Many research studies have characterized the primary productivity of tropical forests and contributed to highlighting the complexity of underlying drivers of the ecological system. However, few studies have explored how productivity changes across multiple scales and how the dri…
ln Southeast Asia, biodiversity-rich forests are lost to logging, tree monocultures, and mining at an unprecedented rate. Impacts of these land-use changes are largely unknown for freshwater biodiversity. Here, I addressed questions pertinent to understanding impacts of land-use…
The political economic pressures of development contribute to unsustainable environmental practices in developing countries, and marginalize civil society participation. This dissertation looks at the following countries where policymakers are faced with strong incentives to fos…
The marine aquarium trade has played an important role in shaping the ecological state of coral reefs in Indonesia and much of the Asia-Pacific. The use of cyanide by ornamental fishers in Buleleng District, Bali, in the 1980s and 1990s has resulted in a precipitous decline in t…
While the behavior and ecology of the Kloss's gibbon (Hylobates klossii), a species endemic to the Mentawai Islands of Indonesia, have been studied in some detail, its relationship to other gibbon species has remained poorly understood, as have any patterns of intraspecific vari…
In a world of declining biodiversity, Indonesia stands out in particular due to the richness of its diversity, and because of the rapidity of its decline. In response to this decline, Indonesia ratified the Convention on Biological Diversity, and additional protected areas have …
Indonesia is a center of marine biodiversity and its coral reef ecosystems are some of the most threatened worldwide. To help address questions related to the ecology and conservation of these important reefs, I applied a population genetic approach to understand the connectivit…
This study focuses on the conflict that emerged in the 1930s and 1940s between the British colonial government officials and the African farmers in Vihiga, Western Kenya, over approaches to land management. The colonial state was more than convinced that unprecedented soil erosi…
This dissertation is organized in four chapters that deal with different aspects of my long-term studies of migratory raptors, vultures, and wading birds, in central Veracruz, Mexico, during the course of three spring and ten fall seasons (1991-2004). I examine several character…
The eastern imperial eagle (Aquila heliaca; EIE) is a large raptor found throughout central Europe and Asia. The biology of EIEs is currently of considerable conservation interest because the species experienced rapid population declines during the middle of the twentieth centur…
This dissertation investigated the ecological and cultural interconnections between Tonkean macaques (Macaca tonkeana ) and human residents of the Lindu valley in Lore Lindu National Park. The research had two major foci. The first examined how Tonkean macaques respond, in terms…
The Tangkoko Nature Reserve in North Sulawesi, Indonesia contains one of the largest remaining populations of critically endangered Sulawesi black macaques (Macaca nigra ) and experiences a high rate of foreign and local ecotourism. Analyses of behavioral interactions between to…
Local ecological knowledge systems are dynamic expressions of perceiving and understanding the world, which have historically made and continue to make valuable contributions to ecology and conservation science. This dissertation examines the process and outcomes of integrating …
This study analyzed changes in livelihoods before and after tourism development at Khwai, Mababe and Sankoyo villages in the Okavango Delta. Specifically, it analyzed how people interacted with species like giraffe (Giraffa camelopardalis ), sable antelope (Hippotragus niger ) a…
The Black Rock Forest is a 3,785-acre wilderness area whose richly forested landscape represents the splendor of the Hudson Valley Region of New York State. Although originally intended to become the home of wealthy banker James Stillman, it was his son Ernest whose love of cons…
Conservation science and practice are being transformed. Integrative strategies for informed action must be developed in the context of specific, problematic and complex situations. In addressing this challenge, two basic questions are asked: (i) how can we better understand the…
The goal of this study was to examine attitudes toward the environment in the Middle East. The current study assessed the relationship between severity of environmental problems and attitudes toward the environment in Bahrain, Jordan, and Saudi Arabia. It studied the extent to w…
This study evaluates the positive and negative impacts of strict protected area designation on the livelihoods and socioeconomic wellbeing of a resident community living within the boundaries of a protected area, and explores how these impacts are distributed across different co…
