The Editorial is confined to a discussion of production methods for Cave and Karst Science. Digital techniques are used to produce the camera-ready hard copy, which is supplied, lacking only its photographic illustrations, to the printer. Line illustrations are inserted directly into the DTP files and printed as part of the camera-ready copy. In contrast, photographic illustrations are "dropped into" the camera-ready copy by the printing company. Authors are asked to provide photographic illustrations only if they are of sufficiently high quality to remain interesting and informative after printing. Secondly, if authors wish to provide photographic images digitally, they should ensure that they are properly balanced and of sufficiently high resolution. However, especially in the case of potential cover photos, unless high-quality, high-resolution photo-files are available, good hard copies (print or transparency) are preferred. Otherwise, the various guidelines included inside the front cover continue to apply. Recommendations regarding text on illustrations large enough to allow reduction remain particularly important. Large landscape format figures that need rotating through 90 degrees to present them sideways on a portrait format page are to be avoided - they will inevitably be reduced to fit across the page to be part of the flow of the article, but problems arise if the text is too small to be read if this is done.

Speleogenesis along sub-vertical joints:
A model of plateau karst shaft development:
A cast study: the Dolny Vrch Plateau (Slovak Republic)
Vol 29 (1) pp 5 - 12

Abstract: Speleogenesis of narrow and relatively deep karst shafts (avens) was studied in the Slovak part of the Dolny Vrch Plateau (the Slovak Karst Biosphere Reserve, SE Slovakia). Most of the 211 shafts and shaft-related depressions located on the plateau have similar characteristics and no shaft has a known accessible connection to an active horizontal cave system. Dominant tectonic fractures are sub-vertical (sloping 70 - 90 degrees) in most of the shafts. Several microforms, e.g. scallop-like forms, wall troughs or networks of protruding veins, evidence of the main speleogentic processes.
Water film dissolution extends the fractures, usually at the base of the epikarstic zone (Klimchouck, 1995), while the scallop-like forms develop. Then corrosive and erosive action of dripping water takes place and the wall troughs develop downwards - the shaft develops progressively now. Increased carbon dioxide concentration makes the solutions more aggressive and enables the processes working on the shaft bottoms. Water film action and selective condensation corrosion are responsible for upward shaft development. Later, shafts open to the surface, interacting with the effects of surface denudation.

Karst and caves of Madagascar

Vol 29 (1) pp 13 - 20

Abstract: Madagascar contains some major areas of cavernous karst close to its west coast. Ankarana has the largest and longest caves. Bemaraha and Namoroka have the best of the dramatic and almost impenetrable tsingy landscapes - small-scale versions of pinnacle karst. The karst areas are reviewed from north to south, and new data are included on caves and landforms in the smaller karst blocks around Majunga.

A history of cave exploration in the Northern Pennines, United Kingdom, from 1838 until 1895

Vol 29 (1) pp 21 - 32

Abstract: The trends of cave exploration in the Northern Pennines during the second half of the Nineteenth Century responded to the arrival of the railway at the western periphery of the limestone country. This ease of travel for the working classes encouraged access to the show caves. It also enabled the more affluent residents of the Lancashire and Yorkshire conurbations to explore the caves, whereas the relative contribution of the local landowners became less.

Invertebrate fauna of Manx caves and mines:
a preliminary survey
Vol 29 (1) pp 33 - 37

Abstract: The Isle of Man was heavily glaciated and thus all of its invertebrate fauna is the result of post-Pleistocene recolonization. Accordingly, it presents the opportunity to observe an early stage of the active invasion and colonization of hypogean habitats on a maritime temperate island by epigean species. It also has many sea caves, some of which have diverse invertebrate communities. This paper reports the results of a preliminary speleo-biological survey of the island, which revealed an unexpectedly rich and diverse hypogean fauna.

Gypsum karst near Sivas, Turkey
Vol 29 (1) pp 39 - 44

Abstract: A large area of spectacular karst stands on thick Miocene gypsum in central Turkey. Numerous dolines coalesce into fine polygonal karst. Large collapse dolines and marginal poljes are also notable features. Few caves are known, but some sinkholes, stream passages and foot caves await complete exploration.
