An especially cheerful BioTIME Trinidad fieldwork team having just completed the final survey of the session, at the beautiful Acono river. This session has coincided with the dry season, and water levels have been noticeably lower. Seasonal differences such as this can also affect patterns of biodiversity over time, which is the focus of the BioTIME project. The next set of surveys will begin in August, by which time the rains will have returned.
