The jaw is a second-class lever in Pedetes capensis (Rodentia: Pedetidae)
The mammalian jaw is often modelled as a third-class lever for the purposes of biomechanical analyses, owing to the position of the resultant muscle force between the jaw joint and the teeth. However, it has been proposed that in some rodents the jaws operate as a second-class lever during distal molar bites, owing to the rostral position of the masticatory musculature. In particular, the infra...
متن کاملMolecular phylogeny of the springhare, Pedetes capensis, based on mitochondrial DNA sequences.
The phylogenetic position of the Pedetidae, represented by a single species Pedetes capensis, is controversial, reflecting in part the retention of both Hystricomorphous and Sciurognathous characteristics in this rodent. In an attempt to clarify the species evolutionary relationships, mtDNA gene sequences from 10 rodent species (representing seven families) were analyzed using phenetic, parsimo...
متن کاملKin Selection in the Annual Plant Impatiens Capensis
-Kin selection occurs when phenotypic variation in a character or set of characters is heritable, spatially structured, and has differential fitness effects on neighboring individuals. Spatially structured, heritable variation has been found for many characters of the annual plant Impatiens capensis (the first wo criteria). By manipulating plant growth by apical removal, I show that Impatiens f...
متن کاملThe indumentum of vegetative and reproductive parts of annual Silene L. species (Caryophyllaceae) in Iran
Large and diverse genera, such as Silene need more reliable morphological traits for the credible identification and delimitation of the species. Despite the fact that the type of indumentum among the species of Silene had been addressed in most available revisions, monographs and floristic studies, the trichome-based features and their adaptational importance have not been investigated explici...
متن کاملPattern of Sex Steroid Concentrations in Relation to the Annual Reproductive Cycle of Wild and Captive Black Rockfish
—Gonadal development and plasma steroid hormone concentrations of wild (N1⁄4 73) and captive (N1⁄465) black rockfish Sebastes melanops were examined over 1 year. Seasonal variation was observed in the concentrations of testosterone and estradiol in the plasma of wild female black rockfish, the highest concentrations of each occurring in October. Male black rockfish exhibited the highest testost...
