Chlorophyll Chlorosis can also be caused by pathogens including viruses, bacteria and fungal infections, or sap-sucking insects. Anthocyanins are other plant pigments. The absorbance pattern responsible for the red color of anthocyanins may be complementary to that of green chlorophyll in photosynthetically active tissues such as young "Quercus coccifera" leaves. It may protect the leaves from attacks by plant eaters that may be attracted by green color. The chlorophyll maps show milligrams of chlorophyll per cubic meter of seawater each month. Places where chlorophyll amounts were very low, indicating very low numbers of phytoplankton, are blue. Places where chlorophyll concentrations were
Parasites in fiction subservient puppets, able to crawl but unable to act independently; or the barnacle-like crustaceans that castrate their crab hosts, or grow into their brains, altering their behaviour to care for the young barnacles. All the same, a 2013 poll of scientists and engineers by "Popular Mechanics" magazine revealed that the parasite-based science fiction films "The War of the Worlds" (Byron Haskin, 1953) and "Alien" were among their top ten favourites. Several types of parasite, corresponding more or less accurately to some of those known in biology, are found in literature. These include haematophagic parasites (fictional vampires), parasitoids, behaviour-altering parasites, brood
