A meta-analysis of the value of marine protected areas for pelagic apex predators
(2015)A vast range of theoretical and empirical studies now suggests that MPAs can conserve marine biodiversity and, under some circumstances, increase fishery yields. However, despite the importance of pelagic apex predators ... -
A Preliminary Assessment of the Blue Carbon Capacity of Belizean Mangroves with Ecological, Economic, and Policy Perspectives
(2015-04-24)In recent years, mangrove forests have experienced increasing deforestation rates in Belize due to coastal development. Our client, the Belize Ministry of Forestry, Fisheries, and Sustainable Development, wants to determine ... -
A spark for collective action: Challenges and opportunities for self-governance in temporary fisher-designed Fish Refuges in Mexico
(2020)Despite decades of study, the question of how to achieve sustainable small-scale fisheries is unresolved. Because small-scale fishing is diverse and hard to control, one management approach places fishers at the center of ... -
Abiotic modulators of Podocnemis unifilis (Testudines: Podocnemididae) abundances in the Peruvian Amazon
(2011-06)Previous studies have demonstrated that river-based surveys can provide an inexpensive source of information for neotropical zoologists, yet little information is available to inform the application of this technique for ... -
Assessing Vertebrate Abundance and the Effects of Anthropogenic Disturbance on Tropical Forest Dynamics
(2012-04-27)The Madre de Dios river basin in southeastern Peru is one of the largest and most diverse forest ecosystems on the planet. Though conservation zones with strict protection do exist in the basin, human population growth ... -
Assessment of Sea Turtle Rehabilitation in North Carolina
(2019-04-26)As is the case with all sea turtle species, the five species that occur within North Carolina waters are listed as either threatened or endangered under the Endangered Species Act of 1973. Due to their endangered/threatened ... -
A Multiscale Investigation of Snake Habitat Relationships and Snake Conservation in Illinois
(2008-02-11)Snake populations in the North American tallgrass prairie appear to be declining, yet data unavailability impedes the development of enhanced ecological understanding of snake species-habitat relationships and also hinders ... -
Broad Scale Conservation: Protected Areas and Species Interactions
(2009)This dissertation consists of four chapters. The first three chapters examine protected areas (or parks) from multiple perspectives. Parks are the first, and often only, line of defense in efforts to conserve biodiversity. ... -
Citizen-Based Sea Turtle Conservation Across the Developing-Developed World Divide
(2011)This dissertation research explores participatory sea turtle conservation monitoring through a comparison of two case studies, one in North Carolina (NC), USA and the other in Baja California Sur (BCS), Mexico. Participatory ... -
Conserving California’s Klamath-Cascade Using Spatial Climate Projections
(2014-12-08)Global climate change complicates long-term conservation of forests. To be effective into the future, conservation efforts need to consider potential global change impacts and the ability of plants and animals to adapt. ... -
Conserving Moving Species under Changing Landscapes and Climates
(2008-08-04)To conserve biodiversity, it is critical to understand the dynamic landscapes and climates through which species move and how the environment influences movement choices. In particular, I am interested in how species respond ... -
Crop Insurance and Climate Change: Balancing structure and flexibility to improve on-farm management of climate risk
(2014-04-18)EXECUTIVE SUMMARY: INTRODUCTION Crop insurance has become an important tool for managing economic and environmental risk in the agricultural sector, and one of the largest sources of Federal subsidies to agricultural producers. ... -
Deforestation risks posed by oil palm expansion in the Peruvian Amazon
(Environmental Research Letters, 2018-11-01)Further expansion of agriculture in the tropics is likely to accelerate the loss of biodiversity. One crop of concern to conservation is African oil palm (Elaeis guineensis). We examined recent deforestation associated with ... -

Effects of National Development and Conservation Strategies on Rural Livelihoods Around Makokou, Gabon
(2017-04-28)Balancing development and conservation is a struggle that all countries face, but is especially difficult in tropical, developing nations. Development activities in these nations often rely on extractive industries to diversify ... -
Estimating the population size of lemurs based on their mutualistic food trees
(Journal of Biogeography, 2018-11-01)Aim: Species’ distributions and abundances are primarily determined by the suitability of environmental conditions, including climate and interactions with sympatric species, but also increasingly by human activities. Modelling ... -
Evaluation of Tiger Conservation in India: the use of comparative effectiveness research
(2010-04-25)Tigers, the largest of the felids, are now a globally threatened species with only approximately 3000 wild tigers surviving. India contains about 60% or 2000 of the animals, yet despite aggressive conservation efforts the ... -
