📣 Our paper on soil carbon response to tree planting is out in J. of Env. Management:

🌲 Temperate grassland conversion to conifer forest destabilises mineral soil carbon stocks

Open access ➡️ tinyurl.com/3krerb92

A short thread ⤵️

Conceptual diagram representing hypothesised mechanisms leading to observed differences in SOM pools between grasslands and coniferous forests. Differences in flux sizes are represented by varying arrow widths. Differences in the size of functionally distinct litter and SOM pools are represented by varying icon numbers.

📢 Funded PhD opportunities for UK candidates in beautiful Edinburgh. Get in touch if you're interested in a PhD on understanding the mechanisms of soil carbon cycling and the role of microbes. We work in different ecosystems: peatlands, forests and agricultural soils. Please repost/spread the word.

Poster showing the following text: PhD in microbial mechanisms of soil carbon cycling. Soil microbes shape the global carbon cycle in life and death. We study the effect of aboveground land management on belowground soil carbon cycling processes. We aim create a scalable understanding of microbial processes from single cells to populations to communities to ecosystems. Pictures with text: peatland restoration, sustainable agriculture and woodland regeneration.

We show that how you plant tree species (not just which) can significantly boost forest functioning.

If you use "Greetings of the day!", "distinguished speaker", or "your valuable submission" in your emails, my new bespoke spam filter will mark is as read and delete it. Works like a charm for now.

Introducing New Zealand's latest Bug of the Year- the magnificent Ngāokeoke / Velvet Worm!

NZ has two genera: one lays eggs (Ooperipatellus, 1st photo) and another gives live birth (Peripatoides, 2nd). They also deposit sperm which burrow through their partner's skin, but that's another story! 🧪

A photograph of a velvet worm - an orange and purple-patterned invertebrate composed of many soft segments and tiny spined legs. The velvet worm has long, segmented antenna and a pair of organs on its head which squirt glue for prey capture.

We're all on tenterhooks waiting for the results to be announced tomorrow for the NZ Bug of the Year competition!

Here's a few of my favourite contenders. Now voting is over I'll admit I have been quietly rooting for the velvet worm too - they're amazing animals!

Good luck #TeamGiantSpringtail!

Women are credited less in science than men - Nature

The difference between the number of men and women listed as authors on scientific papers and inventors on patents is at least partly attributable to unacknowledged contributions by women scientists.

I would be a bit more nuanced, but it's not far off. If one only cares about carbon, planting trees can sometimes be useful, though not as much as we think, and it can be even detrimental in carbon-rich soils (peat/peaty soils, tundra, etc).

François-Xavier Joly @fxjoly.bsky.social · Jan 22

Hard to say as this likely depends on various factors (climate, starting soil C stock, plant community), but encroachment from EM-associated trees might trigger a similar effect, albeit perhaps not of the same magnitude. Further research is needed to verify the external validity of our findings!

François-Xavier Joly @fxjoly.bsky.social · Jan 21

This effect likely depends on various factors (climate, starting soil C stock, plant community), but ectomycorrhizal-associated deciduous trees might trigger a similar effect, albeit perhaps not of the same magnitude. Further research is needed to verify the external validity of our findings.
