The influence of environmental complexity on brain development has been demonstrated in a number of taxa, but the potential influence of social environment on neural architecture remains largely unexplored. We investigated experimentally the influence of social environment on the development of different brain parts in geographically and genetically isolated and ecologically divergent populatio...

The prevalence of indole-positive organisms in the gut and environment of marine animals was studied. Indole formation by a group of the isolates was found to occur only in the presence of tryptophan. The isolates examined were all assigned to the genus Vibrio.

This work reports on the experience gained in the context of the development of a system of wireless sensor networks for marine environment monitoring, as a part of the GeoGrid project. The proposed system employs a monitoring network composed of commonly available motes, equipped with sensors for monitoring water quality in restricted marine environments. Those lowerend nodes communicate among...

We discuss the voltammetric methods that are used to assess metal-organic complexation in seawater. These consist of titration methods using anodic stripping voltammetry (ASV) and cathodic stripping voltammetry competitive ligand experiments (CSV-CLE). These approaches and a kinetic approach using CSV-CLE give similar information on the amount of excess ligand to metal in a sample and the condi...

The Arctic is a region in the northernmost hemisphere of the Earth. It is known for its extreme environmental conditions, in particular its cold temperatures, high winds, snow, and ice. Yet, life in this polar region is plentiful and includes both terrestrial and marine organisms. The Arctic Ocean provides for a unique, cold-temperatureadapted ecosystem containing plankton, marine mammals, and ...

Although natural light sources produce depolarized light, partially linearly polarized light is naturally abundant in the scenes animals view, being produced by scattering in air or water or by reflection from shiny surfaces. Many species of animals are sensitive to light's polarization, and use this sensitivity to orient themselves using polarization patterns in the atmosphere or underwater. A...

The long-term goals are to develop novel techniques to measure and predict, through modeling, the effect of sound on the marine environment. Modeling includes acoustic sources, propagation and the interaction of sound with animal behavior models. Determining the necessary environmental information such as bathymetry, sound speed and seabed properties for accurate modeling is also an essential c...

The past decade has witnessed the proliferation of mature modeling packages as well as rapidly evolving computer technology which is making high-resolution modeling possible. In addition, the Internet phenomenon with constantly increasing network speed has driven technology revolutions, one of which is the development of web portals with easy user interfaces that hides the complexities of the u...
