Abstract
A recent chironomid record of three shallow, high
altitude lakes in southern Tibet, as well as a short
palaeolimnological history of one lake, are presented.
The recent chironomid assemblages consisted
of 13 taxa; one of the Orthocladiinae taxa
recorded most likely represents a new species. In
spite of the low head capsule concentration in the
sediment core of Lake Karuugema, probably due
to physical disturbance, redistribution and outwash
of head capsules, there was a trend from assemblages
composed of stenothermal/rheophilic
taxa to eurythermal/limnophilic taxa. This shift
in assemblage structure suggests that changes in
monsoon precipitation and catchment hydrology
may have influenced the habitat conditions of the
chironomids.
