Freezing: how do water mites (Acari: Hydrachnidia) survive exposure to sub-zero temperatures?

Exp Appl Acarol 2021 Jul 21;84(3):565-583. Epub 2021 Jun 21.

Institute of Marine and Environmental Sciences, Center of Molecular Biology and Biotechnology, University of Szczecin, Szczecin, Poland.

Until now, very little is known about the ability of adult and deutonymph water mites (Acari, Hydrachnidia) to survive in sub-zero temperatures. Information concerns mainly water mites from vernal astatic waters, and the knowledge has never been experimentally verified. To determine the sensitivity of water mites to freezing, experiments were conducted on (1) the impact of acclimatization, (2) temperature, and (3) duration of freezing on survival, (4) the survival rate of water mites from various types of water bodies, and (5) the survival rate of water mites from different climatic zones.

Hygrobates salamandrarum Goldschmidt, Gerecke and Alberti, 2002 (Acari, Hydrachnidia, Hygrobatidae) is the first-known water mite parasitizing adult newts. After its description, three further species of newt-parasitizing mites were described and the subgenus Lurchibates Goldschmidt and Fu, 2011 was proposed for the group, now containing four newt-parasitizing mites. Until now, each water mite species parasitizes a different newt species (Table 1), suggesting possible mite-newt co-speciation. Read More

Parasitism Risk and Infection Alter Host Dispersal.

Am Nat 2020 08 10;196(2):119-131. Epub 2020 Jun 10.

Dispersal determines the spatial dynamics of host-parasite assemblages, particularly during invasions and disease epidemics. The risk of parasitism may create an incentive for dispersal, but infection is expected to reduce dispersal ability, which may alter the host's dispersal response to biotic stressors, including population density. We measured the dispersal of a semiaquatic insect () in aquatic mesocosms in which we manipulated the presence of ectoparasitic Hydrachnidia mites and infected conspecifics. Read More

Molecular Correlation between Larval, Deutonymph and Adult Stages of the Water Mite .

Life (Basel) 2020 Jul 9;10(7). Epub 2020 Jul 9.

Museo Nacional de Ciencias Naturales, CSIC. C/José Gutiérrez Abascal, 2, 28006 Madrid, Spain.

The systematics of many groups of organisms has been based on the adult stage. Morphological transformations that occur during development from the embryonic to the adult stage make it difficult (or impossible) to identify a juvenile (larval) stage in some species. Hydrachnidia (Acari, Actinotrichida, which inhabit mainly continental waters) are characterized by three main active stages-larval, deutonymph and adult-with intermediate dormant stages. Read More

Is the spatial distribution of lentic water mite assemblages (Acari: Hydrachnidia) governed by prey availability?

Exp Appl Acarol 2019 Apr 14;77(4):487-510. Epub 2019 May 14.

Department of Biology, Faculty of Science, University of Zagreb, Rooseveltov trg 6, 10000, Zagreb, Croatia.

Predation is a biotic interaction that links water mites to different taxonomic groups of benthic invertebrates. Diptera larvae (Chironomidae) and microcrustaceans (Cladocera, Copepoda, Ostracoda) are known to be the most commonly preferred prey by water mites. Although these predatory interactions are known from observations and ex situ investigations, the distribution patterns and co-occurrence of water mites and their prey in littoral lentic habitats have been poorly studied.
