Post-fire resprouting strategies of woody vegetation in the Brazilian savanna [PDF]

, 2017
Post-fi re response by vegetation may refl ect the severity of the damage suff ered, but we still know little about the species-specifi c nature of responses to fi re or their predictors. Here, we evaluated 26 woody species before and after a fi re event

Taxonomy and diversity of Marcgraviaceae, north of the São Francisco river, northeast Brazil

Nordic Journal of Botany, Volume 2026, Issue 4, April 2026.
This study provides a comprehensive assessment of Marcgraviaceae species diversity north of the São Francisco river in northeastern Brazil, analyzing species richness and distribution patterns across 384 000 km² of phytogeographic domains. Through field collections, herbarium studies (both physical and digital), and detailed morphological analyses, we ...

Evaluation of randomized branch sampling for quantifying the production of fruits of caryocar brasiliense camb. (caryocaraceae) [PDF]

, 2012
Estudos sobre técnicas de amostragem adequadas e precisas para quantificar a produção de frutos de espécies nativas do Cerrado ainda são muito raros, o que configura uma lacuna para a formulação de Planos de Manejo Sustentáveis para o Bioma.

Seasonality as a structuring factor of the dung beetle community in burned neotropical savannas

Ecological Entomology, Volume 51, Issue 2, Page 336-345, April 2026.
We tested the effects of fire, vegetation cover and seasonality on dung beetle communities, focusing on species richness, composition and co‐occurrence patterns in savannas. Fire did not affect species richness. However, seasonality was the dominant factor influencing species composition, followed by fire and vegetation cover.

Protection status as determinant of carbon stock drivers in Cerrado sensu stricto

Journal of Plant Ecology, 2020
Abstract Aims Natural vegetation plays an important role in global carbon cycling and storage. Thus, the Cerrado (Brazilian savannah) is considered a carbon sink because of its intrinsic characteristics.

Viabilidade do Hidrogel na Recuperação de Cerrado sensu stricto com Espécies Nativas [PDF]

Floresta e Ambiente, 2017
RESUMO Este estudo determinou o custo e o efeito de polímero hidrorretentor (hidrogel) na redução da mortandade de mudas de seis espécies florestais nativas do Cerrado, na recuperação de área degradada em Planaltina – Distrito Federal. Foram testados quatro tratamentos (com e sem hidrogel nas estações seca e chuvosa) em delineamento em blocos ...

The role of habitat simplification and seasonality in shaping interactions between ants, plants and herbivores in a neotropical savanna

Ecological Entomology, Volume 51, Issue 2, Page 381-394, April 2026.
We evaluated how chronic anthropogenic disturbances (CAD) and seasonal variation influence interactions between ants and plants with extrafloral nectaries (EFN's), with emphasis on the responses of ants, herbivores, and plants. Ant and herbivore diversity remained stable across seasons in the preserved cerrado, whereas the pasture had higher ant ...
