A new species of land crab, Sesarma Say, 1817 (Decapoda, Brachyura), from the Pleistocene of Jamaica Naturalis
Collins, J.S.H.; Mitchell, S.F.; Donovan, S.K..
Terrestrial arthropods are poorly known from the Cenozoic of Jamaica. A probably Late Pleistocene land crab, Sesarma primigenium sp. nov., is described from the Western Cement Company Cave, parish of St. Elizabeth, southwestern Jamaica. The same species is also tentatively recognised from the Late Pleistocene Red Hills Road Cave, parish of St. Andrew, eastern central Jamaica. The propodi of the new species are moderately globose, with an upper margin that is comparatively short and finely granulate ridged; the fingers are obscurely spooned and gaped; and the in-turned fixed finger is in line with, and a litt le shorter than, the basal margin. Of the nine extant endemic members of this subgenus in Jamaica, S. jarvisi Rathbun and S. verleyi Rathbun have...

Analysis of bacterial communities and characterization of antimicrobial strains from cave microbiota BJM
Yasir,Muhammad.
Abstract In this study for the first-time microbial communities in the caves located in the mountain range of Hindu Kush were evaluated. The samples were analyzed using culture-independent (16S rRNA gene amplicon sequencing) and culture-dependent methods. The amplicon sequencing results revealed a broad taxonomic diversity, including 21 phyla and 20 candidate phyla. Proteobacteria were dominant in both caves, followed by Bacteroidetes, Actinobacteria, Firmicutes, Verrucomicrobia, Planctomycetes, and the archaeal phylum Euryarchaeota. Representative operational taxonomic units from Koat Maqbari Ghaar and Smasse-Rawo Ghaar were grouped into 235 and 445 different genera, respectively. Comparative analysis of the cultured bacterial isolates revealed distinct...

Chromosomal characterization of Pseudonannolene strinatii (Spirostreptida, Pseudonannolenidae) Iheringia, Sér. Zool.
Campos,Kleber Agari; Fontanetti,Carmem S..
The chromosomes of the cave millipede Pseudonannolene strinatii Mauriès, 1974 were investigated. The diploid chromosome number was found to be 2n=16, XX/XY; the C-banding technique revealed a large amount of heterochromatin while the silver staining technique (Ag-NOR) evidenced the presence of heteromorphism of the NORs in some cells.

Epigean and subterranean ichthyofauna in Cordisburgo karst area, eastern Brazil Biota Neotropica
Trajano,Eleonora; Secutti,Sandro; Mattox,George Mendes Taliaferro.
After an ichthyofaunistic survey conducted in May 2007 on surface (epigean) water bodies of Cordisburgo karst area, State of Minas Gerais, 13 species were recorded, mostly characiforms; in addition three non-troglomorphic (normally eyed and pigmented) and one troglomorphic catfish (siluriforms) species were recorded in two caves surveyed at different occasions, totaling 17 fish species for the area. All the nominal species herein reported for Cordisburgo area have been previously reported for the Rio das Velhas basin. None of the species observed in caves were found in epigean habitats and vice-versa. The four cave species are distributed throughout subterranean stream reaches, with individuals at different size/age classes. This, associated to the lack of...

Mechanisms of pigmentation loss in subterranean fishes Neotropical Ichthyology
Felice,Vanessa; Visconti,Maria Aparecida; Trajano,Eleonora.
Troglobitic (exclusively subterranean) organisms usually present, among their apomorphies related to the subterranean life (troglomorphisms), the regression of eyes and melanic pigmentation. The degree of regression varies among species, from a slight reduction to the complete loss of eyes and dark pigmentation, without a taxonomic correlation. While mechanisms of eye reduction have been intensively investigated in some troglobites such as the Mexican blind tetra characins, genus Astyanax, and the European salamander, Proteus anguinus, few studies have focused on pigmentation. The Brazilian subterranean ichthyofauna distinguishes not only by the species richness (23 troglobitic fishes so far known) but also by the variation in the degree of reduction of...

Natural and human impacts on invertebrate communities in Brazilian caves BJB
FERREIRA,R. L.; HORTA,L. C. S..
Species richness, abundance, distribution and similairity between cave invertebrate communities were compared among seven caves located in the Peruaçu River valley, north of Minas Gerais State, Brazil. Such comparisons aimed to determinate the degree of biological complexity in the sampled caves, calculated by the "Index of Biological Complexity in Caves", presented in this manuscript. The presence of potencial or real impacts on the cave fauna was also investigated. A total of 1,468 individuals belonging to 57 families of: Acarina, Pseudoscorpionida, Araneida, Opilionida, Amblypygi, Isopoda, Geophilomorpha, Scutigeromorpha, Spirostreptida, Coleoptera, Collembola, Diptera, Dictyoptera, Ephemeroptera, Ensifera, Heteroptera, Hymenoptera, Lepidoptera,...

Natural history and population data of fishes in caves of the Serra do Ramalho karst area, Middle São Francisco basin, northeastern Brazil Biota Neotropica
Trajano,Eleonora; Secutti,Sandro; Bichuette,Maria Elina.
During the exploration and mapping of new caves in Serra do Ramalho karst area, southern Bahia state, cavers from the Grupo Bambuí de Pesquisas Espeleológicas - GBPE (Belo Horizonte) noticed the presence of troglomorphic catfishes (species with reduced eyes and/or melanic pigmentation), which we intensively investigated with regards to their ecology and behavior since 2005. Non-troglomorphic fishes regularly found in the studied caves were included in this investigation. We present here data on the natural history of two troglobitic (exclusively subterranean troglomorphic species) fishes - Rhamdia enfurnada Bichuette & Trajano, 2005 (Heptapteridae; Gruna do Enfurnado) and Trichomycterus undescribed species (Trichomycteridae; Lapa dos Peixes and...

Galati,Eunice A. B.; Nunes,Vânia L. B.; Boggiani,Paulo Cesar; Dorval,Maria Elizabeth C.; Cristaldo,Geucira; Rocha,Hilda C. da; Oshiro,Elisa T.; Gonçalves-de-Andrade,Rute M.; Naufel,Guelisa.
The present paper deals with the phlebotomine species captured during the period from January 1998 to June 2000 in 12 caves located in the Serra da Bodoquena, situated in the south central region of Mato Grosso do Sul State, Brazil. Three of the caves are situated further north (in Bodoquena county), seven in the central area (Bonito county) and two in the south (Jardim county). These last two caves and three of those in Bonito are located at the west side of the ridge. Eighteen species of phlebotomines were captured within the caves: Brumptomyia avellari (Costa Lima, 1932), Brumptomyia brumpti (Larrousse, 1920), Brumptomyia cunhai (Mangabeira, 1942), Brumptomyia galindoi (Fairchild & Hertig, 1947), Evandromyia corumbaensis (Galati, Nunes, Oshiro...

Phlebotomines (Diptera, Psychodidae) in the Speleological Province of the Ribeira Valley: 2. Parque Estadual do Alto Ribeira (PETAR), São Paulo State, Brazil Rev. Bras. entomol.
Galati,Eunice A. B.; Marassá,Ana Maria; Gonçalves-Andrade,Rute Maria; Consales,Cleide Aschenbrenner; Bueno,Edna Fátima Maria.
The Parque Estadual do Alto Ribeira (PETAR) with about 250 caves, in an Atlantic forest reserve, is an important ecotourist attraction in the Ribeira Valley, an endemic area of American cutaneous leishmaniasis (ACL). With the purpose of investigating Leishmania vector species bothersome to humans the sandfly fauna was identified and some of its ecological aspects in the Santana nucleus, captures were undertaken monthly with automatic light traps in 11 ecotopes, including caves, forests, a camping site and domiciliary environments, and on black and white Shannon traps, from January/2001 to December/2002. A total of 2,449 sandflies representing 21 species were captured. The highest values of abundance obtained in the captures with automatic light traps were...

Pleistovultur nevesi gen. et sp. nov. (Aves: Vulturidae) and the diversity of condors and vultures in the South American Pleistocene Ameghiniana
Alvarenga,Herculano; Brito,Guilherme R.R.; Migotto,Rafael; Hubbe,Alex; Höflibg,Elizabeth.
Pleistovultur nevesi, a new genus and species of a large Vulturidae is described from the Upper Pleistocene or beginning of the Holocene, based on a complete and well preserved right tibiotarsus from the Cuvieri cave deposits, one of the hundreds of caves of the Lagoa Santa region in Minas Gerais state, Brazil. Also described here is a distal half of a left tibiotarsus from Gruta dos Brejões, a cave in Morro do Chapéu, Bahia state, Brazil, which probably belongs to another not-yet-known genus and species of the Vulturidae. The described material, added to prior literature, is proof of the appreciable diversity of the Vulturidae during the Pleistocene in South America.

Surface and subterranean ichthyofauna in the Serra do Ramalho karst area, northeastern Brazil, with updated lists of Brazilian troglobitic and troglophilic fishes Biota Neotropica
Mattox,George Mendes Taliaferro; Bichuette,Maria Elina; Secutti,Sandro; Trajano,Eleonora.
After an ichthyofaunistic survey in several epigean (surface) water bodies of the Serra do Ramalho, southern Bahia, conducted in May 2007, 44 species were recorded; in addition, three non-troglomorphic (normally eyed and pigmented) and two troglomorphic species were recorded only in caves, totaling 49 species of fishes for the area, which represents a little more than one fourth of the total registered in the literature for the entire Rio São Francisco basin. In these caves, which have been studied since 2005, eight non-troglomorphic species were sampled and their presence in both epigean and subterranean habitats, associated to the lack of morphological differences, indicate that they may be either troglophiles (species encompassing individuals able to...
