Radiotelemetry and Behavioral Ecology of Neonate Southern Pacific Rattlesnakes
<p>By externally glueing radiotransmitters to the dorsoposterior surface of seven neonate Southern Pacific Rattlesnakes, <em>Crotalus oreganus helleri,</em> I monitored the behavior and ecology of this understudied age-class and species. As an alternative to surgical implantation, external …

Ecology of the Eastern Cottonmouth (<i>Agkistrodon p. piscivorus</i>) at Back Bay National Wildlife Refuge: A Comparative Study of Natural and Anthropogenic Marsh Habitats
<p>Mark-recapture sampling and radiotelemetry were used to investigate populations of the eastern cottonmouth, <em>Agkistrodon p. piscivorus</em>, in both natural and anthropogenic marsh habitats at Back Bay National Wildlife Refuge (BBNWR), Virginia Beach, Virginia from autumn 1995 to late spring …

Movement and Life History Aspects of the Pygmy Rattlesnake in Southwest Missouri
… (Sistrurus miliarius) (N=7) were monitored with radiotelemetry in Christian and Taney Counties of southwest Missouri. Snakes were tracked for periods of 11-73 days and a total of 264 tracking days. Males exhibited significantly greater (P ﹥ 0.05) movement than females and non-gravid individuals …

Circadian Timekeeping of Body Temperature by the Mammalian Suprachiasmatic Nucleus
… a stepwise loss-of-function genetic approach and radiotelemetry recordings. We show that genetic deletion of Bmal1, a non-redundant clock gene for driving the cell-autonomous circadian clock, broadly in the forebrain inclusive of the SCN sufficiently abolished the circadian rhythmicity of Tb. In …

Maternal Effects and Offspring Behavior: Potential Contributors to the Lack of Recruitment in Mississippi Gopher Tortoises (<i>Gopherus polyphemus</i>)
… behavior before being released and monitored via radiotelemetry to monitor dispersal and survival. I found no differences in adult stress or egg yolk CORT between populations. This suggests adults are not excessively stressed. Survival of hatchlings did not differ between sites. Captive-reared …

Population Characteristics and Habitat Selection of Channel Catfish (Ictalurus punctatus) in the Lower James River, South Dakota
… James River. Adult channel catfish monitored by radiotelemetry used complex structural cover types (large snags and rock darns} significantly more (Chi-square=48.83, df=4, P=0.0001) than their availability. Channel catfish used depths between 1.1 and 2.0 m significantly more (Chi-square=58.95, …

Roost-Site Selection of Bats in Northeast Missouri With Emphasis on the Endangered Indiana Bat (Myotis Sodalis)
… may dictate their survival and fitness. I used radiotelemetry to study the roosting ecology of the endangered Indiana bat, Myotis sodalis, at Deer Ridge Conservation Area (DRCA) in northeast Missouri from May through August 2001-2002. Due to the similarities in roost-site characteristics of …

Reproduction and Movement Patterns of the Common Snapping Turtle (Chelydra Serpentina) Inhabiting a Hypothermic Reservoir in Southwest Missouri
… Three turtles from each site were located by radiotelemetry during the summer of 1997. Mean home range size and home range index were not significantly different between sites (P > 0.05). Radio-tagged individuals from Bull Creek maintained significantly greater distances between turtles (DBT) …

Examining environmental and life history correlates of winter and migratory movements in a nomadic Arctic-breeding passerine
… tracked birds using automated digitally-coded radiotelemetry (Motus Wildlife Tracking System) tags deployed on wintering birds in Southwestern Ontario. Additionally, while some individuals were banded, tagged, and released where they were caught, others were strategically displaced by several …

Survival, Movement, and Fine-Scale Habitat Selection of Reintroduced Texas Horned Lizards (Phrynosoma cornutum)
… and woody vegetation in close proximity.” I used radiotelemetry to examine the survival, movement, and fine-scale habitat selection of 23 individual horned lizards released at a reintroduction site in central Texas. The results of my study indicate an early drop in survival within the first few …

Northern pintail nest site selection, nest success, renesting ecology and survival in the intensively farmed prairies of southern Saskatchewan: an evaluation of the ecological trap hypothesis
… in southern Saskatchewan. I also used radiotelemetry to estimate renesting and breeding season survival rates of female pintails; two parameters that are important in productivity and life cycle models. Most (51%) pintail nests were found in crop stubble and generally pintails nested in …

Snakes as predators of bird nests: now and in a warming world
… tracked 33 ratsnakes and 16 black racers using radiotelemetry. An examination of snake habitat use and avian nest survival revealed that racers and coachwhips were frequent predators of nests located near powerlines, due to their use of the shrubland habitat maintained below powerlines. Because …

Conservation and management of the Allegheny woodrat in the central Appalachians
… and among Allegheny woodrat populations.;I used radiotelemetry to examine home range, movements, and habitat use, at colony sites representing two timber harvesting methods, clearcutting and diameter-limit harvesting, and unharvested controls. Home range and foraging distance estimates were …

Winter habitat use by mule deer in Idaho and Montana
… habitat use in different winter ranges. We used radiotelemetry to locate adult female mule deer and estimated microsite habitat conditions including wind speed, snow depth, percent cover of individual plant species, hiding cover, and canopy cover during winter 2010—2011. We compared data at deer …

We used radiotelemetry to locate adult female mule deer and estimated microsite habitat conditions including wind speed, snow depth, percent cover of individual plant species, hiding cover, and canopy cover during winter 2010—2011. We compared data at deer …

Maternal High-Salt Diet During Pregnancy in Sprague Dawley Rats Programs Exaggerated Stress-Induced Blood Pressure and Heart Rate Responses in Adult Female Offspring
… pregnancy. Adult offspring were fitted with radiotelemetry probes to continuously measure blood pressure and heart rate. Rats were placed in restraining cages to test for a programmed acute stress hyperresponsiveness. Offspring were challenged with HS diet for one week to determine if blood …

Ruffed grouse (Bonasa umbellus) habitat ecology in the central and southern Appalachians
… composition. Also presented here were studies of radiotelemetry error, roost site selection, and suitability of prescribed burning as a habitat improvement technique. In the closing chapter I make recommendations for managing Appalachian forests for grouse, which focus on improving winter foraging …

Habitat Niche Modeling in the Texas Horned Lizard (Phrynosoma cornutum): Applications to Planned Translocation
… and resident lizards were monitored via radiotelemetry and using fluorescent powder trails. Telemetry locations and powder trails were overlaid onto habitat suitability models to provide the datasets used to quantify interaction between site occupancy and habitat model predictions. Lizard …

Evaluation of Methodology Use to Estimate Population Size, Sex and Age Ratios, and Mortality of White-tailed and Mule Deer in the Missouri River Breaks Region of South Dakota
… associated with winter aerial deer surveys. Radiotelemetry was used to determine if radio-collared deer were observed during aerial surveys. One hundred three radio-collared deer were observed during aerial surveys from 1998-2000. Stepwise logistic regression indicated that sightability was …
