Resumen:
Lake Orta experienced for a few decades a unique history of chronic
pollution, with extreme changes in pH and copper concentration.
Currently, the lake has recovered to its almost pristine oligotrophic
conditions, but its sediments still preserve the record of all the
changes that happened since the establishment of the first polluting
factories in the 1920s, through to the liming activities in 19891990,
and to the recovery phase that is still going on. Here we review the
current knowledge for Lake Orta regarding rotifers, a diverse component
of the zooplankton of the lake, through studies on living organisms and
on their resting stages accumulated in the sediments. We also report a
brief review of what is known in general on the effects of changes in pH
and copper concentration on rotifers at the population, species and
community level, providing expectations for such effects on the rotifers
of Lake Orta. Then, we conclude our review with a perspective on the
potential use of rotifers hatched from the resting stages in the
sediment of Lake Orta with the description of experiments that can be
performed in the future in the framework of resurrection ecology, in
order to understand the mechanisms of past and future changes in the
environment.
