Hi Ross,

I have no personal contacts in this connection, but you might find the home page for Sociedade Brasileira de Malacologia useful (see the links to affiliate societies). In Portuguese but not too hard to follow (and there is always Google Translate). The URL is http://sbmalacologia.com.br/#a.

Cheers Keith

Thanks Keith for your advice, I will try the site. I am seeking to test alternate hypotheses with SA Hyriids of physiological conservatism or zoogeographical vicariance.

cheers, Ross

Ross, See this paper by Argentinian authors in Online Early/Marine and Freshwater Research: Yusseppone et al. 2016. Age- and sex-dependent changes in morphometric and metabolic variables in the long-lived freshwater mussel Diplodon chilensis.

Cheers Keith

Got it!-age distribution would be great enough to adequately allow the bioaccumulation model to be evaluated; will contact the authors, many thanks for your advice, cheers, Ross
