It appears that the URL I gave in my message for the endangered species petition
for bumphead parrotfish was incorrect.  I have a new URL that should work:


Failing that, just go to www.wildearthguardians.org, go to the left where it
says BioBlitz and click on "view all BioBlitz featured so far" and then find
bumpheads on the list and click on "requests protection".

Sorry for the inconvenience,  Doug

> I just found out that an NGO (Wildearth Guardians) in the U.S. has

> As I understand it, National Marine Fisheries Service (NMFS), a part of

> Bumphead Parrotfish along with other large reef fish such as Humphead Wrasse

> biomass of near-pristine reefs.  Removing such a huge portion of the natural
> ecosystem carries with it the risk of unknown future consequences, much as 
> the removal of herbivores had on Caribbean reefs.  Removal of large 
> predators on land and in water often sets off trophic cascades with 
> unpredicted major effects.  Because of hysteresis effects in phase shifts, 
> the vulnerability to damage may not be apparent until the phase shift has 
> happened, and trying to reverse the phase shift may be difficult or next to 
> impossible due to the hysteresis.  Is it wise for most most coral reefs 
> around the world to be missing their large fish and half or more of their 
> fish biomass??
