Embryogenesis and tadpole description of Hyperolius castaneus Ahl, 1931 and H. jackie Dehling, 2012 (Anura, Hyperoliidae) from montane bog pools
Tadpoles of Hyperolius castaneus and Hyperolius jackie were found in the Nyungwe National Park in Rwanda and adjacent areas. Tadpoles of both species were identified by DNA-barcoding. At the shore of a bog pool three clutches of Hyperolius castaneus of apparently different age, all laid on moss pads (Polytrichum commune, Isotachis aubertii) or grass tussocks (Andropogon shirensis) 2-5 cm above ...
متن کاملHyaluronidase from Tadpole Tissue.
The connective tissues of the tadpole undergo extensive remodeling during metamorphosis. In the resorbing tail fins of bullfrog tadpoles, there is a rapid degradation of collagen in the basement lamella coupled with dehydration and loss of the gelatinous core of the fin (1,2). The layers of the dense collagenous basement lamella are loosened, frayed, and invaded by mesenchymal cells.1 A collage...
متن کاملTadpole-like artificial micromotor.
We describe a polymer-based artificial tadpole-like micromotor, which is fabricated through the electrospinning technique. By incorporating functional materials onto its surface or within its body, the resulting tadpole-like micromotor can not only move autonomously in an aqueous solution with a flexible tail, but also exhibit thermo- and magnetic responsive properties.
متن کاملThe Rea1 Tadpole Loses Its Tail
More than 170 assembly factors aid the construction and maturation of yeast ribosomes. After these factors' functions are completed, they must be released from preribosomes. In this issue, Ulbrich et al. (2009) describe a mechanochemical process through which the AAA ATPase Rea1 induces release of an assembly protein complex from preribosomes.
متن کاملFibonacci number of the tadpole graph
In 1982, Prodinger and Tichy defined the Fibonacci number of a graph G to be the number of independent sets of the graph G. They did so since the Fibonacci number of the path graph Pn is the Fibonacci number Fn+2 and the Fibonacci number of the cycle graph Cn is the Lucas number Ln. The tadpole graph Tn,k is the graph created by concatenating Cn and Pk with an edge from any vertex of Cn to a pe...
