Nature, 1933
ALBINISM in the common grass frog is a very rare phenomenon and as no mention is made of it in most works on albinism, its occurrence in four parts of England seems worth recording. The specimens I have seen recently came from Somersetshire, Wiltshire, Oxfordshire and Lancashire.

Spawning Date of the Common Frog
Nature, 1934IN a former communication1 I announced certain conclusions on the effect of the weather upon the spawning date of the common frog, Rana temporaries. Since then, a number of new facts have come to light.

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

Refrigerated storage of European common frog Rana temporaria oocytes
Cryobiology, 2018Reproduction technologies (RTs) for the storage and use of amphibian gametes have rapidly developed since the recognition of the amphibian conservation crisis in the late 20th Century. Of these RTs, the refrigerated storage of oocytes and sperm can help to achieve reliable pair-matching when unexpected deaths could lead to critical gaps in studbook ...

Photoprotection in tadpoles of the common frog, Rana temporaria
Journal of Photochemistry and Photobiology B: Biology, 2000The common frog, Rana temporaria, spawning at altitudes up to 2600 m, is potentially threatened by UVB radiation. In laboratory experiments we found a specifically UVB absorbing substance (UVAS) in the skin of tadpoles with maximum absorption between 290 and 300 nm. The production of UVAS is induced by both visible light and ultraviolet radiation.

Female‐biased sex ratios in subarctic common frogs
Journal of Zoology, 2008AbstractIn vertebrates with genetic sex determination, large deviations from the 1:1 sex ratio at the population level are rare and demand an explanation. We investigated adult sex‐ratio variation of common frogs Rana temporaria in two subarctic breeding ponds over a 6‐year (1999–2004) period using capture–mark–recapture (CMR) methods.

Some common names for Top End frogs
Northern Territory Naturalist, 2007Animals that are noticed because they are abundant or readily observed tend to acquire common names, and for many people these names are easier to remember than Latin (scientific) names. Fauna with specific, easily recognisable or distinguishing features also frequently have common names.
