Common Frog Rana temporaria Linneaus 1758 Distribution (Figure 5). Included records from Artportalen (N=2000): a ubiquitous species for which all reported records have been included.Any rare confusion with Rana arvalis would not change the overall picture of distribution or abundance.

Cerebellar afferents in the frogs, Rana esculenta and Rana temporaria
Cell and Tissue Research, 1984Afferents to the cerebellum in frogs (Rana esculenta, Rana temporaria) were studied by use of retrograde transport of horseradish peroxidase. Following injections restricted to the molecular layer of the cerebellum cell labelling was found in the contralateral inferior olive and the ventral portion of the caudal medullary raphe.

Temperature and immobility reaction in Rana temporaria
Behavioural Processes, 1982Experiments were conducted on two groups of Rana temporaria acclimatized to 7°C and to 14°C. Two hours prior to the experiments the animals were divided into six groups of 40 subjects each and placed in containers at temperatures of 5°, 10°, 15°, 20°, 25° and 30°C.

Toxicity of tetrachlorwinfos to Rana temporaria l.
Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 19931. Changes in the erythrocyte system of frogs poisoned with tetrachlorwinfos depend on the sex of the animals and the dose of pesticide applied. They are a result of the pathomorphological changes due to translocation of fluids from the tissues to the circulation and swelling of the blood cells. 2. Changes in the leucocyte system of frogs are caused by

Rhodanese (thiosulfate:cyanide sulfurtransferase) from frog Rana temporaria
Journal of Chromatography B: Biomedical Sciences and Applications, 2000The molecular mass of rhodanese from the mitochondrial fraction of frog Rana temporaria liver, equaling 8.7 kDa, was determined by high-performance size exclusion chromatography (HP-SEC). The considerable difference in molecular weight and the lack of common antigenic determinants between frog liver rhodanese and bovine rhodanese suggest the occurrence

Retinoscopic and neurophysiological refractometry in rana temporaria
Pfl�gers Archiv European Journal of Physiology, 1972If frogs are measured by objective refractometry one finds a hyperopia of 6 D to 9 D. Therefore we investigated the neurophysiological state of refraction of the immobilized rana temporaria using the technique of extracellular recording. In the superficial neuropil the neural activity of 32 recorded neurons showed no dependence on the state of ...

Journal of Genetics, 1949
White frog spawn gave rise to black-eyed white tadpoles, which later darkened, and developed into normal frogs. The latter produced normal tadpoles, some of which developed into albino adults. The facts can be explained if albinism is recessive, but the dominant allelomorphic gene found in normal frogs produces enough pigment in the eggs of ...

The Common Frog Rana temporaria
1991The oocytes, embryos, and larvae of Rana temporaria have long been traditional subjects of diverse experimental embryological studies. Experimental embryologists have often used the embryos of R. temporaria for studies concerning the mechanisms of development. In the first half of this century experiments were carried out on eggs collected from natural

MHC zygosity in the frog, Rana temporaria
Immunogenetics, 1984The major histocompatibility complex (MHC) zygosity of the field-collected frogs, Rana temporaria, was detected by progeny testing. Groups of sibling tadpoles were grafted with intrafamilial tail-tip allografts and the ratio of rapidly rejected allografts to slowly rejected ones was estimated.
