Study and conservation of marine biodiversity in Indonesian reefs Clara Serra,Marco Segre Reinach,Yurij Barrettara and Marco Baj Coral Eye,Indonesian reef research out post

submitted by: Marco_Segre

High level of biodiversity means plenty  variety of species, high resilience and many ecological, cultural and economic  advantages.
The Italian-Indonesian group Coral Eye, thanks to the past cooperation with Italian University “Politecnica delle Marche”, realized in 2010 the first campus “Mata Karang”. The aim of the campus is to provide on- site the perfect instrument for all scientists involved in the study and preservation of biodiversity in coral reef ecosystem.

Cetaceans, are they mammals or fish? Our point of view

submitted by: Carmen_Arija
One of the current goals of Conservation Biology is the education of human society so that people establish relationships with nature depending on their culture. In this paper we began to explore the knowledge about cetaceans that Spanish urban society has. To do this, 411 people of different sex, ages, professions, educational levels and cities in Spain, were surveyed considering basic characteristics of cetaceans like "being a mammal" or "breathing through lungs". Our results show that...

Predicting the likely distribution of the invasive Pacific oyster Crassostrea gigas in a Norwegian fjord

submitted by: Pia_Norling
The invasive Pacific oyster Crassostrea gigas has since 2007 established populations in Norwegian waters. The origin of C. gigas found in Norway is unknown, but several plausible factors such as unusually warm water temperatures and persistent westerly winds during 2006 may have caused an inflow of larvae from the Danish Wadden Sea. The species is known to drastically change blue mussel beds and soft bottom areas into massive oyster reefs with negative impact on birds and other marine...

Local extinction risk of Acropora at Koh Kood, Thailand

submitted by: Thamasak_Yeemin
There are many shallow coral reefs and coral communities on pinnacles around Koh Kood, Trat Province and its vicinity where are located near the borderline between Thailand and Cambodia, in the eastern part of the Gulf of Thailand. Coral reefs in the Gulf of Thailand suffered a severe and extensive mass bleaching phenomenon in the summer months of 2010 and most coral taxa were affected in different levels of severity. Bleaching levels were relatively high at the eastern Gulf of Thailand....

Long-term change in zooplankton functional diversity in the western subarctic North Pacific

submitted by: Sanae_Chiba

Spatio-temporal variation in zooplankton community structure in the western subarctic North Pacific based on the historically collected zooplankton samples for 1960s - 2000, the Odate Collection, was investigated in relation to decadal climatic and hydrographic variations. Species and size structure of copepods in the region varied well responding the decadal dynamics of the subarctic and subtropical oceanic currents, Oyashio and Kuroshio, respectively.

Predicting patterns of algal beta diversity on shallow, temperate reefs.

submitted by: Nicole_Hill

Beta diversity, the variation in species composition among sites within a region, is a key concept for conserving and managing biodiversity. However, beta-diversity is rarely studied across the large spatial scales relevant for management, particularly in the marine environment.

Variation of macrofaunal assemblage in a sandy beach of  Gulf of Cadiz (Spain) along a touristical pressure gradient

submitted by: Reyes-Martínez_Mª
   Globally, the coast is undergoing a process of degradation, due to increased population, increased demand for its resources and the uncontrolled urban development (Schlacher et al., 2008). This degradation is noticeable along of Andalusian coast where it has given priority to tourist development as the main engine of the economy of the community. Such use has a direct impact on invertebrates species inhabiting the beaches, and an indirect...

Assessing functional diversity of subtidal biocenosis on rocky shores. A methodological study from the bay of Saint Malo, France.

submitted by: Régis_Gallon
The Marine Strategy Framework directive enforces member states of Europe to achieve a good environmental status before 2020. For the first time in an European directive, an ecosystemic approach is explicitly stated. In this context, methodological approaches need to be implemented to develop indicators of biological diversity but also abundance and biomass. Subtidal rocky habitats have been little studied up to now, and the role of red algae habitats in terms of community structure,...

Annotating the Deep sea using imagery from NEPTUNE Canada Ocean Network

submitted by: Marjolaine_Matabos

The limited accessibility to the deep-sea results in a under estimation of biodiversity as rare species are not properly sampled, especially in abyssal plain characterized by low densities. Long-term and continuous observations of the seafloor using undersea cabled observatories will contribute to the sampling effort needed to better document marine biodiversity.

Threatened canopy algae: an experimental investigation of factors affecting the successful transplantation on artificial marine infrastructures.

submitted by: Filippo_Ferrario
We present the results of experimental work aimed at examining the feasibility of controlling the growth of desirable species on man-made coastal defense structures (CDS). We focused on important habitat forming macroalgae of the genus Cystoseira threatened by loss in the Mediterranean sea. We analyzed the role of grazing in influencing the survival and growth of Cystoseira on CDS, as pilot tests suggested herbivory has a potentially limiting role. Grazers impact on growth and survival of...
