Mayan Urbanism: Impact on a Tropical Karst Environment, 1979, Deevey Es, Rice Ds, Rice Pm, Vaughan Hh, Brenner M, Flannery Ms,
From the first millennium B.C. through the 9th-century A.D. Classic Maya collapse, nonurban populations grew exponentially, doubling every 408 years, in the twin-lake (Yaxha-Sacnab) basin that contained the Classic urban center of Yaxha. Pollen data show that forests were essentially cleared by Early Classic time. Sharply accelerated slopewash and colluviation, amplified in the Yaxha subbasin by urban construction, transferred nutrients plus calcareous, silty clay to both lakes. Except for the urban silt, colluvium appearing as lake sediments has a mean total phosphorus concentration close to that of basin soils. From this fact, from abundance and distribution of soil phosphorus, and from continuing post-Maya influxes (80 to 86 milligrams of phosphorus per square meter each year), which have no other apparent source, we conclude that riparian soils are anthrosols and that the mechanism of long-term phosphorus loading in lakes is mass transport of soil. Per capita deliveries of phosphorus match physiological outputs, approximately 0.5 kilogram of phosphorus per capita per year. Smaller apparent deliveries reflect the nonphosphatic composition of urban silt; larger societal outputs, expressing excess phosphorus from deforestation and from food waste and mortuary disposal, are probable but cannot be evaluated from our data. Eutrophication is not demonstrable and was probably impeded, even in less-impacted lakes, by suspended Maya silt. Environmental strain, the product of accelerating agroengineering demand and sequestering of nutrients in colluvium, developed too slowly to act as a servomechanism, damping population growth, at least until Late Classic time

Le systme souterrain du Sornin (Berger-Fromagre, Vercors, Isre), 1983, Delannoy, J. J.
THE UNDERGROUND SYSTEM OF PLATEAU DU SORNIN (VERCORS, FRANCE): THE GOUFFRE BERGER AND THE SCIALET DE LA FROMAGERE - Gouffre Berger (-1198m) and Scialet de La Fromagre (-902m) are the two main drains of an important underground complex, which develops 26 km inside Sornin table-land, massif du Vercors, Isre. The glaciers have left deep prints in the surface morphology (Schichttreppenkarst) and have played an important role in the genesis of the underground complex of Sornin. Most of morphological elements and dated witnesses (speleothems) testify to the primacy of this morphoclimatic term. Under present bioclimatic conditions (discontinuous forest - Raw weather climate, T? = 4?C, P = 1700mm), the specific dissolution is estimated to 120mm/ky. This dissolution is important in winter (2,5 times more than in summer). Sornin plateau belongs to an intermediary case between forests mountainous karsts and high karsts regarding the spatial distribution of the dissolution.

Des cavits dans la couverture limoneuse des plateaux nivernais (Nivre), 1986, Chabert, C.
CAVES IN THE SOFT COVER OF THE PLATEAUX DU NIVERNAIS (NIEVRE, FRANCE) - North of the Massif Central, around Nevers, the jurassic limestones are covered with a mio-pliocene silt mantle characterised by different caves: collapse dolines in relation with the crypto-karst situated into the underlying limestones and little holes developing in the silt mass (ex.: ponor of Bois de la Grange, length: 11 m). The tertiary mantle and the forests take a prominent part in the regulation and the physico-chemistry of karst waters.

Origination of stone forests in China., 1986, Song Linhua
The stone forests are widely distributed in the tropical and subtropical climatic areas. The stone forests may be divided into hilltop stone forest, hill slope stone forest and the stone forest in the depressions or valleys. The conditions for stone forest development should be (1) thick and pure limestone, (2) gentle dipping of limestone formation, generally less than 150, (3) a lot of vertical joint and fissure networks, (4) the soil covering on the limestone surface inhomogeneous, thick in the fissures and thin on the rock top surface, and (5) the soil should be wet and contain rich organic materials and CO2. In the above conditions, the stone teeth may develop to the stone forest. If lack of organic soil, low humidity and stable depth of soil erosion zone occurs, only the stone teeth are developed.

Groundwater chemistry and cation budgets of tropical karst outcrops, Peninsular Malaysia, I. Calcium and magnesium, 1989, Crowther J,
The discharge and chemical properties of 217 autogenic groundwaters were monitored over a 1-yr period in the tower karsts of central Selangor and the Kinta Valley, and in the Setul Boundary Range. Because of differences in soil PCO2, calcium concentrations are significantly higher in the Boundary Range (mean, 82.5 mg l-1) than in the tower karst terrain (44.6 mg l-1). Local differences in both source area PCO2 and amounts of secondary deposition underground cause marked intersite variability, particularly in the tower karst. Dilution occurs during flood peaks in certain conduit and cave stream waters. Generally, however, calcium correlates positively with discharge, since the amount of secondary deposition per unit volume of water decreases at higher flows. Magnesium concentrations and Mg:Ca Mg ratios of groundwaters are strongly influenced by bedrock composition, though bedrock heterogeneity and the kinetics and equilibria of carbonate dissolution reactions preclude extremely low or high Mg:Ca Mg values. Net chemical denudation rates range from 56.6 to 70.9 m3km2yr-1.The results are considered in relation to cation fluxes in surface runoff, soil throughflow and nutrient cycling. Preliminary calcium and magnesium budgets show that (1) dissolutional activity is largely confined to the near-surface zone; and (2) the annual uptake of calcium and magnesium by tropical limestone forests is similar in magnitude to the net solute output in groundwaters

Les montagnes refuges calcaires de Mditerrane orientale et du Moyen-Orient (Grce, Crte, Turquie, Iran), 1990, Maire, R.
The mountain shelters in the karst regions of Greece, Crete, Turkey and Iran - The concept of mountain shelters in karst region exists from the Prehistory, especially with rock-shelters and karstic caves. In the high karsts of Greece, Crete, Taurus (Turkey) and Zagros (Iran), the highlanders have survived during the invasions and wars because of their natural bastions. At the junction of civilisations and religions (Christians and Moslems), the karst biotope, one of the natural environment the most used by human people to guard against enemy and to breed (sheep-farming). Because of grazing and destruction of forests (particularly by Byzantine people and Venitians), the mediterranean karst mountain grew poorer.

Abstract: Eastern Australian Quaternary mammal faunas: their palaeoclimatic and faunistic setting - and their potential IN: Proceedings of the Wombeyan Karst Workshop November 19-22, 1993 , 1993, Ride, W. D. L.

The availability of extensive palaeoclimatic information and the realisation that the cave deposits of eastern Australia extend back into the Tertiary, and the recognition that virtually the whole of the characteristic marsupial fauna are arid adapted, it seems likely that the caves have the potential to illustrate the whole of the spectacular and rapid Australian radiation after the loss of the rainforests.

Les Forts de Pierre ou Stone forests de Lunan (Yunnan, Chine), 1996, Ford D. , Salomon J. N. , Williams P.
"Stone forests " are well known in Southern China. We describe the type site in Lunan County on the Yunnan Plateau at about 1800 m. "Stone forests " are a spectacular form of karren, similar to the "tsingy" of Madagascar or pinnacles of Mulu. In Yunnan they are developed in massive Permian limestones and dolomites. The "Stone forests" are high fluted towers, typically more ruiniform in dolostones, that attain 20-30m in height, exceptionally 40m. They occur in patches of several square kilometres in extent in a rolling polygonal karst landscape with about 150 m local relief Three phases of evoluti6n are recognized spanning 250 Ma from the Permian until the present: 1) Mid Permian karstification and burial by Upper Permian continental basalts, 2) Mesozoic erosion and re-karstification, then burial in the Eocene by thick continental deposits, 3) Late Tertiary and Quaternary exhumation and re-karstification. No other "Stone forests" in the world show this complexity of evolution.

The Hawaiian cave planthoppers (Homoptera: Fulgoroidea: Cixiidae); A model for rapid subterranean speciation?, 1997, Hoch Hannelore
After the successful colonization of a single ancestral species in the Hawaiian Islands, planthoppers of the cixiid genus Oliarus underwent intensive adaptive radiation resulting in 80 described endemic species. Oliarus habitats range from montaneous rain forests to dry coastal biotopes and subterranean environments. At least 7 independant evolutionary lines represented by different species have adapted to lava tubes on Molokai (1), Maui (3), and Hawaii Island (3). Behavioral and morphological studies on one of these evolutionary lines on Hawaii Island, the blind, flight- and pigmentless Oliarus polyphentus have provided evidence for reproductive isolation between allopatric populations which may in fact be separate species. Significant differences in song parameters were observed even between populations from neighbouring lava tubes, although the planthoppers are capable of underground migration through the voids and cracks of the mesocavernous rock system which is extant in young basalt: after a little more than 20 years, lava tubes within the Mauna Ulu 1974 flow had been colonized by O. 'polyphenius" individuals, most probably originating from a near-by forestkipuka. Amazingly, this species complex is found on the youngest of the Hawaiian Islands, with probably less than 0.5 m.y., which suggests rapid speciation processes. Field observations have led to the development of a hypothesis to match underground speciation with the dynamics of vegetational succession on the surface of active volcanoes. Planthopper range partitioning and geographic separation of populations by young lava flows, founder events and small population size may be important factors involved in rapid divergence.

Deforestation in the Dominican Republic: a village-level view, 1997, Brothers Ts,
Deforestation is still rapid in some parts of the Caribbean, though it has attracted much less attention than deforestation in mainland Latin America. This paper examines the history and causes of the recent rapid deforestation of a lowland karst region of the Dominican Republic in the light of models derived from studies in Central America and the Amazon. Investigation was limited to the vicinity of a single village (Los Limones). Information was drawn from interviews, questionnaires and ground reconnaissance, in addition to archival information and aerial photographs. Deforestation at Los Limones involved many of the same elements seen in mainland deforestation, including construction of access roads, spontaneous agricultural colonization, and pasture conversion, but it followed no single mainland model. Logging, not normally emphasized as a cause of Latin American deforestation, played an important role in opening up the forest to agricultural settlement. Pasture conversion was not a matter of aggregation of large ranches by wealthy absentee landowners, as in the Amazon, but apparently a local response to the economic and ecological advantages of cattle raising. Government actions strongly influenced deforestation, but not via colonization schemes or economic subsidies for cattle ranching; the rhythm of deforestation at Los Limones was tied to the monopolistic practices of the dictatorship of Rafael Trujillo and the social disorganization following his assassination. The national government in fact bears the primary responsibility for deforestation of Los Haitises, a conclusion that contradicts the government's own suggestion that the destruction was largely carried out by poor farmers. Prospects for rehabilitation of the deforested area are gloomy because of the extent of ecological damage and the continued adversarial relationship between the government and the rural population

Land use in the karstic lands in the Mediterranean region, 1999, Atalay Ibrahim
Karstic lands have special importance in terms of soil formation and land-use. Soil appears only on the flat and slightly undulating karstic lands, while soils are found along the cracks and bedding surfaces between the layers on the hilly karst areas although these lands are rocky in appearance. Karstic lands in the hilly area are not conducive to cultivation. But rocky areas create a favourable habitat for the growth of forests except in an arid climate. Because the tree roots easily follow and develop along the cracks in the limestone. As a general rule soil erosion does not occur on sub-horizontal karst surfaces due to the fact that atmospheric waters easily infiltrate along the cracks. Natural generation of vegetation like the maquis-type occurs via the root suckers, but coniferous trees such as cedar, fir, pine through seed dispersal. The clearance of natural vegetation on the karstic lands leads to the formation of bare lands. That is why the slopes of the limestone hillsides have been converted into bare and/or rocky terrains in places where natural vegetation has been completely destroyed.

Agriculture and nature conservation in the Moravian karst (Czech Republic), 1999, Balk Ivan, Bosk Pavel, Jano Jozef, Stefka Leos
Moravian Karst is a narrow strip of limestone with long history of settlement, agricultural use and man impact to karst. It is naturally divided into smaller units; karst plateaus; separated by deep valleys (glens). Each plateau has different proportion of land use, i.e. the percentage of agricultural land, forests, etc. The agricultural land constitutes now up to 70% in the north and max. 30% in the centre and south of the total area of plateaus. Intensive agricultural use of the arable land since 60ties of this Century caused great impact to quality of soils and groundwater by overdoses of fertilisers and other artificial chemical substances. Detailed research in 1980 to 1997 resulted in a plan of care based on the zonation of land. There were defined zones with different degree of restriction of land use, agricultural activities and application of fertilisers and biocides. Arable lands has been gradually changed to meadows and pastures by introduction of grass since 1987 in the most strictly protected zone to protect especially subsurface karst forms.

Water vulnerability assessment in karst environments: a new method of defining protection areas using a multi-attribute approach and GIS tools (EPIK method), 1999, Doerfliger N, Jeannin Py, Zwahlen F,
Groundwater resources from karst aquifers play a major role in the water supply in karst areas in the world, such as in Switzerland. Defining groundwater protection zones in karst environment is frequently not founded on a solid hydrogeological basis. Protection zones are often inadequate and as a result they may be ineffective. In order to improve this situation, the Federal Office for Environment, Forests and Landscape with the Swiss National Hydrological and Geological Survey contracted the Centre of Hydrogeology of the Neuchatel University to develop a new groundwater protection-zones strategy in karst environment. This approach is based on the vulnerability mapping of the catchment areas of water supplies provided by springs or boreholes. Vulnerability is here defined as the intrinsic geological and hydrogeological characteristics which determine the sensitivity of groundwater to contamination by human activities. The EPIK method is a multi-attribute method for vulnerability mapping which takes into consideration the specific hydrogeological behaviour of karst aquifers. EPIK is based on a conceptual model of karst hydrological systems, which suggests considering four karst aquifer attributes: (1) Epikarst, (2) Protective cover, (3) Infiltration conditions and (4) Karst network development. Each of these four attributes is subdivided into classes which are mapped over the whole water catchment. The attributes and their classes are then weighted. Attribute maps are overlain in order to obtain a final vulnerability map. From the vulnerability map, the groundwater protection zones are defined precisely. This method was applied at several sites in Switzerland where agriculture contamination problems have frequently occurred. These applications resulted in recommend new boundaries for the karst water supplies protection-zones

Forest recovery in abandoned agricultural lands in a karst region of the Dominican Republic, 2000, Rivera L. W. , Zimmerman J. K. , Aide T. M. ,
This study documents the status of forest vegetation in the karst region of Los Haitises National Park, Dominican Republic, following the abandonment of pastures (less than or equal to 5 years), young (less than or equal to 5 years) 'conucos' (mixed plantings), old (7-30 years) conucos, and cacao plantations (> 25 years). We compared these sites to vegetation characteristics of patches of forest in karst valleys ('old forest'-too old to know their exact land use) and on mogote tops with no recent history of human disturbance. The youngest sites date to when squatters were removed from Los Haitises National Park. Forest structure (density, basal area, and species richness of woody plants greater than or equal to 1 cm DBH) were all significantly affected by land use. Density was highest in intermediate-aged valley sites (old conucos) and mogote tops, while both basal area and species richness tended to increase with age of abandonment. Although cacao plantations had been abandoned for more than 25 years the species diversity was low, due to continued regeneration of this persistent crop. Abandoned pastures had the greatest nonwoody biomass and were dominated by the fern Nephrolepis multiflora which had completely replaced pasture grasses. An ordination of the woody plant communities separated the mogote tops from valleys, emphasizing the strong control that topography has on the forest community in moist and wet tropical forests on karst substrates. Valley sites were arranged in the ordination in order of their age, suggesting a successional sequence converging on the composition of the 'old forest' sites

Shape and rock relief of pillars in Naigu Stone Forest (SW China), 2001, Knez Martin, Slabe Tadej

Stone forests have evolved from underground karren. The shape of rock pillars and their rock relief are controlled by different rock beds where they developed at various levels and by underground factors and rainwater.
