The impact of large terrestrial carnivores on Pleistocene ecosystems.
Large mammalian terrestrial herbivores, such as elephants, have dramatic effects on the ecosystems they inhabit and at high population densities their environmental impacts can be devastating. Pleistocene terrestrial ecosystems included a much greater diversity of megaherbivores (e.g., mammoths, mastodons, giant ground sloths) and thus a greater potential for widespread habitat degradation if p...
متن کاملEmerging Ecosystems Change the Spatial Distribution of Top Carnivores Even in Poorly Populated Areas
Humans affect biological diversity and species distribution patterns by modifying resource availability and generating novel environments where generalist species benefit and specialist species are rare. In particular, cities create local homogenization while roads fragment habitat, although both processes can increase food availability for some species that may be able to take advantage of thi...
متن کاملCarbon fluxes in ecosystems of Yellowstone National Park predicted from remote sensing data and simulation modeling
BACKGROUND A simulation model based on remote sensing data for spatial vegetation properties has been used to estimate ecosystem carbon fluxes across Yellowstone National Park (YNP). The CASA (Carnegie Ames Stanford Approach) model was applied at a regional scale to estimate seasonal and annual carbon fluxes as net primary production (NPP) and soil respiration components. Predicted net ecosyste...

Stainier* (Current Biology 20, 1840–1845; October 26, 2010) In the text and in Figure 3A of this article, we refer to chromosome 12/LG12. This is incorrect; chromosome 12 in the text and LG12 in Figure 3A should ref...
متن کاملComplexity in natural microbial ecosystems: the Guerrero Negro experience.
The goal of this project is to describe and understand the organismal composition, structure, and physiology of microbial ecosystems from hypersaline environments. One collection of such ecosystems occurs at North America's largest saltworks, the Exportadora de Sal, in Guerrero Negro, Baja California Sur. There, seawater flows through a series of evaporative basins with an increase in salinity ...
