Cattle decrease plant species diversity in protected humid temperate savanna
(Gebruder Borntraeger, 2018-08-17)
Question: Is domestic cattle an appropriate surrogate for fire in a protected humid temperate savanna? Study area: El Palmar Grande de Colón (31°52' S, 58°17' W), Argentina. Methods: We surveyed dense Butia yatay palm ...
Thresholds of fire response to moisture and fuel load differ between tropical savannas and grasslands across continents
(2020-02-01)
Aim: An emerging framework for tropical ecosystems states that fire activity is either “fuel build-up limited” or “fuel moisture limited”, that is, as you move up along rainfall gradients, the major control on fire occurrence ...
Palynomorphs from a Recent Soil Covered with a Savanna-Like Vegetation in Caxiuanã, Pará, Brazilian Amazon

Rare frost events reinforce tropical savanna–forest boundaries
(2018-01-01)
The ability of vegetation to ameliorate or exacerbate environmental extremes can generate feedbacks that mediate the distribution of biomes. It has been suggested that feedbacks between vegetation and frost damage may be ...
Metabolomics of Myrcia bella populations in Brazilian Savanna reveals strong influence of environmental factors on its specialized metabolism
(2020-06-01)
Environmental conditions influence specialized plant metabolism. However, many studies aiming to understand these modulations have been conducted with model plants and/or under controlled conditions, thus not reflecting ...
Fire frequency alone does not explain forest - savanna transition: the role of dry season precipitation variability in northern South America
(Grupo de Ingeniería y Gestión Ambiental (GIGA)Medellín, 2022)
Thirty years of clear-cutting maintain diversity and functional composition of woody-encroached Neotropical savannas
(2021-08-15)
Humans have changed vegetation dynamics in Neotropical savannas by suppressing fires, allowing trees and shrubs to expand into ancient savanna landscapes in a process known as woody encroachment. This woody encroachment ...
