Abstract:

The taxonomic histort of the genus Capirona is presented. Complete synonymies, descriptions, common names, distributions and discussions are given for Capirona and its two species C. descorticans and C. leiophloea. The generic distribution is the Amazon valley and eastern Guianas and coincides with that of the genus Hevea. C. descorticans is know from the western and southeastern Amazon valley; C. leiophloea is reported from the eastern Guianas and the northeastern Amazon valley. The zone of contact between the two species is along the southern edge oh the Amazon River and the lower drainage o

Abstract:

The content of sediment forming minerals in two cores from the eastern (ANS45-37) and western (ANS45-48) parts of the Vema transform fault valley is studied using the semi-quantitative XRD analysis of bulk powder sediment samples. The mineral composition of deep-sea sediments from the Amazone cone is also analyzed for comparison. It appeared that the average composition of the terrigenous component of both cores (according to prevailing quartz, secondary mica, plagioclase and potassium feldspar, as well as smectite, chlorite, kaolinite, illite) is quite similar and approximately corresponds to

Abstract:

In the Central Andes of Peru, convective and stratiform rainfall occurs, frequently associated with convective storms. The raindrop size distributions (RSD), measured by a Parsivel-2 optical disdrometer, were characterized by the variation of their normalized parameters. The RSD dataset includes measurements corresponding to 18 months between 2017 and 2019. As a result, it was found that the mass-weighted mean diameter Dm and the Nw parameter present respectively high and low values, in the interval of 15–20 LST (local standard time), wherein deeper and more active clouds appear.

It is a member of the Panoan family and thus is related to such languages as Capanahua, Amahuaca and Chacobo.

The valleys with sandy podzols are occupied by the ‘Amazon caatinga’ complex with three distinct zones: the bottom valley and the gentle slopes, both of which have closed forests, and the sandy domes with open forests (‘bana’ or sclerophyllous forest; Breimer 1985).

Abstract:

The forests of the Amazon basin are threatened by climate and land use changes. Due to the transition towards a drier climate, moisture-dependent organisms such as canopy epiphytes are particularly affected. Even if the topography in the Amazon lowland is moderate, mesoscale nocturnal katabatic flows result from cold air production related to radiative cooling. From a certain level of mass the cold air starts to flow downslope towards the valley centers leading to temperature inversions. The resulting cooling in the valleys drives localized fog formation in the valleys at night. This correlate

Abstract:

The acai palm tree is a species of multiple use and of great importance for the Amazonian economy and riverside families. The high appreciation of the acai berry in the national and international markets contributes to the search for new producing areas and the reduction of repressed demand. This research aimed to identify the knowledge of the riverside families about the acai berry extraction activity in the Araguari river valley. The study was between the municipalities of Ferreira Gomes and Cutias, in an extension of 80 kilometers. The properties were sampled according to the following crit

Objective: The purpose of this study was to evaluate selected Brazilian plants from Juruena valley region of Mato Grosso, for their in vitro antimicrobial and antioxidant activities.Methods: The powder obtained from different parts of the twenty-six (26) plants were macerated in hydroethanolic solution to obtain the extracts. The hydroethanolic extracts were tested for their in vitro antimicrobial activity by determining the MIC using broth microdilution. The 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical, ferric reducing antioxidant power (FRAP) and nitric oxide (NO) methods were used for the

Abstract:

1. Zinc metabolism has been studied in a group of undernourished, slum-dwelling, lactating women in Manaus, Brazil, by means of modified metabolic balance techniques and the stable isotope 67Zn.2. The subjects were found to be consuming a diet which provided an average of 34% of the recommended dietary allowance for lactating women, but six of the seven appeared to achieve Zn balance. In five of the subjects use of 67Zn in a stable isotope dilution manner demonstrated that they were absorbing a high proportion of the dietary Zn (proportional absorption ranged from 0·59 to 0·84), suggesting an

Abstract:

Two new species of Leurotrigona are described: L. crispula sp. nov., from the Magdalena River valley, Antioquia, Colombia, and L. gracilis sp. nov., from western Amazon. Additional geographic records and illustrations are provided for L. muelleri (Friese) and L. pusilla Camargo & Moure, as well as an identification key to the species of the genus. Species can be recognized mainly by pilosity on the face. Morphological characters, including shape of the head and tibia III of the workers, and genitalia and pre-genital sterna of the male are indicative of two distinct groups, one composed of

Abstract:

Henry Walter Bates was born in Leicester, England, on 8 February 1825. Early in life he developed a keen interest in natural history in general, and in insects in particular. He met and befriended Alfred Russel Wallace, and in 1848 the two embarked on a collecting expedition to the Amazon Valley. They soon parted company and thereafter collected separately in different areas of Amazonia. Bates returned to England 11 years later, in 1859. He was quick to embrace Darwin's and Wallace's theory of evolution by natural selection, and was one of the first to back the theory with evidence from the na
