In addition to a previously published study about Siberian Colletes species, we here further report on poorly known species. Twenty six species are currently known from Siberia with C. cinerascens Morawitz 1893, C. kaszabi Kuhlmann 2002, and C. ebmeri Kuhlmann 2002 found in Russia for the first time and C. wacki Kuhlmann 2002 is newly recorded from the Asian part of Russia. The male of C. wacki is here described for the first time and a lectotype designated for the closely related C. conradti Noskiewicz 1936 to clarify the taxonomy of this group. Colletes uralensis Noskiewicz 1936 was erroneously recorded from Russia and is removed from the list of Russian species. Images and updated distribution maps are provided for the closely related C. kaszabi and C. uralensis as well as for C. conradti and C. wacki to facilitate their identification. An updated checklist of the 42 species of Colletes so far known from Russia is provided.
As a supplement to a previously published study on Siberian Hylaeus species, we here report further records of twenty six rarely collected and little known species. Thirty two species are currently known from Siberia, including Hylaeus dorni Dathe, 1986, H. gredleri Förster, 1871, H. hungaricus (Alfken, 1905), H. moricei (Friese, 1898), H. nimbatus Dathe, 1986, H. oehlkei Dathe, 2010 and H. stubbei Dathe, 1986, which are reported from Russia for the first time, and H. brevicornis Nylander, 1852, H. communis Nylander, 1852, H. pfankuchi (Alfken, 1919) and H. styriacus Förster, 1871, which are newly recorded from Siberia. Hylaeus (Hylaeus) pesenkoi Proshchalykin & Dathe, sp. nov. is described as new from Siberia (Altai Republic and Tyva Republic) and neighbouring Mongolia (Khovd and Govi-Altai Aimags). The females of H. dorni Dathe, 1986 and H. oehlkei Dathe, 2010 are described for the first time; H. peregrinus Dathe, 1986 was recognised as the female of H. stubbei Dathe, 1986 and is treated as a new synonym.
Aerial surveys are often used to monitor wildlife and fish populations, but rarely are the effects on animal behavior documented. For over 30 years, the Kodiak National Wildlife Refuge has conducted low-altitude aerial surveys to assess Kodiak brown bear (Ursus arctos middendorffi) space use and demographic composition when bears are seasonally congregated near salmon spawning streams in southwestern Kodiak Island, Alaska. Salmon (Oncorhynchus spp.) are an important bear food and salmon runs are brief, so decreases in time spent fishing for salmon may reduce salmon consumption by bears. The goal of this study was to apply different and complementary field methods to evaluate the response of bears to these aerial surveys. Ground-based counts at one stream indicated 62% of bears departed the 200m-wide survey zone in response to aerial surveys, but bear counts returned to pre-survey abundance after only three hours. Although this effect was brief, survey flights occurred during the hours of peak daily bear activity (morning and evening), so the three-hour disruption appeared to result in a 25% decline in cumulative daily detections by 38 time-lapse cameras deployed along 10 salmon streams. Bear responses varied by sex-male bears were much more likely than female bears (with or without cubs) to depart streams and female bears with GPS collars did not move from streams following surveys. Although bears displaced by aerial surveys may consume fewer salmon, the actual effect on their fitness depends on whether they compensate by foraging at other times or by switching to other nutritious resources. Data from complementary sources allows managers to more robustly understand the impacts of surveys and whether their benefits are justified. Similar assessments should be made on alternative techniques such as Unmanned Aerial Vehicles and non-invasive sampling to determine whether they supply equivalent data while limiting bear disturbance.
All stages and the ecology of the Southern Palaearctic Palpomyia schmidti collected from the vicinity of the saline Lake Elton in Russia are described and illustrated. The morphology of larvae and pupae as well as the detailed ecology of the larvae are described for the first time. P. schmidti is a halobiontic biting midge, widely distributed in the steppes and deserts of the Palaearctic region. It is proposed that the Palpomyia schmidti group should include five Holarctic species. P. downesi Grogan & Wirth, 1979 from north-western North America is recognized as a new junior synonym of the Eastern Palaearctic P. tuvae Remm, 1972. New synonymy.
We provide a list of the species of the family Haemogamasidae Oudemans, 1926 living in Asiatic Russia, with data on their synonymy, distribution, and relationships with mammal hosts. In total, 23 species of mites distributed between two genera (Eulaelaps Berlese, 1903, and Haemogamasus Berlese, 1889) are covered.
Twenty-nine species of mites of the family Laelapidae s. str. have been recorded as associated with small mammals (rodents, insectivores) in Asiatic Russia (Siberia and the Russian Far East). These species belong to two subfamilies (Laelapinae, Myonyssinae) and six genera: Androlaelaps Berlese, 1903, Dipolaelaps Zemskaya & Piontkovskaya, 1960, Laelaps C.L. Koch, 1836, Hyperlaelaps Zakhvatkin, 1948, Myonyssus Tiraboschi, 1904, Oryctolaelaps Lange, 1955. A list of the species, with data on synonymy, geographic ranges, and relationships with mammal hosts is provided. Some considerations concerning patterns of distribution of the parasitic Laelaptidae of Asiatic Russia are presented as well as their classifications from the point of view of known host association records.
Records of leafroller moths (Tortricidae) from the Rostov-on-Don province of southern Russia are presented based on 10 years of field work (2005-2014). The list includes 91 species from 43 collecting sites; 80 species are recorded from the region for the first time. Compared to other well-surveyed, adjacent areas, the tortricid fauna is considerably more depauperate, and this may be explained in part by the predominance of steppe vegetation.
This paper is the third monograph of the series that describes the global records of limno-terrestrial water bears (Tardigrada). Here, we provide a comprehensive list of non-marine tardigrades recorded from the North America, providing an updated and revised taxonomy accompanied by geographic co-ordinates, habitat, and biogeographic comments. It is hoped this work will serve as a reference point and background for further zoogeographical and taxonomical studies.
Mosquitoes (Diptera: Culicidae) were collected throughout Finland between 2013 and 2018 to determine species distributions. During the course of molecular identifications of specimens belonging to the Anopheles maculipennis complex, ribosomal internal transcribed spacer 2 sequences and link-reared specimens revealed the presence of Anopheles daciae Linton, Nicolescu & Harbach (n = 37), a new country record, as well as Anopheles messeae Falleroni (n = 19) in the collections. Although the sample size is low, distinctions are apparent in the distributions of these two species, with An. daciae present in south-eastern and central Finland, including the regions of Kanta-Häme, Pirkanmaa, Pohjois-Pohjanmaa, Päijät-Häme and Satakunta, and An. messeae present in the southern and south-eastern regions of Åland (Ahvenanmaa), Etelä-Savo, Kanta-Häme, Kymenlaakso, Päijät-Häme, Satakunta, Uusimaa and Varsinais-Suomi. All reports of An. messeae in Finland prior to 2018 should therefore be recognized as potentially being either An. messeae or An. daciae. Because these species are potential vectors of malarial protozoa, it is important to have full knowledge of their distributions across Europe, particularly in the face of climate warming.
