The role of canopy cover dynamics over a decade of changes in the understory of an Atlantic beech-oak forest
<p>This dataset hosts the main data and R codes of the analyses carried out to study the role of canopy cover dynamics over a decade of changes in the understory of an Atlantic Beech-Oak forest. We measured changes in understory taxonomical and functional composition, richness and diversity between 2006 and 2016, and relate those changes to changes in canopy coverage between both years.</p> <p>The data show changes between 2006 and 2016 in the species abundance, richness and diversity of 102 understory communities, and in the functional composition, richness and diversity for five functional traits (Leaf dry matter content, Specific leaf area, Leaf size, Plant height and Seed mass). Changes in canopy coverage between 2006 and 2016 were studied as an explanatory variable.</p> <p>The R codes show the main analyses carried out in the study: 1) The calculation of the functional composition, richness and diversity of the five traits studied (Leaf dry matter content, Specific leaf area, Leaf size, Plant height and Seed mass), 2) a Dunnett's modified Tukey-Kramer test used to test for significant relationships between four plot categories defined according to the presence or absence of canopy gaps (no gaps, gap closure, gap opening and gap persistence) and changes in the taxonomical and functional composition and diversity of the understory from 2006 to 2016. 3) An Indicator Species Analysis used to study the species that were indicators of gap opening or closure in the Atlantic Beech-Oak forest studied. 4) The calculation of the Standardized Effect Size for the functional traits of the indicator species, used to see if the species selected as gap indicators shared similar values of functional traits and had values significantly different from non-indicator species.</p>
Projected impacts of climate and land use changes on the habitat of Atlantic Forest plants in Brazil
<p>Aim:<b> </b>To provide novel evidence on the average impact of climate and land use changes on habitat suitability for tropical plants and to test previous conclusions on the relative importance of these two drivers in shaping future availability of habitat for tropical plant species.</p> <p>Location<b>: </b>Brazil's Atlantic Forest domain.</p> <p>Time period: Plant occurrences recorded between 1960 and 2014. Baseline climate from 1960-2000 and land use from 2015. Projected scenarios of climate for 2041-2060 and land use for 2050.</p> <p>Major taxa studied: Angiosperms.</p> <p>Results: Our results suggest that climate change alone will, surprisingly, have only a modest negative impact on the mean habitat suitability, decreasing it by 2% (median = -5% to -7%, variation associated with scenarios). Land use change alone had a more consistent negative impact on habitat suitability, causing mean and median reductions of 4% to 6%. When the effects of climate and land use are combined, the mean habitat suitability was reduced by 4% (median = -9% to -11%).</p> <p>Main conclusions: The combined impacts of climate and land use changes were substantial, although smaller than expected. Habitat suitability decreased for most species, but it increased substantially for some species, suggesting that the distribution of impacts across species is markedly right skewed. The impacts were typically detrimental to small-ranged species and neutral or beneficial to widespread species. Land use change rather than climate change will likely cause more losses to the habitat of Atlantic Forest plant species within the next several decades.</p>

Data from: Disentangling the factors that shape bromeliad and ant communities in the canopies of cocoa agroforestry and preserved Atlantic Forest
<p>In tropical forest canopies, host tree characteristics shape epiphyte communities, and both host tree characteristics and epiphytes determine invertebrate communities, e.g., ants. Tree height is among the factors most often mentioned as a strong predictor for both bromeliad and ant communities. However, many factors interact dynamically in shaping the tree-bromeliad-ant association. Here, we investigated the effects of the host tree and canopy structural characteristics on both bromeliads and ants. We sampled bromeliads on 180 trees and ants in 360 bromeliads living on a subset of 60 of those trees in a continuum of native forest fragments and agroforestry systems in the Atlantic Forest, a Brazilian biodiversity hotspot. We found that the host trees' crown area had a positive effect on the abundance of bromeliads. Also, the introduced tree species had higher abundance of bromeliads than native tree species. Moreover, we found that the ant species composition was different between native and introduced trees. In addition, we observed a positive effect of the size of bromeliads and tree crown height on ant species richness on both bromeliad and tree scales, but there was no effect of tree height. Taken together, our findings highlight the importance of trees with large crowns for the maintenance of bromeliads, which are also associated with richer ant communities in both Atlantic Forest and agroforestry systems. These results emphasize the importance of trees with larger crowns for biodiversity conservation in both native forest fragments and agroforestry systems.</p>
