Whether Cannabis is polytypic
(one species with many kinds) or polyspecific (more one than one species) became a polarized debate in court cases.
species revisited: genetic differentiation and molecular phylogenetics of the tiger salamander Ambystoma tigrinum (Amphibia: caudata) complex.
The south-eastern house mouse Mus musculus castaneus (Rodentia: Muridae) is a polytypic
The hamster is a polytypic
species and the range covered in our study is believed to be occupied by seven distinct subspecies (Berdyugin & Bolshakov 1998).
The barred tiger salamander [Ambystoma mavortium (Baird, 1850)] is a polytypic
species with multiple distinct morphologies, making it popular for studies of phenotypic plasticity and evolution.
A new subspecies of the polytypic
lizard Sceloporus undulatus (Sauria: Iguanidae) from northern Mexico.
Specific topics include the effect of wetting-drying cycles on the behavior of hydrophilic additives in mineral wool, a preliminary study of basalt fibers as a sustainable reinforcement for cement-based mortars, the ultrasonic monitoring of a bending test of glass-fiber-reinforced cement, press and injection hybrid molding of thermoplastics reinforced with glass fiber, polytypic
heterjunctions for wide bandgap semiconductor materials, and the simultaneous effect of surface roughness and passivity on the corrosion resistance of metals.
B cells are often numerous (10%-60% of the infiltrate), (10,17,20-23) and intermixed plasma cells are typically polytypic
Phacellodomus ruffrons, considered a single, polytypic
species, is the most widespread species of Phacellodomus in South America, covering at least 19 ecoregions, such as La Costa xeric shrublands, Cerrado and Serra do Mar coastal rainforest.
