E. coli Biol.
Short for Escherichio coli. It is a common bacterium that normally resides in the human colon. Most strains of E. coli are harmless and has been studied intensively by geneticists and molecular biologists due to its small genome size and its ease of growth in the laboratory. However, a few strains of E. coli are dangerous. For example, E. coli O157:H7 can cause hemorrhagic diarrhea due to food poison by damaging the lining of the intestine.

ecliptic Astron.
The plane of the Earth's orbit round the Sun. In other words, it is the apparent path the Sun appears to move through the sky as a result of the Earth circling around it. It appears as a curved imaginary line in sky maps. Since most planets (and the Moon) of the Solar System move in rather similar plane, these celestial bodies, when visible in the sky, always stay close to the ecliptic line.

ecotone Ecol.
A transitional area between two distinct habitats. An area where ranges of the organisms in each habitat overlap and coexist. Some distinctive species may also found in this region but not within the different habitats.
