Sulfur (34S/32S) isotope composition of gypsum and implications for deep cave formation on the Nullarbor Plain, Australia
Matej Lipar, Mateja Ferk, Sonja Lojen, and Milo Barham

  • Gypsum appears in caves on the Nullarbor Plain
  • δ34S of gypsum shows relatively high positive δ34S values
  • Cave sulphate minerals are evaporates


A review of fractals in karst
Eulogio Pardo-Igúzquiza, Peter A. Dowd, Juan J. Durán, and Pedro Robledo-Ardila

  • Scale-invariance, self-similarity and universality are ubiquitous in karst
  • Fractal can be found in the exokarst and the endokarst
  • Fractals are also found in karst hydrogeology
  • Hypotheses and conjectures about the origin of such behavior are proposed


ISOLUTION 1.0: an ISOtope evoLUTION model describing the stable oxygen (δ18O) and carbon (δ13C) isotope values of speleothems
Michael Deininger and Denis Scholz

  • A speleothem proxy system model for stable oxygen and carbon isotopes
  • Modeling of disequilibrium isotope fractionation processes in speleothems
  • Modeling of stable oxygen and carbon isotopes in dependence on cave parameters


Fifty years of cave arthropod sampling: techniques and best practices
J. Judson Wynne, Francis G. Howarth, Stefan Sommer, and Brett G. Dickson

  • 110 papers examined (from 1967 - 2018) to explore how cave-dwelling invertebrates were sampled
  • A summary of techniques most commonly applied and appropriateness of these techniques is provided
  • Nearly one-half of the studies applied systematic techniques
  • Few papers provided enough information to repeat the study
  • Inconsistencies in sampling techniques nomenclature observed
