Resumen:
Given
the
importance
of
ecosystem
services,
it
is
critical
that
we
improve
our
ability
to
identify
and
understand
changes
in
aquatic
ecosystems,
and
translate
them
to
risk
of
service
loss.
Furthermore,
to
inspire
changes
in
human
behavior,
it
is
equally
critical
that
we
learn
to
communicate
risk,
and
pose
risk
mitigation
strategies,
in
a
manner
acceptable
to
a
broad
spectrum
of
stakeholders.
Quantifying
the
nature
and
timing
of
the
risk
is
difficult
because
(1)
we
often
fail
to
understand
the
connection
between
anthropogenic
pressures
and
the
timing
and
extent
of
ecosystem
changes;
and
(2)
the
concept
of
risk
is
inherently
coupled
to
human
perception,
which
generally
differs
with
cultural
and
socio-‐economic
conditions.
In
this
study,
we
endeavor
to
assess
aquatic
ecosystem
risks
across
an
international
array
of
six
study
sites.
The
challenge
is
to
construct
a
methodology
capable
of
capturing
the
marked
biogeographical,
socioeconomic,
and
cultural
differences
among
the
sites,
which
include:
(1)
Muskoka
River
watershed
in
humid
continental
Ontario,
Canada;
(2)
Lower
San
Joaquin
River,
an
impounded
snow-‐fed
river
in
semi-‐arid
Central
California;
(3)
Cienaga
Grande
de
Santa
Marta,
a
tropical
coastal
lagoon
in
Colombia;
(4)
Senguer
River
basin
in
a
semi-‐arid
region
of
Argentina;
(5)
Laguna
de
Rocha
watershed
in
humid
subtropical
Uruguay;
and
(6)
Palomas
Lake
complex
in
oceanic
Chilean
Patagonia.
Results
will
include
a
characterization
of
the
experimental
gradient
over
the
six
sites,
an
overview
of
the
risk
assessment
methodology,
and
preliminary
findings
for
several
of
the
sites.
