The study provides a comprehensive list of publications concerning data on spider distribution in Poland. A list includes 1089 original papers, book chapters, books, conference papers with original ...records on spider species from the contemporary territory of Poland. The list was updated as of December 31, 2020.
This is the first record of the European yellow sac spider Cheiracanthium punctorium (Villers, 1789) from the Lublin Upland (SE Poland). A dozen or so silk nests containing these spiders were found ...among goldenrod stems (Solidago sp.) on a dry meadow near Chodel, a village in the valley of the River Chodelka on 8 October 2021.
Micaria nivosa L. Koch is a rare spider belonging to the Gnaphosidae family. The paper presents an analysis of historical data, synonyms, diagnostic features and a number of new localities of M. ...nivosa in Poland.
Sex ratio (ratio between the number of male and female individuals in a population) is an important factor contributing to the survival rates of the population in wild. Imbalanced sex ratio is often ...the cause of diminished survival rates of endangered species. The analysis of DNA collected through noninvasive methodologies effectively allows to monitor populations of rare species or species that are difficult to observe in the wild. Such method was used to determine the sex ratio in populations of the capercaillie (Tetrao urogallus) and black grouse (Lyrurus tetrix) in the Tatra National Park. We collected over 250 samples (mostly excrement) in the area of the Tatra National Park and identified species via microsatellite genotyping and determined the sex using fragments of the CHD gene. We found that the majority of the samples belonged to male specimens irrespective of the species suggesting a large deviation from an equal sex ratio in wild populations of capercaillie and black grouse in the Tatra National Park. Our results point out the fundamental contribution of genetic assessment of sex ration to monitor the viability of both species in the Tatra National Park.
The collection of the scuttle flies (Diptera, Phoridae) visiting flowers of Cryptogorynae crispatula (Araceae) caught in Yunnan, China were studied. They were identified to 24 species of which only ...five were known, seven species are hereby described as new to science and next 13 species cannot be named until linked to their opposite sexes. The following are described. Conicera species female YG, cannot be named until linked to its male. Dohrniphora guangchuni n. sp., Megaselia duolobata n. sp., M. excrispatula n. sp., M. interstinctus n. sp., M. leptotibiarum n. sp., M. menglaensis n. sp., M. shooklinglowae n. sp., Megaselia species Y1 female that cannot be named until linked to its male. The recognition of M. chippensis (Brues, 1911), described from a single female, is augmented. Males of 6 species (Y1-Y6) of Puliciphora Dahl, cannot be named until linked to their females and 5 species of Woodiphora Schmitz.
In 2018–2019, the occurrence of Cordulegaster bidentata Selys, 1843 in the Wielickie Foothills, located between the Beskidy mountain ranges (in the south) and the Vistula river valley (in the north) ...was investigated. It was examined whether C. bidentata inhabits fragmented landscape, with forest patches of various sizes. Larvae of this dragonfly were searched in the forest streams, the bottom of which was visually scanned using binoculars. The presence of 49 larvae was confirmed on 17 stream sections out of 53 (32%). They were recorded in almost the entire geographical extent of the study area, from the southernmost to the northernmost forest patches. The neighboring occupied streams were separated by a maximum of 3.7 km, and breeding sites were found in forest patches of an area of 75–1280 ha. It was confirmed that C. bidentata occurs up to the orographic edge of the Western Carpathians. Its range is continuous between the northern edge of the Beskidy Mountains and the Vistula valley. New data shift the northern range limit of C. bidentata in the Western Carpathians by nearly 20 km. The field method used proved to be efficient in assessing the distribution of larvae in large areas, with relatively little field effort. Its wider use would allow a more complete recognition of distribution of C. bidentata in the Carpathian Foothills.
The background colouration of the spadefoot toad Pelobates fuscus, an anuran species found in Europe is typically light grey/yellow grey/light olive-green. However, an atypical specimen, whose ...background was brightly coloured yellowish green (light green/lime/yellow coloured), with darker small spots distributed through dorsal parts and four main spots slightly shaped was observed in Poland (Great Poland, Mościejewo village), near to two ponds. The ecological effects of green coloured individual can be adaptively important, through its similarity to the vegetation (predator avoidance).
The paper presents data about the first record of Andrena chrysopus Perez, 1903 in Bydgoszcz, Poland (the Wielkopolsko-Kujawska Lowland). It is an oligolectic species, closely linked to plants in the ...genus Asparagus sp. During 2018–2019 (May–June), 54 speciemens of the species were collected at 9 sites during the flowering period of the host plant. The bees were recorded in dry and well sunlit biotopes on the outskirts of the city and in residential-industrial districts. The observations confirmed the occurrence of stable populations of A. chrysopus. However, increasing urbanisation and succession may threaten the presence of the species in the genus Asparagus sp., and thus A. chrysopus, which strongly relies on these species' food sources.
