Surprising chiral composition changes over the Amazon rainforest with height, time and season

Communications Earth & Environment, 2020
The chiral compositions of biogenic volatile organic compounds over the Amazon tropical rainforest vary with height, time of day and season, according to measurements from a 325 m tall tower.

Microbial responses to changes in land use [PDF]

, 2011
Background/Question/Methods Land use change is one of the greatest threats to biodiversity worldwide. This is especially true for land use change that results in the destruction of intact forest, or "deforestation”.

Large seasonal swings in leaf area of Amazon rainforests [PDF]

Proceedings of the National Academy of Sciences, 2007
Despite early speculation to the contrary, all tropical forests studied to date display seasonal variations in the presence of new leaves, flowers, and fruits. Past studies were focused on the timing of phenological events and their cues but not on the accompanying changes in leaf area that regulate vegetation–atmosphere exchanges of energy, momentum ...

The Ethical Dimensions of Climate Change: Rethinking Justice, Responsibility, and Collective Obligation

Sustainable Development, EarlyView.
ABSTRACT Climate change is one of the most profound ethical and existential challenges of the 21st century. Beyond its physical, economic, and environmental consequences, it raises fundamental moral questions about justice, equity, responsibility, and the right to a livable planet.

An investigation into linearity with cumulative emissions of the climate and carbon cycle response in HadCM3LC [PDF]

, 2016
We investigate the extent to which global mean temperature, precipitation, and the carbon cycle are constrained by cumulative carbon emissions throughout four experiments with a fully coupled climate-carbon cycle model.

Rethinking Spatial Prioritisation for Primate Conservation in an Unprotected Intact Forest Landscape in the Gulf of Guinea

Animal Conservation, EarlyView.
This study highlights the importance of the unprotected Yabassi Key Biodiversity Area, Cameroon, for primate conservation in the Gulf of Guinea biodiversity hotspot. We modelled primate distribution patterns and found that historically overlooked parts of the landscape have high species richness and are critical for some threatened species.

Is the social wasp fauna in the tree canopy different from the understory? Study of a particular area in the Brazilian Amazon Rainforest

Sociobiology, 2019
Most studies about the insect community in rainforests only focus on the forest understory, and even though the rainforest canopy is one of the most fascinating and diverse environments, it remains poorly explored.
