“…However, virtually all collembolans have an affinity for areas marginal to aquatic habitats because of their requirement of high humidity. A few species are restricted to aquatic habitats and exhibit a high degree of specialisation for an aquatic existence (Heckman, 2001). Diversity: There are ca 9000 described species world wide (Resh & Carde, 2003).…”

There is a need for monitoring the status and trends of freshwater biodiversity in order to quantify the impacts of human actions on freshwater systems and to improve freshwater biodiversity conservation. Current projects carrying assessment of freshwater biodiversity focus mainly on leading-better-known groups such as fish, or identify keystone species and/or endemic freshwater systems for conservation purposes. Our purpose is to complete these existing projects by providing quantitative estimates of species number for all freshwater groups on each continent and/or major eco-regions. This article present the results of the first implementation phase carried out from

“…Soil microarthropods were extracted using a modified Tullgren extractor (van Straalen & Rijninks ) over a 4 days period. Springtails (Collembola) were identified to species level following various keys, as there is no comprehensive identification key for the Falkland Islands (Salmon ; Heckman ; Fjellberg ). Mites (Acari) were grouped into major orders: Astigmata‐Prostigmata, Oribatida and Mesostigmata, and only Oribatida were further identified to family or genus level following Weigmann ().…”

Dwarf shrub and grass vegetation resistant to long‐term experimental warming while microarthropod abundance declines on the Falkland Islands

et al. 2017

Dwarf shrubs are a dominant plant type across many regions of the Earth and have hence a large impact on carbon and nutrient cycling rates. Climate change impacts on dwarf shrubs have been extensively studied in the Northern Hemisphere, and there appears to be large variability in response between ecosystem types and regions. In the Southern Hemisphere, less data are available despite dwarf shrub vegetation being a dominant feature of southern South America and mountainous regions of the Southern Hemisphere. Here, we present the response of an Empetrum rubrum dwarf shrub and a Poa grass community to 12 years of experimental climate manipulation achieved using open top chambers on the Falkland Islands, a cold temperate island group in the South Atlantic. The dwarf shrub and grass vegetation did not change significantly in cover, biomass or species richness over the 12 years period in response to climate warming scenarios of up to 1°C reflecting annual warming levels predicted in this region for the coming decades. The soil microarthropod community, however, responded with declines in abundance (37%) under warming conditions in the grass community, but no such changes were observed in the dwarf shrub community. Overall, our data indicate that dwarf shrub communities are resistant to the levels of climate warming predicted over the coming decades in the southern South America region and will, therefore, remain a dominant driver of local ecosystem properties.

“…We initially identified microarthropods down to the family level, and when possible, we further determined them to the species level using identification keys and species descriptions. To identify families of mites, we used Krantz & Walter, 2009, for Collembola, Bernava & Palacios Vargas, 2000Heckman, 2001;Bellinger et al, 2024 andAmendt et al, 2010, for immature insects. Oribatid mites were identified at the species level by using keys and scientific descriptions (Hammer, 1958(Hammer, , 1961(Hammer, , 1962a(Hammer, , 1962bBalogh & Csiszár, 1963;Balogh & Balogh, 1988, 1990.…”

The attractive effect of dung on coprophagous beetle communities and their role in dung degradation are well‐known phenomena. However, little research has been conducted on the recruitment capacity of this substrate for other arthropods, especially those inhabiting the soil. With the aim of beginning to recognize general patterns in these relationships, the influence of the structure and origin of dung from invasive exotic mammals on the recruitment of microarthropods was investigated in two meadows within Nahuel Huapi National Park in southwestern Argentina. Abundance, richness and diversity of microarthropod communities collected on invasive mammal dung were studied. A total of 2478 microarthropods were collected and 52 species were identified. Recruitment of microarthropods on dung of two invasive coprophagic herbivores, the rabbit, Oryctolagus cuniculus and the hare, Lepus europaeus, were compared with two invasive non‐coprophagic mammals, one herbivorous, the red deer, Cervus elaphus and one omnivorous, the wild boar, Sus scrofa. Pellets of S. scrofa showed the highest microarthropod abundance and richness while diversity was greatest on pellets of C. elaphus. Pygmephorid and oribatid mites and springtails were the most abundant. Liposcelis psocopterans and oribatid mites were more abundant on S. scrofa dung. Low similarity was observed when comparing dung of invasive mammals from different sites revealing spatial variability regarding species composition. Based on its more diverse diet, we conclude that S. scrofa dung exerts a strong influence on microarthropod communities by recruiting a greater number of individuals and species than the dung of the remaining invasive mammals.
