Download Evaluating Sustainability of Endangered Species Via Simulation Book in PDF, ePub and Kindle
Once abundant in the Texas and Louisiana coastal prairie, currently the Attwater's Prairie Chicken (Tympanuchus cupido attwateri, APC) is close to extinction. Efforts to increase the size of the remaining populations at the Attwater Prairie Chicken National Wildlife Refuge (APCNWR) and the Galveston Bay Prairie Preserve (GBPP) with releases of captive-reared individuals are part of the APC captive- breeding initiative. However, after a decade of yearly releases, the populations are not reaching viable sizes. I analyzed post-release survival data of individuals released at the APCNWR from 1996 to 2005. Results suggest that age at release or date of release had little influence on survival of captive-breed APC. At two weeks post-release, survival estimates (SE) were 0.76 (0.03) for females and 0.82 (0.04) for males. Approximately 50% of the females and 33% of the males died within the first 60 days post-release. Survivorship during the breeding season showed that male survival (0.36) was higher than female survival (0.23). Survivorship from the median release date to beginning of the breeding season was 52% for males and 39% for females. Mean female survival was 155 days, while median survival was 94 days. For males, mean survival was 135 days and the median was 81 days. Results from a stochastic simulation model, which was developed based on the survival analysis of APC on the APCNWR, confirmed that releasing individuals closer to the beginning of the breeding season and sex ratio at release had little effect on population growth. Regardless of the number of individuals released annually, population sizes immediately prior to the release dates were only 110́312% of the population sizes immediately after the release dates. At current mortality rates, simulated APC populations could not sustain themselves even if reproductive parameters were increased to the maximum rates reported for APC, or to the maximum rates reported for the closely related Greater prairie chicken. Based on these results, the APC may face extinction within the next decade unless conservation efforts succeed on increasing reproductive success and greatly reducing mortality rates.

Download The North American Grouse: Their Biology and Behavior Book in PDF, ePub and Kindle
The ten currently recognized species of grouse in North America have played an important role in America's history, from the famous but ill-fated heath hen, a primary source of meat for the earliest New England immigrants, to the ruffed grouse, currently one of the most abundant and soughtafter upland game birds in more than 40 states and provinces. This book summarizes the ecology, reproductive biology, and social behavior of all ten of the extant North American grouse species. It also describes the current status of grouse populations, some of which are perilously close to extinction. The social behavior of grouse is of special biological interest because among these ten species there is a complete mating system spectrum, from seasonally monogamous pair-bonding to highly promiscuous mating patterns. The latter group illustrates the strong structural and behavioral effects of sexual selection resulting from nonmonogamous mating. These influences reach a peak in the development by some grouse species of engaging in mating "leks," arena-like competitions performed by males while attempting to attract fertile females, and also provide opportunities for females to select optimum mating partners. These sexual competitions also promote strong differences evolving in sexual signaling behaviors ("displays") among closely related species. Nevertheless, a relatively high incidence of mating errors and resulting hybridization often occurs in spite of these marked behavioral differences. In addition to a text of 101,000 words, the book includes 16 range maps, 37 line drawings, and 38 photographs by the author, as well as nearly 1,400 literature citations.

Download Bird Conservation Book in PDF, ePub and Kindle
This book brings together scientific evidence and experience relevant to the practical conservation of wild birds. The authors worked with an international group of bird experts and conservationists to develop a global list of interventions that could benefit wild birds. For each intervention, the book summarises studies captured by the Conservation Evidence project, where that intervention has been tested and its effects on birds quantified. The result is a thorough guide to what is known, or not known, about the effectiveness of bird conservation actions throughout the world. The preparation of this synopsis was funded by the Natural Environment Research Council and Arcadia.
