Are the Angels, Barnea candida (Myoida, Pholadidae), Backing to the Danube Delta in the Black Sea?

Abstract

Bivalve marine mollusc Barnea candida (= Pholas candidus) from Pholadidae family is sensitive to the high concentration of organic matter in sea water and recently has been included into the list of indicator species for the Black Sea (Alexandrov, Zaitsev, 2016). Its recording in Ukrainian part of the Danube Delta after more than 60 years since its first registration is probably the evidence of reduction of eutrophication and gradual restoration of local aquatic ecosystem biodiversity.

The Analysis of the Forest Flora of the Strzyżowskie Foothills from the Perspective of Presence of Anthropogenic Species

The Analysis of the Forest Flora of the Strzyżowskie Foothills from the Perspective of Presence of Anthropogenic Species

The anthropogenic pressure of the forest communities of the Strzyżowskie Foothills (the Western Carpathians) was estimated on the basis of phytosociological materials. Carr communities are among the most threatened by invasive and alien species of the forest flora. The phenomenon of invasiveness of native species such as Calamagrostis epigejos or Carex brizoides was described. The highest number of ancient woodland indicator species was noted in the beech forest.

Carex disperma – not yet extinct species in old-growth swampy forests of Lithuania

Abstract

Uselis V., Uselienė A., 2012: Carex disperma - not yet extinct species in old-growth swampy forests of Lithuania [Carex disperma - dar neišnykusi pelkinių sengirių rūšis Lietuvoje]. - Bot. Lith., 18(1): 13-18. The paper describes the locality of Carex disperma reaffirmed after a century; the locality is situated in the present territory of the Viešvilė State Strict Nature Reserve. Plants were found in an old swampy spruce forest, which, according to the geobotanical description, corresponds to the Sphagno girgensohnii-Piceetum Polak. 1962 association. The stand is rich in indicator species of an old-growth forest. Twelve Carex disperma individuals, growing in the area of 3 m2, were recorded in 2009. One more locality has recently been found in Utena region, but it has not been published in scientific references yet. Information on other localities of this species in Lithuania is either very old (mid-19th century) or not confirmed by the herbarium specimens.
