I am slightly suss about the lethality of inbreeding. The Lord Howe Island
Woodhen population was reduced by rat predation to one or two pairs before
breeding up again to fill the Island, presumably any bad genetic combinations
died out . Cheetahs world wide apparently have no genetic variation.
Regents probably survive today because a few were more nomadic than their once
numerous contemporaries, and survived when their habitat was destroyed, passing
on their genes to the few hyper nomads that remain. Early collectors noted so
many RHs in the Upper Hunter around Scone that the volume of their calling
made conversation difficult, That area was I suspect their heartland, it has
now been almost totally cleared.
Habitat destruction has caused the demise of RH's, an indicator of Human
overpopulation, as is Global Warming itself; all the windmills, Solar farms,
hydro projects and even Nuclear Power can only slow the inevitable as the human
population grows and grows.
Political Correctness denies any real debate on Population Control, which is
the only real long term solution, but unfortunately it is too late now.
Depressingly Yours
Michael
