The aim of this study was to unravel the relative role played by speleogenesis (i.e., the process in which a cave is formed), landscape-scale variables, and geophysical factors in the determination of species richness in caves. Biological inventories from 21 caves located in the southeastern Iberian Peninsula along with partial least square (PLS) regression analysis were used to assess the rela...

Originally described from limited exposures in central Noble County, Ohio, the Noble Limestone Member (Congemaugh Group, Pennsylvanian) has recently been discovered at three additional localities in northern Noble County and eastern Guernsey County. The Noble Limestone Member overlies the fresh-water Ewing Limestone Member and occurs beneath the Rock Riffle Run Limestone Member, at a position a...

Mithraea, religious Roman buildings, are very common in Italian archeological sites. There sixteen Ostia Antica (Rome, Italy)The poor state of conservation, due to the intrinsic environmental conditions, characterized them: they consist open-air museums and caves simultaneously. These places worship by presence heterogeneous materials, such as wall building materials (bricks mortars) others use...

INTRODUCTION Human activity usually leads to a deterioration in air quality; therefore, searching for places that simulate an environment without pollution is important. Artificial salt caves play crucial role, as a kind of therapy, known as halotherapy, based on treatment in a controlled air medium that simulates a natural salt cave microclimate. OBJECTIVE Evaluation of awareness about the e...

Iodine is an essential micronutrient for human health. Its deficiency causes a number of functional and developmental abnormalities such as goitre. The limestone region of Derbyshire, UK was goitre-endemic until it declined from the 1930s and the reason for this has escaped a conclusive explanation. The present study investigates the cause(s) of goitre in the UK-Peak District area through an as...

Despite reported synergies between alumina rich supplementary cementitious materials (SCMs) and limestone, previous studies have focused on up to 5% limestone content. Slag hydration in the presence of 10% limestone is reported in this paper. Hydration was followed through chemical shrinkage, calorimetry, thermal analysis, electron microscopy and X-ray powder diffraction. The results show that ...

A survey on species of the genus Zelurus Hahn, 1826 (Reduviidae) occurring in Brazilian caves is provided. Zelurus tambejua sp. n. and Zelurus gerevatinga sp. n. collected from caves in Brazil are described. Comments about the current and potential distribution of the genus as a whole and of species of Zelurus found in caves for South America are also provided.

Brazil's large territory displays significant richness in caves with about 12 thousand caves already recorded. Nevertheless, studies on bats in these environments are extremely scarce and fragmented. This study characterized the chiropteran fauna from two sandstone caves under the influence of the Belo Monte hydroelectric dam (Belo Monte UHE) in Pará, Brazil. The Kararaô and Kararaô Novo caves ...
