Karst Research Institute at ZRC SAZU, Postojna, Slovenia is searching a candidate for an AXA postdoctoral grant.
Thanks to efforts of Dr. Oana Moldovan from the Institutul de Speologie "Emil Racovita" (Romania), the entire content of the “Subterranean Biology” journal is now represented at the KarstBase and its “World Cave and Karst Science journals” sub-system
Currently, the Indonesian cavers running the mini project to show the distribution of caves in Indonesian karst. The project, so called CavesID, is a voluntary project gathering all the information about the caves in Indonesia.
The Journal "Speleogenesis and Evolution of Karst Aquifers" ceased publication with the Issue 12, 2012

That holokarst is 1. karst area with little or no surface runoff or streams; it is underlain by thick carbonate rocks and is characterized by well developed karst surface topography from karren to poljes, extensive subsurface karst features like caves, caverns, galleries, chimneys, etc . 2. cvijic's term for a karst area like that of the dinaric karst of slovenia. such areas have bare surfaces on thick deposits of limestone that extend below sea level, well developed karren, dolines, uvalas, poljes, deep ponors, and extensive cave systems; they have little or no surface drainage . synonyms: (french.) holokarst; (german.) holokarst; (greek.) holokarst; (italian.) olocarsismo, carsismo, maturo; (spanish.) holokarst; (turkish.) tam karst; (yugoslavian.) potpuni krs (kras), holokarst. contrast causse, merokarst.?

The Totes Gebirge is the largest karst massif in the Northern Calcareous Alps (NCA). This paper focuses on the eastern part, where two major multiphase alpine cave systems (Burgunderschacht Cave System and DÖF–Sonnenleiter Cave System) are described with respect to morphology, hydrology, and sediments. The caves consist of Upper Miocene galleries of (epi)phreatic genesis and younger vadose canyon-shaft systems. Morphometrical analyses were used to determine the relevance of (1) cave levels (horizontal accumulations of galleries), (2) slightly inclined palaeo water tables of speleogenetic phases, (3) initial fissures, and (4) inception horizons on the development of the cave systems. (Epi)phreatic cave conduits developed preferentially along vertical faults and along only a restricted number of bedding planes, which conforms to the inception horizon hypothesis. For at least one of the systems, a development under epiphreatic conditions is certain and a hydrological behaviour in the “filling overflow manner” is likely.
Observations in further major cave systems in the Totes Gebirge identify palaeo water tables of speleogenetic phases that show inclinations of 1.5° ± 1°. Analyses of cave levels reveal distinct peaks for each cave but it is hardly possible to correlate these elevation levels between caves of different parts of the karst massif. Therefore, we conclude that cave levels (strictly horizontal) indicate speleogenetic phases or palaeo water tables respectively, but they cannot be correlated with palaeo base levels or on regional scale. An exact correlation between cave development and palaeo base levels at the surface is only possible with inclined palaeo water tables of speleogenetic phases.
For the Totes Gebirge, the inclination directions of the speleogenetic phases imply that palaeo drainage was radial and recharge was autogenic, which is in contrast to observations from other plateaus in the NCA. Differences in fracture properties seem to be the reason for the development of divergent types, according to the Four State Model. A simplified model for cave genesis and surface development in this area since the Upper Miocene is presented.
