False Mating of Blackbirds () and Fieldfares ().

During an intensive study of the urban population of the blackbird in Szczecin (1997-2023), four cases of surrogate copulation were observed in the blackbird and three in the fieldfare . In three cases, birds (blackbirds twice and fieldfare once) try to copulate with fledglings of their own species, and in all other cases, the birds try to copulate with moss and sticks. In three cases copulation, attempts were done by adult birds (two blackbirds and one fieldfare), and in four cases, it was a fledgling.

IoT in Water Quality Monitoring-Are We Really Here?

The Internet of Things (IoT) has become widespread. Mainly used in industry, it already penetrates into every sphere of private life. It is often associated with complex sensors and very complicated technology.

Changing natural conditions and their impact on the Mt. Śnieżnica landscape, Outer Western Carpathians - Reconstruction of the Holocene environment based on geochemical indices and radiocarbon dating.

Environmental changes during the Holocene impacted the development of all civilizations, and it is important to understand the power of this influence through, for instance, the reconstruction of these changes. However, when the climate and environmental conditions of the deep past are analyzed, researchers need to rely on various types of proxy data that are only approximations of the required information. In addition, this type of information is often absent or has several gaps (hiatuses).

Sequentiality of beetle communities in the longitudinal gradient of a lowland river in the context of the river continuum concept.

The main goal of the study was to recognize the mechanisms underlying assemblage structuring of aquatic beetle fauna inhabiting a medium-sized, lowland river exposed to anthropogenic pressures. An attempt was made to identify the impact of numerous abiotic factors on how beetle communities are formed, with particular emphasis on geomorphological and landscape-related factors, which tend to be omitted from many studies of aquatic organisms. Our intention was to refer the results of our study to the general assumptions of the River Continuum Concept.

Anthropogenic transformations of river ecosystems are not always bad for the environment: Multi-taxa analyses of changes in aquatic and terrestrial environments after dredging of a small lowland river.

Rivers are one of the most commonly transformed aquatic ecosystems. Most papers present significantly negative effects of activities such as dredging or channel regulation on the ecological status of rivers. The purpose of this work was to compare the response of various groups of invertebrates (Mollusca, Hydrachnidia, Odonata, Heteroptera, Coleoptera and Trichoptera) to an intervention involving dredging in conjunction with the removal of riparian vegetation.

First detailed records of water mite larvae (Hydrachnidia: Hydrovolzidae, Hydryphantidae) parasitizing empidid flies (Diptera: Empididae: Clinocerinae).

Five species of the subfamily Clinocerinae from the Tatra Mountains (S Poland) were observed to be parasitized by larval water mites. Two of them: Mik, 1880 and Mik, 1880 are recorded from this massif for the first time. In addition, is new for Polish fauna.
