3) Treating all fine roots the same (=ignoring root orders or functions) likely decreases the explanatory power of current trait-based approaches. If we want to view the fine root trait space more holisticly, traits related to trasnport need to be integrated.

1) We need to collect more trait data reflecting transport functions (conductivity etc).
2)Approaches based on root orders are not perfect (because functioning of different orders is species-specific, see e.g. the high mycorrhization of 'transport roots'), but still provide higher resolution.

The functions of transport roots (transporting and storing resources) are not well reflected with these traits and hence traits reflecting absorption capacity or rates do not matter as much in transport roots. So what does that mean for root functional ecology?
comment in response to
post
Not quite!
With higher root order, traits but also the function of the roots change. However, many of the commonly measured fine root traits are proxies of nutrient uptake, soil exploration or mycorrhizal collaboration (all of which mostly happening in lower order roots).

Traits of absorptive fine roots that were related to a 'do-it-yourself' strategy (high specific root length, low diameter, low mycorrhization) were associated with higher tree growth. For transport fine roots, these traits did not relate to growth rate. Does that mean, transport roots don't matter?
comment in response to
post
To account for heterogeneity of the roots based on branching hierarchy, fine roots were separated by order, differentiating between absorptive fine roots (order 1-3) and transport fine roots (order 4-5).

With many colleagues and students of @agwirthweigelt.bsky.social (incl. @fonsvanderplas.bsky.social and others not on Bsky), we used the research arboretum 'ARBOfun' near Leipzig to measure root traits and tree growth.

For a quick literature search, google scholar is more convenient anyway but I guess the issue with WoS are problematic for many other aspects (systematic literature reviews based on citations, H-index in hiring committees etc, )? Or are we not using web of science anymore anyway?
comment in response to
post
It seems that WoS is not working for cross-reference of citations and authorships, features that are some of the main use-cases of the platform, right?
comment in response to
post
I have requested corrections for these entries multiple times and was happily notified by WoS within a few days that the corrections were made, yet there was never any change done!

One citation of 'Bergmann et al.' in my paper is linked to a paper by 'Berg et al.' (in a completely different discipline!) in WoS and my citation is therefore not listed and counted as a citation of the Bergmann paper.

It’s curious how you accept physical science but deny social science. You’re willing to listen to scientists on global temperature but you think you know better when it comes to effective communication.
If you’re willing to reconsider, start here; then find my book Saving Us in your local library.

This was a great collaborative project, including @joanabergmann.bsky.social, @eisenhauerlab.bsky.social, @a-h-b.bsky.social and many other great co-authors who are not (yet) on BlueSky!

So in short (and simplified!): Root functional strategies determine the (functional) composition of fungal communities in the soil but plant diversity/productivity determines the absolute fungal biomass.
comment in response to
post
Plant diversity only shows minor effects on the composition and diversity of soil fungi.
The absolute abundance/biomass of soil fungi, however, is strongly dependent on plant diversity, likely because of the increased (root) biomass production in diverse plant communities.

At the same time, 'outsourcing' communities also relate to less diverse and less abundant pathogen communities in the bulk soil! (While we cannot resolve the mechanisms, we compiled reasoning and literature for trait-fungi relationships in a previous New Phytologist paper doi.org/10.1111/nph....)
comment in response to
post
Different root functional strategies of the communities also strongly affect the diversity and relative abundance of soil fungal guilds. Specifically, 'outsourcing' communities (high mean root diameter, potentially more collaborative with arbuscular mycorrhiza) show more diverse AMF communities.
comment in response to
post
We show that trait coordination from community root traits closely resembles the species-level root economics space, suggesting that plant communities also differ in their collaboration with mycorrhiza and their conservation of resources.

In experimental grassland communities of the @jena-experiment.bsky.social, we measured root traits at the community level, i.e. without species separation, sequenced fungal communities and measured respiration and fatty acids from bulk soil.
comment in response to
post
We tested how fine root traits, and their coordination at the community level, relate to the diversity and composition of fungal guilds and fungal abundance in the soil.

Ellen Sandell MP gave one of the most straightforward reasons for scientists as advocates that I've heard so far: The fossil fuel industry is eagerly talking to MPs, so scientists shouldn't hold back from talking to politicians too. We need to balance out the oil self-interests. #ESAus2024 🧪🌏
