The functional ecology of Eastern Rûens Shale Renosterveld
… degradation on litter decomposition rates and Springtail (Collembola) community dynamics, respectively. Finally, in Chapter 5, I constructed three high-resolution plant-pollinator networks from sites with distinct land-use histories and with different above-ground vegetation communities. The …

Belowground success: Collembola as indicators of restoration progress following active and passive restoration
… soil fauna. This study assessed Collembola (springtail) communities between active and passive restoration sites in comparison to invaded, non-restored sites as reference sites. Sampling was conducted during winter (2020) and winter and spring (2021) to consider the seasonal effects. From a …

Beurteilung der Lebensraumfunktion von Böden anhand von Bodenwerten und ökotoxikologischen Labortests
… of ecotoxicological tests with earthworms and springtails as an example. First, dose-response tests were performed with zinc nitrate and tributyltin oxide in nine natural soils and OECD artificial soil and second, six contaminated soils from different legacy sites were assessed. Earthworm and …

The influence of vicariance and dispersal on the diversification and evolution of springtails (collembola)
… and maintenance of biodiversity in springtails (Collembola). This class of tiny, wingless insect-like hexapods includes some of the most abundant (and perhaps, most diverse) arthropods on earth. They have colonized, diversified, and adapted to nearly every terrestrial habitat from …

Assessment of Petroleum Hydrocarbon Contamination In Terrestrial Ecosystems Using Conventional and Novel Approaches
… and identify molecular biomarkers in a model springtail species, Folsomia candida, suitable for high-throughput toxicity testing. Weathered PHC-contaminated soils from a Northwestern Canadian site were found to be non-toxic to native soil invertebrate and plant species despite exceeding …

Population genetic structure of Antarctic springtails (Collembola) and New Zealand damselflies (Odonata)
… (mt) DNA haplotypes for the Antarctic springtail Gomphiocephalus hodgsoni (Collembola) in Taylor Valley, southern Victoria Land. The observed distribution was congruent with a hypothesis of multiple refugia during the Pleistocene glaciations and a barrier to gene flow by a glacial lake. …

PLANT AND ARTHROPOD COMMUNITIES OF ALPINE ICE-RELATED LANDFORMS: ECOLOGICAL AND BIOGEOGRAPHIC IMPORTANCE
… communities. Study 3.3 focuses on glacial springtails and regards the description of a new species of ice-dwelling springtail from Calderone glacier (3.3, Valle et al. 2021). Studies 3.4-3.5 (Valle et al. 2020, Ornaghi et al. submitted) analyse the efficacy of cryophilic ground beetles …

The resilience of Polar Collembola to climate change
… than any other on earth. Globally, Collembola (springtails) are among the most abundant and widely-distributed arthropods and are key components of species-poor polar ecosystems. Understanding the resilience of polar collembola to climate change is therefore an urgent research priority. Here we …
