The growing interest in mineral resources of the deep sea, such as seafloor massive sulphide deposits, has led to an increasing number exploration licences issued by International Seabed Authority. In Indian Ocean, four licence areas exist, resulting new hydrothermal vent fields and discovery species. Most studies focus on active venting including their ecology, but non-vent megafauna Central Ridge South East remains poorly known.In framework Ocean Exploration project German license area for...
During the KuramBio expedition in 2012, previously unknown Macrostylidae (Crustacea, Isopoda) were collected from Northwest Pacific Basin near Kuril–Kamchatka Trench. Three of these species are described herein, Macrostylis amaliae sp. nov., M. daniae nov. and sabinae using a combination morphological molecular–genetic approaches. The use confocal laser scanning microscopy was evaluated found to be valuable, non-destructive method visualize precious type material, as opposed electron...
Abstract How far are species distributed on the abyssal plains? Spanning from 3000 to 6000 m below sea level, plains cover three-quarters of ocean floor and largest but also least explored habitat Earth. The question vertical horizontal distribution is central understanding biogeographic population genetic processes within inhabiting deep-sea benthos. Amphipod crustaceans an important dominant taxon in this ecosystem. As they brooders, their dispersal capacities more limited compared with...
A white humpback whale (Megaptera novaeangliae) was observed on several occasions off Svalbard, Norway, during August 2012. The animal completely white, except for a few small dark patches the ventral side of its fluke. baleen plates were light-coloured, but animal’s eyes had normal (dark) colouration. This latter characteristic indicates that not an albino; it leucistic individual. full-sized adult and engaged in ‘‘bubble-feeding’’, together with 1520 other whales, each time seen....
Intact voucher specimens are essential to allow detailed morphological observations on that used in molecular genetic studies. This can be achieved either by dissection of small, taxonomically uninformative parts the body for DNA extraction or employing non-destructive methods. The latter is particularly important small-bodied animals. Here we test effects Chelex-based integrity setae and setules Amphipoda, fragile structures great taxonomic importance. Our results show using Chelex had no...
The abyss is a homogeneous and barrier-free sediment habitat. At least that what the text books say. Yet, at same time we know abyssal communities are locally highly diverse. It appears contradictory seafloor habitat free of barriers poor in heterogeneity can host rich biodiversity. Likewise evolutionary origins this diversity remain dark, although it has been proposed organisms encounter depth originated from much more heterogeneous bathyal zone. During interdisciplinary Vema-TRANSIT...
