A recent international review reveals the essential role of freshwater ecosystem engineers in the face of climate change. Co-authored by Professor Gemma Harvey from Queen Mary University of London, the study highlights how certain plants, animals, and insects change their environments. These changes can greatly influence how freshwater systems, such as rivers and lakes, respond to challenges like flooding and drought.
Many previous studies have focused on extreme weather events rather than temperature changes and drought. It’s crucial to shift our attention, as the impact of rising temperatures is becoming more severe. Interestingly, research has been largely centered in the U.S. and Europe, with areas expected to face significant climate changes receiving much less attention.
One surprising insight is that while we often think of larger species as major players in ecosystem changes, smaller organisms like insects and crustaceans also play significant roles. They may not be as charismatic, but their influence on ecosystems is vital.
Professor Harvey’s previous work, which assessed how various animals impact Earth’s landscapes, complements this new research. She emphasizes that freshwater ecosystems, crucial for biodiversity and human well-being, often get overlooked in climate conversations.
Recent statistics indicate that freshwater ecosystems are declining faster than terrestrial and marine systems. This makes understanding their dynamics even more pressing.
As climate change continues, recognizing how these ecosystems respond and the roles that different organisms play will be key for conservation and adaptation efforts.
