Ludi Parwadani Aji

Ludi

I am a postdoctoral fellow at Naturalis Biodiversity Center, The Netherlands, under the supervision of Dr. Lisa Becking, and a staff at the National Research and Innovation Agency, Indonesia (BRIN). I am a marine ecologist and do research on the impact of anthropogenic pressure on coastal ecosystems. I use marine lakes as a natural laboratory to predict the impact of increasing temperature and terrestrial influence on biodiversity and food web structure.

A major challenge in marine science is understanding how coastal tropical marine organisms will respond to environmental disruptions caused by increasing seawater temperature and high terrestrial effluent. Those disturbances in tropical coastal ecosystems can lead to a decline in coral cover. A shift from coral-dominated states to non-coral dominated states may reduce biodiversity and can disrupt interactions among various species within the ecosystem. Such disruptions can also impact the energy transfer between trophic levels via food chains and affect the structure of food webs within these ecosystems. 

This can harm fisheries, coastal protection, and other ecosystem services. I use marine lakes as model systems to understand the impact of changing environmental conditions on tropical coastal ecosystems. Marine lakes, small landlocked bodies of marine water, represent natural settings for various predicted environmental scenarios, including increased water temperature and low water quality. I investigate the potential impacts of increasing temperatures and terrestrial influences on the biological diversity, benthic community structure, and food web dynamics of tropical coastal ecosystems.
