Exploring the Discrepancies in the Biological Activities of Extracts From Guadua angustifolia Var. Bicolor Londoño Collected in Two Different Sites. [PDF]

Chem Biodivers
ABSTRACT Guadua angustifolia var. bicolor Lodoño is a Colombian bamboo species that has shown promising medicinal properties. This study aims to investigate the differences in the chemical composition and biological activity of extracts from two different populations of G. angustifolia var. bicolor, collected in Bauru and Tatuí, Brazil.

Past human‐induced ecological legacies as a driver of modern Amazonian resilience

People and Nature, Volume 5, Issue 5, Page 1415-1429, October 2023., 2023
Abstract People have modified landscapes throughout the Holocene (the last c. 11,700 years) by modifying soils, burning forests, cultivating and domesticating plants, and directly and indirectly enriched and depleted plant abundances. These activities also took place in Amazonia, which is the largest contiguous piece of rainforest in the world, and for

Combining target enrichment and Sanger sequencing data to clarify the systematics of the diverse Neotropical butterfly subtribe Euptychiina (Nymphalidae, Satyrinae)

Systematic Entomology, Volume 48, Issue 4, Page 498-570, October 2023., 2023
We present a molecular phylogeny of the Neotropical butterfly subtribe Euptychiina, including 449 described and undescribed species By using a combination of target enrichment and Sanger sequencing data we avoid long‐branch attraction effects and clarify the systematics of the clade.

Ecological legacies of past fire and human activity in a Panamanian forest

PLANTS, PEOPLE, PLANET, Volume 5, Issue 2, Page 281-291, March 2023., 2023
Tropical forests provide global ecosystem services and harbor much of Earth's terrestrial biodiversity, but the mechanisms driving the patterns of biodiversity remain uncertain. Palms are one of the most abundant and most widely used plant groups, particularly in the Neotropics.

Hydrogeological Challenge for Coal Bed Methane (CBM) Production in Structurally Complex Reservoirs: Case Study for the Synclines of Umbita and Checua‐Lenguazaque, Colombia

Journal of GeoEnergy, Volume 2023, Issue 1, 2023., 2023
Colombia is advancing toward pilot production of coal bed methane (CBM) at the Umbita syncline (US) and Checua‐Lenguazaque syncline (CLS) in the Cundiboyacense plateau of the Eastern Cordillera. Although attractive, the development of CBM resources remains hydrogeologically challenging due to infinite acting aquifer (IAA) conditions, a sustainable ...

Investigating the impacts of biochar on water fluxes in a rice experiment in the dry corridor of Central America, Costa Rica

Hydrological Processes, Volume 36, Issue 12, December 2022., 2022
How does biochar impact soil water storage? After adding biochar to an upland rice field in Costa Rica, we observed a shift in the soil water retention curves, indicating that rice plants had 2%–7% more water available. The isotopic composition of plant water did not vary with biochar, indicating rice plants likely consumed similar water.

Bamboo climatic tolerances are decoupled from leaf functional traits across an Andean elevation gradient

Oikos, Volume 2022, Issue 11, November 2022., 2022
Widespread changes in temperature and precipitation patterns present plant species with new and combined stresses that affect their performance and distribution. Functional traits are indicators of plant resource use–acquisition strategies and thus they are commonly used to understand the geographic distributions of plant species and species' potential
