Cyrtocarpa is a generic name that has been applied to members of a complex of dry-habitat Neotropical taxa, but recent investigations have revealed that in fact this group represents three distinct genera. Tumultivenia and Uniostium, two new genera of Anacardiaceae-Spondioideae, are described and illustrated, as is one new species, Cyrtocarpa caribaea.
We integrate ecological community metadata of 7,694 sampling sites for multiple organism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change.
Here, we use a machine learning approach to quantify the importance of environmental factors and apply it to generate spatial predictions of the species diversity of all trees (dbh ≥ 10 cm) and for very large trees (dbh ≥ 70 cm) using data from 243 forest plots (108,450 trees and 2832 species) distributed across different forest types and biogeographic regions of the Brazilian Amazon.

Here we tested the accuracy of FT-NIR at discriminating species of the genus Microgramma.
Here, we use a large floristic dataset to show that, while hyperdominance is a universal phenomenon across forest strata, different species dominate the forest understory, midstory and canopy.
Nossa meta é prover uma introdução básica da linguagem de programação R, que é extremamente poderosa para manipulação de dados, análises estatísticas, produção de gráficos e de documentos dinâmicos, e cujo domínio oferece um grande ganho de produtividade a todo cientista e facilita o entendimento de métodos analíticos. Ressaltamos que isto não é um curso de estatística.
