Caring about the future


The basic concept of this indoor aquatic mesocosms facility is to provide a versatile system for experimental manipulation of environmental (chemical and physical) parameters and ecological scenarios, which may affect aquatic communities and ecosystem functional endpoints. This system is composed of 36 artificial channels and was developed to allow researchers to work over a wide range of configurations and address specific questions. Each system module is composed of three experimental glass channels (0.225 m high, 2.000 m long and 0.200 m wide) with a maximum functional volume of approximately 80 L, designed to be used either with or without sediment. The system can be operated in a flow-through or recirculated regime: being tanks connected to a common filtration pump (0.500 m high, 0.900 m long and 0.630 m wide), operating with a maximum functional water volume of approximately 280 L. The design allows the use of different pollutants, to control abiotic factors (water and air temperature, flow, water, chemistry, nutrition, photoperiod, light intensity, etc.) and to use statistically robust experimental designs (replication) for community ecology/ecotoxicology research.
