Tableau 1

Le pourcentage de recouvrement de l’espèce utilise la médiane des classes d’abondance dominance de Braun-Blanquet. Cette transformation faite, il faut normaliser à 1 la somme des recouvrements d’espèces pour chacune des stations et importer le bloc de données espèces stations, dans la cellule M1 de la feuille de calcul.

The species recovery percentage uses the median of the Braun-Blanquet dominance abundance classes. Once this transformation is done, we must normalize the sum of the cash recoveries for each of the stations to 1 and import the station species data block, into cell M1 of the spreadsheet.

Abondance dominance (Braun-Blanquet, 1964) 5 4 3 2 1 + r
Pourcentage de recouvrement (Dufrêne, 1998) 87,5 62,5 37,5 15 2,5 0,2 0,1
