Functional ecological patterns and the effect of anthropogenic disturbances on a recently restored Mediterranean coastal lagoon. Needs for a sustaina…
2012
Abstract We present here a detailed case study on the lessons learned after a restoration process of a natural ecosystem, which can be considered as an ecological experiment. Senillar de Moraira is a brackish water small coastal lagoon located in the Spanish Mediterranean coast. It is separated from the sea by a sand bar and a beach, and is regularly fed by groundwater. Mostly due to the strong anthropogenic pressure this lagoon was degraded, and a restoration process, consisting mostly on the rebuilt of hydrogeomorphological features, was accomplished about a decade ago. After the restoration project, ecological monitoring was performed to reveal the recovery of the ecological integrity of…
The relevance of ecological status to ecosystem functions and services in a large boreal lake
2014
Summary Environmental conventions aim to protect ecosystem structures and functions to provide goods and services for mankind. The degree of aquatic ecosystem naturalness, or ecological status as it is defined in the Water Framework Directive (WFD) of the European Union, is notionally linked to supplies of ecosystem services. In practice, these links have rarely been documented or even investigated, and to justify conservation and management objectives based on the status indicators, it is essential to demonstrate their relationships to ecosystem functions and services. The WFD requires member states to classify their surface waters aiming to achieve good ecological status of water bodies. …
ECOLOGICAL ASSESSMENT AS A FIRST STEP IN THE EVALUATION OF ECOSYSTEM SERVICES PROVIDED BY LOTIC ECOSYSTEMS
2013
ABSTRACT The ecosystems offer to the socio-economic system a series of goods and services derived from their processes and biodiversity. Ecosystem services offered by a river are at their highest potential when the river status is close to the natural one. Once the river is affected by human impact due to resources exploitation, hydro technical works, water abstraction or improper land use, the ecological status declines and the ecosystem services become scarce. This is why an ecological assessment is necessary in order to establish the connection between the ecosystem services and the human impact. In this paper, the ecological assessment of Timiș River was done, allowing the classificatio…
