Risk management externalities in agrifood supply chains

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Firms may under‐ or over‐invest in risk management from the social planner's perspective, resulting in a negative externality on other economic agents in the supply chain. The externality of risk management is particularly relevant for agrifood supply chains, which frequently experience disruptions and play a primary role in preventing major ...

Novel genes for insect resistance in transgenic plants [PDF]

open access: yes, 1995
From a cDNA library of potato tuber, cDNAs for the potato carboxypeptidase inhibitors were isolated and characterised by DNA sequencing. One full length clone of each type was used to make plant expression constructs, and these constructs used to ...

High‐elevation endemic plants predicted to lose habitat from changing climate in Washington State

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise High‐elevation plants face unique challenges from potential climate change impacts that will likely require upslope migration into increasingly smaller suitable habitat. This situation is particularly acute for endemic species that by definition occupy small geographic ranges.

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.

Migrations and Multiplications of Bursaphelenchus xylophilus and B. mucronatus in Pinus thumbergii in Relation to Their Pathogenicity

open access: yesThe Plant Pathology Journal, 2013
To evaluate the mechanisms of pathogenicity and non-pathogenicity of Bursaphelenchus xylophilus and B. mucronatus isolated in South Korea, we used 4-year-old P. thunbergii seedlings and 20-cm long one-year-old stem cuttings of 5-year-old Pinus thunbergii,

Affected Persons in Laboratory Exposures to Human Pathogens and Toxins in Canada, 2016–2024: A Sector‐Specific Analysis

open access: yesAmerican Journal of Industrial Medicine, EarlyView.
ABSTRACT Background Exposures to human pathogens and toxins in licensed facilities in Canada have been monitored by a federal surveillance system since 2015, yet the affected persons (APs) in these incidents remain uncharacterized. This study comprehensively describes APs, highlighting sector‐specific patterns and trends over time.

Ant Diversity of the Xisha Islands: Community Structure, Exotic Species Colonization, and Ecological Functions in a Tropical Coral Archipelago

open access: yesBiological Diversity, EarlyView.
The first inventory of ants from the Xisha Islands of the South China Sea was compiled, revealing 21 species: 70% native and 30% exotic. Anthropogenic disturbance primarily drove exotic colonization, whereas island area showed weak positive effects on species richness. Most ants were omnivorous, with key mutualistic and seed‐dispersal roles.
