1. Caulerpa taxifolia conference (Global)
From: Barry Rice (bamrice(at)ucdavis.edu)
(Condensed from the conference web site)
A two-day conference on the non-native invasive marine alga Caulerpa
taxifolia (Mediterranean strain) will be held 31 January-1 February 2002.
The agendum will include discussions of management and education
strategies including 1)ongoing eradication efforts, 2)strategies for
future detection, control, and eradication, 3)education and outreach for
industry and the public, and 4)cooperative agreements between regulatory
agencies and aquarium/aquatic plant industries.
Location: San Diego, California
Cost: $25 students / $75 others.

2. Oriental bittersweet hybridization? (Pennsylvania, USA)
From: Betsy Lyman (blyman(at)tnc.org)
We have been wondering about the possibility of Celastrus orbiculatus
(oriental bittersweet, non-native) and C. scandens (American bittersweet,
native) hybridizing and producing a wayward child, making the planting of
C. scandens not a really desirable alternative in areas where the exotic
is found. According to the TNC Species Management Summary, researchers did create a fertile
hybrid in a controlled breeding experiment. Other researchers found some
specimens that they thought MIGHT be hybrids. The TNC Species Management Summary was written in
1994--any new news on this?

3. Fire ants expanding range (California, USA)
From: Barry Rice (bamrice(at)ucdavis.edu)
Red imported fire ants (RIFA) are widely established in the southeastern
USA, with smaller populations in New Mexico, Arizona, and Nevada; now they
are expanding their range in California. They have been found in southern
California and the San Joaquin Valley. Just recently, however, they have
been found as far north as Sacramento County. Read about it in this press
release: http://www.cdfa.ca.gov/phpps/pdep/rifa/Sactoants.pdf
The California Dept. of Food and Agriculture RIFA web site is excellent
(http://www.cdfa.ca.gov/phpps/pdep/rifa/index.htm)
I recommend in particular the animated map showing RIFA's USA invasion:

4. Noxious weeds class (Colorado, USA)
From: Barry Rice (bamrice(at)ucdavis.edu)
Celestine Duncan emailed regarding weed classes to be held in Loveland,
Colorado, in April-May 2002:
"The Western Society of Weed Science has sponsored the course since 1990.
It is one of the few courses taught in a workshop (hands-on) format. We
grow about 28 different weeds in the greenhouse for identification, and
workshops include weed identification, biological control, herbicide mode
of action, herbicide formulations, aquatic weeds, calibration (horse,
backpack, etc), and weed management planning. An interactive lecture
format is used for weed ecology, biology, and management and inventory
techniques."
