Archaeal Tetraether Lipids as Tracers for Past Marine Environmental Change

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.
Abstract Archaea are single‐celled microorganisms that are abundant in marine environments and play a key role in the carbon and nitrogen cycles. Archaea can biosynthesize a wide variety of isoprenoid membrane lipids, including isoprenoid glycerol dibiphytanyl glycerol tetraethers (isoGDGTs).

Triple Oxygen and Hydrogen Isotopes of Soil Water Across Climates, Seasons, and Depths

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Soil waters are a central component of the terrestrial water cycle. Their δ2H, δ18O, and d‐excess values contain rich information about hydroclimate, including the source of moisture and its evaporative history. Paleoclimate workers seek to investigate ancient hydroclimates via triple oxygen isotope geochemistry, termed Δ′17O, which is ...

MorphSim: An R package for simulating discrete morphological data

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 7, Page 2018-2027, July 2026.
Abstract Morphological data are essential for reconstructing evolutionary histories, particularly for fossil taxa, as they represent the primary source of information for integrating extinct lineages into phylogenetic analyses. Despite this, tools for simulating realistic morphological datasets for fossil‐inclusive phylogenetic workflows remain limited.

Taxonomic and functional diversity of benthic foraminifera as a promising proxy for tidewater glacier retreat

open access: yesBoreas, Volume 55, Issue 3, Page 885-902, July 2026.
Ice sheets and glaciers globally are losing mass at increasing rates, with the strongest changes occurring at tidewater glaciers. These are rapidly retreating and often transitioning to land‐terminating with implications for sea level change and ecosystem functioning.

Leaf Size in Conifers: Global Associations With Climate and Evolutionary History

open access: yesGlobal Change Biology, Volume 32, Issue 7, July 2026.
Global patterns in leaf size are linked to climatic trade‐offs, so we explore these relationships in a major group of plants, the conifers. Using contemporary phylogenetic methods, we show that conifers display a strong pattern of evolutionary conservatism in the association of leaf size with climate, and highlight that these relationships are driven ...

LIFE DETECTION SYSTEM FOR MONITORING PARAMETERS IN FOSSILIZATION PROCESS

open access: yes, 2016
Introduction: The Life Detection System (LDS) is designed as a two modules system for microbial life detection under growing conditions. The microbes growth is followed by redox, pH and conductivity parameters but others parameters can be monitored as ...

Novel Glomeromycotina–moss associations identified in California dryland biocrusts

open access: yesNew Phytologist, Volume 251, Issue 1, Page 151-163, July 2026.
Summary Drylands, which comprise c. 45% of Earth's land area, host biological soil crusts (biocrusts): symbiotic communities of cyanobacteria, fungi, algae, lichen, and bryophytes that stabilize soil and support key ecosystem functions. Moss‐dominated biocrusts are particularly interesting due to their potential to illuminate ancient bryophyte–fungal ...
