Comparison of the in vitro neuromuscular activity of venom from three Australian snakes (Hoplocephalus stephensi, Austrelaps superbus and Notechis scutatus): efficacy of tiger snake antivenom.
1. Tiger snake antivenom, raised against Notechis scutatus venom, is indicated not only for the treatment of envenomation by this snake, but also that of the copperhead (Austrelaps superbus) and Stephen's banded snake (Hoplocephalus stephensi). The present study compared the neuromuscular pharmacology of venom from these snakes and the in vitro efficacy of tiger snake antivenom. 2. In chick biv...
متن کاملGenetic Assimilation and the Postcolonization Erosion of Phenotypic Plasticity in Island Tiger Snakes
In 1942, C.H. Waddington [1] suggested that colonizing populations could initially succeed by flexibly altering their characteristics (phenotypic plasticity; [2-4]) in fitness-inducing traits, but selective forces would rapidly eliminate that plasticity to result in a canalized trait [1, 5, 6]. Waddington termed this process "genetic assimilation"[1, 7]. Despite the potential importance of gene...
متن کاملSwimming and pregnancy in Tiger snakes, Notechis scutatus
Reduced locomotor ability may increase susceptibility to predation and hence may represent a proximate mechanism by which “costs” of reproduction are expressed (Shine, 1980). In squamate reptiles, many examples of such effects have been documented, where non-gravid females and/or males showed higher survival rates than gravid females (Shine, 1980; Andren, 1982, 1985; Madsen, 1987). For instance...
متن کاملIsolation and amino acid sequence of a neurotoxic phospholipase A from the venom of the Australian tiger snake Notechis scutatus scutatus.
The complete amino acid sequence of notechis 5, a neurotoxic phospholipase A from the venom of Notechis scutatus scutatus (Australian tiger snake), has been elucidated. The main fragmentation of the 119-residue peptide chain was accomplished by digesting the reduced and S-carboxymethylated derivative of the protein with a staphylococcal protease specific for glutamoyl bonds. Tryptic peptides we...
متن کاملInfluences on venom yield in Australian tigersnakes (Notechis scutatus) and brownsnakes (Pseudonaja textilis: Elapidae, Serpentes).
The rates at which venomous animals produce venoms are of obvious biological and medical importance, but factors influencing those rates remain poorly understood. We gathered data on venom yield (wet mass of venom) and percentage solids (dry mass of the venom divided by wet mass) for 53 eastern brownsnakes (Pseudonaja textilis) and 36 mainland tigersnakes (Notechis scutatus) over a 4-year perio...
