Effects of Small-Scale Gold Mining Tailings on the Underwater Light Field in the Tapajós River Basin, Brazilian Amazon
Artisanal and Small-scale Gold Mining (ASGM) within the Amazon region has created several environmental impacts, such as mercury contamination and changes in water quality due to increased siltation. This paper describes the effects of water siltation on the underwater light environment of rivers under different levels of gold mining activities in the Tapajós River Basin. Furthermore, it invest...
متن کاملBat trypanosomes from Tapajós-Arapiuns Extractive Reserve in Brazilian Amazon.
Trypanosoma comprises flagellates able to infect several mammalian species and is transmitted by several groups of invertebrates. The order Chiroptera can be infected by the subgenera Herpetosoma, Schizotrypanum, Megatrypanum and Trypanozoon. In this study, we described the diversity of bat trypanosomes and inferred phylogenetic relationships among the trypanosomes from bats caught in Tapajós-A...
متن کاملProliferation of Hydroelectric Dams in the Andean Amazon and Implications for Andes-Amazon Connectivity
Due to rising energy demands and abundant untapped potential, hydropower projects are rapidly increasing in the Neotropics. This is especially true in the wet and rugged Andean Amazon, where regional governments are prioritizing new hydroelectric dams as the centerpiece of long-term energy plans. However, the current planning for hydropower lacks adequate regional and basin-scale assessment of ...
متن کاملDistribution of Artisanal and Small-Scale Gold Mining in the Tapajós River Basin (Brazilian Amazon) over the Past 40 Years and Relationship with Water Siltation
An innovative remote sensing approach that combines land-use change and water quality information is proposed in order to investigate if Artisanal and Small-scale Gold Mining (ASGM) area extension is associated with water siltation in the Tapajós River Basin (Brazil), containing the largest small-scale gold mining district in the world. Taking advantage of a 40-year period of the multi-satellit...
متن کاملAnthropophilic black flies (diptera:Simuliidae) in the Amazon national park (Tapajós) and their effects on man.
The family of small biting flies known as the Simuliidae has received increased attention in Brazil since the discovery of onchocerciasis by Berzoti et al. in 1967 (1). In addition, simuliid flies, also known as black flies, piuns, and borruchudos, are responsible for vectoring the more widely distributed Manson& ozzardi, another tilarial parasite of man (2, 3). Besides transmitting pathogens, ...
