The burrowing crayfish Parastacus pugnax (Poeppig, 1835) inhabits the flooded plains in the central part of Chile (32–38°S), where it coexists with another representaives of invertebrate fauna. The aim of this study was to give the first description based on exploratory data of invertebrates associated to P. pugnax habitats in the Araucanía region, Chile. For comparison, published data on two similar habitats without P. pugnax populations were considered as outgroups. The obtained results revealed marked differences in species composition among sites with presence of P. pugnax, and without this species. A small number of species (1–5) was identified in the studied sites; Cladocera Simocephalus expinosus group was the most numerous and inhabited five of seven sites. Ecological and biogeographical topics were discussed.

Started by G. R. von Frauenfeld, R. Schiner and G. Strobl over 120 years ago by collecting several species in “Dalmazien”, studies of the fruit flies (Tephritidae) and picture-winged flies (Ulidiidae) in Croatia to date have been casual and fragmentary. Regular collecting of these families in Modruš (Karlovac County) during 2021–2022 has resulted in a list of 85 species of Tephritidae and 15 species of Ulidiidae presented here, of which 21 Tephritidae and three Ulidiidae species, respectively, are recorded from Croatia for the first time. Examined material and references are listed, and the rare or newly recorded species are illustrated. The status of type specimens of some nominal species described by Frauenfeld and Schiner from Croatia is discussed.
120多年前，G. R. von Frauenfeld, R. Schiner和G. strobel在“Dalmazien”收集了几个物种，迄今为止，对克罗地亚果蝇(绢蝇科)和画翅蝇(乌氏蝇科)的研究一直是偶然和零碎的。在2021-2022年期间，在莫德鲁什(卡尔洛瓦茨县)定期收集这些科，得出了85种网蝗科和15种网蝗科的名单，其中21种网蝗科和3种网蝗科分别是首次在克罗地亚记录到的。已检查的材料和参考文献被列出，稀有或新记录的物种被说明。本文讨论了克罗地亚的Frauenfeld和Schiner描述的一些名义种的模式标本的现状。

The structure of spined loaches diploid-poliploid complex of Cobitis genera representatives as well as Sabanjeewia aurata of the Eastern Ukraine river systems were investigated by allozyme analysis and cytometry. In total 39 samples and 1412 specimens from the upper left tributaries of the Dnieper River, the Donets Basin, the coastal rivers of the Azov Sea and the Lower Dnieper were studied. We identified the representatives of C. (superspecies taenia) (51,6% of all researched specimens). C melanoleuca (4,1%), S. aurata (1,1%), allodiploids C. (superspecies taenia) × C melanoleuca (0,3%) and two groups of polyploid hybrids (46,4%). EET-group includs mainly C. elongatoides – 2 taenia and C. elongatoides – taenia – tanaitica. EET-group (2,8%) is represented only by C. elongatoides – 2 tanaitica biotype. In the Lower Donets and the Lower Dnieper, there is a zone of introgressive hybridization between C. taenia and C. tanaitica. The structure of settlements differs accordingly to the river basins and has a tendency to decreasing of polyploids frequency respetivly to meridional direction. The analysis of loaches samples from the coastal rivers of the Azov Sea collected in 1938 and samples from the Middle part of the Donets River in 1971 leads to the conclusion that polyploids in mentioned above regions appeared in 1960-1970s. The structure of diploid-polyploid settlements has an alternative character. More often, there is a predominance of diploids or polyploids. The reason of such bipolarity of settlements could be as reproductive displacement so a relatively strong tolerance of polyploids to anthropogenic climate change.

This work presents the results of long-term complex study of acaridid mites’ fauna and ecology in different biotopes (agricultural and industrial objects) in Zhytomyr Polissia. There were 30 species identified, which belong to five families: Suidasidae, Acaridae, Glycyphagidae, Chortoglyphidae, Aeroglyphidae. The results showed that acarocomplex of industrial objects, like mills, granaries and warehouses, includes the 11 Acaridae species, and that of compound fodder factories — three species. Acarofauna of agricultural objects was shown to consist of 30 species: 21 in barns with animal feed (grains, compound feeds, hay and straw), 12 in outbuildings with livestock and poultry, 9 in beehives, 13 in vegetable storages. The qualitative differences of mentioned acarocomplexes were established, and the factors to possibly influence their dynamics were discussed.

This study was conducted on mosquito larvae (Diptera, Culicidae) in Tarhuna, Libya during the period from January 2018 to December 2018. It aimed to determine the species diversity of mosquitos’ larvae in Tarhuna. Mosquito larvae were collected by dipper 400 ml from eight water locations (four permanent and four temporary water locations). 4,877 larvae were collected, 3,162 from the permanent aquatic locations and 1,715 larvae from the temporary locations. Seven species of mosquito larvae were recorded: Culiseta longiareolata, Culex perexiguus, Culex theileri, Culex laticinctus, Culex pipiens, Culex quinquefasciatus and Anopheles sergentii. Cs. longiareolata was the most abundant species of mosquito larva in both permanent and temporary locations. There were temporal differences in the number of larvae of collected species among months. The results of this study showed that these species were recorded for the first time in Tarhuna and some of them are vectors for some diseases.

Recent Georgia’s fish fauna includes four Capoeta species: C. capoeta (Kura River basin), C. kaput (Araxes River and its left tributaries, the Akhuryan and Mezamor rivers), C. sieboldii (East and South–East Black Sea river basins), and C. banarescuii (Chorokh River basin). Based on morphological data analysis new species of the genus Capoeta — C. svanetica sp. n. is described. It is more similar to the Capoeta damascina complex group (Anatolian–Iranian group) which also includes C. banarescui, C. baliki, and C. sieboldii spread at East and South-East Black Sea coastal rivers. The Anatolian–Iranian group, also known as small-scales species group well distinguished from Aral-Caspian species (C. capoeta and C. kaput in Georgia) by highest scales number in lateral line. C. svanetica sp. n. is distinguished from other Capoeta species of Black Sea basin rivers in Georgia and adjacent waters by combination of characters: two pairs of barbels are present (C. sieboldii and C. oguzelii have one barbels pair); no spots on the body (C. oguzelii has small black spots); lower lip has keratinised edge without fringe (C. sieboldii and C. oguzelii are characterized by fringed lips); scales small, 70–74 total lateral line scales (in C. sieboldii only 52–60 scales); 10–12 scale rows above lateral line (C. banarescui, C. baliki and C. oguzelii have more than 12 scale rows) and 7–8 scale rows below lateral line (C. baliki and C. oguzelii have more than 10 scale rows); 12–15 gill rakers on the first gill arch (C. sieboldii and C. baliki have more then 16); last unbranched fin ray soft, serrae number on it is 7–9 in adult and 0 in juvenile samples (all other Capoeta species of Black Sea basin rivers have well ossified last unbranched ray with high serrae number); anal fin base length is only 7.4–9.4 % of SL (more shorter than C. banarescui, C. baliki and also C. tinca); as well as mouth width (25.4–29.4 % of HL); eye diameter (19.0–28.7 % of HL) is biggest than same in C. banarescui, C. baliki and also C. tinca.

Dice snakes can be a paratenic host for a stage IV of Eustrongylides excisus, Jägerskiöld, 1909 larva due to specific diet of the snakes. The infection rate of E. excisus in Natrix tessellata (Laurenti, 1768) was studied in the basin of the middle and the lower Dnipro River in 2013–2017. We searched for nematodes in snakes from four sites: Prydniprovska Thermal Power Station, Majorova Balka, Zaporizhzhia; National Nature Park Velykyi Luh. The snakes from all studied areas had high prevalence of infection (more than 90 %). The lowest level of intensity (2.50 ± 0.60) and abundance (2.27 ± 0.58) were in ecosystems near Prydniprovska ТPP. There was no significant difference between infection parameters in snakes from other groups. Capsules with larva localized in the gastrointestinal tract, liver, muscles, and lung. The most infected organ was the liver, statistical analysis showed significant differences with other organs. The lowest infection was found in the lung. Environmental pollution of the Dnipro River waters with pesticides and other pollutants accompanied by a climate change may influence on the E. excisus life cycle that needs additional studies.

The diet of the Austral Pygmy Owl, Glaucidium nana, a small raptor, was studied by pellet analysis. During fall of 2020, 52 pellets were collected in a peri-urban protected area. Amongst 122 prey items, Muridae, represented exclusively by the alien species Rattus rattus and Rattus norvegicus, made up 35.24 % by number and 67.1 % of the biomass, followed by native Cricetidae, at a 37.69 % by number and 17.9 % by biomass. In the last place in relative frequency were birds and arthropods. The biomass contribution was unequal among the different prey, being the alien prey the group with the highest profit. The role of the landscape in the composition of prey in the observed trophic spectrum is discussed.
