Phoretic relationships between Plagionotus detritus (Coleoptera: Cerambycidae) and Trichouropoda sociata (Acari: Mesostigmata)

The aim of the study was to explore phoretic relationships between Plagionotus detritus and mites from the order Mesostigmata. In total, 635 individuals of P. detritus were caught, and mites were found on 86 of them. The dominant species among 8,154 individuals of mites was Trichouropoda sociata (8,152 individuals), and the sporadically found species were Lasioseius thermophilus (1 ind.) and Typhlodromus sp. (1 ind.). Generally, the difference in the total abundance of females and males of P. detritus was not statistically significant (311 females vs 324 males). The proportional abundance of P. detritus with T. sociata differed between samplings, and in the pooled data, the proportional abundance of P. detritus females with T. sociata (39.5%) was less than that for P. detritus males (60.5%)

Stephanopachys linearis (Kugelann, 1792) (Coleoptera, Bostrichidae) in Poland

Stephanopachys linearis (Kugelann, 1792) belongs to the family of horned powderpost beetles (Bostrichidae), represented in the fauna of Europe by 29 native species. It is a characteristic element of the northern, boreal zone of the Palaearctic and alpine areas of central and southern Europe. This species as a rare beetle important for the European Union, has been placed in Annex II of the Habitats Directive, on the IUCN Red List of Threatened Species and European Red List of Saproxylic Beetles. S. linearis was described from Poland in 1792 and, after 220 years, again encountered in this country. The zoogeographical distribution is shown and elements of its biology and ecology are discussed

Puszcza Białowieska : miniprzewodnik naukowy

"Dzisiejsza roślinność Puszczy jest wynikiem procesów ekologicznych, które kształtowały ją od schyłku ostatniego zlodowacenia, kiedy ocieplenie klimatu umożliwiło rozwój ekosystemów leśnych na tym terenie. Około 12 tysięcy lat temu rozprzestrzeniły się tu lasy sosnowo-brzozowe, a następnie kolejno przybywały inne gatunki drzew, które wędrowały z cieplejszych rejonów Europy, gdzie przetrwały okres zlodowacenia. Stopniowo wzbogacały one tutejsze lasy i powodowały ich zróżnicowanie w zależności od warunków siedliskowych. Do pierwszych przybyszów, po sośnie i brzozie, należały wiąz i leszczyna, a między ok. 9300 a 3800 lat temu miał miejsce najbujniejszy rozwój wielogatunkowych, mieszanych lasów liściastych." (fragm.

Meta-analysis of multidecadal biodiversity trends in Europe

Local biodiversity trends over time are likely to be decoupled from global trends, as local processes may compensate or counteract global change. We analyze 161 long-term biological time series (15-91 years) collected across Europe, using a comprehensive dataset comprising similar to 6,200 marine, freshwater and terrestrial taxa. We test whether (i) local long-term biodiversity trends are consistent among biogeoregions, realms and taxonomic groups, and (ii) changes in biodiversity correlate with regional climate and local conditions. Our results reveal that local trends of abundance, richness and diversity differ among biogeoregions, realms and taxonomic groups, demonstrating that biodiversity changes at local scale are often complex and cannot be easily generalized. However, we find increases in richness and abundance with increasing temperature and naturalness as well as a clear spatial pattern in changes in community composition (i.e. temporal taxonomic turnover) in most biogeoregions of Northern and Eastern Europe. The global biodiversity decline might conceal complex local and group-specific trends. Here the authors report a quantitative synthesis of longterm biodiversity trends across Europe, showing how, despite overall increase in biodiversity metric and stability in abundance, trends differ between regions, ecosystem types, and taxa.peerReviewe

New data on the occurrence of buprestid beetles (Coleoptera: Buprestidae) in the Białowieża Primeval Forest

The aim of this work was to expand current knowledge on the species composition and distribution of the jewel beetles (Coleoptera: Buprestidae) in Białowieża Primeval Forest (BPF) based on research conducted in 2000–2018 and a literature review. The BPF is considered the best-preserved forest of the European lowland and is a reference point for all forest research. Thus, knowledge of its fauna is vital. This research was conducted and incorporated the whole Polish part of the BPF, including Białowieża National Park (BNP), using standard methods for the faunistic studies of terrestrial beetles. We also investigated potential microhabitats of saproxylic buprestid beetles and reared larvae from inhabited host material. Collected larvae and/or pupae were identified in the laboratory or grown to the adult stage. However, most specimens were collected using various traps (Lindgren, Moericke, Netocia barrier type and IBL-2), especially traps placed in the upper tree canopy
