Sepiapterin reductase (Spra and Sprb) regulate carotenoid and pteridine metabolism influencing the koi carp (Cyprinus carpio L.) coloration

The evolution of teleost Dehydrators coloration is strongly linked with the fish-specific genome duplication (FSGD).Sepiapterin reductase (Spr) is commonly required in pteridine pigment synthesis and two paralogs are found in teleosts.However, the functions of spra and sprb in pigmentation have not been completely elucidated.Here we found that spra

Assessing the Use of Artificial Hibernacula by the Great Crested Newt (Triturus cristatus) and Smooth Newt (Lissotriton vulgaris) in Cold Climate in Southeast Norway

Construction of artificial overwintering habitats, hibernacula, or newt hotels, is an important mitigation measure for newt populations in urban and agricultural areas.We have monitored the use of four artificial hotels Cream Pump built in September 2011 close to a 6000 m2 breeding pond in Norway.The four hotels ranged from 1.6 to 12.4 m3 and were
