“…Indeed, Moldovan et al (2012) plead against the theory of accidental downward drift of individuals when voids are flooded and more for an active drift when water floods the voids; hence, water intermittency might act as the main driver of epikarst drip diversity.…”

“…For instance, in the Slovenian epikarst system, Brancelj (2002) recorded one cyclopoid and eleven harpacticoid taxa (including one Parastenocarididae) from 19 puddles and basins on eight sampling dates in Velika Pasjica, a 75 m long cave with ceiling thickness ranging from 2 to 10 m; Moldovan et al (2012) recorded 4 species of harpacticoids (including one Parastenocarididae) and one cyclopoid from seven drips in Ciur Izbuc Cave in Transylvania (Romania), in the 425 m long active branch of the cave; Pipan et al (2007b) recorded seven species of harpacticoids (including two Parastenocarididae) and three of cyclopoids from 13 ceiling drips in Organ Cave, West Virginia, a very large cave, but in a section with a ceiling thickness of 25 m.…”

“…Moldovan, and her colleagues initiated an intensive study of Romanian caves in the mid 2000's, emphasizing community structure and diversity (Meleg et al, 2011a(Meleg et al, , 2011b, as well as effects of habitat fragmentation and quality (Moldovan et al, 2011). During the same time period, colleagues (2007, 2010) integrated epikarst into models of organic carbon flux in caves, and provided the first measurements of dissolved organic carbon.…”

“…Higher conductivity implies longer residence time of the water in epikarst as the water becomes saturated with CaCO 3 (Covington et al, 2012). Moldovan et al (2011) have made important steps in understanding why different epikarst communities are different, not just that they are different. Working in Peştera Ciur Izbuc in Romania, they used a combination of stable isotopes, drip rates, and species composition in abundance, to understand differences between the epikarst community in two sections of the cave 300 m apart.…”

“…Second, understanding the reasons for the differences in species composition and richness of epikarst communities, especially in small scale, is an obvious next step forward. The promising start of Moldovan et al (2011), one that combines hydrological, biological, and stable isotope data, should be expanded. Third, none of the epikarst fauna has been put in a phylogenetic context.…”

Epikarst is not only an important component of the hydrogeology of karst and an active site of speleogenesis, it is habitat for a number of species adapted to subterranean life. Water in epikarst, with a residence time of days to months, is a highly heterogeneous habitat, and the animals are primarily sampled from continuously sampling dripping water or collecting from residual drip pools. While the subterranean fauna of cracks and crevices has been known for over 100 years, it is only in the past several decades that epikarst has been recognized as a distinct habitat, with reproducing populations of stygobionts. Dissolved organic carbon in epikarst drip water is a primary and sometimes the only source of organic matter for underlying caves, especially if there are not sinking streams that enter the cave. Typical concentrations of organic carbon are 1 mg L-1. The fauna of epikarst is dominated by copepods, but other groups, including some terrestrial taxa, are important in some areas. Most of the diversity is β-diversity (between drips and between caves). In Slovenia, an average of nearly 9 stygobiotic copepod species were found per cave. In studies in Romania and Slovenia, a number of factors have been found to be important in determining species distribution, including ceiling thickness, habitat connectivity and habitat size. In addition to eye and pigment loss, epikarst copepod species may show a number of specializations for life in epikarst, including adaptations to avoid displacement by water flow. Several geoscientists and biologists have challenged the uniqueness and importance of epikarst, but on balance the concept is valid and useful. Fruitful future research directions include development of better sampling techniques, studies to explain differences among nearby epikarst communities, phylogeographic studies, and assessing the possible role of copepods as tracers of vadose water

Ancient human footprints in Ciur‐Izbuc Cave, Romania

In 1965, Ciur-Izbuc Cave in the Carpathian Mountains of Romania was discovered to contain about 400 ancient human footprints. At that time, researchers interpreted the footprints to be those of a man, woman and child who entered the cave by an opening which is now blocked but which was usable in antiquity. The age of the prints (≈10-15 ka BP) was based partly on their association with cave bear (Ursus spelaeus) footprints and bones, and the belief that cave bears became extinct near the end of the last ice age. Since their discovery, the human and bear evidence and the cave itself have attracted spelunkers and other tourists, with the result that the ancient footprints are in danger of destruction by modern humans. In an effort to conserve the footprints and information about them and to reanalyze them with modern techiques, Ciur-Izbuc Cave was restudied in summer of 2012. Modern results are based on fewer than 25% of the originally described human footprints, the rest having been destroyed. It is impossible to confirm some of the original conclusions. The footprints do not cluster about three different sizes, and the number of individuals is estimated to be six or seven. Two cases of bears apparently overprinting humans help establish antiquity, and C-14 dates suggest a much greater age than originally thought. Unfortunately, insufficient footprints remain to measure movement variables such as stride length. However, detailed three-dimensional mapping of the footprints does allow a more precise description of human movements within the cave.
