Many species of Neotropical snakes, especially boids, are known to prey on bats, although documentation is relatively uncommon. Epicrates cenchria have been observed foraging for bats in elevated vegetation or inside caves. Here, we report a predation event by E. cenchria on an emballonurid bat, Peropteryx kappleri, at 0915 h on 3 January 2019, dur...

Here we describe three cixiid species new to science which we assign to the hitherto monotypic genus Ferricixius Hoch & Ferreira, 2012 from Brazil. Ferricixius michaeli sp. nov. and F. goliathi sp. nov. of the new species are—like the type species Ferricixius davidi Hoch &Ferreira, 2012—obligately cavernicolous and display varying degrees of troglo...

Cross-habitat spillover may be the outcome of a process of habitat loss or degradation where the receiving habitat serves as a refuge for organisms. Once surface habitats are lost or degraded, animals can find underground refuge in caves. This paper is focused on testing whether taxonomic order richness inside caves is positively affected by the lo...

A história da Biologia Subterrânea no Brasil é recente quando comparada a outros países, em especial os da Europa e da América do Norte. Neste capítulo, apresentamos os primeiros estudos da fauna cavernícola brasileira, os pesquisadores pioneiros e a implantação dos primeiros centros de pesquisa no país. Além disso, apresentamos a evolução da legis...

Community stability and carrying capacity are essential core concepts in ecology because they reflect the interactions between organisms and their environment and provide clues to predictability. Since caves are considered stable habitats, we used long-term invertebrate monitoring to understand temporal and spatial carrying capacity in a neotropica...

Albinism is a genetic disorder that causes pigmentation anomalies. Even though supposedly rare in free-living mammals, cases of albinism have been reported worldwide, particularly in bats. In this article we present a new case of albinism in a Lionycteris spurrelli Thomas, 1913. The individual, observed in an Amazon region iron ore cave, in Norther...

Understanding the factors underpinning species abundance patterns in space and time is essential to implement effective cave conservation actions. Yet, the methods employed to monitor cave biodiversity still lack standardization, and no quantitative assessment has yet tried to optimize the amount and type of information required to efficiently iden...

Albinism is a type of deficient in melanin production could be the result of genetic anomalies that are manifest as the absence of coloration of part or the entire body of an organism. This type of chromatic disorder can affect several vertebrate species, but is rarely found in nature. Among bats, more than 450 cases of total or partial loss of bod...

The stability of temperature and humidity in caves is well known. However, little is known if higher or lower cave environmental stability (temperature, humidity, light and others) implies changes in the structure of the biological communities. Number, position and size of entrances, then size, depth, host rock and extent of the cave, the amount an...

Due to their high economic value, karstic areas and caves have been affected for decades in Brazil. Accordingly, such systems have been receiving the attention of managers, environmental agencies and researchers, especially in recent years. The present study collected information regarding the cave invertebrate fauna of the Northwest region of Mina...

Herein are recorded the composition and richness of 188 specimens of social wasps collected processing pig carcasses (Sus scrofa L.) in a Brazilian Savannah. Among the species collected Polybia (Myrapetra) fastidiosuscula de Saussure, 1854 (n = 178), Polybia (Trichotorax) ignobilis (Haliday, 1836) (n = 6), Apoica (Apoica) gelida Van der Vecth, 1972...

292-297, 30 de setembro de 2012 292 SimõeS et al. ABSTRACT. An inventory of social wasps in Cerrado biome of the southern of the state of Minas Gerais was performed. A comparison between field and Riparian Forest areas was made in relation to species richness; correlations between diversity, sample methods and environmental factors were conducted....

The genus Ornithodoros is worldwide distributed and features 113 known species. However, some species are rare and collections are scarce. The present paper expands the known distribution of two species of soft ticks, O. rondoniensis and O. marinkellei, by about 1400 km to the east, in caves in two municipal districts in the state of Pará, northern...

Inadequate land use and the overexploitation of natural resources are causing serious impacts on cave environments and therefore the proposal of conservation actions become necessary. The objective of the present study was to gather information on the invertebrate fauna of seven caves in the region of Arinos, in the northwest of Minas Gerais state,...

Social wasps (Hymenoptera, Vespidae, Polistinae) usually build nests using vegetable materials mixed with water and salivary secretion, resulting in a product similar to paper. Between April 2009 and March 2010 an inventory of these wasps was made at Unilavras/Boqueirão Biological Reserve, located in the municipality of Ingaí-MG. Thirty four specie...

Abstrat Siparuna apiosyce (Mart. ex Tul.) A.DC. is a small tree found in the interior of the riparian forest. Its amphistomatic leaves have the paracytic type of stomatic complexes and are covered by a thin and smooth cuticle, with trichomes throughout its length. The mesophyll is formed by a layer of palisade parenchyma and some layers of spongy p...
