This book was released on 2004 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: We performed bird and butterfly surveys from 1996 to 2004, and Yellow Warbler nest surveys in 2002 and 2004. Bird and butterfly surveys took place in two regions of the Greater Yellowstone Ecosystem. The northern region, or "Gallatins", consisted of the northwest corner of Yellowstone National Park and the western edge of Gallatin National Forest. The southern region, or "Tetons", included Grand Teton National Park extending slightly into Bridger-Teton National Forest. The bird and butterfly surveys (25 sampling sites in each region) were used to relate species composition to montane meadow types, which we classified along a hydrological gradient using remotely-sensed satellite imagery. We also related shifts in species composition to temporal changes in the Normalized Difference Vegetation Index (NDVI), which we used as a surrogate measure of climate (e.g., temperature and precipitation). NDVI measures were derived from the same satellite imagery used to construct the habitat classification. We found that Gallatin butterflies in mesic (as opposed to dry or wet) meadows exhibited concurrent shifts in species composition correlated with NDVI between the years 1997 and 2000, and between the years 1998 and 2000. Yellow Warbler nest surveys were performed only in the Tetons and were restricted to willow habitats. We hypothesized that waterway density within each nest territory would indirectly lower nest success by attracting high densities of garter snakes, which would then opportunistically prey on warbler nests. We used a recently published method of nest success analysis known as logistic-exposure, which is a logistic regression technique slightly modified via its logit link function. We found a significant negative effect of waterway density on nest success in our Pacific Creek study site, with a parameter estimate of -0.048 and a 95% confidence interval of [-0.086, -0.012]. We concluded that butterflies in the Gallatins responded at the community level to changes in vegetation within certain habitat types, which in turn reflected general climate patterns over specific time periods. We also concluded that waterway density can be used as an indirect predictor of nest success in Yellow Warblers, provided other predators are taken into account.

This book was released on 1999 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our results indicate that similarity is not high between bird communities in the two study areas, and it is difficult to use composition and abundance data from one study area to classify the meadow types in the other area. A multiple regression analysis was used to test the predictability of bird communities in the two study areas based upon remotely sensed habitat classifications and landscape and habitat variables. The analyses of the meadow type variable and other landscape and habitat variables produced mixed results.

Book Synopsis Response of Songbirds to Riparian Willow Habitat Structure in the Greater Yellowstone Ecosystem by : Brian F. M. Olechnowski
Download or read book Response of Songbirds to Riparian Willow Habitat Structure in the Greater Yellowstone Ecosystem written by Brian F. M. Olechnowski and published by . This book was released on 2008 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: We compared the structure of riparian willow (Salix spp.) habitat and songbird diversity across two regions of the Greater Yellowstone Ecosystem: Gallatin National Forest and Yellowstone National Park in the north and Grand Teton National Park in the south. The average height of willows was greater (151 vs. 65.9 cm) in the Teton region, and the average density of willows was greater (45.2 vs. 26.1%) in the Gallatin. The average height of willows was the most important variable explaining songbird species richness and abundance across these two regions. Songbird richness and abundance was greater (6.1 vs. 3.1 species; 11.7 vs. 5.6 individuals) in the Teton region. Larger patch size in the Tetons could be a factor contributing to the higher level of diversity but was not statistically significant. Individual species responses to habitat structure varied based on the nesting height preference of the species. Species that nest above the ground or in taller vegetation had abundance positively correlated with average willow height (Yellow Warbler [Dendroica petechia] P

Book Synopsis Songbird Response to Increased Willow (Salix Spp.) Growth in Yellowstone's Northern Range by : Lisa Marie Baril
Download or read book Songbird Response to Increased Willow (Salix Spp.) Growth in Yellowstone's Northern Range written by Lisa Marie Baril and published by . This book was released on 2011 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: After nearly a century of height suppression, willows (Salix spp.) in the northern range of Yellowstone National Park, USA, are increasing in height growth as a possible consequence of wolf (Canis lupus) restoration, climate change, or other factors. Regardless of the drivers, the recent release of this rare but important habitat type could have significant implications for associated songbirds that are exhibiting declines in the region. Our objective was to evaluate bird response to releasing willows by comparing willow structure and bird community composition across three willow growth conditions: height suppressed, recently and previously tall willows exhibited high and similar vertical structure, but released willows were significantly lower in horizontal structure. Suppressed willows were significantly shorter and lower in horizontal cover than released or previously tall willows. Bird richness increased along a gradient from lowest in suppressed to highest in previously tall willows, but abundance and diversity were similar between released and previously tall willows, despite lower horizontal cover in the released condition. Common Yellowthroat (Geothylypis trichas) and Lincoln's Sparrow (Melospiza lincolnii) were found in all three growth conditions; however, Yellow Warbler (Dendroica petechia), Warbling Vireo (Vireo gilvus), Willow Flycathcer (Empidonax traillii), and Song Sparrow (Melospiza melodii) were present in released and previously tall willows only. Wilson's Warbler (Wilsonia pusilla) was found in previously tall willows only, appearing to specialize on tall, dense willows. The results of our a priori habitat models indicated that foliage height diversity was the primary driver of bird richness, abundance, and diversity. These results indicate that vertical structure was a more important driver of bird community variable than horizontal structure and that riparian and willow-dependent bird species have responded positively to increased willow growth in the region.

Download or read book Conservation by Proxy written by Tim Caro and published by Island Press. This book was released on 2010-06-23 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vast scope of conservation problems has forced biologists and managers to rely on "surrogate" species to serve as shortcuts to guide their decision making. These species-known by a host of different terms, including indicator, umbrella, and flagship species-act as proxies to represent larger conservation issues, such as the location of biodiversity hotspots or general ecosystem health. Synthesizing an immense body of literature, conservation biologist and field researcher Tim Caro offers systematic definitions of surrogate species concepts, explores biological theories that underlie them, considers how surrogate species are chosen, critically examines evidence for and against their utility, and makes recommendations for their continued use. The book clarifies terminology and contrasts how different terms are used in the real world considers the ecological, taxonomic, and political underpinnings of these shortcuts identifies criteria that make for good surrogate species outlines the circumstances where the application of the surrogate species concept shows promise Conservation by Proxy is a benchmark reference that provides clear definitions and common understanding of the evidence and theory behind surrogate species. It is the first book to review and bring together literature on more than fifteen types of surrogate species, enabling us to assess their role in conservation and offering guidelines on how they can be used most effectively.
Book Synopsis Conservation Biology for All by : Navjot S. Sodhi
Download or read book Conservation Biology for All written by Navjot S. Sodhi and published by OUP Oxford. This book was released on 2010-01-08 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conservation Biology for All provides cutting-edge but basic conservation science to a global readership. A series of authoritative chapters have been written by the top names in conservation biology with the principal aim of disseminating cutting-edge conservation knowledge as widely as possible. Important topics such as balancing conversion and human needs, climate change, conservation planning, designing and analyzing conservation research, ecosystem services, endangered species management, extinctions, fire, habitat loss, and invasive species are covered. Numerous textboxes describing additional relevant material or case studies are also included. The global biodiversity crisis is now unstoppable; what can be saved in the developing world will require an educated constituency in both the developing and developed world. Habitat loss is particularly acute in developing countries, which is of special concern because it tends to be these locations where the greatest species diversity and richest centres of endemism are to be found. Sadly, developing world conservation scientists have found it difficult to access an authoritative textbook, which is particularly ironic since it is these countries where the potential benefits of knowledge application are greatest. There is now an urgent need to educate the next generation of scientists in developing countries, so that they are in a better position to protect their natural resources.
