Among the gastrointestinal parasitoses, fascioliasis is one of the most common diseases in ruminants. Fasciola spp. is recorded on five continents of the globe, in more than 50 countries. The parasitizing trematode causes economic losses associated with a decrease in milk yield, body weight, and culling of affected carcasses and organs. In this study, we aimed to quantify the prevalence of fascioliasis among ruminants (cattle, sheep and goats) of the world in terms of the odds ratio according to the Mantel–Haenszel test (M–H). Online databases in English, Russian and Ukrainian languages were searched for publications from January 2002 to September 2020. This meta-analysis included 42 studies with ruminant hosts. Data on the spread of fascioliasis were collected from different continents of the globe: North and South America, Europe, Asia and Africa. The results of the study found that the overall prevalence of fascioliasis in cattle was 6.41 %, while in small ruminants it was only 2.03 %. The disease in cattle was recorded 1.48 times more often than in sheep and goats. Egger’s regression test revealed no significant publication bias (P = 0.265). The results of the meta-analysis confirm that the causative agent of fascioliasis circulates mainly in the emerging countries. The updated data on fascioliasis will expand the screening strategy to maintain the health of farm ruminants and reduce economic losses.

Data about meiobenthic ostracodes species on the different substrates of Zmiiniy Island nearshore water area are presented. The density and biomass means of the ostracodes were higher on the algal substrates (on Laurencia paniculata made up 41931 ± 12689 ind.·m-2 and 400.56 ± 125.65 mg·m-2 respectively). In the current study for the first time 13 ostracodes species were found, most of which are common in all types of substrate. The dominant species were Loxoconcha pontica Klie, 1937, Paradoxostoma intermedium Müller, 1894, Xestoleberis cornelii Caraion, 1963 and Xestoleberis decipiens (Müller, 1894). All of them are common species in the north-western Black Sea. Non-metric multidimensional scaling (nMDS) analysis of ostracodes species abundance shown that the samples of sandy-shells bottom differed significantly from algal and mussel substrates. According to the cluster analysis sand-shells bottom samples on almost 80 % differed from hard substrates.

Over the period 2007–2019, the author’s censuses of steppe birds in the Azov-Black Sea dry-steppe enclave determined five species as dominants and co-dominants by their abundance. Thus, Melanocorypha calandra dominates throughout the whole area, Emberiza calandra dominates in 4 subregions and co-dominates in 5 subregions, Motacilla feldegg, Emberiza hortulana, Anthus campestris, Alauda arvensis dominate in 1 subregion and do not dominate or co-dominate in 1–4 subregions. There is a general increasing trend in the total abundance of steppe birds and the number of their rare breeding species from north-west to south-east, whereas the number of their dominants and co-dominants grows in the opposite direction. According to the list, the correlation between the dominants/co-dominants and the number of rare breeding steppe species, it was revealed that the most valuable for the support of the steppe bird populations are subregions with the largest areas of virgin steppes (the Kerch Peninsula, Western and Central Crimea). The least important are the subregions with the highest degree of anthropogenic transformation (northern part of the Syvash region, western part of the Black Sea region) and the Lower Dnipro wetlands. Therefore, it is a high abundance of steppe birds and the maximum number of rare steppe species which should be a specific ornithological indicator of the status of zonal landscapes in the dry steppe zone (especially within protected natural areas of Ukraine) rather than general avian species diversity including introduced, invasive species, synanthropes, etc.

The retractable proboscis of acanthocephalans is equipped with hooks for attachment to the intestine of the definitive host. Throughout their evolutionary history, acanthocephalans have developed a variety of ways to maximize their anchoring to host gut and to avoid dislodgement. Hooks vary in their size and shape along the longitudinal axis of the proboscis, texture, structure, and hardness as well as in their contribution to the absorption of nutrients. Hooks also vary in their chemical composition, especially calcium, phosphorus, and sulfur, contributing to their hardness. Hook roots are paramount in anchoring them to the cuticular and subcuticular layers of the proboscis. Roots vary in size and shape and are often simple and directed posteriorly but often have anterior manubria or may be vestigial or absent especially posteriorly. The core layer of roots is usually continuous with that of the hook. Hooks often, but not always, maintain a similar pattern in families. Because of the inconsistencies and inadequacies in the description of hooks, especially in line drawings, in various groups of acanthocephalans, we have decided to provide the largest assortment of morphological and anatomical variabilities among the many species that we have studied over the years. We are, thus, reporting the SEM of hooks of 30 selected species of acanthocephalans in 13 families in an attempt to elucidate patterns and trends characteristic of acanthocephalan families.

A total of 38 species of mosquitoes of the Culicidae family of two subfamilies Anophelinae and Culicinae belonging to 6 genera, were identified on the territory of Kharkiv Region from 2009 to 2019. Dirofilaria larvae were found in 932 insects, which was 4.46 % of the surveyed mosquitoes. The prevalence of the infection of female mosquitoes by dirofilaria was 4.46 ± 0.24 %, while the mean intensity of dirofilariae was 5.4 ± 2.1. Infection of mosquitoes with dirofilariae is currently detected in 11 districts of Kharkiv Region and the city of Kharkiv. The infection rate of mosquitoes of the genus Aedes was 3.83 ± 0.63 %, of the genus Culex — 0.75 ± 0.34 %, of the genus Anopheles — 0.12 ± 0.39 %, whereas females of the genera Culiseta, Coquillettidia, and Uranotaenia were uninfected. It was found that in Kharkiv Region there were 2 types of canine dirofilariae — Dirofilaria immitis (Leidy, 1856) and Dirofilaria repens (Railliet & Henry, 1911), with a predominance of Dirofilaria repens. For the period from 2009 to 2019, we examined 378 blood samples from dogs (190 males and 188 females) aged from 8 months to 13 years with suspected dirofilariasis. According to the results of the studies, 140 samples were positive, the prevalence of infection by the larvae of Dirofilaria spp. in blood samples from dogs with suspected dirofilariasis was 37.03 ± 0.12 %, while infection with Dirofilaria immitis was 2.86 ± 0.45 %, and Dirofilaria repens — 97.35 ± 0.24 %. The number of positive samples from mongrel dogs was 42 (30 %). It was found that cats are more often amicrofilariaemic than dogs.

Two new scorpion species are described from Skyros and Andros Islands (Greece), Euscorpius triantisi sp. n. and E. simaiakisi sp. n. respectively, based on morphological and molecular evidence. Identity and level of divergence of these taxa are confirmed by a phylogeny based on multiple DNA markers (Parmakelis et al., 2013 b). Euscorpius triantisi sp. n. forms a sister clade to E. mylonasi Fet et al., 2014 from Euboea; the new species is characterized primarily by higher trichobothrial numbers (Pv = 8 and Pe-et = 6). E. simaiakisi sp. n. forms a sister clade to E. kritscheri Fet et al., 2013 from Tinos; the new species is primarily characterized by lower trichobothrial numbers (Pv = 7 and Pe-et = 5).

Habitat conditions and factors were studied contributing to the spread of I. ricinus over vast territories. There are excellent conditions for the existence of hard ticks in the settlement agglomerations throughout Ukraine: suitable biotopes with expedient litter and a large number of hosts for all stages of development of ticks. The castor bean tick lives in all of Ukraine, adapting its size of idiosome and diapause to changing environmental conditions, and using the ability to parasitize on animals well adapted to urban conditions. I. ricinus prefers urban landscapes in areas with unfavorable environmental conditions. The hiatus in the range of the castor bean tick between the southern mainland of Ukraine and the steppe regions of Crimea may be restored due to global climatic changes.

The current study was conducted in one of the most important water sources in Iraq, the Euphrates river to evaluate the diversity and density of Gastropoda and Bivalvia by using appropriate biodiversity indices. The samples were taken monthly from the river sediments, during the period from 1 July 2018 to 1 June 2019 from 3 stations, the distance between the first and second stations is 5 km and the second and third station is 7 km. The results showed the presence of 9 species, 7 of them belong to the Gastropoda and 2 belong to the Bivalvia. The total number of Mollusca was 2675 ind/m2. The species Melanoides tuberculata (Muller 1774) showed more relative abundance in the Euphrates River during the study period. The highest value for richness was recorded in March at station 3, while the Shannon Wiener diversity index, the results showed that the highest values were in April and May for all sites, and the highest value for eveness was recorded in January at Station 3, while the highest value for dominance was during October at station 3. Moreover, the current study included the monthly measurement of five environmental factors: water temperature, pH, salinity, dissolved oxygen, and organic matter.

Moreover, the current study included the monthly measurement of five environmental factors: water temperature, pH, salinity, dissolved oxygen, and organic matter.","PeriodicalId":36290,"journal":{"name":"Zoodiversity","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67087368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
The paper contains information about 21 cases of abnormal amplexus among anurans (Amphibia) detected on the territory of the Chernivtsi Region, Ukraine. Multiple amplexus, consisting of one female and two or more males, was registered in three species: Bombina variegata, Bufo bufo, Rana temporaria. The author described interspecific amplexus in six cases. Five of them were among anurans (Bufo bufo male × Pelophylax lessonae male, Rana dalmatina males × Rana temporaria female or males, Rana temporaria male × Pelophylax ridibundus female) and one case — among Anura and Caudata (Bombina variegata male × Lissotriton montandoni female).
本文包含了在乌克兰切尔诺夫茨地区境内检测到的21例anurans(两栖类)异常标本的信息。在不同种类的bomina variegata、Bufo Bufo和Rana temporaria中发现了多肢，由1只雌性和2只或2只以上雄性组成。作者描述了6例种间扩增。其中无尾目中有5例(大黄尾目雄性Bufo fo x Pelophylax lessonae雄性，斑尾目雄性Rana x临时无尾目雌性或雄性，临时无尾目雄性Rana x Pelophylax ridibundus雌性)，无尾目和尾目动物中有1例(大黄尾目雄性bomina x Lissotriton montandoni雌性)。
