The East/Japan Sea (hereafter, the East Sea) is highly dynamic in its physical phenomena and biological characteristics, but it has changed substantially over the last several decades. In this study, a recent decadal trend of primary productivity in the East Sea was analyzed based on Moderate-Resolution Imaging Spectroradiometer (MODIS)-derived monthly values to detect any long-term change. The...

Plastic debris at the micro-, and potentially also the nano-scale, are widespread in the environment. Microplastics have accumulated in oceans and sediments worldwide in recent years, with maximum concentrations reaching 100 000 particles m(3). Due to their small size, microplastics may be ingested by low trophic fauna, with uncertain consequences for the health of the organism. This review foc...
Socioeconomic aspects of the Humboldt Current Large Marine Ecosystem – Extended Summary – Consultancy developed for the TDA-SAP process of the GEF-UNDP project: Towards ecosystem based management of the Humboldt Current Large Marine Ecosystem. Lima, Peru. 21p.
CURRENT SCIENCE, VOL. 90, NO. 10, 25 MAY 2006 1311 livelihoods through marine fishing in the conservation of marine ecosystems, it was also evident that alternatives need to be formulated to minimize the growing pressure on these ecosystems. Providing incentives for prudent extraction of biological resources, sea farming and sea ranching were some of the suggestions made by the speakers. The pa...
In many physical, technological, social, and economic applications, one is commonly faced with the task of estimating statistical properties, such as mean first passage times of a temporal continuous process, from empirical data (experimental observations). Typically, however, an accurate and reliable estimation of such properties directly from the data alone is not possible as the time series ...
Urban structures in the form of pontoons and pilings represent major coastal habitats for marine organisms and understanding the factors causing abundances of organisms to differ between these and natural habitat has been neglected in the study of coastal ecology. It has been proposed that composition of substrata explain differences previously described between subtidal assemblages of epibiota...
Functional connectivity, the degree to which the landscape facilitates or impedes movement, depends on how animals perceive costs and benefits associated with habitat features and integrate them into a movement path. There have been few studies on functional connectivity in marine organisms, despite its importance for the effectiveness of Marine Protected Areas. In this study, we asked how open...
