In this article, the authors examined year-long hourly temperature profiles at sites in lava in the Canary Islands and limestone in Slovenia and found that the temperature extremes were much less pronounced in MSS sites.Abstract:
Within the soil matrix and underlying rock, cracks and fissures and other air-filled spaces between rocks, sometimes called the milieu souterrain superficiel (MSS), are present in a variety of geological contexts. We examined year-long hourly temperature profiles at sites in lava in the Canary Islands and limestone in Slovenia. All sites had species that show morphological adaptations usually associated with cave-dwelling organisms, including elongated appendages and reduced eyes and pigment. MSS sites were studied at depths between 10 and 70 cm and showed strong seasonality, and most had a discernible diurnal cycle as well. The most striking difference from surface habitats was that the temperature extremes were much less pronounced in MSS sites. Temperature variability was not correlated with troglobiotic species richness. The presence of species with similar morphologies to those found in caves indicates that selective pressures are similar in cave and shallow subterranean habitats.read more

Finding answers in the dark: caves as models in ecology fifty years after Poulson and White
TL;DR: The use of semi-isolated habitats such as oceanic islands, lakes and mountain summits as model systems has played a crucial role in the development of evolutionary and ecological theory as mentioned in this paper.

Convergence and divergence in the subterranean realm: a reassessment
Tanja Pipan,David C. Culver +1 more
TL;DR: A review of data on patterns of troglomorphy suggests that the absence of light, rather than resource level and environmental cyclicity, is the important selective factor, and that other forces are at work, including competition and differences in the age of lineages in subterranean environments.

The “Alluvial Mesovoid Shallow Substratum”, a New Subterranean Habitat
Vicente M. Ortuño,José D. Gilgado,Alberto Jiménez-Valverde,Alberto Jiménez-Valverde,Alberto Sendra,Gonzalo Pérez-Suárez,Juan J. Herrero-Borgoñón +6 more
TL;DR: It is possible that the “alluvial MSS” may be found in other areas of the world with strongly seasonal climatic regimes, and could play an important role as a biogeographic corridor and as a refuge from climatic changes.

Diversity of energy fluxes and interactions between arthropod communities: from Soil to Cave
TL;DR: For the analysis of arthropod communities, using the notion of functional groups, the existence of links between two components, hypogean species, and endegean-epigean species are shown, defining an ecotone along the vertical gradient ‘soil to cave’.
