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.

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

   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.

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.

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...
