Abstract The effects of climate change on oligotrophic rivers and their communities are almost unknown, albeit these ecosystems are the primary habitat of the critically endangered freshwater pearl mussel and its host fishes, salmonids. The distribut

The thick-shelled river mussel, Unio crassus (Bivalvia: Unionoida), is one of Europe's most-threatened mussels. Finnish populations of U. crassus lie close to the northern limit of its natural distribution. Extirpation of these populations will reduc

A growing body of literature is using sclerochronological information to infer past climates. Sclerochronologies are based on series of skeletal growth records of molluscs that have been correctly aligned in time. Incremental series are obtained from

Sclerochronology and dendrochronology are based on series of incremental skeletal and cambial growths that have been correctly aligned in time via cross-dating (i.e., incremental dating through synchronization of the growth variability on a visual an

The colour polymorphism of Cepaea hortensis (Muller) (Gastropoda, Helicidae) was investigated in peripheral populations in five geographical regions in Finland. Yellow-shelled individuals were found in all the regions, pinks in two and browns in none

This study bridges two conchological approaches to model the growth characteristics of freshwater pearl mussel shell: size-at-age and sclerochronology. We demonstrate a simple numerical model that transfers sclerochronological data into realistic est
