The PLANAQUA platform: a cutting-edge experimental infrastructure for multi-scale studies on aquatic ecosystems
Résumé
The "PLAteforme expérimentale Nationale d'écologie
AQUAtique" is a multi-scale experimental infrastructure created in 2011
to make possible the analysis of human disturbance on aquatic
biodiversity, community structure, and ecosystem functioning. It is
funded by the "Investissements d'avenir Equipex" program and is partner
of the ANAEE-France research infrastructure. PLANAQUA provides the
scientific community with access to experimental highly instrumented
platforms available year round through calls for projects open to all
researchers around the world. It includes: 1) Microcosms (1-6 L),
developed for studying plankton ecology and physiology under highly
controlled environmental conditions in the dedicated laboratory or in
the climatic rooms of the Ecotron IleDeFrance. Organisms and ecosystems
activity and dynamics are precisely monitored by a series of dedicated
sensors and instruments. 2) Mesocosms (1-15 m3), have a high degree of
replication. They are installed outdoors and can house complex
communities of organisms. Among them a series of twelve is equipped with
beaters that generate waves, making possible to control the physical
structure of the water column thus to study the link between physical
constraints and functioning of aquatic systems. 3) Macrocosms, sixteen
artificial lakes (650 m3) dedicated to understand the functioning of
complex natural communities with heterogeneous spatial distributions;
they will allow ascertaining the consequences of anthropogenic pressures
on biodiversity, up to the top of the food chains. They are equipped
with automated sensors and data loggers for high-frequency data
collection of the main physical-chemical parameters. PLANAQUA is located
at the CEREEP research center (CNRS-ENS, UMS 3194) near Paris.
