October 2014 HCMR fieldwork with the Portuguese team
We had a wonderful collaboration with a Portuguese team of specialists working on the biogeography, taxonomy and conservation science of freshwater bivalves, usually called freshwater mussels. These animals are really scarce since they have specialized ecological requirements and are vulnerable to river and lake degradation (habitat disturbance, dessication, pollution). They are really important biogeographical indicators. Scientific work on these bivalves in Greece has really lagged behind and important gaps exist - we don't even know the species' taxonomically valid names. So a phylogeography and systematic distributional survey is imperative. I share some snapshots from our recent fieldwork with Europe's top freshwater mussel specialists and thank them for all they have taught us. Thanks to Manuel Lopez-Lima, Ronaldo Sousa, Amilcar Teixeira, and Simone Varandas. Ioannis Karaouzas from HCMR also shares in this fascinating research project.

|Serious mud work in the canal waters of former Lake Kopais in Beotia Central Greece. Fantastic mussel find here!|

|The inside of a local Anadonta mussel. This specimen is sacrificed in order to collect the shell.|
|Lake Beletsi - last year there were mussels here - this year, only a single living specimen was found!|
|Mussels from Beletsi Lake on Mount Parnitha. Probably introduced with fishes from the Kifissos Basin.|
|The team explores "Secret Lake". Permission was granted to enter the reservoir after a discussion with the local Guards: thanks!|
|Secrete Lake is definitely one of the most beautiful landscapes in Attika. This is only 25 km from Athens!|
|We found no mussels at Secret Lake; so we decided to walk along the shore.|
|These are huge Oriental Planes besides a stream near Secret Lake. Thanks nature.|
|Unusually high autumn water levels at Secret Lake. Yes I forgot my snorkeling gear again!|
|Taking a genetic sample - a small part of the "foot" and gonad.|
|Manuel looks out across Lake Yliki. A unique lake-scape with a tranquility reminiscent of the Aegean islands.|
