Qualitative and Quantitative Proteomic Analysis of Venoms from Mexican Rattlesnakes

  Qualitative and Quantitative Proteomic Analysis of Venoms from Mexican Rattlesnakes Abstract Despite the vast biodiversity of Mexican vipers, venom of endemic species has been barely studied. Here we analyzed the venom composition of three endemic species of rattlesnakes: Crotalus aquilus , C. triseriatus , and C. ravus . We used quantitative chromato-mass-spectrometry and compared venoms with C. molossus , a species commonly found in North America, in a comparative and phylogenetic framework. In total, we identified 165 proteins grouped in 19 main protein families, consistent with previous reports for viperid venoms. In C. aquilus and C. triseriatus , the most predominant protein-family type was Serine Proteases, and in C. triseriatus and C. molossus it was Snake Venom Metalloproteases. The Label-free quantification revealed a high proportion of Snake Venom Metalloproteases in C. aquilus , C. triseriatus , and C. molossus , reaching 28–47% of the total venom. In contrast, in ...

Additions to the list of scorpions (Arachnida: Scorpiones) intercepted as stowaways in the United Kingdom

Abstract
Sherwood & Armas (2023) provided a comprehensive and up to-date list of scorpions detected as stowaways in the United Kingdom. Since that work, the senior author has received further enquiries which contribute a number of new records for the literature. Furthermore, it came to our attention through correspondence with colleagues that we ought to examine the press media for examples of further cases, although these of course are not part of the scientific literature and have not passed peer-review. Nonetheless, we have evaluated these records and found a number with photographs and other information which allow us to provide a family or genus-level identification, at the very least, and in some cases even a species-level identification.
