If a non-native species is introduced into an ecosystem and it competes for the same ecological niche as a native species, what could be the outcome? the hawaiian islands are home to many endangered species. why do you think the hawaii department of agriculture is so strict about allowing non-native species onto the islands?

Based on the observation that only male crickets produce a song, you hypothesize that a male's song is a form of communication to potential mates. you set up a simple experiment to test this hypothesis. in the laboratory, you place a male snowy tree cricket in enclosure a, which is adjacent to enclosureb. in enclosure b, you place other insects, one at a time, and observe their responses to the male's song. the enclosures are designed so that the two insects being tested cannot see or smell each other, but sound is transmitted from enclosure a to enclosureb.
