New insights into eastern Siberian landscape development after the Last Glacial Maximum: @Iza_bai et al. with a new study (published today) of terrestrial and aquatic #vegetation and #lake ecology changes throughout the last ~18,000 years! 🌲🏞️

FrontiersLate Glacial and Holocene vegetation and lake changes in SW Yakutia, Siberia, inferred from sedaDNA, pollen, and XRF dataOnly a few palaeo-records extend beyond the Holocene in Yakutia, eastern Siberia, since most of the lakes in the region are of Holocene thermokarst origin. Thus, we have a poor understanding of the long-term interactions between terrestrial and aquatic ecosystems and their response to climate change. The Lake Khamra region in southwestern Yakutia is of particular interest because it is in the transition zones from discontinuous to sporadic permafrost and from summergreen to evergreen boreal forests. Our multiproxy study of Lake Khamra sediments reaching back to the Last Glacial Maximum 21 cal ka BP, includes analyses of organic carbon, nitrogen, XRF-derived elements, sedimentary ancient DNA amplicon sequencing of aquatic and terrestrial plants and diatoms, as well as classical counting of pollen and non-pollen palynomorphs (NPP). The palaeogenetic approach revealed 45 diatom, 191 terrestrial plant, and 65 aquatic macrophyte taxa. Pollen analyses identified 34 pollen taxa and 28 NPP taxa. The inferred terrestrial ecosystem of the Last Glacial comprises tundra vegetation dominated by forbs and grasses, likely inhabited by megaherbivores. By 18.4 cal ka BP a lake had developed with a high abundance of macrophytes and dominant fragilarioid diatoms, while shrubs expanded around the lake. In the Bølling-Allerød at 14.7 cal ka BP both the terrestrial and aquatic systems reflect climate amelioration, alongside lake water-level rise and woodland establishment, which was curbed by t...

Traditional land use practices in #Yakutia, eastern #Siberia, may have mediated #wildfires for centuries - until these practices were prohibited 🔥
See our evidence, obtained from lake sediments, tomorrow (Monday) at #EGU24 in session BG1.1! Looking forward to meet you there!

#newResearch on Daddy-Daughter Dances, and their role in heteronormativity and stigmatization. Explicitly gendered events such as these informally exclude people without heteronormative family structures. Thanks to Ezra Temko, Emily Love, Destiny Baxter, Adam Loesch & Heidi Masching for a great article.

New #research paper just out: We simulated climate-driven #wildfires 🔥 and their impacts on forests in #Yakutia, eastern #Siberia, throughout ~20,000 years since the LGM ❄️ in the individual-based model LAVESI-FIRE 🌲

Results show stand-replacing fires decreasing larch dominance, and the occurrence of different post-fire regeneration pathways under similar fire regimes.

Evaluating growth in #Macrospondylus bollensis (#Crocodylomorpha, Teleosauroidea) in the Toarcian Posidonia Shale, Germany onlinelibrary.wiley.com/doi/fu

"juvenile, subadult and adult individuals show nearly equal growth in many areas of the body... We call this isometric growth, which is unusual in #vertebrates.”

Wow I'm delighted that #WaterfallWednesday is a thing. First #Bloomscrolling, now this.

Academics, maybe we need some pithy hashtags to increase engagement too. #MondayMethods? #WritingHackWednesday? #NewResearch...Thursday?

#SocAF on Twitter did something similar.

Summer #sea #ice in the #Arctic could melt almost completely by the 2030s - roughly a decade earlier than projected - even if humans cut back drastically on #GreenhouseGas #emissions , #NewResearch suggests. 
“We are very quickly about to lose the Arctic summer sea-ice cover, basically independent of what we are doing,” Dirk Notz, a #climate #scientist at the #UniversityOfHamburg in Germany tells the #NewYork Times Raymond Zhong

What gets Native Americans politically and civically engaged?

4 studies with 11,000+ Native Americans finds that identifying as Native was associated with engaging in get-out-the-vote behaviors and intentions to engage in civic activities in the future

Effects likely do to the recognition of the omission of their group from society and perceive greater group discrimination
