Data from: Tree seedling responses to leaf-cutting ants herbivory in Atlantic Forest restoration sites
<p>Leaf-cutting ants (LCA) are generalist herbivores capable of causing severe plant damage. Negative impacts of ant herbivory vary according to the density of nests and availability of palatable plants; however, it is not yet clear how these herbivores affect tropical forest restoration sites. To investigate how LCA preference affects plant species performance, we evaluated the herbivory of Atta sexdens rubropilosa on native tree species seedlings in Atlantic Forest restoration sites. We expected pioneer species to suffer higher herbivory by LCA when compared with non-pioneer species, and that species with higher damage will have poorer growth and higher mortality. The experiment was conducted in three restoration sites in northern Paraná state, southern Brazil, with 1500 seedlings of 5 pioneer and 5 non-pioneer species. Sites share similar age, stand size, tree species composition, and LCA nest density. The number of attacks, degree of leaf damage, number of leaves, plant height and survival were recorded. Specific leaf area, leaf polyphenols, flavonoids, tannins, and nitrogen content were analyzed for each species. Plant damage was similar between pioneer and non-pioneer plant species. This could be explained by trait variability among species in each group and by LCA generalist foraging. Preferred species suffered decreases in growth and survival. Less preferred species suffered fewer ant attacks and no change in performance. Results suggest that ant herbivory can influence plant species establishment and thus species composition in restoration sites by reducing performance and increasing mortality of some, but not all species, making LCA an important ecological filter.</p>

Diversity, species coexistence, and functional composition patterns in subtropical Atlantic Forests invaded by non-native trees
<ol> <li>Biological invasions are a major environmental challenge today. Interactions between invasive and native species can significantly shape community structures, influencing co-existence, diversity, and functional composition of species. The subtropical Atlantic forest in southern Brazil, a recognized biodiversity hotspot, provides a unique setting to study these interactions, given its vulnerability to alien tree invasions. </li> <li>Our study sought to elucidate the impacts of such invasions on this fragile ecosystem by addressing key questions: 1) How are tree community diversity patterns affected by the abundance of invading alien tree species? 2) What are the patterns of coexistence between native and alien invasive trees? 3) Is the functional composition of the forests altered by the abundance of invasive trees?</li> <li>To address these questions, we compiled data on the abundance and functional traits of native and invasive trees. We determined the diversity patterns and functional composition of plots with different degrees of invasion. These data were analyzed using Generalized Linear Mixed Models, Principal Component Analysis, and a coexistence index.</li> <li>In plots with a higher abundance of invasive trees, there was a significant decrease in the taxonomic and functional richness of native species. Furthermore, we observed that invasive alien trees coexisted with native species, and as the abundance of invasive trees increased, the native community weighted mean (CWM) of the leaf area and specific leaf area decreased.</li> <li>In conclusion, within the subtropical Atlantic forest areas of southern Brazil, our findings highlight that the abundance of invasive trees adversely affects the taxonomic and functional richness of native species. Furthermore, while invasive alien trees were found to coexist with native species, increased invasive abundance corresponded to a reduction in the leaf area and the specific leaf area of the native community.</li> </ol>
[SUPPLEMENTARY FILES] DIVERSITY PATTERNS AND KNOWLEDGE GAPS OF ATLANTIC FOREST EPIPHYLLOUS BRYOPHYTES: A HIGHLY NEGLECTED GROUP
<p>Epiphyllous bryophytes are a group of plants with complex adaptations to colonize the leaves of vascular plants and are considered one of the most specialized and sensitive plants groups to environmental changes. Despite their specificity and ecological importance, these plants represent a largely neglected group in scientific research and ecological data. This limited information directly affects the understanding of diversity patterns and compromises the conservation of this group in fragmented ecossystems, such as the Atlantic Forest. </p><p> </p><p> </p>
