Neste estudo, fornecemos a descrição da espécie com base nos novos registros, a avaliação preliminar do risco de extinção, pranchas fotográficas, um mapa de distribuição geográfica atualizado, comentários ecológicos, e uma chave de identificação das espécies de Aristolochia subser. Anthocaulicae da Amazônia brasileira.
The lack of synthesized information regarding biodiversity is a major problem among researchers, leading to a pervasive cycle where ecologists make field campaigns to collect information that already exists and yet has not been made available for a broader audience. This problem leads to long-lasting effects in public policies such as spending money multiple times to conduct similar studies in the same area. We aim to identify this knowledge gap by synthesizing information available regarding two Brazilian long-term biodiversity programs and the metadata generated by them.
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.
The aim of the study was to investigate the effects of environmental conditions on the intra- and interspecific variability of WD for tree assemblages in forests of the northern Brazilian Amazon.
Here, we report new records of Scaphyglottis punctulata in two regions of the Brazil portion of the Guiana Shield.
This review of Neotropical Burseraceae emphasizes developments since the last major review of the family in 2011.
The harvesting of açaí berries (palm fruits from the genus Euterpe ) in Amazonia has increased over the last 20 years due to a high local and global market demand and triggered by their widely acclaimed health benefits as a ‘superfood’
The aim of this study was to determine the response of species richness and composition to environmental filters, and analyze the role of P. gracilipes in structuring tree communities in ecotone forest areas of the Northern Brazilian Amazonia.
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.
Protium santamariae is described and illustrated.
Monoterpene ‘fingerprint’ database has important implications for constraining Protium species identification and phylogenetic relationships.
To meet the GSPC goals of Target 1 and facilitate access to plant diversity, Brazil committed to preparing the List of Species of the Brazilian Flora (2008-2015) and the Brazilian Flora 2020 (2016-present).
Macrolobium aracaense (Fabaceae), a new endemic treelet species from Brazil, is here described and illustrated.
This work reports new records of angiosperms to Roraima from two conservation units in the southwest of the state, the Serra da Mocidade National Park and Niquiá Ecological Station.
The aim of this study was to estimate the decomposition rate of coarse woody debris (CWD) in two oligotrophic undisturbed forest formations of the northern Brazilian Amazon: seasonally flooded and unflooded.
The floristic account of the Clethraceae from Bahia State, Brazil, is presented.
An updated inventory of Brazilian seed plants is presented and offers important insights into the country’s biodiversity.
This work presents the taxonomic study of Sapindaceae from three areas of montane forest remnants in southern Bahia, Brazil.
The floristic survey of the Caryocaraceae from Bahia State, Brazil, is presented.
A new species of Paullinia from the Atlantic Forest of southern Bahia, Brazil, is described and illustrated.
These results confirm the high species diversity of angiosperms in southern Bahia and demonstrate for the first time the presence of species characteristic of montane regions of southeastern Brazil in this region.
