...depending on the state transitions that occur between vegetation types. Ominous. At Lake Ohrid Albania, °C had already been at normal level for 1000 years when tree pollen caught up and forest had returned. 1000 years for full "state transition" from steppe to forest! Thats how slow 🌱🐝🐭🐦🐺migrate.

Happy to report that I’ve started my pollen extraction 😁
Great workshop & field visit on wetland restoration of heavily degraded peatlands in Sudbury (Ontario) led by @mercury-ecohydro.bsky.social
Happy to share the first article published in "Catena" by my post-doc Laura Gedminienė about the climatic trends in the South Baltics during the end- Pleistocene and Holocene. [free access for 50 days] kwnsfk27.r.eu-west-1.awstrack.me/L0/https:%2F... 🧪 #Paleobio ⚒️ #Geology #Climate
Hi Bluesky! 👋 I'm a researcher interested in plants, people and climate changes in the past, present and future - with a particular focus on Araucaria forests in Brazil and elsewhere. I also run the 3D Pollen Project (3dpollenproject.wixsite.com/main) because pollen is cooler than you think!
The ultimate Late #Glacial non-analogue community from southern Canada ca. 16,000 BP. Oroarctic elements: Dryas cf. integrifolia and cf. Arenaria (lower 2 grains) and boreal white spruce (upper left) and black spruce (upper right). #paleoecology #pollen #paleoclimate

Having some #AGU2024 FoMo this year but can’t leave the family again. At least our (Drs Ellie Goud Pete Whittington Peter Beckett @florinp.bsky.social & @nbasiliko.bsky.social) research on restoring critical #peatland functions in heavily metal polluted landscapes is still there youtu.be/-smiKnf-WU8

An offering to the Mother Fen who let us tell her story. Poor fen north of Sudbury impact crater, Ontario. #peatlands
Abies balsamea pollen ca. 9500 BP - southern Ontario (Canada)
Palynology is where a core is taken of a bog. Pollen is laid down annually on the bog & survives protected in the moss as it grows. The core is sampled at intervals & inspected under a microscope & data extrapolated, carbon dated & read & vegetation identified
Welcome to our palaeo/paleofeed! If you are a paleoecologist or a fan of lost worlds, time traveller, or just a lover of Earth’s history, this feed is for you 💕 As holidays are coming up soon here is a proper paleobell 😀
Saxifraga oppositifolia pollen - 18,000 BP from the former Laurentide ice margin, southern Ontario.
Interested in ponds and greenhouse gas emissions? I'll shortly be advertising a PhD at University of Liverpool with the title: "How do fish affect greenhouse gas emissions from small waterbodies?"

Hey #GHG folks (and R enthusiasts) - check this out: github.com/Qepanna/GoFl... Apparently user friendly and great for students
Thank you Bluesky for having me here! To start, thought of sharing a shot of sky magic - North Bear Alvar - Ontario, Canada
