Abstract
The paper deals to the diversity and ecological features of the early spring ascomycetous fungi (Ascomycota) in the National Nature Park "Skolivski Beskydy". The results of the study were identified 51 species of the ascomycetous fungi. These collected fungi belong to 4 classes, 7 subclasses, 12 orders, 18 families, 37 genera, also to the anamorphic fungi incertae sedis Pezizomycotina, that belong to the phylum Ascomycota. Ascomycetous fungi is representing 3 ecological-trophical groups: biotrophs, saprotrophs, symbiotrophs. Among the identified species in early spring, 24 representatives are new to the study area, 18 of which – actually early spring and 6 species – "found in the spring". Analysis of distribution of ascomycetous fungi species for ecological trophical groups showed the considerable prevailing of saprotrophs (41 species). Saprotrophs species distributed into 7 subgroups. Significantly fewer (10 species) are biotrphs, that are distributed in 5 subgroups. Symbiotrophs is representing 3 mycorrhizal species of fungi, that also belong to the terrestrial saprotrophs. The paper includes the list of identified species of the early spring ascomycetous fungi, ecological features and distribution for ecological-trophical groups.
Highlights
Conservation of any species is usually impossible without protection of habitats important for their breeding, foraging, resting etc
The analysis of Black Stork spatial distribution in relation to forest habitat types was performed in the territories of eight forestry companies in the Rivne region of Ukraine, which overlap with the Polissya nature zone and with the kernel of Black Storks highest population density, as well as with the main part of the breeding range of this species in Ukraine
Usage of forest habitats by Black Stork in Rivne region The results of the analysis show that there is a strong correlation between the Black Stork habitat selection and the general structure of forests in the region, on each of the analysis levels
Summary
Conservation of any species is usually impossible without protection of habitats important for their breeding, foraging, resting etc. Most of them are based on the studies made in Central and East European countries [1, 4, 7, 11, 12 etc.], mostly Baltic countries, which is reasonable, taking into account the species distribution in Europe and the sizes of national populations [2, 10]. Ukraine possesses a significant part of the European Black Stork population [2, 10] and is interesting as a territory of breeding range margin, where European Forest zone borders with steppes. One study [14] was related to habitats and their changes but was mostly analytical and based on expert opinions without appropriate raw numerical data. Current publication aims to fill some of gaps in this area of Black Stork studies using GIS approach
