ISDR Working Groups
The The ISDR includes working groups that accomplish goals of our society. Working groups include council members and are open to all society members. What group would you like to join?
DIATOM RESEARCH: Paralia flatoniana sp. nov., a new species from the late Eocene of Texas with discussion on ecology and initial valves
During the Eocene, Gulf of Mexico and volcanism to the west provided a temperate coastal nutrient-rich shelf environment favourable for Paralia.
In memory of René Le Cohu
The International Society for Diatom Research lost one of our esteemed members, René Le Cohu.
DIATOM RESEARCH: Determining geographical range and alien status in diatoms
Three case histories are used to define a series of criteria for establishing geographical range and alien status in diatoms and other microalgae.

The International Society for Diatom Research (ISDR) promotes the study of marine, freshwater, modern and fossil diatoms across the wide range of disciplines of biology, geology, paleoecology, cell metabolism, cell biology, metabolomics, nanotechnology, forensics, systematics, nomenclature, taxonomy, and biogeochemistry. Our society represents investigators from all nations.
