Abstract Only about a dozen species of animals are known to achieve maximum ages (Amax) exceeding 100 yrs, including the freshwater pearl shell (Margaritifera margaritifera). This species has a life-span of between 100–200 years depending on latitude and environmental conditions. The difference in Amax is 3–7 times when southern populations, with Amax of 28–40 yrs, are compared to northern Arctic populations, with Amax of 114–190 yrs. Evolutionary and ecological explanations for longevity in… 
Masters of Longevity: Lessons from Long-Lived Bivalves – A Mini-Review
A review of the current knowledge of cellular ageing in bivalves with a focus on the antioxidant system, as well as tissue repair and metabolic capacities of extremely long-lived species recommends a focus of future research on the molecular mechanisms potentially involved in supporting longevity in these species.

The great variability in age and growth among and within species shows that allocation to growth is highly plastic in freshwater mussels, and the strong negative relationship between growth and longevity suggests this is an important trade‐off describing widely divergent life‐history strategies.
Growth models and longevity of freshwater pearl mussels (Margaritifera margaritifera) in Spain
The two models were similar in performance and were well fitted (around 99%) to shell-length-at-age data, although the hyperbolic function appears to be applicable only from 6 years of age.
Long-Lived Species of Bivalves Exhibit Low MT-DNA Substitution Rates
A Bayesian Phylogenetic Covariance model of evolution analysis using 12 mitochondrial protein-coding genes of 76 bivalve species confirms the already known correlation between longevity and generation time and shows, for the first time in an invertebrate class, a significant negative correlation between dS and longevity.
Growth parameters of endangered freshwater pearl mussel (Margaritifera laevis, Unionoida)
Results suggest that margaritiferid mussels in southern regions such as M. laevis in Japan and M. margar itifera in Spain may be particularly vulnerable when conditions are unsuitable for juvenile mussels for prolonged periods.
Cellular stress responses to chronic heat shock and shell damage in temperate Mya truncata
This study demonstrates that discovery-led transcriptomic profiling of animals during stress-response experiments can shed light on the complexity of biological processes and changes within organisms that can be more difficult to detect at higher levels of biological organisation.
Differences in the lifespan of the freshwater pearl mussel Margaritifera margaritifera as evidence for the infeasibility of negligible senescence (Based on data for St. Petersburg and Leningrad oblast)
Examination of individuals that have died in a natural environment suggests that the probability of their death increases with age, i.e., this species is subject to aging, shows that the concept of “negligible senescence” is erroneous.


Variation in the life span and size of the freshwater pearl mussel
Within the distribution area of the freshwater pearl mussel, the maximum observed life span attained in a population varies from 30 to 132 years and the maximum shell length from 80 to 145 mm.

The present symposium in its aims and multi-disciplinary character has much in common with the 1959 CIBA Conference, and the author shall again approach his subject primarily from the demographic standpoint, but this time exploring certain evolutionary implications.
daf-2, an insulin receptor-like gene that regulates longevity and diapause in Caenorhabditis elegans.
Life-span regulation by insulin-like metabolic control is analogous to mammalian longevity enhancement induced by caloric restriction, suggesting a general link between metabolism, diapause, and longevity.
Host Relationships at Reversed Generation Times: Margaritifera (Bivalvia) and Salmonids
The evolution of “covenants” may account for the continued persistence of such host-parasite systems and can be thought as being involved in an arms race where new host defences select for new parasite offences and vice versa.
Extension of life-span by overexpression of superoxide dismutase and catalase in Drosophila melanogaster.
A study of the effects of simultaneous overexpression of copper-zinc superoxide dismutase and catalase provides direct support for the free radical hypothesis of aging.
Amphibian Limb Regeneration: Rebuilding a Complex Structure
The ability to regenerate complex structures is widespread in metazoan phylogeny, but among vertebrates the urodele amphibians are exceptional and the possibility of inducing a blastema on a mammalian limb cannot be discounted.
