We examined community diversity, structure and carbon footprint of nematode food web along a chronosequence of T. Sinensis reforestation on degraded Karst. In general, after the reforestation: a serious of diversity parameters and community indices (Shannon-Weinier index (H'), structure index (SI), etc.) were elevated; biomass ratio of fungivores to bacterivores (FFC/BFC), and fungi to bacteria...

A frequency domain tomographic inversion was developed to estimate frequency dependent energy attenuation by using prestack depth migration common image gathers (CIGs). The frequency dependent attenuation is estimated from the centroid frequency difference for reflections in CIGs. Migration stretch and ghost effects are taken into account to get correct measurements of frequency. This method ma...

Two conventional onsite sewage treatment and disposal systems (OSTDSs) at Manatee Springs State Park, Florida, USA, were studied to assess their impact on groundwater quality in a shallow karst environment. Sulfur hexafluoride (SF6) and fluorescein were used as tracers to establish connections between the drainfields and monitoring wells. Elevated nutrients were found in all wells where signifi...

A new species of lowland karst dwelling Cnemaspis Strauch 1887, C. grismeri sp. nov. is described from the southeastern base of the Banjaran Bintang in northern Peninsular Malaysia. It is differentiated from its congeners by a unique combination of characters including size, coloration and scalation. Cnemapis grismeri sp. nov. is most closely related to C. mcguirei, an upland species endemic to...

Enhanced indoor radon levels are frequently found in the western part of the Swiss Jura mountains, a karst region. The activity in the limestone bedrock is low ( 20 Bq/kg). In the thin soil overburden the =Ra activity concentration is 2 to 3 times higher than in soil samples from the Swiss Plateau but on the average still below 100 Bq/kg. It is supposed that the radon problem in this region is ...

We describe a new species of gekkonid lizard, Gekko carusadensis, from low elevation, disturbed and secondary-growth forest in east-central Luzon Island, Philippines. Numerous features of its external morphology distinguish it from other congeners, including the presence of a distinct color pattern, body size, and a unique combination of scale counts. The new species has been found on karst out...

Karst aquifers have a high degree of heterogeneity and anisotropy in their geologic and hydrogeologic properties which makes predicting their behavior difficult. This paper evaluates the application of the Equivalent Porous Media (EPM) approach to simulate groundwater hydraulics and contaminant transport in karst aquifers using an example from the North Coast limestone aquifer system in Puerto ...
