Spatiotemporal dynamics of forest geometrid outbreaks

Area of Science:

• Ecology
• Entomology
• Climate Change Science

Background:

• Forest geometrid moths (Geometridae) exhibit traits making them susceptible to climate change-driven range expansions and host shifts.
• Recent shifts in geometrid spatiotemporal dynamics present research opportunities to study spatial synchrony drivers.
• Understanding these dynamics is crucial for forest ecosystem management.

Purpose of the Study:

• To review recent advancements and future directions in understanding forest geometrid spatiotemporal dynamics.
• To explore the role of climate change, biological traits, and trophic interactions in geometrid population changes.
• To advocate for the application of near-term ecological forecasting in geometrid research.

Main Methods:

• Literature review of recent developments in geometrid population dynamics research.
• Analysis of factors influencing spatial synchrony, including biological traits and trophic interactions.
• Discussion of the potential of near-term ecological forecasting for predicting geometrid outbreaks.

Main Results:

• Forest geometrids are particularly vulnerable to climate change, leading to altered spatiotemporal dynamics.
• Observed changes offer opportunities to test hypotheses on spatial synchrony and its drivers.
• Near-term ecological forecasting shows promise for predicting geometrid population dynamics.

Conclusions:

• Climate change significantly affects forest geometrid populations, necessitating advanced predictive tools.
• Further research into biological traits and ecological interactions is vital for understanding geometrid dynamics.
• Near-term ecological forecasting can provide accurate predictions and mechanistic insights for forest geometrid management.
