Ecosystems require access to key nutrients like nitrogen (N) and sulfur (S) to sustain growth and healthy function. However, excessive deposition can also damage ecosystems through nutrient imbalances, leading to changes in productivity and shifts in ecosystem structure. While…

The evolutionary role of fire in animals has been poorly explored. Reptiles use sensory cues, such as smell (chemoreception), to detect threats and flee. In Mediterranean ecosystems, fire is a threat faced by reptiles. We hypothesized that the Mediterranean lizard Psammodromus…

Fire increases seedling recruitment by reducing competition for space and resources. As such, many species in fire-prone ecosystems germinate in response to fire cues such as smoke and heat. A notable exception is fire-prone temperate grassy ecosystems, where >20 yr of…
