The role of ecosystem transpiration in creating alternate moisture regimes by influencing atmospheric moisture convergence por Makarieva, A.M., Nefiodov, A.V., Nobre, A.D., Baudena, M., Bardi, U., Sheil, D., Saleska, S.R., Molina, R.D., Rammig, A.

“…Recently, changes in plant transpiration across the Amazon basin were shown to be associated disproportionately with changes in rainfall, suggesting that even small declines in transpiration (e.g., from deforestation) would lead to much larger declines in rainfall. …”

Bioactive compounds and antioxidant activity in seeds of bred lines of common bean developed from Interspecific crosses por Suárez, Juan Carlos, Polanía-Hincapié, Paola Andrea, Saldarriaga, Sebastian, Ramón-Triana, Vivian Yorlady, Urban, Milan Oldřich, Beebe, Stephen Edgar, Rao, Idupulapati M.

“…The bean genotypes were grown under high temperatures and acid soil conditions in the Amazon region of Colombia. Five typology groups of bean genotypes were identified based on the level of bioactive compounds and their functional capacity: (1) highly bioactive and functional (HBF); (2) moderately bioactive and functional (MBF); (3) moderate antioxidant content with pigment influence (MACP); (4) moderately antinutritional with limited antioxidant potential (MALAP); and (5) antinutritional, low bioactive, and functional (ALBF). …”

Content and distribution of cyanogenic compounds in cassava roots and leaves in association with physiological age por Ospina, María A., Tran, Thierry, Pizarro, Mónica, Luna, Jorge, Salazar, Sandra, Londoño, Luis, Ceballos, Hernan, Becerra Lopez‐Lavalle, Luis A., Dufour, Dominique

“…Genotypes from different regions of Latin America, as identified by seven genetic diversity groups differed significantly in CC levels. The Andean and Amazon groups had, respectively, the lowest (P=0.0008) and highest (P<.0001) CC levels in all three parts of the plants. …”

A spatial perspective to introducing biofortified staple food crops in Colombia por Funes, José, González, Carolina, Perez, S., Birol, Ekin, Moursi, Mourad, Zeller, Manfred

“…Our empirical results show that crops biofortified with zinc, namely white maize and rice, should be introduced in the North Coast of Colombia; crops biofortified with vitamin A, namely yellow maize and cassava, should be introduced primarily in the Atlantic and Amazon regions of the country. Introduction of iron-biofortified beans in the Andean region, especially Tolima and Antioquia, could have the greatest impact. …”

Promoting forest conservation through ecotourism income? por Wunder, Sven

“…This paper sets out a methodological framework for analysis of the alleged participation-income-conservation link, and applies it to the Cuyabeno Wildlife Reserve in the Ecuadorian Amazon region. Three Cuyabeno ethnic groups involved in tourism, the Quichuas, Siona-Secoyas and Cofans, are characterised by different tourism participation models, ranging from autonomous operations to pure salary employment. …”

Landscape rehabilitation of degraded tropical forest ecosystems: case study of the CIFOR/Japan project in Indonesia and Peru por Kobayashi, S.

“…With the Instituto Nacional de Investigacion Agraria (INIA), Peru, the project is trialling revegetation of fallow fields abandoned after agricultural use in the Ucayali region of the Peruvian Amazon. There is specific interest in selecting tree species with high economic value that grow rapidly in abandoned agricultural land and on infertile soils. …”

Biogeography and taxonomy of Mononychellus species associated with Manihot esculenta Crantz in the Americas por Guerrero, J.M., Flechtmann, CHW, Duque E., Myriam Cristina, Gaigl, A, Bellotti, Anthony C., Moraes, G.J. de, Braun, Ann R.

“…We found M. mcgregori Flechtmann and Baker in humid highlands (interandean valleys) of Colombia, Ecuador and Peru, in subtropical southern Brazil, and in the Colombian region of the Amazon Basin (humid lowlands). M. planki (McGregor) was collected from one field in northeast Brazil and from five fields in Colombia. …”

Development of interspecific hybrids between three American yam bean species (Pachyrhizus spp.). por Heider, B., Romero, E., Grüneberg, W.J.

“…In order to increase root dry matter content and promote a wider use of American yam beans for food and starch processing interspecific crosses were made between P. tuberosus (Chuin) germplasm originating from the Peruvian Amazon and two other domesticated yam bean species: P. ahipa native to the Andean highlands and P. erosus originating from Central America. …”

Diversity of fruit fly (Diptera: Tephritidae) Species in French Guiana: their main host plants and associated parasitoids during the period 19942003 and prospects for management por Vayssières, Jean-François, Cayol, J.P., Caplong, P., Seguret, J., Midgarden, D., Sauers-Muller, A., Zucchi, R., Uramoto, K., Malavasi, A.

“…Our data provide baseline information about the tephritid species ofeconomic importance present in French Guiana and assist in developing potential future controlprograms of both the B. carambolae and Anastrepha species in the Amazon Basin. These preliminary results are discussed in the light of their implication for rainforest conservation effortsand also evolutionary relationships between fruit flies and their hosts…”

Does the Establishment of Sustainable Use Reserves Affect Fire Management in the Humid Tropics? por Carmenta, R., Blackburn, G.A., Davies, G., Sassi, Claudio de, Lima, A., Parry, L., Tych, W., Barlow, J.

“…We analyse MODIS derived hot pixels, TRMM rainfall data, Terra-Class land cover data, socio-ecological data from the Brazilian agro-census and the spatial extent of rivers and roads to evaluate whether the designation of SURs reduces fire occurrence in the Brazilian Amazon. Specifically, we ask (1) a. Is SUR location (i.e., de facto) or (1) b. designation (i.e. de jure) the driving factor affecting performance in terms of the spatial density of fires?…”
