   About D. antillarum diet:

   In the mexican reefs were D. antillarum is recovering the presence of
   the urchin and the apparent scarcity of fleshy and calcareous
   macroalgae is evident; one thing that called my attention is
   that filamentous algae don`t seem to be very palatable to the urchin
   as they are abundant even when D. antillarum is present in large
   numbers (Jordán-Garza et al 2008 Coral Reefs V27 N2 p295). I have seen
   some contrasting reports about the diet of Diadema for example Randall
   et al 1964 Carib.J.Sci. 4(2&3) p421-433) in a very interesting
   pre-dieoff report find that Diadema will eat the available plants
   (from seagrass to macroalgae) in their location and even detritus
   mixed with sediments; also the Diadema workshop 2004 (Nature
   Conservancy) mentions that D. antillarum is relatively non-selective;
   but other reports from laboratory experiments do show some dietary
   preferences (Solandt and Campbell 2001, Car. Jour. Sci. Vol. 37 N3-4,
   p.227-238) and I think there are other reports from the eastern
   Atlantic. Hope this helps...

Can anyone alert me to papers published on the specific diet of D.a? Has anyone
watched them eat the same species of alga over time? I think these lawn keepers
have a specific palate??

Quoting John Ware <jware at erols.com>:

* Drew and Dan,
* Well, since I didn't see any other replies:
* D.a. are typically sparse, altough I understand there is a comeback at
* DBML.  What we have done in the past is to lay out a transect line using
* a 50 m tape.  We laid our tapes along depth contours in order to
* determine a depth effect.  Then two divers swim along the line, one on
* each side, with a 1 m pvc pipe.  Each diver counts the number of D.a.
* within 1 m of the tape using the pvc pipe as a guide, thus surveying 100
* m**2.   This is simple and fast.
* Sounds like you may be taking people without much diving experience and
* maybe even less night diving experience.  D.a. are very good at hiding,
* so all surveys should be done after the sun goes down.  Without good
* buoyancy control, there could be some close encounters with the D.a.
* which, believe me, are VERY painful.  Do some research on first aid and
* take along the required stuff - DBML may help you there.

Update of the Eritrea Coastal Marine Island Biodiversity Project (funded by
GEF, implemented by UNDP, anchored in the Ministry of Fisheries) by Dr Alain
Jeudy de Grissac.


Summary of activities January 2005 - December 2007


In reference to the coral list discussion stating a lack of activities and in
particular of knowledge on corals since the 90s, there has been a growing
pressure by the present actors on myself, Alain Jeudy de Grissac, acting as TA
for the ECMIB project during the period 2005-2007, to clarify the present state
of the corals in Eritrea and report on biodiversity surveys, activities and
research that have been achieved during this period. 


During these three years, none of the persons initially involved in the coral
list discussions debating on the state of the corals in Eritrea, have had any
contact with the project management or were involved in the project activities
except Dr. Stefan Howe (one of the main assets of the project with in
particular the training of more than 40 Eritrean nationals to marine and
coastal ecology). The others were out of the country with no contact with the
project and therefore no insight information on what was happening in Eritrea. 


Charlie Veron was invited for a survey and training mission, unfortunately able
to join during the final stage of project (October November 2007), and the
results are coming out only now. Thanks to Charlie, the fantastic results from
the mission are now bringing some focus on the country and I hope some funding
as there is an important need of support for this young country.


The project started in 1999 and due to different problems, has had three
technical assistants, Dr. Peter Raines who has left after 11 months due to the
conflict with Ethiopia, Dr. Jeremy Kemp for less than two years who has left in
2004 for personal reasons and myself from 2005 to 2007. A mid-term evaluation
conducted end 2003 recommended to close the project but the Government of
Eritrea asked for continuation.


For capacity building, from 2005 to 2007, the following scientists were
involved in the project: Dr. Michael Pearson for ICAM, Dr. Andrew Price for
general marine ecology, Dr. Virginie Tilot for coral reefs, Dr. Rebecca Klaus
for GIS, Dr. Nicholas Pilcher for marine turtles, Khaled Allam for Protected
Areas and Dr Charlie Veron for coral reefs. The total input of all these
experts and some others was about 500 days over the three years. 


At my arrival in 2005, four UN volunteers were involved in the project and were
progressively replaced by competent national. Selected national (53) were sent
abroad for training during the same period corresponding to about 600 days.
Most of them were participating in field missions and during the same period
participated for about 4000 field days collecting biodiversity data on marine
turtles, dugong, coral reefs, mangroves, seagrasses, algae, birds and
socio-economic data on the coastal villages. 


For the coral reefs, 96 stations have been studied of which 68 using reef
check, 16 permanent stations by using video and photo transects, photo quadrats
and 12 visited during the coral taxonomy mission. Information on the reef check
data could be available from the coral reef team from the Ministry of Fisheries
in Massawa as soon as data are analysed. More information on the training,
exploratory missions and coral surveys by video and photo could also be
obtained from Dr. Virginie Tilot (v.tilot at wanadoo.fr).


For coral reefs, before the visit of Charlie Veron, the existing records were
of 154 species. The mission was organised in order to visit the northern Dahlak
islands (Isratu, Dahret, Tanam, Enta?edell, Durghella), the southern Dahlak
islands (Gulf of Zula, Dissei, Madote, Shumma) and Assab islands near Bab El
Mandeb (Sanahor, Musa?af , Abeilat) where the waters are deeper and the coral
cover can reach 100%. The records are now 220 species from 38 genera with 5 new
species under description and perhaps one new genus. During a lecture in the
capital Asmara for all national authorities with the attendance of the
Ministries of Tourism and Fisheries, Dr. Veron presented the major results,
including comments on the limited bleaching and on the resilience of Eritrean
corals to high water temperature (during some dives in August, the water
temperature reached 37.5 Celsius at 10m depth!). 


More information on all the activities of the project can be found on the
project initiated website www.eritrearedsea.org and each national responsible
expert can be contacted through the website. At my departure, the state of the
coast of Eritrea was in the print house and the fina GEF evaluation will be
soon on line as well as the final project report.


For people interested to visit Eritrea, please note that you will not be able
to collect data in the Eritrean Red Sea waters, including on coral reefs,
unless you have the authorisation of the Ministry of Fisheries.


Being involved in other programmes, I remain available for any information on
Eritrea biodiversity and contacts with scientists participating in the project
or for access to the country at the following Email: alainjeudyde at hotmail.com

Dear listers:

During a recent dive?(75-80 ft deep) in the north coast of Puerto Rico I found
out?numerous Xetospongia muta totally or partially broken.??Some sponges broke
flush to the substrate, others broke in different angle when compared to the
next standing; there was not a clear break pattern.??On March 20-22, Puerto
Rico and the USVI coasts received the impact of a powerful cold front?which
produced 30-plus feet breaking waves causing significant coastal erosion.?
Could it be possble that soft or weak areas of large high profile?X. muta did
not resisted?such continuous?high energy swell/surge?

I will appreciate any comments or references.

A few places are available in the course "Diseases of Corals and Other 
Reef Organisms" to be held August 9-17 at Mote Marine Laboratory's 
Tropical Research Laboratory on Summerland Key, Florida (go to 
http://isurus.mote.org/Keys/adv_courses_2008.phtml for information and 
application form).  Contact Esther Peters (epeters2 at gmu.edu) if you have 
questions about the course, Lauren Waters 
(Lauren.Waters at Delta-Seven.com) for registration questions, or Erich 
Bartels (ebartels at mote.org) for questions about the diving program.

At this time the Coral Tissue Slide Reading Workshop has been filled, 
but contact Dr. Peters if you might be able to participate in it this 
summer, in case space becomes available.

Sounds good! Recent improvements in web technology means that an electronic
only journal website could be setup relatively cheaply and easily. Many of the
traditional mangement tasks associated with submission, review and publishing
could be automated so that the overheads could be quite low and easily recouped
by a very small fee for subscription or downloading an article.  The main issue
I think would be getting acceptance - a group of high profile researchers would
need to get behind the idea by submitting and reviewing articles or being on th
editorial panel. 
It would be good to give all researchers free or almost free access - for
example many independent researchers or those in small institutions or 
developing countries cannot afford the costs associated with journal
subscription. I think that the current web technology would allow this.

Subject: [Coral-List] Some more on Springers Open Access Policy

Hi there Dear listers: Out of a little boldness and some encouragment I want to
say that, Springers open access policy is actually a Non Open Access Policy.
Consequently, I wonder if its not time or is it not proper to have a similar
joint effort, just the same as the one that has sustained well, alive, and
productive the coral list (not just due to NOAA?s continued and great support),
but also from all of you out there, in order to publish an open access journal
on Coral Reefs with the same or higher standards as Springer?s current Coral
Reef publication. I accept Springers Policy based upon what it is for them a
sound business decision,  nevertheless I have an intuition that probably the
time is right for at least one new player to enter the Coral Reef Knowledge
market most surely at reduced marginal costs and profiting not just the journal
but also the readers and above all the authors... It is simply, sound and fair
