Ecotopes are represented by the NTC of interfluvial high plains composed of eluvial-diluvial loams on sod-podzolic loamy soils.
The figure shows ratios of this group of communities in the NTC of interfluvial high plains composed of eluvial-diluvial loams on sod-podzolic loamy soils, which have been attributed to the succession system of lime-oak nemoral forests.
To these must be added the downriver Banaro villages on the Gorogopa River, two villages on the Upper Tamon (Clay River) as well as two other villages situated on the Ramu and a few remaining hamlets in the interfluvial zone in Dugum territory.
For the interfluvial villages, upriver and downriver (top and bottom) correspond respectively to east and west.
Here, Rostain reports unpublished studies of artefacts from museums, offers an authoritative and panoramic overview of some of the most important ceramic traditions of the lowlands, and elaborates the suggestion that the rise of larger and more complex populations in regions adjacent to cultivable floodplains resulted in the displacement of existing small-scale cultivators into the interfluvial
regions that they inhabit today.
The specific location is an interfluvial
(between major river systems) zone along a 126-km petroleum pipeline access road extending in a southeasterly direction from the Rio Napo near Limoncocha [ILLUSTRATION FOR FIGURE 1 & 2 OMITTED].
More than 35 years ago, West (1957) could demystify this evaluation after travelling by canoes and along interfluvial
paths from Panama to Esmeraldas.
