This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Mining practices can negatively impact turtles through degradation of wetlands and surrounding upland habitat, alteration of movement corridors, accidental mortality, and increased risk of nest and turtle predation. These impacts, in turn, can cause changes in patterns of energy allocation, skewed sex ratios and changed demography, which may ultimately lead to population declines. The aim of my study was to describe the demography of, and identify critical habitat for, a population of globally-endangered Blanding's turtles (Emydoidea blandingii) inhabiting an area of interest for development of a trap rock quarry. In addition to generating important knowledge about population ecology and habitat use, my study can serve as the "before" study in a BeforeAfter Control-Impact (BACI) study quantifying impacts of quarrying on turtles. Using radiotelemetry, GPS dataloggers, and capture-mark-recapture surveys, data were collected at an impact (quarry) site and a control site, and thermal data were collected during overwintering using iButtons. I captured 56 turtles at the impact site and 13 at the control site, and estimated population sizes were 79.6 +/- 17.9 (1.84 turtles/ha) and 16.0 +/- 21.2 (0.32 turtles/ha), respectively. Body size was larger at the control site, but body condition was similar at both sites. Daily distances moved and home range sizes did not differ between sites, and were generally smaller than conspecific values reported in the literature. I identified nesting (15 impact, 2 control) and overwintering (12 impact, 7 control) sites, both considered critical habitats. Overwintering water depth ranged from 30-150 cm (before ice-on) and turtles overwintered at temperatures reported previously in the literature (1.5 to 0.5 oC). My data can be used to quantitatively inform quarry development and mitigation strategies, essential components to balancing the needs of species at risk and humans.

This book was released on 2011 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Blanding's Turtle (Emydoidea blandingii) has received threatened status in the State of Ohio in 2010. The goal of this study is to provide information that can be used in conservation management to locate suitable habitat for conservation of the species as well as potential repatriation or trans location sites. Wetland Inventory and Land Use/Land Cover maps were combined with aerial photography to evaluate regions located in Ohio's Lake Erie Drainage Basin that would meet the essential requirements of the turtles life history by quantitative methods used in Geographic Information Systems (GIS) and Remote Sensing programs. This study identified suitable wetlands and vernal pools, lakes and ponds, and other areas with minimum canopy for nesting and movement. Throughout the region, the highest concentration of available habitat is found in Erie, Lucas, and Ottawa counties of the Blanding's turtle's historical range. This approach to creating Habitat Niche Models was validated by close correlation between the counties identified as having remaining appropriate habitat and the counties from the historical populations in which Blanding's turtles still remain. The potential exists to restore these areas through various means: restoring wetlands, protecting areas near agriculture that are more suitable for nesting, constructing small tunnels under roads and fences, and installing road warning signs to allow for safer migration. With protection and restoration of the habitat, the species may still have a chance to recover and become a stable population without the need for intense management.

This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Chapter 2. Abstract: In 2016 a group of Blanding's Turtles were discovered in a small area in southwestern Nova Scotia near the community of Bangs Falls. The surrounding area was used primarily by the near-by lumber mill for commercial tree harvesting. Blanding's Turtles inhabit various wetland types throughout the year to meet their needs. Thus, the importance of understanding how much of the area was used by the turtles to facilitate protection of the land necessary for their survival. A capture-mark-recapture program has been conducted over four years in the area and morphological data for each individual was recorded. The time and heterogeneity model in the program MARK was used to estimate the number of turtles in the new area as well as to update estimates from the known subpopulations. The Bangs Falls turtles were observed using similar habitat as Blanding's Turtles throughout their range. A total of 500 traps were set and 571 survey hours were done between May and August in 2018 and 2019. Resulting in 154 Blanding's Turtles observations of 66 individuals. They are comparable in weight and length to the Blanding's Turtles found in Pleasant River and McGowan Lake. The number of Blanding's Turtles in the Bangs Falls subpopulationwas estimated to be 77-116 individuals. The total population estimate for Blanding's Turtles in Nova Scotia increased from ~350 individuals to 557 (95% CI: 521-608) individuals. Chapter 3. Abstract: Hatching success in oviparous reptiles varies with environmental factors. The cool climate in Nova Scotia was likely a contributor to low hatching success in Blanding's Turtles compared to other parts of their range (Standing et al.,1999). Nesting data for Blanding's Turtles and environmental factors were recorded. Air temperature was used as a proxy to estimate nest temperatures. Temperature was the best criterion for predicting hatching success and was significantly better than models using variations of degree day. Although the nesting period for Blanding's Turtles in Nova Scotia was similar to those throughout the species geographic range, the mean incubation period was up to 16 days longer and the average emergence rate was low (~42%). The model showed significant increase of hatching success with mean temperature and the data of hatch success over time showed an increasing trend. Rising temperatures will likely lead to increased hatching success of Blanding's Turtles in Nova Scotia for a short period of time, until the temperature rises above that in which they can develop successfully. Additionally, rising temperature will skew sex ratios effectively putting the population at risk of extinction due to limited fertilization opportunities and decreased genetic diversity.

This book was released on 2014-08-04 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Biology and Identification of the Coccidia (Apicomplexa) of Turtles of the World is an invaluable resource for researchers in protozoology, coccidia, and parasitology, veterinary sciences, animal sciences, zoology, and biology. This first-of-its-kind work offers a taxonomic guide to apicomplexan parasites of turtles that enables easy parasite identification, with a summary of virtually everything known about the biology of each known parasite species. It is an important documentation of this specific area, useful to a broad base of readers, including researchers in biology, parasitology, animal husbandry, diseases of wild and domestic animals, veterinary medicine, and faculty members in universities with graduate programs in these areas. There are about 330 turtle species on Earth; many are endangered, a growing number of species are kept as pets, and some are still used as food by humans. Turtles, like other vertebrate animals have many different kinds of parasites (viruses, bacteria, protozoa, worms, arthropods, and others). Coccidiosis in turtles has prevented large-scale turtle breeding, and represents a serious problem in need of control. This succinct and highly focused book will aid in that effort. Offers line drawings and photomicrographs of each parasite from each hosts species Provides methods of identification and treatment Presents a complete historical rendition of all known publications on coccidia (and their closest relatives) from all turtle species on Earth, and evaluates the scientific and scholarly merit of each Provides a complete species analysis of the known biology of every coccidian described from turtles Reviews the most current taxonomy of turtles and their phylogenetic relationships needed to help assess host-specificity and evaluate what little cross-transmission work is available
