Variable General Info
Vertebrate assemblage (fish & amphibian) metrics ?Comment:This is a file for all the vertebrate taxa collected providing autecological characteristics for each taxon. Normally these variables would be included but given the 600 or so taxa collected, the numbers would overwhelm the VRD and Database if individually entered. |
