“…We used binomial error distribution in both models, with a "quasi" correction for overdispersion for the arthropods model. Finally, we classified sampled ants (both from epigaeic and arboreal strata) as predatory or non-predatory (according to Baccaro et al, 2015 and with help of a taxonomist; Julio M.C. Chaul), and used only predatory ants for analyses.…”

Reduced predation by arthropods and higher herbivory in burned Amazonian forests

Biodiversity losses have increased in tropical forests due to fire-related disturbances.As landscape fragmentation and climate change increase, fires will become more frequent and widespread across tropical rain forests worldwide, with important implications for forest dynamics by altering plant-animal interactions. Here we tested the hypothesis that recurrent fires in tropical rain forests change bottom-up and topdown forces controlling the abundance of insect herbivores, which in turn increases herbivory. To quantify herbivory, we collected 50 leaves per tree of five species in burned and unburned experimental plots (N = 75) in southeastern Amazonian forests.We measured leaf nitrogen content and leaf thickness of tree leaves as bottom-up factors that could explain differences in herbivory; we measured predation pressure on model caterpillars and estimated the abundance of predatory ants as top-down factors. We found higher herbivory in burned than in unburned forests, as well as lower predator attacks in caterpillar models and lower abundance of predatory ants.Leaf nitrogen content did not vary across treatments. Birds attacked model caterpillars more frequently in burned than in unburned forests, and leaf thickness was higher in burned forests, but these factors together were not enough to offset the higher herbivory in burned plots. Fire degrades tropical forests not only by killing trees and altering their structure and community dynamics, but also by reducing predatory arthropods and disrupting predator-prey interactions, which triggers increased herbivory. These indirect impacts of recurrent fires probably contribute to further alter forest structure, functioning, and to decrease regeneration in Amazonian forests.

“…The richness distribution between genera and subfamilies in APA Pandeiros follows the proportion expected for these groups of ants in Brazil, with Camponotus, Pheidole and Solenopsis belonging to the subfamilies Formicinae and Myrmicinae, as the most recurrent (Baccaro et al, 2015). Despite efforts to identify challenging genera, these three still dominate the list of morphospecies in our checklist.…”

“…In addition, we highlight the species E. edentatum, from the subfamily Ectatomminae, also widely distributed in Brazil (see Baccaro et al, 2015;Delabie et al, 2015), as the most common species in studies carried out at APA Pandeiros. This species has reasonably deep nests in the ground, with trash disposal that favors better seed germination (Delabie et al, 2007).…”

“…The new distribution records revealed in APA Pandeiros belong to Camponotus, Pheidole and Strumigenys. These genera are highly diverse and taxonomically challenging, with many described (over 800 species) and undescribed species (Baccaro et al, 2015). In this sense, our checklist helps to fill gaps in species distribution.…”

Habitat transformation and species loss bring enormous environmental damage, whereas establishing protected areas promotes more sustainable use of environmental resources through biodiversity conservation. In this study, we aimed to point out gaps in ant knowledge and provide a species checklist that contributes to biodiversity conservation in the transition areas between Cerrado and Caatinga biomes, constantly threatened by land use changes. This checklist integrates data from previous studies developed at “Área de Proteção Ambiental do Rio Pandeiros” (APA Pandeiros), Minas Gerais, Brazil, involving ant diversity and their contribution to ecological processes accessed and described in the studies. We showed and discussed how authors managed and provided information regarding methodologies and habitats sampled. We listed 143 ant species formally named. Pheidole, Camponotus and Cephalotes were the most speciose genera, with more than ten species each. Among ants involved in ecological processes, 40 are linked to diaspore removal (part of seed dispersal) and 30 to carcass interaction (part of the decomposition process). Unbaited pitfall traps, epigeic stratum and Cerrado sensu stricto, were the top sampling method, stratum, and habitats among ant studies. We presented proposals for the best management and integration of data from surveys in APA Pandeiros (e.g., sharing the results of the studies with the APA managers, creating a database, and the local community). These surveys are fundamental for understanding biodiversity and ecological processes and provide valuable information to conservation biology. Therefore, neglecting the importance of the Cerrado-Caatinga transition can lead to irreparable setbacks for scientific knowledge and biodiversity.
