<I>Thozetella coronata</I> and <I>T.ypsiloidea</I> spp. nov. from the Brazilian Amazon forest

Screening of antibacterial extracts from plants native to the Brazilian Amazon Rain Forest and Atlantic Forest.

More than 20% of the world's biodiversity is located in Brazilian forests and only a few plant extracts have been evaluated for potential antibacterial activity. In the present study, 705 organic and aqueous extracts of plants obtained from different Amazon Rain Forest and Atlantic Forest plants were screened for antibacterial activity at 100 microg/ml, using a microdilution broth assay against...

Remote Monitoring for Forest Management in the Brazilian Amazon

Ocimum gratissimum, from Brazilian Amazon

Alfavaca, Ocimum gratissimum (Labiatae), ap­ pears to have been introduced by slaves from Afri­ ca by the Portuguese in the 16th or 17th century or it may be a geographical variety native to Brazil, its origin is still doubt. The shrub-like plant is cul­ tivated in the country-sides of the State of Para and sold in the “Ver-o-peso” market in Belem. It is utilized as a condiment in regional dish...

The changing Amazon forest

Long-term monitoring of distributed, multiple plots is the key to quantify macroecological patterns and changes. Here we examine the evidence for concerted changes in the structure, dynamics and composition of old-growth Amazonian forests in the late twentieth century. In the 1980s and 1990s, mature forests gained biomass and underwent accelerated growth and dynamics, all consistent with a wide...

Two new species of Phalangopsis Serville, 1831 (Orthoptera: Grylloidea: Phalangopsidae) from Brazilian Amazon Forest.

We describe here two new species of the genus Phalangopsis Serville, 1831 from the Brazilian Amazon Forest. The male genitalia and the female copulatory papilla were described, and a combination of diagnostic characteristics was given to separate both new species from the other described species. The principal morphological characteristics of this genus were discussed.
