This book was released on 2011 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Population characteristics and habitat preferences of Merriam's pocket mouse (Perognathus merriami), Nelson's pocket mouse (Chaetodipus nelsoni), and the Chihuahuan pocket mouse (C. eremicus) in the Big Bend region of Texas were studied intensively over 26 months. Steep slopes limited the distribution and abundance of Chihuahuan pocket mice but not the other two species. Merriam's pocket mice normally were not present on steep slopes because of the usual occurrence of tall, dense vegetation on these sites, but they did occur there when the understory vegetation was sparse and short and there were either large boulders or fine gravels. Nelson's pocket mice were most abundant on slopes >20%, P. merriami on slopes 3-10%, and C. eremicus on slopes

Book excerpt: The first comprehensive treatment of North American rodents of conservation concern. This action plan summarizes the rodent fauna of North America and provides available information on every rodent taxon that has been considered to be of conservation concern by state, provincial and private conservation agencies and regional experts. It is hoped that the survey provided in this action plan will serve as a common ground for all these parties in drawing up conservation strategies for rodents.

This book was released on 2018 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reintroduction programs for endangered species rarely take competitive interactions between species into account. The endangered Pacific pocket mouse (Perognathus longimembris pacificus) is being reintroduced to parts of its former range where multiple species of native rodents have overlapping diets. The species in this foraging guild compete for seeds both exploitatively and through direct interference interactions. I conducted simulated territory intrusion experiments between P. longimembris and four sympatric species, and determined that pocket mice, the smallest species, are subordinate to all larger species. Body size asymmetries strongly predicted dominance, regardless of phylogenetic relatedness or residency status. Repeated aggressive interactions from resident heterospecifics could lower the chances of reintroduced pocket mice establishing burrows during the critical settlement period. As such, temporarily reducing the density of competing species might be an advisable reintroduction strategy, in combination with other interventions, such as predator exclusion. However, the presence of other members of the seed-foraging guild could have a net benefit for P. longimembris, if pocket mice pilfer from the other species' seed caches more frequently than the other species pilfer from their caches. In a field experiment with dyed seeds I found that cache pilfering occurred infrequently, and a field-enclosure experiment revealed that none of the species use heterospecific scent to find (or avoid) seed caches. A year-long trapping study showed that species utilize spatial niche partitioning, but aggregate the timing of their activity, in areas with high levels of rodent activity. Species differed in the microhabitat they utilized, and although it is not clear if patterns of spatial niche partitioning are due to interspecific interactions or differences in habitat preferences, this study provided clear guidance for habitat management and release site selection for P. longimembris. Collectively, this research suggests that during the initial phases of reintroduction when Pacific pocket mice are establishing their burrows and foraging areas, they will benefit from a reduction of heterospecific competitors, who may displace them from optimal sites. However, during the later growth and regulation phases of a reintroduction, P. longimembris are expected to be able to persist without ongoing management of competitor species.

Available in PDF, EPUB and Kindle. Book excerpt: Admired for its elaborate breeding displays and treasured as a game bird, the Greater Sage-Grouse is a charismatic symbol of the broad open spaces in western North America. Unfortunately these birds have declined across much of their range—which stretches across 11 western states and reaches into Canada—mostly due to loss of critical sagebrush habitat. Today the Greater Sage-Grouse is at the center of a complex conservation challenge. This multifaceted volume, an important foundation for developing conservation strategies and actions, provides a comprehensive synthesis of scientific information on the biology and ecology of the Greater Sage-Grouse. Bringing together the experience of thirty-eight researchers, it describes the bird’s population trends, its sagebrush habitat, and potential limitations to conservation, including the effects of rangeland fire, climate change, invasive plants, disease, and land uses such as energy development, grazing, and agriculture.
