Land ownership and forest cover in the Oregon Coast Range : spatial pattern and social ground-truthing

Creator:: Stanfield, Brooks J.
Abstract:: We use qualitative and quantitative methods to explore social and spatial relationships between land ownership and forest cover in the Oregon Coast Range. Using a Geographic Information System (GIS) and regression analysis, we tested for spatial relationships between the structure of land ownership and forest cover across 66 watersheds in...

The effects of alternative future development scenarios on ecological processes and social-ecological resilience in Central Oregon

Creator:: Duncan, James A.
Abstract:: This research sought to explore the implications of different tenure regimes for both landscape-level ecological processes and the overall resilience of a social-ecological system in Central Oregon. The purchase by an investor of former industrial timberlands known as the Bull Springs tract raised the specter of dispersed residential development on...

The ecological legacy of Indian burning practices in southwestern Oregon

Creator:: Carloni, Kenneth R.
Abstract:: Two research questions are posed: (1) How have ecosystem conditions changed through time in southwestern Oregon? (2) How have culture-driven and climate-driven processes contributed to ecosystem change in southwestern Oregon? A brief introduction to the Little River study area is followed by a cultural and ecological history of the watershed....

Influence of wetland landscape structure of shorebirds wintering in an agricultural valley

Creator:: Taft, Oriane Williams
Abstract:: Understanding how wetland birds use habitat is pivotal to developing successful and beneficial conservation strategies. Although it has been an ardent topic in forest research for some time, how species interact with the spatial patterning of habitat across a landscape (i.e., landscape structure) has been more or less neglected in...

Assessing landscape complexity using remotely sensed and field based measurements : does landscape complexity drive leafroller parasitism rates on Oregon caneberry farms?

Creator:: Winfield, Tammy L.
Abstract:: Landscape heterogeneity is thought to differ among farm management types (i.e. organic and conventional), and this difference is hypothesized to result in variations in pest control by natural enemies. However, it is unclear if these variations in pest control are driven by landscape structure or by farm management practices themselves....

The influences of habitat structure and landscape heterogeneity on African buffalo (Syncerus caffer) group size in Hluhluwe-Imfolozi Game Reserve, South Africa

Creator:: Dora, Cathleen Anna
Abstract:: This study aimed to connect habitat and landscape scale variation, through time and space, to wildlife population dynamics. I studied African buffalo (Syncerus caffer) group size according to habitat structure, landscape heterogeneity, forage quality, and water availability in Hluhluwe-iMfolozi Game Reserve, South Africa. I used two approaches to study grouping...

Linking greater sage-grouse habitat use and suitability across spatiotemporal scales in central Oregon

Creator:: Freese, Mark T.
Abstract:: Greater Sage-grouse (Centrocercus urophasianus) habitat research has historically focused on fine-scale (0.007 - 0.032 ha) vegetation structure and composition immediately surrounding sites selected by birds. However, little work has evaluated vegetation attributes important for Greater Sage-grouse at a landscape-scale or identified landscape attributes that influence habitat use patterns. Habitat use...

Drought, dispersal, and community dynamics in arid-land streams

Creator:: Bogan, Michael T.
Abstract:: Understanding the mechanisms that regulate local species diversity and community structure is a perennial goal of ecology. Local community structure can be viewed as the result of numerous local and regional processes; these processes act as filters that reduce the regional species pool down to the observed local community. In...

Biogeographic and experimental evidence for local scale dispersal limitation in central Panamanian forest birds

Creator:: Moore, Randall Phillips, 1965-
Abstract:: I examined the avian biogeography of the islands of Lago Gatun, Panama, in an effort to better understand the effects of forest fragmentation in this biodiverse region, and specifically to understand the importance of fragment isolation and the mechanism behind its effects on tropical bird distribution. I combined exhaustive surveys...

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...
