World-wide declines in shark and ray populations have prompted the need for a better understanding of their patterns of distribution and abundance. While much of the focus has been on the larger species of sharks, little attention had been paid to the most frequently sighted elasmobranch species in the greater-Caribbean, the yellow stingray (Urobatis jamaicensis). Despite being relatively common and listed as Least Concern on the IUCN Red List, little was known about the status of this species. Unfortunately, it has been quietly declining. Dr. Christine Ward-Paige and her colleagues at Dalhousie University worked with REEF's Director of Science, Dr. Christy Pattengill-Semmens, to examine the status of yellow stingray. The results of this study were recently published in the scientific journal, Environmental Biology of Fishes. Click here to read the paper.
The study used 83,940 surveys collected by REEF surveyors in the western Atlantic. In total, yellow stingrays were observed on 5,658 surveys (6.7% sighting frequency) with the highest occurrence in the regions surrounding Cuba. Overall, sighting frequency declined from 20.5% in 1994 to 4.7% in 2007. However, these trends were not consistent in all regions. The strongest decline occurred in the Florida Keys, the most sampled region, where trends were similar among all areas, habitats and depths. Possible explanations for these changes include habitat degradation, exploitation (this species is collected for medical research and the aquarium trade), and changes in trophic interactions. The results of the study suggest large-scale changes in yellow stingray abundance that have been unnoticed by the scientific community. This study also highlights the value of non-scientific divers for collecting data that can be used to understand population trends of otherwise poorly studied species.

REEF members are at the heart of our grassroots marine conservation programs. Over 43,000 divers, snorkelers, students, and armchair naturalists stand behind our mission.
This month we feature Patricia Broom (REEF member since 2004). Pat is a member of REEF's Advanced Assessment Team in the Tropical Western Atlantic and has conducted 277 surveys in three of REEF's regions, including some of the first in our newest region, the South Pacific. Here's what Pat had to say about REEF:
When and how did you first volunteer with REEF or become a REEF member?
About ten years ago while reading a favorite dive magazine I noticed an announcement about an introductory fish identification trip sponsored by REEF and led by Paul Humann. The love of REEF was born!! I responded to the advertisement, encouraged my brother to join me and attended that Field Survey trip. We joined a group of equally dedicated divers eager as we to learn about fish and how to identify them. Paul was a great teacher, very patient and concerned that we not only learn about fish but care about them and the ocean we love.
If you have been on a REEF Field Survey, where and what was a trip highlight?
One of my most memorable surveying moments occurred that week on Paul's trip. On a night dive of a very old wreck with exposed wooden beams I saw my first queen parrotfish in their nighttime cocoons. Each parrot fish occupied a space between two beams framed by basket stars in full bloom. It was a magical sight. I try to take two or three REEF trips a year, they are a great way to learn more and dive with great people. In addition to the regular ID trips, I have really enjoyed the REEF Behavior Trips that are led by Ned and Anna DeLoach. It really completes the learning experience! It is a beautiful sight to watch damselfish guard their algae gardens from predation, observe cooperative hunting, or watch a three foot Midnight Parrotfish at a cleaning station with open mouth and flared gills.
What inspires you to complete REEF surveys?
Prior to that introductory course, I had been diving the Caribbean for twenty plus years. I witnessed the decline in fish numbers and species as well as reef degradation and wondered how many more years I could dive before there was nothing to see! REEF offered me a reason to continue diving, now there was opportunity to give back and enjoy diving again.
Do you have a favorite local (or not) REEF field station or dive shop?
I have found great enjoyment in Cozumel at the REEF Field Station at Aqua Safari, led by Sheryl Shea. She is a gifted teacher determined to make advanced assessment divers of all of us! It just so happens a few of my favorite fish are in Cozumel, the Splendid Toadfish, Sargassum Triggerfish, and Cherubfish, to name a few.

REEF is once again partnering with CEDAM International to support an educator to participate in one of our REEF Trips. The selected Lloyd Bridges Scholar will join Paul Humann on the Little Cayman Field Survey in July 2013. The goal of the scholarship program is two-fold: One, to have educators experience the wonders of the underwater world and then be able to share these wonders with his or her students or constituents. Two, to have these inspired individuals go out and do what they can to help protect one of the world’s most fragile ecosystems. To be eligible, applicants must be a certified scuba diver, a teacher (elementary or secondary level), or actively engaged in an education program at an institution or environmental organization, such as an aquarium, science center, or relevant non-profit organization. More information and application information is posted on the CEDAM website.
The 2013 REEF Trips Schedule includes destinations in the Caribbean, Canada, and tropical Pacific. These trips offer a great introduction to fish identification for novice fishwatchers, and are a fun way for experienced surveyors to build their life list while interacting with fellow fishwatchers.

Thanks to a grant from The Russell Family Foundation, we are in the middle of a year-long initiative to actively engage new REEF surveyors in the region and to provide incentive to our existing surveyors to stay active and move up through the ranks of the REEF Experience Level system. We have teamed up with PNW REEF instructor, Janna Nichols, to coordinate a series of free training workshops throughout Washington and Oregon. These seminars will cover the Introductory REEF Fish Identification training, the REEF Pacific Northwest Invertebrate Identification training, and a NEW Advanced Fish Identification training program. Visit the Pacific Northwest Critter Watchers Webpage to see a complete list of classes. The project will also support a series of REEF survey day trips on area dive charters that will be open free of charge to current REEF surveyors who are actively conducting surveys and interested in advancing their REEF experience level. Ten active REEF surveyors recently participated in the first such opportunity - survey dives at two new REEF sites in the San Juan Islands, Washington earlier this month. In addition to conducting REEF surveys. The great news is that everyone on the trip who was eligible to move up one experience level did so! A big congratulations goes to Pete Naylor and Mary Jo Adamas, REEF's newest Pacific Advanced Assessment Team Level 5 members, and the rest of the gang who successfully passed the Level 2 or Level 3 exam.
We greatly appreciate the funding support of The Russell Family Foundation. This project will enable REEF to actively engage divers in marine conservation through support and enhancement of the REEF Volunteer Survey Project in the Pacific Northwest. Traditionally, divers and snorkelers have not received much more than a cursory introduction to underwater ecology or marine life identification. Even after years of experience in the water, most divers are able to identify only a handful of the marine life they see during their dives. REEF introduces marine enthusiasts to the incredible diversity of fishes and other wildlife found in local waters as well as the identification resources and survey methods needed to document these species. Active REEF surveyors advance through five experience levels (Novice: 1-3 and Expert: 4-5), based on the number of surveys completed and passing scores on comprehensive identification exams. While 536 volunteers have conducted surveys in the Pacific Northwest as part of the REEF Fish Survey Project, there are currently only twenty-eight members rated as Expert surveyors. However, expert level volunteers have conducted approximately one-third of all surveys submitted to date. It is clear that as volunteers improve their skills, they are more likely to stay actively involved in data collection.
Happy 2008! REEF is looking forward to a great year for marine life everywhere as 2008 has been designated the International Year of the Reef by the International Coral Reef Institute. In this first editon of REEF in Brief 2008, learn about recently completed biological monitoring at the M/V Wellwood restoration site in Key Largo, Florida, a proposed research only site at Gray's Reef National Marine Sanctuary in Georgia and a host of upcoming REEF Field Surveys to tempt your travel bug. Also read about an upcoming dinner and auction to benefit REEF in its hometown Key Largo and meet new office manager, Bonnie Greenberg. Finally, REEF remembers long time member and friend, Chile Ridley, who will be remembered for his generosity to the marine environment.
Best fishes for a healthy, happy start to the new year,
REEF is pleased to welcome Stephanie Roach from Camp Hill, PA as the 2008 REEF Summer Intern and Great Annual Fish Count Coordinator (GAFC). Her internship is supported by the Our World Underwater Scholarship Society. The REEF internship program provides college age juniors, seniors and graduate students the opportunity to experience working at a nonprofit environmental organization. REEF interns assist REEF staff with education, outreach and a multitude of programming. Many REEF interns move on to successful careers in conservation and the marine environment, including natural resource agencies, academics and conservation non-profits (including REEF). In fact, REEF Director of Science, Christy Pattengill-Semmens, Ph.D., is a former REEF intern.
The Our World-Underwater Scholarship Society is a nonprofit, educational organization whose mission is to promote educational activities associated with the underwater world. For over 35 years, they have fostered the development of future leaders of the marine environment through their scholarship and internship programs.
Stephanie graduated this May from Denison University with a Bachelor of Arts in Biology as well as Studio Art. She attended the Skidmore College Summer Six Art Program and the School for Field Studies in the Turks and Caicos where she experienced open water research. By the end of her time in the British West Indies she said, "I realized I wanted to work toward a better understanding of the world's oceans and eco-systems."
As this year's summer intern, Stephanie will act as the primary GAFC coordinator for REEF, along with assisting staff with various activities and preparing and presenting REEF talks and fish ID classes to the Florida Keys community. She will also have an opportunity to present and implement a project which aligns with her interests in combination with REEF needs and activities. She begins her internship June 2 and you can greet her with a happy hello by sending an email to email@example.com or call 305-852-0030 ext. 1#.

Members of the REEF Pacific Northwest Advanced Assessment Team (AAT) recently conducted the 6th annual survey of the Olympic Coast National Marine Sanctuary (OCNMS) near Neah Bay, Washington. Porthole Dive Charters transported the 8 member dive team to ten sites over the course of a week. A total of 89 surveys were completed and the team documented 85 species of fish and invertebrates, including many unusual sightings such as the tubenose poacher, lobefin snailfish, and rosylip sculpin.
The OCNMS covers over 3,300 square miles of ocean off Washington State's rugged and rocky Olympic Peninsula coastline. Sanctuary waters host abundant marine life. A small but important stretch of coastline along the Strait of Juan de Fuca features some of the best diving in Washington State, yet is rarely visited because of the remote location and limited diving facilities. In 2003, REEF started conducting annual assessments at a set of key sites in the northern portion of the OCNMS in order to generate a baseline of data that can be used to evaluate the status and trends of marine communities.
To date, REEF volunteers have conducted 353 surveys in the OCNMS (290 hours of observation time!) and have documented 61 species of fish and 31 invertebrates. The 2008 project summary data is posted here. REEF staff are currently preparing a summary report for the Sanctuary based on the data collected to date.
Funding and support for this year's OCNMS project was generously provided by the National Marine Sanctuary Program, the Seattle Biotech Legacy Foundation, the Winter's Summer Inn in Seiku, and the REEF survey participants. A bunch of spectacular photos have been posted (from both above and below the water) by the team participants. Online galleries include: Janna Nichols, Pete Naylor, April Theod, Ron Theod, and David Jennings.
