Information

Ecological parameter:  temperature according to Tachet

Parameter group: habitat preference parameters

Explanation:
The three trait categories defined for investigating the temperature preferences of taxa, distinguish psychrophilic taxa (i.e. taxa exhibiting distribution limited by water temperature upper than 15°C; 1), from thermophilic taxa (i.e. taxa exhibiting distribution limited by water temperature lower than 15°C; 2) and eurythermic taxa (i.e. taxa able to live in a wide range of temperature; 3).

Additional information:
Note that Several classifications of the Tachet database are on higher taxonomic level than on species level. To display them in the list please enable "include higher taxonomic units" in the "advanced search".
