Speleothems and paleoglaciers, , Spotl Christoph, Mangini Augusto,
Ice and speleothems are widely regarded as mutually exclusive as the presence of liquid water is a fundamental prerequisite for speleothem deposition. Here we show that speleothems may form in caves overlain by a glacier, as long as the temperature in the cave is above freezing and the conduits are not completely flooded by melt water. Carbonate dissolution is accomplished via sulfide oxidation and the resultant speleothems show high [delta]13C values approaching and locally exceeding those of the parent host rock (lack of soil-derived biogenic C). The [delta]18O values reflect the isotopic composition of the melt water percolating into the karst fissure network and carry an atmospheric (temperature) signal, which is distinctly lower than those of speleothems formed during periods when soil and vegetation were present above the cave. These `subglacial' speleothems provide a means of identifying and dating the former presence of warm-based paleoglaciers and allow us to place some constraints on paleotemperature changes

Paleoclimate and location of the border between Mediterranean climate region and the Saharo-Arabian Desert as revealed by speleothems from the northern Negev Desert, Israel, , Vaks A. , Barmatthews M. , Ayalon A. , Matthews A. , Frumkin A. , Dayan U. , Halicz L. , Mogilabin A. , Schilman B. ,
Speleothem bearing karstic caves of the northern Negev Desert, southern Israel, provides an ideal site for reconstructing the paleoclimate and paleo-location of the border between Mediterranean climate region and the Saharo-Arabian Desert. Major periods of speleothem deposition (representing humid periods) were determined by high resolution 230Th-U dating and corresponding studies of stable isotope composition were used to identify the source of rainfall during humid periods and the vegetation type. Major humid intervals occurred during glacials at 190-150[no-break space]ka, 76-25[no-break space]ka, 23-13[no-break space]ka and interglacials at 200-190[no-break space]ka, 137-123[no-break space]ka and 84-77[no-break space]ka. The dominant rainfall source was the Eastern Mediterranean Sea, with a possible small contribution from southern tropical sources during the interglacial periods. When the interglacial interval rainfall was of Eastern Mediterranean origin, the minimum annual rainfall was ~ 300-350[no-break space]mm; approximately twice than of the present-day. Lower minimum amounts of precipitation could have occurred during glacial periods, due to the cooler temperatures and reduced evaporation. Although during most of the humid periods the vegetation remained steppe with mixed C3 C4 vegetation, Mediterranean C3 type steppe-forest vegetation invaded southward for short periods, and the climate in the northern Negev became closer to Mediterranean type than at present. The climate was similar to present, or even more arid, during intervals when speleothem deposition did not occur: 150-144[no-break space]ka, 141-140[no-break space]ka, 117-96[no-break space]ka, 92-85[no-break space]ka, 25-23[no-break space]ka, and 13[no-break space]ka-present-day.Precipitation increase occurred in the northern Negev during the interglacial monsoonal intensity maxima at 198[no-break space]ka, 127[no-break space]ka, 83[no-break space]ka and glacial monsoonal maxima at 176[no-break space]ka, 151[no-break space]ka, 61[no-break space]ka and 33[no-break space]ka. However, during interglacial monsoonal maxima at 105[no-break space]ka and 11[no-break space]ka, the northern Negev was arid whereas during glacial monsoonal minima it was usually humid. This implies that there is not always synchroneity between monsoonal activity and humidity in the region.Oxygen isotopic values of the northern Negev speleothems are systematically lower than contemporaneous speleothems of central and northern Israel. This part is attributed to the increased rainout of the heavy isotopes by Rayleigh fractionation processes, possibly due to the farther distance from the Mediterranean coast

The `human revolution' in lowland tropical Southeast Asia: the antiquity and behavior of anatomically modern humans at Niah Cave (Sarawak, Borneo), , Barker G, Barton H, Bird M, Daly P, Datan I, Dykes A, Farr L, Gilbertson D, Harrisson B, Hunt C,
Recent research in Europe, Africa, and Southeast Asia suggests that we can no longer assume a direct and exclusive link between anatomically modern humans and behavioral modernity (the `human revolution'), and assume that the presence of either one implies the presence of the other: discussions of the emergence of cultural complexity have to proceed with greater scrutiny of the evidence on a site-by-site basis to establish secure associations between the archaeology present there and the hominins who created it. This paper presents one such case study: Niah Cave in Sarawak on the island of Borneo, famous for the discovery in 1958 in the West Mouth of the Great Cave of a modern human skull, the `Deep Skull,' controversially associated with radiocarbon dates of ca. 40,000 years before the present. A new chronostratigraphy has been developed through a re-investigation of the lithostratigraphy left by the earlier excavations, AMS-dating using three different comparative pre-treatments including ABOX of charcoal, and U-series using the Diffusion-Absorption model applied to fragments of bones from the Deep Skull itself. Stratigraphic reasons for earlier uncertainties about the antiquity of the skull are examined, and it is shown not to be an `intrusive' artifact. It was probably excavated from fluvial-pond-desiccation deposits that accumulated episodically in a shallow basin immediately behind the cave entrance lip, in a climate that ranged from times of comparative aridity with complete desiccation, to episodes of greater surface wetness, changes attributed to regional climatic fluctuations. Vegetation outside the cave varied significantly over time, including wet lowland forest, montane forest, savannah, and grassland. The new dates and the lithostratigraphy relate the Deep Skull to evidence of episodes of human activity that range in date from ca. 46,000 to ca. 34,000 years ago. Initial investigations of sediment scorching, pollen, palynomorphs, phytoliths, plant macrofossils, and starch grains recovered from existing exposures, and of vertebrates from the current and the earlier excavations, suggest that human foraging during these times was marked by habitat-tailored hunting technologies, the collection and processing of toxic plants for consumption, and, perhaps, the use of fire at some forest-edges. The Niah evidence demonstrates the sophisticated nature of the subsistence behavior developed by modern humans to exploit the tropical environments that they encountered in Southeast Asia, including rainforest

The microvegetation of a small Ice-cave in Hungary., 1964, Kol Erzsebet
The algal flora of a small, artificial, ice-cave located in Northern Hungary is described. In this cave 23 species of algae (see in Table 3) were found of which the Cyanophyta and Chlorophyta occurred with approximately equal number. (9 vers. 11) It was found that the primary limiting factor influencing the penetration of the algae into the cave is the low temperature and not the lack of light.

Preliminary note on the Algae of Crystal Cave, Kentucky., 1965, Nagy J. P.
Collections of a preliminary type carried out in Crystal Cave, Kentucky, resulted in the identification of seven algal taxa. A Chamaesiphon (Dermocarpales) and an Asterocytis (Bangioidea) are reported for the first time from a speleo-environment. As no correlation could be found among the algae occurring in Crystal Cave and those of nearby Mammoth Cave the conclusion is reached that the cave algal floras do not originate from the algal vegetation of the surface but may have gotten into the caves at the time of the latter's formation.

The world of plants in caves of Lillafured (Hungary)., 1965, Verseghy Klara
The vegetation of the Forrs and Istvn caves at Lillafured in Hungary is composed of algae, micro- and macrofungi and mosses. The algae in both caves are represented by unicellular Cyanophyta and Chlorophyta with small species numbers. The macrofungi are Coprinus and Polyporacea spp. while it was impossible to identify the microfungi. The moss flora is richly developed and it can be supposed to represent a secondary vegetation at the artificially illuminated places of the caves. In Forrs cave 7, and in Istvn cave 15 different mosses were found, only 3 of which proved to be common to both caves: Rhynchostegium murale, Eucladium verticillatum and Pohlia sp. A rare and interesting species: Fissidens minutulus occurred at several localities in Forrs cave.

Sporomorphs From The Dessicated Carcases of Mammals From Thylacine Hole, Western Australia, 1969, Ingram, B. S.

Assemblages of sporomorphs have been recovered from the gut content of dessicated mammalian carcases of ages estimated up to 5,000 years BP, found in Thylacine Hole, a cave in the Eucla Basin. These assemblages suggest the animals lived in an area of vegetation similar to that existing around the cave at present.

The Migration of Cave Arthropods Across The Nullarbor Plain, Southern Australia, 1972, Richards, Aola, M.

The Nullarbor Plain is a low plateau of Tertiary limestone covering an area of 194,175 km2 in southern Australia. It has a semi-arid climate and supports a stunted vegetation. Ninety-five species of arthropods have been recorded from 47 Nullarbor caves, and many of these species are widely distributed across the Plain. Two possible explanations for their distribution are discussed. Subterranean migration may occur through the widespread zone of small interconnecting cavities in the Nullarbor Limestone, but this has not yet been confirmed. While cave arthropods are confined to the cool, moist cave environment during the day, they have been observed at night in cave entrances, in dolines and on the surface of the Plain. Cave "breathing", similarity in cave and epigean climate at night, strong winds, occasional heavy rain and numerous animal burrows all contribute towards favourable conditions for surface migration.

The Spider communities in tropical caves (Aranaea)., 1973, Brignoli Paolo Marcello
The so called "tropical" caves (most of which are also geographically "tropical") are distinguished from the "temperate" caves by the much larger trophic resources. Spiders are common in both kinds of caves, but the groups present in one kind are mostly absent in the other (notwithstanding that many families are distributed over at least one temperate and one tropical region). As in all temperate caves more or less the same groups of spiders can be found, so the tropical caves have a typical spider fauna, composed of different groups (often also more than those present in the temperate caves). In the temperate caves the most typical groups are the Leptonetidae, the Dysderidae, many Araneoidea and some Agelenidae; these groups are either absent or rare in the tropical caves. In these the typical groups are some Orthognatha and many primitive spiders of the Haplogynae (Oonopidae, Tetrablemmidae, Ochyroceratidae, Scytodidae, Pholcidae, Telemidae) with a few Araneoidea (Theridiosomatidae and Symphytognathidae). From an ecological point of view, the detriticolous groups are not common in temperate caves, but are exceedingly common in tropical caves. In these live also often some groups which could be considered not strictly detriticolous, but more exactly "microcavernicolous" (i.e. living "normally" in more or less permanent crevices etc. of soil and rocks). In temperate caves are on the other hand more common groups living typically on vegetation, not very close to the soil. Ethologically, in tropical caves the existence of groups is possible which either ambush their prey or search for it actively whereas most spiders of temperate caves capture it with a web.
