Abstract: Anthropogenic disturbance often results in the proliferation of native species particular groups that leads to biotic homogenization. Leaf-cutting ants are an example such winner organisms tropical rain forests, but their response dry forests is poorly known. We investigated Atta colony density areas forest Brazil with different distance roads and vegetation cover. colonies were surveyed 59 belt transects 300 × 20 m, covering a total area 35.4 ha. found 224 colonies, 131 which...
Abstract Anthropogenic disturbance and climate change are the main drivers of biodiversity loss ecological services around globe. There is concern that will exacerbate impacts thereby promote biotic homogenization, but its consequences for unknown. We investigated individual interactive effects increasing chronic anthropogenic ( CAD ) aridity on seed dispersal provided by ants in Caatinga vegetation north‐eastern Brazil. The study was conducted Catimbau National Park, Pernambuco, Within an...
SUMMARY Habitat loss is widely recognized as the major cause of global biodiversity decline, but remaining habitat increasingly threatened by chronic human disturbances. Using a multi-model averaging approach we examined association between five disturbance surrogates and richness taxonomic functional composition ants in Brazilian Caatinga. pitfall traps 47 plots near Parnamirim city (Pernambuco) across two soil types (sand clay), recorded 53 species from 27 genera. Ant on sand was slightly...
Abstract Habitat fragmentation studies have produced complex results that are challenging to synthesize. Inconsistencies among may result from variation in the choice of landscape metrics and response variables, which is often compounded by a lack key statistical or methodological information. Collating primary datasets on biodiversity responses consistent flexible database permits simple data retrieval for subsequent analyses. We present relational links such field taxonomic nomenclature,...
Abstract Understanding the processes that allow phylogenetically related plant species coexist is important to understand ecological and evolutionary structure biological communities. In this study, we investigated how Erythroxylum simonis , pauferrense citrifolium share niche dimensions according abiotic characteristics of their environments occurrence. To end, in ten pre-established plots an Atlantic Forest remnant northeastern Brazil, carried out a population survey three characterised by...
Abstract The taxonomic diversity (TD) of tropical flora and fauna tends to increase during secondary succession. This may be accompanied by changes in functional (FD), although the relationship between TD FD is not well understood. To explore this relationship, we examined correlations ants forest age forests at α‐ β‐diversity levels using single‐ multi‐trait‐based approaches. Our objectives were understand ant patterns evaluate role conservation biodiversity resilience forests. Ant...
Abstract Anthropogenic disturbances are known to modify plant–animal interactions such as those involving the leaf‐cutting ants, most voracious and proliferating herbivore across human‐modified landscapes in Neotropics. Here, we evaluate effect of chronic anthropogenic disturbance ( e.g ., firewood collection, livestock grazing) vegetation seasonality on foraging area, foliage availability leaf consumption herbivory rate ant Atta opaciceps semiarid Caatinga, a mosaic dry forest scrub...
Abstract Leaf‐cutting ants ( LCA ) are polyphagous and dominant herbivores throughout the N eotropics that carefully select plant individuals or parts to feed their symbiotic fungus. Although many species‐specific leaf traits have been identified as criteria for choice of food plants, factors driving intraspecific herbivory patterns in less well studied. Herein, we evaluate whether not drought‐stressed native plants a preferred source using free‐living colonies two leaf‐cutting ants, A tta...
Abstract The release from bottom‐up control is a key process promoting the proliferation of leaf‐cutting ants (LCA) along neotropical rainforest edges. Considering preference LCA for drought‐stressed plants, edge‐induced drought‐stress in plants could be one mechanisms behind this response. We hypothesized that growing forest edge suffer higher levels drought stress, which makes them more suitable food resource and affects colony density Brazilian Atlantic remnant. Additionally, we...
Abstract Ecosystem engineer species can affect the assembly and maintenance of biological communities by altering local environmental conditions. Several palm tree play this role in changing surrounding environment mainly through fall entire rachis formation a thick homogeneous leaf litter layer beneath canopy. However, their impact on soil animal remains unclear. In particular, organisms (e.g. ants) be negatively affected palm‐driven changes, since they are especially susceptible to...
Resumo As espécies engenheiras do ecossistema podem afetar a constituição e manutenção das comunidades biológicas, alterando as condições ambientais locais. Várias de palmeiras desempenham este papel na mudança ambiente circundante, principalmente através da queda raques inteiras formação uma camada folhas espessa homogênea sob o dossel. Entretanto, seu impacto sobre animais solo permanece pouco claro. Em particular, os organismos (por exemplo formigas) ser afetados negativamente por...
