Alas I was asked to give evidence but cannot attend in that session - in Finland the whole week without easy Wifi access. Keep me posted on how it goes!

Can you add me too? Many thanks

How odd. Try these from jobs.ac.uk instead. Research tech: www.jobs.ac.uk/job/DLK891/s... Senior Research Associate (postdoctoral): www.jobs.ac.uk/job/DLF659/s...

Note, this is the specific report to which the OEP refer, on nutrient export from diffuse agricultural sources. You'll find a link to it on the bottom of the OEP page.

They are written throughout the report. The Farmscoper model only simulates nitrate. This represents fertiliser sources of N pollution well, but misses the organic N loading from livestock, which is key in the majority of catchments in the N and W of England, where it is the dominant system.

I chaired the Water Targets Advisory Group that advised on the EA2021 targets. Targets for reduction of pollutants from agriculture were very clear. 40% reduction in nitrOGEN, phosphorus and sediment. The report refers to nitrATE. They are not one and the same thing. Disappointing.

You missed new followers who are 'Here looking for a God-fearing woman' and similar.....since when was Bluesky a dating site?!

Interesting! I'll look out for your progress with this. Our focus is investigating how DOM is used as an (often) preferred nutrient resource for freshwater biota. We like using these mosses as they are ubiquitous (in UK freshwaters) and don't root so are an easy win for mesocosm studies.

Snap...or nearly! What are you investigating? We are using dual-labelled isotope dosing in stream mesocosms on our NERC QUANTUM programme (quantumfreshwaters.org) to investigate rates and mechanisms of DOM uptake by the biota including epilithon, aquatic mosses and snails. 🧪

Loving mine. Freshwater whisperer with a secret skill of 'keeping a straight face while talking about cow poop'. Alarmingly accurate....though I do like the pub analogy!

Write the easy bits first. Maybe the site description, methodologies and approaches. Think about the paper as a coil/spiral - you start in the middle and you work your way out. Often the introduction is the most difficult to write, but you don't have to write it first!

Hi James. Nice to see you over here. Have you found the starter packs yet? Great invention!

Landed on Wednesday. Looking up people whose work interests me. Aren't the starter packs a great idea!

Can't comment on the first of these but YSI Exo2 is good for one 3-5 yr programme. After that costs to recalibrate are prohibitive, and we have now moved over to Aquatrolls. 🧪

I'm on full time research for 5 yrs (ERC Adv. Grant) but I taught until this summer. I always told my students they couldn't consider themselves educated if they didn't read Leopold, and gave them this quote after lectures where they came out slightly stunned about the true state of the environment

Looking forward to hearing it! My excuse is that I've been ill all week..... and we have been incredibly busy with our field experiments, only finishing the first of our 8-day stream isotope dosing experiments last weekend! Sample prep for analysis currently underway....and breathe!

Yes..... all I have to do is write the presentation today! @jmbecologist.bsky.social presenting too, I think.

We are hoping to capture the dynamic riverine flux of nutrients, ecotoxins, pathogens and dissolved organic matter from livestock farming during this storm event, under our NERC QUANTUM programme ..... but wondering about the naming of it and how that's going look in our science papers!🧪

I've chaired one of these in the past and attended several more. They are excellent fun and quite unlike other conferences. There's more time to really get into the science and to have meaningful discussions with other attendees. Strongly recommend!

Me! Hoping to launch my new projects here too, in the next few months, and drag over my NERC QUANTUM project tweets too... or just start afresh here!

Hi Timothée I've just moved here from Twitter. Could you add me to the Science🧪 feed? You can find me here research-information.bris.ac.uk/en/persons/p... here g.co/kgs/gy6DcmG and here: orcid.org/0000-0003-16... 🙂
