The Effect of Accuracy and Uncertainty in Test Performance on Optimal Early Detection Survey Budget Allocations

PhytoFrontiers, 2023
Early detection of pests at a low population prevalence is a key pillar of surveillance for plant health. A novel pest is expected to undergo exponential growth when it first occurs in a host population.

Integrating High throughput Sequencing into Survey Design Reveals Turnip Yellows Virus and Soybean Dwarf Virus in Pea (Pisum Sativum) in the United Kingdom

Viruses, 2021
There is only limited knowledge of the presence and incidence of viruses in peas within the United Kingdom, therefore high-throughput sequencing (HTS) in combination with a bulk sampling strategy and targeted testing was used to determine the virome in ...

Locating Sand

The Extractive Industries and Society, 2023
Sand extraction is quickly gaining attention both in the academic and policy communities. However, we lack grounded understandings of the multiple realities and impacts of sand extractions across the Global South. This special issue aims to provide a jumping-off point towards both empirically and conceptually sophisticated work on sand.
