Lake Louise? Very nice indeed. Stunning mountains. But have you turned around to peer into the alpine forest? Even the very edge of the forest is full of botanical treasures, such as this lovely pink flowering mountain cranberry and juicy red bunchberry. open.substack.com/pub/botanica...
Sphagnum mosses are bog-builders, #lichens are 'bog-killers'. Thick lichen mats cover large areas of northern #peatlands. Apart from being food for caribou, what is their role in peatlands? For more on my research into lichens as 'bog-killers', see Peatpedia: open.substack.com/pub/peatpedi...

Tropical #peatlands are ancient and diverse ecosystems. Vast watery peat #swamps dominated by tall palms and hardwood trees, coastal peat-forming #mangroves and marshes, and mountain Sphagnum bogs. 📢My new post on Peatpedia introduces these tropical wetlands. open.substack.com/pub/peatpedi...
I'm looking for a post-doc to work on the interaction between past hydrological changes and vegetation in a disturbed peatland, using paleoecological and modelling approaches. The post-doc duration is 18 months and start date is any time before Jan 2027. DM if you are interested / have questions! 🌿🧪
Patterned #peatlands are the cathedrals and pyramids of the natural world. Ancient architectural gems that have formed and thrived in vast watery landscapes for many thousands of years without human intervention. See Peatpedia for more: open.substack.com/pub/peatpedi...
Happy World Peatlands Day! On June 2 we shine a spotlight on the world’s bogs, fens, and swamps. This is really wonderful, but I think #peatlands deserve more attention! So, I started Peatpedia! Where the spotlight is always on these ancient ecosystems. peatpedia.substack.com #WorldPeatlandsDay
📢New on Peatpedia! A new series of brief intros to the biodiversity of #peatlands around the world, focusing on the botanical. Starting with two shrubs found in northern peatlands - Bog rosemary and Bog laurel. open.substack.com/pub/peatpedi... #BiodiversityDay #biodiversity #botany #bogs
Day 1 of Canadian Geophysical Union meeting in Halifax, NS complete! I presented initial results of a new study with several co-authors and contributors, showing that ~80% of planned major industry projects across Canada have #peatlands within a 2km buffer. More to come! @cgu-ugc.bsky.social
Where are the world's bogs, fens, and swamps? Are there peatlands still waiting to be mapped within the dense tropical forests of the Amazon and Congo? 🌎 Mapping #peatlands is a global challenge. For more, see my new post on Peatpedia: open.substack.com/pub/peatpedi...

On 8th May, our coffee morning is in collaboration with @bes-peatlandsgroup.bsky.social group! Get excited about learning how peatlands and wetlands are affected and how they can help fight climate change! When and where: 10-11 am GMT 8th May on Zoom Register here: us06web.zoom.us/meeting/regi...
Water brings #peatlands to life. Water is needed for peat soils to form and build up over time, and to sustain the resulting carbon-rich ecosystems. These large peaty water stores are important for water security and climate resilience, but they are undervalued. open.substack.com/pub/peatpedi...

While there is room for industrial carbon removal (CDR) and CCS as part of our actions to reduce GHG emissions, we must not forget the importance of maintaining existing land carbon stores and sinks, including #peatlands. #CdnPoli #CarbonCapture #ClimatePolicy open.substack.com/pub/peatpedi...
New paper alert! 🚨 Our new study shows that massive lakes in the Congo Basin are outgassing millennial-aged carbon. This challenges the idea that lake CO₂ only comes from modern vegetation. www.nature.com/articles/s41... Thread below! 🧵👇
Millennial-aged peat carbon outgassed by large humic lakes in the Congo Basin - Nature Geoscience
Two major humic lakes in the Congo Basin emit ancient carbon from nearby peatlands into the atmosphere, as shown by the isotopic signatures of their carbon pools.

📢Feb 2 is #WorldWetlandsDay! A day to celebrate the world's wetlands, including bogs, fens, and swamps. Many Ramsar sites are #peatlands but there are large gaps in global cover. For more on this issue, and on peatlands and @ramsar.org, see my new Peatpedia post: open.substack.com/pub/peatpedi...

Good eg of GenAI policy here. I agree! "...expertise lies within people, and that we cannot remove people from the equation without removing the expertise as well. Assuming that we can replace our colleagues with a statistical model trained on their knowledge can never lead to meaningful work."
Last week, during the lab meeting, we adopted a position statement (and lab rules) on the use of generative AI. epic-biodiversity.org/generative-ai/ In a nutshell: "The use of GenAI is disallowed-by-default", but we also go to great length to justify why.

Always use the mic at a conference even if you’re loud. People who can’t hear you *can’t hear you * when you ask if you can hear them in the back. Some of us went to one too many hardcore shows in our youth without ear plugs and our hearing ain’t what it used to be 🥺 #SICB2026
You have probably heard that our mossy northern #peatlands are carbon-rich, but did you know they are also berry-rich? I'm exploring the truly scrumptious berry bounty provided by northern peatlands on Peatpedia, including taste tests! First up, #cranberries! open.substack.com/pub/peatpedi...
Stuart Brooks helped move peatlands from the policy margins to a climate and biodiversity priority. A geographer by training, he built restoration standards, aligned practice with policy at major trusts, and as founder of the IUCN UK Peatland Program shaped protections still guiding work today.

Constructive reviews are so important for improving a paper. Rushed reviews that skip over potential issues often result in poorer quality publications, despite the peer review process. Ive been in this situation as author, coauthor & reviewer, wondering whether reviewer 3 even read the paper!
In my first Editorial as Associate Editor for @conphysjournal.bsky.social, we help combat this lack of training by providing some "tips and tricks" for writing constructive peer reviews, based on our collective experiences as editors for multiple scientific journals.
Google suggests the Congo is the world's largest #peatland. This is wrong! For details of the world’s largest peatland complexes, & as a ref for anyone wanting to avoid error-ridden AI search tools, I have manually searched the available literature. See Peatpedia for the results: lnkd.in/gTi32rGX

This took me back! 📚 I remember photocopying the most relevant journal pages (reduced size, so it cost less! My poor eyes...) so I could go back to my college room to study. Because I didn't want to live in the library. And so I could have a decent cup of tea while reading ☕️ 📚📚📚 Research was slow...
Then to the stacks. Journal web pages didn't exist. Everything was in hard copy. So you went to the library shelves to find the volume you needed and looked at it on paper. Sometimes this meant going to a different library.
Excited to share the first publication from my PhD work on swamps! We conducted a synoptic study of 12 swamps across southern Ontario looking at carbon pools and fluxes. doi.org/10.19189/001...
