The 13th FSEGG seminar（2024）
July 3rd (Thu), 16:30-17:30, room N31, Faculty of Agriculture, Hokkaido University
“Dynamic change of biological interactions and its consequences in ecological systems"
speaker:
Minoru Kasada, Ph.D., Assistant Professor (Field Science Center, Hokkaido University)
Interactions between biological organisms are changing with time and circumstances. This dynamic change of biological interactions affects ecological consequences such as biodiversity, community composition and population dynamics. In addition, the dynamic change of biological interactions is strongly influenced by the ecological consequences because they have similar time scales. Therefore, feedbacks between the biological interactions and the ecological consequences are expected to influence each other. This results in dynamically changing ecological networks. A number of interesting phenomena and theories triggered by these dynamic ecological networks have become known and studied in recent years. In this presentation, I will give an overview of the causes of the dynamic change of biological interactions and present examples of the relationships and feedbacks between the biological interactions and the ecological consequences, focusing on researches we have investigated.
