Canopy area of large trees explains aboveground biomass variations across neotropical forest landscapes. Repositório Alice
MEYER, V.; SAATCHI, S.; CLARCK, D. B.; KELLER, M.; VICENT, G.; FERRAZ, A.; ESPÍRITO-SANTO, F.; OLIVEIRA, M. V. N. d'; KAKI, D.; CHAVE, J..
Large tropical trees store significant amounts of carbon in woody components and their distribution plays an important role in forest carbon stocks and dynamics. Here, we explore the Properties of a new lidar-derived index, the large tree canopy area (LCA) defined as the area occupied by canopy above a reference height. We hypothesize that this simple measure of forest structure representing the crown area of large canopy trees could consistently explain the landscape variations in forest volume and aboveground biomass (AGB) across a range of climate and edaphic conditions. To test this hypothesis, we assembled a unique dataset of high-resolution airborne light detection and ranging (lidar) and ground inventory data in nine undisturbed old-growth...

Diversity and structure of social wasps community (Hymenoptera: Vespidae, Polistinae) in neotropical dry forest. Repositório Alice
ELISEI, T.; VALADARES, E.; ALBUQUERQUE, F. A. de; MARTINS, C. F..
Social wasps are potential predators of agricultural pest species. The objective of this study was to conduct a survey of the community of social wasps (Polistinae species) that inhabit the neotropical dry forest named Caatinga of Paraiba, Northeast of South America (Brazil), and to compare the richness and abundance of wasps located in areas of Caatinga with those inhabiting areas of organic intercropping farming. The present study sampled 10 Polistinae species distributed in six genera. Two new species were registered for the state. The comparison between the community of social wasps of the Caatinga showed that there was not statistical difference in the richness and abundance between the natural vegetation and organic intercropping. This means that...

Fruit dispersal syndromes in animal disseminated plants at Tinigua National Park, Colombia RChHN
LINK,ANDRÉS; STEVENSON,PABLO R.
Fruit dispersal syndromes (groups of plants with similar fruit morphology, presumably adapted to dispersal by a particular set of vectors) have been described in a variety of tropical localities. In some cases the presence of different syndromes in each locality suggests independent evolution of fruit traits in response to selective pressures imposed by the particular animal community in each place. However, it is still unclear how general are fruit syndromes, and this is important to understand the evolution of mutualistic relationships. We compiled morphological information from about 500 fleshy fruited species at a lowland Neotropical forest in Tinigua National Park, Colombia, in an effort to test for the existence of fruit dispersal syndromes. We found...
