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.

Benthic Ecology Meeting 2012, USA

The Benthic Ecology Meeting (BEM) is one of the largest scientific meetings for marine biologists in the USA. The 41^st 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...

The Dead Zone (a short clip about this topic)

Bleaching of corals and sea surface temperatures

One of the biggest problems affecting the oceans is the acidification and its consequences on as the ecological conditions as the marine life diversity. A notorious example is the impact generated on coral reefs. Here a short-video that illustrates this important point.

 

In parallel, the increase in sea surface temperature in recent years has also been important.
