Carbon 14 the radioactive nuclide used in dating fossils
Ecofeminism and ecopsychology are mentioned, for example, as are terms from organic gardening and permaculture.
Animals: the animal kingdom branches into the deuterostomes (mouth and anus develop separately) and the protostomes.
Animals are multicellular and possess mitochondria, a complex nervous system, and cells protected by a membrane and filled with complex organelles.
(By some accounts, the now-denuded Zagros Mountains in western Iran hosted this revolution.
"Zagros" is thought to derive from Zagreus, the Greek son of Zeus who was dismembered and eaten and later merged with Dionysus.) Modern agriculture largely relies on keeping ecosystems in perpetually immature states of succession in which chemically stimulated productivity remains high until the soils are too depleted to grow anything.
Is there any reason they too should not have somewhat the feeling I do there of coming suddenly out of the mountains into an alpine meadow, or a clearing in dense woods, or a plain after traversing rugged broken country?
Adaptation: how living things change what they do or what they are to survive in a particular environment.In this the organism is not a passive recipient of external circumstances; the relationship is interactive. Aggradation: a downward accumulation of stream-carried inorganic matter.
The corporatization of farming, resulting in a handful of very large non-local companies owning and managing--and in some cases ruining--millions of high-yield acres.Abandoned Wells: a hazard because wells left on vacated lands can channel water contaminated by pesticides and fertilizer straight down into the water table. Abrasion: the wearing away of rock surfaces by small particles moved by air or water.Abrasiveness also seems to be the one quality currently shared by most political appointees and prominent heads of state. Acid: a substance with a p H less than 7 due to prevalent hydrogen ions. The human stomach contains hydrochloric acid with a p H of 1; battery acid is stronger, but not by much. Acid Rain: precipitation heavy with nitric and sulfuric acid.It would be interesting to see a study on how many researchers feel separated from Ammonia: a gaseous compound of nitrogen and hydrogen (NH3) formed as a byproduct when bacteria decompose substances high in nitrogen.Compost piles thick with manure often emit ammonia when hot.The glossary that follows assumes a definition of ecology--the study of interactions between organisms and their environment--much wider than what fits under the field's habitual statistical persona.
