Chemosensory response in stunted prairie rattlesnakes Crotalus viridis viridis
Rattlesnakes use chemical stimuli in ambush site selection and for relocation of envenomated prey through strike-induced chemosensory searching. Shifts in responsiveness to prey chemicals have been documented in many snakes, and often correlate with prey commonly taken as snakes increase in age and size as well as geographical locations of the species. For instance, neonate rattlesnakes that pr...
متن کاملHelminths of the Prairie Rattlesnake, Crotalus viridis viridis (Serpentes: Viperidae), from Western South Dakota
One hundred prairie rattlesnakes, Crotalus viridis viridis, from western South Dakota were examined for evidence of helminth parasites. Twenty-one percent were infected with 1 of 6 parasite species. The following species were recovered: Manodistomwn sp., Mesocestoides sp., Physaloptera sp., 2 different species of oligacanthorhynchid acanthocephala, and an unidentified species of acanthocephalan...
متن کاملEffect of bromocriptine on the larval skin of the green toad, Bufo viridis viridis leurenti.
In the premetamorphic larval green toad, B. viridis viridis, as in other anurans, the skin is made up of a fibrous dermis and an epidermis of stratified epithelium. The effects of bromocriptine, an antiprolactin drug, on the premetamorphic skin of B. viridis viridis was examined. Bromocriptine, dissolved in rearing water at four different concentrations, induced a number of changes in the skin ...
متن کاملBiokinetics of Cesium in Perna Viridis
The biokinetics of Cs in four compartments in the green-lipped mussel Perna viridis, namely, gill, viscera, adductor muscle, and foot, were studied. First-order linear differential equations were set up for these four compartments, and their solutions were used to fit the experimental data. The parameters governing the biokinetics, which depend on the elimination rate from each compartment and ...
متن کاملSetaria viridis: a model for C4 photosynthesis.
C(4) photosynthesis drives productivity in several major food crops and bioenergy grasses, including maize (Zea mays), sugarcane (Saccharum officinarum), sorghum (Sorghum bicolor), Miscanthus x giganteus, and switchgrass (Panicum virgatum). Gains in productivity associated with C(4) photosynthesis include improved water and nitrogen use efficiencies. Thus, engineering C(4) traits into C(3) crop...
