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.

Available in PDF, EPUB and Kindle. Book excerpt: Conservation efforts are urgently needed to reduce global biodiversity loss and to keep natural ecosystems intact. Turtles (Order Testudines) are important components of their ecosystems but are one of the most threatened vertebrate groups in the world due to habitat destruction, overexploitation, climate change, invasive species, and disease. To effectively conserve turtles, we need a detailed understanding of their spatial and population ecology, knowledge which is lacking for many declining species. Advancing technological methods are allowing researchers to address these research needs. One technological advancement is the reduction in battery size, which now allows researchers to attach miniature radio transmitters to hatchling and juvenile turtles and track them in their natural habitat. The ability to radio-track the early life stages of turtles allows researchers to study their survival, movements, and habitat needs, which are severely understudied compared to the adult life stages. Battery size reduction also allows for smaller GPS devices which automatically record locations, and which substantially reduces the time and labor required to physically locate individual animals. With this size reduction, researchers have started deploying GPS devices on small turtles; however, this method is in its early stages and requires assessment of its accuracy. Here, I used miniature radio transmitters to study the survival and dispersal of the hatchling stage of two threatened turtle species, the spotted turtle (Clemmys guttata) and Eastern box turtle (Terrapene carolina carolina), in oak savanna habitat of the Upper Midwest. I found hatchlings survival rates of both species from nest emergence through overwintering. Box turtle hatchling survival increased with less nest shade cover, which is associated with warmer nests, shorter incubation durations, and earlier nest emergence dates. Therefore, it is important for managers to maintain a range of ground cover microhabitats in nesting areas so turtles can match nest incubation conditions with current local conditions, while also maximizing hatchling survival. Additionally, I deployed GPS devices on adult spotted and Eastern box turtles to assess the reliability and accuracy of automatically recorded locations on small turtles across a range of habitat types. I found mixed support for habitat affecting accuracy of locations, but the number of satellites received and HDOP had large effects on accuracy of locations recorded by GPS devices. After screening locations based on number of satellites and HDOP, location accuracy was greatly increased. GPS devices are unlikely to be accurate for small, semi-aquatic turtle species but show promise for small, terrestrial turtle species. However, proper testing of GPS devices and methods of filtering their location data are needed to demonstrate their effectiveness when deployed on small turtle species, because unfiltered data can cause bias in ecological calculations, such as home range sizes. Overall, through the use of advancing technologies to track turtles, my research provides rare ecological data on hatchlings of threatened turtle species in the Oak Openings region, while also quantifying the effectiveness of GPS devices on these species.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: As habitat loss and fragmentation are major causes of decline in animal species, studying habitat requirements in these species is a key component of their recovery. I investigated the relationship between landscape composition and habitat use of Blanding's turtles, Emydoidea blandingii, a freshwater turtle threatened by habitat loss and road mortality on most of its Canadian range. In 2010, I conducted a radio-telemetry survey of 44 Blanding's turtles in southern Québec, Canada, and modelled their home range size from land cover proportions measured at many spatial scales. I also used data from a visual survey conducted in 2008 and 2009 to model wetland occupancy of the species at the landscape scale. Home range size of the Blanding's turtle was significantly correlated to landscape composition, and the proportions of agriculture, open water and anthropogenic lands had the strongest relationships with home range size. However, those relationships were weak and the models were unable to predict home range size accurately. At the landscape scale, land cover and road density poorly predicted probability of occurrence, and Blanding's turtles occupied wetlands in both disturbed and natural sites. Management of the species should focus on protecting sites of occurrence with high wetland density, low road density, and sufficient suitable habitat to cover their seasonal movement patterns.

This book was released on 2016 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Urban coastal development has led to major changes in ocean temperatures and habitats along the coastline. These alterations particularly affect coastal ectothermic marine species, such as green sea turtles, Chelonia mydas. This species has been observed north of their geographical range in the eastern Pacific; inhabiting a river and estuary that both have anthropogenically-altered water temperatures and habitats. Passive and active acoustic telemetry was used to determine how green sea turtle movements and habitat use were affected by these anthropogenically-altered sites. Turtles used both sites during the summer months, while during the winter, individuals selected for areas where warm water was discharged from power plants into the river. Further, turtles tracked in the larger river used more area than those tracked in the smaller estuary. Turtles selected habitats associated with manmade structures at both sites and eelgrass beds within the estuary to potentially rest and forage upon.

Haas and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Turtle populations throughout the world are in decline due to the effects associated with anthropogenic disturbances. Northern map turtles in the Upper Niagara River are facing the same effects associated with shoreline development, pollution, and human induced mortality. A biotelemetric study was conducted to understand the population structure, habitat use, and behavior of northern map turtles in the Upper Niagara River. Turtles were trapped, outfitted with radio and sonic transmitters, and tracked from August 2013 until April 2015. Invasive red-eared sliders, which also inhabit the Niagara River were captured and tracked to allow for comparison. This invasive species is a habitat generalist and may have negative impacts on native turtle species. Red-eared sliders were only tagged and tracked when they were sympatric with the northern map turtles. The northern map turtle population is rare and diminishing in the Upper Niagara River. There was no evidence to support sympatric red-eared sliders were threatening the few resident northern map turtles with competition. Northern map turtles generally had larger home ranges and moved greater distances than red-eared sliders. The presence of both species was significantly predicted by surface cover and spent most of their time along developed shorelines. There was no evidence to support a common hibernacula for northern map turtles and one northern map turtle nest was located. Marinas were important components of all the tracked turtle's home ranges and may represent an ecological trap.
