Species Richness and Ecological Diversity of Myxomycetes and Myxomycete-Like Organisms in the Tropical Forests of Brazil
… territory and besides harboring some of the most biodiverse ecosystems on the planet, this vast area also houses about 83% of the Brazilian population. Approximately 175 million people live in urban and rural areas with fragments of coverage of these biomes which contributes to the loss of …

Past Environmental Change On The Eastern Andean Flank, Ecuador
… Ecuador (EAF) contains some of the world’s most biodiverse ecosystems. Andean montane forests are threatened due to anthropogenic pressures and both current and projected climate change. This thesis examines the palaeoecological history of two stratigraphic sequences (Mera Tigre West [MTW] and …

A reassessment of the conservation status of a rare Florida endemic mint, Macbridea alba
Plants are foundational to the planet’s biodiverse ecosystems and despite their critical role in successful conservation and restoration efforts, plants lack adequate protection. At least 40% of all vascular plants on Earth face increased global risk of extinction. Effective conservation is often …

Coral reef soundscapes : spatiotemporal variability and links to species assemblages
Coral reefs are biodiverse ecosystems that are at risk of degradation as a result of environmental changes. Reefs are constantly in a state of flux: the resident species assemblages vary considerably in space and time. However, the drivers of this variability are poorly understood. Tracking these …

The effects of warming on carbon and microbial community wetland dynamics at Turnbull National Wildlife Refuge, Washington
<p>Wetlands are biodiverse ecosystems that play a key role in the biogeochemical cycling of carbon. In the face of global warming, wetland hydroperiods could shift causing changes in their functionality. My field experiment surveyed 3 plots within 12 wetlands of each hydroperiod class (i.e. 12 …

Climate variability and extremes in the Okavango River Basin, southern Africa
… Africa is a region of highly sensitive and biodiverse ecosystems. It spans Angola, Namibia and Botswana, with the world-famous Okavango Delta located in the latter country. The ecosystems depend on the highly seasonal ORB streamflow, which is also the major source of freshwater for the rural …

Fire Ecology of Northern Andean grasslands: Estimating recent fire history and its impact on páramo plants
… grasslands of the Northern Andes are highly biodiverse ecosystems that provide ecosystem services for the millions of people that live in the region (Buytaert et al., 2011; Ramsay, 2014). These fragile alpine ecosystems are vulnerable to the impacts of global environmental change and land use …
