HALOBISE: Platform to understand the effects of the harmful algal bloom holobiont in a changing environment to predict their impact on aquatic ecosystem services

Climate change and anthropogenic pressure modify the aquatic dynamics and interacting factors that affect aquatic ecosystem function and services.

Harmful algal bloom (HAB) is one of the aquatic hazards increasing under such pressure in fresh, marine and brackish water bodies worldwide, threatening human health via food, recreation, tourism, wild animals in contact, and food security from aquaculture and fisheries.

Our prediction capabilities could still not respond to a changing environment with efficient management of the impact of HAB in aquatic ecosystem services.

The HAB holobiont, microbiome-attached, and free-living bacteria interactions mutually contribute via metabolic complementation to support the propagation during HAB development and decline.

Introducing the holobiont dynamics would offer a better understanding of the development and termination of HAB events, providing a missing link between available data from monitoring programs and a more accurate interpretation of the impact of HABs in ecosystem services.

The overall objective of HALOBISE is to provide high-quality knowledge from the HAB holobiont that tackles the biological and sociological complexity of HABs to improve the predictive capacities of aquatic monitoring programs and to implement instruments for governance that will enhance their management capabilities to mitigate the impact of HABs on ecosystem services in the context of multiple pressures in a changing environment.
