Regionally widespread parasitic water mites have relatively broad host species ranges
Canadian Journal of Zoology
Certain parasite species have free-living stages, so habitat range may influence host-species range. We tested whether regional occurrence and habitat use of parasitic water mites were related to their host-species range. We collected 7445 Arrenurus Dugès, 1834 mites from 7107 coenagrionid damselflies, representing 11 host species from 13 sites in southeastern Ontario and southwestern Quebec. Because larval water mites are difficult to identify morphologically to species, we chose to amplify the barcode fragment of cytochrome oxidase subunit I to explore host-species ranges. Fifteen operational taxonomic units or clades were identified based on the amplification from 217 larval mites. The Arrenurus clades that were present in both bog and marsh habitats had a broader host-species range than clades found only in marshes (the comparison with one clade found only in bogs lacked statistical power). As predicted, host-species range increased with the regional occurrence of an Arrenurus clade. Additionally, the most commonly barcoded species also have high host-species ranges. This result could be because species with broader host-species ranges are more common and were more likely to be sampled and barcoded (an explanation we favor), or due to sampling bias. Although this is the first study exploring whether habitat range affects host-species range, further investigation is needed to tease apart which habitat factors influence host-species ranges the most.

Baltic island of Gotland, and two from Norway near the Arctic Circle-were investigated for invertebrates by means of pitfall traps and by hand-picking. 1,765 Gamasina mites were found and determined to species and developmental stages. 37 species in 9 families were identified. One species alone, Parasitus loricatus, made up 75.0% of the total number of mites. Six other species, viz. Poecilochirus carabi, Vulgarogamasus oudemansi, Pergamasus robustus, Vulgarogamasus remberti, Cyrtolaelaps mucro natus and Vulgarogamasus kraepelini made up another 20.2% of the total number of mites. The numbers of individuals and species in this investigation exceeded by far those usually reported from investigations of caves in Europe, probably due to our use of pitfall traps. RESUME : Six grottes de Scandinavie (Suede : 2 ; lles de la mer Baltique, Gotland : 2; Norvege: 2 proches du Cercle polaire) sont prospectees par piegeage et recolte des invertebres. 1765 gamasides ont ete recoltes et determines. Ils appartiennent a 37 especes de 9 familles differentes. Parasitus loricatus represente plus de 75% des individus et six autres especes 20% (Poecilochirus carabi, Vulgarogamasus oudemansi, V remberti, V kraepelini, Pergamasus robustus et Cyrtolaelaps mucronatus). Les resultats montrent un nombre anormalement eleve d'individus et d'especes par rapport aux autres prospections de grottes en Europe: il s'agit probablement de la consequence de !'utilisation de pieges d'interception.
Molecular phylogenetics and evolution, 2016
With nearly 6000 named species, water mites (Hydrachnidiae) represent the largest group of arachnids to have invaded and extensively diversified in freshwater habitats. Water mites together with three other lineages (the terrestrial Erythraiae and Trombidiae, and aquatic Stygothrombiae), make up the hyporder Parasitengonina, which is characterized by having parasitic larvae and predatory nymphs and adults. Relationships between the Hydrachnidiae and other members of the Parasitengonina are unclear, as are relationships among the major lineages of water mites. Monophyly of water mites has been asserted, with the possible exception of the morphologically distinctive Hydrovolzioidea. Here we infer the phylogeny of water mites using multiple molecular markers and including representatives of all superfamilies of Hydrachnidiae and of almost all other Parasitengonina. Our results support a monophyletic Parasitengonina including Trombidiae, Stygothrombiae, and Hydrachnidiae. A monophyletic...

In comparison to Central Europe, the knowledge about water mites inhabiting the natural lakes of southern Europe is scarce. This is a first study focusing on the water mite species composition and zonation in a large Mediterranean lake, i.e. ancient Lake Skadar basin, and identifying the role of physical and chemical water parameters in their distribution. The Hydrachnidia community of Lake Skadar is composed of 53 species. The most diverse water mite assemblages were found in the littoral zone and in the sublacustrine springs. Our study revealed that water mites were most abundant in the deeper, open part of Lake Skadar. Typically sublacustrine species dominated in all zones and habitats of Lake Skadar. The rheobiontic and rheophilic species also had a substantial share, mainly in sublacustrine springs, but also in the open lake area. The unique feature of the Lake Skadar water mite community was an absence of many species typical for the vernal astatic waters and for the shallow phytolittoral zone, even if such habitats were present. We conclude that the structure of the water mite communities in Lake Skadar are associated with particular zones (sublacustrine springs, littoral, open lake area) of the lake and with local environmental conditions, predominantly temperature.
