Recent research suggests that alluvial aquifers in southern and eastern Australia may contain a diverse subterranean aquatic fauna (i.e. stygofauna). However, to date only a limited number of alluvial aquifers have been studied and little molecular data are available to assess species-level diversity and spatial patterns of genetic variation within stygofaunal species. In this paper, we present the initial results of a stygofaunal survey of the Burdekin River alluvial aquifer in Queensland, extending the northern range of alluvial aquifers along the east coast of Australia that have been investigated. The survey resulted in the collection of bathynellid stygofauna (Syncarida: Bathynellacea) and genetic analyses were conducted to determine species level diversity using the mitochondrial cytochrome oxidase subunit I (COI) gene. We further investigated the phylogenetic relationships of the species with bathynellids from western and southern Australia to assess the generic status of species. Four highly divergent COI lineages within the Parabathynellidae and one lineage within the Bathynellidae were found. These lineages did not group within any described genera, and phylogenetic analyses indicated that both local radiations and the retention of a lineage that was more apical in the genealogy account for the diversity within the Parabathynellidae in the Burdekin River alluvial aquifer. Most COI lineages were sampled from only a single bore, although one taxon within the Parabathynellidae was found to be more widespread in the aquifer. Haplotypes within this taxon were not shared among bores (ΦST = 0.603, P < 0.001). Overall, the high species diversity for bathynellaceans from an alluvial aquifer reported here, and surveys of bathynellaceans in several other alluvial systems in south-eastern Australia, suggests that groundwater ecosystems of eastern Australia may contain high stygofaunal diversity by Australian and world standards, particularly at the generic level for parabathynellids.

Abstract Mosquito larvae play an essential role in the ecological, and many of them can spread human and animal diseases, including in Macaca fascicularis. Information on mosquito species and their habitats can provide an overview of the role of mosquitoes in the spread of vector-borne diseases in M. fascicularis captivity area. This study aimed to identify species diversity of mosquito larvae, species affinity and association, and the larval breeding sites around M. fascicularis captivity area in Bogor, West Java. Mosquito larvae were collected from 102 sites using a 350 ml dipper. Mosquito larvae that were successfully collected consisted of 11 species; Aedes albopictus, Ae. aegypti, Armigeres subalbatus, Anopheles aconitus, An. kochi, An. vagus, Culex fuscocephala, Cx. pseudovishnui, Cx. tritaeniorhyncus, Cx. quinquefasciatus, and Cx. vishnui. Co-occurrence in mosquito larvae as many as 13 compositions, with the highest co-occurrence in Ae. albopictus and Cx. quinquefasciatus that was 11 times. There were seven types breeding sites for the larval mosquitoes, i.e containers, ditches, creeks, ponds, artificial ponds, groundwater puddles, and rice fields. We conclude the existence of mosquito larvae and the availability of their breeding site in M. fascicularis captivity area can be a potential transmission of pathogens between mosquitoes and hosts

It has been installed that the species richness of the blackflies of the north-eastern macroslope of the Ukrainian Carpathians counts 38 species of 2 genera: Prosimulium Roubaud, 1906 (2 species) and Simulium Latreille, 1802 (36 species). 20 species develop in the streams (Simpson's species diversity index (Іs) equals to 0,22), and 26 species develop in the rivers (Іs – 0,10). There are 8 common species of Simuliidae for both types of watercourses (similarity index by Czekanowski/Sørensen (І) is 0,26). 12 species of blackflies develop only in the streams, and 18 species develop only in the rivers. S. trifasciatum Curtis, 1839, S. reptanoides Carlsson, 1962, S. ornatum Meigen, 1818 and S. intermedium Roubaud, 1906 dominate in the hydrobiocenoses of the north-eastern macroslope of the Ukrainian Carpathians. S. trifasciatum and S. ornatum are widespread. It has been discovered that Simuliidae fauna of main altitudinal zonal plant groups of the region differs in composition and quantitative correlation of species. S. intermedium, S. ornatum, S. reptans Linnaeus, 1758 and S. trifasciatum are eurytopic. In the hydrobiocenoses of the district of beech forests has been registered 31 species (Is – 0.09), and in the watercourses of the district of spruce mountain Carpathian forests has been registered 24 species (Is – 0.18). It has been found out that with the decrease of height in the district of the beech forests, the value of Simpson's species diversity index decreases from 0.16 (20 species) in the subdistrict of the dark-coniferous-beech watershed forests to 0.11 (21 species) in the subdistrict of fir-beech and beech-fir precarpathian forests.

Abstract Dirofilaria immitis (Leidy, 1856) and Dirofilaria repens (Railliet & Henry, 1911) are mosquito-borne filarial nematodes that primarily affect dogs, causing heartworm disease and subcutaneous dirofilariosis. The canine heartworm is reported in different provinces in Turkey. However, studies about the transmitting mosquito species are limited. Hence, this study aimed to investigate potential vectors of D. immitis and D. repens in Aras Valley, Turkey. In total, 17,995 female mosquitoes were collected from eight villages during three mosquito seasons (2012–2014) in Aras Valley, located in north-eastern Turkey. A total of 1,054 DNA pools (527 abdomen and 527 head-thorax) were tested with Dirofilaria primers by multiplex-polymerase chain reaction (PCR). Aedes caspius was the most abundant species in collection sites with 90%; this was followed by Culex theileri Theobald, 1903 (Diptera: Culicidae) (7.31%), Anopheles maculipennis Meigen 1818 (Diptera: Culicidae) (1.28%), Culex pipiens Linnaeus, 1758 (Diptera: Culicidae) (0.43%), (Anopheles) hyrcanus (Pallas, 1771) (Diptera: Culicidae) (0.37%), Aedes vexans (Meigen, 1830) (Diptera: Culicidae) (0.25%), and Culiseta annulata Schrank, 1776 (Diptera:Culicidae) (0.02%). Dirofilaria immitis and D. repens were detected in mosquito pools from five villages. The total Dirofilaria spp. estimated infection rate was 1.33%. The highest estimated infection rate was found in Ae. vexans (6.66%) and the lowest was in Ae. caspius (1.26%). The results show that An. maculipennis sl, Ae. caspius, Ae. vexans, Cx. theileri and Cx. pipiens are potential vectors of D. immitis and D. repens with DNA in head-thorax pools; An. hyrcanus is also a likely vector, but Dirofilaria DNA was found only in abdomen pools for the study area. This study revealed new potential vector species for D. immitis. Mosquitoes with natural infections of D. repens were reported for the first time in Turkey.

The spatial and species structure of fucus algae communities in littoral phytocenoses of Eastern Murmansk is studied. This is the North-Eastern border of Fucus communities. 87 species of macrophyte algae were identified in the communities. The variation of species diversity as an indicator of community structure is determined depending on the leading abiotic factors – salinity, surf content, and substrate type. The species diversity of macrophyte algae in the littoral of the Eastern Murmansk is determined primarily by surf activity. Under similar hydrological conditions, soil features determine the density of thickets and, consequently, the number of species found in a single sample. Salinity fluctuations at which it drops below 15‰ are critical for most species and fundamentally change the structure of communities. The highest values of the indices of species diversity were observed in the littoral areas of the coast that are poorly protected from the surf.

Objective of research: To study the species diversity of ticks in the north — eastern part of Uzbekistan: fauna, distribution patterns and ecology. Materials and methods: Research samples were collected with the use of common parasitological methods [2, 3, 4]. Host animals were examined once a decade by collecting parasites from certain groups of farm and wild animals. Results and discussion: 13 species of 6 tick genera discovered during the research period on the territory of the north — eastern Uzbekistan: Ixodes persulcatus, I. redikorzevi, I. crenulatus, Haemaphusalis caucasica, Boophilus calcaratus, Dermacentor pictus, D. daghestanicus, D. pavlovskyi, Rhipicephalis turanicus, H. asiaticum, H. detritum, H. anatolicum, H. plumbeum turanikum. Species B. salcaratus, H. asiaticum are distributed in all survey areas what confirms their high ecological flexibility. The extensity of infection of livestock with ticks is rather high — 51.3 — 52.3%. The infestation of synanthropic and wild animals ranged from 37.0 to 40.0%.
