Book Description
Dark (Microdipodops megacephalus) and pallid (Microdipodops pallidus) kangaroo mice are ecological specialists found in arid regions of the Great Basin Desert of the southwestern United States. Historical and current habitat alterations have resulted in disjunct distributions and severely diminished abundance of both species. Phylogenetic and phylogeographic research has discovered unique mitochondrial clades within M. megacephalus (eastern, central, western, and Idaho clades) and M. pallidus (eastern and western clades). Population-genetic analyses targeting the same mitochondrial markers also have found low amounts of maternal gene flow among the clades. However, little is known about population structure and genetic demography (historical and current migration rates, historical and current effective population sizes) within each mitochondrial clade. Herein, nuclear-encoded microsatellite loci were isolated to evaluate the underlying processes that may have molded kangaroo mouse relationships and distributions. Results from population-genetic analyses support previous findings that there are at least three genetically distinct clades within M. megacephalus and two such clades within M. pallidus. Three clades of M. megacephalus appear to have undergone different demographic histories, with little to no migration among clades. The two clades of M. pallidus also appear to have experienced varying demographic change although there has been small but recent migration between them. Additionally, the contemporary effective population sizes of all clades within Microdipodops appear to be low, suggesting that these populations may have difficulty coping with environmental pressures and hence are at risk of extinction. Results of this study are consistent with the recommendation that each Microdipodops clade should be managed as separate units and continually monitored in an effort to conserve these highly specialized taxa.

Rodent Societies
Author: Jerry O. WolffPublisher: University of Chicago Press
ISBN: 0226905381
Category : Science
Languages : en
Pages : 627
Book Description
Rodent Societies synthesizes and integrates the current state of knowledge about the social behavior of rodents, providing ecological and evolutionary contexts for understanding their societies and highlighting emerging conservation and management strategies to preserve them. It begins with a summary of the evolution, phylogeny, and biogeography of social and nonsocial rodents, providing a historical basis for comparative analyses. Subsequent sections focus on group-living rodents and characterize their reproductive behaviors, life histories and population ecology, genetics, neuroendocrine mechanisms, behavioral development, cognitive processes, communication mechanisms, cooperative and uncooperative behaviors, antipredator strategies, comparative socioecology, diseases, and conservation. Using the highly diverse and well-studied Rodentia as model systems to integrate a variety of research approaches and evolutionary theory into a unifying framework, Rodent Societies will appeal to a wide range of disciplines, both as a compendium of current research and as a stimulus for future collaborative and interdisciplinary investigations.

Languages : en
Pages : 188
Book Description
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.
