15 Biodiversity conservation is now about prioritisation, especially in a world with limited 16 resources and so many habitats and species in need of protection. However, we cannot 17 prioritise effectively if historical and current information on a particular habitat or species 18 remains scattered. Several good platforms have been created to help users to find, use and 19 create biodiversity ...

UNLABELLED Newly discovered fossil assemblages of small bodied Homo sapiens from Palau, Micronesia possess characters thought to be taxonomically primitive for the genus Homo. BACKGROUND Recent surface collection and test excavation in limestone caves in the rock islands of Palau, Micronesia, has produced a sizeable sample of human skeletal remains dating roughly between 940-2890 cal ybp. P...

Subterranean calcite dissolution and precipitation are often considered as strictly geochemical processes. The active involvement of microbes in these processes is commonly underestimated the literature due to general oligotrophic conditions caves, except particular cave conditions, such sulfidic caves moonmilk deposits, where presence likely plays a key role mineral deposition. Here, we study ...

Cave exploration is a popular activity in the United States that can be challenging, thrilling, and dangerous. In addition to common risks associated with caves on the mainland, caves in Hawai'i may be filled with tidal water, or contain large pools of water that are accessible only through underwater entrances. This paper will discuss common injuries in caves on the mainland United States, as ...

The aim of this study is to determine the stratigraphic position bauxite deposits in Ayrancı region, where most important mineralization Bolkardağı region located. In context, age will be determined by determining erosion surface associated with features during formation and according its side rocks. there are Permian-Cretaceous aged rocks belonging Union, one main tectonic units forming Centra...

Site geology: The geology of the Oak Park site is one of limestone-drift materials overlying regional limestone-bedrock (over which two broad groups of soils occur: light-textured gravelly soils derived from limestone, and more heavy-textured soils derived from till). The soil underlying Miscanthus-plantations used in the experiments the former type, with a perched clay/subsoil layer under the ...

We report on the determination of the spore concentration and the species composition of the airborne fungi in selected caves of the Tatra Mountains, Poland. The following caves were surveyed: Mylna, Obłazkowa, Mroźna, Zimna and Naciekowa. The sampling was carried out in July 2015 and in January 2016. The aeromycological analyses were performed with the impact method, using the Air Ideal 3P app...

The prehistory of the Mammoth Cave area has been of interest to archeologists for more than a century because of the remarkable preservation in the dry cave environment. Beginning with the antiquarian search for mummified bodies in the early nineteenth century up to the most modern scientific research, Mammoth Cave has revealed important information about the Native Americans who lived near and...

X-ray mammography is widely used for detection of breast cancer. Besides its popularity, this method did not have the potential of discriminating a tumor covered with limestone from a pure limestone mass. This might cause misdetection of some tumors covered with limestone or unnecessary surgery for a pure limestone mass. In this study, Ultra-Wide Band (UWB) signals are used for the imaging. A f...

Bacteria and archaea sustain subsurface cave ecosystems by dominating primary production and fueling biogeochemical cyclings, despite the permanent darkness and shortage of nutrients. However, the heterogeneity and underlying mechanism of microbial diversity in caves, in particular those well connect to surface environment are largely unexplored. In this study, we examined the bacterial abundan...
