Abstract:

We present the first record for Loxosceles gaucho Gertsch, 1967 in the Amazonian region of Brazil. Four males, fifteen females and forty-nine immatures were collected in different places in Manaus, Amazonas, Brazil. This is the third species of Loxosceles reported in the Amazon region along with L. amazonica Gertsch, 1967, and L. similis Moenkhaus, 1898. This is the first record of an invasive species of a venomous animal in the state of Amazonas, Brazil, which is noteworthy due to its synanthropic habit, which increases the risk to the local population.

(Uploaded by Plazi for the Bat Literature Project) Brazil holds nearly 15% of world's bat species richness, and most of it is present in the Amazonian biome. Here we present an updated compilation of bat species for the Brazilian Amazonia, with records of 146 species, belonging to nine families and 64 genera. At least 46 of those species are currently restricted to the Amazonian biome. Pará State is the species richest (120 spp.) and the Amazonian portion of Maranhão the least (21 spp.). Nine species were recorded in all the Amazonian States, and 28 are restricted to a single state. The specie

Abstract:

This investigation offers an analysis of the variation in the expression of purpose relations in a sample of 49 Amazonian languages. The most common strategies are conjunctions and converbs. Interestingly, in a number of Amazonian languages, positive purpose meanings are expressed with a conjunction or a converb in combination with other morphosyntactic properties. We briefly examine the areality of positive purpose clause-linkage patterns in four contact zones in the Amazonia: the Vaupés region, the Caquetá-Putumayo region, the Southern Guiana region, and the Marañon-Huallaga region.

During the twentieth century, Amazonia was widely regarded as relatively pristine nature, little impacted by human history. This view remains popular despite mounting evidence of substantial human influence over millennial scales across the region. Here, we review the evidence of an anthropogenic Amazonia in response to claims of sparse populations across broad portions of the region. Amazonia was a major centre of crop domestication, with at least 83 native species containing populations domesticated to some degree.

At the Amazonian scale, we expected Anisoptera metacommunities to be randomly distributed due to their higher dispersal ability and large environmental tolerance.

Abstract:

This paper reviews reports of nitrous oxide (N2O) and nitric oxide (NO) emissions from soils of the Amazon and Cerrado regions of Brazil. N2O is a stable greenhouse gas in the troposphere and participates in ozone-destroying reactions in the stratosphere, whereas NO participates in tropospheric photochemical reactions that produce ozone. Tropical forests and savannas are important sources of atmospheric N2O and NO, but rapid land use change could be affecting these soil emissions of N oxide gases. The five published estimates for annual emissions of N2O from soils of mature Amazonian forests a

Abstract:

AbstractA product native to the Amazon forest, cacao became the most important staple of the Portuguese Amazonian colonial economy from the late seventeenth until the mid-nineteenth century. Based on extensive research in Brazilian and European archives, this article analyses cacao exploitation in Portuguese Amazonia, examining its dual spatial dimension: the expansion of an agricultural frontier, and the expansion of an extractive frontier in the deep hinterland, with a particular focus on the role that Indian labour played in this development.

So far, limited work that represents Amazonian urban regions has been carried out. (2) methods: Our study area is the Ecuadorian Amazon. We performed a K-means algorithm using six urban indicators: Urban fractal dimension, number of paved streets, urban radiant intensity (luminosity), and distances to the closest new deforested areas, to oil pollution sources, and to mining pollution sources.

Abstract Phyllomedusa bicolor is a large-sized nocturnal tree frog found in tropical rainforests throughout much of the Amazonian region of Brazil, Colombia, Bolivia, Peru, Venezuela, and the Guianas. Very little is known about P. bicolor genetic diversity and genealogical history of its natural populations. Here, using a sampling design that included populations covering most of its distributional range, we investigated the spatial distribution of genetic variability of this species, and we tested the hypothesis that P. bicolor is composed of deeply structured genetic groups, constituting mor

Concern over the fate of the rain forest and peoples of Amazonia has inspired a renewed interest in the extraction of natural products from the region. Accounts of the Amazon Rubber Boom (1860–1910) are of particular interest in view of the dominance of the rubber industry during one of the most influential periods in the region's history as well as the continuing economic importance of wild rubber extraction to thousands of Amazonian households today. For many observers, the organisation and performance of the wild rubber industry – then and now – provides a good illustration of extractive in

A new genus and species of short-tailed whipscorpion (Schizomida: Hubbardiidae Cook, 1899) is described based on specimens collected in the Venezuelan state of Amazonas. The new genus differs from other Neotropical genera in the presence of six setae on opisthosomal tergite II, the absence of seta Dm4 on the flagellum in both sexes, the female flagellum comprising four segments, and the median lobes of the spermatheca being four times longer than the lateral lobes. Jipai longevus gen. et sp. nov. increases the count of South American schizomid genera to fourteen and the count of species to 57.

Peru is one of the world’s main coffee exporters, whose production is driven mainly by five regions and, among these, the Amazonas region. However, a combined negative factor, including, among others, climate crisis, the incidence of diseases and pests, and poor land-use planning, have led to a decline in coffee yields, impacting on the family economy. Therefore, this research assesses land suitability for coffee production (Coffea arabica) in Amazonas region, in order to support the development of sustainable agriculture.

Abstract:

In Amazonia, monumentality has traditionally been considered characteristic of the late pre-colonial densely populated complex societies. Recent archaeological fieldwork concerning the geometric earthworks in the Brazilian state of Acre has shown that the southwestern Amazonian interfluvial zone was a significant setting for long-term large landscape modifications. We describe the geometric ditched enclosure sites of Acre as early monumental public spaces reserved for ceremonial purposes, analogous to the central Andean ceremonial-civic centers of the Formative period.
