This book was released on 2004 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The impact of agricultural practices on wood turtle (Glyptemys insculpta) movements and survivorship was investigated in a fragmented agri-forest landscape over two years. Agricultural activities and machinery contributed to the death of 20% of radio-tracked turtles. Annual survivorship of adults was 0.904 and 0.868 and for juveniles it was 0.815 and 0.831 for 1998 and 1999, respectively. Mutilation rates in adults were 90% +/- 3% in both years; in contrast, the maximum rate in juveniles was 57%. Setting the cutting height of disc mowers to 100 mm would increase harvest yields, reduce wear on machinery, decrease soil erosion, and reduce turtle mortality and mutilation rates. The concepts of integral, statistical, and linear range are introduced as distinct estimators of turtle movements. Since integral ranges include all habitats critical to survival, they provide an important contribution to our knowledge of imperiled species. Statistical ranges are stable and easily promote within and between study comparisons. Linear ranges quantify migratory and ranging movements. Thread-trailing techniques were used to record the fine-scale movements of six adult male G. insculpta translocated to an experimental hayfield patch-matrix. Although patch size had no effect on move length or path sinuosity, habitat structure did. Paths were generally straighter and move length longer in the harvested portion of a hayfield. Apparent habitat boundaries were shown to be permeable. Subjects exhibit three movement phases: agitation dispersal, local search, and ranging. Thus, G. insculpta exhibit predetermined movement patterns and move to maximize the likelihood of locating resources, while minimizing the probability of revisiting previously searched areas. Recent changes in agricultural practices and machinery are having a decidedly negative impact on G. insculpta. This study provides new insights into the movements of G. insculpta. Such knowledge will be an es" --

Book excerpt: Turtles are a diverse and globally distributed group of vertebrates facing a variety of conservation threats from habitat loss and fragmentation, anthropogenic disturbance, and illegal collection. The eastern portion of North America supports high turtle biodiversity relative to other continents, and many of the endemic species found there are in decline. New and innovative approaches are needed to effectively conserve these animals because many existing practices are failing to slow declines. My graduate work explores two species of threatened turtles, the wood turtle (Glyptemys insculpta) and the eastern box turtle (Terrapene carolina carolina), with a focus on new conservation practices for stream dwelling wood turtles and shell pigment and climate interactions for terrestrial eastern box turtles. In Chapter One I discuss how aquatic turtles have historically been overlooked in stream restoration design with the primary objectives of these projects being the creation of fish habitat and the improvement of water quality. The semi-aquatic wood turtle occurs in riparian systems of northeastern North America where stream restoration is likely to occur, and yet has not been a focal target of restoration design despite its considerable conservation needs. I used a multi-faceted approach to determine why this conservation gap exists, and to assess the potential for developing new relationships between wildlife managers and the stream restoration community in order to deliver benefits to the wood turtle. My assessment consisted of a comprehensive stream restoration literature review, a web-based knowledge and attitude survey of stream restoration practitioners active in Pennsylvania, and a mapping analysis of wood turtle occurrences and stream restoration projects. I found that aquatic turtles in general are not considered in stream restoration design or used as a metric of success in project evaluation. Stream restoration practitioners have a degree of standing knowledge about the species and its habitat, but cite a lack of guidance as a primary reason that they have not taken targeted action for the species. However, survey participants expressed high willingness to consider the species in their work if it can be easily integrated into their existing protocols. My mapping analysis demonstrated a significant overlap of restoration project effort with wood turtle occurrences, and at least $119,000,000 in restoration funding has been expended in watersheds where the species occur. I conclude that, given support for the species among the restoration community and significant overlap of restoration work and the wood turtle, collaborative and interdisciplinary work to include wood turtles in future restoration projects offers the potential to deliver additional conservation benefits through focused designs and risk-reduction measures. In Chapter Two I detail how pigmentation influences many aspects of an organism's ecology, including thermoregulation, and that this relationship is poorly understood in turtles. The thermal melanism hypothesis posits that the dorsal surface of ectotherms will be darker with increasing latitude. This trend has been observed in a variety of herpetofauna, but has not been well studied in turtles despite potential links to climate change and the conservation of turtle populations. The eastern box turtle is a wide-ranging terrestrial species in the eastern United States that is recognizable for its black and yellow pigmentation and patterning. I used the box turtle as a model to test predictions about pigmentation and latitude because it occurs across a variety of terrestrial habitats and latitudes, presenting a unique opportunity to explore pigment variation in detail. I predicted that eastern box turtles at higher latitudes would have a higher proportion of dark pigmented surface on both their carapace and plastron to facilitate solar absorption and heat retention. To test this, I collected dorsal and ventral photos from historical museum specimens and from contemporary individuals. I measured the proportion of light pigmented surface area on the dorsal and ventral surfaces of turtle shells. Across my sample of 417 individuals (190 males, 227 females), there were no differences in pigmentation proportion between the sexes. However, both carapace and plastron surfaces tended to have significantly more light pigmented area as latitude increased, counter to my hypothesis. I explore potential reasons why this terrestrial ectotherm exhibits pigmentation counter to expectations, and how ectotherms in general may be impacted by climate stochasticity. Ectotherms with life-history traits dependent upon ambient temperatures may be at increased risk relative to other taxonomic groups.

This book was released on 2020 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: I investigated the habitat selection of wood turtles (Glyptemys insculpta) in a landscape within active agriculture and assessed the risk of agricultural practices. I tracked 23 wood turtles and recorded their habitat use versus availability on a 3rd and 4th order scale. I found that wood turtles preferred fields over the forest and that hay fields are likely an attractant to wood turtles due to high food availability and low canopy cover. Wood turtles used the hayfields during the hay harvest season, and stayed close to field edges. I monitored the movement response of wood turtles as they were approached by agricultural machinery and found that most turtles could not successfully escape the mower. My study shows that agriculture poses a high risk to wood turtles in an agricultural landscape and management strategies are necessary to prevent populations from extirpation.
