Populations of insects, trees or crops in distant places sometimes rise and fall together, a pattern called spatial synchrony. Explaining why this happens is hard.

What they work on

  1. Apply Ising universality, a statistical-physics idea that simple aligned-state models capture many systems' behavior, to ecological data coarse-grained into a few population states, to study synchrony independent of system details.
  2. Use machine learning on remotely sensed orchard data to uncover how real patterns of synchrony arise across space and over multiple time scales.
  3. Build mechanistic models of intermediate complexity that link the Ising description to the machine-learning results, to validate and improve both approaches.
  4. Predict which features of ecological systems promote or prevent spatial synchrony, with attention to transient dynamics and robustness to noisy data.

More about the research

Ecological data are often noisy and coarse, and real systems may spend much of their time in temporary (transient) states rather than settling into long-run behavior. Understanding what drives synchrony matters more as a changing climate reshapes ecosystems. It is also relevant to conservation, agriculture and public health.

Why it matters

Knowing what makes populations fluctuate in step across a landscape could improve conservation planning and agricultural practice, for example in orchard management. It could also help predict how ecosystems respond to a changing climate. Universal rules for how spatial patterns form may also offer insight in public health, where synchrony and spatial spread matter.
