. In the absence of control measures, fly density increased quickly and the average parasitism rate …

The Cultural Ecology Of Pastoralism In Eritrea: A Geographical Inquiry, Woldetensae Tewolde Kahsaye Jan 2002

The Cultural Ecology Of Pastoralism In Eritrea: A Geographical Inquiry, Woldetensae Tewolde Kahsaye

LSU Doctoral Dissertations

This dissertation is an investigative cultural ecologic study of the pastoralists in the eastern and northwestern lowlands of Eritrea. Tigre, Hidareb, and Rashaida herders were identified and studied throughout the fieldwork. These ethnic groups constitute people with defined cultural and economic characteristics inhabiting environments characterized by marked seasonal variations in precipitation. Their livelihoods are almost wholly dependent on livestock forming types of modes of production identified as pure-pastoralism and agro-pastoralism. The distinction between these two forms lies primarily in the type of economic strategy pursued (i.e., wholly livestock-based economy versus livestock-crop economy) as well as in the pattern of pastoral …

[The Akumal (Mexico) Coral Reef Monitoring Program 1994-2001], Liz Dries

Capstone Projects and Master's Theses

The value of coral reefs for developing countries and areas where tourism is on the rise make the management of the reef a high priority. Akumal, Mexico is no exception. For management to be effective, information for accurately evaluating the condition of the reef is critical. This study was done to test the hypothesis that there has been no change in percent coral coverage (PCC) on Las Redes Reef, in Akumal, Mexico between 1996 and 2001. To test this hypothesis I compared data I collected during the summer of 2001 to PCC data collected by interns and students working in …

Assemblages Of Breeding Birds As Indicators Of Grassland Condition, Sharon Freshman Browder, Douglas H. Johnson, I. J. Ball Jan 2002

Assemblages Of Breeding Birds As Indicators Of Grassland Condition, Sharon Freshman Browder, Douglas H. Johnson, I. J. Ball

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

We developed a measure of biological integrity for grasslands (GI) based on the most influential habitat types in the Prairie Pothole Region of North Dakota. GI is based on proportions of habitat types and the relationships of these habitat types to breeding birds. Habitat types were identified by digital aerial photography, verified on the ground, and quantified using GIS. We then developed an index to GI based on the presence or abundance of breeding bird species. Species abundance data were obtained from 3 min roadside point counts at 889 points in 44, 4050 ha study plots over a 2-year period. …

Species Richness, Latitude, And Scale-Sensitivity, S. Kathleen Lyons, Michael R. Willig Jan 2002

Species Richness, Latitude, And Scale-Sensitivity, S. Kathleen Lyons, Michael R. Willig

School of Biological Sciences: Faculty Publications

The latitudinal gradient of species richness is well documented for a variety of taxa in both terrestrial and aquatic environs. Moreover, a number of recent attempts to assess the effects of scale on the relationship have concluded that the latitudinal pattern is scale-invariant. Nonetheless, the power of those approaches is predicated on precise knowledge of the forms of the latitudinal gradient, the area relationship, and their interaction. We used a model developed by J. Pastor, A. Downing, and H. E. Erickson for assessing the effects of scale on the productivity–diversity gradient to avoid such complications. More specifically, for 253 sets …


The Impact Of Buffer Strips And Stream-Side Grazing On Small Mammals In Southwestern Wisconsin, Erik W. Chapman, Christine A. Ribic Jan 2002

The Impact Of Buffer Strips And Stream-Side Grazing On Small Mammals In Southwestern Wisconsin, Erik W. Chapman, Christine A. Ribic

United States Geological Survey: Staff Publications

The practice of continuously grazing cattle along streams has caused extensive degradation of riparian habitats. Buffer strips and managed intensive rotational grazing (MIRG) have been proposed to protect and restore stream ecosystems in Wisconsin. However, the ecological implications of a switch from traditional livestock management to MIRG or buffer strip establishment have not been investigated. Differences in small mammal communities associated with riparian areas on continuously grazed and MIRG pastures, as well as vegetative buffer strips adjacent to row crops, were investigated in southwestern Wisconsin during May–September 1997 and 1998. More species (mean of 6–7) were found on the buffer …


Invasion Of Indigenous Vegetation In South-Western Australia By Leptospermum Laevigatum (Gaertn.) F. Muell. (Myrtaceae), Anya Lam Jan 2002

Invasion Of Indigenous Vegetation In South-Western Australia By Leptospermum Laevigatum (Gaertn.) F. Muell. (Myrtaceae), Anya Lam

Theses : Honours

The current paradigm of biodiversity conservation requires the assessment of alien plant invaders, and their potential negative impacts on indigenous species and communities. Leptospermum laevigatum (Gaertn.) F. Muell. (Victorian tea tree/ Coast tea tree) is indigenous to eastern Australia. It has invaded ecosystems within its natural biogeographic range, within new ranges in Australia and overseas. The species is listed as a high priority weed in the Environmental Weed Strategy for Western Australia. However, the basis for its listing has been casual observation rather than focussed research. This study of L. laevigatum is unique in being the first to …

Ecology And Growth Of Tamias Palmeri And Testing Of A Protocol To Monitor Habitat Relationships, Christopher Eric Lowrey Jan 2002

Ecology And Growth Of Tamias Palmeri And Testing Of A Protocol To Monitor Habitat Relationships, Christopher Eric Lowrey

UNLV Retrospective Theses & Dissertations

The ecology of Tamias palmeri is investigated. Presence-absence and relative abundance of T. palmeri are related to principle component scores of habitat variables using logistic regression and multiple linear regression, respectively. Relative abundance of Tamias palmeri estimated with live capture-recapture was positively correlated with shrub cover and negatively correlated with slope. Timing of emergence from dens by juveniles was earlier and weights of juveniles were greater in ravine areas as compared to upslope areas. Track plates were not correlated with trap captures. Track plate success was not correlated with habitat variables. The results of this study were used to build …

Evaluation Of Persistent Organic Pollutant Levels And Effects In Alaskan Natives, Marie Lenore Socha Jan 2002

Evaluation Of Persistent Organic Pollutant Levels And Effects In Alaskan Natives, Marie Lenore Socha

All ETDs from UAB

Alaskan Native women may be at an increased risk of exposure to persistent organic pollutants (POPs) because they eat a subsistence diet that contains elevated levels of these chemicals. Research suggests that these chemicals may be capable of acting like estrogens, and thus could increase a woman's risk of developing breast cancer. The objectives of this research were to (1) determine overall body burdens of POPs in Alaskan Natives and compare these to results from the Second National Health and Nutrition Examination Survey (NHANES II); (2) determine if geographical location within Alaska correlates with a woman's body burden of POPS; …
