%T Ecology of the hyporheic zone: a review
%A Octavian PACIOGLU
%X It is widely recognized that the hyporheic zone is a crucial component of river ecosystems, structurally and functionally. This article provides a contemporary review outlining the historical development of research in the field and an overview of the current state of knowledge regarding the structure and functioning of hyporheic invertebrate assemblages. The paper makes a call for a more holistic approach to the study of the hyporheic zone and the invertebrate communities that inhabit it.

%T Karst and caves of Palau
%A Tony WALTHAM
%X The Rock Islands of Palau, in the western Pacific Ocean, constitute a partially drowned fengcong karst with forest-covered conical hills that now form numerous islands. The karst is unusual in that many of the hills are coalesced into long sinuous ridges, which might be inherited from pre-karstic marine erosion. Known caves within the Palau karst are all short, consisting of truncated old chambers and also tidal caves through to hong lakes in flooded dolines.

%T Interim report on a geoarchaeological project in the karstic region of the Serranía de Cuenca (central Spain)
%A Alfonso BENITO-CALVO, Ignacio DE LA TORRE
%X The Serranía de Cuenca (Iberian Chain, Central Spain) is dominated by calcareous plateaus and canyons with abundant karstic landforms, such as caves and rock-shelters. These features contribute to giving the Serranía de Cuenca great potential as a locality for research into the Palaeolithic. In 2008 we started a geoarchaeological project in this region, in order to investigate aspects of human settlement in Central Iberia during the Pleistocene. The first stages of the project sought to determine the karstic locations most likely to include archaeological sites, by making use of indexes and GIS map analysis. This approach produced digital maps and databases of potential locations that are now being used as a basis for follow-up field surveys. The combination of laboratory and field surveys has yielded interesting preliminary results, leading to the recognition of large rock-shelters with thick Pleistocene deposits, whose archaeological potential will be tested in the next stage of the project.

%T A high-resolution spatial survey of cave air carbon dioxide concentrations in Scoska Cave (North Yorkshire, UK): implications for calcite deposition and re-dissolution
%A Tom WHITAKER, Daniel JONES, James U L BALDINI, Alex J BAKER
%X Carbon dioxide concentration variability in caves has implications for palaeoclimatic research involving stalagmites, the conservation of cave art, condensation corrosion, and safety during cave exploration. Here we present a high-resolution spatial survey of cave air carbon dioxide partial pressure (PCO2) in the 1.5km Scoska Cave system in North Yorkshire, UK, constructed using measurements taken during the interval of July 1 to July 5, 2008.
%X According to the spatial P-CO2 survey, 76% of the cave air P-CO2 increase occurred within the first ~50 metres; consequently the P-CO2 gradient throughout the rest of the cave was slight. As is the case in other caves, this suggests that a 'front' exists at this site between high P-CO2 cave air and low P-CO2 outside air, where the P-CO2 increases dramatically over a short distance. Temperature data support this interpretation. This CO2 'front' is thought to represent the farthest point reached by large-scale advection of air out of the cave, and its position is hypothesized to fluctuate depending on atmospheric conditions. Thus, distinct P-CO2 trends characterize sections of the Scoska Cave system, which result in spatial variability in calcite deposition and redissolution.
%X Modelled stalagmite growth rates vary between negligible and 0.21 mm yr-1, depending on unconstrained drip water [Ca2+] values and cave atmosphere P-CO2. Assuming constant drip water [Ca2+], optimum calcite deposition occurs near to the cave entrance, where ventilation and advection reduce P-CO2 levels most effectively. However, calcite precipitation on the roof of the cave may partially control the [Ca2+] of drip water that reaches the floor, so although the link between overall calcite deposition (i.e., on the roof and the floor) and P-CO2 appears robust, the effect of variable cave air P-CO2 on stalagmite growth rates requires more research. These calculations suggest that calcite precipitation rates in different areas of Scoska Cave may differ due to local P-CO2 and temperature variability, highlighting the benefits of thoroughly understanding site-specific cave environmental factors prior to the interpretation of stalagmite-based palaeoclimate records.
