Lad Akins, REEF Director of Special Projects, recently co-authored a paper summarizing work documenting feeding patterns of lionfish in the Bahamas. Understanding the predation behavior of this invasive species is important to be able to predict and mitigate the effects of Indo-Pacific lionfish (Pterois volitans) on Caribbean fish communities. Lad and his colleagues at Simon Frasier University studied the activity levels and prey consumption rates of lionfish on 12 shallow coral reefs in the Bahamas in relation to time of day and prey availability. Lionfish predation rates and activity levels were significantly higher during crepuscular (dawn and dusk) periods than at mid-day. Available prey fish biomass was highest at dawn but lower at mid-day and dusk, suggesting that lionfish predation activity is not limited by prey availability alone. The calculated average daily prey consumption rates was ~3 times the estimates obtained from studies of captive lionfish in their native range and of invasive lionfish observed only during the day. These results will help to predict more accurately the effect of predation by invasive lionfish on native reef fish communities. The study was published in the scientific journal Marine Ecology Progress Series, Vol. 433. A summary of this and all other scientific publications that have included REEF data and programs are given on the Publications Resources page, at http://www.reef.org/db/publications.

This month we highlight Rick Long. Rick joined REEF in 1997 and has conducted 469 surveys, making him one of Hawaii's top surveyors. Mike is a member of the Hawaii REEF Advanced Assessment Team and he lives on Maui. Here's what he had to say about REEF:
How did you first get involved with REEF?
I did my first REEF survey while diving in the Florida Keys and went inactive until I moved to Maui and joined the fish count at the Hawaiian Islands Humpback Whale National Marine Sanctuary. I learned the Hawaiian reef fish by participating in the monthly activities of a local REEF group called Fish Identification Network (FIN) and by volunteering at the Maui Ocean Center aquarium. I learned even more about fish behavior and corals by volunteering with the Herbivore project at Kahekili Beach, doing Reef Check surveys, and with Eyes of the Reef monitoring for coral bleaching and disease. Volunteering in all of these venues, I have learned not only the common names, but also some of the scientific and Hawaiian names of fish and other marine life. I am an enthusiastic advocate for Citizen Science.
In addition to surveying, what other ways are you involved with REEF?
Through the years, I have participated in monthly REEF survey shore dives organized by FIN and other groups. I have also taught Coral Reef slide shows at the NOAA whale sanctuary in Kihei that includes tips for visitors wanting to get in the ocean to see the beautiful fish and coral reefs in our state.
What is your favorite dive spot and favorite fish?
My friends are just as enthusiastic as I am, and can paddle outrigger canoes, scuba dive, or snorkel almost every day of the week in Maui. My favorite coral reef to survey is Maonakala, located within the marine protected area of the ʻĀhihi-Kīnaʻu Natural Area Reserve, and is one of the few coral reefs not in decline. One of my all time favorite fish is a special little chub or rudderfish that lives on this reef. The Hawaiians had a name for the Pacific Gray Chub (Kyphosus sandwicensis) in a yellow morph coloration and they called it the “Queen Nenue” (nay-new-ay).

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. For more information, please contact Leda Cunningham: Leda@REEF.org.
In addition to attending the 11th ICRS, REEF also hosted one of the conference Field Trips. REEF and Horizon Divers hosted 14 participants from various locations around the world including Australia, Japan, Kenya, and several U.S. institutions. Dr. Jim Bohnsack, NOAA Research Fisheries Biologist and Science Advisor to the REEF Board of Trustees, gave a workshop presentation on applying REEF fish survey data towards Florida Keys National Marine Sanctuary management decisions and Paul Humann, renowned marine life photographer and author, taught fish and invertebrate identification classes. Lad Akins, REEF Special Projects Director, gave an overview of REEF and our programs along with a detailed update on what he and REEF partners are working on with the Lionfish (Pterois volitans) invasion in Florida, the Bahamas and Caribbean islands. Participants also had the opportunity to conduct 6 REEF survey SCUBA dives out on our local reefs to get a sense of how Roving Diver survey data are collected.
The survey data our members collect fall into two general categories.The first is the Volunteer Survey Project category that includes all of our Field Surveys and individual members surveying efforts conducted while diving or snorkeling wherever they live or travel to on vacation. The second type of data collected by our surveyors are from our monitoring and research programs in partnership with NOAA sanctuaries, the National Park service, and regional NGO’s and other non-profits as well as various universities. It was this second category of data that our ICRS Field Trip focused on for classroom discussions. REEF data are used by resource managers include artificial reef monitoring, restoration site monitoring, marine protected area assessments, and invasive species collections and fish surveys to name a few. One message that ICRS brought home to all attendees is that now more than ever, there is a critical need for coral reef related research, including studies addressing fish assemblages. There is also a critical need for scientists and policy makers to communicate their research and conservation strategies to the general public, conveying the message about just how vulnerable coral reefs are to anthropogenic disturbances and their importance to our collective well being. REEF will continue our efforts to engage our membership in worthwhile conservation projects that address tropical and temperate fish assemblages.

Check out the latest news in the lionfish invasion. - There's so much going on with REEF's lionfish research and outreach programs, we can't possibly report it all here. Check out the Lionfish in the Media page to see how the media is covering our efforts.
Online data entry available in all regions. - As we reported in last month's REEF-in-Brief, REEF surveyors in ALL regions can now submit their data online. We greatly encourage everyone to enter their surveys online rather than use the paper scanforms, if possible. And remember -- if you conduct a survey at a site that is not yet in REEF's Zone Code database, send us an email (firstname.lastname@example.org) with the site name and latitude/longitude of the site and we will create the code for you. The 8-digit zone code must be in the system before you can enter data from the site.
