Presence and abundance of airborne Botryosphaeriaceae conidia are governed by temperature and season in the Okanagan Valley, Canada

open access: yesPest Management Science, EarlyView.
Presence and abundance of Botryosphaeria dieback inoculum were determined using spore trapping and droplet digital polymerase chain reaction in British Columbia, Canada. Highest inoculum was recorded in spring (April–June) and again in summer (July–September). These results suggest early pruning in December–January can mitigate pruning wound infections.

Effects of timed LED regimes on tomato plant traits, performance of two‐spotted spider mites, and predatory mites (Phytoseiulus persimilis)

open access: yesPest Management Science, Volume 81, Issue 4, Page 2300-2311, April 2025.
Light‐emitting diode (LED)‐based treatments for enhancing crop production and pest management have primarily focused on continuous treatments. This study, using Tetranychus urticae and Phytoseiulus persimilis, demonstrates that the timing of LED supplementation is crucial for designing integrated pest management strategies that improve both plant ...

A narrative review of count data models

open access: yesJournal of Interventional Epidemiology and Public Health
Introduction: Count data represent the frequency of event occurrences; therefore, they are inherently discrete and non-negative. Modelling such data presents considerable challenges when excessive zeros exist or when variability exceeds expected levels ...

ESTIMATION ISSUES IN SINGLE COMMODITY GRAVITY TRADE MODELS [PDF]

open access: yes
Recently gravity trade models are applied to disaggregated trade data. Here many zeros are characteristic. In the presence of excess zeros usual Poisson Pseudo Maximum Likelihood (PPML) is still consistent, the variance covariance matrix however is ...

Discovery and Fine‐Scale Mapping of Hadal Xenophyophore Habitat in the Nova Canton Trough, Central Pacific Ocean

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Discovery and fine‐scale mapping of a hadal xenophyophore field: submersible video transects and photogrammetry enable semi‐automated delineation of xenophyophores, revealing their abundance, spatial organisation, structural complexity and contribution to habitat heterogeneity at ~8000 m depth.

Distributed Sequential Zero-Inflated Poisson Regression

open access: yes, 2021
The zero-inflated Poisson regression model is a generalized linear model (GLM) for non-negative count variables with an excessive number of zeros. This letter proposes its low-cost distributed sequential inference from streaming data in networks with ...

Temporal grammars of novelty: How carbon removal entrepreneurs frame new technologies

open access: yesStrategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary This paper assesses the ways in which carbon dioxide removal ventures frame their work. Drawing on George Herbert Mead's philosophy of the present, it conceptualizes temporal grammars of novelty as a framing strategy that involves connecting two points in time, namely present and future, to elaborate novelty.
