Checklist of the Ichneumonidae (Insecta, Hymenoptera) of Ukraine.

This paper provides the first summary on the distribution of the Ukrainian Ichneumonidae based on both literature and collection resources. The checklist contains 1,840 species, of which 42 are first records from Ukraine and Apoclima rossicum Humala, 2007 is the first record from Western Palaearctic. The condition and representativeness of the national collection of Darwin wasps and prospective directions for further studies are discussed.

RARE AND ENDANGERED ROVE BEETLES OF UKRAINE: EMUS HIRTUS LINNAEUS, 1758 (COLEOPTERA: STAPHYLINIDAE).

In Ukraine, Emus hirtus Linnaeus, 1758 (Coleoptera: Staphylinidae) is protected by the national Red Book. The species is widely distributed in all natural zones of the country but occurs sporadically. Almost everywhere in Ukraine E.

Revision of the Aspistomella group of genera (Diptera: Ulidiidae: Pterocallinae: Lipsanini).

Twenty-three species of the genera Aspistomella Hendel, 1909, Polyteloptera Hendel, 1909, and Ulivellia Speiser, 1929 occurring in South America (Colombia, Peru, Bolivia, and Brazil) form a monophyletic lineage sharing certain combinations of plesiomorphies and apomorphies with similar larval biology. The name Aspistomella Hendel, 1909 is a new senior subjective synonym of Paraphyola Hendel, 1909. The group of genera is extended by the addition of six known species, Aspistomella angustifrons (Hendel, 1909) comb.

Descriptions of two new species of Bactrocera Macquart (Diptera: Tephritidae: Dacinae: Dacini) from the Philippines with distinct orange medial stripes on the scutum.

Two previously undescribed species of Bactrocera Macquart with distinct orange medial stripes on the scutum were collected in multi-lure traps baited with cue-lure during a fruit fly survey carried out in the Philippines in 2019. We describe Bactrocera youngi sp. n.

Helminth Parasites of Invasive Freshwater Fish in Lithuania.

Freshwater ecosystems in Lithuania are threatened by the introduction of invasive fish species including , , , and . Data on helminth parasites of these fishes have not been comprehensively studied, with only two reports on parasites of from the Curonian Lagoon and Baltic Sea, Lithuania. We examined 278 fish individuals representing 4 invasive species from 13 waterbodies.

Wolbachia in Antarctic terrestrial invertebrates: Absent or undiscovered?

Interactions between a host organism and its associated microbiota, including symbiotic bacteria, play a crucial role in host adaptation to changing environmental conditions. Antarctica provides a unique environment for the establishment and maintenance of symbiotic relationships. One of the most extensively studied symbiotic bacteria in invertebrates is Wolbachia pipientis, which is associated with a wide variety of invertebrates.

Contribution to host diversity, genetic diversion, and epidemiology of Trichinella pseudospiralis in Slovakia, central Europe.

Trichinella pseudospiralis belongs to the non-encapsulated clade of the genus and its epidemiology is influenced by various biotic and abiotic factors. The role of different animal species in the spread and epidemiology of the parasite is still not well understood and further research is needed in the areas where its occurrence has been recorded. In Slovakia, T.

Micromammals as a reservoir for the zoonotic nematode (syn. ) in recreational areas of Slovakia.

The hepatic nematode is a zoonotic parasite primarily parasitising small mammals, but it can infect a wide range of mammal species, including humans. Due to its specific life cycle and transmission pattern, it is one of the least studied helminths in the world. The only documented findings of from Slovakia (former Czechoslovakia) come from the 60s and 70s of the 20th Century, including nine human cases of the infection reported .

Relaxed selection in evolution of genes regulating limb development gives clue to variation in forelimb morphology of cetaceans and other mammals.

Cetaceans have evolved unique limb structures, such as flippers, due to genetic changes during their transition to aquatic life. However, the full understanding of the genetic and evolutionary mechanisms behind these changes is still developing. By examining 25 limb-related protein-coding genes across various mammalian species, we compared genetic changes between aquatic mammals, like whales, and other mammals with unique limb structures such as bats, rodents and elephants.

Migratory birds modulate niche tradeoffs in rhythm with seasons and life history.

Movement is a key means by which animals cope with variable environments. As they move, animals construct individual niches composed of the environmental conditions they experience. Niche axes may vary over time and covary with one another as animals make tradeoffs between competing needs.

Effectiveness of benzimidazole treatments against Haemonchus contortus in sheep and goats - Do they produce similar responses?

The primary aim of this study was to compare the in vivo responses to orally administered doses of albendazole (5 mg/kg body weight) between experimentally infected sheep and goats. Fifty-four Improved Valachian lambs and 54 Saanen goat kids were split into six groups of nine animals. The sheep and goats were infected with larvae of the gastrointestinal nematode parasite Haemonchus contortus containing 10, 20, 30, 40, 60, and 80 % of the isotype-1 β-tubulin gene codon 200 alleles previously shown to be associated with benzimidazole (BZ)-resistance.

Present and future distribution of the European pond turtle versus seven exotic freshwater turtles, with a focus on Eastern Europe.

Freshwater turtles are often used as terrarium pets, especially juveniles of exotic species. At the adult stage they are often released by their owners into the wild despite their high invasion potential. In Europe these thermophilic potentially invasive alien species occupy the habitats of the native European pond turtle Emys orbicularis (Linnaeus, 1758), with new records from the wild being made specifically in Eastern Europe (Latvia and Ukraine) during recent decades.

Network analysis to reveal the most commonly detected compounds in predator-prey pairs in freshwater and marine mammals and fish in Europe.

Marine and freshwater mammalian predators and fish samples, retrieved from environmental specimen banks (ESBs), natural history museum (NHMs) and other scientific collections, were analysed by LIFE APEX partners for a wide range of legacy and emerging contaminants (2545 in total). Network analysis was used to visualize the chemical occurrence data and reveal the predominant chemical mixtures for the freshwater and marine environments. For this purpose, a web tool was created to explore these chemical mixtures in predator-prey pairs.

DESCRIPTIONS AND PHYLOGENETIC AFFINITIES OF TWO NEW SPECIES OF RHABDIAS STILES AND HASSALL, 1905 (NEMATODA: RHABDIASIDAE) FROM NORTH AMERICAN FROGS: ARE WE STILL ONLY SCRATCHING THE SURFACE?

Two new species of lung-dwelling nematodes are described from North American frogs: Rhabdias aurorae n. sp. from Rana aurora and Rhabdias conni n.

Countrywide screening supports model-based predictions of the distribution of Batrachochytrium dendrobatidis in Ukraine.

The chytrid Batrachochytrium dendrobatidis (Bd) is a widespread fungus causing amphibian declines across the globe. Although data on Bd occurrence in Eastern Europe are scarce, a recent species distribution model (SDM) for Bd reported that western and north-western parts of Ukraine are highly suitable to the pathogen. We verified the SDM-predicted range of Bd in Ukraine by sampling amphibians across the country and screening for Bd using qPCR.

Cretaceous crown male ant reveals the rise of modern lineages.

Most described Mesozoic ants belong to stem groups that existed only during the Cretaceous period. Previously, the earliest known crown ants were dated to the Turonian (Late Cretaceous, ca. 94-90 million years ago (Ma)) deposits found in the USA, Kazakhstan, and Botswana.
