Frost Decreases Fruit Production in a Neotropical Savanna: Implications for Frugivorous Bird Abundances

Biotropica, Volume 58, Issue 3, May 2026.
Severe frost events seem to be happening on average every 5 years, rather than 7 years, as previously reported in the southern limit of the Cerrado, a Neotropical savanna. We conducted this study in the Cerrado, where severe frost events allowed us to compare fruit production and frugivorous bird abundance before and after the disturbance.

An inverse latitudinal gradient in intraspecific genetic diversity of a dominant ant in the neotropical savanna

Ecosphere, Volume 17, Issue 4, April 2026.
Abstract Although latitudinal gradient of diversity (LGD) is a biogeographic pattern widely shown for distinct animal groups, some display the opposite pattern, with biodiversity peaking away from the equator. These inverse gradients may result from drivers that also overlap with extrinsic factors shaping genetic diversity across taxa, a level of ...

Vascular Flora of a Cerrado sensu stricto remnant in Pratânia, state of São Paulo, southeastern Brazil

Check List, 2010
The Cerrado (Brazilian savanna) has suffered massive destruction in recent years, mainly due to the expansion of agricultural areas. Many remnants of this vegetation are still poorly studied. Therefore, the purpose of this study was to carry out a floristic survey in a remnant of Cerrado in the municipality of Pratânia, central-west region of state of ...

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 ...

Modelos hipsométricos ajustados para um fragmento de cerrado Sensu stricto tocantinense [PDF]

Revista Agrogeoambiental, 2019
Para uma redução dos custos de inventário florestal, os modelos hipsométricos são de grande valia. O presente trabalho teve como objetivo ajustar e avaliar modelos de relação hipsométrica em área de Cerrado em processo regenerativo situada no município de Gurupi (TO). Foram testados dez modelos, incluindo cinco lineares e cinco não lineares, no qual os

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.

Carbon Stocks in Compartments of Soil Organic Matter 31 Years after Substitution of Native Cerrado Vegetation by Agroecosystems

Revista Brasileira de Ciência do Solo, 2016
Changes in carbon stocks in different compartments of soil organic matter of a clayey Latossolo Vermelho Distrófico (Typic Haplustox), caused by the substitution of native savanna vegetation (cerrado sensu stricto) by agroecosystems, were assessed after ...
