Genetic Analysis of Tropical Midaltitude‐Adapted Maize Populations under Stress and Nonstress Conditions

Crop Science, Volume 58, Issue 4, Page 1492-1507, July–August 2018., 2018
Maize (Zea mays L.) yield in sub‐Saharan Africa (SSA) is low because of both abiotic and biotic constraints, and limited availability or use of improved seed in some areas. This study was conducted (i) to estimate combining ability and heterosis among seven stress‐tolerant populations, and (ii) to assess diversity among the populations and the ...

Carbon accumulation in Amazonian floodplain lakes: A significant component of Amazon budgets?

Limnology and Oceanography Letters, Volume 2, Issue 1, Page 29-35, February 2017., 2017
Abstract The Amazon floodplains cover approximately 10% of the Amazon Basin and are composed of predominantly anoxic sediments that may store large amounts of carbon. Our study combines 210Pb derived sedimentation rates from four recently analyzed sediment cores (n = 4) with previously published organic carbon (OC) burial estimates (n = 18) to provide ...

Sistemas cristalinos: nomenclatura e convenções

Terrae Didatica, 2018
Os livros de introdução à cristalografia apresentam os sistemas cristalinos de acordo com o conjunto de elementos de simetria e as orientações axiais dos cristais. Entretanto, o que é fundamental para a definição do sistema cristalino é apenas o conjunto dos elementos de simetria e não as orientações axiais. Alguns dos sistemas cristalinos possuem seus

Environmental and Spatial Processes Drive the Phylogenetic Diversity and Structure of Planktonic Microeukaryotes Revealed by 18S rDNA Metabarcoding in a Tropical Floodplain

Environmental DNA, Volume 8, Issue 3, May–June 2026.
The community structure of photosynthetic planktonic microeukaryotes in the floodplain lakes of the Tocantins‐Araguaia River basin is influenced by a combination of environmental filters and spatial processes. Phylogenetic information from this community highlights the importance of conserving less degraded areas to preserve the evolutionary diversity ...
