Firm turnover under asymmetric information: Tanzania's agro‐dealer sector

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract We study firm turnover (i.e., entry and exit) and its consumer implications in a market characterized by asymmetric information. Using a three‐round census of agro‐dealers in Tanzania's Morogoro Region, we document annual firm entry and exit rates of 33% and 17%, respectively.

Reproductive stages in lowbush blueberry (Vaccinium angustifolium) occur earlier with increasing temperature

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Climate change is altering the timing of many plant phenological events, yet most studies focus on flowering, with less attention given to later reproductive stages such as fruit development and ripening. Vaccinium angustifolium (lowbush blueberry) is an important perennial berry species that may be sensitive to these changes.

Performance Assessment and Lab‐Scale Economic Evaluation of Alkaline Extraction and Comparative Precipitation of Cyanobacterial Proteins

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Algal proteins from cyanobacteria serve as a natural source of biopolymers. The principal challenge manifests as nonoptimization of unit operations in downstream process accounting for higher costs. This study focuses on process assessment of unit‐operations for selecting suitable recovery strategies not only based on yield, but also considers

Bio‐Based Sodium Alginate Beads Reinforced With Microalgae (Limnospira platensis): Structure–Property Relationships and Controlled Release Potential

open access: yesJournal of Applied Polymer Science, EarlyView.
Development of sodium alginate beads doped with Limnospira platensis, designed for the gradual release of nutrients and bioactive molecules into soil. The biomaterial combines biodegradability, controlled‐release potential, and microalgal biomass valorization, contributing to reduced nutrient losses through leaching and the development of more ...

Integration of Nutrition and Organic Agriculture Framework in Managing Gastrointestinal Nematodes in Ruminants

open access: yesAnimal Research and One Health, EarlyView.
Gastrointestinal nematode infections damage the gastrointestinal epithelial tissues of ruminants, affecting nutrient utilization and overall production performance. This review outlines host‐gastrointestinal nematode interactions and discusses integrated control strategies, including nutritional supplementation, grazing management, vaccines, and ...

Pesticide Regulation Under NAFTA: Harmonization in Process? [PDF]

open access: yes
Different standards in pesticides and pest protection have often been used as trade barriers, whether real or manufactured. While harmonization is often touted as a means to limit the ability of domestic (protectionist) interests to use standards as a ...

Enhancing the Secretion Systems: Genetic Engineering of Super Bioagents for Effective Plant Disease Control

open access: yesBiotechnology and Bioengineering, EarlyView.
Genetic engineering (GE) overcomes BCA limits, enabling robust, scalable crop protection. “Super Bioagents” (SBs) use optimized SSs to enhance bioactive molecule delivery. Optimizing SSs enhance precise, sustainable effector deployment for stable disease suppression. SBs use microbiome‐informed design for scalable, next‐gen sustainable crop protection.
