The effects of livestock and land use change on bat communities: structure, composition and changes in functional groups and ecosystem services

Research by on March 3, 2016
The overall aim of this project is to gain a better understanding of the effects of livestock and land use change on wildlife in Pantanal Wetland, Brazil. For the historically very large properties of the Pantanal, which had a range of native pasture types and low cattle densities, the continuous grazing system was economically and environmentally… Read more The effects of livestock and land use change on bat communities: structure, composition and changes in functional groups and ecosystem services

Investigating drivers of plant-soil feedback strength in tropical tree species

Research by on March 3, 2016
Tropical rainforests support the highest plant diversity in the world. Most of this diversity is comprised of exceedingly rare and seemingly similar tree species. Explaining the mechanisms allowing the coexistence of so many types of trees has therefore been a central focus of ecology for decades. An increasing body of research shows that conspecific negative… Read more Investigating drivers of plant-soil feedback strength in tropical tree species

The effectiveness of recovered riparian forests for the conservation of biodiversity and ecological processes

Research by on March 2, 2016
The overall goal of this project is to gain a better understanding of how recovered riparian forests can enhance biodiversity conservation. In tropical forests, several reforestation programs have been created to recover biological diversity in deforested environments. However, most of these studies have focused on the loss of species and ignored the loss of ecological interactions… Read more The effectiveness of recovered riparian forests for the conservation of biodiversity and ecological processes

Effects of a keystone genus on the prevalence of ectoparasites and disease in a desert rodent community

Research by on March 2, 2016
I am investigating the effects of removing kangaroo rats (Dipodomys spp.), a keystone genus, on the prevalence of ectoparasites (fleas, ticks, etc.) and pathogens (bacteria of the genus Bartonella) in a desert rodent community. This project is based at a long-term research site (established in 1977) near the town of Portal in southeastern Arizona. I collected… Read more Effects of a keystone genus on the prevalence of ectoparasites and disease in a desert rodent community

Knowledge Transfer in Northwestern Mexico: Conservation Ecology Courses to Create Local Leaders Among the Comcaac

Research by on March 2, 2016
There is widespread interest and action in the conservation of unique cultural and biological diversity. However, these actions largely lack local leadership and expertise, and learning opportunities for indigenous students are few. This is true for the Comcaac (Seri people), an indigenous culture that lived off the bounty of the desert and sea of the… Read more Knowledge Transfer in Northwestern Mexico: Conservation Ecology Courses to Create Local Leaders Among the Comcaac

Oak Regeneration Project (BIOSTRESS)

Research by on November 20, 2015
The overall goal of this project (BIOSTRESS) is to better understand the multiple phases involved in the oak regeneration process in Mediterranean environments and to provide scientific guidelines for the conservation and management of oak-dominated systems. One of the main objectives of this project is to analyse how different sources of stress (biotic and abiotic)… Read more Oak Regeneration Project (BIOSTRESS)

100 years of changes: Isotopic tracking of diet breath and trophic position of apex predators in East Africa

Research by on October 10, 2015
The aim of the project is to assess the impact of human disturbance, mainly defaunation and land-use change (agriculture and livestock), on the diet, trophic position, and movement patterns of six African carnivores. Human landscape transformation is considered to be the greatest global threat to biodiversity. In recent decades agricultural and pastoral activities in the Eastern African countries of Kenya… Read more 100 years of changes: Isotopic tracking of diet breath and trophic position of apex predators in East Africa
