Highly expressed genes are preferentially co-opted for C4 photosynthesis [PDF]

, 2017
Novel adaptations are generally assembled by co-opting pre-existing genetic components, but the factors dictating the suitability of genes for new functions remain poorly known.

Ferramentas moleculares no melhoramento genético de Megathyrsus maximus para o semiárido: uma revisão

Research, Society and Development, 2020
A necessidade de ter alimentos à disposição do rebanho, ao longo do ano, gera esforços para desenvolver métodos e técnicas para adaptar forrageiras tropicais a regiões com déficit hídrico. Nessa perspectiva, o objetivo desta investigação foi realizar uma revisão de literatura sobre gramíneas forrageiras da espécie Megathyrsus maximus e ferramentas ...

Here, There and Everywhere: Widespread Non‐Native Plants in the World's Urban Ecosystems

Global Ecology and Biogeography, Volume 34, Issue 11, November 2025.
ABSTRACT Aim To (a) produce a list of the most widespread naturalised non‐native plant species across cities of the world; (b) explore whether cities on different continents are invaded by the same group of widespread naturalised species; and (c) elucidate the origins of the most widespread naturalised urban species. Location Global.

Soil seed banks in three restored wildlife corridors; implications for linear habitats in tropical environments

Restoration Ecology, Volume 33, Issue 8, November 2025.
Restoring habitat corridors between fragments and continuous forests can potentially counter the effects of isolation, especially in tropical forests where species sensitivity to fragmentation is high. The ability of restored linear habitats to absorb natural disturbance in inimical surroundings potentially reflects resilience, an important aim of ...

The role of competition in moderating plant–soil feedback for restoring ecosystems invaded by Brazilian peppertree (Schinus terebinthifolia Raddi)

Restoration Ecology, Volume 33, Issue 8, November 2025.
Abstract Introduction Ecosystem restoration requires the management of invasive plants due to the harmful effects they have on both above‐ and belowground ecosystem processes. Belowground soil modifications by invasive plants, particularly those driven by plant–soil feedbacks (PSFs), are thought to significantly influence an invader's success by ...

Sustitución del pasto Megathyrsus maximus por guineo cuadrado y urea en mezclas ensiladas

Agronomía Mesoamericana, 2019
Introducción. Los pastos tropicales poseen mayor contenido de fibra en proporción con otros nutrientes, esto limita el consumo de materia seca por parte de los rumiantes. El uso de aditivos en el ensilaje permite optimizar el contenido nutricional en los forrajes que pueden conservarse para utilizarlos en momentos de menor disponibilidad forrajera ...
