Lack of specialist nidicoles as a characteristic of mite assemblages inhabiting nests of the ground-nesting wood warbler, Phylloscopus sibilatrix (Av…
2021
AbstractBird and mammal nests provide microhabitats that support a range of other species, including invertebrates. However, the variation between communities of nest-dwelling invertebrates in different nests is poorly understood. The major aim of this study was to analyze the assemblage structure of mites from the suborder Uropodina (Acari: Mesostigmata) and from superfamily Crotonioidea (Acari: Oribatida) inhabiting nests of the wood warbler, Phylloscopus sibilatrix (Aves: Passeriformes), located on a forest floor in Białowieża Forest, in eastern Poland. We also assessed the correlation between the nest material used by the birds with the assemblage structure of Uropodina mites, and compa…
Immediate Effects of Prescribed Burning on Soil Mite (Acari: Oribatida) Communities in a Scots Pine (Pinus Sylvestris) Forest, Latvia
2021
Abstract Prescribed burning is used to maintain and restore habitats, to protect and increase species bio-diversity. Knowledge about soil fauna is limited, especially on community responses to fire disturbances. The aim of this study was to determine the immediate effects of prescribed burning on soil armoured mite (Acari: Oribatida) communities, vegetation cover and soil physiochemical properties in a boreal Scots pine forest in Latvia. Soil samples were collected on the day of the prescribed burning in the protected landscape area “Ādaži” and 16 days after. No significant changes in abiotic factors were found. Fire significantly decreased the vegetation cover. After the burning, the total…
Additions to the Indian oribatid mite fauna, with description of a new species of the genus <em>Niphocepheus</em> (Acari, Oribatida)
2014
An annotated checklist of oribatid mite taxa from three sites of India is presented. It includes 71 species/ subspecies, 55 genera and 35 families. Twenty nine species/subspecies are recorded for the first time in India; five species/subspecies—Trhypochthonius tectorum stercus, Hermanniella aliverdievae, Sphodrocepheus tridactylus, Caenosamerus spatiosus, Dolicheremaeu distinctus—are recorded for the first time in the Oriental region. Niphocepheus neotrichus sp. nov. (Niphocepheidae) is described; it differs from other known species of Niphocepheus by the presence of epimeral neotrichy and three pairs of anal setae.
<strong>Two new species of oribatid mites of the genera <em>Pergalumna</em> and <em>Carinogalumna</em> (Acari, Oribatid…
2014
Two new species of oribatid mites of the family Galumnidae, Pergalumna minituberculata sp. nov. and Carinogalumna alineata sp. nov., are described from soil of secondary mixed broadleaved forest with bamboo in eastern Nepal. The genus Carinogalumna is recorded for the first time in the Oriental region. Pergalumna minituberculata sp. nov. is similar morphologically to Pergalumna longisetosa Balogh, 1960 and Pergalumna paralongisetosa Ermilov & Kaluz, 2012, however, it differs from both by the body size, length of bothridial and adanal setae, absence of porose areas Ad, and the presence of notogastral setae c, medial pore, postanal porose area, striate genital plates and striate bands in anog…
Oribatid mites (Acari: Oribatida) in boreal forest floor and decaying wood
2008
Summary We studied the oribatid mite communities in forest floor and in decaying wood in pine (Pinus sylvestris), spruce (Picea abies) and deciduous (mainly Betula pendula and B. pubescens) forests at different latitudes in Finland. The study sites were either in mature managed forests or in old-growth forests in nature reserves. Altogether 78 sites were sampled in 2004 and 2005, yielding a total of 38,145 oribatid mites belonging to 133 species, of which four were new to Finland. Oribatid mite communities differed in terms of total number and community structure between forest types and latitudes within the boreal forest zone. The most abundant and diverse communities were in spruce forest…
Use of Quantitative Morphological Analysis Combined with a Large Sample Size for Estimating Morphological Variability in a Case Study of Armoured Mit…
2015
Abstract The morphology of Oribatida and similar little-known groups of organisms varies considerably, which complicates morphological analysis (e.g. species descriptions). Qualitative analyses have been carried out mostly on a small number of individuals (n < 25). There is lack of studies dealing with mechanisms of how that variation can change in relation to sample size and insufficient discussion on whether qualitative or quantitative analysis is more appropriate for description of morphological variability. A total of 500 adult Carabodes subarcticus Trägårdh, 1902 Oribatida were collected from a local population. Six qualitative and six quantitative traits were characterised using li…
Bruņērču (Acari: Oribatida) dzimtu sastāvs un ietekmējošie faktori mājputnu ganību augsnēs bijušā kolhoza "Valmiera" teritorijā
2021
Ar mājputnu ganību izveidi tiek ietekmēti zālāji, un augsnē dzīvojošās bruņērces (Oribatida), kuras ietekmē mājputnu ganību raksturojošie vides faktori - nomīdīšana, putnu mēsli, apkārtējās faunas un floras maiņa, u.tml. Mainoties vides faktoriem zālājos, tiek ietekmētas bruņērču sabiedrības, to dažādu dzimtu sastopamība, sastāvs un indivīdu blīvums. Darba mērķis bija raksturot mājputnu ganību dažādas intensitātes ietekmi uz bruņērču dzimtu sadalījumu un dominējošām dzimtu grupām antropogēni noslogotās augsnēs bijušā kolhoza “Valmiera” teritorijā. Bakalaura darba ietvarā tika ievākti un pētīti augsnes paraugi bijušā kolhoza “Valmiera” teritorijas augsnēs, tā atrodas netālu no Valmieras pils…
Kontrolētas dedzināšanas ietekme uz augsnes bruņērču (Acari:Oribatida) sugu sabiedrībām priežu mētrājā, aizsargājamo ainavu apvidū "Ādaži"
2018
Bruņērces līdz šim ir maz izmantotas sukcesiju pētījumos un zināšanas par augsnes faunas un bruņērču atbildes reakcijām uz dažādiem traucējumiem ir ierobežotas, taču to relatīvi lēnais dzīves cikls un plašā izplatība tās padara par efektīviem ilgtermiņa bioindikatoriem, kas var liecināt par degšanas ietekmes smagumu. Darba mērķis ir noskaidrot kontrolētas dedzināšanas ietekmi uz augsnes bruņērču sabiedrībām, zemsedzi un augsnes parametriem priežu mētrājā. Augsnes paraugi ievākti pirms un 16 dienas pēc kontrolētas dedzināšanas. Pēc degšanas bruņērču indivīdu skaits samazinājies par 93% un sugu skaits par 77%. Izmaiņas ietekmē degšanas ietekmes smagums. Pēc traucējuma eudominējošs taksons ir …
Two new species of oribatid mites of Lasiobelba (Acari, Oribatida, Oppiidae) from Nepal, including a key to all species of the genus
2014
Two new species of oribatid mites of the genus Lasiobelba (Oribatida, Oppiidae), Lasiobelba (Lasiobelba) daamsae sp. n. and Lasiobelba (Antennoppia) nepalica sp. n., are described from eastern Nepal. Lasiobelba (L.) daamsae sp. n. is most similar to L. (L.) remota Aoki, 1959 and L. (L.) gibbosa (Mahunka, 1985), however, it differs from both by the anterior part of pedotecta I specifically curved, rostrum pointed and exobothridial setae not shorter than bothridial setae. Lasiobelba (Antennoppia) nepalica sp. n. is most similar to L. (A.) granulata (Mahunka, 1986), however, it differs from the latter by the larger body size, exobothridial setae longer than rostral setae and bothridial setae n…
