Geophysical Monograph Series, Page 1-26., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Prokaryotic PfaB is a terminal acyltransferase that determines the final PUFA product. [PDF]
Protein SciAbstract Omega‐3 polyunsaturated fatty acids (PUFAs) are essential for human health due to their numerous beneficial biological properties. These compounds are synthesized in marine bacteria and eukaryotic microalgae by PUFA megasynthases (Pfas), which are evolutionarily related to fatty acid synthases (FAS) and polyketide synthases (PKS). In FAS, PKS,

Brooding Phylogenomics: Target-Capture Probe Sets for the Analysis of Ultraconserved Elements in the Peracarida. [PDF]
Mol Ecol ResourABSTRACT Sequencing via target capture has been used to great effect in phylogenetic studies of organisms such as insects, arachnids and vertebrates. However, other taxa have received limited genomic attention despite their diversity and the intensity of research on such groups. Here, we describe generalised probe sets targeting ultraconserved elements

Age of the Ordovician sedimentary succession in Lumparn Bay, Åland Islands, Finland [PDF]
Estonian Journal of Earth Sciences, 2023 Depression of the ancient Lumparn meteorite impact structure in the à land Islands is partly infilled with the lower Palaeozoic sediments, lying presently below sea level. The Cambrian and Ordovician sedimentary cover is distributed in the area of 15 km2,

Middle–Late Ordovician organic- walled phytoplankton from Sweden: diversity and early radiation [PDF]
Estonian Journal of Earth Sciences, 2023 The Borenshult-1 core, drilled in the vicinity of Motala, east of Lake Vättern in south central Sweden, comprises a well-dated and nearly complete succession of marine marly carbonates deposited relatively close to land. The 34 core samples analyzed for

Provenance shift in Cambrian mid-Baltica: detrital zircon chronology of Ediacaran–Cambrian sandstones in Estonia [PDF]
Estonian Journal of Earth Sciences, 2014 In order to clarify the tectono-sedimentary history of Paleozoic Baltica, age spectra of detrital zircon grains from the Ediacaran (Kotlin Regional Stage) and Lower Cambrian sandstones (lowermost Lontova and Lükati formations) in western Estonia in ...
