This book was released on 2019-04-26 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 40 or so species of beach-loving plovers (genus Charadrius) comprise a diverse group of shorebirds found around the world. Most of these species are challenged by changing climates and other human-related development activities, yet they provide key insights into basic ecological and evolutionary processes. The expert international contributors take a comparative approach, presenting examples from many worldwide plover studies and synthesizing the group’s most pressing and important topics. The book further presents an emphasis on full life-cycle biology, including the importance of examining migratory connectivity issues, even for non-migratory plovers.

Download or read book Nesting and Postfledging Ecology of Neotropical Migrant Songbirds in Missouri Forest Fragments written by Julianna Marie Arntzen Jenkins and published by . This book was released on 2016 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: The postfledging period, after fledging and before migration, is a critical stage for Neotropical migrant songbirds. The postfledging period encompasses an interval of high mortality that can greatly affect population growth models. Several species of mature forest nesting birds have been documented using very different habitat late in the summer, suggesting shifting habitat requirements during the postfledging period. I monitored nests and used radio-telemetry to observe postfledging juveniles of two species, the Ovenbird (Seiurus aurocapilla) and Acadian Flycatcher (Empidonax virescens), which overlap in nesting territories but differ in natural history. Monitoring was done in Missouri mature-forest fragments from 2012 to 2015. I document juvenile ecology and investigate how risks and habitat selection vary from the nesting period to the postfledging period and observe if trends are preserved across guilds. In chapter 1, I describe postfledging juvenile behavior, parental care, and space use. I used generalized linear mixed models within an information theoretic framework to evaluate the relationship of postfledging movement rates to intrinsic, temporal, and local-habitat variables. Fledgling Acadian Flycatchers (n = 45) utilized more vertical space and had 59% smaller natal home-ranges than fledgling Ovenbirds (n = 62). I found strong positive effects of age on movement distances for both study species and found a negative effect of foliage density on Ovenbird movements. My work provides a new source of support for the theory that habitat quality for postfledging Ovenbirds and other ground foraging forest songbirds increases with forest understory or groundcover foliage density. The few postfledging survival rates published to date are as variable as nest survival across regions and fragmentation gradients. However, factors that negatively impact nest survival may benefit postfledging individuals or not be as important postfledging. In chapter 2, I used an information-theoretic approach to determine support for effects of intrinsic, temporal, edge and local vegetation factors on survival in each stage and examined the potential effect of the resulting survival estimates on population growth. I did not find support for survival tradeoffs in habitat between stages. Nest period survival was comparable between species (~0.30) while postfledging period survival was 43% lower for Ovenbirds (~0.50) than for Acadian Flycatchers (~0.89). Projected population growth was sensitive to estimates of postfledging survival in our populations. In chapter 3, I compared resource selection for nest-sites and by postfledging juveniles using Bayesian discrete choice resource selection models evaluated with an information theoretic approach. Resource selection models indicated that Acadian Flycatcher habitat selection requirements relaxed from nesting to postfledging, with only canopy cover positively contributing to selection postfledging. Resource selection for Ovenbirds shifted from a preference for open understory mature forest nest sites, to increased selection for high understory foliage density and sapling density. Habitat management based upon nesting requirements would likely be sufficient for postfledging Acadian Flycatchers, but insufficient for postfledging Ovenbirds.

Download or read book Ecology Conservation and Management of Grouse written by Brett K. Sandercock and published by Univ of California Press. This book was released on 2011-10-04 with total page 746 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grouse—an ecologically important group of birds that include capercaillie, prairie chickens, and ptarmigan—are distributed throughout the forests, grasslands, and tundra of Europe, Asia, and North America. Today, many grouse populations are in decline, and the conservation and management of these charismatic birds is becoming a global concern. This volume summarizes current knowledge of grouse biology in 25 chapters contributed by 80 researchers from field studies around the world. Organized in four sections—Spatial Ecology, Habitat Relationships, Population Biology, and Conservation and Management—the chapters offer important insights into spatial requirements, movements, and demography of grouse. Much of the research employs emerging tools in ecology that span biogeochemistry, molecular genetics, endocrinology, radio-telemetry, and remote sensing. The chapters explore topics including the impacts of climate change, energy development, and harvest, and give new evidence for life-history changes in response to human activities.

Download or read book Golden winged Warbler Ecology Conservation and Habitat Management written by Henry M. Streby and published by CRC Press. This book was released on 2016-10-26 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Golden-winged Warblers (Vermivora chrysoptera) are migratory songbirds that breed in temperate North America, primarily in the Great Lakes region with remnant populations throughout the Appalachian Mountains, and winter in Central and northern South America. Their breeding range has contracted dramatically in the Appalachian Mountains and many populations have dramatically declined, likely due to habitat loss, competition and interbreeding with Blue-winged Warblers (Vermivora pinus), andglobal climate change.. As a result of population declines in much of the eastern portion of their breeding range, Golden-winged Warblers are listed as endangered or threatened in 10 U.S. states and in Canada and have been petitioned for protection under the U.S. Endangered Species Act. Published in collaboration with and on behalf of The American Ornithological Society, this volume in the highly-regarded Studies in Avian Biology series compiles extensive, current research on Golden-winged Warblers and summarizes what is known and identifies many remaining unknowns, providing a wealth of peer-reviewed science on which future research and listing decisions can be based.

Download or read book Nest Site Selection In Hudsonian Godwits written by Rose Jennetta Swift and published by . This book was released on 2016 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: The choice of where to nest has enormous fitness consequences for individuals and, when scaled up, can even affect population demography. Nest site selection in birds is, therefore, guided by a wide variety of proximate and ultimate factors, including protection from predators, access to favorable microclimates, proximity to food resources, and costs/benefits stemming from interactions with neighboring con- and hetero-specifics. Nevertheless, the features associated with, cues used to identify, and availability of favorable nest sites may be changing rapidly with accelerating human development and climate change, especially in the Arctic and sub-Arctic. I investigated how habitat characteristics, predation risk, and proximity to human disturbance (i.e., roads) influenced nest site selection for the Hudsonian Godwit (Limosa haemastica). First, I identified habitat characteristics most associated with nests of Hudsonian Godwits in two breeding populations - Beluga River, Alaska and Churchill, Manitoba. I was particularly interested in habitat attributes that are (or will be) strongly impacted by climate change and human development. Second, I assessed the spatial pattern of nests in Beluga River, Alaska to evaluate if there was evidence of aggregation and then determined the extent to which nest location and fate were associated with predation risk and habitat features. Hudsonian Godwits displayed strong preferences for certain habitat features when selecting nest sites, with individuals preferring nest sites with less bare ground and more graminoid and tall shrubby cover than random locations. Nest site preferences were relatively similar in the two study populations, though birds in Churchill also preferred to nest near shallow water. Given the demonstrated preferences of nesting godwits, our study suggests that habitat degradation due to grubbing by overabundant Snow Geese (Chen caerulescens) and changing climate will reduce the suitability and availability of habitats for breeding godwits. My study also provides evidence that, despite the importance of nesting habitat attributes, additional factors must be guiding nest site selection because nests of godwits were clustered within bogs. Because the spatial aggregation of nests was not explained by either underlying patchiness in habitat or by predation risk, I suggest that clustering may be related to social cues. Therefore, understanding behavioral processes can be as important as ecological requirements for habitat selection.

Available in PDF, EPUB and Kindle. Book excerpt: This practical handbook of reptile field ecology and conservation brings together a distinguished, international group of reptile researchers to provide a state-of-the-art review of the many new and exciting techniques used to study reptiles. The authors describe ecological sampling techniques and how they are implemented to monitor the conservation status and population trends of snakes, lizards, tuatara, turtles, and crocodilians throughout the world. Emphasis is placed on the extent of statistical inference and the biases associated with different techniques and analyses. The chapters focus on the application of field research and data analysis for achieving an understanding of reptile life history, population dynamics, movement patterns, thermal ecology, conservation status, and the relationship between reptiles and their environment. The book emphasises the need for thorough planning, and demonstrates how a multi-dimensional approach incorporates information related to morphology, genetics, molecular biology, epidemiology, statistical modelling, animal welfare, and biosecurity. Although accentuating field sampling, sections on experimental applications in laboratories and zoos, thermal ecology, genetics, landscape ecology, disease and biosecurity, and management options are included. Much of this information is scattered in the scientific literature or not readily available, and the intention is to provide an affordable, comprehensive synthesis for use by graduate students, researchers, and practising conservationists worldwide.
