Foraminifera from Peru: Brizalina alata
Foraminifera are protozoans found in all marine environments, they secrete a test of calcium carbonate. These organisms usually dominate both shallow and deep sediments.Despite a strong presence in all the oceans of the world, still remains largely unknown its diversity, and still do not know all benthic processes in which they participate.

Peru has one of the most productive seas in terms of fish production, but other components of this large marine ecosystem are also very important in relation to its functioning. Benthic organisms have a key role in several processes related with organic matter cycling and others aspects of metabolisms of the marine system. Central Perú was sampled in 2007 during Galathea Expedition*. Here, I present a preliminary taxonomic identification** of some forams found in Huacho-Peru, corresponding to 100-300 m depth range.

Postdoctoral Researcher position - Sars International Centre, Bergen Norway
Postdoctoral Researcher
Correlative light and electron microscopy and neural circuit reconstruction
The Sars International Centre for Marine Molecular Biology is now
offering a two-year postdoc position in a research group working on cell
type and organ system evolution in invertebrates. The announced
position focuses on the application of correlative and 3D electron
microscopic techniques for integration of light microscopic gene
expression and ultrastructural datasets. The project forms an integral
part of collaborative efforts to uncover neural circuitry of
evolutionary conserved cell types in the central nervous system of the
emerging invertebrate model organism Platynereis dumerilii for analysis of animal nervous system evolution.Extensive resources for Platynereis dumerilii are now established by several labs (gene knock down, transgenesis, advanced imaging tools) and genome sequencing is in process making this protostome representative a valuable model for molecular and evolutionary research.
The position involves a broad spectrum of electron microscopic methods from automated TEM and SEM imaging of serial sections, 3D image processing, axon tracing, immunogold studies and new developments in correlative light and electron microscopy for studying gene expression on the cellular level. The successful applicant will have a solid background in electron microscopy and interest in function and evolution of invertebrate nervous systems. Prior experiences in advanced 3D image processing and molecular biological techniques are advantageous.
The position is available immediately; the start date is negotiable
The salary for Postdoctoral Researcher (code 8151) starts at NOK 460 593 and will be adjusted accordingly following 2012 wage settlements.
The Sars International Centre is a partner of the European Molecular Biology Laboratory (EMBL) and a department of Uni Research AS, affiliated with the University of Bergen. The Centre is focused on basic research in marine molecular biology, developmental biology and evolution, through genetic and comparative studies of invertebrates and vertebrates. The Centre offers excellent molecular and imaging resources and the University EM facility has currently been upgraded with new SEM and TEM equipment for automated image acquisition. EMBL resources will be directly available for the project due to close collaboration with EMBL members.
Uni Research has employee insurance and pension agreements and is an equal opportunity employer.
For further information regarding the position and scientific content of the project please contact Dr. Harald Hausen, Group Leader: harald.hausen@sars.uib.no.
Written applications in English, including CV, summary of educational and work experience, a brief statement of research interest and contact information for two references can be sent to: Uni Sars Centre, HR Officer, Bergen High Technology Centre, Thormøhlensgt. 55, N-5008 Bergen, Norway. Please mark applications 12 Sars 04. Application deadline is 22 June 2012.
Please note that applications sent by e-mail will not be considered.

Benthic Ecology Meeting 2012, USA
The Benthic Ecology Meeting (BEM) is one of the largest scientific meetings for marine biologists in the USA. The 41st meeting will be hosted by Old Dominion University (ODU) and held in the Norfolk Waterside Marriott Hotel. At the 2012 BEM we anticipate more than 700 registrants; a mix of the nation's top marine ecologists and up-and-coming graduate and undergraduate students...

Touring around ocean bottom
The seabed is the largest of the biomes and the least known on the planet. Here is an excellent approach to its most popular features and areas mapped.
