“…Because mollusks' relation to their paleohabitat can be extrapolated from the ecology of contemporary species, the ecological conditions of past geological epochs can be inferred from fossil shells (Leonard-Pingel et al, 2012, Yanes, 2012. The shells themselves have been used as environmental archives, and they also contain metabolic signals (Mutvei &Westermark, 2001;Geist et al, 2005a). Due to the dietary and cultural role of mollusks, shells can be used in archeology to assess the character of habitats exploited by ancient humans (Morey & Crothers, 1998).…”

We studied shell variation in the thickshelled river mussel (Unio crassus Philipson, 1788) sampled from two sites of very different character: (1) a rocky channel (San river) and (2) a fine-sediment channel (Zborowianka river). The analyzed mussels differed significantly between the sampled channels in almost all analyzed phenotypic traits and shape indices. Intersexual variation was so low that it cannot be used effectively for sexing in this species. The growth rate was much higher in the fine-sediment and nutrient-rich channel than in the rocky one, but the asymptotic shell length for the rocky channel was larger than for the fine-sediment channel, suggesting higher survival in the mountainous, unmodified river. Shell size differed significantly within the rocky channel, depending on microhabitat: shell size and dorsal arching were much greater in mussels living in the strong current of the rocky midchannel than in those inhabiting still water at the nearest bank. The results demonstrate that microhabitat conditions significantly determine shell shape.

“…For example, the ocean quahog, Arctica islandica (linnaeuS, 1767), lives for more than 500 years (JoneS, 1983;ropeS & MurawSki, 1983;Schöne, FieBig, & others, 2005;wanaMaker, ScourSe, & others 2008;BuTler & others, 2011), Neopycnodonte zibrowii wiSShak & others, 2009, for more than 545 years (wiSShak & others, 2009), and the European freshwater pearl mussel, Margaritifera margaritifera (linnaeuS, 1758), exceeds a lifespan of 200 years (MuTvei & weSTerMark, 2001). Each specimen of such long-lived species opens a multi-century window into the climatic past.…”

“…In conclusion, it has been proven in many papers (Clark 1975;Hall 1975;Whyte 1975;Mutvei and Westermark 2001;Goodwin et al 2001) that the lines on the shell surface are related to cycles. Nevertheless, prism width distribution has been demonstrated to be a random variable following a gamma distribution.…”

A study of the distribution of the prism width inside the prismatic layer of Unio tumidus (Philipsson 1788, Diss Hist-Nat, Berling, Lundae) from Lake Neuchâ-tel, Switzerland, has been conducted in order to determine whether or not this distribution is random. Measurements of 954 to 1,343 prism widths (depending on shell sample) have been made using a scanning electron microscope in backscattered electron mode. A white noise test has been applied to the distribution of prism sizes (i.e. width). It shows that there is no temporal cycle that could potentially influence their formation and growth. These results suggest that prism widths are randomly distributed, and related neither to external rings nor to environmental constraints.
