Article
Full-text available
Until recently many oceanic zooplankton species have been considered as cosmopolitan organisms. At present it became evident that some of them comprise many distinct molecular operational taxonomic units (MOTUs) that often are regarded as cryptic species. As they can significantly change our perceptions of large-scale biogeographic patterns, it is...

Evolutionary mechanisms driving the diversification of pelagic animals remain poorly understood, partly due to the high levels of gene flow in the open ocean. We use molecular phylogenetics, morphological, and phylogeographic approaches to test the allopatric speciation model in respect to the Atlantic krill genus Nematoscelis. Based on our observa...

The first comprehensive phylogenetic study of Euphausiacea (all 86 valid species) is presented. It is based on four molecular markers and 168 morphological characters (including 58 characters of the petasma). Phylogenetic analyses support the monophyly and robustness of the families Bentheuphausidae and Euphausiidae and reveal three major clades fo...

Diel and seasonal vertical migrations of zooplankton represent a widespread phenomenon occurring in marine and freshwater environments. Diel migrations are panoceanic, while seasonal migrations usually occur in temperate and polar areas. This paper describes differences in the diel and seasonal vertical migrations in the Drake Passage north and sou...

The first comprehensive phylogenetic study of the family Oplophoridae is based on four molecular markers and 87 morphological characters. We have examined and coded five major groups of morphological characters related to the rostrum (nine characters), the carapace (10), the abdomen and telson (34), the exopods (eight) and the armature of the poste...

The deep sea is the largest biome on Earth and hosts the majority of as yet undescribed species; description of these may trigger a new mindset about evolution and function of characters. We describe and diagnose a new genus and species Sclerodora crosnieri sp. nov. belonging to the superfamily Oplophoroidea. We examined and coded 81 characters for...
Article
Benthesicymidae is a monophyletic group of Decapoda adapted to a life on the sea-floor, in the near-bottom layer, in the bathy- and in the mesopelagic, within an impressive depth range from a few hundred metres (Gennadas) to several thousand metres (Benthesicymus). Higher taxa are known to conquer all main oceanic biotopes such as the benthic, bent...
Article
The shrimp genera Ephyrina, Meningodora and Notostomus have an unusual carapace strengthened with carinae and a half-serrated mandible, which may suggest a possible monophyly of this group. Here we test this hypothesis and present the first phylogenetic study of these genera based on 95 morphological characters (all valid species coded) and six mol...
Article
A phylogenetic study of deep-sea dendrobranchiate genera Altelatipes, Benthesicymus and Benthonectes based on four molecular markers and 91 morphological characters is presented. All currently recognized species of these genera, representatives of all other genera and species groups of Benthesicymidae, and three outgroups were included in the analy...
Article
The phylogenetic study of the deep-sea genus Bentheogennema is based on four molecular markers and 79 morphological characters. All four previously recognized species and two new species of Bentheogennema, representatives of all other genera and species groups of Benthesicymidae, and three outgroups were included in the analyses. We have examined a...

The Southern Ocean is a crucial component of the global climate system and plankton communities inhabiting the Ocean are important in the global carbon cycle. Our paper is aimed to reveal possible factors, which keep identity and explain changes of the community structure at the mesoscale. We tested the absolute values of environmental variables (e...
Article
Full-text available
The paper addresses the phylogeny and classification of the hydrothermal vent shrimp family Alvinocarididae. Two morphological cladistic analyses were carried out, which use all 31 recognized species of Alvinocarididae as terminal taxa. As outgroups, two species were included, both representing major caridean clades: Acanthephyra purpurea (Acanthep...
Article
Full-text available
Some holoplanktonic species are cosmopolitan and have continuous distribution in the world’s oceans. For most of these species it is not clear whether there is unhampered gene flow between far distant populations or they represent a complex of cryptic species. In the present study we investigated genetic diversity of the cosmopolitan chaetognath Eu...
Article
Full-text available
The Southern Ocean is characterized by the complex system of oceanic fronts that maintain the latitudinal zonality of biotopes. These fronts are boundaries of water masses with different hydrophysical characteristics. We explore the genetic differentiation of the dominant zooplankton species in regards to the complex hydrophysical zonality of the S...

The variability of the mesozooplankton stock in the shelf pelagic communities was studied in the late summer and autumn of 2006–2008. The plankton community’s structure and distribution were described for the shoreward transect (Gelendzhik city vicinity). The indirect and direct effect of the ctenophores Mnemiopsis leidyi and Beroe ovata on the mes...

The mesoscale distribution of two chaetognath species, Eukrohnia hamata and Sagitta gazellae, found in the Drake Passage in October and November of 2008 was studied using a stationary grid in the area of the Antarctic Polar Front. The distance between the stations was around ten miles. The most abundant chaetognath species was Eukrohnia hamata, whi...
