Biodiversity Science Lab
Machine-translated · View original
A lab that uncovers how ecosystem balance works by studying the interactions between organisms and their environment.

AboutAbout the lab
The science of biodiversity
The Biodiversity Science Lab studies the mechanisms that maintain and disrupt ecosystem balance, focusing on the interactions between organisms and their environment.
Ecosystems have the capacity to recover from a certain degree of disturbance, but in recent years biodiversity has been disappearing at a rate that exceeds this limit.
Building on ecology, the lab works to clarify and predict how the abundance and diversity of organisms, the structure of food webs, and other features will change.
The lab shares its findings with the world through papers, and also delivers them to society as concrete recommendations for protecting and managing ecosystems and biodiversity.
Key terms
- food web
- The whole of the "eating and being eaten" relationships among organisms, connected in a complex, net-like structure
- pollination service
- The function by which insects and other animals carry pollen, helping crops and plants bear fruit. One of the benefits people receive from nature
- regime shift
- A phenomenon in which the structure or functioning of an ecosystem abruptly changes to a different state
ResearchResearch themes
The lab aims to uncover and predict the mechanisms that maintain and disrupt ecosystem balance, by studying the interactions between organisms and their environment. Its work covers reconciling rare species conservation with agriculture, managing invasive species and wildlife, theory on the evolution of biodiversity, and the mechanisms by which ecosystems persist amid human activity.
*Illustrative imageReconciling Rare Species Conservation and Agriculture
The lab conducts research on reconciling agriculture with the protection of the endangered Miyama-shijimi butterfly, and on landscape management that keeps buckwheat yields (pollination services) stable.
*Illustrative imageManaging Invasive Species and Wildlife
Among invasive species, the lab studies the problem of feral cats, which particularly affect island ecosystems, focusing on the relationships among organisms and their connections to human activity.
*Illustrative imageTheory on the Evolution of Biodiversity
This research explores, from a theoretical perspective, how biodiversity changes through evolution from the past into the future.
*Illustrative imageHow Ecosystems Persist Amid Human Activity
To predict in advance when human activity will cause regime shifts in ecosystems, the lab develops early warning signals using deep learning trained on data generated by simulations.
