The Ecology of the Endangered Dusky Gopher Frog (Rana Sevosa) and a Common Congener, the Southern Leopard Frog (Rana Sphenocephala)
… that compare the performance of an endangered (Rana sevosa) and a common (Rana sphenocephala) frog in changing habitats, to determine why these two species differ in their persistence. I include additional studies investigating the habitat requirements and behavior of R. sevosa. I found that …

Genetic variation of rana fuscigula in Southern Africa
… proceed. The experimental species is the trog Rana fuscigula, which has a range restricted to southern Namibia and South Africa. lt was thus possible to collect material from the edge of the distribution assuming that maximum genetic difference would be found between individuals at the edge of …

A study of lungs in Rana catesbeiana tadpoles
… respiration in the amphibians were made on Rana esculenta and Rana temporaria by Krogh (1904). He inserted a cannula connected to an air pump into the trachea and analyzed separately the air forced through the lungs by the pump and the air surrounding the frog. He was able to show that in R. …

Studies on Lymphokine Activity in the Amphibian Rana Temporaria
… which demonstrate that an anuran amphibian, Rana temporaria, is capable of elaborating a range of soluble mediators, analogous to mammalian lymphokines. In vitro stimulation of Rana temporaria leucocytes, with both antigens and mitogens, was employed. The supernatants from such stimulated …

Changes in gall bladder bile throughout development in Rana catesbeiana
The present study of Rana catesbeinana includes an analysis of the following throughout the course of post-embryonic development: the change in GI tract length and weight; the relative surfactant activity of the bile; the change in major bile pigments. The most rapid and profound morphological and …

The Conservation Ecology of Rana temporaria and Bufo bufo in Leicestershire
… previous decade. Breeding pond surveys revealed Rana temporaria to breed in areas with no rough vegetation in field ponds as small as 35 m3, but Bufo bufo only in ponds over 100 m3, in areas where scrub vegetation cover exceeded 2.5% of the total area. The densities of all ponds and R. temporaria …

A novel bioactive peptide from the skin secretion of Rana chensinensis
… AMP was identified from the skin secretion of Rana chensinensis by molecular cloning. The peptide encoding cDNA was successfully sequenced via bioinformatics tools, which revealed that the peptide is a member of temporin family, with the mature peptide sequence as FVDLKKIANIINSIF-NH2, namely …

The discovery of a novel peptide, QUB-2023, from Rana amurensis
… peptide QUB-2023, from the skin secretion of Rana amurensis. This was achieved by “shotgun” cloning. Solid-phase peptide synthesis (SPPS) and Reversed-Phase High Performance Liquid Chromatography (RP-HPLC) were applied to obtain a sufficient quantity of pure peptide replicate. The primary …

Discovery and functional evaluation of a host defense peptide from Rana amurensis
… study a new AMP from the skin secretions of Rana amurensis. A cDNA encoding a new ranatuerin precursor was successfully established through molecular cloning and Sanger sequencing, and the mature peptide sequence of the active form, QUB-2566 (GVLKGVGKNVSGSLLHQLKCLISGGC), was deduced from the …
