background: scorpions are known as the most widespread poisonous creatures that cause casualties and death to human. they are distributed in tropical and subtropical areas. among the sixteen iranian island in the persian gulf, qeshm island is the biggest and is located in the focus of the important internal and international commercial marinelines. furthermore, thousands of tourists also visit ...

Scorpion venom is the richest source of peptide toxins with high levels of specific interactions with different ion-channel membrane proteins. The present study involved the amplification and sequencing of a 310-bp cDNA fragment encoding a beta-like neurotoxin active on sodium ion-channel from the venom glands of scorpion Androctonus crassicauda belonging to the Buthidae family using r...

Evaluating the effect of parasites on population size is essential for designing management and conservation plans of wild animal populations. Although knowledge in this area is scarce in cetaceans, current evidence suggests that species of the nematode genus Crassicauda may play an important regulatory role in some populations. In the present study, a semiparametric regression technique was ap...

Introduction: Considering wide distribution of scorpions in various parts of the country and their importance in biological and medical Sciences, the current study was performed during 2005 to 2006 in order to determine scorpions species in Kerman/Iran. Method: In this descriptive research, 13 cities in Kerman province were investigated. All collected scorpion specimens in %75 ethyl alcohol wer...

Parasitism was advanced by Delyamure (1955) as a major factor in the natural mortality of cetaceans, and infestation by helminths was implicated strongly as the cause of death in some stranded common dolphins (Delphinus delphis) (Ridgway and Dailey 1972). Severe and irreversible lesions of the skull of dolphins (Stenella spp.) caused by a nematode (Crassicauda sp.) were more prevalent among you...
