Data from: The roles of geography and environment in divergence within and between two closely related plant species inhabiting an island-like habitat

Aim: In island-like habitats, geographic isolation facilitates population and species divergence by constraining gene flow, while environmental isolation can enhance divergence. We tested the relative contribution of geographic and environmental isolation in genetic and phenotypic divergence within and between two species of the figwort Ameroglossum (Scrophulariaceae) inhabiting spatially isolated habitats, known as inselbergs. Location: Borborema Plateau, north-eastern Brazil. Methods: Multivariate models of redundancy (RDAs) and partial redundancy analyses (pRDAs) were used to partition the geographic...

Data from: Anthropogenic disturbance of tropical forests threatens pollination services to açaí palm in the Amazon river delta

The açaí palm Euterpe oleracea Mart. in the Amazon river delta has seen rapid expansion to meet increased demand for its fruit. This has been achieved by transforming lowland forest habitats (floodplains) into simplified agroforests and intensive plantation in upland areas. As açaí palm makes an important contribution to the economy and food security of local communities, identifying management approaches that support biodiversity and ecosystem processes that underpin fruit production on açaí farms is essential....

Data from: Soil-mediated filtering organizes tree assemblages in regenerating tropical forests

Bruno Ximenes Pinho, Felipe Pimentel Lopes De Melo, Víctor Arroyo-Rodríguez, Simon Pierce, Madelon Lohbeck & Marcelo Tabarelli
1.Secondary forests are increasingly dominant in human-modified tropical landscapes, but the drivers of forest recovery remain poorly understood. Soil conditions influence plant community composition, and are expected to change over a gradient of succession. However, the role of soil conditions as an environmental filter driving community assembly during forest succession has rarely been explicitly assessed. 2.We evaluated the role of stand basal area and soil conditions on community assembly and its consequences for community functional...

Data from: Genetic differentiation associated with host plants and geography among six widespread species of South American Blepharoneura fruit flies (Tephritidae)

Kristina Ottens, Isaac S. Winkler, Matthew L. Lewis, Sonja J. Scheffer, Gessica A. Gomes-Costa, Marty A. Condon & Andrew A. Forbes
Tropical herbivorous insects are astonishingly diverse and many are highly host-specific. Much evidence suggests that herbivorous insect diversity is a function of host-plant diversity; yet, the diversity of some lineages exceeds the diversity of plants. Although most species of herbivorous fruit flies in the Neotropical genus Blepharoneura are strongly host-specific (they deposit their eggs in a single host plant species and flower sex), some species are collected from multiple hosts or flowers and these may...

Data from: The financial needs vs. the realities of in situ conservation: an analysis of federal funding for protected areas in Brazil’s Caatinga

Ana Paula Carneiro De Oliveira & Enrico Bernard
In situ conservation is an effective strategy to protect biodiversity, and Brazil has one of the largest protected area (PA) systems in the world. However, the distribution of Brazilian PAs is uneven and the Caatinga drylands are poorly protected. As financial resources are essential for effectively managing PAs, we analyzed the Brazilian Government's budget allocated to 20 federal PAs in the Caatinga between 2008 and 2014, which ranged from 231,575 USD in 2008 to 13.5...

Data from: A theoretical approach to the size-complexity rule

André Amado, Carlos Batista & Paulo R. A. Campos
The so-called size-complexity rule claims the existence of a positive correlation between organism size and number of cell types. In this spirit, here we address the relationship between organism size and number of potential tasks that can be performed. The modeling relies on the assumption that the states of the cells within the aggregates are such that the maximum fitness is realized, but also relies on the existence of tradeoffs among the distinct functions. For...

Data from: Taxonomic and functional ant diversity along a secondary successional gradient in a tropical forest

Maya Rocha-Ortega, Xavier Arnan, José Domingos Ribeiro-Neto, Inara R. Leal, Mario E. Favila & Miguel Martínez-Ramos
The taxonomic diversity (TD) of tropical flora and fauna tends to increase during secondary succession. This increase may be accompanied by changes in functional diversity (FD), although the relationship between TD and FD is not well understood. To explore this relationship, we examined the correlations between the TD and FD of ants and forest age in secondary forests at the α- and β-diversity levels using single- and multi-trait-based approaches. Our objectives were to understand ant...

Data from: Habitat disturbance selects against both small and large species across varying climates

Heloise Gibb, Nathan J. Sanders, Robert R. Dunn, Xavier Arnan, Heraldo L. Vasconcellos, David A. Donoso, Alan N. Andersen, Rogerio R. Silva, Tom R. Bishop, Crisanto Gomez, Blair F. Grossman, Kalsum M. Yusah, Sarah H. Luke, Renata Pacheco, Jessica Pearce-Duvet, Javier Retana, Melanie Tista, Catherine L. Parr & H. L. Vasconcelos
Global extinction drivers, including habitat disturbance and climate change, are thought to affect larger species more than smaller species. However, it is unclear if such drivers interact to affect assemblage body size distributions. We asked how these two key global change drivers differentially affect the interspecific size distributions of ants, one of the most abundant and ubiquitous animal groups on earth. We also asked whether there is evidence of synergistic interactions and whether effects are...
