Soil microbiome of primeval forest ecosystems in Transkarpathia
2018
The aim of this study was to investigate the soil microbiome of primeval forest ecosystems, namely the structure of microbial communities,the number of major ecological-functional groups, functional parameters such as: soil toxicity, as well as enzymatic activity of the soil by the level of catalase and invertase. To analyze the successional processes in the soil microbiocenosis due to the influence of endogenous and exogenous factors. To estimate the integrity of microbial communities in different edaphotopes of primeval forest ecosystems. Methods. Microbiological studies of soil were carried out according to generally accepted methods in soil microbiology. Enzymatic activity of the soil: …
Nest sites of a strong excavator, the Great Spotted Woodpecker Dendrocopos major, in a primeval forest
2017
In managed forests, birds that create their own breeding holes in trees have limited access to substrates in which they can excavate. Therefore, nest site use in these forests possibly reflects availability of substrates more than species preferences. We analysed data on nest sites of Great Spotted Woodpeckers Dendrocopos major collected during 1987–2013 in the strictly protected part of Białowieża National Park in East Poland. The woodpeckers excavated breeding holes in 11 tree species, but species used in individual habitats varied greatly: Alder Alnus glutinosa was almost the only species used in the riverine forest; Common Aspen Populus tremula, Common Hornbeam Carpinus betulus and Pedu…
Variation in timing of breeding of five woodpeckers in a primeval forest over 45 years: role of food, weather, and climate
2020
AbstractClimate warming could lead to ‘mis-matching’ of birds’ breeding times with availability of their invertebrate food resources. Fluctuating spring temperatures could influence variation in the commencement of egg-laying, as well as, in phenology of their resources (e.g., tree bud burst, appearance of folivorous caterpillars). We studied timing of Dendrocopos leucotos, Dendrocoptes medius, Dendrocopos major, Dryobates minor, and Picoides tridactylus breeding in, free of direct human intervention, strictly protected fragments of Białowieża Forest (Poland) in 1975–2019. We related their onset of breeding to inter-year variation in spring weather, trees’ bud burst and timing of folivorous…
Materiały do brioflory rezerwatu przyrody Boczki (Puszcza Romincka)
2017
The results of bryological investigations from the “Boczki” nature reserve, located in Puszcza Romincka Forest, are presented. The reserve was established in 1974 for protection well preserved forest communities characteristic of the Romincka Primeval Forest. 154 bryophyte species were recorded – 37 liverworts and 117 mosses, including 37 unpublished species from the Puszcza Romincka Forest. In respect of frequency the main group make rare species – 29.2%, the least numerous were frequent – 21.4%. Terrestrial and epixylic habitats were the richest – refer 98 and 85 species respectively. Significant were groups of protected (47) and endangered (14) species. There is also a large share of bry…
