Finding floral and faunal species richness optima among active fire regimes

Year: 2025
Changing fire regimes have important implications for biodiversity and challenge traditional conservation approaches that rely on historical conditions as proxies for ecological integrity. This historical-centric approach becomes increasingly tenuous under climate change, necessitating direct tests of environmental impacts on biodiversity. At the same time, widespread departures from historical fire regimes have limited the ability to sample diverse fire histories. We examined 2 areas in California's Sierra Nevada (USA) with active fire regimes to study the responses of bird, plant, and bat…

Showy dragonflies are being driven extinct by warming and wildfire

Year: 2025
Rising temperatures may disrupt reproduction before becoming lethal; thus mating traits could define species vulnerability to warming. Here, using >1,600 estimates of local extinction for 60 dragonfly species, we show that species with mating-associated wing ornamentation experienced more extinctions and lost more habitat under warming and following wildfire burn than non-ornamented species. By contrast, sensitivity was not affected by ecological traits, such as thermal limits, habitat specialization or body size.

Fire in focus: Clarifying metrics and terminology for better ecological insight

Year: 2025
  1. Changing fire regimes are profoundly impacting ecosystems and society, requiring rapid advancement in fire-related knowledge within and across disciplines. Given the influx of new disciplines into the fire field, a lack of transparent vocabulary for the application and interpretation of fire regime attributes and fire metrics impedes the capacity to scale ecological knowledge across ecosystems and continents.
  2. In this article, we acknowledge there are many ways to define or measure fire metrics, but demonstrate how precision and context are important for interpreting fire…
