Abstract:
In northern South America, an extensive tropical lowland runs 5,000 km from the Atlantic coast to the foot of the Andes. The slope is gentle until about 500 m where the eastern Andes rise abruptly. The lowland supports Amazonia, which is the most extensive tract of tropical rainforest on the planet. Most of its boundaries are well defined, but the boundary between Amazonia and the forest of the eastern slopes of the Andes has not been clearly defined. To determine for avifauna whether Amazonia is restricted to the lowland of northern South America or whether it also extends up into the eastern

Abstract:
Four new species of Lispinus from the premontane forest of the eastern slope of the Peruvian Andes are described and records of all other Lispinus species from Peru are given. The new species are: L. blandus, L. minimus, L. speciosus, and L. peruanus. A key to the known 21 Peruvian species is provided, habitat information is summarized and geographical distribution of species is discussed. The following six types of zoogeographic distribution can be differentiated for the Peruvian Lispinus species: endemic, eastern Andean, lowland Amazonian, Circum-Amazonian, northern Southand Central-American

AbstractWe report the first record of the rare Koepcke’s spear-nosed bat Gardnerycteris koepckeae collected outside of Peru, based on morphological and cytochrome b data. The species was found at the National Natural Park Alto Fragua Indi-Wasi, Department of Caquetá, Colombia. This record extended the species distribution 1400 km north from the northernmost known locality in Huanhuachayo, Ayacucho, Peru. This finding suggests that G. koepckeae is distributed over middle elevations along the eastern slope of the Andean-Amazonia foothills in Peru and Colombia, similar to other Phyllostomid bats,

Abstract. Podzol-ferralsol soil systems cover great areas in Amazonia and in other equatorial regions, they are an end-member of old equatorial landscape evolution, are frequently associated with kaolin deposits and store and export large amounts of carbon. Their biogeochemistry was usually inferred from soil mineralogy and from spring or river water properties. This paper presents a database for groundwaters sampled in situ in a typical podzol-ferralsol soil catena from the Alto Rio Negro region, Brazil; the sampling periods allowed to sample under high- and low-level water-table conditions.

La dissipation de l'énergie associée à la marée interne engendre un intense mélange vertical qui influence la température de l'océan sur toute la colonne d'eau jusqu'en surface, ce qui a un impact significatif pour circulation thermohaline, pour le mélange profond, et pour la convection nuageuse, concernant le mélange plus en surface.

This volume brings together archaeologists working in Ecuador, Peru, and Bolivia to construct a new prehistory of the Upper Amazon, outlining cultural developments from the late third millennium B.C. to the Inca Empire of the sixteenth century A.D. Encompassing the forested tropical slopes of the eastern Andes as well as Andean drainage systems that connect to the Amazon River basin, this vast region has been unevenly studied due to the restrictions of national borders, remote site locations, and limited interpretive models. The Archaeology of the Upper Amazon unites and builds on recent field

Abstract:
Abstract Most raised fields provide for drainage by means of elevated surfaces in association with surrounding ditches which catch water, drain subsoils, and in some instances remove water from the field vicinity, both on flats and on slopes. In addition, there are examples of drainage by ditching alone without raised planting surfaces or with only minimal raising from earth removed from narrow, shallow ditches. Some of the prehistoric Mayan drained fields in Belize are believed to be primarily ditched or channelized fields (Turner 1983; Pohl and Bloom 1996).

Abstract Agricultural technology and the human management of the natural environment for the cultivation of domesticated plants, involves crops, tools, and the processes and forms of environmental modification. Agricultural fields can be divided into those that are artificial in terms of significant degree of surface modification and those that are not. The latter are usually rainfed or located where water is concentrated; they often have good soils; and they are mostly on gentle slopes. However, for past times our best evidence is the forms of manmade agricultural features (agricultural landf

Terra firme forests are those that by definition are not permanently or seasonally flooded (terra firme meaning “firm terrain”). This type of forest encompasses the Amazon and Orinoco basins, stretching from the lower slopes of the Andes, east to the Guianas, and south to about 15°S in western Brazil and northern Bolivia (Richards 1996). Structural and compositional variability in these forests in the Amazon basin is very wide as a result of climate differences and geomorphological position. The region is not climatically uniform; the central and much of the southern parts have less and more s
