A Unique Small-Scale Microclimatic Gradient In A Temperate Karst Harbours Exceptionally High Diversity Of Soil Collembola, Natália Raschmanová, Dana Miklisová, Ľubomír Kováč

The collapse doline of the Silická ľadnica Ice Cave, 351 m2 in area, is a unique phenomenon, a steep microclimate gradient in a low-altitude temperate karst in the Western Carpathian Mts, Slovakia, with a remarkable temperature decrease from the edge of karst plateau towards the doline bottom, which harbours perennial ice deposits. Collembola communities were studied in detail at seven sites along the 117.5 m long gradient slope during 2005–2007. An exceptionally high species richness of soil Collembola was observed, 129 species, which is about 91% of the total species richness generated by Chao1/ACE estimator. Species richness positively correlated …

The activity of enzymes associated with digestion can reflect food availability and feeding preferences of invertebrates in a particular habitat. Caves are mostly nutrient-poor habitats lacking primary production. In the present study the enzymatic activity of cellulases, trehalases and chitinases was measured in eight collembolan species differently associated with the cave environment: the troglobionts (obligate cave species) Pseudacherontides spelaeus and Protaphorura janosik; the eutroglophiles Ceratophysella denticulata, Folsomia candida and Heteromurus nitidus; the subtroglophiles Hypogastrura aequepilosa and Orthonychiurus rectopapillatus; and the trogloxene (not associated with caves) Megaphorura arctica. Qualitative enzymatic patterns and quantitative differences in species activity were …

Numerous studies investigate morphology in the context of habitat, and lizards have received particular attention. Substrate usage is often reflected in the morphology of characters associated with locomotion, and, as a result, claws have become well-studied ecomorphological traits linking the two. The Kimberley predator guild of Western Australia consists of 10 sympatric varanid species. The purpose of this study was to quantify claw size and shape in the guild using geometric morphometrics, and determine whether these features correlated with substrate use and habitat. Each species was assigned a Habitat/substrate group based on the substrate their claws interact with in their …
