Abstract
Anthropogenic
activities
have
led
to
a
global
rise
in
water
temperatures,
leading
an
increased
interest
how
warming
affects
infectious
disease
ecology.
While
most
studies
focused
on
individual
host-parasite
systems,
there
is
gap
understanding
the
impact
of
multi-host,
multi-parasite
assemblages
natural
ecosystems.
To
address
this
gap,
we
examined
freshwater
eukaryotic
parasite
communities
ten
lakes
near
Konin,
Poland:
five
artificially
heated
and
nearby
non-heated
“control”
lakes.
Since
1958,
experienced
mean
annual
temperature
increase
2°C
due
hot
discharge
from
two
adjacent
power
plants.
We
collected
seasonal
environmental
DNA
(eDNA)
samples
surface
waters
over
two-year
period
applied
targeted
metabarcoding
compare
richness
distribution
parasites
across
lake
types,
with
focus
protists
fungi.
Using
literature
searches
sequence
metadata
GenBank,
identified
putative
which
included
Alveolates,
Stramenopiles,
basal
Fungi
Ichthyosporeans,
as
well
their
associated
hosts.
Heated
exhibited
distinct
assemblages,
higher
parasitic
chytrids
aphelids
particularly
during
summer,
suggesting
thermal
preferences
among
some
species.
A
general
linear
model
suggests
that
chytrid
may
be
partly
green
algal,
diatom-
dinoflagellate
These
findings
highlight
can
drive
shifts
potentially
altering
dynamics
