The theme of this conference is "Rivers and Lakes under Multiple Stressors". Freshwater ecosystems provide critical functions and services, but they are facing accelerated degradations globally under multiple stressors, such as eutrophication, emergent pollutants, climate change, habitat alteration, water diversion and biological invasions. These multiple stressors can interact and impact the physical, chemical, and biological processes of freshwater ecosystems, but the mechanisms of their combined effects are not yet clearly understood.

The study of limnology urgently requires the development of new methods and the conduct of multifactorial, complex system, and large-scale research. This will provide scientific guidance for the better restoration and management of these fragile ecosystems. Therefore, the main objective of ISRLE 19 is to provide a forum for discussion of the latest advancements in limnology of rivers and lakes under multiple stressors, as well as the opportunities and challenges faced, and to enhance academic exchanges between the limnology community across international counterparts. To encourage cross-community connections, ISRLE 19 will include a series of sessions grouped into 6 sub-themes such as:

Sub-theme 1: Responses of freshwater ecosystems to multiple stressors

Sub-theme 2: Trophic interactions and food web structures

Sub-theme 3: Biodiversity and ecosystem functioning

Sub-theme 4: New research methods and techniques in limnology

Sub-theme 5: Opportunities and challenges in collaborative limnological research

Sub-theme 6: Lake management and public science
