The interaction between droughts and land-use fires threaten the carbon stocks, climate regulatory functions, biodiversity of Amazon forests, particularly in southeast, where deforestation ignitions are high. Repeated, severe, or combined result tropical forest degradation via nonlinear dynamics may lead to an alternate vegetation state. Here, we discuss major insights from longest (more than 10 years) largest (150-hectare) experimental burn forests. Despite initial resistance low-intensity...
Despite the historical efforts to list and organize taxonomic knowledge about Brazilian ant fauna, most diverse in world, several gaps regarding species distribution data sampling coverage persist. In an attempt fill some of these gaps, we here apply a scientometric approach provide updated overview ants Brazil based on formal publications diversity territory. last 50 years, studies revealed 1130 species, corresponding around 70% known occur country. The biomes with highest number described...
Abstract Tropical studies traditionally describe insect diversity variation throughout the year. The temporally structured responses of assemblages to climate seasonality vary across ecosystems due gradients resource availability and limiting ecological factors. These idiosyncratic might be particularly true vast geographical range Brazilian territory, including various environments that harbor one most diverse ant faunas worldwide. This study addressed relationship between climatic...
Community of ants that nest in dead twigs on the ground Central Amazonian forest, Brazil.A total area 2,880 m 2 four forest sites, near Manaus, Brazil, was searched for ant colonies nesting ground.An amount 3,706 (0.5-5 cm diameter) were gathered, which only 623 (16.8%) had ants, is equivalent to a density 0.22 nests per .Seventy species have been found.The predominant genera Pheidole (Westwood), Crematogaster (Lund), and Solenopsis (Westwood).For most species, many found workers brood,...
Leaf-cutter ants ( Atta spp.) remove leaf litter and woody debris—potential fuels—in around their nests foraging trails. We conducted single three annual experimental fires to determine the effects of this leaf-cutter ant activity on behavior low-intensity, slow-moving fires. In a transitional forest, where southern Amazon forest meets Brazilian savanna, we tested whether trails (i) inhibit fire spread due lack fuels, (ii), thereby, reduce total burned area during these low-intensity fires,...
Research findings in natural sciences need to be comparable and reproducible effectively improve our understanding of ecological behavioural patterns. In this sense, knowledge frontiers biodiversity studies are directly tied taxonomic research, especially species-rich tropical regions. Here we analysed the information available 470 on Brazilian ant diversity published last 50 years. We aimed quantify proportion that provide enough data validate identification, explore frequency properly...
The Bromeliaceae family exhibits several adaptations that allow the occurrence of its members in different physiognomies, including Caatinga. arrangement leaves rosette forms a cistern or tank, which nutrient-rich water accumulates. This provides microhabitat for reproduction, feeding, and larval development many invertebrates. aim this study was to survey bromeliad-associated invertebrate fauna test hypothesis seasonal changes community composition. We conducted two surveys rainy (February,...
Abstract: This study examined whether high nutrient concentrations associated with leaf-cutting ant nests influence plant growth and water relations in Amazon rain forests. Three of Atta cephalotes were selected along 31 Amaioua guianensis Protium sp. trees that grouped into near distant (>10 m) from nests. A 15 N leaf-labelling experiment confirmed located accessed nutrients Trees exhibited higher relative rates (based on stem diameter increases) average compared further away; however...
Este estudo investigou o papel das saúvas na recuperação da vegetação pós-fogo. Foi hipotetizado que a perturbação do fogo aumenta abundância de ninhos saúva (1) e as atividades remoção sementes (2) desfolha (3), especialmente no ambiente borda. Os foram inventariados mapeados após 17 meses, checados para registro sua atividade novas colônias emergindo área. Realizou-se experimentos comparativos plântulas em duas parcelas 50 ha, uma submetida anual (tratamento) outra sem (controle). A foi...
This study aims to analyze how the vegetation structure (physiognomy) and seasonal changes between seasons (wet dry) influence richness, diversity composition of ant species arboreal shrubby Caatinga environments. The was significantly different among three strata for all parameters (mean diameter vegetation, level herbaceous cover, degree coverage thickness litter percentage canopy cover). We collected 127 species. mean number approximately two times higher in rainy season than dry season....
This study evaluates the richness and composition of epigeic ant fauna in two Caatinga areas (site 1: Brejo Novo 2: Frizuba) within a transitional region (between Decidual Atlantic Forest) Municipality Jequié, state Bahia, Brazil. Ants were sampled using pitfall traps Winkler extractor method 50 randomly chosen points, totalizing sampling area 12.5 ha per site. Overall, we identified 60 species belongingto 27 genera. The most speciose genera Pheidole, Camponotus, Solenopsis (with five each)...

In order to understand the effects of human impacts on structure and functioning tropical forests, we should consider studies animal-plant interactions such as antplant mutualistic interactions.We investigated between ants (Azteca genera) Cecropia plants in habitats secondary forest pasture used cattle fields. We tested for following hyphothesis: (i) from are more susceptible foliar herbivory than forest, (ii) defense promoted by Azteca genus is less efficient when compared forested areas....
Natural earth mounds in many ecosystems harbor higher biodiversity than surroundings because they provide greater habitat heterogeniety. However, the semi-arid Caatinga ecosystem of NE Brazil, natural have much less vegetation and leaf litter with lower as compared to surrounding lowlands. The following hypotheses were tested: (i) low cover on results from highly compacted leached soils adjacent lowlands (ii) reduce ant populations diversity limited foraging nesting resources. This study was...
