Resumo. No presente estudo realizou-se um levantamento de ninhos de abelhas Meliponini na Estação Ecológica de Água Limpa (EEAL), no município de Cataguases, Minas Gerais. Foram encontrados 21 ninhos pertencentes a nove espécies: Friesella schrottkyi (Friese), Melipona bicolor Lepeletier, Plebeia sp. 1, Plebeia sp. 2, Tetragona clavipes (Fabricius), Tetragona quadrangula (Fabricius), Tetragonisca angustula (Latreille), Trigona hyalinata (Lepeletier), Trigona spinipes (Fabricius). Vinte dos 21 ninhos foram encontrados em substrato arbóreo. A fauna de Meliponini observada na EEAL é representada por um baixo número de espécies. Embora a vegetação local tenha potencial para oferecer substratos para nidificação e recursos florais, a baixa riqueza de espécies pode estar relacionada com o fato da EEAL ser um remanescente florestal isolado. Stingless Bees of the Estação Ecológica de Água Limpa, Cataguases-MG, Brazil Abstract. This study carried out a survey of nests of stingless bees present in the Estação Ecológica de Água Limpa (EEAL) in the municipality of Cataguases, Minas Gerais. We found twenty-one nests belonging to nine species: Friesella schrottkyi (Friese), Melipona bicolor Lepeletier, Plebeia sp. 1, Plebeia sp. 2, Tetragona clavipes (Fabricius), Tetragona quadrangula (Fabricius), Tetragonisca angustula (Latreille), Trigona hyalinata (Lepeletier), Trigona spinipes (Fabricius). Twenty of the 21 nests were found in arboreal substrate. The fauna of stingless bees observed in EEAL is represented by a low number of species. Although the local vegetation has the potential to provide substrates for nesting and floral resources, the low species richness may be related to the fact that the EEAL is an isolated forest remnant.

A urbanização tem causado a fragmentação de vários ambientes naturais, levando à perda de muitos processos ecológicos como a polinização, realizada principalmente por abelhas, em especial as espécies de Meliponini, que tem reduzido drasticamente as suas populações devido à perda de habitat pela expansão urbana. O objetivo deste estudo foi realizar um levantamento das espécies de abelhas sem ferrão em áreas urbanas do município de Ubá - MG, Brasil, relacionar a riqueza e abundância das espécies encontradas com a taxa de ocupação das variáveis estruturais da paisagem das áreas urbana e relacionar a presença das espécies obtidos com estas variáveis. Foram encontrados 28 ninhos pertencentes a quatro espécies, Tetragonisca angustula (Latreille), Trigona spinipes (Fabricius), Nannotrigona testaceicornis (Lepeletier) e Friesella schrottkyi (Friese). Não houve relação significativa entre a riqueza e abundância de Meliponini e variáveis estruturais de vegetação analisadas, possivelmente devido a valores baixos no número de ninhos e espécies encontrados. Somente T. spinipes se mostrou relacionada com a presença de vegetação. Os resultados mostram que a comunidade Meliponini é composta por espécies generalistas capazes de utilizar cavidades artificiais e plantas ornamentais como uma fonte alternativa de recursos, comuns em áreas urbanas. Os resultados obtidos neste estudo servem de alerta para atuais condições dos remanescentes vegetais em áreas urbanas na cidade de Ubá, além de também poderem ser usados como material de apoio na tomada de decisão sobre projetos de conservação e recuperação de áreas degradadas, tendo como foco sobre as abelhas e sua importância para a sustentabilidade destes ecossistemas.Where the most Adapted Remain: Stingless Bees Community (Hymenoptera: Apidae, Meliponini) in Urban Areas of the City of Uba, Minas Gerais, Brazil Abstract. The urbanization has caused the fragmentation of various natural environments, taking to loss of many ecological processes in which includes pollination, realized mainly by bees, in special Meliponini species, which has drastically reduced their populations due to loss of habitat for urban expansion. The aim of this study was to survey the species of stingless bees in urban areas of the municipality of Ubá - MG, Brazil, relate the richness and abundance of species found with the percentage of occupation of the structural variables of the urban landscape and relate the presence of the species obtained with these variables. Were found 28 nests belonging to four species, Tetragonisca angustula (Latreille), Trigona spinipes (Fabricius), Nannotrigona testaceicornis (Lepeletier) and Friesella schrottkyi (Friese). There was no significant relationship between richness and abundance of Meliponini and structural variables of vegetation, possibly due to low values in the number of nests and species obtained. Only T. spinipes showed related to the presence of vegetation. The results show that the Meliponini community is composed by generalist species able to use artificial cavities and ornamental plants as an alternative source of resources, common in urban areas. The results obtained in this study is a warning to current conditions of the plant remaining in urban areas in the city of Ubá, besides may also be used as support in taking-decision on projects for the conservation and recovery of degraded areas, focusing on bees and their importance to the sustainability of these ecosystems.

ABSTRACT The objective was to present the floristic survey of the bryophytes of the Parque Estadual da Serra do Brigadeiro. It included an evaluation of the species richness, as well as information about the substrate preference of each species and its geographic distributions in Brazil. We found 208 taxa of bryophytes: one hornwort, 88 liverworts and 119 mosses. This richness represents ca. 26% of the bryoflora of Minas Gerais State and ca. 13% of that known for Brazil. Eighteen of the bryophytes species are endemic to Brazil, whereas 19 species are recorded for the first time in Minas Gerais. The bryoflora showed preference for tree bark (30%) and rock (23%) as substrates. Our data show that the Parque Estadual da Serra do Brigadeiro is an important area for the diversity conservation of Brazilian bryophytes and maintenance of endemic species of the country.

There are few studies on Odonata communities in Brazil, even in its most deeply studied states, such as Minas Gerais. Therefore, it is proposed the presentation of results on the Odonata species richness of Parque Estadual do Ibitipoca (Ibitipoca State Park), located at the Zona da Mata region in the Minas Gerais state, Brazil. This Conservation Unit is considered a priority area for the conservation of the state’s invertebrates. The objective of this study was to know the number of species within the area. 100 hours of sampling were carried out, distributed amongst five campaigns of four consecutive days between  November 2016 and July 2017. There were recorded 20 different species, including a new record for the state and one potential new species. Species richness was low due to the sampling being focused exclusively on lotic systems, and also to the environment’s homogeneity. Despite the low number of species, Parque Estadual do Ibitipoca is relevant to the conservation of the Minas Gerais state’s Odonata.

Neomuscina Townsend includes 41 species distributed throughout the Nearctic and Neotropical Regions. Although the genus has a large number of species, it has been ignored and its taxonomy is confusing and has many flaws. In this work we analyzed the following species recorded for Brazil: Neomuscina atincta Snyder, N. atincticosta Snyder, N. capalta Snyder, N. currani Snyder, N. douradensis Lopes & Khouri, N. goianensis Lopes & Khouri, N. inflexa (Stein), N. instabilis Snyder, N. mediana Snyder, N. mimosa Lopes & Khouri, N. neosimilis Snyder, N. nigricosta Snyder, N. paramediana Lopes & Khouri, N. pictipennis pictipennis (Bigot), N. ponti Lopes & Khouri, N. sanespra Snyder, N. schadei Snyder, N. similata Snyder, N. stabilis (Stein), N. transporta Snyder, N. vitoriae Lopes & Khouri and N. zosteris (Shannon & Del Ponte). Neomuscina nigricosta and N. transporta are new distribution records for Brazil. Three new species are described: Neomuscina anajeensis sp. nov. from Anagé (Bahia), Neomuscina maculata sp. nov. from Botelhos (Minas Gerais) and Neomuscina snyderi sp. nov. from Mata de São João (Bahia). An identification key based on the morphological characters of both male and female is provided. Species distributions are discussed and updated, and the number of species now recorded for Brazil is 29.

According to its owners, the Forest of Seu Nico (FSN) from the Viçosa municipality, Minas Gerais, Brazil, never has been logged and is therefore considered a primary forest. Nevertheless, the forest patch suffered impacts due to selective wood and non-timber extraction, fragmentation and isolation. Aim of this study was to test if the FSN, despite impacts, preserved characteristics of primary forests, which are elevated percentages of non-pioneer (>90%), animal-dispersed (>80 %), understory (>50%) and endemic species (~40%). For that, all trees with diameter at breast height equal or major than 3.2 cm within a plot of 100 x 100 m were identified. With 218 tree species found within this hectare, the FSN's species richness is outstanding for the region. The percentages of non-pioneer (92 %), animal-dispersed (85 %), understory (55 %) and endemic species (39.2 %) from the FSN fulfill the criteria proposed for primary forest. Therefore, we conclude that the FSN maintained its characteristics as a primary forest which highlights its importance for the conservation of biotic resources in the region, where similar fragments are lacking or not described yet.

Abstract: The objective of this work was to analyze the spatial distribution and the behavior of species richness and diversity in a shrub savanna fragment, in 2003 and 2014, using ordinary kriging, in the state of Minas Gerais, Brazil. In both evaluation years, the measurements were performed in a fragment with 236.85 hectares, in which individual trees were measured and identified across 40 plots (1,000 m2). Species richness was determined by the total number of species in each plot, and diversity by the Shannon diversity index. For the variogram study, spatial models were fitted and selected. Then, ordinary kriging was applied and the spatial distribution of the assessed variables was described. A strong spatial dependence was observed between species richness and diversity by the Shannon diversity index (<25% spatial dependence degree). Areas of low and high species diversity and richness were found in the shrub savanna fragment. Spatial distribution behavior shows relative stability regarding the number of species and the Shannon diversity index in the evaluated years.

Latitudinal Patterns

© 2019 John Wiley & Sons Ltd Understanding the distribution of biodiversity across the Earth is one of the most challenging questions in biology. Much research has been directed at explaining the species latitudinal pattern showing that communities are richer in tropical areas; however, despite decades of research, a general consensus has not yet emerged. In addition, global biodiversity patterns are being rapidly altered by human activities. Here, we aim to describe large-scale patterns of species richness and diversity in terrestrial vertebrate scavenger (carrion-consuming) assemblages, which provide key ecosystem functions and services. We used a worldwide dataset comprising 43 sites, where vertebrate scavenger assemblages were identified using 2,485 carcasses monitored between 1991 and 2018. First, we evaluated how scavenger richness (number of species) and diversity (Shannon diversity index) varied among seasons (cold vs. warm, wet vs. dry). Then, we studied the potential effects of human impact and a set of macroecological variables related to climatic conditions on the scavenger assemblages. Vertebrate scavenger richness ranged from species-poor to species rich assemblages (4–30 species). Both scavenger richness and diversity also showed some seasonal variation. However, in general, climatic variables did not drive latitudinal patterns, as scavenger richness and diversity were not affected by temperature or rainfall. Rainfall seasonality slightly increased the number of species in the community, but its effect was weak. Instead, the human impact index included in our study was the main predictor of scavenger richness. Scavenger assemblages in highly human-impacted areas sustained the smallest number of scavenger species, suggesting human activity may be overriding other macroecological processes in shaping scavenger communities. Our results highlight the effect of human impact at a global scale. As species-rich assemblages tend to be more functional, we warn about possible reductions in ecosystem functions and the services provided by scavengers in human-dominated landscapes in the Anthropocene.
