Early evolutionary history of the seed
Biological Reviews, Volume 101, Issue 3, Page 1511-1553, June 2026.ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Hornblendite in the Lower Crust: A Possible Source for Porphyry Cu Deposits
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.Abstract Lower crustal sulfide‐bearing Cu‐rich cumulates, mainly occurring as hornblendite, have been proposed as a critical source component for the development of giant porphyry Cu deposits (PCDs); however, their mineralogical and geochemical nature remain elusive.

Revealing Permafrost Continuity Across a Northern Watershed With Airborne Electromagnetics
Journal of Geophysical Research: Earth Surface, Volume 131, Issue 5, May 2026.Abstract Permafrost thawing in northern regions may alter groundwater‐surface water dynamics, thereby impacting hydrologic and ecologic functions and the potential release of stored solutes including carbon. Here, we present an airborne frequency‐domain electromagnetic survey over a discontinuous permafrost region within the Central Mackenzie Valley in

Late Devonian red tide and mass extinction
Chinese Science Bulletin, 2002 Molecular stratigraphical, carbonate carbon isotopic, stratigraphical and paleontological data show that algal booming, eutrophication, anoxia, hypersalinity, positive δ13C excursion and biomass decreasing occurred in the offshore carbonate environments of the Frasnian-Famennian (F-F) transition, which hints that red tide might frequently take place in
