The structure of spider communities in limestone quarry environments
In Britain, upland spider communities can be found west of the Tees–Exe line between 300–1300 m where the physical conditions are often harsh due to an extremely variable climate, steep unstable slopes and thin soils (Ratcliffe, 1977). These communities often contain species which are common at lower altitudes and are characterized by the dominance of the Linyphiidae (Downie et al., 1995). Spid...
متن کاملApplication of Restoration Ecology Principles to the Practice of Limestone Quarry Rehabilitation in Lebanon
Restoration ecology is an emerging science dealing with applied ecology and aiming at “helping nature to recreate itself”. This comprehensive paper presents the findings and main results related to the analysis of natural vegetation dynamics on abandoned limestone quarries in Mediterranean environment. It aims to answer three basic questions: where, when and how should intervention by ecologica...
متن کاملDeterministic Deconvolution of Ground‐Penetrating‐Radar Data at a Limestone Quarry
A 30 m by 30 m two-dimensional grid was designed on a flat bench behind a quarry face of predominantly limestone with thin shale layers located at a Bonner Springs, Kansas site to test the utility of ground-penetrating radar (GPR) for stratigraphic studies. GPR data were collected along seven lines parallel to the quarry face and seven lines perpendicular to the quarry face, each separated by 5...
متن کاملFactors Controlling the Formation of Fossiliferous Beds in the Devonian Columbus Limestone at Marblehead Quarry, Marblehead, Ohio
This study uses taphonomic, sedimentologic, and stratigraphic evidence from fossiliferous beds in Marblehead Quarry to review two hypotheses: 1) that the fossiliferous beds at Marblehead Quarry represent a series of in situ paleocommunities, and 2) whether fossiliferous concentrations in carbonate environments are primarily caused by periods of low net sedimentation. The fossiliferous beds of M...
متن کاملPrize quarry
dogfish and a total allowable catch of zero for 2010. Scientists had recommended a zero catch for this year as studies suggest the northeast Atlantic population is on the verge of collapse. Catches for cod outside the North Sea, hake, monkfish, sole and whiting have also been agreed at levels higher than those recommended by EU advisors. The Bay of Biscay anchovy fishery is to remain closed but...
