In the late 1980s members of the public in the UK began reporting unusual mass mortalities of common frogs (Rana temporaria). (findaphd.com)

Here, we use sex-linked molecular markers to discover sex reversal in wild populations of green frogs ( Rana clamitans ) inhabiting ponds in either undeveloped, forested landscapes or in suburban neighborhoods. (peerj.com)
Investigation of the putative roles of these factors in the seasonality of freeze tolerance in vertebrates has been hampered by the rather modest limits for freezing survival in these organisms, as even fully cold-hardened frogs survive freezing to temperatures only as low as −4°C to −6°C. Recently, however, extreme freeze tolerance was documented in wood frogs ( Rana sylvatica ) endemic to Interior Alaska [ 10 ]. (hindawi.com)

However, they also found two common frogs ( Rana temporaria ) in dormouse nest boxes and one smooth newt and two great crested newts ( Triturus cristatus ) in tree cavities. (ecowatch.com)
Amphibians2
Complex mechanisms are involved in relation to the colour change in most amphibians, including the common frog ( Rana temporaria ) in relation to the background colour. (froglife.org)
Some amphibians also dramatically change colour during breeding, with the Moor frog ( Rana arvalis ) in continental Europe as the best example. (froglife.org)
Bufo2
Recently, 2 novel alloherpesviruses have been discovered: ranid herpesvirus 3 (RaHV3, Batravirus ranidallo3 ) in the common frog ( Rana temporaria ) and bufonid herpesvirus 1 in the common toad ( Bufo bufo ). (cdc.gov)

We detected RaHV3 DNA in free-ranging common frog ( Rana temporaria ) tadpoles, consistent with premetamorphic infection. (cdc.gov)
In 1992 we began an investigation into incidents of unusual and mass mortalities of the common frog (Rana temporaria) in Britain which were being reported unsolicited to us in increasing numbers by members of the public. (nih.gov)

Two cases of unusual mortality in Rana temporaria occurred at two high-mountain ponds (northwest Italy ) in April and May 2021. (bvsalud.org)
Eggs1
Using enzymatic removal of gelatinous coats (jelly envelope) surrounding the eggs of Rana temporaria , we tested the hypothesis that the jelly envelope acts as a sunscreen that protects embryos from harmful effects of UV-B radiation. (bioone.org)
