Effectiveness of integrated shrub management and restoration techniques for rehabilitating shrub‐encroached rangelands of South Africa

open access: yesGrassland Research, EarlyView.
Herbaceous plant recovery following shrub clearing and reseeding in the rangelands of Peddie, Eastern Cape of South Africa. CTL, control; CO, cutting only; CR, cutting and reseeding; UPO, uprooting only; UPR, uprooting and reseeding. Abstract Background Shrub encroachment (SE) drives rangeland degradation, threatening biodiversity and forage ...

Jointness in Bayesian variable selection with applications to growth regression [PDF]

open access: yes
The authors present a measure of jointness to explore dependence among regressors in the context of Bayesian model selection. The jointness measure they propose equals the posterior odds ratio between those models that include a set of variables and the ...

Climate change effects on biomass and greenhouse gas emissions are ameliorated by nontoxic endophytes in southeastern USA transition zone tall fescue pastures

open access: yesGrassland Research, EarlyView.
Tall fescue produces more biomass and less carbon dioxide from the soil when it contains its beneficial fungal endophyte. Increased temperatures projected with climate change reduce fescue biomass, while altered rainfall frequency does not. Altering rainfall frequency and increasing temperatures can reduce carbon dioxide emissions from soil.

On the effect of prior assumptions in Bayesian model averaging with applications to growth regression [PDF]

open access: yes
This paper examines the problem of variable selection in linear regression models. Bayesian model averaging has become an important tool in empirical settings with large numbers of potential regressors and relatively limited numbers of observations.

Exploring variations in potential carbon and nitrogen mineralization in managed grasslands among the diversity of soils in North Carolina

open access: yesGrassland Research, EarlyView.
Under steady–state conditions, potential nitrogen mineralization in soil under grasslands is closely tied to potential carbon mineralization. This study provides supporting evidence that field–specific nitrogen fertilizer recommendations could be indicated by using a simple and rapid analysis of soil–test biological activity.

Native grass breeding: Priority needs and strategic approaches

open access: yesGrassland Research, EarlyView.
The key needs and breeding strategies of native grass. Abstract Native grasses possess extensive ecological adaptability, such as cold, drought, and salt tolerance, and tolerance to poor soil conditions. They play a crucial role in ensuring food security and ecological security.
