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 ...

35th European Congress of Arachnology: Book of Abstracts

The 35th European Congress of Arachnology was held in Zadar, Croatia, from 31 August to 5 September 2025, bringing together researchers, taxonomists, ecologists, and systematists from across Europe and beyond to exchange current knowledge on arachnid biology. This congress continued the long-standing tradition of the European arachnological community by providing a dedicated forum for the presentation and discussion of advances in taxonomy, phylogenetics, biogeography, ecology, behavior, physiology, and conservation of arachnids, while also fostering collaboration between established experts and emerging scholars in the field.

The link provided grants access to the official Book of Abstracts from the congress, which compiles the scientific contributions presented throughout the meeting. This volume reflects the breadth and depth of contemporary arachnological research, encompassing oral presentations, poster sessions, and thematic symposia that collectively highlight methodological innovation, novel taxonomic insights, and integrative approaches to arachnid science. As such, it serves not only as a record of the scientific discourse that took place in Zadar, but also as a valuable reference for researchers seeking to stay informed about current trends and ongoing work within the discipline.

By making the Book of Abstracts publicly available, the organizers of the 35th European Congress of Arachnology have contributed meaningfully to the dissemination of knowledge and the continued advancement of arachnological research. The materials accessible through this link will be of particular interest to scientists, students, and citizen researchers who wish to engage with the latest findings presented at the congress and to situate their own work within the broader context of contemporary European and international arachnology.
