%T Monitoring the population of the linyphid spider Porrhomma rosenhaueri (L. Koch, 1872) (Araneae: Linyphiidae) in Lesser Garth Cave, Cardiff, UK
%A Julian CARTER, Adrian FOWLES, Catalena ANGELE
%X The cave dwelling spider Porrhomma rosenhaueri (L. Koch) is unique to the British fauna as it is considered to be the only species of troglobiont spider present. This spider has a very limited distribution in the UK and is known only from two cave sites, both of which are in South Wales: Ogof y Ci near Merthyr Tydfil and Lesser Garth Cave near Cardiff. Monitoring populations of cavernicolous species is very difficult to achieve and the aim of this survey was to set up a Common Standards Monitoring (CSM) protocol that would allow meaningful data to be compiled as to the size and viability of the spider population in the Lesser Garth Cave complex. A defined transect of the main passage in the cave was surveyed, carefully searching the accessible parts of the passage for both live spiders and webs in good condition but with no obvious spider present. The first visit was made in September 2009 and 17 live spiders were recorded, removing one to confirm identification. During a follow up survey in December 2009 only 6 live spiders were recorded. Possible reasons for this are discussed in this paper. The overall impression is that, despite living next to an active quarry, the spider Porrhomma rosenhaueri is still well-established in the Lesser Garth Cave. The cave itself has a rich diversity of cave associated species and is thus an important site for speleobiology in the UK

%T Derbyshire pipe veins - deep-seated speleogenesis
%A Trevor D FORD
%X In the Derbyshire lead-mining field pipe veins are those mineral deposits developed along the bedding or along other nearly horizontal discontinuities in the Carboniferous Limestone. The pipes commonly show evidence of pre-mineralization caverns developed by dissolution in slow-moving hydrothermal waters derived from adjacent basins under changing tectonic stress regimes, aided by seismic pumping from repeated fault movements. Other pipes were developed at the base of regionally dolomitized limestones, again preceding mineralization. In late Carboniferous times the caverns were filled or lined with the hydrothermal Pb-Zn-F-Ba-Ca mineral suite. In some pipes post-mineralization dissolution has led to partial collapse of the mineral linings. Evidence of vadose cave development is largely limited to the Blue John pipes of Treak Cliff at Castleton, but in the Winster and Matlock area there are pipes with fills of clastic sediment largely of glacial outwash character.
