The genus Galumna in Nepalese oribatid mite fauna, with notes on systematic placement of some species (Acari, Oribatida, Galumnidae)
2014
The oribatid mite genus Galumna (Oribatida, Galumnidae) is recorded for the first time in Nepal. A new species, Galumna tetraporosa sp. n., is described from soil of secondary mixed broadleaved forest. It is most similar morphologically to G. tokyoensis Aoki, 1966 and G. valida Aoki, 1994, however, it differs from both by the absence of interlamellar setae and the presence of two pairs of notogastral porose areas Aa. Galumna granalata Aoki, 1984 is redescribed on the basis of specimens from Nepal. Galumna floridae (Jacot, 1929) and G. hexagona Balogh, 1960 are transferred to the genus Notogalumna; G. mauritii Mahunka, 1978 is transferred to the genus Dimidiogalumna.
Kontrolētas degšanas ietekme uz augsnes bruņērču (Acari: Oribatida) sugu sabiedrībām un sukcesija divu gadu periodā priežu mētrājā, aizsargājamo aina…
2020
Mežu degšanai ir būtiska loma barības vielu apritē un bioloģiskajā daudzveidībā. Bruņērces (Acari: Oribatida) ir svarīgi organisko vielu noārdītāji. Kontrolēta dedzināšana var sniegt vērtīgu informāciju par post–pirogēnas sukcesijas procesu. Darba mērķis ir noskaidrot degšanas ietekmi uz augsnes bruņērču sabiedrībām, veģetāciju un augsnes parametriem priežu mētrājā un sukcesiju divu gadu periodā. Pēc degšanas konstatēts būtisks indivīdu blīvuma un daudzveidības samazinājums, bet divu gadu laikā tie būtiski palielinās. Apstiprināts, ka sugu sabiedrības pēc degšanas veido sugas, kam ir raksturīgs augsts indivīdu blīvums pirms traucējuma. Novērotas būtiskas veģetācijas un abiotisko faktoru (re…
Dispersal of microarthropods in forest soil
2001
Summary This experiment was a part of a research on the soil community in anthropogenous birch stands in Finland. In that study it was found that communities of Collembola are similar in birch stands of different origin (cultivated field or spruce forest), while the communities of Oribatida are essentially different. When compared to original spruce forest, the communities of both groups are different. Cultivation eliminates the populations of most microarthropod species, that have to disperse after reforestation from the surrounding areas. The aim of the experiment was to study the ambulatory dispersal of soil microarthropods. It was carried out in plastic boxes filled with an intact block…
<p class="HeadingRunIn"><strong>The genus <em>Uracrobates</em> (Acari, Oribatida, Mochlozetidae)</strong></p>
2015
Uracrobates (Parauracrobates) truncatus sp. nov. is proposed, based on specimens from soil in Nepal. Parauracrobates subgen. nov. is distinguishable from subgenus Uracrobates by the notogaster truncated posteriorly (versus conical). An identification key to known taxa in the genus Uracrobates is given.
The armoured mite fauna (Acari: Oribatida) from a long-term study in the Scots pine forest of the Northern Vidzeme Biosphere Reserve, Latvia
2014
In 1992-2012, a considerable amount of soil micro-arthropods has been collected annually as a part of a project of the National Long-Term Ecological Research Network of Latvia at the Mazsalaca Scots Pine forest sites of the North Vidzeme Biosphere Reserve. Until now, the data on oribatid species have not been published. This paper presents a list of oribatid species collected during 21 years of ongoing research in three pine stands of different age. The faunistic records refer to 84 species (including 17 species new to the fauna of Latvia), 1 subspecies, 1 form, 5 morphospecies and 18 unidentified taxa. The most dominant and most frequent oribatid species are Oppiella (Oppiella) nova, Tecto…
A new species of <em>Metapyroppia</em> Woolley, 1969 (Acari, Oribatida, Peloppiidae) from Nepal
2014
A new species of oribatid mites of the family Peloppiidae, Metapyroppia gigantea n. sp. , is described from Nepal. The genus Metapyroppia is recorded for the first time from the Oriental region. Metapyroppia gigantea n. sp. differs from the type species, Metapyroppia doratosa Woolley, 1969, by the absence of notogastral setae c 2 and c 3 , presence of pointed rostrum and the adanal lyrifissures distanced from the anal plates. The morphology of gnathosoma and legs are presented in detail for the first time for any member of this genus. urn:lsid:zoobank.org:pub:EEE741F4-4C86-4625-B3FD-48E1DDA1D2D3
Additions to the Nepalese oribatid mite fauna, with description of two new species (Acari, Oribatida)
2013
An annotated checklist of identified oribatid mite taxa from Nepal is provided. It includes 45 species/subspecies, 38 genera and 31 families; 34 species/subspecies are recorded for the first time in Nepal. Two new species, Eremaeus anichkini n. sp. (Eremaeidae) and Ghilarovizetes longiporosus n. sp. (Ceratozetidae), are described from soil and litter. An identification key to all known species of the genus Ghilarovizetes is given.urn:lsid:zoobank.org:pub:BE27D886-1294-4E55-AD0B-25CDFC663D71
Ptyctima (Acari, Oribatida) in various habitats in Finland
2010
The oribatid species of the taxon Ptyctima were studied in eight habitat types (four forests, three bogs, and one shore). Altogether 19 species were found. The highest number of species (15) was found in marsh forests in southern Finland, and the lowest number (3) in eutrophic fens in northern Finland. Atropacarus striculus was the most common and abundant species in Finland. It was found in each habitat explored, especially abundant on shores, in marsh forests, and pine bogs. Phthiracarus longulus, P. boresetosus, and Steganacarus carinatus occurred in abundance in coniferous forests, especially in the southern and central parts of the country, whereas Rhysotritia ardua was found there onl…
Three new species of the subgenus Neoribates (Neoribates) (Acari, Oribatida, Parakalummidae) from Nepal
2014
Three new parakalummid mites of the subgenus Neoribates (Neoribates), N. (N.) parabulanovae sp. n., N. (N.) paramacrosacculatus sp. n. and N. (N.) pararotundus sp. n., are described from Nepalese soils. Neoribates (Neoribates) parabulanovae sp. n. is morphologically most similar to N. (N.) bulanovae Grishina, 2009, N. (N.) rotundus Aoki, 1982 and N. (N.) setiger Balogh & Mahunka, 1978, however, it differs from N. (N.) bulanovae by the body length, body and leg integument, morphology of bothridial setae, absence of aggenital setae, length of interlamellar setae and location of adanal setae ad3; from N. (N.) rotundus by the body size, body integument, morphology of bothridial setae and le…
