Capture-Recapture Of White-Tailed Deer Using Dna Sampling From Fecal Pellet-Groups, Matthew James Goode

Masters Theses

Reliable density estimates of game and keystone species such as white-tailed deer (Odocoileus virginianus) are desirable to set proper management strategies and for evaluating those strategies over time. However, traditional methods for estimating white-tailed deer density have been inhibited by behavior, densely forested areas that can hamper observation (detection), and invalid techniques of estimating effective trapping area. We wanted to evaluate a noninvasive method of mark-recapture estimation using DNA extracted from fecal pellets as the individual marker and for gender determination, coupled with a spatial detection function to estimate density (Spatially Explicit Capture-Recapture, SECR). We collected pellet groups …

Virginia Shellfish Aquaculture Situation And Outlook Report : Results Of The 2010 Virginia Shellfish Aquaculture Crop Reporting Survey, Thomas J. Murray, Karen Hudson

Reports

Recent growth of the shellfish aquaculture industry in Virginia has added significant value to the state’s seafood marketplace. Today, watermen continue to harvest both hard clams and oysters from the state’s public resources, albeit at diminished rates. At the same time, Virginia’s watermen-farmers are providing growing quantities of additional quality shellfish to consumers. Following the lead of the hard clam industry, there has been a significant transition to intensive aquaculture of native oysters in recent years. The once extensive oyster planting has disappeared primarily as a result of endemic oyster diseases and increasing wildlife predation of seed oysters. In its …

Developing Mechanisms For The Transfer And/Or Adjustment Of Rock Lobster Shares Between Sectors In Western Australia And South Australia., Chris Reid

Fisheries management papers

The purpose of this report has been to investigate potential reallocation mechanisms for the transfer and/or adjustment of catch shares between sectors and the requirements to allow for their implementation, with particular reference to their application in the Western and South Australian rock lobster fisheries. While the report focuses on the commercial and recreational sectors of these fisheries, potentially all non-commercial fishing sectors could be included under a given mechanism in the same manner as that outlined for the recreational sector, subject to the appropriateness of allowing the sector’s allocation to be transferable

Native Grassland Management Guidelines For Nebraska's Wildlife Management Areas, Gerry Steinauer, Kent Pfeiffer, Jarren Kuipers

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

This document is one of a four part series produced by the Nebraska Game and Parks Commission to provide direction to managers of Wildlife Management Areas (WMAs) in Nebraska. Other documents in the series cover management of woodlands, wetlands, and converted habitats.

Prior to EuroAmerican settlement grasslands covered 98% of the Nebraska landscape and supported the majority of the state’s biodiversity. Since settlement, Nebraska’s native grasslands have suffered serious decline. For example, approximately 98% of eastern Nebraska’s tallgrass prairie has been lost to development. In central and western Nebraska grassland losses have been less dramatic though still substantial. Remnant grasslands …

2010 Vegetation Survey Of The Fort Niobrara National Wildlife Refuge (Final Report To The Nebraska Game And Parks Commission, U.S. Fish And Wildlife Service, And The Sandhills Prairie Refuge Association), Robert F. Steinauer

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

Fort Niobrara National Wildlife Refuge (FNNWR) is located on the Niobrara River in north central Cherry County, NE. There is little detailed information available documenting the vegetation of FNNWR. Tolstead (1942) studied the grasslands of northern Cherry County, (including FNNWR) with a focus on describing the dominant species of grassland types and determining the relationships between vegetation distribution and environmental variables and management practices. Churchill et al (1988) described the vascular flora of The Nature Conservancy’s nearby Niobrara Valley Preserve. Fiest et al (2010) conducted vascular plant surveys on portions of the FNNWR in 2009 and compiled a partial vascular …

Using The Judas Technique To Locate And Remove Wintertime Aggregations Of Invasive Common Carp, P. G. Bajer, Christopher J. Chizinski, P. W. Sorensen

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Radio- and acoustic telemetry in three Midwestern lakes demonstrated that common carp, Cyprinus carpio L., aggregate as water temperatures descend below 10C. Particularly dense aggregations formed at temperatures <5 >C, and once located, these aggregations could be removed with an efficiency of up to 94% using seine nets. Carp aggregated just below the surface of the ice (approximately 1.5 m) and rarely descended to warmer waters, which extended down to 10 m. Although aggregations consistently formed close to shore, their locations could not be explained by temperature or dissolved oxygen. The aggregations also moved frequently, making radio-tagged fish invaluable to locate …

Mixed-Source Reintroductions Lead To Outbreeding Depression In Second-Generation Descendents Of A Native North American Fish, David D. Huff, Loren M. Miller, Christopher J. Chizinski, Bruce Vondracek

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Reintroductions are commonly employed to preserve intraspecific biodiversity in fragmented landscapes. However, reintroduced populations are frequently smaller and more geographically isolated than native populations. Mixing genetically, divergent sources are often proposed to attenuate potentially low genetic diversity in reintroduced populations that may result from small effective population sizes. However, a possible negative tradeoff for mixing sources is outbreeding depression in hybrid offspring. We examined the consequences of mixed-source reintroductions on several fitness surrogates at nine slimy sculpin (Cottus cognatus) reintroduction sites in south-east Minnesota. We inferred the relative fitness of each crosstype in the reintroduced populations by comparing …

Breeding Bird Response To Partially Harvested Riparian Management Zones, Christopher J. Chizinski, Anna Peterson, Joann Hanowski, Charles R. Blinn, Bruce Vondracek, Gerald J. Niemi

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

We compared avian communities among three timber harvesting treatments in 45-m wide even-age riparian management zones (RMZs) placed between upland clearcuts and along one side of first- or second-order streams in northern Minnesota, USA. The RMZs had three treatments: (1) unharvested, (2) intermediate residual basal area (RBA) (targeted goal 11.5m²/ha, realized 16.0m2/ha), and (3) low RBA (targeted goal 5.7m²/ha, realized 8.7m²/ha). Surveys were conducted one year pre-harvest and three consecutive years post-harvest. There was no change in species richness, diversity, or total abundance associated with harvest but there were shifts in the types of …

Implications Of Community Concordance For Assessing Stream Integrity At Three Nested Spatial Scales In Minnesota, U.S.A., Christine L. Dolph, David D. Huff, Christopher J. Chizinski, Bruce Vondracek

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

1. Fish and invertebrate assemblage data collected from 670 stream sites in Minnesota (U.S.A.) were used to calculate concordance across three nested spatial scales (statewide, ecoregion and catchment). Predictive taxa richness models, calibrated using the same data, were used to evaluate whether concordant communities exhibited similar trends in human-induced taxa loss across all three scales. Finally, we evaluated the strength of the relationship between selected environmental variables and the composition of both assemblages at all three spatial scales.

2. Significant concordance between fish and invertebrate communities occurred at the statewide scale as well as in six of seven ecoregions and …
