Genetic evidence indicates that the red deer, as traditionally defined, is a species group, ... Physiological effects of hunting red deer (Cervus elaphus).
Hajji and others, and Hundertmark & Van Daele, studied the current population statuses of past founder effects in Corsican red deer and Alaskan elk, respectively. Corsican red deer are still listed as an endangered species, decades after a severe bottleneck. They inhabit the Tyrrhenian islands and surrounding mainlands currently, and before the ...
Chronic wasting disease (CWD), sometimes called zombie deer disease, is a transmissible spongiform encephalopathy (TSE) affecting deer.TSEs are a family of diseases thought to be caused by misfolded proteins called prions and include similar diseases such as BSE (mad cow disease) in cattle, Creutzfeldt–Jakob disease (CJD) in humans, and scrapie in sheep.

Genetic mutations which cause an absence of a normal pigment and/or excessive production of others [2] Diet, as in bees feeding on "bright red corn syrup" used in maraschino cherry manufacturing. [3] Erythrism in katydids has been occasionally observed. The coloring might be a camouflage that helps some members of the species survive on red ...
Industrial melanism is an evolutionary effect in insects such as the peppered moth, Biston betularia in areas subject to industrial pollution. Darker pigmented individuals are favored by natural selection, apparently because they are better camouflaged against polluted backgrounds. When pollution was later reduced, lighter forms regained the ...
Sika deer: Sika deer were introduced into Western Europe, and they reproduce easily with the native red deer. This translocation of Sika deer has led to introgression and there are no longer "pure" red deer in the region, and all can be classified as hybrids.
Leucism is a rare genetic pattern that causes a reduction in the pigment of an animal's hair and skin. The natural colour of the red deer ranges from dark red to brown.They are often thought to be albinos; however, unlike albinos, who have characteristically red eyes, deer with leucism have normal colouring in their eyes.
In the third edition of Mammal Species of the World from 2005, only the red deer (C. elaphus) and sika deer (C. nippon) were recognized as species in the genus Cervus. [1] Genetic and morphological evidence suggest more species should be recognized. [2] [3] For example, the species Cervus canadensis (elk/wapiti) is considered a separate species ...
