an updated checklist of the scorpion fauna of iran, as well as a brief history of taxonomic research on scorpions of iran is presented. the checklist is based on records of scorpion species whose presence has been confirmed in iran through field expeditions, examination of scorpion collections, literature review, and personal communications from researchers. the scorpion fauna consists of 51 sp...

Peromyscus ochraventer is a rodent species endemic of Mexico. In 1981, Robbins and Baker described its karyotype from one single female which presented 2n = 48 FN 60.

In order to test the feasibility of scorpion fluorescence as an indicator of gender and/or species identity, a comparison of the fluorescence spectra between genders across two sympatric species of scorpions (Vaejovis confusus Stahnke 1940 and Paruroctonus shulovi Williams 1970) was conducted. Each spectrum was represented in a simple multivariate analysis by its peak wavelength and width at 90...

Painful venoms are used to deter predators. Pain itself, however, can signal damage and thus serves an important adaptive function. Evolution to reduce general pain responses, although valuable for preying on venomous species, is rare, likely because it comes with the risk of reduced response to tissue damage. Bark scorpions capitalize on the protective pain pathway of predators by inflicting i...

This work succinctly describes the professional and scientific life of Dr. José R. Giglio, one of the most outstanding Brazilian researchers in the field of Toxinology. During his long and successful career, he has made major contributions, especially in elucidating the function, structure, and mechanisms of action of animal venom proteins (from snakes, scorpions and spiders) as well as the cha...

Scorpions are amongst the most ancient arthropods, as the oldest fossils were dated from the late silurian (Proscorpius osborni, 418 million years B.P.) [1]. Extant scorpions (with about 2,000 species spreading globally) are therefore 'living fossils', which retained all of the primitive features except that they are considerably smaller compared to their up to 1-meter long Brontoscorpio anglic...

purpose: scorpions in the middle eastern countries are known as the most widely spread poisonous creatures that cause casualties and death to human being and domestic animals. these creatures are distributed and well established in subtropical regions. among sixteen iranian islands in the persian gulf, kish island is the focus of important internal and foreign industrial and commercial activit...
