Abstract The present study analyzes fractal dimensions for the daily discharge data series of 12 karstic springs registered over two decades in Northeast Hungary. Fluctuation observed is frequent and irregular, producing rough time series. level roughness measured by dimension defined different ways corresponds to intensity fluctuation. That, turn, results from structure aquifer, its conduits’ ...

Abstract This paper describes the relation of noble gas temperature (NGT) and mean annual air (MAAT) soil (MAST) through studying water samples meteorological data from six Hungarian regions. Alluvial plains, hilly mountainous regions were studied to investigate effects geomorphological, hydrogeological micro-climatic conditions. Water collected springs wells fed different aquifers. Comparing N...

Cryogenian snowball Earth glaciations may have had disastrous impacts on the biosphere, particularly terrestrial ecosystem. However, how ecosystem responded to and recovered from these remains poorly understood. Speleothems offer important insights into life because their formation is critically dependent soil CO2 derived microbial respiration. Here we report wide distribution of miniature pale...

A case study is presented that characterizes the hydrogeology of a karstic aquifer system nearby the city of Izmir, Turkey. The main objective of this study is to provide an assessment on the spatial distribution of specific groundwater quality parameters, and to gain insight into their temporal evolution. The study area is the Nif Mountain karstic aquifer system located to the southeast of the...

the study of karst phenomena and its potentials has had always a particular importance in semi-arid zones of iran, specifically due to the lack of water sources. in this paper, we are going to discuss the landscape morphology in karstic areas, and the way we can have an ecological planning approach to it. maharlu karst basin was selected as the case study of karstic area, and kaftarak mount in ...

Giraffaphaenops yangi n. sp. is described from a limestone cave named Shizikou Dadong, Tianlin County, northwestern Guangxi, China. It is the second species of this genus, which is the most morphologically modified in the tribe Trechini in terms of troglobiomorphy. So far, Giraffaphaenops ranges in a small karstic area in northwestern Guangxi. Of the two known species, G. clarkei Deuve, 2002 wa...

Domene (Lathromene) lusitanica n. sp. from Sicó karstic massif in Portugal is described and compared with other species of the subgenus, representing the first hypogean rove beetle from mainland Portugal. A comparison between Domene lusitanica n. sp. and the other species of the Iberian endemic subgenus Lathromene is made using diagnostic characters. An identification key for the males of Lathr...

We describe a new mantellid frog of the subfamily Mantellinae from the karstic Bemaraha Plateau, western Madagascar. The new species belongs to the genus Gephyromantis, subgenus Phylacomantis, which previously included Gephyromantis azzurrae, Gephyromantis corvus and Gephyromantis pseudoasper. Gephyromantis atsingysp. n. has a snout-vent length of 35-43 mm and is a scansorial frog living among ...
