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
(Instituto de Geociências /Universidade Federal do Rio Grande do Sul, 2001)
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 ...
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 ...
Cerrado vegetation and global change: the role of functional types, resource availability and disturbance in regulating plant community responses to rising CO2 levels and climate warming
(Brazilian Soc Plant Physiology, 2014-03-01)
The cerrado is the most extensive savanna ecosystem of South America and a biodiversity hotspot, harboring a diverse flora ([7,000 species) with high levels of endemism. More than 50 % of the cerrado's approximately 2 ...
The role of bud protection and bark density in frost resistance of savanna trees
(Wiley-Blackwell, 2019-10-16)
Frost events occur with a significant frequency in savannas of the Southern Hemisphere, especially in the Cerrados of Brazil. One of the main strategies to deal with such events is to invest in thick and dense bark, which ...
A synopsis of sloanea (Elaeocarpaceae) in the neotropical extra–amazonian region
(2016-07-01)
The genus Sloanea is comprised of 150 species, of which about 50 occur in Brazil among several vegetation types but mainly the Amazon and Atlantic forests. The present work provides a synopsis of the Neotropical species ...
