Carbon recovery dynamics following disturbance by selective logging in Amazonian forests

open access: yeseLife, 2016
When 2 Mha of Amazonian forests are disturbed by selective logging each year, more than 90 Tg of carbon (C) is emitted to the atmosphere. Emissions are then counterbalanced by forest regrowth.

Transport of North African dust from the Bodélé depression to the Amazon Basin: a case study [PDF]

open access: yesAtmospheric Chemistry and Physics, 2010
Through long-range transport of dust, the North-African desert supplies essential minerals to the Amazon rain forest. Since North African dust reaches South America mostly during the Northern Hemisphere winter, the dust sources active during winter are ...

Changing patterns of fire occurrence in proximity to forest edges, roads and rivers between NW Amazonian countries [PDF]

open access: yesBiogeosciences, 2017
Tropical forests in NW Amazonia are highly threatened by the expansion of the agricultural frontier and subsequent deforestation. Fire is used, both directly and indirectly, in Brazilian Amazonia to propagate deforestation and increase forest ...

Prospecting of Architectural Features Using LiDAR‐UAV Technology, Deep Neural Networks and Visualization Techniques: A Case Study in Kuélap and Cambolín (NW Peru)

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT High‐resolution and accurate synoptic images of terrestrial topography, even in densely forested areas, have proven valuable for archaeology by enabling the identification and characterization of relief patterns associated with ancient human activities. This study presents a novel approach that integrates digital terrain models (DTMs) obtained

Avifaunal inventory of a Southern Amazonian transitional forest site: the São Luiz farm, Mato Grosso, Brazil [PDF]

open access: yesBoletim do Museu Paraense Emílio Goeldi. Ciências Naturais, 2011
This paper describes the avifauna sampled at the São Luiz farm, in Northern Mato Grosso State, a SouthernBrazilian Amazonian forest site. The avifauna was sampled at forested and open sites, between 29 June and 27July 2008, using point counts, mist-nets ...

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

open access: yesBiological Reviews, EarlyView.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Species distribution modeling reveals strongholds and potential reintroduction areas for the world's largest eagle.

open access: yesPLoS ONE, 2019
The highly interactive nature of predator-prey relationship is essential for ecosystem conservation; predators have been extirpated, however, from entire ecosystems all over the Earth. Reintroductions comprise a management technique to reverse this trend.

Cytogenetic data for sixteen ant species from North-eastern Amazonia with phylogenetic insights into three subfamilies [PDF]

open access: yesComparative Cytogenetics, 2020
Ants play essential roles in most terrestrial ecosystems and may be considered pests for agriculture and agroforestry. Recent morphological and molecular data have challenged conventional ant phylogeny and the interpretation of karyotypic variations ...

Rarity of monodominance in hyperdiverse Amazonian forests. [PDF]

open access: yes, 2019
Tropical forests are known for their high diversity. Yet, forest patches do occur in the tropics where a single tree species is dominant. Such "monodominant" forests are known from all of the main tropical regions. For Amazonia, we sampled the occurrence

The impacts of biological invasions

open access: yesBiological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological
