Autoecious

Listening is a more natural way of learning, when compared to reading. Written
language only began at around 3200 BC, but spoken language has existed long ago.

Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain

Now learn the vast amount of general knowledge available on Wikipedia through
audio (audio article). You could even learn subconsciously by playing the audio
while you are sleeping! If you are planning to listen a lot, you could try using
a bone conduction headphone, or a standard speaker instead of an earphone.

SUMMARY
=======
A heteroecious parasite is one that requires at least two hosts. The primary host is the host in which the parasite spends its adult life; the other is the secondary host.  Both the primary host and an unrelated alternate host are required for the parasite to complete its life cycle.  This can be contrasted with an autoecious parasite which can complete its life cycle on a single host species.  Many rust fungi are prime examples of a heteroecious life cycle.Parasitic heteroecious fungi include 

Gymnosporangium (Cedar-apple rust); the juniper is the primary (telial) host and the apple, pear or hawthorn is the secondary (aecial) host
Cronartium ribicola (White pine blister rust); the primary host are white pines, and currants the secondary.
Hemileia vastatrix (Coffee rust); Primary host is coffee plant;  Unknown alternate host
Puccinia graminis (Stem rust of wheat and Kentucky bluegrass);  Primary hosts include: Kentucky bluegrass, barley, and wheat; Common barberry is the alternate host.
Puccinia coronata (Crown Rust of Oats and Ryegrass); Oats are the primary host; Rhamnus spp. (Buckthorn) is alternate host.
Phakopsora meibomiae and P. pachyrhizi (Soybean Rust); Primary host is soybean and various legumes.  Unknown alternate host.
