Floristic Composition and Structure of a Montane Evergreen Forest at 600- 700 m AMSL in the Piatúa River Basin, Napo, Ecuador
An ecological structural floristic study was carried out in five permanent transects in montane in the Piatúa River basin between 600 and 700 m.a.s.l. There were identified 32 families and 68 species in 288 tree subjects with a recorded DAP ≥ 10 cm. The most diverse families were: Arecaceae, Fabacea...

| Sumario: | An ecological structural floristic study was carried out in five permanent transects in montane in the Piatúa River basin between 600 and 700 m.a.s.l. There were identified 32 families and 68 species in 288 tree subjects with a recorded DAP ≥ 10 cm. The most diverse families were: Arecaceae, Fabaceae and Moraceae with 5 species (7.14 %); followed by Lauraceae and Urticaceae with 4 species (5.71 %); Euphorbiaceae, Myristicaceae, and Vochysiaceae with 3 species (4.29 %). Results show similarities in families from the measured transects where predominate the Arecaceae 17.64%; followed by the Lauraceae, 14.62%; Vochysiaceae 9.80%; Myristicaceae 8.75%, Sterculiaceae 8.21%, and lastly families Hypericaceae 0.10%, Rutaceae 0.10%, and Nyctaginaceae con 0.09%. The most diverse families were, according to Sorensen’s index, transects 2 – 3 and 3 – 5, which are in Rank III with more than 50% similarity. Shannon’s index (3.52) and Simpson’s (0.94) show the presence of a medium-high floristic composition characteristic of foothills ecosystems. |
