Within the context of global carbon cycles, knowledge of phytoplankton community structure is essential for understanding and predicting the transport of carbon from surface waters to the deep ocean. From a combination of flow cytometric analyses and image-enhanced microscopy, t…
The dominant habitat-type of Omo National Park (ONP), Ethiopia, is grassland. This grassland supports a variety of wild herbivores and indigenous people; the latter hunt large herbivores for subsistence or graze their domestic livestock in the Park. Therefore, an understanding o…
Grazing by domestic livestock is one of the primary ways by which humans have modified landscapes. At low stocking rates livestock grazing can modify vegetation community composition, but at high stocking rates grazing can also reduce vegetation productivity and initiate soil er…
Tropical coral reefs are among the most diverse ecosystems of the world but facing increasing threats to their health. Over the last thirty years, many Caribbean coral reefs have undergone dramatic changes and experienced large losses in coral cover, due to direct and indirect a…
Within the Great Basin of the Western United States, management discussions regarding the impacts of grazing by livestock and feral horses on Greater Sage-grouse (\textit{Centrocercus urophasianus}, hereafter sage-grouse) often focus on the negative impacts to habitat, and specu…
The California floristic province is home to a rich diversity of plant species, and the ecosystems they compose have a long and complex history of human management and anthropogenic disturbance. This is especially true of native grassland habitats, which have been burned, grazed…
Arid ecosystems worldwide are experiencing losses in ecosystem function and services due to human impacts and accelerated climate change. In Colorado Plateau grassland systems, historic grazing practices combined with an arid and variable climate may have caused an irreversible …
