Objective: In soil habitats, mesostigmatic mites (Acari: Mesostigmata) are among the most important predators of smallarthropods and nematodes. Methods: A study was carried out during 2009-2010 to identify theirfauna in Khorramabad county, Western Iran. Soil samples were taken from different regions. Mites were extracted by Berlese-Tullgren funnel and cleared in nesbit fluid. Microscopic slides...

Nineteen zooplankton species of them belonging to 15 Rotifera, 2 Cladocera, 2 Copepoda were recorded from Çat Dam Lake (Malatya). One of these species, Lecane intrasinuata (Olofsson, 1917) is a new record for Turkish rotifer fauna.

new faunistic records for 15 species of salticidae for the spider fauna of iran are presented. five species (langona aperta, mogrus antonius, pellenes bonus, p. geniculatus and sitticus karakumensis) are new records for the spider fauna of iran.

Large cetacean carcasses at the deep-sea floor, known as ‘whale falls’, provide a resource for generalistscavenging species, chemosynthetic fauna related to those from hydrothermal vents and cold seeps, and remarkable bone-specialist species such as Osedax worms. Here we report the serendipitous discovery of a late-stage natural whale fall at a depth of 1444 m in the South Sandwich Arc. This di...

Sirs — Graptolites of Arenig age have been discussed repeatedly from the Ballantrae Complex (Stone & Strachan 1981; Stone & Rushton 1983, 2003; Rushton et al. 1986; Rushton & Stone 1988). The inferred biostratigraphic ranges were estimated to be from the basal Arenig Tetragraptus approximatus Biozone to the early Yapeenian. As the exact dating of the graptolite faunas in this sequence has some ...

BACKGROUND Species distribution, abundance and diversity of mangrove benthic macroinvertebrate fauna and the relationships to environmental conditions are important parts of understanding the structure and function of mangrove ecosystems. In this study seasonal variation in the distribution of macrobenthos and related environmental parameters were explored at four mangrove stations along the Po...
