“…(Lindberg et al, 2002), Chamobates borealis and Tectocepheus velatus as heavily affected by drought, while Disshorina ornata is characterized as drought tolerant (Taylor and Wolters, 2005). Species with sexual reproduction and narrow habitat preference are more tolerant to drought (Lindberg and Bengtsson, 2005) compared to species with greater size and living in the soil surface or forest litter (Lindberg et al, 2002) and those Oribatids which slowly colonized the offered litter in a litter colonization experiment (Taylor and Wolters 2005). The work of (Walter and Proctor, 1999, Taylor et al, 2002, Taylor and Wolters, 2005 states that adult individuals are able to tolerate a wide range of water content, but nymphs are quite susceptible to drought (Taylor and Wolters, 2005).…”

“…Moreover, oviposition of some species are connected to special fungi (Hågvar, 1998, Lindberg et al, 2002. Lindberg and Bengtsson (2005) described that there are differences among Oribatid groups in drought tolerance. Species with sexual reproduction and species with less prevalence have a better drought tolerance than generalists and parthenogenetics.…”

Abstract. This review discusses the connection between quantitative changes of environmental factors and oribatid communities. With the overview of available studies, it can be clearly explored how various characteristics of Oribatid communities are modified due to changes in moisture, temperature, heavy metal concentration, organic matter content and level of disturbance. The most important question concerning the application of Oribatids as indicators is to clarify what kind of information content does natural Oribatid coenological patterns possess from the aspect of bioindication. Most of the variables listed above can be directly measured, since rapid methods are available to quantify parameters of the soil. Responses of Oribatids are worth to study in a more complex approach. Even now we have an expansive knowledge on how communities change due to modifications of different factors. These pieces of information necessitate the elaboration of such methods which render Oribatid communities suitable for the task to prognosticate what extent the given site can be considered near-natural or degraded, based on the Oribatid composition of a single sample taken from the given area. Answering this problem needs extensive and coordinated work.

“…able to reduce evaporative water loss) because of their sclerotized integument (Madge, 1964;Vannier, 1987;Wauthy & Vannier, 1988). Despite their resistance to desiccation, some fi eld experiments show that oribatid populations decline in abundance during periods of drought (Lindberg & Bengtsson, 2005;Tsiafouli et al, 2005); whereas other studies suggest that oribatid mites are less responsive to drought than other groups of mesofauna (Andresen et al, 2011;Vestergård et al, 2015). The outcome of such studies is likely to depend on the actual drought stress occurring in the soil.…”

Abstract. We studied the water balance, body fl uid osmolality and survival of the oribatid mite, Pergalumna nervosa, when exposed to drought in fi eld and laboratory experiments. In a replicated fi eld experiment we artifi cially lowered the soil water content by putting roofs over selected plots, which reduced soil water potential to levels well below the permanent wilting percentage for plants (i.e. below -1.5 MPa). Even though a slight decrease in the abundance of P. nervosa (only found in the 0-5 cm soil layer) was recorded during the most severe drought stress (ca. -3.5 MPa), the majority of adult mites clearly survived these conditions for 3 weeks in the fi eld without migrating to deeper soil layers. Exposing fi eld collected adults in laboratory experiments simulating even more severe drought conditions revealed that P. nervosa can survive several weeks of gradually increasing drought stress (down to -7 MPa) with moderate water loss. The osmolality of body fl uids increased as dehydration progressed, but apparently as a result of simple up-concentration of solutes and not the de novo synthesis of protective osmolytes. We compare and discuss these results in the light of what is known about other arthropods.

“…Similarly, Solida et al (2015) found that moister, more continental and relatively undisturbed woodlands with a closed canopy and high humus quality sustained a more complex microarthropod community, whereas more disturbed and xeric Mediterranean woodlands showed lower values of all investigated biodiversity parameters due to water limitation. Indeed, several studies have highlighted the strong influence of microclimate on oribatid (Irmler, 2004) and collembolan communities (Lindberg and Bengtsson, 2005;Makkonen et al, 2011;Petersen, 2011;Salmon et al, 2006). Drought periods also represent an important limitation factor for enchytraeid populations, which tend to be smaller during summer, with negative implications for decomposition rates (Nurminen, 1967).…”
