REJMANEK'S PROPOSAL TO SIMPLIFY PHYTOSOCIOLOGICAL NOMENCLATURE
From: Adolf Ceska <aceska@victoria.tc.ca>

The  Code  of  phytosociological  nomenclature  (Barkman  et al.
1986), Article 10, presents  the  rules  for  forming  names  of
associations and other syntaxa (alliances, orders and classes):

"The  name  of  an  association  of a syntaxon of higher rank is
formed from the validly published scientific name(s) of  one  or
two  of the plant species or infraspecific taxa mentioned in the
original diagnosis. This proceeds in such a way that a  definite
termination  indicating  the  rank  is  added to the stem of the
generic name ...
When such a syntaxon is named after two plant taxa then, if they
belong to different genera, the termination which indicates  the
rank  is  appended  to  the stem only; a connecting vowel is ap-
pended to the stem of the first  generic  name  (the  connecting
vowel  may  be missing; see Appendix). When epithets occur, they
must be in the genitive, if they are declinable."

Don't despair! If you cannot understand the English  version  of
the  Code,  read  the German version: it is considered to be the
"decisive" one.

After you sort out all the genitives and connecting vowels  (the
Appendix  to the Code is a great help, but you will still need a
good knowledge of Latin and some Greek), you may  come  up  with
names similar to those used by Peinado et al. [see BEN # 213]:

   Ledo decumbentis-Piceion marianae
      Piceetum glauco-marianae
      Larici laricinae-Piceetum marianae
      Rubo chamaemori-Piceetum marianae
      Boschniakio rossicae-Alnetum crispae

When I showed one European system of community classification to
my  able  assistant,  she  immediately  noticed "Poo compressae-
Tussilaginetum", and I could not convince her that "Poo"  refers
to Poa. She insisted on its more vernacular meaning.

My  friend  Prof.  Marcel  Rejmanek teaches plant ecology at the
University of California in Davis, and  for  several  years  has
been trying to explain the rules of naming plant associations as
described  in  the  Code.  Year  after year, his explanations of
connecting vowels and genitives of nouns and  declinable  adjec-
tives fell on deaf ears.

In  his article Rejmanek (1997) wrote: "Two or three generations
back, it was correct to assume that all people in academia had a
reasonable background in, and passion for,  Latin.  This  is  no
more  a valid assumption. ... in this case strict adherence to a
complicated  Latin  nomenclature  detracts  from  the  otherwise
extremely useful procedures of the Zurich-Montpellier School. It
makes  for  a  sort  of  priesthood which does not encourage its
adoption beyond the circle of chosen people. This is why vegeta-
tion scientists in many  countries  are  inventing  independent,
endemic approaches, often ignoring the Zurich-Montpellier School
entirely."

How  can  we  simplify  phytosociological nomenclature? Rejmanek
(1997) proposes using one or two plain Latin plant  names  (con-
nected  by a dash) and an abbreviation to indicate the rank of a
syntaxon. In order to facilitate meaningful alphabetic  ordering
of  syntaxa,  the name of a dominant species should be the first
one.

The example of system by Peinado et al.  in  this  transcription
would become:

  AL: Picea mariana - Ledum decumbens
      A: Picea glauca - Picea mariana
      A: Picea mariana - Larix laricina
      A: Picea mariana - Rubus chamaemorus
      A: Alnus crispa - Boschniakia rossica

This  form  of  naming  plant associations and other syntaxa has
been actually used in older papers of Zurich-Montpelier  School.
The Code considers them as "orthographic variants" and considers
them  validly  published, but only if they were published before
January 1, 1979. According to the Code, they  have  to  be  cor-
rected to the regular (i.e., more complicated) form.

Rejmanek  gave several examples where authors opted for a simple
combination of Latin names of plant species for  plant  associa-
tions and higher syntaxa. He cited Klinka et al. (1996) [see BEN
#  151] as the best example of this approach. A simple change of
the Code would greatly simplify  phytosociological  nomenclature
and I would not have to argue with Samantha over "Poo" any more.
That example would become

      A: Tussilago farfara - Poa compressa

ENLICHENMENT WORKSHOP III: CLADONIA AND CLADINA
From: Patrick Williston <patrickw@interchange.ubc.ca>

Date: Sept 24-26 1999
Location: Edgewood Blue, Clearwater, British Columbia, Canada
Instructor: Trevor Goward
Cost: $60 CDN
Maximum enrollment: 13

This  is  the  third  in  a  series of workshops in which Trevor
Goward shares his knowledge of lichens.  The  workshops  include
lectures,  laboratory study, and field work, and are intended to
provide participants with a basic working  knowledge  of  lichen
taxonomy,  ecology,  and  indicator  value.  They are held twice
yearly in the Upper Clearwater Valley, near beautiful Wells Gray
Provincial Park.

Participants are encouraged to bring warm clothing,  rain  gear,
sturdy  footwear, a handlens, personal lichen collections, and a
copy of Trevor's latest book "The Lichens of  British  Columbia:
Illustrated  Keys.  Part  II  --  Fruticose Species" - available
after early September from Crown Publications:
http://www.crownpub.bc.ca . Lodges, hotels, B&B's,  and  camping
facilities are available.

From: Jan (Suspa) Leps <suspa@tix.bf.jcu.cz>

Introductory and advanced courses
January 2000, Ceske Budejovice, Czech Republic

We are offering two one-week-long intensive courses for students
and  researchers  interested  in  use  of  ordination methods in
ecological research. On both courses, there is  sufficient  time
for  theory  and  practice, using the CANOCO for Windows version
4.0 package. Check the following URL for more details:
