Urbanisation alters the natural hydromorphology of streams, affecting aquatic communities and ecological quality. Increasing efforts have been put into rehabilitation urban streams due to their importance for sustainability. Despite these efforts, many projects fail achieve improvement communities. This study aims provide specific recommendations enhance biological by reviewing: (i) impacts urb...

Headwater species and peripheral populations that occupy habitat at the edge of a species range may hold an increased conservation value to managers due to their potential to maximize intraspecies diversity and species' adaptive capabilities in the context of rapid environmental change. The southern Appalachian Mountains are the southern extent of the geographic range of native Salvelinus fonti...

CAUSES AND FUNCTIONAL CONSEQUENCES OF DENITRIFYING BACTERIA COMMUNITY STRUCTURE IN STREAMS AFFECTED TO VARYING DEGREES BY WATERSHED URBANIZATION by

A stream is a sequence of data indexed by time. The behaviour of natural and artificial systems can be modelled by streams and stream transformations. There are two distinct types of data stream: streams based on continuous time and streams based on discrete time. Having investigated case studies of both kinds separately, we have begun to combine their study in a unified theory of stream transf...

Effective watershed management requires accurate modeling of river discharge. Many years of data collection are often required to capture variations in seasonal trends and produce accurate predictive and descriptive models. In this study artificial neural networks that employ inductive transfer are used to develop models that predict the discharge (flow rate) of streams in Nova Scotia from weat...

The ecology of viruses has been studied only in a limited number of rivers and streams. In light of a recent re-appraisal of the global fluvial surface area, issues such as abundance and production, host mortality and the influence of suspended particles and biofilms are addressed. Viral life cycles, potential impacts of viruses on water biochemistry and carbon flow, and viral diversity are con...

We conduct and analyze two large surveys of hypothetical annuitization choices. We find that allowing individuals to annuitize a fraction of their wealth increases annuitization relative to a situation where annuitization is an "all or nothing" decision. Very few respondents choose declining real payout streams over flat or increasing real payout streams of equivalent expected present value. Hi...

Recently, ontology stream reasoning has been introduced as a multidisciplinary approach, merging synergies from Artificial Intelligence, Database and World-Wide-Web to reason on semantics-augmented data streams, thus a way to answering questions on real time events. However existing approaches do not consider stream change diagnosis i.e., identification of the nature and cause of changes, where...

Clinical practice and research are facing a new challenge created by the rapid growth of health information science and technology, and the complexity and volume of biomedical data. Machine learning from medical data streams is a recent area of research that aims to provide better knowledge extraction and evidence-based clinical decision support in scenarios where data are produced as a continu...
