Islanded Islands: Dual Isolation Drive Distinctive and Threatened Floras of Neotropical Maritime Inselbergs

Journal of Vegetation Science, Volume 36, Issue 3, May/June 2025.
ABSTRACT Questions Inselbergs, isolated rock outcrops, support unique plant communities. Maritime inselbergs (MIs) experience transient isolation due to maritime fluctuations, creating harsh survival conditions. This study is the first to investigate the plant communities' patterns on MIs, comparing them with those on continental inselbergs (CIs).

FITORREMEDIACIÓN DE UN SUELO CONTAMINADO CON PETRÓLEO EXTRA PESADO CON Megathyrsus maximus

Revista Internacional de Contaminación Ambiental, 2017
Soil contamination by petroleum is an environmental problem and phytoremediation has proved to be a promising method for treating such soils. However, selection of species for use in phytoremediation is a key factor for its successful application. The aim of this study was to investigate the phytoremediation potential of the grass Megathyrsus maximus

Effect of Fibrolytic Enzymes and Regrowth Ages on Fermentation Profile and Nutrient Composition of Mombasa Grass and Elephant Grass Silages

Grass and Forage Science, Volume 80, Issue 2, April-June 2025.
ABSTRACT Two experiments were carried out to evaluate whether the addition of cellulase and/or xylanase enzymes interacts with regrowth age (RA) in mombasa grass (Megathyrsus maximus) and elephant grass cv. BRS Capiaçu (Cenchrus purpureus) to alter nutritive composition and fermentation profile. Mombasa and elephant grass plots were mowed and harvested
