Technique for studying arthropod and microbial communities within tree tissues.

Phloem tissues of pine are habitats for many thousands of organisms. Arthropods and microbes use phloem and cambium tissues to seek mates, lay eggs, rear young, feed, or hide from natural enemies or harsh environmental conditions outside of the tree. Organisms that persist within the phloem habitat are difficult to observe given their location under bark.

Using acoustic technology to reduce bark beetle reproduction.

Background: Acoustic signals play a critical role in mate choice, species recognition, communication, territoriality, predator escape and prey selection. Bark beetles, which are significant disturbance agents of forests, produce a variety of acoustic signals.

Results: A bioacoustic approach to reducing bark beetle reproduction within wood tissues was explored.
