Emerging potato pathogens affecting food security in southern Africa: Recent research

South African Journal of Science, 2020
Potato is a staple crop that contributes to food security and poverty alleviation in developing nations. Despite this, yields in developing nations are often unsustainably low, due to various biotic and abiotic factors that negatively affect production ...

Eco‐Evo‐Hydraulics: Integrating Fish Evolution Into Ecohydraulics for Conservation

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Riverine fish conservation in eco‐hydraulics is often based on restoring or regulating river habitat to a semi‐natural state. For example, ecohydraulic projects support fish populations by increasing river connectivity through fishways, and by maintaining or restoring natural flow variance to enhance habitat quality and availability.

Significance and Epidemiological Aspects of Late-Season Infections in the Management of Potato Zebra Chip [PDF]

Phytopathology®, 2015
Zebra chip (ZC) of potato is putatively caused by the fastidious, phloem-limited bacterium ‘Candidatus Liberibacter solanacearum’ (Lso), which is transmitted by the potato psyllid (Bactericera cockerelli). The disease, which significantly impacts both crop yield and quality, was first identified in the United States from south Texas in 2000.

Empowering Rural Communities to Measure Walkability: Co‐Development of a Digital Tool

Health Expectations, Volume 29, Issue 2, April 2026.
ABSTRACT Background Local neighbourhood environments are important for shaping walkability, but few instruments exist to assess walkability in rural areas. Furthermore, there are no existing tools that have been designed with and for communities to collect local data on walkability, which has the potential to empower communities with ownership and ...

First Report of Zebra Chip and ‘Candidatus Liberibacter solanacearum’ on Potatoes in Nicaragua

Plant Disease, 2013
In September 2011, potato (Solanum tuberosum) tubers grown in Nicaragua outside of Estelí and Jinotega were observed with internal discoloration suggestive of zebra chip (ZC); and the plants showed foliar symptoms of chlorosis, leaf scorching, wilting, vascular discoloration, swollen nodes, twisted stems, and aerial tubers (3).

Bridging the gap: improving methodologies for future avian microbiome research

Journal of Avian Biology, Volume 2026, Issue 2, March 2026.
Recent advances in the field of wild avian microbiome research have significantly deepened our understanding of the eco‐evolutionary dynamics of bird–microbe interactions. Consequently, the field is now approaching a pivotal moment in uncovering the ultimate factors shaping avian microbiome structure, especially in relation to birds' ecological ...

Bactericera cockerelli (Sulc), a potential threat to China's potato industry

Journal of Integrative Agriculture, 2020
The potato psyllid Bactericera cockerelli (Hemiptera: Triozidae) has recently emerged as a serious pest of potatoes and other solanaceous crops. It causes direct feeding damage and also vectors Candidatus Liberibacter solanaceaerum (Lso), a pathogen that
