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!

🏔️Plant communities along Swiss mountain roads are warming: species are shifting upslope, but low cover of gained and lost species masks the species turnover. Presence-only models reveal clear thermophilization signal in just 10 years🧪🌎

🌡️ 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…

🌿Liana diversity, abundance and basal area were influenced mainly by tree species richness, precipitation and soil nutrients. Liana diversity and density were positively associated with precipitation 🧪🌎

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🧪🌎

Nitrogen fertilization reduces C and N loss during late stage necromass decomposition in soil. The strength of this effect varied with necromass species but was unexpectedly unrelated to melanin content. 👉 buff.ly/CDjHmFd

🔎 Recent study suggests that long-term nutrient enrichment may have a greater impact on community composition than diversity across multiple trophic levels, and these changes in community composition can have broad implications for ecosystem functions. 👉 buff.ly/mOVKf7n
