Evaluating the suitability of reference sites to gauge the success of ecological restoration on arbuscular mycorrhizal fungal abundance and community composition

open access: yesRestoration Ecology, EarlyView.
Most ecological restorations aim to return degraded ecosystems to pre‐disturbance conditions, but community composition in restored ecosystems often differs from sites representative of a historical state and can more closely resemble semi‐natural or moderately disturbed ecosystems.

Prebiotic biostimulation for enhanced soil microbial activity and growth of diverse native grasses

open access: yesRestoration Ecology, EarlyView.
Given the urgency of addressing grassy ecosystem loss, there is a growing demand for cost‐effective, evidence‐based restoration and revegetation strategies for Poacaeae. Prebiotics applied to soils to promote microbial activity and diversity are widely used for grass crops in agriculture, but their efficacy in improving native grass establishment ...

Spatial Price Integration and Spillover Linkages Between Regional Grain Markets in Nigeria

open access: yesReview of Development Economics, EarlyView.
ABSTRACT This paper aims to characterize the spatial set‐up of Nigeria's grain market integration from January 2002 to December 2013 across 19 Nigerian regions. Using market price data of maize, sorghum, and millet, two hypotheses are tested: (i) the law of one price across market pairs, and (ii) the leader market hypothesis in any network of market ...

Traditional Versus Improved Varieties of Seed: Is There a Trade‐Off Between Productivity and Risk?

open access: yesReview of Development Economics, EarlyView.
ABSTRACT We examine how the choice of seed technology—between traditional and improved varieties—impacts crop revenue and the cost of risk in a setting characterized by high uncertainty. The methodological approach combines computation of crop revenue and cost of risk based on moment‐based approximation of a stochastic production function, with a ...

Effects of Mergers and Acquisitions on U.S. Agri‐Food Trade

open access: yesReview of International Economics, EarlyView.
ABSTRACT In recent years, mergers and acquisitions (M&As) in the agricultural and food sector have increased market power, and the resulting higher prices have eroded the competitiveness of U.S. firms in the world market. This study examines how mergers and acquisitions in the agri‐food industry contributed to a reduction in exports, an increase in ...
