Article
Despite the historical efforts to list and organize the taxonomic knowledge about the Brazilian ant fauna, the most diverse in the world, several gaps regarding species distribution data and sampling coverage persist. In an attempt to fill some of these gaps, we here apply a scientometric approach to provide an updated overview of the ants of Brazi...

Ants, an ecologically successful and numerically dominant group of animals, play key ecological roles as soil engineers, predators, nutrient recyclers, and regulators of plant growth and reproduction in most terrestrial ecosystems. Further, ants are widely used as bioindicators of the ecological impact of land use. We gathered information of ant sp...

In this study, we describe a new low‐cost technique to collect plant‐inhabiting arthropods at a height of up to 10 m without the need for specialized and complicated methods such as rope climbing or fogging. We present a model to build and apply the technique in a tropical forest understory. This technique is important because it is not only effici...

As percepções dos seres humanos expressam representações mentais sobre objetos externos com base em dados sensoriais em nível temporal, espacial, cultural, ambiental, histórico e sócio-econômico. A convivência diária de agricultores familiares tende a ampliar a percepção sobre bens e serviços ecossistêmicos prestados, bem como os impactos causados...

O objetivo neste trabalho foi estimar a erosividade e as anomalias pluviais em Belterra que é um importante município que integra o polo de grãos do oeste do Pará. Os dados de precipitação pluvial foram obtidos da Base de Dados (BDMEP) do Instituto Nacional de Meteorologia (INMET), correspondentes ao período de 1972 a 2017. Estimou-se a erosividade...

The establishment of agricultural matrices generally involves deforestation, which leads to fragmentation of the remaining forest. This fragmentation can affect forest dynamics both positively and negatively. Since most animal species are affected, certain groups can be used to measure the impact of such fragmentation. This study aimed to measure t...

Numbers of each ant species sampled at the various locations. (XLSX)
Conference Paper
Tropical forests have a high level of habitat loss, suffering an intensive process of forest fragmentation. The increasing pressure of farming and cattle ranching is one of the main causes of this problem, influencing the animal community by the environmental homogenization. To understand the impact of this homogenization on the native community st...
Conference Paper
Global warming is one of the most pressing and challenging problems that we face in this century. Although planted forests increase carbon uptake they may also have negative impacts on biodiversity. To examine this possibility, and see how native- and exotic-planted forest plantations differed, we compared ant biodiversity in teak (Tectona grandis)...
Conference Paper
Background/Question/Methods Environment impacts in the Amazon region are caused primarily by the expansion of cattle ranching and agriculture. Despite the evidence of impacts caused by deforestation, new areas are cleared of trees and new agricultural systems are introduced on a daily basis. However, studies have shown that some agroecosystems can...

The general prevalence of sexual reproduction over asexual reproduction among organisms testifies to the evolutionary benefits of recombination, such as accelerated adaptation to changing environments and elimination of deleterious mutations. Documented instances of asexual reproduction in groups otherwise dominated by sexual reproduction challenge...
Article
This study was conducted in the "restinga" (Sand Dune) of Guriri Island (18°43'S, 39° 45' W), São Mateus, Espírito Santo, Brazil. The aim of this work was to test the following hypothesis: the ant species richness in restinga is higher than in open areas and the effect of burnings on the decrease of this richness is stronger in restinga vegetation...

ABSTRAcT Palm leaf sheaths provide shelter to numerous groups of vertebrates and invertebrates, both in dry land and periodically flooded environments. Palm leaf sheaths can be considered strategic microhabitats that can be determinant of the survival of ant species inhabiting Amazon islands that undergo peri-odic flooding. In this work we studied...

Conference Paper
Slash-and-burn is the most widespread approach to preparing land for agriculture and livestock in Brazils Amazon region. Leaf-litter biomass may be totally burned in affected areas, destroying a vital habitat for thousands of invertebrate, such as ant communities. An alternative to slash-and-burn has been developed, using tractor-driven equipment t...

Nos últimos anos diversos autores têm se dedica-do ao estudo das comunidades de formigas, e dos fatores que determinam a riqueza e composição de espécies em diferentes ambientes e escalas espaci-ais. No entanto, é mais comum encontrar na literatu-ra científica estudos que se preocupam mais com padrões de riqueza de espécies de formigas do que aquel...
Article
A diversidade de espécies é afetada por vários processos que operam em diversas escalas espaciais. Em escala local, as interações biológicas e físicas são geralmente importantes para a determinação da diversidade, e neste aspecto as interações entre formigas e plantas são bastante estudadas. Este estudo teve como objetivo principal investigar a imp...

In Brazil, a large amount of knowledge is produced about the ecological interactions existing in the different biomes of the country, however, the Amazon region lacks this information, and little is known about the impact of mining activities on biotic interactions. In this sense, our proposal is to evaluate how mutualistic (pollination and dispersion) and antagonistic (herbivory) interactions are affected in post-mining restoration areas in the Amazon, using network theory tools.
