Factors influencing organic carbon decomposition of topsoils from the Brazilian Amazon Basin por Koutika, Lydie-Stella, Choné, T., Andreux, F., Burtin, G., Cerri, C.C.

“…The influence of texture and local climate, especially precipitation, on C decomposition was evaluated in topsoils under forest and pastures at different sites located in the western, central, and eastern Brazilian Amazon Basin. Independent of the geographical location and vegetation cover, C decomposition was lower in topsoils of fine texture with a sand/clay ratio of less than 1, compared to topsoils of coarse a texture with a sand/clay ratio ranging from 2 to 8. …”

Uncovering spatial patterns in the natural and human history of Brazil nut (Bertholletia excelsa) across the Amazon Basin por Thomas, E., Alcázar Caicedo, Carolina, McMichael, C.H., Corvera, R., Loo, J.

“…We scrutinized the putative association between Brazil nut and Amazonian Dark Earth soils (ADE) and geometric earthworks called geoglyphs, and examined the existence of continental patterns in human footprints on Brazil nut stands.Amazon Basin.We carried out a spatially explicit meta‐analysis of the variation of Brazil nut stand metrics across the Amazon Basin based on 87,617 density estimates and 488 average stand diameter assessments, and related these to previously published datasets and suitability maps of Brazil nut, ADE and geoglyphs.We found consistently higher Brazil nut suitability scores, stand densities and average stand diameters in the vicinities of ADE than at larger distances, regardless of their position along a gradient from south‐western to north‐eastern Amazonia. …”

Amblyomma parvum Aragão, 1908 (Acari: Ixodidae): Phylogeography and systematic considerations por Lado, Paula, Nava, Santiago, Labruna, Marcelo B., Szabó, Matías P.J., Durden, Lance A., Bermudez, Sergio, Montagna, Matteo, Sánchez Quirós, Ana C., Beati, Lorenza

“…The geographical distribution of Amblyomma parvum Aragão 1908 in the New World is disjunct, with two main clusters separated from each other by the Amazon basin. The main objectives of this study were to further investigate the systematic relationships within A. parvum, to determine whether or not populations from different geographical areas might represent cryptic species, and to reconstruct the phylogeographical evolutionary history of the species. …”
