Chrząszcze saproksyliczne Karkonoszy. Część I - wykaz gatunków
2016
Założenia. W północnej (polskiej) części Karkonoszy nie prowadzono dotychczas gruntownych studiów fauny związanej z obumierającymi drzewami i rozkładającym się drewnem, mimo że w latach osiemdziesiątych i dziewięćdziesiątych ubiegłego wieku środowisko tych gór zostało dotknięte klęską zamierania lasów. Do dzisiaj, w wyniku procesów rozpadu drzewostanów, utrzymuje się wysoki zapas martwych drzew i rozkładającego się drewna. Celem przeprowadzonych prac inwentaryzacyjnych było rozpoznanie chrząszczy saproksylicznych występujących w środowiskach leśnych Karkonoszy. Materiał i metody. Prace realizowano w latach 2013–2015 w 10 obiektach badawczych reprezentujących środowiska lasów regla dolnego, …
Habitat associations drive species vulnerability to climate change in boreal forests
2016
Species climate change vulnerability, their predisposition to be adversely affected, has been assessed for a limited portion of biodiversity. Our knowledge of climate change impacts is often based only on exposure, the magnitude of climatic variation in the area occupied by the species, even if species sensitivity, the species ability to tolerate climatic variations determined by traits, plays a key role in determining vulnerability. We analyse the role of species’ habitat associations, a proxy for sensitivity, in explaining vulnerability for two poorly-known but species-rich taxa in boreal forest, saproxylic beetles and fungi, using three IPCC emissions scenarios. Towards the end of the 21…
Choosy beetles : How host trees and southern boreal forest naturalness may determine dead wood beetle communities
2021
Wood-living beetles make up a large proportion of forest biodiversity and contribute to important ecosystem services, including decomposition. Beetle communities in managed southern boreal forests are less species rich than in natural and near-natural forest stands. In addition, many beetle species rely primarily on specific tree species. Yet, the associations between individual beetle species, forest management category, and tree species are seldom quantified, even for red-listed beetles. We compiled a beetle capture dataset from flight intercept traps placed on Norway spruce (Picea abies), oak (Quercus sp.), and Eurasian aspen (Populus tremulae) trees in 413 sites in mature managed forest…
Materiały do rozmieszczenia wybranych, chronionych chrząszczy saproksylicznych (Coleoptera) w województwie opolskim: pachnicy próchniczki Osmoderma b…
2021
The paper presents unpublished data on the occurrence of rare, protected species of saproxylic beetles: Osmoderma barnabita, Protaetia speciosissima, Lucanus cervus and Cerambyx cerdo in the Opole voivodeship (south-western Poland), together with maps of distribution. The paper also includes comments on the current situation of these species in the region and predictions about possible changes in their population trends. New sites of these rare beetles significantly improve the knowledge about their distribution in the region and will help local authorities in investments planning and natural resource management.
Dead wood profile of a semi-natural boreal forest – implications for sampling
2019
Dead wood profile of a forest is a useful tool for describing forest characteristics and assessing forest disturbance history. Nevertheless, there are few studies on dead wood profiles, including both coarse and fine dead wood, and on the effect of sampling intensity on the dead wood estimates. In a semi-natural boreal forest, we measured every dead wood item over 2 cm in diameter from 80 study plots. From eight plots, we further recorded dead wood items below 2 cm in diameter. Based on these data we constructed the full dead wood profile, i.e. the overall number of dead wood items and their distribution among different tree species, volumes of different size and decay stage categories. We …
Traits mediate niches and co‐occurrences of forest beetles in ways that differ among bioclimatic regions
2021
Aim The aim of this study was to investigate the role of traits in beetle community assembly and test for consistency in these effects among several bioclimatic regions. We asked (1) whether traits predicted species’ responses to environmental gradients (i.e. their niches), (2) whether these same traits could predict co-occurrence patterns and (3) how consistent were niches and the role of traits among study regions. Location Boreal forests in Norway and Finland, temperate forests in Germany. Taxon Wood-living (saproxylic) beetles. Methods We compiled capture records of 468 wood-living beetle species from the three regions, along with nine morphological and ecological species traits. Eight …
