  journal={Marine Biology},
The genus Nyctiphanes (Malacostraca, Euphausiacea) comprises four neritic species that display antitropical geographic distribution in the Pacific (N. simplex and N. australis) and Atlantic (N. couchii and N. capensis) Oceans. We studied the origin of this distribution applying methods for phylogenetic reconstruction and molecular dating of nodes using a Bayesian MCMC analysis and the DNA sequence information contained in mtDNA 16S rDNA and cytochrome oxidase (COI). We tested hypotheses of… 

An introduction to the biology of Northern krill (Meganyctiphanes norvegica Sars).

Molecular phylogeny of South African abalone, its origin and evolution as revealed by two genes

All five South African species were revealed as a monophyletic group with a sister relationship to the Australian endemics clade and a split within the South African group was revealed as well as further speciation within one of the two subclades.

Review of the biology of the krill genus Nyctiphanes G.O. Sars, 1883 (Euphausiacea: Euphausiidae): challenges for future research on environmental change

This work reviews current knowledge of the biogeography, reproductive biology, physiology, biochemistry, ecology, and parasitology of the four species of Nyctiphanes and suggests new multi-focal studies on the effects that environmental variables have on reproductive aspects, survival, growth, and physiology are especially critical to address under future environmental change.

A review of marine phylogeography in southern Africa

This review describes the state of marine phylogeography in southern Africa, that is, the study of evolutionary relationships at the species level, or amongst closely related species, in relation to the region’s marine environment, and focuses particularly on coastal phylegeography.

To date, 53 helminth species have been discovered in the gastrointestinal tracts and other internal organs of Barents Sea birds. These parasites circulate in pelagic and coastal biocenoses. This

The first description of Antarctic krill (Euphausia superba) dates back to 1850. After a period of taxonomic work and the description of several synonyms, detailed studies on the morphology, internal

A phylogenetic study of krill (Crustacea: Euphausiacea) reveals new taxa and co‐evolution of morphological characters

The first comprehensive phylogenetic study of Euphausiacea is presented and reveals three groups of morphological characters, which are probably coupled with the same biological role and thus interlinked evolutionarily: antennular peduncle and petasma, eyes and anterior thoracopods, and shape of carapace and pleon.

Euphausiacea diversity in a trans-oceanic transect through the South Atlantic Ocean: the first Atlantic record of Thysanopoda astylata Brinton, 1975.

This report constitutes the first record of Thysanopoda astylata Brinton, 1975 in Atlantic waters, and investigates species composition and distribution of euphausiids along a longitudinal transect in this region, with an emphasis on ThysAnopoda.

No state change in pelagic fish production and biodiversity during the Eocene–Oligocene transition

The Eocene/Oligocene (E/O) boundary (~33.9 million years ago) has been described as a state change in the Earth system marked by the permanent glaciation of Antarctica and a proposed increase in

Population genetic structure and demographical history of South African abalone, Haliotis midae, in a conservation context

This study reported the first microsatellite and Single Nucleotide Polymorphism (SNP) markers developed specifically for Haliotis midae, which gave evidence for subtle differentiation between West and East coast populations that correlates with a hydrogeographic barrier in the vicinity of Cape Agulhas.



Origin of the antitropical distribution pattern in marine mussels (Mytilus spp.): routes and timing of transequatorial migration

Data indicate that southern hemisphere mussels arose from a migration event from the northern hemisphere during the Pleistocene via an Atlantic route, suggesting a second, more recent migration to the southern hemisphere.

A molecular phylogeny of the patellid limpets (Gastropoda: Patellidae) and its implications for the origins of their antitropical distribution.

It is suggested that Patella s.s. may have originated at least as early as the Upper Cretaceous and that its northern distribution may have been achieved at the same time, and some evidence that the patellids may not be monophyletic is presented.

Pliocene closing of the Isthmus of Panama, based on biostratigraphic evidence from nearby Pacific Ocean and Caribbean Sea cores

Pliocene and Pleistocene planktonic foraminiferal biogeography and paleoceanography have been examined in Deep Sea Drilling Project (DSDP) sites of the Panama Basin (Pacific Ocean) and Colombian and

Signatures of seaway closures and founder dispersal in the phylogeny of a circumglobally distributed seahorse lineage

The evolution of the circumglobally distributed seahorse lineage was strongly influenced by founder dispersal, and it is suggested that this mode of speciation may be particularly important in marine organisms that lack a pelagic dispersal phase and instead disperse by means of rafting.

Molecular phylogeny of Eastern Pacific porcelain crabs, genera Petrolisthes and Pachycheles, based on the mtDNA 16S rDNA sequence: phylogeographic and systematic implications.

The authors' phylogenetic trees indicate that the genus Petrolisthes is divided into two main clades, reflecting morphological features, and suggests an antitropical distribution; north and south temperate species form one clade and tropical species form a second clade.

Shallow population histories in deep evolutionary lineages of marine fishes: insights from sardines and anchovies and lessons for conservation

It is demonstrated that regional populations of sardines and anchovies are subject to periodic extinctions and recolonizations, and management strategies should incorporate the idea that even extremely abundant populations may be relatively fragile on ecological and evolutionary time scales.

Larval development of Euphausia superba Dana, 1852 and a phylogenetic analysis of the Euphausiacea

From this analysis the taxon names 'Euphausiina', 'Nematoscelini', and 'Nemisatoscelina' are introduced for in-groups of the tax on the Euphalusiacea as representing monophyletic units.
