The Pigmentation of Cavernicolous Animals
THE present paper records the results of some analyses of carotenoid material in cave detritus, carried out as part of a research on the causes of pigment lack in the cave fauna. There is reason to suppose that the ancestral pigment of the numerous unpigmented cavernicolous Crustacea was the carotenoid pigment astacin, since closely related above-ground species frequently contain this pigment. ...

INTRODUCTION During an investigation of the causes of pigment lack in cave Crustacea, it seemed desirable to study the kind of pigmentation in related above-ground (epigean) forms. The colour of three species of Isopoda was found to be due to a melanin-like pigment in branched cells (Baldwin & Beatty, 1941). Two plant carotenoid pigments— cryptoxanthine and /J-carotene—were present throughout t...
متن کاملheoretical analysis of mechanisms that generate the pigmentation pattern f animals
Mechanisms of animal skin pigment pattern formation have long been of interest to developmental and mathematical biologists. Although there has been a well-studied theoretical hypothesis—the reaction–diffusion system—that is able to reproduce the variety of skin patterns, a lack of molecular evieywords:
