Short- and Mid-Term Spatiotemporal Diversity Patterns of Post-Fire Insect-Pollinated Plant Communities in the Mediterranean

open access: yesLand, 2023
In the Mediterranean, one of the most fire-prone regions in the world, wildfires are considered a key factor in vegetation distribution, structure, and function. Severe or frequent fires can lead to homogenized plant communities and habitat fragmentation

Flood and fire affect the soil seed bank of riparian forest in the Pantanal wetland

open access: yesRodriguésia, 2020
Flood and fire can harm plants but they can have survival strategies, such as the seed bank. We aimed to determine the influence of fire and flood on the richness, abundance and diversity of the seed bank.
