The second pulse of the extinction is marked by a sharp temperature spike an...
متن کاملWound Care in Reptiles
Reptiles are often presented to wildlife carers with various types and grades of wounds. Reptile wound healing rates are comparatively slower when compared to healing rates in mammals and birds. With appropriate wound management we hope to significantly reduce wound healing rates. How we manage a reptile‟s wounds will impact on the healing rate and thus influence the reptile‟s required time in ...
