We are proud to share news of a new scientific publication using REEF data that was recently published in the top-tier science journal, Ecology. The paper, "Demographic modeling of citizen science data informs habitat preferences and population dynamics of recovering fishes", was co-authored by fisheries scientists from NOAA Fisheries and Scripps Institution of Oceanography, along with REEF's Director of Science, Dr. Christy Pattengill-Semmens. The authors combine citizen science data collected at large scales from REEF's Volunteer Fish Survey Project with recently developed statistical demographic modeling techniques. The model analysis included two managed reef fishes in the Gulf of Mexico, Goliath Grouper and Mutton Snapper, to estimate population trends, habitat associations, and interannual variability in recruitment. The results identify strong preferences for artificial structure for the recovering Goliath Grouper, while revealing little evidence of either habitat associations or trends in abundance for Mutton Snapper. Results also highlight the utility and management benefits of combining demographic population models and citizen science data. Visit REEF's Publications page to read more about this study, access the original paper, and information on the over 50 other scientific publications that have included REEF programs and data.
Working with leading scientists, REEF's lionfish field work is paying off in valuable information needed to address this key issue. Information from the five Bahamas projects conducted thus far this year is being used to help determine the range and extent of the lionfish invasion, as well as to address key questions on age/ growth, reproduction, genetics, parasites and habitat preference.
To date, more than 400 fish have been collected and shipped to the NOAA research lab in Beaufort NC and more than 500 sightings have been documented in the Bahamas. Data on length, plumage and stomach content have been gathered in the field, and samples for genetics and age/growth studies have been shipped to researchers. REEF has worked in close partnership with the College of the Bahamas, researchers at UNCW, and Salisbury University, and local dive operators Bruce Purdy and Stuart Cove in gathering and analyzing the data.
Interesting data to date include:
Just before the holidays, REEF was saddened to learn of the passing of long-time volunteer and friend, Chile Ridley of Bonaire. Our thoughts are with his family and friends, especially his wife, Linda. The following article by Buddy Stockwell was published in the Caribbean Compass.
"On December 16, 2007 , the Cruising Community, the Island of Bonaire, and Mother Earth all lost one of their most wonderful, talented, and trusted friends. Edward Alton Ridley, known to all as " Chile" Ridley, took his own life at the age of 58. Chile was born in Valentine, Texas, and had battled the disease of depression all of his life. He is survived by his wife, Linda Ridley of Marfa, Texas . The Ridley's began their Cruising life aboard their Valiant 42 "Natural Selection" by departing Galveston in 1998 and sailing to St. Petersburg, Florida , where their new Valiant was part of the 1998 boat show. Thereafter, they cruised down the Eastern Caribbean , finally arriving in Bonaire five years later on Valentine's Day of 2003. As avid SCUBA divers, both Chile and Linda instantly fell in love with Bonaire and remained there as residents living aboard "Natural Selection." Chile was Manager of Bonaire's Capture Photo and also worked as a Dive Master. Most important, he was an indispensable volunteer for environmental organizations such as REEF, STINAPA and the Bonaire Seaturtle Conservation Project. Chile completed 300 Level 5 surveys for REEF, collected hundreds of amazing underwater images on film, and completed almost 2,000 dives. Chile's "True Grit" Texas spirit, fine character, and exceptional skills combined to make him an unflagging Champion of the environment like no other. Loved by all, Chile was not just a gentleman but a gentle man, always willing to lend a hand and always the first to volunteer. He will be missed by all who knew him, including all of the beautiful sea creatures of Bonaire that he loved so well and fought so hard to protect. The family asks that in lieu of cards or flowers, donations should be made in his name to support the Sea Turtle Conservation Project by visiting https://www.supportbonaire.org or to www.REEF.org for the fish survey projects."
REEF will separate our online dataentry interface for New England region from the tropical western Atlantic (TWA) where it currently resides, in the coming month. Just in time for the Great Annual Fish Count, for more information, please contact firstname.lastname@example.org or call 305-852-0030. We hope that this will facilitate an increase in the New England region survey efforts starting this summer. In the next few weeks, login at http://www.reef.org/dataentry/login.php and you will be able to select New England for uploading New England fish surveys. There are a few New England members who are willing to assist and guide those REEF members who are interested in participating in New England surveys.
REEF staff and volunteers are attending several events in the Northwest this winter and spring to spread the word about the Volunteer Survey Project. These include scientific conferences and dive shows. REEF volunteer and instructor, Janna Nichols, represented REEF at the Puget Sound Georgia Basin (PSGB) Ecosystem Conference last month in Seattle, Washington. Over 1,000 scientists, decision-makers and others attended the PSGB and the overall conference theme was to share knowledge and commit to action to protect the region's marine environment. Janna presented posters on two of REEF's important programs in the Pacific Northwest, tracking the presence and spread of invasive tunicates and the long-term monitoring of sub-tidal fish and invertebrates in the Olympic Coast National Marine Sanctuary.
If you weren't able to attend the PSGB Conference, REEF is participating in two upcoming events in Washington. The first is a workshop organized by the Centers for Ocean Sciences Education Excellence (COSEE) and others, "Exploring the Spectrum of Citizen Science". The workshop is being held April 10-11 at Fort Wordon State Park and will bring together many citizen science practitioners to discuss what make successful programs. Later that month, come visit the REEF booth at the Northwest Dive and Travel Expo in Tacoma, April 25 & 26th. REEF volunteers and Director of Science, Dr. Christy Pattengill-Semmens, will be at the booth to spread the word about REEF. We'll have survey materials and guide books on hand and will be presenting a seminar, "REEF: Diving That Counts" on Saturday afternoon at 2pm. See you there!
The REEF Pacific Region, which includes California through British Columbia, continues to be one of our most active areas. This is thanks to funding support from several West Coast foundations as well as partnerships with some great organizations. REEF survey and identification training opportunities abound, long-term monitoring projects in several National Marine Sanctuaries continue, the number of REEF Expert surveyors is increasing, and REEF data and projects are being presented at conferences and used by scientists and agencies. REEF greatly appreciates the continued support of several West Coast funders, including The Russell Family Foundation and the Sustainable Path Foundation, as well as our dedicated volunteers for making this continued success possible. If you are in the Pacific Northwest, check out the REEF PNW Critter Watchers webpage, which connects area REEF surveyors for training and surveying opportunities.
There's still space in some of the fish and invertebrate identification and REEF survey training classes being held next month in Southern California. Classes will be held June 24, 25 and 26 in Dana Point and Long Beach. To find out more, see this article in last month's REEF-in-Brief. Classes are informative, fun and free, but registration is required. To register go to: http://www.pnwscuba.com/critterwatchers/calclasses.htm.
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:
- A biologist from Fisheries and Oceans Canada is evaluating fish and invertebrate populations in Race Rocks outside of Victoria BC, in preparation for the establishment of an Marine Protected Area.
- A researcher at the University of Texas is conducting a large-scale study of evolutionary ecology in Caribbean reef fishes using REEF data and other publically available sources of morphological and phylogenetic data.
- A scientist from the Florida Fish & Wildlife Conservation Commission is conducting an analysis on goliath grouper populations for a NOAA Fisheries stock assessment.
- A researcher from University of East Anglia is using the entire REEF Caribbean dataset to conduct a large-scale analysis of species diversity.
REEF is proud to partner with over 130 dive shops, dive clubs, individuals, and other organizations as REEF Field Stations
This month we feature Sea Saba, a top-notch dive operator located on a small Caribbean island devoid of beaches, but abundant in spectacular dive sites! The island of Saba is known for its unspoiled natural beauty and lack of development- the island has fewer than 2,000 residents. Dive shop owners, Lynn and John, have made scuba diving, travel, and photography their life for well over 2 decades. Some time ago, while exploring a rainforest in Peru with an exceptionally knowledgeable and enthusiastic guide, Lynn realized that there aren’t enough scuba guides in the industry who are highly knowledgeable about the marine life and habitats they work in. To quote her, “Certainly professional and safety standards are important but sadly, far too many dive guides are actually poor guides.”
Working with the REEF program is one great tool utilized by Sea Saba to continue to improve the knowledge base of their dive instructors. Dive staff members are frequently reminded that their core function is to be great guides, and newly hired dive staff are required to become REEF Level 3 surveyors within 60 days! “It’s a win/win/win. We’re making a concerted effort to ensure a great dive experience is had by all our visitors but also by our staff. If we can engage each guide to be more aware and knowledgeable and share this information with our diving guests, dive guides avoid burnout. The enthusiasm is contagious.” says Lynn.
Sea Saba understands and shares REEF’s mission to educate, enlist, and engage divers in marine conservation efforts. In Lynn’s words, “Fish identification skills are a stepping stone in understanding our underwater environment. By sharing knowledge, we not only create better surface interval conversations, we can hope each diver is also an advocate to use what power he/she has to protect this realm: the coral, the fish, the reef, the ocean…our planet.”
Sea Saba hosted the first REEF Field Survey of the year in March and they made sure our trip season got off to a great start - participants confirmed over 150 species sightings during the week, including rare finds such as yellowcheek basslets, punk blennies, and a hammerhead shark! Our team of ten was well taken care of by the excellent divemasters and staff of Sea Saba, many of whom are active surveyors throughout the Saba Marine Park surrounding this petite island. The natural beauty of Saba was the perfect setting for our diving (and hiking) adventure.
