Ecological continuity in littoral wetlands, a local, national and European issue - n° 41 | Rencontres |
Questions concerning littoral wetlands are being raised during a time of transition impacted by both natural phenomena (e.g. the infl uence of climate change on littoral wetlands) and institutional changes. In this highly fl uid context, the objective is to produce a joint project for the Atlantic, Mediterranean and Channel/North Sea coasts, based on a shared vision of the issues.
Guide to scale interpretation and age estimation for Atlantic Salmon (Salmo salar) from French populations | Guides et protocoles |
Belonging to the genus Salmo, the Atlantic Salmon is a species in the family Salmonidae and the subfamily Salmoninae. The Atlantic Salmon is still present in numerous rivers of the French Channel-Atlantic seafront. It has always been absent from the Mediterranean. The overall objective of this guide is to serve as a user manual for interpreting the scales and estimating the age of the Atlantic Salmon (Salmo salar) from the French Atlantic Salmon populations.
LIFE WolfAlps EU 2022 Conference: Is the grass always greener elsewhere? N° 90 | Rencontres |
After having been exterminated in certain countries, the wolf is returning naturally and extending its territory on the continent, not without generating tensions. Managing this conflictual situation has become a major issue. How do our European neighbours manage cohabitation with the predator? Twelve experts representing seven European countries provided some partial answers.
The ICE protocol for ecological continuity - Assessing the passage of obstacles by fish. Concepts, design and application | Comprendre pour agir |
Obstacles to flow in rivers constitute a major source of breaks in ecological continuity. Given the vast array of regulatory requirements, notably the Water framework directive, and the many environmental issues involved in restoring the ecological continuity of aquatic environments, Onema decided to create a "tool" to assess and quantify the impacts of hydraulic structures on the free movement of fish.
Guide to the interpretation of the scales and the estimation of the age of brown trout (Salmo trutta) from the French populations | Guides et protocoles |
Three biological forms of brown trout, river, lake and sea, have colonised a large number of aquatic environments in France, owing to a high ecological plasticity of the species. The overall objective of this guide is to serve as a user manual for interpreting the scales and estimating the age of brown trout (Salmo trutta) from the French trout populations.
