1. NET PRIMARY PRODUCTIVITY OF A MOUNTAIN FOREST ECOSYSTEM AS AFFECTED BY CLIMATE AND TOPOGRAPHY
ABSTRACT Response of terrestrial ecosystems to changing climate has become an issue of central importance for land managers and policymakers. Climate extremes and trends have a strong control on productivity of semi-arid mountain ecosystems. Located in a transition zone from continental type climate to relatively mild Black Sea type climate in Turkey, the Il

2. Monitoramento das pastagens cultivadas no cerrado goiano a partir de imagens MODIS índices de vegetação (MOD13Q1) / Monitoring cultivated pastures in the Cerrado Goiano Image from MODIS vegetation index (MOD13Q1)
Cattle ranching is extremely important for the economy of Brazil. This activity is characterized by the intensive explotation of pastures, which occupy a vast area of the Brazilian territory, i.e. approximately 150 million hectares. Currently, Brazil is the largest meat exporter in the world. Concerning its biomes, this occupation occurs mainly in the Cerrad

A pecuária é uma atividade extremamente importante para a economia do Brasil. Essa atividade se caracteriza pela exploração extensiva das pastagens, ocupando vasta área do território, aproximadamente 150 milhões de hectares. Atualmente, o Brasil é o maior exportador de carne bovina no mundo. Em relação aos biomas brasileiros, essa ocupação ocorre

4. Metabolic rate and environmental productivity: Well-provisioned animals evolved to run and idle fast
Even among vertebrate species of the same body mass and higher-level taxonomic group, metabolic rates exhibit substantial differences, for which diverse explanatory factors—such as dietary energy content, latitude, altitude, temperature, and rainfall—have been postulated. A unifying underlying factor could be food availability, in turn controlled by net

5. Global energy gradients and size in colonial organisms: Worker mass and worker number in ant colonies
Body mass shapes processes from cell metabolism to community dynamics. Little is known, however, about how the average body mass of individuals varies among ecological communities. Ants alter colony mass by independently changing worker mass and/or worker number. In a survey of 49 ecosystems from tundra to tropical rainforest, average worker mass and worker
