Abstract Freshwater mussels (Unionida) are one of the most imperiled animal groups worldwide, revealing fastest rates extinction. Habitat degradation, river pollution and climate change primary causes global decline. However, biological threats for freshwater still poorly known. Here, we describe a diverse ecological group leeches (Hirudinea: Glossiphoniidae) inhabiting mantle cavity mussels. So far, examples mussel-associated leech species recorded from East Asia, Southeast India Nepal,...
The High Arctic bumble bee fauna is rather poorly known, while a growing body of recent molecular research indicates that several species may represent endemic lineages with restricted ranges. Such local endemics are in need special conservation efforts because the increasing anthropogenic pressure and climate changes. Here, we re-examine taxonomic biogeographic affinities bees from Novaya Zemlya using historical samples recently collected materials (1895-1925 vs. 2015-2017). Three inhabit...
Abstract The subfamily Sphaeriinae is a diverse and ecologically significant group of freshwater invertebrates, playing keystone role in the energy flow nutrient cycling aquatic ecosystems. Despite long history its study, taxonomic structure species content this are matter ongoing disputes between malacologists. We clarify taxonomy, distribution, evolutionary biogeography around world based on largest dataset DNA sequences these clams ever accumulated, which includes data specimens collected...
Trace elements in freshwater bivalve shells are widely used for reconstructing long-term changes the riverine environments. However, Northern Eurasian regions, notably European Russian North, susceptible to strong environmental impact via both local pollution and climate warming, poorly studied. This work reports new data on trace accumulation by widespread species of mussels Unio spp. Anodonta anatina Severnaya Dvina Onega River Basin, two largest subarctic river basins Northeastern Europe....
Here we describe a new subgenus and three species of parasitic water mites in the genus Unionicola (Acari: Hydrachnidia) from Myanmar: Myanmaratax subgen. nov., (Myanmaratax) savadiensis sp. nov. (hosts: Lamellidens L. generosus), U. (My.) generosa (the same hosts), trapezidenssp. Trapezidens dolichorhynchus T. angustior). These taxa were identified based on two-gene phylogenetic analysis (COI + 28S), which also confirms division into numerous subgenera. The are cryptic species,...
Background insect herbivory, i.e. the minor but chronic plant damage caused by insects, is usually considered 'negligible' for plants when compared with severe defoliation associated forest pest outbreaks. We experimentally tested hypothesis that impacts of background herbivory on tree growth and mortality accumulate over years, resulting in much larger effects than assumed. In boreal taiga forests near Arkhangelsk (Northern Russia), application insecticide at 10-day intervals four seasons...
Norwegian Lemming Lemmus lemmus is a remarkable population cycling species having number of aposematic traits in coloration and behavior. This was thought to be the only mammal endemic Fennoscandia. Here, we report on discovery distinct lineage this from Novaya Zemlya. described here as new subspecies chernovi ssp. nov. that morphologically differs nominate by cryptic coloration. Our time-calibrated phylogeny revealed insular isolated there since Eemian interglacial (mean age 93 Ka). Hence,...
The geographic patterns of genetic and morphological variability in ground beetles were examined throughout Northern Eurasia North America using the most abundant circumpolar tundra subspecies, Pterostichus (Cryobius) brevicornis (Kirby, 1837), as a model. Phylogenetic structure was assessed on basis Bayesian approach two DNA markers (partial sequences COI 28S rRNA genes), while phylogeographic population diversity estimated gene only. Morphological analysed elliptical Fourier coefficients...
Subgenus Cryobius is one of the most numerous among megafauna tundra soils, but studies on its species distribution, taxonomy, and ecology are lacking. Phylogeny phylogeography reconstructions insects with taxonomic complexity have become possible using an integrative approach. Here, we report that specimens Pterostichus (Cryobius) mandibularoides, described from North America, were detected in Eurasia. Thus, this has a trans-Beringian range high distributions as well disjunctive part...
Latitudinal gradients allow insights into the factors that shape ecosystem structure and delimit processes, particularly climate. We asked whether biomass diversity of soil macrofauna in boreal forests change systematically along a latitudinal gradient spanning from 60° N to 69° N. Invertebrates (3697 individuals) were extracted 400 samples (20 × 20 cm, 30 cm depth) collected at ten sites 2015–2016 then weighed identified. discovered 265 species living on surface; their average density was...
ABSTRACT Aim Long‐standing theory predicts that the intensity of biotic interactions increases from high to low latitudes. Studies addressing geographic variation in predation on insect prey have often relied models, which lack many characteristics live prey. Our goals were explore global latitudinal patterns predator attack rates standardised and compare insects with those plasticine models. Location Global forested areas. Time Period 2021–2023. Major Taxa Arthropods, birds. Methods We...
The bumblebee fauna of the Southern Taymyr region, northern Siberia, is represented by 10 species, i.e., Bombus consobrinus , B. flavidus lapponicus hypnorum jonellus cingulatus balteatus pyrrhopygus hyperboreus and cryptarum . During field research for this study, 7 species on Putorana Plateau (or Mountains, northwestern edge Central Siberian Plateau) 6 near Dudinka Town were observed was found first time Plateau. To date, known only in southern central parts Krasnoyarsk Krai. Regarding...
The bumble bee fauna of the Russian Arctic is rather poorly known. Kolguev Island, a remote insular territory in Barents Sea, one deficiently studied areas. In this study, material on Kolguev's bees re-examined, phylogeographic data analysed, putative scenarios explaining origin island discussed, and biology phenology these populations described. Five species, i.e., Bombusflavidus, B.lapponicus, B.jonellus, B.pyrrhopygus, B.balteatus, were recorded island. All species are widespread...
This study (1) displays markings pattern of male and female specimens Arctia tundrana from various parts its broad range; (2) illustrates a paratype specimen this species with genitalia aedeagus; (3) presents few additional occurrences A. supplementing the data set published in our earlier paper (Bolotov et al. 2015); (4) provides an updated map species’ occurrences; (5) discusses imaginal phenology based on long-term occurrence data.
In this study, we present an announcement of Novaya Zemlya Collared Lemming Dicrostonyx torquatus ungulatus (von Baer, 1841) complete mitogenome. This rodent was described historically as Arctic subspecies endemic to (Arctic Russia) but its taxonomic status unclear due the lack available molecular data. Based on a comprehensive mitogenomic phylogeny Lemming, show that insular population shares highly divergent mtDNA sequence (total length 16,341 bp). Hence, it should be considered valid...
In this study, we synonymized Pterostichus (Cryobius) kolymensis Erjiomin, 1998 with P. (C.) mandibularoides Ball, 1966 by an integrative approach. Geometric morphometric analysis revealed no obvious differences in the shape of pronotum and median lobe aedeagus between kolymensis. According to DNA analysis, all examined specimens belong 11 unique haplotypes COI from northern Canada, USA (Alaska) Russia (Yakutia, Chukotka Wrangel Island) 1 haplotype 28S rDNA Eurasia (Russia). The...
