High diversity and pan-oceanic distribution of deep-sea polychaetes: Prionospio and Aurospio (Annelida: Spionidae) in the Atlantic and Pacific Ocean
Provedor de dados: 5
Autores: Guggolz, Theresa; Meißner, Karin; Schwentner, Martin; Dahlgren, Thomas G.; Wiklund, Helena; Bonifácio, Paulo; Brandt, Angelika.
Prionospio Malmgren 1867 and Aurospio Maciolek 1981 (Annelida: Spionidae) are polychaete genera commonly found in the deep sea. Both genera belong to the Prionospio complex, whose members are known to have limited distinguishing characters. Morphological identification of specimens from the deep sea is challenging, as fragmentation and other damages are common during sampling. These issues impede investigations into the distribution patterns of these genera in the deep sea. In this study, we employ two molecular markers (16S rRNA and 18S) to study the diversity and the distribution patterns of Prionospio and Aurospio from the tropical North Atlantic, the Puerto Rico Trench and the central Pacific. Based on different molecular analyses (Automated Barcode...

Possible effects of global environmental changes on Antarctic benthos: a synthesis across five major taxa
Provedor de dados: 5
Autores: Ingels, Jeroen; Vanreusel, Ann; Brandt, Angelika; Catarino, Ana I.; David, Bruno; De Ridder, Chantal; Dubois, Philippe; Gooday, Andrew J.; Martin, Patrick; Pasotti, Francesca; Robert, Henri.
Because of the unique conditions that exist around the Antarctic continent, Southern Ocean (SO) ecosystems are very susceptible to the growing impact of global climate change and other anthropogenic influences. Consequently, there is an urgent need to understand how SO marine life will cope with expected future changes in the environment. Studies of Antarctic organisms have shown that individual species and higher taxa display different degrees of sensitivity to environmental shifts, making it difficult to predict overall community or ecosystem responses. This emphasizes the need for an improved understanding of the Antarctic benthic ecosystem response to global climate change using a multitaxon approach with consideration of different levels of biological...

CeDAMar global database of abyssal biological sampling
Provedor de dados: 5
Autores: Stuart, Carol T.; Arbizu, Pedro Martinez; Smith, Craig R.; Molodtsova, Tina; Brandt, Angelika; Etter, Ron J.; Escobar-briones, Elva; Fabri, Marie-claire; Rex, Michael A.
The Census of the Diversity of Abyssal Marine Life (CeDAMar), a division of the Census of Marine Life, has compiled the first comprehensive global database of biological samples taken in the abyssal plains of the world ocean. It is an essential resource for planning future exploration of the abyss, for synthesizing patterns of biogeography and biodiversity, and for environmentally safe exploitation of natural resources. The database is described in this article, and made available to investigators through the CeDAMar website.

Cutting the Umbilical: New Technological Perspectives in Benthic Deep-Sea Research
Provedor de dados: 5
Autores: Brandt, Angelika; Gutt, Julian; Hildebrandt, Marc; Pawlowski, Jan; Schwendner, Jakob; Soltwedel, Thomas; Thomsen, Laurenz.
Many countries are very active in marine research and operate their own research fleets. In this decade, a number of research vessels have been renewed and equipped with the most modern navigation systems and tools. However, much of the research gear used for biological sampling, especially in the deep-sea, is outdated and dependent on wired operations. The deployment of gear can be very time consuming and, thus, expensive. The present paper reviews wire-dependent, as well as autonomous research gear for biological sampling at the deep seafloor. We describe the requirements that new gear could fulfil, including the improvement of spatial and temporal sampling resolution, increased autonomy, more efficient sample conservation methodologies for morphological...

Redescription of Echinomunna horrida Vanhöffen, 1914, a highly derived and rare species from the Antarctic (Crustacea, Isopoda, Munnidae)
Provedor de dados: 16
Autores: Brandt, Angelika.
During an expedition with RV Polarstern (1998) a male specimen of Echinomunna horrida was collected in the supranet of an epibenthic sledge in the Weddell Sea, Antarctica. Due to an incomplete and poor description by Vanhöffen (1914) a redescription is necessary on the basis of the male from the Weddell Sea and the female syntypes from the East Antarctic.

Short notes and reviews A Storthyngura (Crustacea, Isopoda) from the Bellingshausen Sea, Antarctica
Provedor de dados: 16
Autores: Brandt, Angelika.
During the expedition ANT XI/3 with RV Polarstern 17 multiple corers were taken in the Bellingshausen Sea. From this material only a single, immature isopod was sorted. This specimen is a manca II of a presumably new species of the genus Storthyngura. However, as it is immature and only a single specimen was sampled, more material of this species will have to be collected prior to the description of a new species.

Cylindrarcturus longitelson n. sp. from the South Shetland Islands, Antarctica (Isopoda, Antarcturidae)
Provedor de dados: 16
Autores: Brandt, Angelika.
Cylindrarcturus longitelson n. sp., from north of King George Island, South Shetland Islands, is the second species of Cylindrarcturus, which is rediagnosed. The new species can be distinguished from C. elongatus Schultz, 1981 by its longer pleotelsonic spine, the smooth, unsculptured head and pereonites, and differences in antennula and maxilliped.

Frontoserolis abyssalis n. sp. and Serolis arntzi n. sp. (Serolidae, Isopoda) from the Antarctic deep sea
Provedor de dados: 16
Autores: Brandt, Angelika.
A new collection of Serolidae (Crustacea, Malacostraca) from the deep sea of the West-Atlantic part of Antarctica has been studied. Descriptions of the new species Frontoserolis abyssalis n. sp. and Serolis arntzi n. sp. are presented. F. abyssalis n. sp. is very similar to F. acuminata (Sheppard, 1957) and F. aestimabilis (Brandt, 1988), but can easily be distinguished from these by its vestigial eyes and a different ornamentation of head and pleotelson. S. arntzi n. sp. is most similar to S. rugosa, but can be discriminated from this species by the sculpture of the head, the pereonites and the pleotelson.

Acanthaspidia namibia n. sp. (Isopoda, Acanthaspidiidae) from the deep Angola Basin
Provedor de dados: 16
Autores: Brandt, Angelika.
Acanthaspidia namibia n. sp. was sampled off Namibia on the abyssal plain of the Angola Basin in 5390 m depth from board of the RV ‘Meteor’ in August 2000. Acanthaspidia neonotus (Menzies &amp; George, 1972) is the most similar species, which has also been described from the deep sea, but from the Pacific Ocean in a comparative depth. The new species differs in bearing numerous long simple setae all over the body surface, and in the length of the maxillipedal epipod, which reaches the third palpal article, whereas that of A. neonotus reaches only the first.

Storthyngura spinosissima n. sp. (Munnopsididae, Isopoda, Crustacea) from the Weddell Sea and the Drake Passage
Provedor de dados: 16
Autores: Brandt, Angelika.
Storthyngura spinosissima n. sp. is described from material obtained from the Weddell Sea, south of Vestkapp and in the Drake Passage, at a depth of 417-1681 m. The new species is most similar to S. praegrandis George &amp; Menzies, 1968, but differs in the following details: the dorsum of S. spinosissima n. sp. is covered by numerous small spine-like tubercles and short, hairlike setules, which are absent in S. praegrandis; the tubercles of the latter are less numerous; the interantennular space of S. spinosissima n. sp. is narrower than in S. praegrandis; the antennula of S. spinosissima n. sp. bears a less pronounced distomedial spine on the first peduncular article; and the uropodal endopods are slightly shorter and the exopods less wide in S....
