The Spatial Ecology And Microhabitat Selection Of The Pygmy Rattlesnake (Sistrurus Miliarius) In Southwestern Missouri, Dylan Wallace Maag
The Spatial Ecology And Microhabitat Selection Of The Pygmy Rattlesnake (Sistrurus Miliarius) In Southwestern Missouri, Dylan Wallace Maag
MSU Graduate Theses
Despite a wide distribution throughout the southeastern United States, pygmy rattlesnakes (Sistrurus miliarius) have received less research attention than many other rattlesnake species. I captured a total of 33 S. miliarius at the Drury-Mincy Conservation Area (DMCA) and retained 14 large individuals (mostly gravid females) for a radio telemetry study. Snakes were primarily captured during evening road driving surveys and were encountered rarely with any other sampling technique. Sistrurus miliarius are widespread at DMCA where they were encountered in forest, savanna, and glade habitats. Snakes selected microhabitats with more vegetative cover and tree canopy closure than random sites …
Evaluating The Ecological Status Of The Introduced Nile Monitor (Varanus Niloticus) In Florida: Forecasting Presence And Population Expansion Using Computational Geographic Information Systems, Noah G. Cohen
HCNSO Student Theses and Dissertations
The Nile monitor (Varanus niloticus) is a large, carnivorous lizard that has become a notorious invasive species in Florida, USA. Initially released in the 1980s from the pet trade, the species has since established at least three breeding populations and spread throughout much of southern Florida. While current control efforts have failed to eradicate V. niloticus, it is important to attain a better understanding of its invasive dynamics to guide and inform better control strategies. In this study, available georeferenced records of V. niloticus in Florida were compiled and linked to a habitat classification map to evaluate ecotype preferences. Factored …
Examining Movement And Habitat Selection Of Everglades Fishes In Response To Seasonal Water Levels, Gregory J. Hill
Examining Movement And Habitat Selection Of Everglades Fishes In Response To Seasonal Water Levels, Gregory J. Hill
FIU Electronic Theses and Dissertations
Fish distribution patterns and seasonal habitat use play a key role in the food web dynamics of aquatic ecosystems, including the Florida Everglades. In this study I examined the fine scale habitat shifts and movements of spotted sunfish, Lepomis punctatus across varying seasons and hydrologic conditions using in-situ field enclosures and Passive Integrated Transponder (PIT) systems. Data on fish use of three dominant Everglades marsh habitats and activity level were recorded continuously from January to August, 2015. Fish were more active and had the highest use of higher elevation habitats when water levels rose during an experimental reversal in mid-April. …
New Data On Hahnia C.L. Koch, 1841 From Crimea (Aranei: Hahniidae), Mykola Kovblyuk, Zoya Kastrygina, Yuri Marusik
New Data On Hahnia C.L. Koch, 1841 From Crimea (Aranei: Hahniidae), Mykola Kovblyuk, Zoya Kastrygina, Yuri Marusik
Turkish Journal of Zoology
Four species of Hahnia are recorded from Crimea: H. helveola Simon, 1875; H. nava (Blackwall, 1841); H. ononidum Simon, 1875; and H. pusilla C.L. Koch, 1841. Two species, namely H. ononidum and H. pusilla, are recorded from Crimea for the first time. Crimea is the easternmost point of the known range for H. helveola. Illustrations, diagnoses, distribution data, habitats, and seasonal dynamics of activity are presented.
Effects Of A Large-Scale Habitat Enhancement Project On Largemouth Bass Behavior, Feeding, And Growth In Grand Lake, Texas, Chance Kirkeeng
Effects Of A Large-Scale Habitat Enhancement Project On Largemouth Bass Behavior, Feeding, And Growth In Grand Lake, Texas, Chance Kirkeeng
Electronic Theses and Dissertations
The quality of habitat, or the environment suitable for an organism to survive and reproduce, is often described by the type of features present and the quantity and condition of such features. Habitats in many ecosystems are declining and the loss of important habitats likely affects the success of organisms reliant upon those features. Habitats in reservoir ecosystems are especially at risk because of aging processes that are degrading reservoir habitats at faster rates than habitats in other ecosystems. Habitat enhancement projects are one tool used to combat the effects of aging reservoirs but the benefits of these management actions …
Habitat Useage Of Tri-Colored Bats (Perimyotis Subflavus) In Western Kentucky And Tennessee Post-White Nose Syndrome, Katherine Schaefer
Habitat Useage Of Tri-Colored Bats (Perimyotis Subflavus) In Western Kentucky And Tennessee Post-White Nose Syndrome, Katherine Schaefer
Murray State Theses and Dissertations
The tri-colored bat (Perimyotis subflavus) has declined severely across its range since 2006 due to white nose syndrome, a fungal disease causing massive bat mortality in North America. My objective was to determine distinguishing characteristics of roost trees and habitat used by tri-colored bats so that the species’ needs can be considered in management plans. I mist-netted for tri-colored bats in western Kentucky and Tennessee during the summers of 2015 and 2016, and attached a radio transmitter to each captured adult bat. I tracked 15 bats to their day roosts and collected habitat data at 38 roost areas …
A Descriptive Analysis Of Regal Fritillary (Speyeria Idalia) Habitat Utilizing Biological Monitoring Data Along The Big Bend Of The Platte River, Ne, Andrew J. Caven, Kelsey C. King, Joshua D. Wiese, Emma M. Brinley Buckley
A Descriptive Analysis Of Regal Fritillary (Speyeria Idalia) Habitat Utilizing Biological Monitoring Data Along The Big Bend Of The Platte River, Ne, Andrew J. Caven, Kelsey C. King, Joshua D. Wiese, Emma M. Brinley Buckley
Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications
Speyeria idalia populations have declined as much as 95 percent over the last three decades. Here we critically evaluate prairie habitat components along the Platte River in central Nebraska that S. idalia populations require in an effort to better inform conservation efforts. We utilized S. idalia count data from biological monitoring transects where vegetation, soils, land management, and flooding frequency data were also collected to describe the habitat constituents associated with S. idalia presence. We utilize comparative statistics, Pearson’s correlation analysis, and random forest analysis to model S. idalia habitat on land owned and managed by a small conservation NGO. …

Modeling Sex-Specific Seasonal Habitat Selection For Elk (Cervus Elaphus) In Central Washington, Lewis Meyers
Modeling Sex-Specific Seasonal Habitat Selection For Elk (Cervus Elaphus) In Central Washington, Lewis Meyers
All Master's Theses
Elk (Cervus elaphus) are generalist herbivores, exploiting a variety of environments. I studied habitat selection and sexual segregation of the Colockum elk herd in central Washington. I used a resource selection probability function (RSPF) to evaluate habitat use by males and females during summer and winter seasons. I assisted Washington State Department of Fish and Wildlife (WDFW) in capturing and placing GPS collars on males, and used an existing GPS dataset from females to investigate the extent to which sexual segregation was occurring in the Colockum herd. During summer, males selected steep slopes on north, west and south …
