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.

Going slow to go fast: landscape designs to achieve multiple benefits

Year: 2025

Introduction: Growing concerns about fire across the western United States, and commensurate emphasis on treating expansive areas over the next 2 decades, have created a need to develop tools for managers to assess management benefits and impacts across spatial scales. We modeled outcomes associated with two common forest management objectives: fire risk reduction (fire), and enhancing multiple resource benefits (ecosystem resilience).Method: We evaluated the compatibility of these two objectives across ca. 1-million ha in the central Sierra Nevada,…
