Social-ecological systems resilience in changing rural landscapes of the Midwestern United States
Regional conservation planning is challenged by the complexity of cross-scalar interactions and the limited sphere of influence to deliberately affect social-ecological systems. Human and natural processes are interlinked, non-linear, and emergent. This dissertation has explored the application of …

Fisheries management and flags of convenience
… the need for effective fisheries management and conservation measures. Many states have adopted international instruments or have participated in regional conservation committees to regulate and control fishing activities within their jurisdiction as well as on the high seas. However, compliance …

Many voices, one wilderness : collaborative conservation in the greater Chicago region
There has been a growing recognition in the conservation community that landscape-scale networks of preserves and habitat corridors are needed to adequately protect native biodiversity. While most of the efforts to protect land on this scale have occurred in rural environments dominated by resource …

Habitat Relationships of Breeding Birds in Bottomland Hardwood Forests of the Altamaha River, Georgia
… Neotropical species, as well as the Avian Conservation Score of stations did not closely track habitat variation within mature bottomlands. However, I found that some individual breeding species were sensitive to habitat variation within mature bottomlands. Yellow-throated vireo (Vireo …

The impact of land use on biodiversity in xeric succulent thicket, South Africa
… biodiversity be monitored and measured? . The regional 'conservation landscape' is seen as the protected area plus the land immediately adjoining it, and is viewed as an integrated mosaic of anthropogenic landscapes (land management units), land elements (patches within landscapes). producer …

Vegetational and lepidopteran conservation in rehabilitated ecosystems
… However, their effect on floral and faunal conservation has been poorly documented. Lepidopteran communities, vegetation, and nectar resources were studied on 19 mine sites reclaimed 0-30 years previously and five sites in the surrounding hardwoods in southwestern Virginia. The goals of this …

Conservation priorities and collaboration in the Upper Midwest and Great Lakes Landscape Conservation Cooperative
… change, and human land use, are prompting conservation planning and action at a landscape or regional scale. Historically, natural resource agencies worked within individual jurisdictional boundaries – both geographical boundaries and those boundaries created by differing missions. Yet the …

A Landscape Approach to Grassland Bird Conservation in the Prairie Pothole Region of the Northern Great Plains
… planning tools are a cornerstone of conservation in forested ecosystems, but remain a novel approach in grasslands. In Chapter 2, I develop spatially-explicit habitat models as decision support tools for conservation. I survey birds, measure local vegetation and quantify landscape …

Applying the principles of spatial modelling to the management of biodiversity in the fragmented landscapes of south-western Australia
Biodiversity conservation throughout the world is challenged by the impacts of a changing climate on fragmented landscapes. To mitigate these threats, conservation managers require models which can demonstrate the consequences of both negative impacts and management actions. This need can be …

Estimating leopard density in a coastal protected area of the Western Cape, South Africa
… Protected areas remain the cornerstone of conservation efforts throughout the world but they are not a panacea and recent studies have shown declining populations within many protected areas of South Africa. Efforts to improve leopard conservation are hampered by a lack of reliable and …

Modeling Migration and Citizen-Science Data to Estimate Golden Eagle Abundance in Eastern North America
… animal movements is fundamental to ecology and conservation, yet direct measurement of movements of birds is both challenging and costly. Raptor populations are especially difficult to monitor, but movement models can provide information toward this goal. The golden eagle (Aquila chrysaetos …

Unravelling abiotic and biotic drivers of biodiversity change in local plant and invertebrate communities after 80 years - a re-visitation study on the Studland peninsula.
… BBN models also predicted that the health of the regional metacommunity is of utmost importance in maintaining a healthy local system. I have shown that congruent biodiversity change occurs across diverse plant and insect taxa, and is driven by changes in both abiotic and biotic conditions. These …

Floristic homogenization and impoverishment : herb layer changes over two decades in deciduous forest patches of the Weser-Elbe region (NW Germany)

POPULATION DYNAMICS OF SPECIES RECOVERY: MULTISCALE DEMOGRAPHY IN RESTORED HABITATS
… an important tool for species recovery and conservation. Yet despite the conceptually-appealing lens of “if you build it, they will come” (i.e., the ‘Field of Dreams’ Hypothesis), restoration outcomes are highly variable and generally lack rigorous monitoring and evaluation. Species …

Bycatch and foraging ecology of sea turtles in the Eastern Pacific
… the case in the Eastern Pacific. To establish regional conservation priorities for the mitigation of bycatch, it is essential to first obtain a comprehensive picture of the regional sea turtle bycatch situation. This comprehensive analysis was lacking for the Eastern Pacific; therefore one …
