Climate change is expected to cause a poleward shift of many temperate species, however, a better understanding of how temperature and species' life histories interact to produce observed adult range is often lacking. REEF data were featured in a new publication on this topic in the scientific publication, Journal of Experimental Marine Biology and Ecology. The publication's authors evaluated the hypothesis that juvenile thermal tolerance determines northern range in gray snapper (Lutjanus griseus), a species commonly caught as juveniles along the US Atlantic coast well north of their adult distribution, using a combined laboratory, field, and modeling approach. To evaluate the relationship between juvenile thermal tolerance criteria and adult distributions, the authors used the REEF database to quantify adult distribution. There was a strong correspondence between observations of adult gray snapper from the REEF database vs. latitude of the predicted survival of juveniles vs. latitude from their modeling analysis. The agreement between the laboratory-derived thermal tolerance measures, the spatial distribution of winter temperature, and the distribution of adult gray snapper support the hypothesis that the adult range of gray snapper is largely limited by the overwinter survival of juveniles. The authors stated that "understanding the interaction between physiology and range is important for forecasting the impacts of climate change on other species of fish where juvenile tolerances are critical in determining range, particularly in seasonal systems". The abstract of the paper and supporting figures can be viewed online here. Visit the REEF Publications page to see all of the scientific publications that have featured REEF data.

Make your plans soon - hotel room blocks are filling up and dive boat space blocks are expiring soon. Complete details can be found online at: www.REEF.org/REEFFest2013
All REEF Fest events are open to the public, but pre-registration is requested for social events and workshops. Register using this online form. Tickets are required for the Saturday Dinner Cruise celebration. Purchase dinner cruise tickets online here. A quick look at the schedule can be seen here. Questions? Please send us an email at REEFHQ@REEF.org or call us at 305-852-0030. We look forward to seeing you all in August!
Why the celebration? In the summer of 1993, a group of pioneering volunteers conducted the first REEF fish surveys. Twenty years later, the Volunteer Survey Project and other REEF initiatives are leading the way as innovative and effective marine conservation programs. You are invited to join us this summer to celebrate 20 years of success.
Our 2014 Fishinar schedule is off to a great start! We've got lots of exciting, fun, and educational REEF Fishinars in store for you this year - featuring your favorite instructors and special guests alike.
Here's a quick glimpse at our upcoming topics:
REEF Fishinars are online webinars that you can view from your computer or iPad from the comfort of your own home. You don't even need a microphone or a webcam to participate - it's easy to participate!
REEF Fishinars are a free benefit of REEF membership, and did you know that REEF members can also access and view any of our archived Fishinars from previous years? A great way for new fish surveyors to learn, or for experienced fish surveyors to brush up on their ID skills.

Next time you sign up for one of REEF’s Field Survey Trips, you’ll be greeted by a new voice. REEF has added a new member to the team; welcoming Jamie Dietrich as the new Trips Program and Communications Manager! As Jamie’s position title implies, her main responsibilities revolve around managing REEF’s Field Survey Trips Program. Each year, REEF leads 10-15 week long international Field Survey Trips to diving destinations across the world. Led by marine life experts, participants learn about the ocean while contributing to marine conservation as citizen scientists. Anyone can join REEF and likeminded divers for an itinerary of diving, seminars and fun! Jamie will also be managing communications and marketing efforts for all of REEF’s programs.
Jamie is a midwesterner at heart, but comes to the Keys from the Big Apple where she spent eight years after university working in Experiential Marketing; listing several Fortune 500 companies among her clients. These days, her clientele seem a bit fishy, as she’s traded in the boardroom and business suit for the beach and a wetsuit. Jamie recently became a certified Divemaster and Coral Reef Research Diver, and she spent the majority of the last year developing her conservation expertise on a volunteer marine mission in Fiji. After leaving her island home and returning to the States, she decided to make “island-time” a permanent staple in her life by relocating to the dive capital of the world. Jamie is excited to get her feet wet and continue to contribute towards meaningful work that aids in the protection of what she’s come to love most, the ocean.
We have just the thing for after the holiday rush is over -- free, educational REEF Fishinars. These hour-long sessions let you learn and have fun from the comfort of your living room. Check out the full schedule at www.REEF.org/fishinars. And keep an eye on that space because we will be adding new ones for 2015 soon. On the schedule so far....
Explore our Fishinar webpage, register for the sessions you like, and we'll see you online! No special software or microphone is required - just a computer with speakers and an internet connection. And did we mention they are FREE to REEF members!
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 research group at Palm Beach State College is using REEF data on South Florida fish assemblages to evaluate beach renourishment projects.
- Researchers from NOAA's Biogeography office are including REEF data in the development of a management plan for the marine portion of the NE Ecological Corridor Reserves in NE Puerto Rico and Culebra Island.
- Researchers at Bimini Biological Field Station are using REEF sightings of two endangered sawfish species to better understand the species' current distribution and status.
A complete list of scientific publications featuring REEF programs and data can be found at www.REEF.org/db/publications.
Scientists and volunteers from REEF, and our partners at Scripps Institution of Oceanography and Cayman Islands Department of the Environment, are gearing up for the annual Grouper Moon Project next month. Scientists will be on the ground and in the water during the full moon in January. Since 2002, the group has conducted ground-breaking research to study the Nassau Grouper spawning aggregations, to help ensure recovery of the populations of this iconic species. This year, the team will be collaborating on new work using cutting-edge technology including underwater microscopes to evaluate larvae in-situ. We will also be hosting several live-feed videos through Google Hangouts as part of REEF’s Grouper Education Program. In 2011, with funding from Disney Conservation Fund, REEF launched the education program to engage Caymanian students in the project. This exciting initiative brings the Nassau Grouper into elementary and high school classrooms through lesson plans and the Hangouts that connect classrooms with scientists in the field. We will post Hangout details on our Facebook page and www.REEF.org/groupermoonproject in a few weeks.
Six volunteer divers from the REEF Advanced Assessment Team (AAT) surveyed two sites off the Aquarius Reef Base in Key Largo, Florida, to assist the National Marine Sanctuaries Program (NMSP) with the science component of the Aquarius 2007 Mission: If Reefs Could Talk. Aquarius, the world's only undersea laboratory, is part of NOAA's National Undersea Research Program (NURP) and sits seven miles off shore at Conch Reef. A valuable resource and good neighbor to REEF HQ, Aquarius hosts scientists from around the world, from sponge chemists to astronauts, in innovative research and education.
The team included REEF Special Projects Manager Lad Akins and AAT members Dave Grenda, Brian Hufford, Lillian Kenney, Wayne Manning, and Mike Phelan. Twelve fish surveys were conducted at each of two research sites near Aquarius using the Roving Diver Technique (RDT). This year's data will be compared to surveys collected during a 2001 mission to assess change in resident fish populations. The team also assisted NMSP in documenting the occurrence of long-spined sea urchin (Diadema) at each site. Once abundant on Florida Keys coral reefs, herbivorous Diadema play an important role in keeping coral-stifling algae from overtaking the reef structure.
