- Considering physiological acclimation to sun-shade in grapevine canopiesby Matt on 2024-07-29
Continuing CanSEE group research into photosynthetic acclimation to fluctuations in light in plant canopies, we have just published new research showing the photoprotection and photosynthetic produce stronger responses to steady than fluctuating UV radiation of the same total irradiance. Across a suite of response including antioxidant accumulation and photosynthetic sufficiency, plants that received moderate doses … Continue reading "Considering physiological acclimation to sun-shade in grapevine canopies"
- Methane emissions from trees driven by solar radiation & temperatureby Matt on 2023-12-24
Tree planting is seen as a mitigation strategy to remove greenhouse gas from the atmosphere, as trees fix carbon dioxide by photosynthesis, but trees also emit various organic compounds that act as greenhouses gases, and it is important to quantify these emissions to understand the scales of the net benefit of trees and forests against … Continue reading "Methane emissions from trees driven by solar radiation & temperature"
- Extended canopy closure under with mild autumns, and its effect on the understorey growing seasonby Matt on 2023-11-22
In a new paper just out in Agricultural and Forest Meteorology, we explore how extended canopy closure in oak and birch forests at Lammi Biological Station in southern Finland affects the growing season for common understorey forbs. The paper describes an experiment to test the effects of climate warming which may extend the length of … Continue reading "Extended canopy closure under with mild autumns, and its effect on the understorey growing season"

- The Earth is not flat. Are plants and plant canopies flat?by Pedro J Aphalo on 2022-12-30
The problem Irradiance or spectral irradiance on a horizontal plane is normally used to quantify energy or photons available for photosynthesis. Similar measurements of irradiance in narrow bands of the spectrum or spectral irradiance measurements are used to characterize radiation features perceived by plant through photoreceptors. In the case of photosynthesis this makes some sense … Continue reading "The Earth is not flat. Are plants and plant canopies flat?"
- Visit to Universidad Austral de Chileby Pedro J Aphalo on 2022-12-22
I recently visited Universidad Austral de Chile (UACh) located i n Valdivia. This trip is part of a colaboration with Daniel Calderini in a project about responses of wheat to planting density. My contribution is related to light quality in wheat canopies with plants at different spacing. I also taught an intensive doctoral course titled … Continue reading "Visit to Universidad Austral de Chile"
- The R Universeby Pedro J Aphalo on 2022-12-18
My R packages are now listed at the R universe, a new web site with a repository of packages accesible in multiple ways. It is implemented as a database rather than being static like CRAN. The R Universe seems like a good tool to not only find packages but also to monitor their health. Its … Continue reading "The R Universe"
