Characterization of aquatic ecosystems

One of the pillars in the management of aquatic ecosystems lies in the knowledge of their physical-chemical, hydromorphological and biological characteristics.

At IHCantabria we have extensive experience in the implementation, design and development of surveillance and monitoring programs in rivers, estuaries and coastal waters, ranging from field campaigns to the evaluation of water, sediment and biological community quality with different methodological approaches.

Among our areas of activity are the works dedicated to the characterization of different habitats (e.g. rivers, marshes, cliffs, dunes, intertidal and subtidal bottoms), and the different biological communities that make them up (phanerogams, macroalgae, fish, invertebrates and phytoplankton).

We currently have an accredited laboratory (IHBio) for field work and laboratory analysis, which has specialists in the taxonomic identification of fauna and flora.

The knowledge acquired allows us to analyze the response of biological communities to anthropogenic pressures and the role played by climatic variables, oceanographic and hydromorphological variables en theirspatial distribution and future evolution.

METHODOLOGY

We draw samples and analyse the physico-chemical, biological and hydromorphological characteristics of aquatic ecosystems.

We carry out taxonomic identification of macrophytes (phanerogams, algae), microalgae (phytoplankton, benthic diatoms), invertebrates and vertebrate fauna by using anatomical and genetic approaches (environmental DNA; eDNA).

We design and implement environmental monitoring and control programs.

We instrumentalize aquatic ecosystems and create web platforms for real-time monitoring (e.g. flows, water temperature)

We evaluate and diagnose the ecological and chemical status of aquatic ecosystems. We model at different spatio-temporal scales, modeling of water quality (e.g. nitrates), hydromorphological elements (e.g. flow) and bioindicator communities (e.g. invertebrates).

We develop bionomic mapping of terrestrial and aquatic communities.

We model potential habitat and species distribution.

We develop data analysis of the aquatic and climatic environmental variables.
