PANIC – Potamopyrgus antipodarum Invasion in Estarreja Rivers - a Climate Change Perspective
Invasive alien species pose a great risk to biodiversity and ecosystems services, a circumstance that is likely to worsen under a climate change scenario.
The New Zealand Mud Snail, Potamopyrgus antipodarum, a gastropod native to New Zealand, is one of the most successful freshwater invaders worldwide, due to a high reproductive potential combined with a wide tolerance range to physico-chemical parameters. In high densities, P. antipodarum can control nutrient cycling in aquatic systems and deeply alter the entire community structure and function. However, there is no information on the state of the invasion by this species in portuguese freshwaters, even in most susceptible areas, as Vouga River basin. Bridging this knowledge gap is critical to the implementing of functional and adequate management, control and mitigation plans.
The main objective of this project is to evaluate the invasion by Potamopyrgus antipodarum in Estarreja and its impacts on biodiversity, through the monitoring of macroinvertebrate communities from the main rivers. To predict future invasion success of the New Zealand Mud Snail under climate change scenarios, its tolerance to increase temperature and salinity will be tested.
