Preharvest application of antagonistic yeasts for the control of fungal pathogens in organic peach and plum orchards

Journal of the Science of Food and Agriculture, Volume 106, Issue 10, Page 5881-5889, 15 August 2026.
Abstract BACKGROUND The control of fungal diseases in organic fruit production remains a major challenge due to the limited availability of authorized phytosanitary tools. This study evaluates the efficacy of two antagonistic yeasts – Metschnikowia pulcherrima L672 and Hanseniaspora uvarum L793 – in organic peach ( Prunus persica ) and plum ( Prunus ...

Citizen‐Science Camera Trap Data Reveal Large‐Scale Activity Patterns of the Bobcat (Lynx rufus) Across Mexican Ecosystems

Ecology and Evolution, Volume 16, Issue 7, July 2026.
We evaluated whether citizen science–derived camera‐trap records can be used to characterize large‐scale activity patterns of a widely distributed mesocarnivore across heterogeneous landscapes. Using 821 independent iNaturalist records, we quantified activity across six major vegetation types in Mexico with kernel density estimation, circular ...
