Spatial context allows the evolution of the control of nitrification by plants

Journal of Ecology, Volume 113, Issue 11, Page 3478-3490, November 2025.
Using a theoretical approach, we show that assuming that the effects of the control of nitrification are spatially restricted to the rhizosphere, the control of nitrification is likely to be selected in perennial plants and ecosystems in which nitrate losses are greater than ammonium losses. The selected strategy optimizes biomass production.

Productivity of herbaceous phytomass under different managements in the semi-arid region of Ceará= Produtividade de fitomassa herbácea em diferentes manejos no semiárido cearense

Agro@mbiente On-line, 2016
The aim of this study was to evaluate the productivity of dry phytomass in the herbaceous layer, under different managements in the Caatinga biome. Three watersheds were evaluated, a plot of caatinga preserved for 35 years (CC), another under thinning ...

What Does the Triple Isotopic Composition of Oxygen in Precipitation, Groundwater, Soil Water, Plant Water, and Phytoliths Reveal About Current and Past Hydrological Cycles?

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 10, October 2025.
Abstract Quantitative data are needed to constrain the feedback loops between vegetation and hydroclimate. In this study, the amplitudes of variations in the triple oxygen isotope composition of water at the soil‐plant‐atmosphere interface are measured in savanna and dry forest contexts in West Africa (Benin and Senegal). Comparison of in situ data and

Caracterización de fincas adoptadoras del pasto Andropogon gayanus en el departamento del Cesar, Colombia Caracterización de fincas adoptadoras del pasto Andropogon gayanus en el departamento del Cesar, Colombia

Acta Agronómica, 1987
La razón expuesta por ganaderos para adoptar el pasto A. gayanus es la de poseer una especie que les provea forraje en la época seca. Quienes mayor éxito han obtenido, hasta el momento, son los adoptadores de suelos arenosos o de sabana en la parte ...

Resource-use efficiency explains grassy weed invasion in a low-resource savanna in north Australia

Frontiers in Plant Science, 2015
Comparative studies of plant resource use and ecophysiological traits of invasive and native resident plant species can elucidate mechanisms of invasion success and ecosystem impacts.

Functional Plant Species Traits That Shape Canopy Light Interception and Agronomic Performance of Perennial Forage Grasses Cultivated in Monoculture and Association

Grass and Forage Science, Volume 80, Issue 3, July-September 2025.
ABSTRACT Functional traits of plants control a series of agronomic and ecological responses that are related to plant productivity. The botanical proportion and productive performance of forage grass species associations are underpinned by shifts in plant traits and associated resource (especially light) partitioning.

Impact of land management on herbaceous vegetation diversity and forage provision in the Great Green Wall in Burkina Faso

Grassland Research, Volume 4, Issue 2, Page 105-120, June 2025.
According to the disturbance gradient, the species richness of herbaceous vegetation increased from fenced (less disturbed) to fallow (most disturbed). The pastoral value and biomass production of grazing land were higher in protected areas (fenced land) than in unprotected areas (community forests and fallow land), suggesting that conservation ...
