Height does not impair the hydraulic system of the tallest tropical Dipterocarp trees www.science.org/doi/10.1126/... - good to see our #MetabolicScalingTheory predictions we made for scaling of hydraulic resistance and xylem anatomy hold up in some of the tallest trees #allometry #megabiota 🧪🌾🌐

Height does not impair the hydraulic system of the tallest tropical Dipterocarp trees

Half of the aboveground biomass in forests is stored in a disproportionately small number of very tall trees. These giants are predicted to be more vulnerable to drought-induced damage because height ...

New paper out! 🖨️ Glad to be part of this study, out in Science Advances: "Emergent patterns of island biodiversity in the Anthropocene" www.science.org/doi/10.1126/... Much of what looks natural in island biodiversity is a legacy of human impacts going back millennia. See main findings 👇🧵 (1/8)

Emergent patterns of island biodiversity in the Anthropocene

Human impacts substantially affect our ability to detect and understand natural biodiversity patterns.

On commence déjà à percevoir les effets de + 1,0 oC. Pas besoin d’attendre d’être à +1,5 oC en moyenne (dépassé en 2024) pour agir.

Tree diversity is changing in the Amazon and Andes. Belen Fadrique leads our analysis in @natecoevo.nature.com w/ 400 plots + 40 years of RAINFOR records. www.nature.com/articles/s41... Hot, drier, more fragmented forests are losing species. Many in the Andes + western Amazon are gaining them.

TIL about a memorial ceremony in Iceland in 2019 to mark the end of a glacier, changing the place name from Okjökull to Ok (jökull = glacier). Uncompromising wording on the bronze plaque: "This is to acknowledge that we know what is happening and what needs to be done. Only you know if we did it".

Bronze plaque saying "A Letter to the Future. Ok is the first Icelandic glacier to lose its status as a glacier. In the next 200 years all our glaciers are expected to follow the same path. This monument is to acknowledge that we know what is happening and what needs to be done. Only you know if we did it. August 2019. 415ppm CO2"

Extra CO2 stimulates #photosynthesis of trees and reduces water losses through transpiration. But does that stimulate growth of #tree stems? Our paper today in NatClimateChange led by Quan Zhang uses theory & data to show that strong growth stimulation is unlikely.🌎🌐🍁 www.nature.com/articles/s41...

Increased efficiency of water use does not stimulate tree productivity - Nature Climate Change

The authors theoretically delineate the maximal increases in tree growth that can be expected from increases in plant intrinsic water-use efficiency, which increases with rising CO2. They highlight en...

in "General laws of biodiversity: Climatic niches predict plant range size and ecological dominance globally", we provide key insights into species’ vulnerability to environmental change and the processes that structure biodiversity at global scales. www.pnas.org/doi/10.1073/...

General laws of biodiversity: Climatic niches predict plant range size and ecological dominance globally | PNAS

A longstanding question in ecology asks whether or not species that achieve large geographic ranges also have large climatic niche breadths. Using ...

Another new species discovered in Peru, in Parque Nacional Yanachaga-Chemillén. The type specimen of 𝑆𝑜𝑙𝑎𝑛𝑢𝑚 𝑠𝑡𝑒𝑙𝑙𝑎𝑡𝑖𝑐𝑎𝑙𝑦𝑐𝑖𝑛𝑢𝑚 was collected by Marco Cueva, Abel Monteagudo, Antonio Peña and colleagues working in the Yanachaga RAINFOR montane forest plots. doi.org/10.3897/phyt...
