The Tropical managed Forests Observatory: a research network addressing the future of tropical logged forests [PDF]

open access: yes, 2019
While attention to logging in the tropics has been increasing, studies on the long-term effects of silviculture on forest dynamics and ecology remain scare and spatially limited.

Increasing turnover through time in tropical forests [PDF]

open access: yes, 1994
Tree turnover rates were assessed at 40 tropical forest sites. Averaged across inventoried forests, turnover, as measured by tree mortality and recruitment, has increased since the 1950's, with an apparent pantropical acceleration since 1980.

Coupled Above‐ and Belowground Ecosystem Stability Worldwide

open access: yesAdvanced Science, EarlyView.
Are the worlds above and below our feet in sync? This global exploration reveals an entangled fate between above‐ and belowground ecosystem stability. It identifies arid regions as hotspots for this coupling and highlights temperature stability as a vital safeguard for maintaining ecosystem balance across our warming planet.

The main challenges of sustainable forest management in the Amazon: why sustainable forest management in the Amazon should be reinforced? [PDF]

open access: yes, 2019
Since the last 50 years, tropical natural forests have been intensively logged in the tropics to supply the increasing demand of tropical timber. Unplanned logging operations caused forest degradation leading to their conversion due to the loss of their ...

eQTL Meta‐Analysis Reveals Conserved and Population‐Specific Regulatory Variation Underlying Nutritional Trait Evolution and Domestication in Tomato

open access: yesAdvanced Science, EarlyView.
A comprehensive meta‐analysis of expression quantitative trait loci (eQTLs) across five diverse tomato populations reveals a high‐resolution atlas of transcriptional regulation and uncovers conserved and population‐specific regulatory architectures underlying fruit nutritional quality traits, including flavonoids, sugars, organic acids, carotenoids ...

Global Nitrogen Deposition Promotes Carbon Sink Formation in Terrestrial Ecosystems

open access: yesAdvanced Science, EarlyView.
Nitrogen deposition alleviates ecosystem N limitation and enhances carbon sinks. Using 829 observations, we show 36% of deposited N is retained globally (39.15 Tg N yr−1), with distinct NHx and NOy contributions. This retention drives a terrestrial C sink of 0.88 Pg C yr−1 (25.48%), highlighting the importance of pool‐specific C:N stoichiometry ...

Microplastic characteristics in several land covers in Banda Aceh and Aceh Besar [PDF]

open access: yesBIO Web of Conferences
Plastic is one of the materials that is often used by people who are difficult to decompose. The decomposed plastic will become several parts which are termed macro plastic and micro plastic.

Plant Diversity Patterns and Their Determinants Across a North-Edge Tropical Area in Southwest China

open access: yesDiversity
Understanding the diversity patterns within a region is helpful for the implementation of conservation management. Xishuangbanna, located in southwestern China, is notable for its diverse plant species and belongs to a tropical–subtropical transition ...

Bidirectional drought‐related canopy dynamics across pantropical forests: a satellite‐based statistical analysis

open access: yesRemote Sensing in Ecology and Conservation, 2022
Droughts cause extreme anomalies in tropical forest growth, but the direction and magnitude of tropical forests in response to droughts are still widely debated. Here, we used four satellite‐based canopy growth proxies (CGPs), including three optical and
