The Espinhaço Mountain Range in Minas Gerais state in southeastern Brazil is a center of endemism of the Bromeliaceae, mainly in campo rupestre montane vegetation that grows under rigorous edapho-climatic conditions. This study sought to improve our knowledge of the Bromeliaceae from Serra da Piedade in the extreme southern portion of the Espinhaço Mountain Range where ironstone outcrops predominate. Conservation status and spatial distribution of these plants were analyzed as well as floristic similarities with other regions with rocky outcrops. Twenty-five bromeliad species were found in Serra da Piedade, with the subfamily Tillandsioideae being the best represented. Twenty-seven percent of the species were exclusive to campo rupestre environments, while 73% occurred both on outcrops and in forest habitats. The bromeliads in the study area merit special attention as two species are considered vulnerable (Racinaea aerisincola and Vriesea minarum), five are endangered, and three are critically endangered. Low Jaccard index values indicated dissimilarities between the bromeliad floras in different localities of quartzite and ironstone outcrops within the Espinhaço Mountain Range. Serra da Piedade has a distinct bromeliad flora that is threatened by mining activities and illegal harvesting and requires immediate measures to help guarantee conservation.

Microvelia joceliae Magalhães & Moreira, sp. nov. is described and illustrated based on material from Parque Natural Municipal das Andorinhas, Minas Gerais State, in southeastern Brazil. The new species can be distinguished from congeners occurring in the region by the pronotum of the apterous form covering almost the entire thorax dorsally, proepisternum with black denticles, male abdominal segments V–VII ventrally depressed, shape of the asymmetrical parameres, and female abdominal laterotergites reflected over the mediotergites and almost touching over segments V–VII.

O Parque Estadual de Ibitipoca (PEIB) está situado no sudeste do estado de Minas Gerais, entre os municípios de Santa Rita de Ibitipoca e Lima Duarte, a 21º40'-21º44'S e 43º52'-43º55'W. Apresenta em sua área um mosaico de formações vegetais, das quais o campo rupestre ocupa a maior extensão, sendo também encontradas em seus domínios diversas formações florestais. O presente trabalho teve como objetivo o levantamento das espécies de Orchidaceae ocorrentes no PEIB. Foram registrados 118 táxons distribuídos em 47 gêneros. Os gêneros mais numerosos são Pleurothallis sensu lato (13 spp.), Oncidium (12 spp. e um possível híbrido), Epidendrum (10 spp.) e Maxillaria (9 spp.). O estudo da distribuição geográfica dos táxons revelou quatro novos registros para a flora de Minas Gerais e ampliou o conhecimento sobre a distribuição de muitas espécies. Uma comparação com as espécies de orquídeas ocorrentes em outras áreas de campo rupestre conhecidas até o momento demonstra que o PEIB, embora com área relativamente pequena, é uma das regiões com maior número de espécies.

The complex vocalization of Scinax cardosoi (Anura: Hylidae), with comments on advertisement calls in the S. ruber Clade. The complex vocalization of Scinax cardosoi from a population of Minas Gerais in southeastern Brazil is described and compared with available acoustic data for the other species of the S. ruber Clade. Three distinct types of high-pitched, pulsed calls were identified, and are referred to as “short,” “long,” and “trilled” calls. Short calls (16–66 ms) resemble squeaks, and consist of a pulsed signal (8–28 pulses/call) with regular amplitude modulations throughout their duration; the amplitude peak occurs at about the midpoint of the call duration. Long calls (268–518 ms) resemble giggles, and have lower amplitude than short calls; typically, they consist of pulsed note series (1–6 notes/call). Trilled calls resemble insect chirps and have the lowest amplitude of the three call types; they consist of long (1.1–3.0 s) pulsed note series (9–25 notes/call). Acoustic data are taxonomically informative in the Scinax ruber Clade and provide phenotypic characters diagnosing S. cardosoi in addition to those features proposed in its original description. The vocalization repertoire of S. cardosoi resembles the complex vocal repertoires (i.e., multiple call types emitted in variable combinations) of members of the S. catharinae Clade more than some species of the S. ruber Clade, which tend to have simpler call structures (i.e., a single type of multipulsed note).

We located ten nests of Geotrigona subterranea in the transition area between Cerrado and Caatinga within the municipalities of Lontra and Januária, state of Minas Gerais, southeastern Brazil. We collected the nests to study their architecture in detail. In the present paper, we describe the general nest structure of this bee species in terms of: number, shape and area of the combs; size of the brood cells; size of honey and pollen pots; volume of honey and mass of pollen stored in closed pots; presence of inquiline species; and defensive characteristics. All nests were found in subterranean cavities. The nest structure of G. subterranea is similar to that of other congeneric species.

Abstract Aims: Vereda wetlands are among the most important aquatic habitats in Brazilian savannah (Cerrado) because of their association with river springs and its relevancy for biodiversity conservation. This study aimed to determine and compare the biodiversity of zooplankton in vereda lakes, differentiated by the presence or absence of aquatic macrophytes at an environmental reserve in Uberlândia, Minas Geais, Southeastern Brazil. Zooplanctonic abundance patterns and their relation with environmental parameters were also discussed and presented through multivariate statistics. Methods Twelve samples were taken at water surface, at 15-day intervals in 2006. It was observed a total richness of 75 species, including 12 genera, 29 species and one sub-species as new records for Minas Gerais State. Results Rotifers were the predominant group and Lecanidae was the most diverse family. Among cladocerans, Chydoridae showed the greatest richness and Bosminidae the highest abundance. Few adult copepods were sampled in this study, but nauplii were very frequent. Cyclopidae was the most common family among copepods and there was no record of Calanoida. Conclusions The difference in composition among the studied lakes was remarkable. The lake with macrophytes showed the greatest richness but the lowest density, and the opposite situation occurred in the other lake. This can be explained by the fact that aquatic macrophytes, as primary producers, exert a bottom-up effect on zooplankton community, sustaining a high local diversity in contrast with a low numeric abundance of these microorganisms. Therefore, this pattern may have been created by the surround heterogeneity and, at the same time, by the reduction of available minerals of the system caused by macrophyte matter fixation. Many studies on zooplankton need to be developed in palm swamp communities in order to better comprehend the biological diversity and the energy balance in different habitats for the conservation of aquatic ecosystems.

One hundred and seventy-seven individuals belonging to 120 complete or incomplete nuclear families from Bambui, in the State of Minas Gerais, southeastern Brazil, were studied in order to examine causes of variation in the eosinophil rate among subjects infested by intestinal worms with an extra-digestive cycle. Segregation analysis without correction for skewness showed that the hypothesis of the presence of an additive major gene was consistent with the data, although a dominant, recessive, or a multifactorial hypothesis could not account properly for the observed significant familial aggregation. The most parsimonious correction for skewness showed similar results, but could not distinguish between dominant and recessive models, although co-dominance was rejected. Since these models assume that skewness was attributable to the commingling of two distributions, these results seem to agree with those for uncorrected data. These findings suggest that several genetically independent factors determine the resistance/susceptibility to helminth infestation mainly through their ability to influence the eosinophil response.
