I may be in the minority, but I doubt it. As a graduate student, I am
amazed and at times overwhelmed by the general wealth and utility afforded
by permanent collections, even a modest one. The person-hours that make
collections permanent are immense; decades and careers have been spent to
construct a lasting legacy of knowable biodiversity. Students should but
don't need to travel thousands of kilometers when all they need do is
pluck a hair from a mount here, or clip .1 mg of plant tissue there,
return and begin genetic analyses.
Collections represent genetic archives, just as the living organisms do.
To question the value of a collection is to question the value of
biodiversity itself. Let's hope the molecular generation has the same
amount of foresight to permanently preserve the whole genomic DNA
extractions from all types of samples. These samples need as much
curation and archivability as do organismal collections.
