Evidence

Peer-reviewed

Geography

Nineteen Cornitermes cumulans colonies in São Paulo state, Brazil

System

Savanna termite mounds, thermal physiology and climate risk

## WHAT THE EVIDENCE SAYS

Across 19 colonies, the investigators measured worker thermal tolerance and trait variation; internal nest microclimates were monitored in four mounds. Nest temperatures fluctuated less than ambient air, and modeled present-day thermal safety margins remained positive. Warming scenarios projected narrower margins, especially toward lower latitudes, while worker morphology and aspects of gut function varied with climatic gradients.

## WHY IT MATTERS / OUR READ

Animals can buffer exposure by constructing habitat without becoming ecologically independent of climate. Conservation and land-use decisions that protect microhabitats still need to consider chronic warming and biological functions beyond simple survival thresholds.

## CAVEATS / UNCERTAINTY

Only four mounds had direct temperature time series, while future safety margins are model projections based on assumptions about behavior and physiology. Gut-microbiome associations do not demonstrate effects on colony performance; this is not evidence that all termite species share the same buffer.
