We present new records of four open-habitat birds in the southern Espinhaço Range, state of Minas Gerais, also known as the Quadrilátero Ferrífero. Three of these species (Micropygia schomburgkii, Veniliornis mixtus and Coryphaspiza melanotis) are inedit occurrences for the region and two are globally threatened (C. melanotis and Culicivora caudacuta), what draws attention for the preservation of native open-habitats within the Quadrilátero Ferrífero region.

Protected areas are designed to maintain environmental conditions that favor the occurrence of a wide variety of taxa. However, few studies have devoted attention to inventories of biota in these areas. In this study, we provide a checklist of cladocerans for the poorly studied Sempre Vivas National Park, Minas Gerais state. Samples were collected in lotic and lentic environments, with a total of 27 species being recorded and the highest contribution coming from the Chydoridae family (21 spp.). Minas Gerais state is widely studied in relation to cladoceran fauna; nevertheless, the results indicate three new records. The genus Monospilus was reported for the first time in the Neotropical region.

The distribution of Anthus nattereri, an endangered species, is extended at least 170 km to the north of the nearest locality in southeastern Brazil. New records of five individuals are provided from the municipality of Itabirito, within the Quadrilátero Ferrífero region, Minas Gerais state. Anthus nattereri was photographed and tape-recorded, sometimes in sympatry with Anthus hellmayri, a species it closely resembles. Records were made mostly on burnt open grasslands (“campos limpos”) making the conservation of this species a difficult task.

Forest Remnants

The Black Hawk-Eagle Spizaetus tyrannus (Wied, 1820) is a typical forest raptor classified as an endangered species in the state of Minas Gerais, southeast Brazil. Threats include deforestation and fragmentation of forest areas. Although the present investigation points 16 new records of the species in the Quadrilátero Ferrífero, it is noteworthy that the advance of mining activity and expansion of forestry of Eucalyptus spp. in this region are subtracting the forest remnants and increasingly reducing available habitats for this predator inside its limits.

Microhabitat Heterogeneity

The Espinhaço Range is a vast chain of mountains comprising ca. 120,000 km2 in the central portions of Minas Gerais and Bahia states, eastern Brazil (Ribeiro et al. 2014). Although this range represents less than 1.5% of the Brazilian territory, it harbors ca. 10% of Brazil’s angiosperm flora (Ribeiro et al. 2012). Furthermore, estimates suggest that ca. 30% of the Espinhaço Range flora is endemic (Giulietti et al. 1987). This high percentage of diversity and endemism may relate to the microhabitat heterogeneity in the “campos rupestres”, a savanna-like vegetation associated with quartzite and ironstone outcrops and white sand patches, at elevations above 900 m (Conceição & Pirani 2005, Ribeiro et al. 2014). The Diamantina Plateau, a quartzite formation of the Espinhaço Range in Minas Gerais, extends from the Araçuaí Basin, in the high Jequitinhonha Basin, to the Rio das Velhas Basin (Ribeiro et al. 2014). The Serra do Cabral, another part of the Espinhaço Range, is a rectangular mountain plateau in the same state in the São Francisco Basin, located to the west of the Diamantina Plateau and separated from it by a valley ca. 40 km wide (Hatschbach et al. 2006).

We present new records of Phibalura flavirostris for the state of Minas Gerais, a little known and endangered species in the state, including notes on feeding and breeding behavior. We also present a review of records of the species in this state based on specimens housed in ornithological collections. It was noted the consumption of fruits belonging to five different plant families and reproductive evidence in a new state locality. The species proved to be rare in Minas Gerais, being relatively common in a few localities. P. flavirostris proved to be resident in the Quadrilátero Ferrífero region and were not found evidence of altitudinal migration. However the available records are inconsistent to affirm about the migration patterns of this species. The preservation of certain areas and new studies on the natural history are important for the conservation of the species in Minas Gerais state.

After the examination of a large collection of Oniscidea from caves in the Brazilian states of Bahia, Minas Gerais, Pará, Sergipe and São Paulo, 12 species were recognized in the families Philosciidae and Scleropactidae. Four new species are described: Alboscia jotajota sp. nov. from the Açungui group; Androdeloscia akuanduba sp. nov. and Amazoniscus spica sp. nov. from the Carajás Formation; and Metaprosekia igatuensis sp. nov. from the Quadrilátero Ferrífero karst region. In addition, Atlantoscia inflata, Benthana longicornis, B. olfersii, B. picta and Paratlantoscia rubromarginata (Philosciidae) are recorded from Brazilian caves for the first time; and Benthana iporangensis, B. taeniata and Circoniscus bezzii (Scleropactidae) have the knowledge of their distribution extended to cave habitats.

RESUMO A mineração de ouro é uma das principais fontes de contaminação de arsênio (As) no Quadrilátero Ferrífero em Minas Gerais. O As é um elemento tóxico capaz de causar sérios danos à saúde humana. Com o objetivo de investigar formas mais ecológicas e igualmente eficientes para a remoção de As em solos, empregou-se a técnica de lavagem de solos (soil washing) com uso de extratos com biossurfactantes (BS) visando promover a mobilização do As contido em solo de mina de ouro abandonada. Para a produção dos extratos, foram selecionadas duas culturas mistas de bactérias produtoras de BS (MPCB e MPBR) tolerantes a alta concentração de arsênio (8 mg.L-1). Os tensoativos produzidos foram estáveis em ampla faixa de pH, 3-11; temperatura, 28-50ºC e salinidade, 1-5% NaCl (p.v-1). Nos testes de lavagem de solo, em pH 11, as remoções de As obtidas com os extratos MPCB (14,01 e 13,72%) e MPBR (12,04 e 12,31%) foram superiores àquelas obtidas com soluções a 1% (p.v-1) dos surfactantes comerciais SDS (0,87 e 0,71%); saponina (0,57 e 0,55%) e lecitina de soja (2,05 e 2,63%). Os resultados dos testes em coluna foram igualmente influenciados pelo pH e pela proporção sólido:líquido. As maiores remoções de As: 25,43% (MPCB) 22,43% (MPBR) foram obtidas em pH 11, na proporção 1:40 (g.mL-1), após 10 ciclos de extração. Os extratos MPCB e MPBR removeram o As solúvel em água, os íons ligados ao carbonato e aqueles adsorvidos. Ambos os extratos tiveram comportamento semelhante ao ácido etilenodiaminotetracético (EDTA) e ao extrato de cultura microbiana comercial (GorduraKlin®).

Habenaria longissima, a new species from the H. nuda species complex, is described and illustrated. It is remarkable for the exceptionally long lateral segments of the petals and labellum, which are the longest among Neotropical Habenaria, both in absolute and inproportional terms. Despite the morphological similarity, Bayesian and parsimony phylogenetic analyses based on nuclear (ITS) and plastid DNA markers (matK), revealed that H. longissima is distantly related to other species of the complex, and constitutes an independent lineage. Its distribution is unusual in that it is the only species of Orchidaceae restricted to the Quadrilátero Ferrífero in the State of Minas Gerais and to Chapada Diamantina, in the central part of the Espinhaço range in the State of Bahia, with the populations 1000 km from each other. Habenaria longissima is a rare species, known only from three localities and four populations and informally proposed as Endangered due to the small area of occupancy and small number of known populations.
