Ecología en América del Sur Virtual Issue


South America Virtual Issue The continent of South America is home to an overwhelming range of ecosystems and ecological interactions, due to its north–south orientation that spans over 60 degrees of latitude, a diversity of topography from the floodplain of the Amazon to the Andean mountain chain, the longest mountain range in the world, and a resulting range of climate from the driest desert in the world, the Atacama, to the Valdivian rainforests at the southern tip of the South American peninsula.

Crab-eating foxes as an equatorial test of Bergmann´s rule, functional group diversity in the Pampas grasslands, frugivorous birds in the Atlantic Forest, fish and their parasites in the great Párana river, curiously flowering bamboo in the Gondwana-derived southern beech forests and gender-bending grasses in the mystical Patagonian steppe can all be found in this Virtual Issue on South America, a collection of papers published in the British Ecological Society journals Journal of Ecology, Journal of Animal Ecology, Journal of Applied Ecology, Functional Ecology and Methods in Ecology and Evolution. In addition to the research in relatively untouched landscapes, studies on the impact of agriculture, particularly soybean cultivation, forest fragmentation, and land-use impacts on carbon storage in semiarid ecosystems, highlight relevant issues of human impact on the landscape in the region. As all the BES journals are included here, there is a diverse array of studies and approaches, from specific focus on the plant physiology of lianas to broad-based application of macroecology theory.

When South American researchers are not working in Southern Hemisphere systems, they are comparing similar systems in the North or developing new methodologies which will be of importance for ecosystems in South America, including the value of analysis for rare species using 454 pyrosequencing and a way to organize the rich floral diversity in a functioning database. Taking an exotic journey in this Virtual Issue will give the reader an idea of the breadth of topics and insights that can only be found in the diverse continent of South America.
