Nutrient limitation in three lowland tropical forests in southern China receiving high nitrogen deposition: insights from fine root responses to nutrient additions.

PLoS ONE, 2013
Elevated nitrogen (N) deposition to tropical forests may accelerate ecosystem phosphorus (P) limitation. This study examined responses of fine root biomass, nutrient concentrations, and acid phosphatase activity (APA) of bulk soil to five years of N and ...

Fragmentation Increases Impact of Wind Disturbance on Forest Structure and Carbon Stocks in a Western Amazonian Landscape [PDF]

Tropical second-growth forests could help mitigate climate change, but the degree to which their carbon potential is achieved will depend on exposure to disturbance.

Storm intensity and old-growth forest disturbances in the Amazon region [PDF]

, 2010
We analyzed the pattern of large forest disturbances or blow-downs apparently caused by severe storms in a mostly unmanaged portion of the Brazilian Amazon using 27 Landsat images and daily precipitation estimates from NOAA satellite data.

Kinsenoside Targets IDH1 to Restore Microglial Immune‐Metabolic Homeostasis for Alzheimer's Disease Therapy

Advanced Science, EarlyView.
Dysregulated TCA cycle contributes to Alzheimer's disease (AD) pathogenesis. Here, we show that microglial isocitrate dehydrogenase 1 (IDH1) is a critical driver. Elevated IDH1 disrupts citrate metabolism and mitochondrial function, exacerbating AD pathology.

Land snail diversity can reflect degrees of anthropogenic disturbance [PDF]

, 2013
Faunal indicators of old-growth forests in heavily-disturbed regions are virtually non-existent. However, land snails, in particular micro-snails, could reflect the impact of land-use on ecosystem integrity.

Chitosan‐Carbon Dot Composite Materials Form a Leaf Surface Barrier to Mitigate the Enrichment and Invasion of Nanoplastics: From Leaf Interface to Systemic Response

Advanced Science, EarlyView.
Foliar spraying of CS‐CDs can form a film on the leaves of Brassica rapa, effectively reducing the enrichment and absorption of PS in the leaves, while increasing the biomass and nutrient content of the plants. In addition, CS‐CDs can also enrich the interfoliar microbial community and activate the plant's own defense metabolic pathways.

Old‐Growth Forest Area Projected to Increase on United States Federal Lands Under Alternative Future Scenarios

Earth's Future
Changing climate conditions, wildfires, and tree harvests could affect the area of mature and old‐growth forests in the United States. We used a stochastic modeling system to project future areal extents of mature and old‐growth forests on National ...

West coast, temperate, old-growth forests

The Forestry Chronicle, 2003
Canada's west coast, temperate, old-growth forests include its largest, most commercially valuable, fastest-growing, oldest, and certainly most fought-over forests. They can be divided into three main types: coastal rainforest, coastal subalpine forest, and "rain-shadow" forest.

Effects of management practices on water yield in small headwater catchments at Cordillera de los Andes in southern Chile [PDF]

, 2009
In several parts of the world, drinking water is obtained from springs in natural and managed mountainous forests. Since forests regulate quality as well as quantity of water, the effects of forest-management activities on water yield are an important ...
