Envenomation by these snakes commonly causes hematotoxic effects, including platelet dysfunction and coagulation disturbances. Although antivenom remains the mainstay of treatment, species-specific antivenoms are not available for several regional pit viper species. This study evaluated the hematotoxic activities of selected Southeast Asian pit viper venoms and the cross-neutralizing capacity of commercially available antivenoms.  Methods : Venoms from five medically important pit viper species— Calloselasma rhodostoma ,  Trimeresurus albolabris ,  T. hageni ,  T. purpureomaculatus , ...

In Memoriam: Gérard Dupré (1947–2026) — A Life Devoted to the Study of Scorpions

The passing of Gérard Dupré (1947–2026) is a deeply felt loss for those of us who share an interest in the study of scorpions and other arachnids. Throughout his life, he dedicated himself to documenting and preserving arachnological knowledge, contributing valuable work on scorpion taxonomy, distribution, and bibliography. His careful attention to the literature helped bring clarity and organization to a field whose history spans centuries and many languages.

Gérard was also closely associated with the journal Arachnides, which became an important outlet for sharing research, faunistic records, and historical notes within the arachnological community. Through this work, he helped ensure that observations and studies—large and small—were preserved and made accessible to others with similar scientific interests.

Beyond his scholarly contributions, Gérard was a humble and generous individual who engaged warmly with colleagues and enthusiasts alike. I had the privilege of communicating with him regularly over the years. Our conversations often revolved around arachnology and the literature surrounding scorpions, subjects he approached with genuine enthusiasm and deep knowledge. Our last exchange took place on the 3rd of March of this year, a correspondence I now look back on with particular appreciation.

I also remember him as one of the very first followers of my blog, Arácnido Taxonomy. His early support meant a great deal to me, and it reflected the kind of person he was—encouraging, attentive, and quietly supportive of the work of others in the field.

With his passing, the arachnological community loses not only a dedicated scholar but also a thoughtful and kind presence. His work will continue to be consulted and valued, and he will be remembered with respect and gratitude by those who knew him and by many others who benefited from his efforts.

Rest in peace, my friend.
