The avifauna of the National Nature Park "Homilshanski Lisy"

Abstract

In the recreational zone of "Homilshanski Lisy" National Park 137 species of birds were identified during the period 1980–2015, of which 127 species nest, 8 winter, and 2 observed during the spring migration. The nesting species are distributed in 4 ecological groups dominated by dendrophylls (67 species), with fewer limnophylls-fresh water species (29), campophylls-open country species (16) and sclerophylls (11). Among the nesting birds 11 landscape-genetic faunal assemblages were distinguished, dominated by typical nemoral-woodland (19%), tropical (14%) and forest-steppe (13%) species. The average density of the birds nesting in the park amounts to 1.2 ± 0.2 with n overall density of 148.3 pairs/km route line. The habitat distribution of the bird population was relatively even. The most intensively populated habitat was upland oak forest, the least were pine and mixed forests. It was found that the communities of breeding birds in tree plantations changed due to the natural aging process of forests, which has led to an increase in the number of birds of prey (Falconiiformes), woodpeckers (Piciformes), secondary hollow-nesting birds. The bird communities of floodplain and steppe meadows, as well as habitats in residential areas subject to constant recreational pressure, changed under the pressure of anthropogenic loading. The favorable natural and geographical location of the park and the diversity of its habitats contributed to the emergence in the list of fauna of which are expanding their range. Analysis of the dominant species in the community points to a significant negative impact of recreational pressure on all habitats of the park. The dominant birds in the pinewood community list included only one campophyll, tree pipit (Anthus trivialis L.). For the steppe meadows, in addition to the dominant colonial birds that nest in holes , the yellow wagtail (Motacilla flava L.) was marked as subdominant. In general, in the recreational area of NPP "Homilshanski Lisy" 30 common species (24.2%, total abundance 0.198) nest on the ground. The variety and balance of breeding bird communities in most habitats is stable, but in the meadow ecosystem communities the uniformity of the distribution of species abundance is being significantly disrupted. The Jacquard and Sorenson performance indices for floodplain and steppe meadows are 0.4 and 0.5, and for grove and pine woods, respectively, 0.7 and 0.8. Taking into account the data of the cluster analysis, the distribution curves of shared abundance and participation indicatee sinanthropic breeding bird communities. It follows that anthropogenic pressure exerts the most significant effect on the birds’ occupation of breeding habitats in the recreational zone NPP "Homilshanski Lisy". The highest performance is characterized by the condition of the avifauna of forest habitats, such as oak forest and pine woods, the most threatened breeding bird communities being those of floodplain meadows.

Bird Communities and Vegetation Composition in the Urban Forest Ecosystem: Correlations and Comparisons of Diversity Indices

“…If the biotope transformation exceeds the threshold of adaptability of a certain species, it leaves the urban forest forever. Limited and specialised species reducing locality under conditions of transformation of natural ecosystems eliminate from the communities of nesting birds (Shupova, 2001;Chaplygina et al, 2016;.…”

“…Variations of characteristics of the forest ecosystem, formed under the influence of urban recreation, have shown the relationships between phytocoenotic parameters and species diversity and density of nesting birds (Conner, Dickson, 1997;Chaplygina et al, 2016).…”

Syn-Ecological Connections and Comparison of Α-Diversity Indices of Plant and Bird Communities on Cultivated Coenosises

“…In order for studying biodiversity, it is relevant to research on consortium linkages as specific ecological phenomena (Lavrov & Blinkova,63 2018; Blinkova & Ivanenko, 2018). Consideration of the transformation of 'tree-birds' consortium linkages in increasing insight on anthropogenic changes in the condition, productivity and development of tree stands as well as the fulfillment of their target functions is at an early stage (Chaplygina et al, 2016). In order to evaluate the anthropogenic impact effects on botanical gardens, it is advisable to carry out an analysis on a syn-ecological basis with the linkage between phyto-and zoological components (Blinkova & Shupova, 2017.…”

“…In an urbanized environment, they easily inhabit transformed biotopes (Kurosawa, 2009;Shupova, 2014Shupova, , 2017 and adapt themselves to the residence under permanent anthropogenic load. Variations in the composition of bird groups formed under the influence of anthropogenic load make it possible to identify the ecosystem balance degree (Chaplygina et al, 2016). Due to recreational effect, terrestrial microstations for birds disappear in biotopes.…”

“…Значні втрати лісових насаджень, зокрема в зелених зонах великих міст за останні два століття, є одним із вирішальних чинників швидких темпів опустелювання, деградації ландшафтів, глобальних змін клімату [3]. Перетворення ландшафтів, що відбувається під впливом діяльності людини, має пряме відношення і до зникнення нечисленних видів тварин, які особливо різко реагують на скорочення місць проживання [4]. Часто результатом дії надмірного антропічного пресу, є елімінація з угруповань тварин, які не адаптувалися до сусідства людини, аборигенних видів і формування нового угруповання [5].…”
