Wolverines exhibited significantly more wear and damage than lynx.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.Additional long-term studies should be conducted on T. major in order to evaluate multi-seasonal behavior to compare with other T. major populations and the seasonal behavior of other T. Indian Stream, located in northern New Hampshire supports healthy populations of trout in its headwaters; yet the summer 2010 temperatures at the confluence of Indian Stream approached 32°C (90°F).

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.

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.

While Eurasian lynx (Lynx lynx) and wolverines (Gulo gulo) have been extensively studied in regard to their physical characteristics, behavior, life cycle, and habitat, there is limited data on the damage and wear of their teeth, which are excellent indicators of health and overall condition of an organism.

The goal of this study was to identify if senescence in conjunction with foraging strategy is associated with dental deterioration and how these factors could affect quality of life.When water temperatures would decrease trout would spread out and take advantage of foraging habitat.Trout that occupied the Connecticut River near the confluence of Indian Stream moved very little.With a lack of natural predation and decreased active hunting by humans, population density of white-tailed deer has increased dramatically in places across the northeast over the last century.High population densities are known to directly lead to decreased seedling and sapling growth of woody and herbaceous plant species that are considered deer’s preferred food, and over time preferential browsing can modify habitat by altering long-term forest regeneration.Dentition was visually assessed to determine degree of wear and what types of damage were sustained.Lynx, which are obligate carnivores, were found to have virtually no wear on average on their canines and premolars whereas the wolverines, being facultative scavengers, also had little wear on their premolars and molars but their canines were worn to a smooth tip on average.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).Habitat use and selection was evaluated using generalized linear models (glms) and chi-square analyses from Florida land cover raster information and five-meter habitat assessments during radiotelemetry locations.Females utilized and had a higher proportion of coniferous habitats within their home ranges compared to males who preferred forested wetlands.
