Data from: Changes in tree and liana communities along a successional gradient in a tropical dry forest in south-eastern BrazilYule Roberta Ferreira Nunes, Mario Marcos Espirito-Santo, Giovana Rodrigues Da Luz, Maria Das Dores Magalhaes Veloso, Rubens Manuel Dos Santos, Sofia Calvo-Alvarado, Sandra Milena Duran, Santos D'Ângelo Neto, Bruno G.

We investigated changes in species composition and structure of tree and liana communities along a successional gradient in a seasonally dry tropical forest. There was a progressive increase in tree richness and all tree structural traits from early to late stages, as well as marked changes in tree species composition and dominance. This pattern is probably related to pasture management practices such as ploughing, which remove tree roots and preclude regeneration by resprouting. On the...
The nutrient demands of regrowing tropical forests are partly satisfied by nitrogen (N)-fixing legume trees, but our understanding of the abundance of those species is biased towards wet tropical regions. Here we show how the abundance of Leguminosae is affected by both recovery from disturbance and large-scale rainfall gradients through a synthesis of forest-inventory plots from a network of 42 Neotropical forest chronosequences. During the first three decades of natural forest regeneration, legume basal area...
Data from: Plant phenological asynchrony and community structure of gall-inducing insects associated with a tropical tree speciesMarcilio Fagundes, Renata C.F. Xavier, Maurício L. Faria, Laura G.O. Lopes, Pablo Cuevas-Reyes & Ronaldo Reis-Junior
The dynamics of occurrence of target-organs in plant populations produces windows of opportunity that directly and indirectly affect the structure of herbivore communities. However, mechanisms that drive herbivore specialization between resource patches are still poorly known. In the present study, we tested three hypotheses related to variation in host plant phenology and community structure (i.e. composition, richness and abundance) of gall-forming species: (i) plants with early leaf-flushing in the season will have greater vegetative growth...
Data from: Patterns of taxonomic and functional diversity of termites along a tropical elevational gradientCássio Alencar Nunes, André Vieira Quintino, Reginaldo Constantino, Daniel Negreiros, Ronaldo Reis-Júnior & G. Wilson Fernandes
Patterns of termite richness along elevation gradients may be related to different responses by termite functional groups to changes in environmental conditions. We investigated the distribution of termite species richness along an elevational gradient of cerrado and rupestrian grasslands in the Espinhaço Mountain Range, in Brazil. Fifty termite species were recorded, with the family Termitidae being dominant; 16 species are endemic to open areas of cerrado and 1 species, Cortaritermes rizzinii, is endemic and restricted...
Land-use change occurs nowhere more rapidly than in the tropics, where the imbalance between deforestation and forest regrowth has large consequences for the global carbon cycle1. However, considerable uncertainty remains about the rate of biomass recovery in secondary forests, and how these rates are influenced by climate, landscape, and prior land use2, 3, 4. Here we analyse aboveground biomass recovery during secondary succession in 45 forest sites and about 1,500 forest plots covering the major...
Clearing tropical vegetation impacts biodiversity, the provision of ecosystem services, and thus ultimately human welfare. We quantified changes in land cover from 2000 to 2015 across the Cerrado biome of northern Minas Gerais state, Brazil. We assessed the potential biophysical and social-economic drivers of the loss of Cerrado, natural regeneration and net cover change at the municipality level. Further, we evaluated correlations between these land change variables and indicators of human welfare. We detected extensive...
Variation in community structure of gall-inducing insects associated with a tropical plant supports the hypothesis of competition in stressful habitatsLetícia Fernanda Ramos, Ricardo Ribeiro De Castro Solar, Henrique Santos & Marcilio Fagundes
Environmental factors act as drivers of species coexistence or competition. Mesic environments favor the action of parasites and predators on gall communities, while the factors that determine the structure of gall communities in xeric environments remain unknown. We evaluated the structure of gall communities along an environmental gradient defined by intrinsic plant characteristics, soil fertility and aridity, and investigated the role of competition as a structuring force of gall communities in xeric environments. We created...
