Paperback. Condizione: New. Ecology of Willow Flycatchers (Empidonax traillii) in the Sierra Nevada, California: Effects of Meadow Characteristics and Weather on Demographics Abstract: Population declines in songbirds are often attributed to regional habitat loss and fragmentation caused by landuse practices, which might be further aggravated by climate change. These concerns are particularly evident in the Intermountain West, where riparian areas are considered a priority for conservation because of predicted reductions in winter precipitation and increases in spring temperatures. These climatic changes might increase the susceptibility of species reliant on riparian areas to regional extirpation from loss of habitat. The Willow Flycatcher (Empidonax traillii) is a California species of concern because of precipitous population declines in the past three decades. In 1997, we established a longterm research program to determine population demographics and the effects of weather events and regionalscale meadow distribution and vegetative structure on nesting success of Willow Flycatchers. We monitored territory establishment and reproductive success of 786 territories and 850 nests in meadows distributed south and north of Lake Tahoe, California, from 1997 to 2008. We documented near extirpation of Willow Flycatchers south of the lake and a declining trend in the number of territories north of the lake. Latespring storms and low temperatures at the start of the breeding season reduced the length of the breeding season, affecting the ability of Willow Flycatchers to renest. Nest age better predicted nest survival than meadowscale landscape and weather variables. Although weather parameters were not significant as a direct influence on nest survival analyses, our results suggested a weak negative relationship with increased snowfall. For our nestscale model evaluation, overnest vegetation concealment increased nest survival in large meadows but had little effect on nest survival in smaller meadows. Evidence from our dispersal data implied that Willow Flycatchers in our study regions had high natal and breedingsite fidelity, which suggests that recruitment across these study regions might be limited. Given that we observed a declining population trend in the South Tahoe region, our results suggest that populations in the South Tahoe region may not rebound. Compared with a reference site that we established in 2003, where the population of Willow Flycatchers appeared to be stable, reproductive success was lower at our longterm sites. We suggest that differences in breedingseason length and the quality of habitat in meadows contributed to lower reproductive success and to the observed population declines.(Ecologia de Empidonax trailli en la Sierra Nevada, California: Efectos de las Caracteristicas de las Praderas y del Clima en la Demografia).…

Paperback. Condizione: New. A book that emphasized the concept of wildlife habitat for a generation of students and professionals is now available to even more readers."Habitat" is probably the most common term in ecological research. Elementary school students are introduced to the term, college students study the concept in depth, hunters make their plans based on it, nature explorers chat about the different types, and land managers spend enormous time and money modifying and restoring habitats. Although a broad swath of people now have some notion of what habitat is, the scientific community has by and large failed to define it concretely, despite repeated attempts in the literature to come to meaningful conclusions regarding what habitat is and how we should study, manipulate, and ultimately conserve it.Wildlife Habitat Conservation presents an authoritative review of the habitat concept, provides a scientifically rigorous definition, and emphasizes how we must focus on those critical factors contained within what we call habitat. The result is a habitat concept that promises long-term persistence of animal populations. Key concepts and items in the book include. Rigorous and standard conceptual definitions of wildlife and their habitat. A discussion of the essential integration of population demographics and population persistence with the concept of habitat. The importance of carryover and lag effects, behavioral processes, genetics, and species interactions to our understanding of habitat. . An examination of spatiotemporal heterogeneity, realized through fragmentation, disruption to eco-evolutionary processes, and alterations to plant and animal assemblages. An explanation of how anthropogenic effects alter population size and distribution (isolation), genetic processes, and species diversity (including exotic plants and animals). Advocacy of proactive management and conservation through predictive modeling, restoration, and monitoring.Each chapter is accessibly written in a style that will be welcomed by private landowners and public resource managers at local, state, and federal levels. Also ideal for undergraduate and graduate natural resource and conservation courses, the book is organized perfectly for a one-semester class.Published in association with The Wildlife Society.…
