Second, the next question is how a molecular species interacts with electromagnetic radiation.

Rarely, the reverse can occur, and two or more fungal species can interact to form the same lichen.

In other cases species interact with each other more directly.

Because the different species interact, changes in populations affect one another synergistically to determine community structure.

A few provide wild species (such as pythons or baby big cats) to interact with, but these are rare and usually found outside of Western nations.

These species often lived and interacted in the same area at the same time.

"It's hard for me to understand that two species in neighboring star systems didn't interact without there being some hostility between them."

In many cases, two species will interact differently under different conditions.

"Our teams should be augmented with cultural specialists and linguists, people who are trained to handle the rough spots when different species interact."

This year, the American-Brazilian team plans to study how the diverse species interact in such close quarters.
