(2) Attendant to this
albinistic depigmentation process are psychic ramifications as discussed by Dr.
I also used several web-based bibliographic databases (EBSCOhost, JSTOR, Google Scholar, Harzing's Publish or Perish) and a web-based search engine (Google) to search for words or phrases (
albinistic, leucistic, piebald, melanistic, pelage color, etc.) specific to abnormal coloration in bighorn sheep and reviewed results of those searches for references to abnormal coloration in that species.
Additionally, there may also be present in several museum collections isabelline-colored specimens, where they may be incorrectly labeled as
albinistic. That said, albinisim does occur in Porcupines, but it is a different color variation, and hence expression of a different genetic mutation, than we observed.
Observation of
albinistic and leucistic Black mangabeys (Lophocebus aterrimus) within the Lomako-Yokokala Faunal Reserve, Democratic Republic of Congo.
To argue that it is a snow bunting x Lapland longspur hybrid, it is first necessary to establish that the individual is not a partially
albinistic (i.e., reduction in melanin) longspur.
Benton (1958) and Mengel and Jenkinson (1971) reported melanistic Red Squirrels, and Wood (1965) reported
albinistic individuals.
Recently, Long and Gehring (1995) reported a partially
albinistic masked shrew (Sorex cinereus) and argued persuasively that such bold white coloration contradicts Murray's rule of pattern development and size dependence.
