Variable effects of wildlife and livestock on questing tick abundance across a topographical–climatic gradient

Ecosphere, Volume 16, Issue 2, February 2025.
Abstract Large‐bodied wild ungulates are declining worldwide, while domestic livestock continue to increase in abundance. Such changes in large herbivore communities should have strong effects on the control of ticks and tick‐borne disease as they can indirectly modify habitat and directly serve as final hosts for ticks' lifecycles.

Proposed Relationships Between Climate, Biological Soil Crusts, Human Health, and in Arid Ecosystems

GeoHealth, Volume 9, Issue 1, January 2025.
Abstract Biological soil crusts (or biocrust) are diminutive soil communities with ecological functions disproportionate to their size. These communities are composed of lichens, bryophytes, cyanobacteria, fungi, liverworts, and other microorganisms.

tRNA signatures reveal polyphyletic origins of streamlined SAR11 genomes among the alphaproteobacteria [PDF]

, 2013
Phylogenomic analyses are subject to bias from compositional convergence and noise from horizontal gene transfer (HGT). Compositional convergence is a likely cause of controversy regarding phylogeny of the SAR11 group of Alphaproteobacteria that have ...

Rickettsiosis Infections in Sarawak: Epidemiological Insights and Public Health Strategies

Canadian Journal of Infectious Diseases and Medical Microbiology, Volume 2025, Issue 1, 2025.
Rickettsiosis infections pose a significant public health concern in Sarawak, Malaysia. Despite their importance, these infections remain poorly recognised, under‐researched and inadequately documented within the context of the Sarawak region. This comprehensive evaluation seeks to address this knowledge gap by providing an in‐depth analysis of ...

Pet and Stray Dogs’ Contribution to Zoonotic Transmission Pathways: A Bibliometric Review

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Based on a large‐scale bibliometric dataset, domestic dogs (Canis lupus familiaris) emerge as the most frequently cited host species in the context of zoonoses, being mentioned in at least 10% of publications for nearly a quarter of the pathogens recognized as zoonotic to humans.

Diversity and structural‐functional insights of alpha‐solenoid proteins

Protein Science, Volume 33, Issue 11, November 2024.
Abstract Alpha‐solenoids are a significant and diverse subset of structured tandem repeat proteins (STRPs) that are important in various domains of life. This review examines their structural and functional diversity and highlights their role in critical cellular processes such as signaling, apoptosis, and transcriptional regulation.
