New preprint synthesising 103 studies on tree species identification from aerial imagery identifies core gaps. Highlights need for cross-biome standardised curation, multimodal fusion, automated workflows, and advanced model architectures for scalable species mapping. eartharxiv.org/repository/v...

Biodiversity and climate strongly shape forest resilience after multi-year droughts, but after accounting for the human footprint, biodiversity’s contribution is consistently and strongly negative 🧪 www.nature.com/articles/s41...

Our new research shows that megadroughts negatively impact #forest #resilience. Managed forests had lower resilience than undisturbed forests, especially in boreal regions. This underscores the importance of mitigating human pressure for maintaining forest resilience. www.nature.com/articles/s41...

Paper out!🌳🐾Vital role of human footprint in altering forest resilience after disturbances. Forest resilience anomalies after extreme droughts relate to species richness positively or negatively, but when human pressure is included, its interaction with species richness diminishes forest resilience.

This makes science not really credible. I see nevertheless that approaches such as the ones of Zhu et al are important - as micro- and nanoplastics are likely a global threat. But we - the scientists- need to put our results into a realistic context - this is our core responsibility.

This paper is a perfect example how trying to get newspapers-citable into the focus of a paper invalidates the really important findings (microplastics can reduce photosynthesis but we do not know how this might scale to our ecosystems - just because we have no data at all.

Just imagine you go with machine learning from scarce lab data with almost no information on plastic pollution under real world conditions to crop and fishery yield losses as a result of that given pollution. I acknowledge that this is a first step - but you need to name the shortcomings.

They (1) extrapolate plastic impact measurements on photosynthesis under controlled and highly artificial conditions to the real world (2) without valid data on global plastic pollution and (3) without any baseline for their model.

We still feel that this later statement in their response letter is not congruent with the alarming statements in the original text: „These findings underscore the urgency of integrating plastic mitigation into global hunger and sustainability initiatives“ which seem to be targeted to press coverage

In their response (www.pnas.org/doi/10.1073/...) some authors of the original paper state that „[they] believe it is scientifically sound and responsible to use currently available—albeit limited evidence—for preliminary assessments and to stimulate broader scientific and policy dialog“

This is our critical assessment of www.pnas.org/doi/10.1073/... These authors claimed that they can calculate quite exact MP-induced real world global photosynthesis losses translating in a reduction of 22.15 to 115.73 MT·y−1 in main crop production and 0.32 to 7.39 MT·y−1 in seafood production.

"Towards a global understanding of tree mortality" in @newphyt.bsky.social It was fun and productive participating in this review by the International Tree Mortality Network nph.onlinelibrary.wiley.com/doi/10.1111/...

Towards a global understanding of tree mortality - @newphyt.bsky.social ; @treemortality.bsky.social : https://nph.onlinelibrary.wiley.com/doi/10.1111/nph.20407

Integrating forest inventories with remote sensing and modelling is needed to better understand tree mortality. A global effort should promote equitable collaborations, empowering scientists from less wealthy regions. @treemortality.bsky.social nph.onlinelibrary.wiley.com/doi/10.1111/...

🌳 🧪New research suggests less frequent rainfall may lead to earlier leaf senescence through increased drought stress and acclimation mechanisms. Important implications for understanding climate change impacts on vegetation cycles! #ClimateScience #Ecology: www.nature.com/articles/s41...

There are so many signs that #climate change is severely affecting #ecosystems and consequently human societies - @liangzhi-chen.bsky.social et al. showed a global increase in the occurrence and impact of multiyear #droughts. We need to act now! https://www.science.org/doi/10.1126/science.ado4245

The earth gets drier and warmer, and #megadroughts have been increasing for 40 years and will do so in the future. Substantial negative impacts on #water supply, #agriculture and all #ecosystem services are to be expected. www.science.org/doi/10.1126/...

New paper in @science.org ! Where and when did the #multiyear-droughts occur around the world? Have they become more prevailing? We identified over 10,000 such events and found that they have been increasingly occupying the terrestrial land. (1/6) www.science.org/doi/10.1126/science.ado4245

We used a morphological approach to identify #megadroughts globally over the past 40 years and applied plant-greenness indices to determine the impacts on vegetation. Megadroughts are increasing in frequency, area and intensity on the global scale.
