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 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.
Due to fewer bumblebees in rural areas these days, it is necessary to look for alternative habitats for the active protection of these very important pollinators. The research was carried out in The Botanical Garden of Medicinal Plants, in Wrocław, Poland. In the garden, approximately 2000 plant species were cultivated, of which 185 were visited by bumblebees. Amongst them, 57 plant species were deemed very attractive and were determined to be indicators for 7 bumblebee species. Indicator species for bumblebees ranged between 6 for Bombus pratorum to up to 20 for B. pascuorum. Monarda didyma was an indicator plant to 6 recorded bumblebee species. Other indicator plant species for at least 4 bumblebees species were: Origanum vulgare, Lavandula angustifolia, Rhododendron catawbiense, Phacelia tanacetifolia, and Agastache rugosa. Three bumblebee species were found to forage the most on 11 of the flowering plant species. The biggest group of plants were those which were mostly visited by 1-2 bumblebee species. Amongst all recorded indicator plants, 32% were native species.
