Development and evaluation of devices designed to minimize deer-vehicle collisions : phase II( )

1 edition published in 2010 in English and held by 2 WorldCat member libraries worldwide

We evaluated behavioral responses of captive white-tailed deer to visual and physical barriers designed to minimize deer-vehicle collisions, determined effects of exclusion fencing on movements of free-ranging deer, and further tested the visual capabilities of deer, as related to potential mitigation strategies. We tested the efficacy of several fencing designs and that of a layer of rip-rap rock for restricting movements of captive deer. Woven-wire fences <1.8 m tall, similar heights of opaque fencing, and rip-rap rock each were ineffective. Both 1.8-m and 2.4-m woven-wire fences were relatively more effective. Woven-wire fences>2.1-m tall and 1.2-m woven-wire fences with a top-mounted outrigger were most effective. We studied movements of free-ranging deer before and after construction of 1.6-km of 2.4-m woven-wire and 1.6-km of 1.2-m woven-wire with a top-mounted outrigger. Fencing did not affect deer home range size, and deer often circumvented fence ends. Daily deer movements in response to fencing were reduced by 98% and 90% for the 2.4-m and outrigger designs, respectively. The outrigger design has potential for reducing collisions because of its relative affordability and ability to function as a 1-way barrier. To further test deer vision, as related to deterrents to roadway crossing, we developed an automated system for training deer to associate a white-light stimulus with a food reward. Each of six captive deer correctly identified the positive reward in>75% of trials by Day 19. We will use this system to further characterize the visual thresholds of deer, and to test innovative roadside mitigation strategies
In situ measurement of riparian groundwater denitrification in a short-rotation pine dominated watershed by Johnson Barker Jeffers( )

1 edition published in 2018 in English and held by 1 WorldCat member library worldwide

Here, we estimate denitrification in shallow groundwater to help determine if current streamside management zones (SMZs) can mitigate nitrate input from short-rotation pine management in the Upper Atlantic Coastal Plain. Water samples were collected monthly for a year and analyzed for nutrient (NO3-, NH4+, TN, DOC) and dissolved gas (N2, Ar, N2O) concentrations from the Fourmile Watershed at the Savannah River Site. Excess-N2 produced by denitrification was measured using MIMS and N2:Ar ratios. Nitrate concentrations decreased between the edge of the SMZ and the intermittent stream valley. N2O was the dominant end product in the pine plantation. Median denitrification reaction progress ranged from 0.47 to 0.94. Environmental conditions, such as low pH, fluctuating water table, high concentrations of NO3-, and low levels of DOC, inhibited complete denitrification in the shallow groundwater. Denitrification in the SMZ mitigates the additional nitrogen inputs from short-rotation woody crop (SRWC) management
Valuing different loblolly pine plantation regimes considering traditional and non-traditional timber products and price uncertainties. by Umesh Kumar Chaudhari( )

1 edition published in 2017 in English and held by 1 WorldCat member library worldwide

Loblolly pine (Pinus taeda) is widely planted in the southern US due to its adaptability, growth rate and suitability for timber markets. It is the premier species in a region that contributes a significant portion of industrial roundwood to the U.S. and the world. This research used three installations (sites) of the Plantation Management Research Cooperative (PMRC) Culture Density Study from the Lower Coastal Plain of Georgia and Florida as case studies to examine loblolly pine timber yields and financial returns from traditional and integrated (including bioenergy feedstock) forest product mixes and a feedstock only scenario for combinations of site class, cultural regime, and density management (planting density and thinning). Financial returns were determined using the Black and Scholes model under the real options analysis approach (ROA) and the traditional discounted cash flow approach of net present value (NPV). Management regimes were ranked using the equivalent annual annuity (EAA) approach for both ROA and NPV due to varying optimum rotation age as influenced by site class, planting density, cultural regime, and thinning scenario. Conclusions regarding best management regimes were the same using ROA and NPV; however, ROA returns were higher as it captured the value from product price volatilities which NPV did not. Financial returns for integrated forest products were greater than for traditional timber product due to the addition of bioenergy feedstock revenues. For the traditional product mix, the optimum regime for low and average site classes was 600 TPA planting density with intensive culture and two thinnings while that for the high site was 900 TPA, operational culture, and two thinnings. Optimum regimes for the integrated forest product mix were similar with the exception that the 600 and 900 TPA densities provided similar returns for each site class. Financial returns for the integrated products mix regimes were generally much less than for bioenergy feedstock dedicated regimes but the feedstock dedicated regime returns reflected unusually high historical prices
The effects of meso-mam67iujjm mal removal on northern bobwhite populations by Alexander Lee Jackson( )

1 edition published in 2017 in English and held by 1 WorldCat member library worldwide

Perceived changes in predator-prey dynamics along with documented declines of Northern Bobwhite (Colinus virginianus) have created a renewed interest about the role meso-mammals play in shaping bobwhite population trajectories. Therefore, I evaluated the efficacy of meso-mammal trap and removal (MMTR) at reducing meso-mammal activity and increasing bobwhite reproductive success. I evaluated bobwhite reproduction from data collected during 1999-2006 on 11 sites in 3 states across the southeastern United States. I evaluated the relationships between MMTR, predator activity, and bobwhite reproduction using 37 site-year combinations when MMTR occurred and 20 combinations when it did not occur. I then constructed a population model to evaluate the effects of MMTR on bobwhite population performance under different assumptions about density dependence, bobwhite vital rates, and harvest strategies. My results suggest that MMTR reduces meso-mammal activity, positively affects bobwhite reproduction, and increases bobwhite population performance
Seeing spots in the swamp: Using camera data to estimate white-tailed deer fawn survival and recruitment in South Florida by Kristin Nicole Engebretsen( )

1 edition published in 2018 in English and held by 1 WorldCat member library worldwide

In South Florida, white-tailed deer (Odocoileus virginianus) are an important game species and primary prey of the endangered Florida panther (Puma concolor coryi). Due to a potential decline in South Florida deer populations, updated information is needed about fawn survival and recruitment. During the 2016 fawning season, I deployed 180 passive cameras in South Florida, identified 123 individual fawns, and used a novel spatial capture-recapture model to estimate number of fawns born and recruited. An estimated 211 (95% CI 180-250) fawns were born in the 10,941-ha study area, and the density of birth locations was greatest in cypress forests and in areas with more frequent fire. Only 37 (95% CI 27-48) of 211 fawns survived to 180 days, indicating 18% of fawns reached sexual maturity. However, 2016 was an extraordinarily wet year and multi-year studies are needed to determine if recruitment is high enough to offset mortality in this population
Using nutrients and microbiota bioassessment to investigate potential benefits of gricultural wetlands by Cody Thomas Matteson( )

1 edition published in 2018 in English and held by 1 WorldCat member library worldwide

Here we evaluate field-to-stream water quality gradients across a forested alluvial swamp and through a ditched wetland swale on the same working farm. During 2016 and 2017, soil, surface water, and shallow groundwater samples were collected on this farm and analyzed for nitrate + nitrate (nitrate), total phosphorus (TP), and microbial species richness and biovolume. Significant nitrate and TP reduction occurred as shallow groundwater and surface water moved from the farm through an alluvial swamp. Conversely, a ditched depressional wetland swale with cropping on the margins did not significantly alter nutrient concentrations between where water enters the wetland and its discharge point. While pollutant additions were similar into both types of floodplain wetlands, water quality improvements were distinct in the alluvial swamp. Cyanobacteria algal abundance and biovolume correlated positively with phosphorus levels in both nutrient rich agricultural wetlands, and negatively with light intensity
Factors affecting altitudinal migration of long-tailed manakins (Chiroxiphia linearis) in a tropical agricultural landscape by An Chee Hsiung( )

1 edition published in 2016 in English and held by 1 WorldCat member library worldwide

Altitudinal migration exists in many taxa around the world, yet our understanding of the factors influencing the behavior is limited. The objectives of this study were to gain a deeper understanding of altitudinal migration by synthesizing existing knowledge and by studying migratory propensity of a tropical bird species. First, I conducted a literature review highlighting common patterns and drivers of altitudinal migration, current knowledge gaps, and conservation implications of the behavior. I then investigated altitudinal migration of long-tailed manakins (Chiroxiphia linearis) in an agricultural landscape in Costa Rica. Capture-recapture and radio telemetry data were collected at low and high elevations between January and April of 2016. Five of the 12 tracked manakins migrated upslope during the study. Manakin abundance decreased in small forest fragments at low elevation and increased at high elevation, while abundance increased at both low and high elevations in large fragments. However, my results did not demonstrate that individual traits such as age, sex, and body size affect migratory propensity
Behavioral and spatial ecology of white-tailed deer in the big cypress basin of florida by Daniel Albert Crawford( )

1 edition published in 2017 in English and held by 1 WorldCat member library worldwide

White-tailed deer (Odocoileus virginianus) in the Big Cypress Basin of Florida encounter a unique set of abiotic and biotic factors, including seasonal flooding and risk of predation, that affect resource selection and space use. Reported declines in local deer populations in recent years warrants renewed focus on the effects of hydrology and predation on deer populations, particularly in light of increased Florida panther (Puma concolor coryi) abundance. To assess the effects of predation risk and seasonal fluctuations in hydrology on the behavioral and spatial ecology of deer, I analyzed camera trap and GPS-telemetry data in the context of the white-tailed deer reproductive cycle and conclude that hydrology and risk of predation by panthers profoundly influence deer behavior and space use as deer attempt to forage optimally under the constraints of predation risk and unpredictable temporal variability in resource availability
A landscape-scale perspective to grassland bird conservation in agroecosystems by John Mark Yeiser( )

1 edition published in 2018 in English and held by 1 WorldCat member library worldwide

Conserving biodiversity in agricultural ecosystems is a global imperative. The Conservation Reserve Program (CRP) is the primary tool for conserving agroecosystems in the United States. There have been positive local effects of programs like CRP, but there is uncertainty about whether local effects scale up to populationlevel benes. We used a landscape-scale approach to understand the effects of a grassland conservation program, the Conservation Reserve Enhancement Program (CREP), on Northern Bobwhite (Colinus virginianus) and other grassland bird populations. We demonstrated that Northern Bobwhite populations were positively influenced by the CREP. However, there can be opportunity costs for other species when landscapes are managed for Northern Bobwhite through these programs. Similarities between landscape-scale resource requirements likely dictate opportunity costs. We provide a decision support tool with which practitioners can establish an adaptive management strategy for private lands
The wild world of guinea worms : transmission dynamics and phylogenetics of the African and north american guinea worms by Christopher Aaron Cleveland( )

1 edition published in 2018 in English and held by 1 WorldCat member library worldwide

Dracunculus medinensis, or Guinea worm (GW), causes a painful and debilitating infection in people. The Guinea Worm Eradication Program (GWEP) has successfully reduced human GW cases from 3.5 million in 21 countries in 1986 to 11 in four remaining endemic countries in 2018. In 2011, an unprecedented increase of GW infections in domestic dogs was reported and incidence has increased annually to 942 in 2018. Epidemiologically, it was posited that transmission may not occur via the classical route (i.e., ingestion of water containing infected copepods), but instead, via a paratenic host. My goals included 1) review Dracunculus species in wildlife and use these data to inform experimental transmission trials, 2) explore novel transmission routes under laboratory conditions, 3) conduct field-based surveillance of potential paratenic hosts in Chad, and 4) investigate the ecology of the North American Guinea worm, D. insignis, in wildlife and domestic animals in the United States. I showed that D. medinensis and D. insignis can experimentally infect several amphibian species, amphibians serve as paratenic hosts and natural D. medinensis infections were found in three frog species in Chad. Although fish did not become infected (as paratenic hosts), fish were able to serve as transport hosts. These data illustrate novel transmission routes with the latter causing great concern as fish are a heavily relied upon in Chad as a food source. Also, villagers feed their cats and dogs fish entrails; our data suggest this could lead to infection. Our U.S.-based studies documented numerous dog and cat infections and that raccoons (Procyon lotor) and opossums (Didelphus virginiana) were common wildlife hosts. The high prevalence of infection in opossums was previously unreported. Based on partial cytochrome c oxidase gene sequences, little diversity was noted among worms from dogs and wildlife and no geographic or host-associations were noted. We also detected D. insignis larvae in musculature of frogs, further confirming that paratenic hosts may be playing a role in transmission of Dracunculus. Collectively, these data have filled several knowledge gaps in the Dracunculus life-cycle, resulting in the development of new interventions to assist the GWEP in endemic countries
