Coupling Photosynthetic Measurements with Biometric Data to Estimate Gross Primary Productivity (GPP) in Mediterranean Pine Forests of Different Post-Fire Age
Pinus brutia carbon fluxes leaf area index light response curve conifer forests
2023/12/15
Quantification of forest Gross Primary Productivity (GPP) is important for understanding ecosystem function and designing appropriate carbon mitigation strategies. Coupling forest biometric data with ...
Intraday Variation Mapping of Population Age Structure via Urban-Functional-Region-Based Scaling
age structure urban functional regions temporal scaling factor dasymetric model RF-RFE algorithm intraday variation map
2023/12/6
The spatial distribution of the population is uneven?for various reasons, such as urban-rural differences and geographical conditions differences. As the basic element of the natural structure of the ...
Species- and Age-Specific Growth Reactions to Extreme Droughts of the Keystone Tree Species across Forest-Steppe and Sub-Taiga Habitats of South Siberia
tree rings drought sensitivity resistance resilience age habitat differences
2023/12/1
Over the coming decades, climate change can decrease forest productivity and stability in many semiarid regions. Tree-ring width (TRW) analysis allows estimation of tree sensitivity to droughts, inclu...
Duration of Climate Change Mitigation Benefits from Increasing Boreal Forest Harvest Age by 10 Years
composite yield curves carbon curves mitigation benefit stand scale
2023/12/1
We presented a case study and associated method for stand scale assessment of the duration of the climate change mitigation benefit provided by increasing forest harvest age (i.e., the age a stand is ...
Age-independent diameter increment models for mixed mountain forests
Age-independent growth equations Algebraic difference approach Mixed effects models Uneven-aged forest Mixed species forests Growth index
2023/11/20
Mixed mountain forests with an uneven-aged structure are characterized by a high tree-growth?variability making traditional age-dependent?growth?models inapplicable. Estimating site productivity is ye...
Effects of Long-Term Successive Rotations, Clear-Cutting and Stand Age of Prince Rupprecht’s larch (Larix principis-rupprechtii Mayr) on Soil Quality
soil quality successive planting generation stand age clear-cutting Larix principis-rupprechtii Mayr
2024/2/28
A decline in soil quality is a major factor contributing to the degradation of forest ecological function. Vegetation plays a vital role in maintaining soil quality; however, the influence of plantati...

Monkey See Monkey Do Depending on Age Experience Efficiency
2017/7/21
Wild capuchin monkeys readily learn skills from each other — but that social learning is driven home by the payoff of learning a useful new skill. It’s the first demonstration of “payoff bias” learnin...
