Pervasive gaps in Amazonian ecological research

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...

Leaf-litter production in human-modified Amazonian forests following the El Niñ...

Made available in DSpace on 2022-04-28T19:41:19Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-09-15; Leaf-litter production is an essential part of the carbon cycle of tropical forests. In the Amazon, it is influenced by climate, presenting high levels during the driest months of the year. However, it is less established how extreme climatic events may impact leaf-litter production in the long term. Ev...

Tracking the impacts of El Niño drought and fire in human-modified Amazonian fo...

Made available in DSpace on 2022-04-28T19:42:03Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-07-27; With humanity facing an unprecedented climate crisis, the conservation of tropical forests has never been so important – their vast terrestrial carbon stocks can be turned into emissions by climatic and human disturbances. However, the duration of these effects is poorly understood, and it is unclear wh...

The contribution of insects to global forest deadwood decomposition

Made available in DSpace on 2022-04-28T19:44:08Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-09-02; The amount of carbon stored in deadwood is equivalent to about 8 per cent of the global forest carbon stocks1. The decomposition of deadwood is largely governed by climate2–5 with decomposer groups—such as microorganisms and insects—contributing to variations in the decomposition rates2,6,7. At the glob...

Comparing contemporary and lifetime rates of carbon accumulation from secondary...

Made available in DSpace on 2022-04-28T19:50:14Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-03-15; Secondary forests (SFs) growing on previously cleared land could be a low-cost climate change mitigation strategy due to their potential to sequester CO2. However, given widespread changes in climate and land-use in the Amazon in the past 20 years, it is not clear whether current rates of carbon uptake ...

Predation on artificial caterpillars following understorey fires in human-modif...

Made available in DSpace on 2022-04-28T19:52:50Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-01-01; Tropical forests are facing several impacts from anthropogenic disturbances, climate change, and extreme climate events, with potentially severe consequences for ecological functions, such as predation on folivorous invertebrates. Folivory has a major influence on tropical forests by affecting plant fit...

Long-term thermal sensitivity of Earth’s tropical forests

The sensitivity of tropical forest carbon to climate is a key uncertainty in predicting global climate change. Although short-term drying and warming are known to affect forests, it is unknown if such effects translate into long-term responses. Here, we analyze 590 permanent plots measured across the tropics to derive the equilibrium climate controls on forest carbon. Maximum temperature is the most important p...
