Geostandards and Geoanalytical Research, EarlyView.Key Points Higher laser repetition rate, fluence and larger spot size increase signal intensity. Higher laser repetition rate produces overlaps in aerosolised particles, improving signal stability and precision. For Sr‐rich materials, moderate spot diameter (≤ 60 μm), 3 J cm‐2 fluence and ≥ 12 Hz repetition rate are recommended.

Journal of Phycology, EarlyView.Abstract Three novel taxa in the Coleofasciculales were observed in hot springs in Yellowstone National Park, Wyoming, United States, and in the Tabaconcito thermal springs on the Rio Tabacón in Costa Rica. Flavicapitulum vaporiphilum gen. et sp. nov. was located in a supported clade with Gracilinea and Marmoreocelis.

Depositional record of historic lahars in the Whangaehu Gorge, Mt. Ruapehu [PDF]
, 2008 Mt. Ruapehu is one of the most lahar prone volcanoes in the world, having both a crater lake and six small glaciers upon its 2797 m summit. The major outlet for the crater lake, the Whangaehu Gorge, has hosted over 46 historic lahars.

Journal of Phycology, EarlyView.Abstract Picocystis salinarum is an early‐diverging chlorophyte and the sole described member of the Picocystophyceae, frequently dominating hypersaline and alkaline lakes despite extreme physicochemical constraints. To elucidate the genomic foundations of its ecological success, we generated a fully annotated, chromosome‐scale nuclear genome assembly ...

Meteoritics &Planetary Science, EarlyView.Abstract Shergottites are the most abundant meteorites from Mars and a major source of information on magma reservoirs, transport, and eruption, particularly in the late Hesperian northern hemisphere. Conflicting interpretations have arisen on the crystallization conditions of pyroxene in olivine‐phyric shergottites.

Restoration Ecology, EarlyView.Abstract Introduction Since European settlement, Australia's Wet Tropics bioregion has been extensively cleared, leaving a mosaic of rainforest fragments, crops, pastures, orchards, and human settlement. Fragment isolation leads to declines in faunal diversity and genetic variability, effects potentially exacerbated by climate change. Restoring habitat
