Ronnie Rattanasriampaipong @paleolipidrr.bsky.social · 21/06/2025#Temporal changes of GDGT-2/-3 over the past 190 million years suggest that ecology of ammonia-oxidizing #archaea (#AOA) changes with Earth's past #climates and #oceans.

Ronnie Rattanasriampaipong @paleolipidrr.bsky.social · 21/06/2025Here's what we found: 1) Hot spring #archaea show #thermal pattern in both cultures and env. samples. 2) #SPM and #coretops are grouped into #shallow and #deep samples using #pycnocline. Shallow = thermal. Deep = #nonthermal. 3) Paleo-lipids show patterns change thru time!! (6/10) 110
Ronnie Rattanasriampaipong @paleolipidrr.bsky.social · 21/06/20252 patterns to look for here: 1) Samples with #TEX86 should show low GDGT-2/-3 (more GDGT-3 at higher T). This is our expected #thermal pattern. 2) The opposite occurs with core-top sediments. We called this #nonthermal pattern. We investigated #GDGTs from 7 archives!! (5/10) 120
Ronnie Rattanasriampaipong @paleolipidrr.bsky.social · 21/06/2025But #archaea live throughout the water columns! So, what happens if #GDGT from deep Archaea mixed in the #sedimentary GDGTs... Taylor et al. 2013 have shown that increased inputs from deep archaeal clades can be detected by the ratio of GDGTs with 2 and 3 rings (GDGT-2/-3). (4/10) 120
Ronnie Rattanasriampaipong @paleolipidrr.bsky.social · 21/06/2025Let's start with #GDGTs & #TEX86. #Archaea adjust the internal structures of their membrane lipids (aka #GDGT) to thrive in a wide range of temp. Marine archaea make #GDGT w/ 0-4 cyclopentyl rings. Hotter?! Let's add more rings! This is the basis of #TEX86 #SST proxy. (3/10) 110
