Microbial Diversity In A Venezuelan Orthoquartzite Cave Is Dominated By The Chloroflexi (Class Ktedonobacterales) And Thaumarchaeota Group I.1c, Hazel A. Barton, Juan G. Giarrizzo, Paula Suarez

The majority of caves are formed within limestone rock and hence our understanding of cave microbiology comes from carbonate-buffered systems. In this paper, we describe the microbial diversity of Roraima Sur Cave (RSC), an orthoquartzite (SiO4) cave within Roraima Tepui, Venezuela. The cave contains a high level of microbial activity when compared with other cave systems, as determined by an ATP-based luminescence assay and cell counting. Molecular phylogenetic analysis of microbial diversity within the cave demonstrates the dominance of Actinomycetales and Alphaproteobacteria in endolithic bacterial communities close to the entrance, while communities from deeper in the cave are dominated (82–84%) …

Four new species of Desmoxytes are described from southern China: D. lingulata sp. n., D. parvula sp. n., and D. nodulosa sp. n., from Guangxi Zhuang Autonomous Region, and D. getuhensis sp. n. from Guizhou Province. In addition, new records of D. scutigeroides Golovatch, Geoffroy & Mauriès, 2010 and D. scolopendroides Golovatch, Geoffroy & Mauriès, 2010 are provided, with a modified key to Desmoxytes species currently known to occur in China. Two of the new species, D. nodulosa sp. n. and D. getuhensis sp. n., seem to be troglobites.

A new species of Harmonicon F. O. Pickard-Cambridge, 1896 (Araneae, Dipluridae) is described, from a medium-sized lateritic cave in Parauapebas, Pará, Brazil. The male holotype and only specimen known of H. cerberussp. n. was found near the entrance of Pequiá cave. This taxon is the fourth species described and the southernmost record for the genus. The new species displays some troglomorphic characteristics, such as reduction and merging of the posterior median and both pairs of lateral eyes and pale yellow to light brown coloration. Both characters are diagnostic when compared to the normal separated eyes and reddish to dark brown …

The aim of this study was to evaluate the rock surface temperature (RST) regime in Kateřinská Cave in the Moravian Karst (Czech Republic, South Moravia) using nondestructive infrared methods. Air temperature monitoring was also included to quantify the dominant factors affecting the RST. Measurements were taken during the period covering January, 2010 to March, 2012. HOBO air temperature sensors with data loggers were placed in front of the cave entrance, in the entrance corridor and on selected sites in the cave interior. An infrared (IR) thermometer was used to measure the surface temperature of the solid rock. The RST in …
