ist and co-author of the study, described how: initially you can see the distinct burrows they made, but after treatment there was less activity: some species just sat on top without moving much. This showed us how some organisms may be able to move more or less to regulate for these changes. So there could be a trade-off in behaviour.
The scientists may now find that certain species' are less tolerant, or even some genotypes within species are better able to tolerate changes. So, over time, sp
