Data generated by the REEF Volunteer Fish Survey Project provide an unparalleled opportunity to examine patterns in reef fish diversity (the number and types of species) at the scales of reefs, regions, and even an entire ocean basin. Authors of one recent scientific study took advantage of the over 25,000 Expert REEF surveys conducted at 80 sites from 6 Caribbean ecoregions over 17 years. The authors of the paper, which was recently published in the journal PLoS ONE, used the REEF data to evaluate patterns of biodiversity across many spatial scales (from individual sites to ecoregions). They also incorporated factors such as fisheries impacts and how connected different regions are to each other through ocean currents. They compared levels of different types of diversity-- alpha diversity (α-diversity) that explains local diversity (the number of species found in a given place), and beta diversity (β-diversity) that explains the difference in diversity among sites. Their results showed that fish assemblages are more homogenous than expected, particularly at the ecoregion scale. Within each ecoregion, diversity was mainly attributed to alpha diversity, indicating that fishes within each ecoregion are a subsample of the same species pool. Studies like this one that examine regional patterns of diversity in coral reef systems are important because of declining biodiversity in many areas.

Every month, scientists, government agencies, and other groups request raw data from REEF’s Fish Survey Project database. Here is a sampling of who has asked for REEF data recently and what they are using it for:
- Scientists from NOAA’s Office of Protected Resources are using REEF data to evaluate populations of seabass and grouper in the Caribbean.
- A scientist from the University of Washington School of Marine and Environmental Affairs is using REEF data on fishes and invertebrates to evaluate MPAs in the Puget Sound.
- A professor from California State San Luis Obispo is using REEF data to evaluate populations of three large parrotfish species in the Caribbean (Blue, Midnight, Rainbow).
Earlier this month, REEF Director of Science, Dr. Christy Pattengill-Semmens, participated in the first of a series of workshops to be held this Fall to analyze REEF and other data gathered from the Channel Islands Marine Protected Areas (MPAs). Originally established in 2003 (and then expanded to include Federal waters earlier this year), this network of no-take marine reserves protects 318 square miles around the northern five Channel Islands off the coast of California. In 2008, the California Fish and Game Commission will conduct a 5-year review of the MPAs to evaluate the effectiveness of the reserve network. The results from the evaluation will inform future decisions made by the Commission under California's Marine Life Protection Act. The data group workshops, held at the National Center for Ecological Analysis and Synthesis, will culminate in a series of publications summarizing the cumulative efforts of dozens of monitoring programs within the Channel Islands MPAs, with an emphasis on analyses that can best address key management questions concerning the reserves. These results will be presented during a special symposium associated with the California Islands Symposium.
Coincident with the establishment of the marine reserves in 2003, REEF initiated a coordinated monitoring program at specific sites inside and outside of the reserves to complement the ongoing survey activities in the area by REEF members. Surveyors on REEF's Pacific Advanced Assessment Team participate in annual REEF cruises aboard the Channel Islands National Marine Sanctuary (CINMS) vessel R/V Shearwater, and this project has generated over 800 surveys to date. These data, along with an additional 750 REEF surveys that had been conducted around the islands prior to 2003, will provide information on the fish assemblages (and more recently key invertebrate and algae species) of the Channel Islands.

On Tuesday, February 26 and Wednesday, March 12, REEF hosted two citizen science panel discussions about how volunteers contribute to understanding and preserving the Florida Keys environment. The first discussion, held in Key Largo, featured speakers from the Breeding Bird Survey project, Coral Restoration Foundation, and John Pennekamp State Park native plant nursery. The second event, held in Key West, featured speakers from The Nature Conservancy, Mote Marine Laboratory and the National Weather Service. Both discussions were led by guest speaker Rick Bonney, a pioneer in the citizen science field from the Cornell Lab of Ornithology in Ithaca, NY. Leda Cunningham presented on the REEF Volunteer Survey Project.
Forty-two people participated in the discussions, most of whom were themselves volunteers in a local or national citizen science project. "Most scientists usually only get to attend 'niche' meetings, where everyone in the room is talking about variations of the same subject matter," said Alison Higgins of The Nature Conservancy. "What was amazing about REEF's Citizen Science symposium is that the approach was the same (engaging the public in collecting important observations), but the subjects were varied. I specialize in land conservation issues, but got to brainstorm and engage with fish, bird and weather scientists - It was a really great and necessary experience"
Each discussion group brainstormed next steps for the citizen science movement in the Florida Keys. Ideas included forming an informal coalition of citizen science projects, doing integrated data analysis across project taxa (effect of weather on fish or bird population trends, e.g.), starting a regular citizen science column in a local newspaper and developing a citizen science booklet for residents and visitors to learn about local projects.

Where people get fish smarts! Over the weekend of October 12, six REEF Level 1 & 2 surveyors got a chance to become Level 3 Advanced surveyors and increase our fish smarts with Paul Humann, Ned and Anna DeLoach and Lad Akins. I personally became a REEF customer for this event and participated in the classroom, the fun, hanging out with Paul, Ned and Anna at the cookout, diving with Lad as he found new (for us) exciting additions to our life list and took the 100 Fish - Level 3 test (good thing I passed).
As part of the event, the first of its kind, we invited surveyors who had submitted 25 or more surveys but were still rated Introductory/Novice. Linda Crouse, Kelly Drinnen, Lureen Ferretti, Karen Hausheer and Dawn Vigo were the very fist participants in REEF Fish Academy. The weekend included classroom sessions, survey dives, and evening socials. Anna DeLoach shared REEF’s vision for this new training program with our participants, “We are looking to provide our enthusiastic REEF members with a way to share their passion and knowledge for Fish Watching. REEF Fish Academy is designed to tap into this enthusiasm and provide our members a way to become mentors for others, spreading the word about fish watching and surveying. REEF Fish Academy graduates are ready share the fun and excitement of fish ID and show people what fish surveying and contributing to REEF’s database is all about - making dives that count”.
The diving and a cookout were provided by Horizon Divers, one of REEF’s valued partners here in the local community. We had two great days of diving and over 80 species of fish sighted during the intensively fish orientated weekend. We are already planning for our next REEF Fish Academy, so keep an eye out for your invitation – coming soon.
Congratulation to Lureen Ferretti – who even passed her Level 4 Fish Test during the weekend and is now an Expert Surveyor. Special thanks to the participants for their support, coming to Key Largo to dive with us, their enthusiasm and all the great feedback and suggestions. It was a fantastic weekend.

The first Bahamas Lionfish Derby, held on June 6 at the Green Turtle Club in Abaco, was a great success on many fronts. This test case for the Bahamas government was the first to allow (by special permit) the use of compressed air and spearing to remove lionfish in a derby type event. Organized by Abaco and Palm Beach resident Bobbie Lindsay and REEF, the one-day event drew 26 registered teams and brought in 1, 408 lionfish. Over $5,000 in prize money was awarded including $2,000 for the most fish by any team – 289 by team White Roach from Abaco. The largest fish award went to Team Panga with a 349mm fish and the smallest fish was brought in by Big T with a 57mm juvenile. Pre-event talks, including a school wide talk to the Amy Roberts elementary school, were well attended and generated significant awareness of the lionfish issue. Over 200 participants, residents and visitors attended the scoring and awards banquet and were treated to a lionfish tasting as well.
This is the first large scale event aimed at controlling lionfish populations in the Caribbean. More events are currently being organized in other areas and dates are being set for next year’s 2nd annual Abaco Derby. Special thanks goes out to the Green Turtle Club, Brendal’s Dive Shop and all of the great teams and volunteers who participated in the event. A great time was had by all and the lionfish population around Abaco was dramatically reduced.

Scientists and project volunteers from REEF and our partner institutions, the Cayman Islands Department of the Environment and Oregon State University, are getting ready for another year of the Grouper Moon Project. The team will be in the field for two weeks beginning on the full moon, January 30. Since 2001, REEF has led the Grouper Moon Project, a multi-faceted, collaborative research effort in the Cayman Islands aimed at better understanding Nassau grouper reproduction and the role that marine reserves can play in the long-term protection of this endangered species.
In 2003 the Cayman Island Marine Conservation Board instituted an 8-year fishing ban on Nassau grouper at all historically known aggregation sites in the Cayman Islands. This followed the discovery by fisherman of 7,000 aggregating Nassau grouper on the west end of Little Cayman in 2001 and the subsequent harvest of 4,000 of those fish over two spawning seasons. At the time, all other known Nassau grouper aggregations in the Cayman Islands had become inactive due to over-harvest. Thanks to a three-year grant awarded in 2008 by the Lenfest Ocean Program of the Pew Charitable Trusts, REEF is conducting research through the Grouper Moon Project to evaluate the current status of the Cayman Islands spawning aggregations and the effect of these harvest protections -- “The reproductive biology of remnant Nassau grouper stocks: implications for Cayman Islands Marine Protected Area (MPA) management”.
The broad goals for the 2010 spawning season are to continue monitoring recovery in the large spawning aggregation on Little Cayman, and to expand research into the fate of remnant spawning aggregations on Cayman Brac and Grand Cayman. Watch future issues of REEF-in-Brief for field season results and what's next for the protection of spawning aggregations in the Cayman Islands as the current harvest ban is due to expire.

Some of the best dive sites for fishwatching are in the least obvious places. The Blue Heron Bridge in Palm Beach, Florida, is one such biological hotspot. This is a top dive destination for sighting unusual species that can be added to your lifelist. Mike Phelan, REEF Expert surveyor, and two other REEF members, often dive this site. The day before Thanksgiving, they were treated to quite a sight – a large school of Cownose Rays! This is a rare sighting in Florida, but it’s just another day at the Blue Heron Bridge. Some of the more unusual and recent sightings include the Blackwing Searobin, Roughtail Ray, Northern Stargazer, Orangespotted Blenny, Polkadot Batfish, and the Chain Pipefish. The bridge traverses a small island located in the inland waterway near the Lake Worth inlet. The dive sites consist of a variety of eco-niches such as sand, shell rubble, sea grass, algae hydroid fields, sailboat mooring lines and anchors and of course bridge pilings and concrete rubble. The Blue Heron Bridge has over 282 species recorded in the REEF database and the number is increasing monthly (click here to see the full list).
The actual dive site is a local county park named Phil Foster Park that is protected with a no-take ordinance. All dives are shore-based and must be timed with the high tide. The dive can be safely done by entering the water one hour before high tide and exiting one hour after high tide. Depths range from 8 -17 feet and the water is usually clear even if the off-shore ocean is rough. Remember to bring a dive flag. Many divers combine their Blue Heron trip with some local Jupiter off-shore diving to witness the Goliath grouper aggregations in August or September, Loggerhead, Green, and Leatherback turtle nesting during the spring or the Lemon shark aggregation in the winter. This is certainly a dive site to be thankful for!
