Distribution and vulnerability to climate change of the aquatic macroinvertebrates of the Canary Islands

This project focuses on the aquatic insect fauna of the Canary Islands archipelago, which is especially interesting for three reasons: 1) it is little known due to the lack of inventories and scientific studies; 2) includes a large number of endemisms; 3) presents a great vulnerability to hydric stress derived from climate change. The project has four specific objectives: 1) Hydrologically characterize the main bodies of surface water; 2) Generate basic information on the taxonomic and genetic diversity of aquatic macroinvertebrates; 3) Determine the vulnerability of species to global climate change; 4) Identify the priority zones for the conservation of the biodiversity of aquatic insects. Thus, this project will serve to establish basic knowledge about the aquatic biodiversity of the Canary Islands, which includes a large number of endemic species, and to promote conservation strategies in anticipation of the effects of climate change.

Conservación de la biodiversidad acuática en los Parques Nacionales de las Islas Canarias en un contexto de estrés hídrico y especies invasoras

Freshwater biodiversity is disappearing at an accelerated rate as a result of human activities. This situation is especially alarming in regions of the planet where water scarcity derived from human demand and climate change pose a risk to a large number of species. This can even lead to the loss of species that have not yet been described. In this context, protected areas play a fundamental role as reservoirs of biodiversity, which needs to be properly studied to guarantee its preservation. This project focuses on the aquatic biodiversity of three National Parks of the Canary Islands archipelago (Teide, Garajonay and Caldera de Taburiente), which is especially interesting for three reasons: 1) it is poorly described due to the lack of inventories and studies scientists; 2) it includes a large number of endemisms; and 3) it presents a great vulnerability to water scarcity. The objectives of the project are to:
1) Hydrologically characterize the main surface water bodies;
2) Generate basic information on the taxonomic and genetic diversity of the communities of aquatic insects and diatoms;
3) Evaluate the current status of aquatic invasive species;
4) Determine the vulnerability of the species to climate change; and
5) Identify priority areas for the conservation of biodiversity and for the management of invasive species in a context of water stress and climate change.
Among other things, the CONACAN project will serve to design a sampling network for aquatic biodiversity within the parks studied, to train park personnel in its study and conservation, and to propose conservation
measures for biodiversity and the management of invasive species.
