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.

Songbird response to wildfire in mixed-conifer forest in south-western Oregon
Year: 2014
We used 1 year of pre-fire and 4 years of post-fire data to quantify changes in the occurrence of birds at burned and unburned sites in a southern Oregon watershed after a 2500-ha wildfire. Our objectives were to identify bird species that increased or decreased as a result of this mixed-severity fire. Of the 27 species we investigated, we found evidence for fire-induced changes in the proportion of sites occupied by 13 species. Of these, most (8 species) were species that occurred at fewer sites after the fire than before. These changes were consistent with changes in vegetation composition…
