[Taxacom] (Fwd) Dichotomous key software

Greetings,

I have tested a number of interactive keys and have found they frequently
gave wrong answers. So in that respect they seem not to be really to
different than dichotomous keys.

As someone who identifies invertebrates for a living, I can tell you that I
prefer a good, hard copy dichotomous key. I can have it open next to my
microscope, make notes or sketches in the margins as well as add references,
and leave it open to compare directly with other resources, on line or other
wise.

Just my opinions,
Christopher

This is interesting.  I've gotten several replies strongly
recommending that I steer away from paper dichotomous keys and
instead go with interactive keys (Lucid and Delta are most often
mentioned).  It makes me wonder if I'm starting to get old and set in
my ways, that I've missed a recent memo suggesting that interactive
keys are now the standard "industry" format, or that there's a strong
desire to kill less trees (I hope it's the latter and not the
former)...  A little background information on why we want
dichotomous keys might help.

Our campus is officially designated an arboretum and is part of the
Nebraska State Arboretum system.  All biology majors are required to
take an introductory course in botany.  One of the lab activities is
a "tree walk" where students walk about campus and learn how to
identify plants (i.e., trees) in the field.  Hence, the need for a
paper version of a dichotomous key (key is a booklet also given to
visitors to the arboretum).  Next August two other faculty members
and I will take a group of students to the Boundary Waters in
Minnesota for a 5-6 day canoe trip.  One requirement for that class
will be plant identification of plants in the field.

In both cases I cannot imagine how an interactive key would ever be a
viable option.  Lugging a several pound laptop into the field to
identify organisms seems like overkill when a paper version weighing
a few ounces will do just as well.  I guess I need an explanation as
to why there would ever be an emphasis on interactive key software
programs over dichotomous keys?  Most of the identification that I do
is in the field.  Older field guides generally include keys for
identification but the more recently published guides lack them, the
emphasis is instead on full color photos.  Nothing beats a field
guide with line drawings and a good key for identification.

As much as I appreciate technology and the contribution computers
make I find myself being a bit of Luddite when it comes to the idea
of chucking out dichotomous keys.  Taking time to produce a pretty
interactive key seems like a waste of time.  My target audience
already spends too much time in front of a computer.  They need to
grab a backpack, head out into the woods, and sit under a tree while
trying to identify something cool they've just found.  Difficult
groups of organisms being treated in monographs, etc. should continue
to use the old fashioned dichotomous key.  Computer servers go down,
websites change, specialists die, but their paper version keys will
live on for decades.

I better go, I'm feeling like a grumpy old man.

Cheers!

JB
