The data for the Bitemap project continues to pour in. We’ve also gotten some great multimedia from our partners showing their work. Here is a video by Katrin Reiss of Nord University featuring some really nice drone and underwater footage of their seines.
This week Bitemap was excited to receive our first data from the Southern Hemisphere! Our partners at Pontificia Universidad Catolica de Chile deployed squidpops and captured local fish consumers on video around Robinson Crusoe Island in the Juan Fernandez Archipelago.
As austral summer approaches we look forward to a lot more data from our southern colleagues to expand our ever-growing data set.
MarineGEO Director, Emmett Duffy, also presented Bitemap to an engaged crowd at the Western Society of Naturalists Conference in Monterey, California last week. We’re looking forward to more collaborations and engagement from the community as we begin to assemble a coherent picture of top-down pressure in nearshore ecosystems on a global scale.
Stay tuned for more updates. We will be contacting all participants in the new year with more information about analysis of the Bitemap data.
Greetings Bitemap participants and interested parties! The Bitemap project is off to a great start and we’ve received data from 15 locations so far (see map). Participation has been primarily from the west and east coasts of North and Central America, with one additional partner in Croatia.
So far we have seen interesting latitudinal differences emerging among our sites. Here are a few quick summary stats to give you a clearer picture of what the network has observed:
Overall we saw a decline in Squidpop consumption at higher latitudes after 24 hours in vegetated habitats only. We also saw a decline in fish community diversity in vegetated and unvegetated habitats at higher latitudes (Simpson), but no associated decline in vegetated habitat richness.
As we approach the austral summer we expect to see more submissions from around the world so stay tuned for updates. If you have collected data but haven’t submitted it yet, or if you have yet to collect your data, there is plenty of time for you to do so. Upload Squidpop data here on the google form, and email your fish community data to MarineGEO@si.edu. We’ll be in touch regarding analyses and publication preparation in the coming months.
We’re looking forward to hearing from you!

Welcome to the Bitemap Blog! We will keep you updated with the latest contributions and news coming from MarineGEO and the Bitemap Project.
We would like to thank our first round of contributors from VIMS, Northeastern University, Universidad Autonoma de Baja California, San Diego State University, and the University of Zadar who have submitted their data successfully. Here is a down and dirty output of some summary statistics:
Thanks to all our contributors and keep the data coming!
