A census of marine life: Unknowable or just unknown? ArchiMer
Decker, Cj; O'Dor, R.
As an introduction to the entire volume, this article outlines the relationships among the five elements of the Census of Marine Life (CoML) that create new knowledge: (1) The Ocean Biogeographic Information System (OBIS), a marine component of the Global Biodiversity Information Facility, links marine databases around the world to provide an Internet accessible, dynamic interface for comparing species-level, geo-referenced biodiversity data in relation to ocean habitats. The entire CoML field project data will be managed in and accessible through OBIS. (2) The History of Marine Animal Populations (HMAP) is a unique new synthesis of historical and biological research that will document marine biodiversity, globally, up to 500 years ago, before significant...

A Miocene perspective on the evolution of the Amazonian biota Naturalis
Wesselingh, F.P.; Salo, J.A..
Between c. 23 and 8 Ma, western Amazonia was occupied by the vast Pebas long-lived lake/wetland system. The Pebas system had a variety of influences over the evolution of Miocene and modern Amazonian biota; it formed a barrier for the exchange of terrestrial biota, a pathway for the transition of marine biota into freshwater Amazonian environments, and formed the stage of remarkable radiations of endemic molluscs and ostracods. The lithological variation of the Pebas Formation has furthermore enhanced edaphic heterogeneity in western Amazonia, sustaining present-day high terrestrial diversity in the region.

A new cryptic species of lizard (Sauria: Teiidae: Gymnophthalmus) from Venezuela Naturalis
Hoogmoed, M.S.; Cole, C.J.; Ayarzaguena, J..
Gymnophthalmus cryptus spec. nov. is described and illustrated on the basis of males and females collected in the Territorio Federal Amazonas, southern Venezuela. Some details on ecology and distribution are also presented. The females of G. cryptus are very similar to the unisexual Gymnophthalmus underwoodi, which also occurs in the Guianan Region. In fact, G. cryptus is one of the best candidates for future genetic research to determine whether it is the missing ancestor of G. underwoodi, a parthenogenetic species of hybrid origin (G. speciosus x G. spec.?). Two other series of previously unreported species of Gymnophthalmus from Venezuela are also discussed.

A new genus and species of characid fish from the Amazon basin: the recognition of a relictual lineage of characid fishes (Ostariophysi: Cheirodontinae: Cheirodontini) Neotropical Ichthyology
Bührnheim,Cristina M.; Carvalho,Tiago P.; Malabarba,Luiz R.; Weitzman,Stanley H..
Amazonspinther dalmata, a new miniature characid from the streams of rio Purus and rio Madeira, right bank tributaries of the rio Amazonas, is described as a new genus and species of the subfamily Cheirodontinae. The unique characters of the new genus and species are the three remarkable black blotches on the base of the dorsal, anal, and caudal fins, the anteriormost proximal radial of the anal fin with an anteriorly extended lamina entering the abdominal cavity, and the extremely elongate caudal peduncle. The reduced number of ventral procurrent caudal-fin rays (7-9), and the hemal spines of only posterior one, two, or sometimes three caudal vertebrae directly articulating with the ventral procurrent caudal-fin rays further diagnoses the new taxon from...

A perspective on the census of marine life. The role of natural history institutions for this programme ArchiMer
Pierrot-bults, Ac.
The Census of marine life programme (CoML) is expected to generate a large amount of information on the diversity, distribution, and abundance of marine communities, many of them new or poorly known. Institutions such as natural history museums can play a crucial role in providing the necessary tools to allow the CoML to advance knowledge in the fields of marine systematics and biogeography. These institutions can contribute taxonomic expertise to provide quality-controlled identifications of species; specimen collections to allow for cross-checking of occurrences and a historical context for new data; information, both paper and electronic, on taxonomy, ecology and other topics to enable researchers to review past work; education opportunities to inform...

A portal for the ocean biogeographic information system ArchiMer
Zhang, Yq; Grassle, Jf.
Since its inception in 1999 the Ocean Biogeographic Information System (OBIS) has developed into an international science program as well as a globally distributed network of biogeographic databases. An OBIS portal at Rutgers University provides the links and functional interoperability among member database systems. Protocols and standards have been established to support effective communication between the portal and these functional units. The portal provides distributed data searching, a taxonomy name service, a GIS with access to relevant environmental data, biological modeling, and education modules for mariners, students, environmental managers, and scientists. The portal will integrate Census of Marine Life field projects, national data archives,...

A taxonomic, phylogenetic and biogeographic study of the genus Acanthophora (Rhodomelaceae, Rhodophyta) Naturalis
Jong, Yde S.D.M. de; Hitipeuw, Creusa; Prud’homme van Reine, Willem F..
A cladistic analysis, based on a taxonomic revision is carried out for 7 Acanthophora species using 19 characters. Hypotheses on species affinities are based primarily on morphological characters. Because most species show only few distinctive characters, emphasis was placed on features of spine development, either in relation to vegetative or to reproductive structures. Global distribution of 7 Acanthophora species: viz. A. aokii, A. dendroides, A. muscoides, A. nayadiformis, A. pacifica, A. ramulosa, and A. spicifera, shows a discontinuous pattern. Although widely distributed species are present (A. muscoides and A. spicifera), a disjunct distribution of other species occurs in the Pacific (A. aokii), Indian Ocean (A. dendroides), East-Atlantic region...

A taxonomic survey of seaweeds from Eritrea Naturalis
Ateweberhan, M.; Prud’homme van Reine, W.F..
A survey of seaweeds was made in Eritrea in December 1995 and January 1996 on some islands of the Dahlak Archipelago and the surroundings of the port town of Massawa. During our study 101 specific and infraspecific taxa were identified, including 26 Chlorophyta, 20 Phaeophyta and 55 Rhodophyta. The survey resulted in 36 new records for Eritrea (11 Chlorophyta, 7 Phaeophyta and 18 Rhodophyta). Of these Eritrean records, 26 are new for the Red Sea (5 Chlorophyta, 4 Phaeophyta and 17 Rhodophyta). Comparison of records of seaweeds from localities in Eritrea to those from other localities in Eritrea as well as from other coasts of the western Indian Ocean have revealed that the regional distribution of seaweeds in the Red Sea is very patchy and that generally...

Actualisation des donnees sur l'ecologie, la biogeographie et la phylogenie des Ampeliscidae (crustaces-amphipodes) Atlantiques apres la revision des collections d'E. Chevreux ArchiMer
Bellan-santini, D; Dauvin, J.
In the world, the Ampelisca genus is constituted by more than 140 species, which are found between 0 to 4000 m depth. Phylogeny, biology and ecology are the most important interest in this genus. The present analysis of new and older collections (E. Chevreux) have permitted to describe 11 new species. 41 species are listed in the north-eastern Atlantic fauna. These are different arguments to think that Ampelisca groups was actually in speciation. Two groups issued from a phenetic analysis are discriminated by their apomorphic levels. More than of the third are endemic species. 21 species are present only in one of the five biogeographic region. 23 species are limited to the continental shelf, 34 live up to the first 1000 meters and 4 are bathyal. 2 species...

Adding new pieces to the Azadinium (Dinophyceae) diversity and biogeography puzzle: Non-toxigenic Azadinium zhuanum sp. nov. from China, toxigenic A. poporum from the Mediterranean, and a non-toxigenic A. dalianense from the French Atlantic ArchiMer
Luo, Zhaohe; Krock, Bernd; Mertens, Kenneth; Nezan, Elisabeth; Chomerat, Nicolas; Bilien, Gwenael; Tillmann, Urban; Gu, Haifeng.
The marine planktonic dinophyceaen genus Azadinium is a primary source of azaspiracids, but due to their small size its diversity may be underestimated and information on its biogeography is still limited. A new Azadinium species, A. zhuanum was obtained from the East China Sea and Yellow Sea of China by incubating surface sediments. Five strains were established by isolating single germinated cells and their morphology was examined with light microscopy and scanning electron microscopy. Azadinium zhuanum was characterized by a plate pattern of Po, cp, X, 4′, 2a, 6′′, 6C, 5S, 6′′′, 2′′′′, by a distinct ventral pore at the junction of Po, the first and fourth apical plates, and a conspicuous antapical spine. Moreover, Azadinium poporum was obtained for the...

Amphi-Atlantic distribution of the subterranean amphipod family Metacrangonyctidae (Crustacea, Gammaridea) Naturalis
Jaume, Damià; Christenson, Keith.
Members of the strictly stygobiont, continental subterranean amphipod family Metacrangonyctidae are reported for the first time outside the Old World. Two new species of Metacrangonyx are described from two widely separated localities in the Dominican Republic (Hispaniola), one facing the Caribbean and the other the Atlantic ocean. The discovery of metacrangonyctids in the western Atlantic suggests that they are an ancient subterranean lineage tied to the shores of the Tethys belt, and thus weakens previous biogeographic arguments raised to favour their separate and independent family status with respect to the Hadziidae. The discovery in the Mediterranean of marine populations of metacrangonyctids is reported as well, and both findings are used to test...

An unusual sea anemone from slope depths of the tropical west Pacific: range extension and redescription of Isactinernus quadrilobatus Carlgren, 1918 (Cnidaria: Actiniaria: Actinernidae) Naturalis
Fautin, D.G.; Hartog, J.C. den.
The sea anemone species Isactinernus quadrilobatus Carlgren, 1918, and Synactinernus flavus Carlgren, 1918, which were described in new monotypic genera from few specimens collected in southern Japan, are synonymized, based on many more specimens from the South Pacific. As well as the geographic range, the depth range of this species has been extended to 110-700 m. The species had been distinguished primarily on whether the oral disc had four lobes (I. quadrilobatus) or eight (Synactinernus flavus) – we conclude their number is largely related to size of the animal. Other features that Carlgren had used to differentiate the genera (and species) are inconsistently present and do not correlate with lobe number.

An updated checklist of the marine fish fauna of Reunion Island, South-Western Indian Ocean ArchiMer
Letourneur, Yves; Chabanet, Pascale; Durville, Patrick; Taquet, Marc; Teissier, Emmanuel; Parmentier, Maurice; Quero, Jean-claude; Pothin, Karine.
The ichthyofauna of Reunion Island, Southwestern Indian Ocean, was sampled during several ecological and artisanal fisheries studies. Information from these investigations and from other sources were included to compile the present checklist of the marine fishes of the island. A total of 885 species belonging to 150 families was recorded. Nine species are known only from Reunion, indicating endemism of about 1.0%. The most speciose families (Labridae, Gobiidae, Serranidae, and Pomacentridae) were also among the most speciose at the neighbouring Mauritius Island (except gobiids), and, generally, on other islands in the Indian Ocean area (Maldives, Chagos, Madagascar and Christmas Island). The Gobiidae only represented 5.4% of the ichthyofauna, which was...

Analyse des déterminants environnementaux de la variabilité du recrutement - approche macroécologique appliquée aux populations exploitées du Nord-Est Atlantique ArchiMer
Brunel, Thomas.
Recruitment - the number of young fishes that integrate each year the exploitable stock¿ has a central importance for stock dynamics. The high temporal variability in recruitment is a result of the environmental influence on survival during early life stages. Understanding the determinism of the influence of environment on recruitment remains one of the most important question in fisheries ecology. The present work aimed at answering some general questions about the influence of environment on fish recruitment using a macroecological approach. The study focused on the exploited fish populations of the Northeastern Atlantic. The first chapter of the thesis makes a review of the different methods used to estimate recruitment, compares recruitment estimates...

Areas of endemism in the southern central Andes Darwiniana
Aagesen,Lone; Bena,Maria J.; Nomdedeu,Soledad; Panizza,Adela; López,Ramiro P.; Zuloaga,Fernando O..
This paper analyzes the distribution of vascular plants species endemic to the southern central Andes (south-western Bolivia and north-western Argentina). All 540 species endemic to the study regions (approx. 720600 km²) have been included in the analysis. The main part of the endemic species is found in semiarid habitats between 1500-3500 m asl pointing to the topographically complex plateau, slope, and valley system of the southern central Andes as the main locations for its endemic flora. The distribution of the endemic species within arid sites is in contrast with that of vascular plant diversity in general, as the most diverse habitat of the region is the moist subtropical Tucumano-Bolivian Yungas forest of the eastern Andes slope. A total of 17 well...
