Using a species-centered approach to examine patterns and drivers of avian species richness in the Rogue Basin, Oregon, A 'bird's eye view' : using a species-centered approach to examine patterns and drivers of avian species richness in the Rogue Basin, Oregon

Creator:: Halstead, Katherine E.
Abstract:: The combined effects of habitat loss, degradation, and fragmentation pose a serious threat to Earth's biodiversity, imperiling even relatively common species. 'Habitat' is necessarily a species-specific concept, and investigations of bird diversity relationships and subsequent efforts to prioritize conservation areas, are challenged by the difficulty of estimating complex habitat gradients...

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...

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...

Are Bird Habitat Associations Consistent Across Space and Time?

Creator:: Rousseau, Josée S.
Abstract:: The concept of the fundamental niche is frequently used in ecology to define the set of environmental conditions needed by a species to survive and reproduce (Hutchinson 1957). In contrast, the realized niche constitutes the locations where a species actually occurred, which is a function of both the environmental (abiotic)...

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...

Balancing Timber Production and Conservation in the Oregon Coast Range: an Examination of the Response by Birds and Bird-induced Ecosystem Services to Forest Management at Multiple Scales

Creator:: Harris, Scott H.
Abstract:: Society derives many critical and irreplaceable values from forests. With a growing global human population and rates of consumption, forests are under increasing pressure to provide all these values simultaneously. To meet societal demands for wood products, tree plantations are becoming increasingly common and are replacing native forests. Yet, forests...

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...

Tradeoffs and Synergies among Wild Ungulates, Early Successional Plant Communities and Management Intensification in Forest Plantations of the Oregon Coast Range

Creator:: Stokely, Thomas D.
Abstract:: As the global demand for natural resources increases, more land will be intensively managed for the production of commodities such as timber, with potential consequences to biodiversity, ecological functioning and ecosystem services provided to society. Although there is strong consensus that intensive land management practices can negatively affect biodiversity, less...

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...
