Pervasive gaps in Amazonian ecological research

Carvalho, Raquel L.; Resende, Angelica F.; Barlow, Jos; França, Filipe M.; Moura, Mario R.; Maciel, Rafaella; Alves-Martins, Fernanda; Shutt, Jack

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain underst...

Made available in DSpace on 2022-04-28T19:26:16Z (GMT). No. of bitstreams: 0 Previous issue date: 2015-01-01; The Amazon basin comprises the largest continuous expanse of tropical forests in the world, covering about 78% of the basin’s 7 million km2 (Goulding et al. 2003). Despite the predominance of upland (“terra firme”) forests, the Amazon is recognized by its large network of large rivers, fueled by precipi...

Dissemination of COVID-19 in cities and riverine communities in Central Amazonia

Ramalho, Emiliano Esterci; Junqueira, Ivan; Baccaro, Fabrício; Hill, Alison L.; Martins, Maria Isabel F. P. O.; Barcelos, Daniele Cristina

The population of small towns and riverine communities in Amazonia are extremely vulnerable to COVID-19 due to the absence of basic health care infrastructure in the region. The objective of this study was to (1) evaluate the effect of social distancing measures in the dissemination of COVID-19 in small towns, and (2) to estimate the impact of reducing contact between rural and urban populations on the contamin...

Spatial patterns of medium and large size mammal assemblages in várzea and terr...

Alvarenga, Guilherme Costa; Ramalho, Emiliano Esterci; Baccaro, Fabricio Beggiato; Rocha, Daniel Gomes da; Ferreira-Ferreira, Jefferson

Várzea forests account for 17% of the Amazon basin and endure an annual inundation that can reach 14 m deep during 6–8 months. This flood pulse in combination with topography directly influences the várzea vegetation cover. Assemblages of several taxa differ significantly between unflooded terra firme and flooded várzea forests, but little is known about the distribution of medium and large sized terrestrial ma...
