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 ...
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 ...
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...
Tree health influences diameter growth along site quality, crown class and age gradients in Nothofagus forests of southern Patagonia
Nothofagus pumilio annual diameter increment
2015/4/24
We examined the influence of tree health on annual diameter increment of trees along gradients in stand site quality, crown classes and tree age in Nothofagus pumilio forests of Southern Patagonia. He...
Preliminary study on phloemogenesis in Norway spruce: influence of age and selected environmental factors
cambium environmental factors influence of age light microscopy Norway spruce (Picea abies) phloem formation
2015/3/27
The process of phloem formation in Norway spruce (Picea abies [L.] Karst.) was analysed during the growing season 2009 in Rájec-Němčice locality (Czech Republic). The research series consisted of...
Trees put on weight faster and faster as they grow older according to a new study in the journal Nature. The finding that most trees’ growth accelerates as they age suggests that large, old trees may ...
Comparison of Changes in Organic Matter Dynamics due to Stand Age between Artificial Japanese Cedar (Cryptomeria japonica D. Don) Forests and Japanese Cypress (Chamaecyparis obtusa Sieb. et Zucc.) Forests
