    <p>Study regions: Chamela Cuixmala Biosphere Reserve in Mexico (A), Unidad de Producción Socialista Agropecuaria Piñero in Venezuela (B), and Mata Seca State Park in Brazil (C). Sampling sites representing different successional stages are: pastures (from P1 to P3), early (from E1 to E3), intermediate (from I1 to I3) and late stage (from L1 to L3). Seasons: rainy season (triangles) and dry season (circles). Error bars represent the ±95% confidence intervals.</p

    Summary of the tests evaluating seasonal variation at the assemblage level.

    <p>Study sites are the same as described in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0084572#pone-0084572-g001" target="_blank">Fig. 1</a>. For tests based on randomizations (composition and abundance) the standardized effect size is provided (Z = (Observed value – Expected value)/StDev of expected values). The Z-score quantifies, in units of standard deviation, the position of the observed metric within the simulated distribution. Significant relationships (p-value ≤0.05) appear in bold and marginally significant relationships (0.05). Structure: result of the Kolmogorov-Smirnov test evaluating seasonal changes in bat assemblages regarding their structure (species rank distribution). Detailed information about these analyses are presented in the method section.</p

    Percentage of variation in the population, ensemble and assemblage-level parameters associated with the variation of the explanatory variable.

    <p>Study sites are the same as described in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0084572#pone-0084572-g001" target="_blank">Fig. 1</a>. Seasons: rainy season (RS), and dry season (DS). Parameters at population-level: capture rate (individuals/night) as an indicator of local abundance of the species. Parameters at ensemble-level: capture rate (individuals/night) as an indicator of local abundance of the guild. Parameters at assemblage-level: scores of the first and second ordination axis reflecting assemblages’ dissimilarities in species composition (Species SC<sub>1</sub> and Species SC<sub>2</sub>, respectively); scores of the second ordination axis reflecting assemblages’ dissimilarities in guild composition (Guild SC<sub>2</sub>), and species richness estimated by using the first-order jackknife estimator (Jack1). Explanatory variables: successional stage (S<sub>stage</sub>) and scores of the first ordination axis reflecting sampling sites’ dissimilarities in vegetation structural complexity (V<sub>struct</sub>). n: number of sampling sites. <i>R<sup>2</sup><sub>dev</sub></i> is the fraction of the total deviance explained by a model considering all explanatory variables when the Poisson error distribution was used and <i>R<sup>2</sup></i> when the normal error distribution was used. Significant relationships according to the randomization test appear in bold. Negative relationships are shown in parentheses. Only the parameters that were significantly associated with some explanatory variable are shown in this table.

    Above-ground biomass of Neotropical secondary forests database

    No full text
    This database is the product of the 2ndFOR collaborative research network on secondary forests. The database contains aboveground biomass data (in Mg/ha) for 1334 secondary forest plots differing in time since abandonment. The plots belong to different chonosequence studies in the Neotropics. For a description of the database, see Poorter et al. 2016. Biomass resilience of Neotropical secondary forests. Nature doi:10.1038/nature16512
