Can Pollination Networks Withstand Species Loss? An Examination of Plant–Hummingbird Interactions and Their Responses to Experimental Removal of a Flowering Plant Species

Creator:: Leimberger, Kara G.
Abstract:: Global environmental change is causing local extinctions of species. When species depend on one another, as in the mutualistic relationship between plants and pollinators, loss of one interaction partner may cause cascading effects within the community – such as additional extinctions and reduced pollination services. Network theory provides a way...

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...

How sweet is the land? Modeling caloric landscapes for tropical hummingbirds

Creator:: Birkett, Christina Nozomi and Birkett, Nozomi Fukui
Abstract:: Pollination is a critical ecosystem function for sustaining biodiversity. However, pollinators and the services they provide are threatened by landscape-altering anthropogenic activities across the globe. Habitat loss and fragmentation, introduction of invasive species, chemical use, and urbanization have been shown to impact pollination. Pollinator foraging behavior is thought to be...

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...

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...

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...

Investigating synergistic effects of climate and land-use change on the pollination of a tropical plant, Heliconia tortuosa

Creator:: Dowd, Claire E.
Abstract:: Loss of biodiversity due to the effects of climate and land-use change may have implications for pollination services. Disruption to phenological synchronicity or a reduction in the overlap in species distributions of plants and their pollinators may reduce floral resources to pollinators, forcing them to move farther distances. If pollinators...

Interactive effects of silvicultural herbicides and cervid herbivory on early seral plant communities of the northern Oregon Coast Range

Creator:: Stokely, Thomas D.
Abstract:: Intensive forest management (IFM, dense conifer plantings and herbicide applications) may alter the characteristics of early seral plant communities that function as major habitat resources for a host of wildlife species, including cervid herbivores such as Cervus elaphus and Odocoileus hemionus. Such large herbivores can also substantially affect plant community...

Does the Matrix Matter? Using Radio Frequency Identification (RFID) Technology to Examine Hummingbird Movements in Fragmented Tropical Landscapes

Creator:: Jackson, Evan R.
Abstract:: There is increasing evidence that the type of land cover surrounding remnant patches of native habitats (the ‘matrix’) can modify effects of landscape change on biodiversity; thus the traditional idea of dichotomous habitat and non-habitat following island biogeography theory is insufficient in complex landscapes. Matrix type can have dramatic influences...

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...
