The ecology of most arboreal ants remains poorly documented because of the difficulty in accessing ant nests and foragers in the forest canopy. This study documents the nesting and foraging ecology of a large (∼13 mm total length) arboreal trap-jaw ant, Odontomachus hastatus (Fabricius) (Hymenoptera: Formicidae) in a sandy plain forest on Cardoso Island, off the coast of Southeast Brazil. The r...

Forest certification has been widely adopted by Bolivian stakeholders as a result of a strong combination of policy, training, technical assistance, and economic incentives for responsible forest management. The new Forestry Law of 1996 and associated regulations, the national dependency on foreign exports, and national and international support of forest management and certification together f...

The impact of ecology and social organization on genetic structure at landscape spatial scales, where gene dynamics shape evolution as well as determine susceptibility to habitat fragmentation, is poorly understood. Attempts to assess these effects must take into account the potentially confounding effects of history. We used microsatellites to compare genetic structure in seven bat species wit...

The forest, savanna, and grassland biomes, and the transitions between them, are expected to undergo major changes in the future due to global climate change. Dynamic global vegetation models (DGVMs) are very useful for understanding vegetation dynamics under the present climate, and for predicting its changes under future conditions. However, several DGVMs display high uncertainty in predictin...

You accidentally unplug the freezer. Labour strife removes buses at rush hour. A violent storm knocks out the telephone lines. A highly disturbed ecosystem loses species to extinction. What do these events have in common? All are examples of systems in which an important connection has been severed. Just like electrical, transportation, or communication systems, the ecological systems composing...
