Medición de calidad en semillas de Andropogon gayanus

Revista Brasileira de Sementes, 1986
Andropogon gayanus es una nueva especie de gramínea para América Latina, liberada formalmente en cinco países. Actualmente, fuentes de semilla comercial se están incrementando y comercializando lo cual exige el conocimiento y la disponibilidad de medidas de calidad.

Diverse soil seedbanks are resilient to reintroducing low‐intensity fire in a subtropical grassy woodland

Journal of Applied Ecology, Volume 63, Issue 5, May 2026.
Seedbanks in this grassy woodland provide a rich biodiversity reservoir which persisted after low‐intensity fire. Patterns of species replacement suggest that activities which diminish above‐ground plant diversity (such as overgrazing or conversion to forest) will impact biodiversity at larger spatial scales, while soil seedbanks are likely more robust

Harvesting stages and additives affect fermentation characteristics, nutritional value, and animal preference for silages from Andropogon ( Andropogon gayanus ) grass

Cogent Food & Agriculture, 2023
Despite its rapid growth and adaptability, Andropogon (Andropogon gayanus 12,465) was not preserved to address the severe feed deficit in the prolonged dry season in Ethiopia. Determining how the harvesting stage and additives (AD) affect the silage quality, animal preference, and digestibility of Andropogon was the objective of the current study ...

The Effectiveness of Prescribed Fire for Native Grassland Restoration and Exotic Weed Control Differs Between Soil Types

Austral Ecology, Volume 51, Issue 4, April 2026.
ABSTRACT The presence of invasive species often makes the use of prescribed fire for native grassland restoration challenging, as fire could also facilitate exotic plant invasion. The outcome of fire treatment may depend on variation in soil environments.

Invasive Andropogon gayanus (gamba grass) is an ecosystem transformer of nitrogen relations in Australian savanna [PDF]

Ecological Applications, 2009
Invasion by the African grass Andropogon gayanus is drastically altering the understory structure of oligotrophic savannas in tropical Australia. We compared nitrogen (N) relations and phenology of A. gayanus and native grasses to examine the impact of invasion on N cycling and to determine possible reasons for invasiveness of A. gayanus.

Detecting and attributing climate change effects on vegetation: Australia as a test case

PLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 461-485, March 2026.
Climate change is contributing to vegetation changes that threaten life support systems. Yet, inherent climatic variability and past and present human actions—such as clearing, burning and grazing regimes—also alter vegetation and complicate understanding of vegetation change. Australian ecosystems exemplify such complexity.

Permanence Risks to Biodiversity and Nature‐Based Carbon Offsets

Conservation Letters, Volume 19, Issue 2, March/April 2026.
ABSTRACT Biodiversity and nature‐based carbon offsets are central to strategies addressing biodiversity loss and climate change. Their credibility depends on permanence—the expectation that biodiversity gains or sequestered carbon persist at least as long as the impacts they compensate for, or in perpetuity.

Screening of Grasses’ Chemical Composition Variability and Methane Emissions in Colombian Livestock Ecoregions Using Digital Bromatology

International Journal of Agronomy, Volume 2026, Issue 1, 2026.
Grasses’ nutritional characteristics and management are fundamental for grazing cattle to guarantee sustainability in tropical conditions. This study aims to analyze the pastures’ chemical composition variability and methane emissions in different Colombian ecoregions and productive activities using digital bromatology data.
