Weinstein, 2017Abstract: The white-tailed deer (Odocoileus virginianus) is a “problem species” throughout much of urban and suburban United States as a result of its over-abundant numbers stemming from a combination of increasing suburbanization, a simultaneous decrease in agricultural land use, and a lack of apex predators; this combination has resulted in significant increases in acreage returning to forest cover, which in turn, has led to large areas of predator-free habitat for deer.
With high deer numbers comes increased frequency of deer-vehicle collisions (DVCs), unwelcome browsing of residential gardens and ornamental plants, risk of tick-borne illnesses (e.g., Lyme disease), and spread of invasive plant species (some unpalatable to deer) through the consumption of native species by deer.
These increased movement rates in Indian Stream were during periods of increased average temperatures.
Trout tended to congregate during periods of thermal stress and occupy smaller, cooler tributaries and pools where there were cold water inputs.
With regard to other mammal species, there were 28 instances of behavioral reactions from the total 68 video clips recorded of additional mammals in the Experiment sites.
Future studies pertaining to the relationship of senescence and dental health could substantiate findings provided they are able to obtain data from not only a large quantity of specimens from a species, but also equal amounts of each sex and variety of ages particularly from early maturity to geriatric status. Meck, 2018Abstract: An intensive radiotelemetry study was conducted on 21 Terrapene carolina major (Gulf Coast Box Turtle) in the Panhandle of Florida during the summers of 20.I worked with the Norwegian Institute for Nature Research in Trondheim, Norway to assess skulls from their laboratory as well as storage unit within the NTNU University Museum for this study.Individuals identifiable by maturity and sex were used resulting in a total of 61 lynx and 44 wolverines studied.Results showed that trout in Indian Stream had higher movement rates compared to the Connecticut River during the summer months of 2011.Trout that occupied Indian stream during the 2011 field season moved on average 71.4 meters per day, which was significantly higher than trout movement in the Connecticut River during the same time period which averaged 25.1 meters per day.The overall objectives of the study were to assess home range structure, movement behavior, and road mortality risks.Home range analyses using minimum convex polygons and kernel density estimators determined that females had significantly larger home ranges than males both years.The total number of additional mammal species at each camera was also measured, as well as their activity in both treatments.In all, deer were found to behave differently (i.e., exhibit other behaviors besides foraging and basic locomotion) in sites with coyote models, but there were only 17 instances out of the 33 video clips recorded in the Experiment sites in which they reacted fearfully towards the models as expressed by behavioral cues (i.e., tail-flagging with a bounding gait, “alarm snorts”, head-bobbing, and foot-stomping).Trout movement and water temperatures in Indian Stream and the Upper Connecticut River were monitored during 20 field seasons.The objectives of my research were to: 1) Quantify trout movement in the Connecticut River near the confluence of Indian Stream, 2) Determine if there is a correlation between trout movement patterns with season, water temperature, and compare these values between rivers, 3) Identify thermal refugia in Indian Stream, and 4) Recommend management actions for Indian Stream and the Upper Connecticut River below Murphy Dam.
