Die Sandrasselotter aus Westafrika: Echis carinatus ocellatus subsp. nov. (Serpentes, Viperidae)

Postprandial thermogenesis in Bothrops moojeni (Serpentes: Viperidae)

Snakes that can ingest prey that are proportionally large have high metabolic rates during digestion. This great increase in metabolic rate (specific dynamic action – SDA) may create a significant augment in the animal’s body temperature. The present study investigated postprandial thermogenesis in Bothrops moojeni. Briefly, two groups of snakes were fed meals equivalent to 17 ± 3% and 32 ± 5% ...

A Fatal Case of Snake-Bite (? Echis Carinatus) during Pregnancy

Enzymatic Analysis of Iranian Echis carinatus Venom Using Zymography

Snakebite is a common problem especially in tropical areas all over the world including Iran. Echis carinatus as one of the most dangerous Iranian snakes is spreading in this country excluding central and northwest provinces. In this study gelatinase and fibrinogenolytic properties as two disintegrating matrix metalloproteinase enzymes were evaluated by a strong clear halo between 56-72 kDa in ...

Bayesian mixed models and the phylogeny of pitvipers (Viperidae: Serpentes).

The subfamily Crotalinae (pitvipers) contains over 190 species of venomous snakes distributed in both the Old and New World. We incorporated an extensive sampling of taxa (including 28 of 29 genera), and sequences of four mitochondrial gene fragments (2.3kb) per individual, to estimate the phylogeny of pitvipers based on maximum parsimony and Bayesian phylogenetic methods. Our Bayesian analyses...

Reproductive Biology of Agkistrodon Piscivorus Lacépède (squamata, Serpentes, Viperidae, Crotalinae)

Aspects of the reproductive biology of male and female Agkistrodon piscivorus are described using histological techniques, reviewed, and compared with historical data on A. piscivorus. These include anatomical description at the macro and microscopic levels, and correlation of the male and female urogenital cycles to the reproductive life history of A. piscivorus. New anatomical descriptions an...
