Sympatry Increases Predation Risk for an Endangered Ungulate

Ecology and Evolution, Volume 16, Issue 8, August 2026.
We characterized predation risk for Peninsular bighorn sheep and southern mule deer across their ranges to understand how topography, habitat, forage, and prey habitat suitability affect where pumas are likely to predate both species. The presence of the second ungulate species increased predation risk for both species but had the greatest effect on ...

REDUCTION OF ZEBRA CHIP INFECTION SYMPTOMS IN POTATO

Tropical and Subtropical Agroecosystems
Background: There have been few studies on the long-term effects of hydrogen peroxide and dehydroascorbate (H2O2 and DHA) on biotic stress, especially in potato plants infected with Candidatus Liberibacter solanacearum (Lso) that cause the Zebra chip ...

Global gene expression in two potato cultivars in response to ‘Candidatus Liberibacter solanacearum’ infection

BMC Genomics, 2017
Background Transcriptomic analyses were performed to compare the molecular responses of two potato varieties previously shown to differ in the severity of disease symptoms due to infection by “Candidatus Liberibacter solanacearum” (Lso), the causative ...

Mechanisms of Resistance, Insights From Case Reports, and Future Prospects in Mycobacteriophage Therapy

Journal of the Royal Society of New Zealand, Volume 56, Issue 4, August 2026.
Evolution of drug‐resistant mycobacterial infections warrants renewed efforts in identifying more efficient preventive and control strategies as well as alternative treatment options. Interest in phage therapy is regaining significant traction, especially in cases of failed conventional therapy.

Bactericera cockerelli Picorna-like Virus and Three New Viruses Found Circulating in Populations of Potato/Tomato Psyllids (Bactericera cockerelli)

Viruses
An investigation of viruses circulating in populations of field and laboratory potato/tomato psyllids (Bactericera cockerelli) was conducted using high-throughput sequencing (HTS) technology and conventional RT-PCR. Three new viruses were discovered: one

Characterization of the Tolerance against Zebra Chip Disease in Tubers of Advanced Potato Lines from Mexico [PDF]

American Journal of Potato Research, 2017
Potato zebra chip disease (ZC), a threat to potato production in the USA, Mexico, New Zealand, and Central America, is associated with the bacterium “Candidatus Liberibacter solanacearum” (Cls) that is vectored by the potato psyllid (Bactericera cockerelli Sulc.).

Long‐term reduction of invasive killer shrimp (Dikerogammarus villosus) density following removal of zebra mussel (Dreissena polymorpha) shells and coarse substrate on UK lake beds

Ecological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
Working with Citizen Scientists, researchers tested manual removal of coarse cobbles and zebra mussel shells from fine‐sediment lake beds to reduce invasive killer shrimp densities. Killer shrimp use these features for habitat, and after clearing them from 3 × 3 m sections of lakebed, killer shrimp densities were reduced by over 90% in these sections ...

Improved Detection and Sequencing of Rickettsia spp. DNA in South African Wildlife

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Nested gltA PCR detected Rickettsia spp. DNA in 44% of South African wildlife samples previously negative by RLB, revealing spotted fever, typhus and transitional group lineages, novel host records, co‐infection and multi‐organ dissemination in impala, highlighting complex wildlife involvement and zoonotic risk within a One Health framework.

Genomic sequence of 'Candidatus Liberibacter solanacearum' haplotype C and its comparison with haplotype A and B genomes.

PLoS ONE, 2017
Haplotypes A and B of 'Candidatus Liberibacter solanacearum' (CLso) are associated with diseases of solanaceous plants, especially Zebra chip disease of potato, and haplotypes C, D and E are associated with symptoms on apiaceous plants.

Comparative Phylogenomic Analysis Reveals Evolutionary Genomic Changes and Novel Toxin Families in Endophytic Liberibacter Pathogens

Microbiology Spectrum, 2021
Liberibacter pathogens are the causative agents of several severe crop diseases worldwide, including citrus Huanglongbing and potato zebra chip. These bacteria are endophytic and nonculturable, which makes experimental approaches challenging and ...
