Protective resemblance is used by prey to avoid predation. It includes special protective resemblance, now called mimesis, where the whole animal looks like some other object, for example when a caterpillar resembles a twig or a bird dropping. In general protective resemblance, now called crypsis, the animal’s texture blends with the background, for example when a moth’s color and pattern blend in with tree bark.
Pigments are colored chemicals (such as melanin) in animal tissues.
wholly new at the time. It strongly supported Darwin’s theory of sexual selection, arguing that the obvious differences between male and female birds such as the Argus pheasant were selected by the females, pointing out that bright male plumage was found only in species ”which court by day”.The book introduced the concept of frequency-dependent selection, as when edible mimics are less frequent than the distasteful models whose colors and patterns they copy. In the book, Poulton also coined the term aposematism for warning coloration, which he identified in widely differing animal groups including mammals (such as the skunk), bees and wasps, beetles, and butterflies.
Fruits are the means by which angiosperms disseminate seeds. Edible fruits, in particular, have propagated with the movements of humans and animals in a symbiotic relationship as a means for seed dispersal and nutrition; in fact, humans and many animals have become dependent on fruits as a source of food. Accordingly, fruits account for a substantial fraction of the world’s agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings.
My husband gave me your Calming Doodles coloring book for Christmas and I LOVE it. The stiff backer board is perfect to support the wonderful heavy weight of the paper. I use markers and love the finish and smooth look I get on the paper. I am a card maker and plan to cut each sheet into 1/4’s to make cards out of each piece. Love having a coloring book I can do something with instead of having lots of white space with an image in the middle of each page. You’ve got a winner here to be sure.
Hugh Bamford Cott’s 500-page book Adaptive Coloration in Animals, published in wartime 1940, systematically described the principles of camouflage and mimicry. The book contains hundreds of examples, over a hundred photographs and Cott’s own accurate and artistic drawings, and 27 pages of references. Cott focussed especially on ”maximum disruptive contrast”, the kind of patterning used in military camouflage such as disruptive pattern material. Indeed, Cott describes such applications
