PM2.5 Concentration Differences between Various Forest Types and Its Correlation with Forest Structure

open access: yesAtmosphere, 2015
The Plain Forestation Project is an important measure designed to alleviate air pollution in Beijing, the capital of China. Ten commonly cultivated forest types of the Plain Forestation Project were studied at three growth stages of leaves.

Development of forest structure and leaf area in secondary forests regenerating on abandoned pastures in Central Amazonia [PDF]

open access: yes, 2005
The area of secondary forest (SF) regenerating from pastures is increasing in the Amazon basin; however, the return of forest and canopy structure following abandonment is not well understood. This study examined the development of leaf area index (LAI),

Liming enhances soil priming effect in Chinese fir plantation induced by glycine rather than glucose and oxalic acid

open access: yesGeoderma
Liming is a widely adopted strategy to mitigate soil acidification and enhance forest productivity. However, the extent to which liming modulates forest soil priming effects, particularly those induced by distinct root exudate types, remains poorly ...

Forest disturbance and recovery: A general review in the context of spaceborne remote sensing of impacts on aboveground biomass and canopy structure [PDF]

open access: yes, 2009
Abrupt forest disturbances generating gaps \u3e0.001 km2 impact roughly 0.4–0.7 million km2a−1. Fire, windstorms, logging, and shifting cultivation are dominant disturbances; minor contributors are land conversion, flooding, landslides, and avalanches ...

Diazotrophs Show Signs of Restoration in Amazon Rain Forest Soils with Ecosystem Rehabilitation. [PDF]

open access: yes, 2020
Biological nitrogen fixation can be an important source of nitrogen in tropical forests that serve as a major CO2 sink. Extensive deforestation of the Amazon is known to influence microbial communities and the biogeochemical cycles they mediate. However,

Does degradation from selective logging and illegal activities differently impact forest resources? A case study in Ghana [PDF]

open access: yes, 2016
Degradation, a reduction of the ecosystem’s capacity to supply goods and services, is widespread in tropical forests and mainly caused by human disturbance.

Late-successional and old-growth forests in the northeastern United States: Structure, dynamics, and prospects for restoration. [PDF]

open access: yes, 2013
Restoration of old-growth forest structure is an emerging silvicultural goal, especially in those regions where old-growth abundance falls below the historic range of variability.

Ancient Amazonian populations left lasting impacts on forest structure [PDF]

open access: yes, 2017
Amazonia contains a vast expanse of contiguous tropical forest and is influential in global carbon and hydrological cycles. Whether ancient Amazonia was highly disturbed or modestly impacted, and how ancient disturbances have shaped current forest ...

Spaceborne LiDAR for characterizing forest structure across scales in the European Alps

open access: yesRemote Sensing in Ecology and Conservation, 2023
The launch of NASA's Global Ecosystem Dynamics Investigation (GEDI) mission in 2018 opens new opportunities to quantitatively describe forest ecosystems across large scales. While GEDI's height‐related metrics have already been extensively evaluated, the

Assessment of ecosystem integrity of lowland dipterocarp forest ecosystem using remote sensing [PDF]

open access: yes, 2021
Ecosystem Integrity Index (EII) is a concept to determine the quality or the health of an ecosystem. The EII development can assist forest managers and decision makers in the conservation effort and forest management in Malaysia through the development ...
