Multifaceted Assessment of Amazonian Tree Diversity Reveals Pervasive Impacts of Human Modification. [PDF]

Glob Chang Biol
Amazonian forests impacted by humans have a reduced and different group of tree species than those forests that have never been impacted. The trees present in forests impacted by humans also have different evolutionary histories and functional characteristics.

Potências em Queimada! (1969)

História Revista, 2023
Aliando um contexto histórico de inquietação, o didatismo e a força das imagens, o filme Queimada! (1696), do diretor italiano Gillo Pontecorvo, consegue construir uma via de comunicação eloquente com o espectador e, dessa forma, transmitir de forma manifesta como funcionam as engrenagens exploratórias do colonialismo.

Past human‐induced ecological legacies as a driver of modern Amazonian resilience

People and Nature, Volume 5, Issue 5, Page 1415-1429, October 2023., 2023
Abstract People have modified landscapes throughout the Holocene (the last c. 11,700 years) by modifying soils, burning forests, cultivating and domesticating plants, and directly and indirectly enriched and depleted plant abundances. These activities also took place in Amazonia, which is the largest contiguous piece of rainforest in the world, and for

Procedimentos no uso de drones para validar a detecção de queimadas por satélites

Biodiversidade Brasileira, 2019
Os incêndios florestais destroem anualmente extensas áreas de vegetação, causando grandes prejuízos ambientais e econômicos. Muitos produtos derivados das observações de satélites têm sido utilizados para monitorar eventos de fogo. No Brasil, o Programa

Fish on Fire: Shifts in Amazonian fish communities after floodplain forest fires

Journal of Applied Ecology, Volume 60, Issue 8, Page 1637-1646, August 2023., 2023
Amazonian fish communities change after floodplain forest fires. Unburnt forests have diverse fish communities, with a large proportion of unique and small omnivorous species. In contrast, carnivores and detritivores become more common in fire scars and white‐sand savannas formed after forest fires. Less omnivore fish after forest fires can reduce tree

Incêndios, queimadas e arboviroses

Revista Científica ANAP Brasil, 2021
A pesquisa buscou identificar e caracterizar as relações entre saúde e ambiente no domínio das notificações confirmadas das arboviroses. Buscou-se elucidar como a perda de vegetação nativa local pela ocorrência de incêndios e queimadas pode afetar a saúde humana e potencializar a incidência de arboviroses (Dengue, Zika vírus, Chikungunya e Febre ...

Towards a whole‐system framework for wildfire monitoring using Earth observations

Global Change Biology, Volume 29, Issue 6, Page 1423-1436, March 2023., 2023
Earth observation data are critical for monitoring fires and their impacts as fire seasons become less predictable. In this manuscript, we draw upon multiple disciplines to present a whole‐system framework for identifying and synthesizing fire monitoring objectives and data needs throughout the life cycle of a fire event.

A comparison of land cover maps to define vegetation classes of fire risk in Brazil

Biodiversidade Brasileira, 2019
Natural fires are essential in the structure and functioning of many ecosystems in the world. Some vegetation types are more vulnerable to fire, e.g.tropical forests, whereas others are fire dependent, like savannas.

Activating dark earths: somatosoils and the carbonic loops of Amazonian ecologies

Journal of the Royal Anthropological Institute, Volume 28, Issue 3, Page 854-874, September 2022., 2022
Abstract Inspired by the fertility and climate change‐mitigation properties of the so‐called Amazonian Dark Earths (ADEs), soil science has devised a technoscientific replica, a soil amendment known as biochar, intended to improve agricultural sustainability and carbon storage in the biosphere. Drawing on fieldwork with Afroindigenous horticulturalists,
