Apologies for cross-mailing!

Dear colleagues,

We would like to draw your attention to a session on environmental
biomonitoring held at the Climate and Fisheries conference (Impacts,
Uncertainty and Responses of Ecosystems and Communities) in Victoria, BC,
Canada from 26-28 October 2005. The session is entitled "Innovative
biomonitoring techniques for aquatic ecosystems". For a brief description of
the session objectives see below. Additional information on the meeting may
be obtained here:

We would like to encourage you to attend the conference and submit an
abstract for our session. Direct your abstract to the following email
address and refer to the session title below: [log in to unmask] (Program
Chair, Mark Johannes).

We look forward to meeting you in Victoria, BC.

Please spread the word to people that might be interested in joining the
session. Thank you!

Best regards

Bernd Schöne
Nick A. Page

Important dates:

Deadline for abstract submissions: 31 August 2005
Deadline for early bird registration: 15 September 2005
Deadline for reduced accommodation rates: 25 September 2005

Critical assessment of the effect of human-induced environmental and climate
changes on aquatic ecosystems requires long-term and high-resolution records
of past conditions and monitoring of the current state. Such data can help
decision makers understand natural variability, define baseline conditions
for biomonitoring, and set targets for restoration.

During recent years, substantial progress has been made in inferring
environmental conditions in marine, freshwater, and terrestrial ecosystems
using tree-rings, shells of bivalve mollusks, fish otoliths, sediments, etc.
For example, periodically grown biogenic hard parts of many organisms
provide valuable source material for multi-proxy environmental and climate
reconstructions. Variations in growth rate and geochemical properties of
biogenic skeletons function as ultra-high resolution, i.e. annually, monthly
and even daily archives of environmental change. These records of previous
environmental conditions indicate that ecosystems are rarely stable but
often respond to cyclic changes in regional climate over time.

This session will bring people of various disciplines together and provide
an overview of new analytical techniques currently available for
environmental hind- and nowcasting in the Pacific Northwest.
