“…Even at the small spatial scale of meiofauna, a bare pneumatophore seems devoid of suitable habitat; a previous study (Gwyther 2000) found that a few mites were the sole meiofauna on unfouled pneumatophores. Bartsch (1989) recorded mites among barnacles and algae in several geographical regions, but she considered mites to be very rare in silty flats. At our study site, mites made up only 0.2% of sediment meiofauna but represented 91% of the meiofauna on barnacle-covered pneumatophores (Gwyther 2000).…”

The size and pace of change in meiofaunal assemblages suggest that meiofauna make excellent subjects for testing theories about how ecological communities change. A field experiment was performed in which the abundance and composition of epibionts and meiofauna on natural, transplanted and mimic pneumatophores were monitored over a 47 wk period. Meiofaunal density increased with growth of algal epibionts, both reaching maximum values after 24 wk, at the end of winter. At this time the assemblages from the 3 substrata were similar, although the combined abundances of meiofauna on transplants and mimics were only 28% of the average on natural pneumatophores. Meiofaunal abundance on all substrata decreased rapidly during spring as algal cover declined due to desiccation. Twenty-three species of nematode were recorded from mimics compared with 8 and 7 from transplants and pneumatophores, respectively. A temporal sequence of feeding groups occurred in the order of epigrowth feeders, deposit feeders, and omnivore/predators, with the latter 2 adding to rather than replacing earlier trophic groups. Scavengers were found only on natural pneumatophores. The turnover rates of nematode species between all census times were similar, peaking at 63%, but there was no trend in the turnover rates with time. We conclude that mimics are more suitable than transplanted pneumatophores for colonisation studies because of their greater persistence and more easily standardised surface area. Moreover, the composition of colonising assemblages on them closely resembled assemblages on natural pneumatophores at the time of peak meiofaunal abundance.

“…The mites in the sea, the halacarid mites, are expected to have evolved from aquatic or semiaquatic prostigmatid ancestors which colonized the sea shores. The taxon most likely exists since the Pre-Mesozoic or Mesozoic (Bartsch 1982(Bartsch , 1989a(Bartsch , 1996. Freshwater halacarids are polyphyletic, descendants of marine or brackish water ancestors (Petrova, 1974;Bartsch 1982Bartsch , 1996.…”

Halacarid mites have successfully invaded the sea and approximately 56 species colonized the freshwater. Invasion from the sea into continental waters probably started in the Mesozoic or PreMesozoic and went on in the following epochs. The number of genera (14) and species (34) recorded from the Palaearctic is remarkably higher than that of other geographical regions. These numbers do not imply that the Palaearctic is a centre of origin, they reflect the sampling activity rather than reliable data on diversity.

“…Hence, in general, the halacarid mite fauna of the Svalbard region can be described as rather specialized and mainly cryophilic. The nonswimming halacarid mites have very limited dispersion and reproductive capacities (Bartsch 1989(Bartsch , 2008. Nevertheless, we may attribute this conclusion to our still insufficient knowledge.…”

“…Whereas freshwater forms are rather rare, euryhaline species are numerous. The family Halacaridae includes both phytophagous (mostly algophagous) and predatory forms (Bartsch 1989(Bartsch , 2008. Although a significant amount of data on freshwater mites of the Low Arctic is available (Viets 1928;Sokolov 1952;Habeeb 1957;Bartsch 1978Bartsch , 2011Semenchenko et al 2010;Gerecke 2015), information on the faunas of the High Arctic areas is scarce (Bartsch 1978;Danks 1981;Gerecke 2015).…”

This paper presents the first results of a study on the aquatic mites (Acari) from the inland water bodies of West Spitsbergen, Svalbard. Six mite species have been found: namely, the oribatids Camisia foveolata Hammer, 1955 and Ameronothrus lineatus (Thorell, 1871); the gamasid mite Halolaelaps sp.; as well as the halacarids Halacarellus sp., Isobactrus levis (Viets, 1927) and Rhombognathides spinipes (Viets, 1933). The latter two species are new to the fauna of Svalbard. No true freshwater mites (Hydrachnidia) have been identified. A preliminary comparison of the inland aquatic acarofauna of Svalbard with the fauna of other Arctic regions has been conducted. The entire halacarid mite fauna of Svalbard (13 species), including both inland water species and true marine ones from the surrounding seas, can be characterized as rather regionally specialized and mainly cryophilic.
