Cladocerans (Crustacea: Branchiopoda) of Northern Eurasia traditionally belong to the most intensively studied groups freshwater microcrustaceans. However, despite a significant progress in our knowledge different aspects on their biology, some intriguing questions remain unresolved. The hypothesis cladoceran faunas differentiation between western and eastern parts agrees with continental endemism concept. But date few species have been investigated through whole North Eurasian range. Our...
Insufficient attention has been recently paid by the taxonomists to family Bosminidae Baird (Crustacea: Cladocera). Here we describe a new species of Bosmina (Liederobosmina) Brték from high mountain water bodies Colombia which is unique among all bosminids having heavily striated valves. Most probably, this taxon narrow distribution area in Andean mountains. It obvious that highlands must be studied detail, i.e. using molecular methods, and more taxa might detected future.
Daphnia curvirostris species complex is a cladoceran group (Crustacea: Cladocera) with maximum diversity in Eastern Palearctic. To date, several representatives of this are known from the Russian Far East. Here we describe new sinevi water bodies Sakhalin Island. Morphology its parthenogenetic females similar to that D. continental part Asian Eurasia. However, found diagnostic traits sakhalinensis sp.nov. morphology second pecten on postabdominal claw, armature seta 2 exopodite III,...
Abstract The eastern Palaearctic is a centre of diversity for freshwater cladocerans (Crustacea), but little known about the evolution and taxonomy this diversity. Daphnia curvirostris Holarctic species complex that has most its in Palaearctic. We examined phylogeography, rates taxonomic status each clade D. using morphological genetic evidence from four genes. cybertaxonomical supported an clade, with at least (described here as korovchinskyi sp. nov. group) having diagnostic characters....
Detailed study of morphology Alona werestschagini Sinev, 1999 (Crustacea: Cladocera) confirms its affinities with guttata Sars, 1862. A. is the only Arcto-Alpine species among family Chydoridae, distributed along Arctic coast Eurasia and in mountains Central Asia, newer recorded temperate lowlands continent. In our opinion, evolved mountainous regions while spreading to took place Pleistocene.
Enchytraeids, commonly known as potworms, are small oligochaetes found worldwide in various terrestrial, freshwater and marine ecosystems. Despite their crucial role ecosystem functioning, the diversity abundance of Enchytraeidae seldom studied due to labour-intensive process species identification. This study aims address this gap expand knowledge on distribution enchytraeids within Northern Palaearctic Region. The provided dataset represents latest most comprehensive field sampling...
It is widely accepted among the Cladocera (Crustacea) taxonomists that almost all cosmopolitan taxa are represented by some un-revised complexes of cryptic species. But many macro cladocerans still unrevised. The aim this work to analyze taxonomic status Oriental populations genus Bosminopsis Richard, 1895 (Anomopoda: Bosminidae) based on morphological characters. We have studied from India, Myanmar, Cambodia, Thailand, Laos, Vietnam, Philippines, Malaysia and Papua New Guinea concluded...
Water fleas (Crustacea: Cladocera) are among the most intensively studied freshwater invertebrates. However, ecologically important daphniids that live on surface layer (neuston) remain taxonomically confused. Here we attempt to reconcile genetic and morphological information for neustonic genus Scapholeberis Schoedler, 1858 (Cladocera: Daphniidae) present first revision of kingii species group. We analyzed new existing mitochondrial DNA sequences (сytochrome C oxidase subunit I gene region)...
Water fleas (Crustacea: Cladocera) of the Family Bosminidae have been studied since founding paleolimnology and freshwater ecology. However, one species, Bosminopsis deitersi , stands out for its exceptional multicontinental range broad ecological requirements. Here we use an integrated morphological multilocus genetic approach to address species problem in B. . We analyzed 32 populations s. lat. Two nuclear two mitochondrial loci were used carry bGMYC, mPTP STACEY algorithms delimitation....
The aim of this paper is to study the species composition, structure and seasonal dynamics cladoceran fauna associations in inland water bodies Jeju Island (Republic Korea). Only 47 taxa were found 199 samples. Such faunal paucity could be explained by existence only a few types aquatic environments on as compared continental China Far East Russia, with their great diversity types. We have demonstrated high significance tropical Jeju. Our data confirm faunistic changes waters Island. rate...
The Far East of Russia is a region where boreal and tropical faunas mix; it also zone cladoceran endemism. present study aimed to compare set microcrustacean (Cladocera Copepoda) associations in three large lakes the Russian East: Khanka, Bolon, Chukchagir. microcrustaceans were identified based on function discrete hypergeometric distribution. Many 108 taxa found here unaffiliated with an association. Interestingly, portion involved “not involved” species differed among geographic faunistic...
During the last three decades, strong progress was made in taxonomy of family Chydoridae (Crustacea: Cladocera), and results these revisions have become a valuable confirmation non-cosmopolitanism cladoceran distribution. But, to date, delineation between several chydorid genera (Pleuroxus Baird, 1843, Picripleuroxus Frey, 1993, Alonella Sars, 1862 Disparalona Fryer, 1968) has been intuitive rather than based on careful diagnostics. is genus with complicated confused taxonomy. We compiled...
The recent distribution of the Ponto-Caspian calanoid copepod, Eurytemora velox, in Western and Eastern Europe has been well-documented; however, there are no studies on genetic diversity recently discovered Siberian species population. To contribute towards filling this gap, were investigated for E. velox collected Urals Siberia Russian Federation to compare with European populations. In study, 44 specimens dissected morphological studies, 22 from different geographical points analyzed...
In previous papers, it was shown that the Far East is a territory where moving south, Boreal fauna fluently changed to Tropical fauna. Kotov (2016) proposed place all taxa from northern portion of in several faunistic complexes according area their differentiation past, i.e. Pleistocene refugia. But many daphniids and chydorids were placed an artificial group non-revised rather than certain complex. Ilyocryptids are less numerous better studied, they could be used as model test such...
РЕЗЮМЕ.Фауна микроскопических ракообразных (Cladocera, Copepoda и Ostracoda) континентальных водоемов юга Дальнего Востока Российской Федерации исследована несравнимо хуже, чем фауна европейской части РФ.Цель данной работы -провести инвентаризацию фауны Cladocera озера Болонь его бассейна оценить биогеографический статус найденных видов.В общей сложности нами было найдено 45 таксонов (среди них, определение четырех возможно только до уровня рода) 13 Copepoda.Для некоторых приведены...
Biotic introductions are an ongoing disruption for many ecosystems. For passively dispersed freshwater zooplankton, transcontinental have been common but poorly studied in the southern hemisphere. Here we assess hypothesis of recent introduction populations Chydorus sphaericus group (Crustacea: Cladocera) Australia. We analyzed 254 sequences (63 original sequences) from cytochrome oxidase I region mitochondrial DNA sp., which included global representation. Three Australian were connected...
Previous studies provided evidence of the mixing boreal–tropical cladocerans (Crustacea) in Far East Eurasia, as well presence numerous pre-Pleistocene relict endemics. In this study, we hypothesize that colonization history is reflected proportions endemic/boreal/tropical taxa among different habitat types within region. We analyzed 442 qualitative samples collected from seven sub-regions Russia and South Korea along a latitudinal transect approximately 2200 km, where identified 101...
A new species of genus Pseudochydorus Fryer, 1968 (Cladocera: Anomopoda: Chydoridae) is described from South-East Asia. P. bopingi sp. nov. differs Palearctic globosus (Baird, 1843) by a smaller size, well-developed flattened flange along the posterior margin valves, shorter rostrum, ocellus, and details antenna thoracic limb II morphology. known South China Vietnam, but probably has wider distribution. Our results suggest that populations outside may belong to separate as well.
Taxa of the genus Ceriodaphnia Dana, 1853 (Cladocera: Daphniidae) are ubiquitous in temperate and tropical lakes, taxonomy is confused. Moreover, present keys often regional insufficient for taxonomic assignment species at a global scale. This communication aimed improving our understanding C. dubia s.l. group. We redescribe from Northern Eurasia describe new Central Yakutia (Eastern Siberia, Russia). In contrast to typical members group, nikolaii sp.nov. has postabdomen parthenogenetic...
Most studies of water flea (Crustacea: Cladocera) invasions are concentrated on a few taxa with an obvious harmful influence native ecosystems, while our knowledge cases anthropogenic introduction not-so-obvious consequences, in most other taxa, is poor. We found the Volga basin (European Russia) population that contained D. curvirostris Eylmann, 1887 and its hybrids korovchinskyi Kotov et al. 2021. The latter taxon endemic to Far East it has appeared as result past human-mediated...
Bromeliads (Bromeliaceae) are an extremely diverse family of the angiosperms widely distributed in tropical and subtropical regions Americas West Africa. They often serve as phytotelmata, accumulating rainwater between leaves. Such water reservoirs can be inhabited by organisms. But to date not much attention is paid inventory these organisms, with careful identification each taxon. We found a microcrustacean Disparalona hamata (Birge, 1879) (Crustacea: Cladocera) bromeliad Tillandsia...
The Mediterranean area is a biodiversity and endemism hotspot. Circum-Mediterranean taxa are known among different hydrobionts, including the water fleas. Some endemic cladoceran have been described or redescribed according to modern taxonomical standards, but accurate drawings missing for others. Here we redescribe Daphnia chevreuxi Richard, 1896 (Crustacea: Cladocera) briefly review available data on its distribution ecology. species confirmed be typical inhabitant of temporary ponds...
