THE LAND SNAIL LIMICOLARIA KAMBEUL CHUDEAUI GERMAIN IN THE ETHIOPIAN RIFT VALLEY: HABITAT, ECOLOGY AND SHELL ISOTOPE GEOCHEMISTRY

Abstract

The land snail Limicolaria kambeul chudeaui Germain was collected from the margins of Lake Tilo, a small caldera in the Ethiopian Rift
Valley. Although fossil specimens Of this subspecies have been used in
palaeoclimatic reconstruction, there have been no previous reports of living examples. Here we describe the local habitat, climate and some aspects of ecology and isotopic variation within the snail shell. If isotope data can be obtained for fossil shells. this may provide a high-resolution record of-past seasonal climate variability
