Abstract: – The highly diverse ichthyofaunas of Southeast Asian fresh waters are threatened by land-use change, resulting in declines in species richness. Given the ecological importance of freshwater fishes, the loss of their diversity is expected to alter ecosystem functioning—i.e., pools and fluxes of biogeochemical resources—but these potential impacts remain poorly understood in Southeast Asia. To address this knowledge gap, I aim to elucidate the relationship between freshwater fish diversity, ecosystem functioning and land-use change in Southeast Asia.
By characterising and analysing the variation in functional traits of freshwater fishes, my work will investigate mechanistic links between freshwater fish diversity and the ecosystem functions mediated by them. I will also conduct both cross-sectional and longitudinal field studies across Southeast Asia to quantify the impacts of land-use driven fish diversity losses on the functioning of flowing fresh waters in the region. Since ecosystem functions ultimately underpin ecosystem services that are essential for human well-being, knowledge gained from this study will help illuminate the potentially far-reaching and reflexive consequences of anthropogenic biodiversity loss.
