We found that when temps hit 30°C+, C3 plants start struggling - their carbon metabolism gets disrupted, they burn through sugar stores faster, and even their isotope signatures change.
Meanwhile C4 plants? They're basically chilling like "this is fine" 😎

Africa’s forests have joined the Brazilian Amazon and Australian forests in becoming carbon sources rather than sinks. Around 2010 the previous storage of our carbon emissions flipped, mainly through deforestation and degradation.

🎄 ANNOUNCEMENT: R Package Development Advent Calendar 2025! 🎄

Starting December 1st, I'm launching a 25-day journey through modern R package development. here's why you should follow along 🧵

#rstats #RPackageAdvent2025 #OpenSource
A festive digital illustration features the blue R logo wearing a red Santa hat with white trim on the left. To its right stands a green Christmas tree made entirely of curly braces arranged in a triangular shape. White and light-blue %>% pipe symbols float across a dark blue, starry background like snowflakes. A speech bubble above the R logo says “Ho Ho Ho! 📦” in red text. At the bottom, white text reads: “R Package Development Advent Calendar 2025” and below it, “25 Days of Coding Magic • Dec 1–25.”

Reptiles confined to islands are facing a double jeopardy 🦎

New research from @ricardonature.bsky.social shows that 30% of island reptiles are threatened with extinction (compared to 12.1% of reptiles overall) - but only 6.7% of reptile-focused research since 1960 has studied them 👇

Our new paper in Ecology Letters, led by Jan Divíšek, shows that non-invasive alien plant species that successfully establish within local plant communities tend to resemble the resident native species. In contrast, invasive alien species usually differ from native plants.

We wrote the Strain on scientific publishing to highlight the problems of time & trust. With a fantastic group of co-authors, we present The Drain of Scientific Publishing:

a 🧵 1/n

Drain: arxiv.org/abs/2511.04820
Strain: direct.mit.edu/qss/article/...
Oligopoly: direct.mit.edu/qss/article/...
A table showing profit margins of major publishers. A snippet of text related to this table is below. 1. The four-fold drain 1.1 Money Currently, academic publishing is dominated by profit-oriented, multinational companies for whom scientific knowledge is a commodity to be sold back to the academic community who created it. The dominant four are Elsevier, Springer Nature, Wiley and Taylor & Francis, which collectively generated over US$7.1 billion in revenue from journal publishing in 2024 alone, and over US$12 billion in profits between 2019 and 2024 (Table 1A). Their profit margins have always been over 30% in the last five years, and for the largest publisher (Elsevier) always over 37%. Against many comparators, across many sectors, scientific publishing is one of the most consistently profitable industries (Table S1). These financial arrangements make a substantial difference to science budgets. In 2024, 46% of Elsevier revenues and 53% of Taylor & Francis revenues were generated in North America, meaning that North American researchers were charged over US$2.27 billion by just two for-profit publishers. The Canadian research councils and the US National Science Foundation were allocated US$9.3 billion in that year. A figure detailing the drain on researcher time. 1. The four-fold drain 1.2 Time The number of papers published each year is growing faster than the scientific workforce, with the number of papers per researcher almost doubling between 1996 and 2022 (Figure 1A). This reflects the fact that publishers’ commercial desire to publish (sell) more material has aligned well with the competitive prestige culture in which publications help secure jobs, grants, promotions, and awards. To the extent that this growth is driven by a pressure for profit, rather than scholarly imperatives, it distorts the way researchers spend their time. The publishing system depends on unpaid reviewer labour, estimated to be over 130 million unpaid hours annually in 2020 alone (9). Researchers have complained about the demands of peer-review for decades, but the scale of the problem is now worse, with editors reporting widespread difficulties recruiting reviewers. The growth in publications involves not only the authors’ time, but that of academic editors and reviewers who are dealing with so many review demands. Even more seriously, the imperative to produce ever more articles reshapes the nature of scientific inquiry. Evidence across multiple fields shows that more papers result in ‘ossification’, not new ideas (10). It may seem paradoxical that more papers can slow progress until one considers how it affects researchers’ time. While rewards remain tied to volume, prestige, and impact of publications, researchers will be nudged away from riskier, local, interdisciplinary, and long-term work. The result is a treadmill of constant activity with limited progress whereas core scholarly practices – such as reading, reflecting and engaging with others’ contributions – is de-prioritized. What looks like productivity often masks intellectual exhaustion built on a demoralizing, narrowing scientific vision. A table of profit margins across industries. The section of text related to this table is below: 1. The four-fold drain 1.1 Money Currently, academic publishing is dominated by profit-oriented, multinational companies for whom scientific knowledge is a commodity to be sold back to the academic community who created it. The dominant four are Elsevier, Springer Nature, Wiley and Taylor & Francis, which collectively generated over US$7.1 billion in revenue from journal publishing in 2024 alone, and over US$12 billion in profits between 2019 and 2024 (Table 1A).

The Canadian research councils and the US National Science Foundation were allocated US$9.3 billion in that year. The costs of inaction are plain: wasted public funds, lost researcher time, compromised scientific integrity and eroded public trust. Today, the system rewards commercial publishers first, and science second. Without bold action from the funders we risk continuing to pour resources into a system that prioritizes profit over the advancement of scientific knowledge.

The achievable carbon uptake from planting trees is much lower than previous estimates, and even lower than many nations have committed to. New paper by Wang et al. in Science. www.science.org/doi/10.1126/... 🧪🌏🌳🌲🌐
Fig. 3. Estimated mitigation potential from forestation varies with land availability assumptions. (A) Global and regional ecosystem carbon sequestration. BA19 (10), GR17 (8), and Qin24 (24) refer to respective assumptions of land potentially available for forestation. The “committed” assumption considers only national commitments, and “achievable” shows currently achievable land limited by availability defined in Qin24 (see materials and methods section M3). (B) The currently achievable mitigation potential varies among countries and income groups. Country-specific data are available in data S3 (24). Country codes and corresponding income groups can be found in table S6.

This is a local effect in addition to global heating.
