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 , ...

New arachnological (Araneae) records from Catalonia yield first records at regional, national and peninsular scale

Abstract

New arachnological (Araneae) records from Catalonia yield first records at regional, national and peninsular scale

We report 22 new arachnological records from Catalonia belonging to 22 species. The specimens were collected in various localities in the provinces of Barcelona and Girona between 2021 and 2024, using various sampling methods and covering a wide range of habitats. Six of the species correspond to the first records for the whole Iberian Peninsula, three for Spain, and 11 for Catalonia. Additionally, we report two species that have been found previously in Spain and Catalonia but without any given specific locality.
