A Landscape Approach to Grassland Bird Conservation in the Prairie Pothole Region of the Northern Great Plains
… of the most imperiled ecosystems, and grassland birds have experienced steeper and more consistent declines than any other group of birds in North America. Habitat-based planning tools are a cornerstone of conservation in forested ecosystems, but remain a novel approach in grasslands. In Chapter …

Fynbos connectivity as a function of dispersal distance and the implications for bird conservation in the greater Cape Town area
… connectivity and are thus important factors in conservation. In order to simulate the effect of further fragmentation through habitat loss, patches of increasing size were removed and the results put into context for conservation of both the vegetation types and the dispersing organisms …

A geochemical investigation of the water and sediments of Barber's Pan, North West Province
… is considered most valuable from the aspect of bird conservation, since it is perennial in an area characterized by shallow, seasonally filled pans. Its perennial state is the consequence of anthropogenic intervention in the early part of this century which resulted in the diversion of the Harts …

Influence Of Landscape Spatial Patterns And Land Use Planning On Grassland Bird Habitat Occupancy In Chester County, Pennsylvania
Throughout their range, North American grassland birds as a group have shown steeper and more widespread population declines than any other avian guild. Grassland bird decline corresponds to habitat loss, landscape fragmentation, agricultural intensification, and changes in land management. In …

Examining Avian Communities in Wetlands at Multiple Spatial Extents
… unclear. My research focuses on how the diverse bird communities that rely on wetlands might be affected by changes to their primary habitat and the surrounding landscape. I utilized data from the North American Breeding Bird Survey (BBS) and the National Land Cover Database (NLCD) to develop a …

THE ECONOMIC VALUE OF PRESERVING AND RESTORING MIGRATORY BIRD HABITAT TO RESIDENTS OF THE PACIFIC FLYWAY: A MIXED METHODS STUDY
… place on preserving and restoring migratory bird habitat and is comprised of three chapters: Chapter 1: The Economic Value of Preserving and Restoring Migratory Bird Habitat to Residents of the Pacific Flyway: A Stated Preference Survey Chapter 2: The Value of Conservation: A Focus Group …

Nesting Success of Dickcissel (Spiza americana) and Non-breeding Grassland Bird Use of Northwest Arkansas’ Remnant and Restored Tallgrass Prairies
… populations of North American grassland birds are linked to habitat loss. Tallgrass prairie only covers 3% of its pre-settlement-era range. Small-scale restoration projects attempt to increase acreage for prairie avifauna, and while some breeding grassland species are present at these …

Incubation temperature impacts growth, physiology and survival in nestlings of an open-cup nesting passerine
… the developing offspring. The vast majority of birds require bird-egg contact during incubation to maintain an appropriate environment for embryonic development. Therefore, understanding the ways in which incubation temperature influences variation in nestling growth and physiological …

Forests of the future: ecosystem services in a forest landscape facing significant changes
… always align with objectives for biodiversity conservation so I also explored how forest management affects bird diversity (as an indicator of wider biodiversity), using high-resolution remote sensing data to calculate a number of structural characteristics. Overall, wide-scale landscape …

Using Passive Acoustic Monitoring to Estimate Bird Community Response to Land Management in Southeastern Georgia
… habitat for declining disturbance-dependent birds, such as Bachman's Sparrow (Peucaea aestivalis) and Northern Bobwhite (Colinus virginianus). However, habitat use is likely contingent on specifics of land-use practices, especially those that could alter understory vegetation. My first …

Determining the biases and consistencies in the evidence for conservation
… an anthropogenic extinction crisis and yet conservation efforts are chronically underfunded. There is a tremendous need to act as efficiently as possible to conserve biodiversity – evidence-based approaches are essential to this mission. Biodiversity conservation is undergoing an …

Fantastic Birds and Where to Find Them
… will be corroborated on the ground by conservation collaborators and used to locate new long-term monitoring sites, and acquire new protected areas. Unlike the migratory western Willow Flycatchers, The Nicaraguan Grackle is a residential (non-migratory) bird that occupies more open …

Efficacy of agroecological approaches to ameliorate trade-offs between food production and biodiversity conservation
… between food production and biodiversity conservation. In this thesis, I first review counterfactual techniques (which are needed to elucidate causal relationships and assess impacts credibly) and argue for a step-change in their use at the food-biodiversity nexus, including to answer key …

Land use, food production, and the future of tropical forest species in Ghana
… the greatest threat to tropical forest species. Conservation scientists disagree over the relative importance of two opposing strategies for minimising this threat: enhancing on-farm biodiversity, through wildlife-friendly farming practices, or sparing land for nature by using high-yielding …

Potential collision risk of harriers Circus spp. with wind turbines during breeding season derived from GPS tracking
… the context of assessing the collision risk of birds with wind turbines and may serve as an example for future studies. The results suggest that MoH exhibit a rather low collision risk, as long as core breeding areas are kept free from wind farms. Raising the MRTH of wind turbines was shown to …

Money for something? Investigating the effectiveness of biodiversity conservation interventions in the Northern Plains of Cambodia
Despite substantial investments in biodiversity conservation interventions over the past two decades there is relatively little evidence about whether interventions work, and how they work. Whether an intervention is deemed to “work” depends upon how goals are defined and then measured, which is …

IMPROVING CONSERVATION IMPACT THROUGH PRIORITY-SETTING AND EVALUATION
