Abstract The Pechora Bay is a hydrologically and ecologically important area of the Barents Sea but there are still gaps in our knowledge biodiversity area, including macrozoobenthos. In first half twentieth century, was noted as type locality for bivalve mollusc Portlandia aestuariorum . Only few surveys macrozoobenthos have been conducted since last work from this indicated absence P. paper, ...

An ecological index of macrobenthic communities is an important tool for assessing the biological quality habitats and ecosystems. We tested performance inverse function Shannon–Wiener evenness proportion (ISEP) with data from entire west coast Korea, seasonally sampled 2006 to 2008. Two validations were performed: (1) examination relationship between ISEP environmental factors (2) corresponden...

Saltmarsh is one of the most productive coastal habitats in marine environment, and macroinvertebrate community crucial to its ecology productivity. These ecosystems are currently under threat due climate change anthropogenic activities. However, communities their functionality saltmarsh from subtropical areas have previously been largely ignored. In this study, we aimed elucidate (i) diversity...

We assessed the effect of a hydropeaking diversion mitigation measure that allows for additional hydropower production, which markedly reduced on 10-km stream reach in north-eastern Italian Alps. Hydropeaking, caused by storage plant, affected study from 1920s to 2015, when cascade three small run-of-the-river plants was installed divert hydropeaks plant outlet directly into intake RoRs plants,...

Background. Healthy shellfish populations are important to the proper function of estuarine ecosystems. Estuaries like Chesapeake Bay once held large numbers of American oysters (Crassostrea virginica). Historically, these oysters filtered the entire bay’s water volume every 3.3 days. Several centuries of over exploitation compounded by diseases such as Perkinsus marinus and MSX, coupled with w...

Modelling arguments on the social web is a key challenge for those studying computational argumentation. This is because formal models of argumentation tend to assume dialectic and logical argument, whereas argumentation on the social web is highly eristic. In this paper we explore this gap by bringing together the Argument Interchange Format (AIF) and the Semantic Interlinked Online Communitie...

Large volumes of content (bookmarks, reviews, videos, etc.) are currently being created on the “Social Web”, i.e. on Web 2.0 community sites, nd this content is being annotated and commented upon. The ability to view an individual’s entire contribution to the Social Web would be an nteresting and valuable service, particularly important as social networks are often being formed through created ...
