Dr Pierre Mariotte @pierremariotte.bsky.social · Dec 26

About me. I originate from a low-income loving family of farmers/foresters and was born in a remote area, covered by #forest, #grassland and #agriculture fields. I am the 1st in my family to hold a #PhD degree. With passion and work, all #dreams come true. (Photos: Mom, Dad & me).

Jane Goodall has been a role model for generations of women scientists and ecologists. She taught us that we can follow our passion beyond the roles society assigns us — that we can be compassionate while still being ambitious. She opened the path and paved the way with elegance. Forever grateful!

🌡️ Native grassland plants fare better under drought than introduced plants. However, this advantage is mitigated when other global change drivers, such as elevated temperature, increased nutrients, and elevated CO2, are considered alongside drought🧪🌎

Native plant species exhibit consistent drought advantage over introduced species until additional global change drivers are included: A grassland meta‐analysis

We examined how drought, predicted to increase under climate change, influences native and introduced plants in grasslands using a meta-analysis. Native plants fared better than introduced plants…

Extremely proud of Eileen Enderle for publishing her second PhD paper in @journalofecology.bsky.social !!

She shows that the impact that drought has on plant-soil feedback is mediated by soil bacterial and fungal communities.
besjournals.onlinelibrary.wiley.com/doi/full/10....

Drought legacy effects on plant growth and plant–soil feedback are mediated by soil microbial communities independently of root exudates and root litter

The results show that drought indirectly restricts plant growth, which is not mediated by root exudates or root litter, but through altering microbial biomass and community composition. These finding...

🌱Shading plays a dominant role in recruitment, but stochastic factors and seed limitations can alter outcomes over time. Understanding how these forces interact is key to predicting vegetation patterns and potential shifts in dryland ecosystems🧪🌎

Finally! 🤩 Our position piece: Against the Uncritical Adoption of 'AI' Technologies in Academia:
doi.org/10.5281/zeno...

We unpick the tech industry’s marketing, hype, & harm; and we argue for safeguarding higher education, critical
thinking, expertise, academic freedom, & scientific integrity.
1/n

Abstract: Under the banner of progress, products have been uncritically adopted or
even imposed on users — in past centuries with tobacco and combustion engines, and in
the 21st with social media. For these collective blunders, we now regret our involvement or
apathy as scientists, and society struggles to put the genie back in the bottle. Currently, we
are similarly entangled with artificial intelligence (AI) technology. For example, software updates are rolled out seamlessly and non-consensually, Microsoft Office is bundled with chatbots, and we, our students, and our employers have had no say, as it is not
considered a valid position to reject AI technologies in our teaching and research. This
is why in June 2025, we co-authored an Open Letter calling on our employers to reverse
and rethink their stance on uncritically adopting AI technologies. In this position piece,
we expound on why universities must take their role seriously toa) counter the technology
industry’s marketing, hype, and harm; and to b) safeguard higher education, critical
thinking, expertise, academic freedom, and scientific integrity. We include pointers to
relevant work to further inform our colleagues.

Figure 1. A cartoon set theoretic view on various terms (see Table 1) used when discussing the superset AI
(black outline, hatched background): LLMs are in orange; ANNs are in magenta; generative models are
in blue; and finally, chatbots are in green. Where these intersect, the colours reflect that, e.g. generative adversarial network (GAN) and Boltzmann machine (BM) models are in the purple subset because they are
both generative and ANNs. In the case of proprietary closed source models, e.g. OpenAI’s ChatGPT and
Apple’s Siri, we cannot verify their implementation and so academics can only make educated guesses (cf.
Dingemanse 2025). Undefined terms used above: BERT (Devlin et al. 2019); AlexNet (Krizhevsky et al.
2017); A.L.I.C.E. (Wallace 2009); ELIZA (Weizenbaum 1966); Jabberwacky (Twist 2003); linear discriminant analysis (LDA); quadratic discriminant analysis (QDA).

Table 1. Below some of the typical terminological disarray is untangled. Importantly, none of these terms
are orthogonal nor do they exclusively pick out the types of products we may wish to critique or proscribe.
