Microplastics (MPs) have even been detected in remote environments, including high-latitude regions, where human activities are restricted or strongly limited. We investigated the surface water of the bays of the Barents Sea and the freshwater lakes that are located close to and several kilometers from a year-round resident field station in the rem...

Dinocampus coccinellae (Schrank) is a braconid parasitoid of ladybird beetles (Coleoptera: Coccinellidae) and has exceptionally wide geographical and host ranges. Based on published and unpublished sources Dinocampus coccinellae probably occurs throughout the temperate, subtropical and tropical climatic zones, but some regions, such as sub-Saharan...

Laboulbeniales (Ascomycota, Laboulbeniomycetes) are biotrophic microfungi always attached to the exoskeleton of their arthropod hosts. They do not form hyphae or a mycelium; instead, they undergo determinate growth, developing from a two-celled ascospore to form a multicellular thallus. Hesperomyces virescens has been reported on over 30 species of...

Ladybird beetles (Coccinellidae) were collected at 11 sites on the island of Madeira from 4 th to 10 th of February 2020.

Because of the scale and speed of species extinctions conservationists require methods that facilitate decision making. Therefore, a wide range of habitat and population viability analysis (PVA) software has been developed. Given the diversity of available programs it is currently challenging to decide which program is the most appropriate for a pa...

Muskrat, Ondatra zibethicus (L. 1766), is an introduced species to European fauna. It is widespread in Poland, however, signs of its decline were observed in the last decades.

Phylogenetic analyses based on mitochondrial 16S rDNA, nuclear 28S rDNA, and morphological and ecological traits of Aulactinia, Urticina and Cribrinopsis sea anemones inhabiting the Arctic-boreal region indicate discordances between trees derived from molecular sequences and those based on morphological traits. Nuclear genes were more informative t...

Otters (Lutra lutra) mark territories by depositing feces on prominent spots, like rocks or large tussocks of grass. However, sometimes they defecate on intentionally mounded heaps made of mud and/or plant material. We show that in sites occupied by otters the frequency of heap-making significantly increases with the frequency of otters occurrence...

The genetic interests of males and females usually differ. Whenever female fitness depends on an access to limited resources such as male parental care, competitive interactions among females are expected to evolve. There are numerous studies reporting female-female aggression during the breeding season, but this subject has not been examined for t...

Analiza danych przestrzennych przy wykorzystaniu specjalistycznych aplikacji takich jak ArcGIS znajduje coraz większe zastosowanie w wszelkiego rodzaju badaniach mogących służyć ochronie przyrody.

Owl pellets have high potential as a source of DNA. However, this non-invasive method of collecting DNA is rarely used and its methodological aspects are poorly understood. We investigated the methodology for DNA extraction and amplification from owl pellets containing the smallest European rodent – the Harvest mouse Micromys minutus – as an exampl...

Animals can estimate breeding habitat quality by monitoring social information provided by the behaviours of others. While it is accepted that the value of public information erodes with distance from the source of information, the spatial and temporal ecology of public information acquisition and use is not well understood.

The Eurasian otter (Lutra lutra) populations declined in large areas of Europe during the 20th century. However, the increase in otter populations in their natural range and recol-onization processes are recently observed in several European countries. As revealed by the first national survey, otters were already widespread in most of the Poland ex...

The otter, which causes damage to fish farming industry, is considered to be a conflict species. This is why it has been included in the project: "Preparation of national strategies for the management of selected endangered and conflict species". The outcome of this project is the "National Action Plan for the Otter Lutra lutra in Poland. The Natio...
