Greening‐Induced Biophysical Impacts Lead to Earlier Spring and Autumn Phenology in Temperate and Boreal Forests

Earth's Future
Tree phenology, the timing of periodic biological events in trees, is highly sensitive to climate change. Previous studies have indicated that forest greening can impact the local climate by modifying the seasonal surface energy budget.

The Acadian Phenocam Network: Monitoring leaf and radial growth phenology to anticipate climate change impacts on forests

The Forestry Chronicle
Climate change is advancing leaf emergence in the spring and delaying leaf senescence in the fall. This extended leafing period may increase tree radial growth, with large potential impacts on wood supply and carbon sequestration, but empirical evidence ...

Shifting leaf fall phenology disrupts ecosystem function

Current Biology
Leaf litter fall and processing in temperate streams is one of the most pervasive resource subsidies and ecosystem functions globally.1,2,3 These subsidies are highly seasonally structured, yet their phenologies are shifting with climate change due to alterations of leaf senescence with global warming.4,5,6 As phenology and phenological changes are ...

Independence of stem and leaf hydraulic traits in six Euphorbiaceae tree species with contrasting leaf phenology [PDF]

Planta, 2009
Hydraulic traits and hydraulic-related structural properties were examined in three deciduous (Hevea brasiliensis, Macaranga denticulate, and Bischofia javanica) and three evergreen (Drypetes indica, Aleurites moluccana, and Codiaeum variegatum) Euphorbiaceae tree species from a seasonally tropical forest in south-western China.

Assessing plant water status: Part 2 – Non‐destructive and remote sensing approaches

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Precise, real time and non‐destructive assessment of plant water status is important for advancing plant physiological understanding, optimizing water usage, improving crop resilience and supporting precision agriculture in the face of increasingly variable climatic conditions.

Evaluating Remotely Sensed Phenological Metrics in a Dynamic Ecosystem Model

Remote Sensing, 2014
Vegetation phenology plays an important role in regulating processes of terrestrial ecosystems. Dynamic ecosystem models (DEMs) require representation of phenology to simulate the exchange of matter and energy between the land and atmosphere.

Plant phenology, leaf traits and leaf litterfall of contrasting life forms in the arid Patagonian Monte, Argentina [PDF]

, 2008
Question: Do coexisting plant life forms differ in overall phenology, leaf traits and patterns of leaf litterfall? Location: Patagonian Monte, Chubut Province, Argentina. Methods: We assessed phenology, traits of green and senesced leaves and the pattern

Phyllocephalum keralense (Asteraceae) a new species from southern Western Ghats of Kerala, India

Nordic Journal of Botany, EarlyView.
A new species of Phyllocephalum is described and illustrated from Palakkad district of Kerala, India. The new species shows similarity to P. rangacharii but differs with respect to key floral traits, viz. ovoid shape of the capitula, involucral bracts in 3 series, inflated receptacle and ovoid 6‐ribbed ovary with 5–6 densely barbellate pappus setae ...

Tetrataenium paikadae (Apiaceae), a new species from the Western Ghats, India

Nordic Journal of Botany, EarlyView.
A new species, Tetrataenium paikadae C.Rekha, Manudev & Prasanth (Apiaceae), is described from the State of Kerala, India. The new species is characterised by its hirsute to hispid stems, broadly ovate or rounded leaflets, long petioles with hirsute leaf sheaths, tomentose rays, symmetric flowers, ovate‐lanceolate involucel bracteoles, and mericarp ...
