The effect of simulated heat-shock and daily temperature fluctuations on seed germination of four species from fire-prone ecosystems
(Soc Botanica Brasil, 2016-07-01)
Seed germination in many species from fire-prone ecosystems may be triggered by heat shock and/or temperature fluctuation, and how species respond to such fire-related cues is important to understand post-fire regeneration ...
Seedling survival of Handroanthus impetiginosus (Mart ex DC) Mattos in a semi-arid environment through modified germination speed and post-germination desiccation tolerance
(Int Inst Ecology, 2015-11-01)
Uniform rapid seed germination generally forms a great risk for the plant population if subsequent intermittent precipitation causes desiccation and seedling death. Handroanthus impetiginosus can be found commonly in a ...
Are wildfires affecting seed germination in cactus? An experimental assessment
(Wiley Blackwell Publishing, Inc, 2021-03-11)
Cacti are conspicuous plants across arid and semi-arid ecosystems of the American continent and are currently under threat due to human pressures, such as habitat loss, illegal collection and changes in fire regimes. ...
Non-native populations of an invasive tree outperform their native conspecifics
(Oxford University Press, 2016-10-13)
Introduced plants often face new environmental conditions in their non-native ranges. To become invasive, they need to overcome several biotic and abiotic filters that may trigger adaptive changes in life-history traits, ...
Fire and legume germination in a tropical savanna: ecological and historical factors
(2019-07-08)
BACKGROUND AND AIMS: In many flammable ecosystems, physically dormant seeds show dormancy-break patterns tied to fire, but the link between heat shock and germination in the tropical savannas of Africa and South America ...
Post-fire regeneration strategies in a frequently burned Cerrado community
(2021-01-01)
Aim: Fire is a natural disturbance in many ecosystems throughout the world where plant populations can persist by the resprouting of individuals and/or by recruiting from seeds. We evaluated the post-fire regeneration ...
Seed Pubescence and Shape Modulate Adaptive Responses to Fire Cues
(Public Library Science, 2016)
Post-fire recruitment by seeds is regarded as an adaptive response in fire-prone ecosystems. Nevertheless, little is known about which heritable seed traits are functional to the main signals of fire (heat and smoke), thus ...
O efeito do histórico do fogo na fenologia reprodutiva e atributos de sementes e germinação em espécies de Cerrado
(Universidade Estadual Paulista (Unesp), 2019-06-26)
No Cerrado, um dos fatores abióticos que influenciam na fenologia das plantas é o fogo, o qual é um distúrbio natural que interfere em diversos ecossistemas do mundo. O fogo altera as condições do habitat podendo ...
Ontogenic development of Guazuma ulmifolia (Sterculiaceae) sapplings
(Revista de Biologia Tropical, 1999-12-01)
Guazuma ulmifolia is as popular reforestation tree all over Latin America. It is characteristic of the initial stages of the secondary sucession and presents potential utility in the restoring of degraded areas. There is ...
