Available in PDF, EPUB and Kindle. Book excerpt: Historically the management of public lands from a multiple use perspective has led to a system that emphasizes those habitat components or faunal elements that primarily resulted in some sort of definable economic value. While this often benefitted other species that were not even considered in the original prescriptions, it also negatively impacted others. We no longer can afford to take this simplistic view of ecosystem management. We need to use a more holistic approach where ecological landscapes are considered as units, and land management practices incorporate all elements into an integrated policy. This includes examining the impacts of proposed land uses on amphibian, reptile, and small mammal populations.

This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Human-caused destruction of xeric habitats in Florida that support gopher tortoises (Gopherus polyphemus Daudin) is occurring at a rapid rate. One conservation strategy that has been used for numerous taxa is translocation. The effects of translocation on the health, reproductive activity, and movements of translocated and resident telemetered individuals was evaluated for a population of gopher tortoises in central-Florida from 2001 to 2004. Only one of the 13 individuals released left the site during the study. The home range estimates of resident individuals were not significantly different before and after the release of the translocated individuals on the site, and all mean home ranges fit within the range of estimates reported in the literature for natural populations of gopher tortoises. Habitat use of several individual resident gopher tortoises was significantly different after the translocation events. The degree that the home ranges of the residents were overlapped by other individuals in the study was not significantly different. The spatial locations of the home ranges of resident and translocated individuals were significantly different. There was evidence of reproduction for both resident and translocated females a year after the release of the translocates. The body condition of the resident individuals was higher at the end of the study relative to the start, although this may be explained by other factors. This study illustrates some of the problems associated with studies designed to assess translocation success, namely the lack adequate baseline data for the population and the challenge of balancing the sample sizes necessary for acceptable statistical power with the mechanics of translocation. The results of this study suggest that translocation is a potentially useful conservation strategy, although there are other potential consequences of translocation that need to be considered prior to its implementation.

This book was released on 2021 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Author's abstract: Gopher tortoises (Gopherus polyphemus) are a threatened, keystone species that play important roles in upland habitats throughout the southeastern United States. Climate change could have diverse and strong effects on the fecundity and population demographics of gopher tortoises, as they are long-lived reptiles that rely on environmental temperatures for thermoregulation and sex determination. I used a population of translocated gopher tortoises at Nokuse Plantation, located in the panhandle of Florida, as a common garden experiment to assess whether plasticity of several nesting behaviors (i.e., nest temperature, depth, and orientation) and components of fecundity (i.e., clutch size, egg size, hatching success) might compensate for changes in environmental conditions. I compared nest characteristics among translocated females (from across the state of Florida) and examined how multiple measures of environmental distance, such as difference in warm season temperature between the translocation and origin sites, impacted aspects of fecundity. I found that tortoises did not exhibit plasticity and did not adjust their nesting behaviors in response to novel conditions. Tortoises that originated from climates that were more dissimilar from that of the translocation site placed their nests at different locations within the burrow apron, under differing amounts of canopy cover, and at different depths. Environmental distance of translocation also impacted hatching success, although there was no direct impact of nest site selection on hatching success, suggesting that differences in hatching success due to female origin are more a consequence of physiology (e.g., developmental processes) than female behavior. Although there was a high degree of variability in the direction of the effect of environmental distance – i.e., whether tortoises from more or less similar climates had greater hatching success – these results may indicate a strong degree of local adaptation that is still apparent even several years after translocation. These findings suggest that gopher tortoises may not be resilient to impending environmental changes, and behavior plasticity should not be expected. Effects on nest site selection, incubation temperatures, and hatching success suggest that translocation guidelines should consider climate differences when selecting relocation sites.

This book was released on 2016 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Habitat loss, fragmentation, and degradation have led to an estimated 80% range-wide decline of gopher tortoise (Gopherus polyphemus) populations across the Southeastern Coastal Plain. Recently, the gopher tortoise was identified as a candidate for listing under the Endangered Species Act in the eastern part of its range. To support an adaptive landscape planning and decision framework for gopher tortoise conservation, I examined the population dynamics and movement patterns of four gopher tortoise populations on a large private reserve in southwestern Georgia, where tortoises were previously marked/recaptured from 1995-2000. It is critical to understand how tortoise populations vary in space and time at large spatial and temporal scales to protect a long-lived species, such as the gopher tortoise, into perpetuity. With further understanding of the long-term population ecology and movement patterns, we can better evaluate the roles of emigration and survival within populations to inform reserve design and decision analysis for the species' conservation.
