Long-term studies on the springtail fauna of the Harz Mountains (PR III)
From 14th to 18th of October 2016 soil and moss samples were taken again from a total of 17 sites (see map) of the Harz. All samples were selected using an expedition Berlese device (see photo). In the foreground of these investigations stood 2 bolder fields and sites in older deciduous forests. The determination of the whole material will start in January 2017.
Contribution to the knowledge of Collembola from the Canary Islands
In the seventies and eighties of the last century Arne Fjellberg und Willem N. Ellis collected springtails within many locations of the Canary Islands. They mainly took mosses of rocks, litter layers or netted from vegetation (e. g. meadows). A part of these collected springtails samples Dr. Fjellberg gave kindly our section Apterygota. These undetermined materials were and will currently determine.
Within the Fauna Europaea (last update 29 August 2013) 103 (sub) species are listed for the Canary Islands. Already the first determinations yielded some new records; e. g. Sminthurus hispanicus Nayrolles, 1995, Desoria trispinata (MacGillivray, 1896) and Caprainea bremondi (Delamare Deboutteville & Bassot, 1957). Remarkable is also the again record of Mesogastrura libyca (Caroli, 1914) from Tenerife.
Continuation of long-term studies on Collembola fauna in bogs
Samples of the Dubring bog from 2012 were determiniert. These samples resulted in altogether 50 species. Besides of many hydrophilic species three tyrphobiotic species were found (Ceratophysella scotica (Carpenter & Evans, 1899), Neelides minutus (Folsom, 1901) and Pachyotoma crassicauda (Tullberg, 1871)).
Furthermore the examination of extensive samples from the Sernitz bog project of Dr. Ricarda Lehmitz (Section Oribatida ) started. With Neelides minutes and Pachyotoma crassicauda also two tyrphobiotic species were already recorded. Above all 4 collecting dates were analyzed (July, October 2013, November 2015 and April 2016). Within these samples 49 species were found (7419 specimens).
Strict forest reserves in Hesse study of the Collembola fauna of the forest reserve “Locheiche”
The forest reserve ‘Locheiche’ is a part of the national park ‘Edersee-Kellerwald’. This region is characterized by old large-scale beech forests. The soil and moss samples (more than 100 of nearly 50cm3 volumes) were taken in March, May and September 2009 within a grid-based sampling design of the Locheiche woodland.
Nearly 10 000 specimens were collected and resulted in 44 species (preparation and determination from May to July 2016). The majority of the recorded species are eurytopic, but also some typical forest inhabitants were found (e.g. Desoria violacea, Lipothrix lubbocki, Micraphorura absoloni and Willemia denisi). Furthermore characteristic dwellers of moss/lichens on rocks and trees were found: Anurophorus laricis, Pseudisotoma sensibilis and Xenylla boerneri. Most frequent within the soil samples were Mesaphorura macrochaeta and Parisotoma notabilis.
