Native remnants can be sources of plants and topsoil to restore dry and wet cerrado grasslands

NAL Pilon, GB Assis, FM Souza… - Restoration Ecology, 2019 - Wiley Online Library
Neotropical grasslands have undergone intensive degradation by land conversion or
biological invasion, but their restoration is still challenging. Here, we integrated two …

How does fire affect germination of grasses in the Cerrado?

M Dairel, A Fidelis - Seed Science Research, 2020 - cambridge.org
Fire is a frequent disturbance in the Cerrado and is one of the major factors affecting
vegetation structure and diversity. Fire events open gaps within the herbaceous layer and …

Fire cues trigger germination and stimulate seedling growth of grass species from Brazilian savannas

DM Ramos, JFM Valls, F Borghetti… - American Journal of …, 2019 - Wiley Online Library
Premise Although fire cues (high temperatures and smoke) influence seed germination in
numerous species from fire‐prone environments, their effects on seed germination of …

Fire has contrasting effects on the survival, growth, and reproduction of Cerrado grasses with differing regenerative strategies

HGV Fontenele, HS Miranda - Applied Vegetation Science, 2024 - Wiley Online Library
Background Cerrado grasses are closely linked to fire, but the mechanisms underlying their
responses are poorly understood. Fire affects populations by altering vital rates, and …

Seed ecology of post-fire flowering species from the Cerrado

HGV Fontenele, HS Miranda - Seed Science Research, 2022 - cambridge.org
