The influence of natural factors such as bioturbation or sediment movement caused by wind and water is a perennial concern for Stone Age site selection subsequent interpretation. This paper discusses the spatial artefact distribution five recently excavated, open-air exposed Middle (MSA) sites in Ntwetwe Pan, Botswana. finds comprise lithic assemblages dominated MSA points, manufactured variety...

For large fishes, seagrass canopies typically provide a relatively flat habitat on seabeds, but seagrasses in the genus Posidonia can provide additional habitat complexity by forming organic-rich deposits known as mats. Erosional processes can scour channels through the mats, resulting in the formation of escarpments with caves. Here we report that reef fishes, such as groupers, inhabit the cav...

We describe a new species of the genus Endecous Saussure (1878), recorded at the Lapa do Cipó and Olhos d'Água caves, which are located in the Itacarambi municipality, Minas Gerais state, Eastern Brazil. Another species, E. aguassay Mews, 2008 was recordedin the surroundings of the caves. The genus Endecous corresponds to the most common cricket in Brazilian hypogean environments. In general, t...

Since 2009, disasters have displaced each year at least 15 million people worldwide. Immediately post-disaster, emergency shelters serve those displaced. The sheltering system often consists of formal (managed by the government) and spontaneous volunteers). These two types may offer different resources with atmospheres that can vary widely. Displaced persons select between based on their person...

The Earth's crust hosts a subsurface, dark, and oligotrophic biosphere that is poorly understood in terms of the energy supporting its biomass production and impact on food webs at the Earth's surface. Dark oligotrophic volcanic ecosystems (DOVEs) are good environments for investigations of life in the absence of sunlight as they are poor in organics, rich in chemical reactants and well known f...

Algeria displays various karst landscapes due to its diversity in lithology, relief, age and climate. On 16th June 1988, the northwest of Algeria, a 60 m wide sudden collapse occurred Chelif Basin about 1 km north marginal carbonate platform. Despite this large event visible dissolutions platform, region has not been classified among areas yet. Our study focuses on Messinian carbonates that for...

Waterstrat et al. (JCKS (2010), 72 (2) 61–74) compared means of geometric measurements of sea and flank margin caves with the Student t-test and concluded that these different types of caves could be ‘‘statistically differentiated.’’ However, their use of the t-test is dependent on the data being normally distributed. The data that were analyzed, cave area to perimeter ratio, entrance-width to ...
