Bird-vegetation relationships across ten years after thinning in young thinned and unthinned Douglas-fir forests

Creator:: Yegorova, Svetlana
Abstract:: Bird-vegetation associations are a base for bird conservation and management, as well as for predictions of the effects of resource management and climate change on wildlife populations. A recent shift in forest management priorities from timber production to native species' habitat conservation on federal lands has emphasized the need to...

Identifying factors driving sensitivity to fragmentation in forest breeding songbirds

Creator:: Valente, Jonathon J.
Abstract:: Habitat loss and fragmentation are the greatest threats to biodiversity worldwide. Fragmentation impacts landscape configuration, resulting in a larger number of patches that are smaller in size and further apart from one another. Island biogeography and metapopulation theory predict populations in these remnant patches should be smaller, have higher extinction...

Effects of spatial scale and heterogeneity on avian occupancy dynamics and population trends in forested mountain landscapes

Creator:: Frey, Sarah J. K.
Abstract:: Population trends and patterns in species distributions are the major currencies used to examine responses by biodiversity to changing environments. Effective conservation recommendations require that models of both distribution dynamics and population trends accurately reflect reality. However, identification of the appropriate temporal and spatial scales of animal response, and then...

Independent effects of habitat loss and fragmentation on pollination : tropical forest fragmentation alters hummingbird movements and pollination dynamics

Creator:: Hadley, Adam S.
Abstract:: A growing body of work reveals that animal-mediated pollination is negatively affected by anthropogenic disturbance. Landscape-scale disturbance results in two often inter-related processes: (1) habitat loss, and (2) disruptions of habitat configuration (i.e. fragmentation). Understanding the relative effects of such processes is critical in designing effective management strategies to limit...

Trade-offs between management for fire risk reduction and northern spotted owl habitat protection in the dry conifer forests of southern Oregon

Creator:: Comfort, Emily Julia, 1974-
Abstract:: There is a perceived trade-off between fire risk reduction and northern spotted owl habitat protection in dry-conifer forests in southwestern Oregon. Management options for balancing this trade-off need to be sought at the landscape level. Applied landscape ecology suggests three important features to consider are (1) patch size and configuration...

Diversity and abundance of birds across a hardwood gradient in early seral Douglas-fir plantations

Creator:: Ellis, Tana M.
Abstract:: Recent evidence suggests that population declines of some avian species may be driven primarily by reduced quantity and diversity of early-successional habitat on the breeding grounds. Increasing intensity of forest management on private lands and decreased harvest rates on federal lands has resulted in a loss of the diverse early-successional...

Post-breeding habitat selection by songbirds in the headwaters of the Trask River, northwestern Oregon

Creator:: Jenkins, Stephanie R.
Abstract:: Little is known on the importance of riparian areas to birds near small headwater streams in mesic forests. Progress towards understanding limiting factors that affect bird populations has been difficult because of lack of information beyond the breeding period. I compared bird assemblages between headwater riparian and upland areas throughout...

Combined Effects of Intensive Forest Management and Microclimate on Reproduction in a Cavity-Nesting Songbird

Creator:: Jones, Kristin N.
Abstract:: Future scenarios of global climate change rely on large-scale climate envelope models that do not account for local climatic conditions to which organisms most closely respond. Shifts in species distributions and phenology driven by climate change are well-documented, yet we lack a strong understanding of how climate change will influence...

Using Biodiversity Distribution Data to Support Landscape Conservation and Management in Colombia

Creator:: Zárrate-Charry, Diego A.
Abstract:: Global biodiversity decline is primarily driven by habitat loss. Deforestation, the primary driver of terrestrial habitat loss, is increasing worldwide, with the most significant impact in the world biodiversity hotspots. Sadly, specific knowledge of such impacts in biodiversity-rich but data-poor countries are still unknown, and many national and regional narratives...

An examination of climate and land-use change as drivers of population dynamics in breeding birds

Creator:: Kim, Hankyu
Abstract:: Anthropogenic land-cover change and climate change are the major drivers of the steep loss of avian biodiversity in past decades. Loss of avian biodiversity is predicted to result in the reduction of ecosystem services and ecological functions. Identifying avian population changes and the drivers of these trajectories is essential for...
