The correct delineation of tick species is critical for efforts aimed at safeguarding One Health. Historically, the Asian turtle tick (Amblyomma geoemydae sensu lato) has been regarded as a geographically widespread species across much of Asia. However, based on morphological and phylogenomic data, the subtropical lineage (from Japan, Taiwan, and parts of China) of A. geoemydae is recognised as a new species: Amblyomma kappa sp. n., and all life stages are described. The tropical lineage of A. geoemydae sensu stricto is recharacterized and a differential diagnosis is provided to distinguish the two species. The ecology, host associations, and medical importance of A. kappa are also discussed.

Ensembles of Species Distribution Models (SDMs) represent the geographic ranges of pathogen vectors by combining alternative analytical approaches and merging information on vector occurrences with more extensive environmental data. Biased collection data impact SDMs, regardless of the target species, but no studies have compared the differences in the distributions predicted by the ensemble models when different sampling frameworks are used for the same species. We compared Ensemble SDMs for two important Ixodid tick vectors, and in mainland Florida, USA, when inputs were either convenience samples of ticks, or collections obtained using the standard protocols promulgated by the U.

As tick vector ranges expand and the number of tickborne disease cases rise, physicians, veterinarians, and the public are faced with diagnostic, treatment, and prevention challenges. Traditional methods of active surveillance (e.g.

The domesticated one-humped camel, Camelus dromedarius, is one of the most important animals in the Arabian Peninsula. For most of its life, this species is exposed to both intrinsic and extrinsic genotoxic factors that cause gross DNA alterations in many organisms. GST enzymes constitute an important supergene family involved in protection against the deleterious effects of oxidative stress and xenobiotics.
