Screening of plants found in Amazonas State for lethality towards brine shrimp [PDF]

open access: yesActa Amazonica, 2003
226 methanol and water extracts representing 74 mainly native plant species found in Amazonas State, Brazil, were tested at a standard concentration of 500 μg/mL for lethality towards larvae of the brine shrimp species Artemia franciscana.

Extinction risks of Amazonian plant species [PDF]

open access: yesProceedings of the National Academy of Sciences, 2009
Estimates of the number, and preferably the identity, of species that will be threatened by land-use change and habitat loss are an invaluable tool for setting conservation priorities. Here, we use collections data and ecoregion maps to generate spatially explicit distributions for more than 40,000 vascular plant species from the Amazon basin ...

Eighty-four per cent of all Amazonian arboreal plant individuals are useful to humans.

open access: yesPLoS ONE, 2021
Plants have been used in Amazonian forests for millennia and some of these plants are disproportionally abundant (hyperdominant). At local scales, people generally use the most abundant plants, which may be abundant as the result of management of ...

open access: yesDas Amazônias, 2023
The Amazon region is widely known for its rich biodiversity (SCHUBART, 1990) and the ancestral knowledge of the populations that have inhabited it since ancient times are fundamental in dealing with this issue.

Increasing dominance of large lianas in Amazonian forests [PDF]

open access: yes, 2002
Ecological orthodoxy suggests that old-growth forests should be close to dynamic equilibrium, but this view has been challenged by recent findings that neotropical forests are accumulating carbon and biomass, possibly in response to the increasing ...

Effects of forest fragmentation on the vertical stratification of neotropical bats [PDF]

open access: yes, 2020
Vertical stratification is a key component of the biological complexity of rainforests. Understanding community- and species-level responses to disturbance across forest strata is paramount for evidence-based conservation and management.
