Network analysis as a tool for ecological interactions studies has been widely used since last decade. However, there are few on the factors that shape network patterns in communities. In this sense, we compared topological properties of interaction between flower-visiting social wasps and plants two distinct phytophysiognomies Brazilian savanna (Riparian Forest Rocky Grassland). Results showed landscapes differed species richness composition, also networks had different patterns. The was...

The forest fragmentation is caused by natural or anthropic actions, which affect negatively the biota and environmental services rendered biological diversity. However, there little information on reflex of these actions in many different groups animals, such as social wasps, are abundant significantly present neotropical environments, causing a major impact communities they live due to their role food webs. As enemies, wasps important control agricultural plagues; environment, nectar...

Conservation Units are an important tool for the Brazilian biota protection. However, various taxa, including social wasps, undersampled or unknown in these areas. Therefore, our study aimed to assess wasp richness and distribution Minas Gerais state, southeastern Brazil. The wasps were sampled between 2015 2019 Ritápolis National Forest (FLONA Ritápolis), Alto-Montana Private Natural Heritage Reserve (RPPN Alto-Montana), Rio Machado Basin State Environmental Protection Area (APA Machado)...

Several studies have shown that habitat complexity is an important factor for the dynamic and stability of interacting species. However, it not known how may affect tolerance wasp-flower interactions to local extinction. Based on this perspective, in study, we aimed compare wasp flower visiting guild extinction two different types vegetation (Riparian Forest Rocky Grassland). Through observations made during one year, verified structure plant-wasp interaction network differed between areas,...

O desmatamento imposto por culturas agrícolas afeta negativamente as interações ecológicas protagonizadas determinadas espécies, como vespas sociais. Uma hipótese é que o tamanho dos fragmentos florestais e sua proximidade destas podem influenciar na nidificação das sociais área de plantio. Objetivou-se, portanto, testar esta hipótese. trabalho ocorreu em Inconfidentes Ouro Fino, Minas Gerais, Brasil. método utilizado foi a busca ativa, percorrendo os mata áreas associadas um período 32...

The Parque Estadual da Serra do Papagaio is the largest area of natural preservation in south Minas Gerais, with areas Floresta Atlantica, de Araucaria and Campos Altitude. Although this an biological importance, there are many groups that have not yet been studied there: for example social wasps, which insects belonging to order Hymenoptera, family Vespidae, play important ecological role different ecosystems. This study was carried out aforementioned at altitudes between 1600 2200 m 20...

Despite the important role of order Odonata in ecosystems, there is a lack information about dragonfly communities several regions, high elevation sites, and environmentally protected areas Minas Gerais State, Brazil. Our objective was to assess abundance richness damselfly along an elevational gradient Atlantic Forest,southeastern This study conducted Fernão Dias Environmental Protection Area,Mantiqueira Mountain region, Gonçalves, sites covered by Seasonal Semideciduous mixed forests....

Os opiliões desempenham diferentes serviços ambientais, no entanto há poucas informações quanto a riqueza e distribuição dessas populações em ecossistemas, mesmo Unidades de Conservação (UC), como estado Minas Gerais, sudeste do Brasil. A partir disso, o objetivo presente estudo visa analisar diversidade opiliofauna duas inseridas ecossistemas distintos Gerais. O Trabalho foi conduzido na Área Proteção Ambiental Rio Machado (APA), domínio Mata Atlântica, Parque Nacional das Sempre Vivas...

Ecosystem fragmentation negatively affects biological diversity and compromises different environmental services. This situation occurs in two important biomes Brazil, the Atlantic Forest Cerrado. There is little information on effects of animal taxa, including social wasps. It was hypothesized that fragments are small size subject to anthropogenic pressures have reduced wasp richness colony numbers. study aimed investigate effect forest Polistinae number at Cerrado sites southern central...

As vespas sociais nidificam em diferentes espécies de plantas, no entanto, as informações relação à possível preferência por determinados tipos substratos vegetais são escassos ecossistemas brasileiros. Nesse panorama o presente estudo tem objet ivo obter sobre nidificação desses insetos áreas Floresta Decidual. O trabalho fo i realizado estado Minas Gerais, Brasil, período junho 2014 a abril 2015. Foram registradas 128 colônias 19 distribuídas 12 gêneros nidificadas 30 famílias vegetais. se...

The state of Minas Gerais has high biodiversity, characterized by strong ecosystem heterogeneity that favors richness social wasps. There are currently 109 species known to occur in the state, however, there is lack information concerning distribution these insects among different ecosystems. objective this study was evaluate wasp and distributions ecosystem, thereby generating data for use discerning relevant priority environments vespid conservation Gerais. We evaluated articles, theses,...

Mischocyttarus saussurei nests show a curious architectural pattern which could be related to colony camouflage. Since information on that species is scarce in literature, this study aimed record ecological data M. saussurei, as well morphometric its nests. Data was collected at the Parque Estadual do Ibitipoca state park and municipalities of Barroso Inconfidentes, Minas Gerais state, Southeastern Brazil. Seven colonies were located, exclusively conserved environments. Five dissected for...

Various studies have described changes in richness and abundance of insect groups along altitudinal gradients, but there is little information about social wasps (Hymenoptera, Vespidae) this regard. This study evaluated the influence altitude on diversity these insects fragments semideciduous forest a tropical climate. Three different elevations southern Minas Gerais, from 997 to 2080 meters, were studied. Sampling was carried out 24 days ten-month period by active collection. A total 34...

Existem poucos estudos de inventários opiliões (Arachnida) em muitos ecossistemas e estados brasileiros. Nesse sentido, o objetivo do presente estudo foi inventariar a fauna Floresta Estacional no sul Minas Gerais. O conduzido 14 municípios estado Gerais, fragmentos floresta estacional semidecidual, período março 2017 abril 2019. Foram registradas 34 morfoespécies, incluindo quatro morfoespécies inéditas para ciência, Tricommatinae sp.1, Anoplogynus sp.1 sp.2 Liogonyleptoides sp.1. A...

Social insects use different strategies to defend their colonies, including camouflage. In order expand knowledge, regarding the strategy of camouflage in social wasps, information is presented on pattern species: Parachartergus smithii (De Saussure), wagneri Du Buysson, Chartergellus communis Richards, Metapolybia cingulata (Fabricius) and Mischocyttarus anthracinus Richards.These species are uncommon inventory studies Brazil.

There are different methodologies used to make an inventory of social wasps. In general, these methods divided into active search and passive collections. Each method has a performance, depending on the environment in which collection is being carried out. Thus, choice for proper methodology according study area will impact success sampled species.
