Ecohydrology of a seasonal cloud forest in Dhofar
The hydrology of a semiarid broadleaf forest in Dhofar (Oman) is investigated by performing a field experiment and a modeling study. Based on the results of the field experiment, the ecosystem in Dhofar is classified, for the first time, as a seasonal deciduous cloud forest. Owing to the seasonal …

Moths fight back: arms race in the cloud forest
Moths and bats engage in a coevolutionary arm race, where the same signals bats use to find moths are being used by moths to avoid bats. Moths evolve not only behavioral but acoustic responses to avoid predation by bats. This research examines one small component of a complex, multispecies arm race …

Assessing conservation status of remnant mammal populations in a Neotropical cloud forest
Neotropical cloud forests are some of the most biodiverse and yet threatened ecosystems. Terrestrial mammals play key roles delivering numerous ecosystem services within such systems including seed dispersal and nutrient cycling. Yet like the habitat in which they reside, some mammal species are …

Avifauna and Anthropogenic Forest Disturbance in Two Biodiversity Hotspots.
… thesis is to examine the impact of anthropogenic forest disturbance on avifaunal communities in two biodiversity hotspots- lowland tropical forest in the Lambusango Forest Reserve within the Wallacean archipelago and Neotropical cloud forest in Cusuco National Park, Mesoamerica. Both these study …

Changing Human Impact On The Montane Forests Of The Eastern Andean Flank, Ecuador
The montane cloud forests of South America are some of the most biodiverse habitats in the world, whilst also being especially vulnerable to climate change and human disturbance. Today much of this landscape has been transformed into a mosaic of secondary forest and agricultural fields. This thesis …

VERTEBRATE COMMUNITY CHANGES ACROSS A 3200M AMAZON-TO-ANDES GRADIENT: COMPOSITION, STRUCTURE, AND OCCUPANCY
… transects composed of tropical montane cloud forest. In 2016, we replicated and extended the survey along one transect, setting 80 cameras from 3578 to 519 m a.s.l. We use these findings in conjunction with existing range hypotheses to assess (1) if there are major distribution changes …

Greater Galagos near Mt. Kasigau, Kenya: Population Density Estimates
… Kasigau has a unique regional microclimate, a cloud forest, which provides many different flora and fauna a home. To examine population density, two different methods were used. The first method was using line transects and analyzing results using Distance 6.0. These surveys were conducted …

Mortality of native forest vegetation in the Kaimai ranges
… 40 years and affects a wide range of species and forest types. The mortality occurs above 550 m altitude and on each prominence has a lower limit which corresponds closely with the predominant cloud zone in each area. The severity of the damage ranges from complete mortality of canopy species to a …

From Plot to Region: Assessing the Role of Land Use in Tropical Montane Forest Structure and Dynamics
Forest disturbance and land use are strong drivers of forest structure, composition, and dynamics and yet, their role in shaping tropical montane landscapes is poorly understood. The overarching goal of my dissertation is to broaden our understanding on the role of land use in shaping forest …
