Onema and MNHN join forces for biodiversity

The National museum of natural history (MNHN) and Onema have joined forces to create synergies in an array of projects, including the European reporting system, characterisation reports on fish in France, the Nature and landscape information system (SINP), research on protected species, etc. One of the main reasons lies in the "fit" between the two knowledge bases that facilitates the production of new knowledge and implementation of public water policies.

Freshwater fish and climate change. Current situation and adaptation strategies

Knowledge for action series
What will be the consequences of climate change on the hydrology of aquatic environments? How will aquatic ecosystems and organisms react? What can be done to limit their vulnerability? Fish are emblematic life forms in rivers and an important resource for humans. The issue of the potential impact of climate change on fish species is therefore critical. This book in the Knowledge for action series reviews current knowledge on climate change and its consequences. A chapter addresses the adaptation measures compliant with current regulations that could, over the short and long terms, limit the vulnerability of freshwater fish and ecosystems.
