Résumé :
|
Benthic diatoms are useful for monitoring the ecological status of freshwater as required by legislation such as the water framework directive. This key includes the information you need to identify all British and Irish freshwater diatom genera. It also contains data for identifying the species that feature in common indices for assessing trophic state. This key is based on Lucid software, which enables you to choose the characteristics you want for identification.
