Temperature‐Driven Silicate Weathering Feedbacks Terminated the Middle Eocene Climatic Optimum

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Continental hydroclimate dynamics and its responses during the Middle Eocene Climatic Optimum (MECO, ∼40 Ma) remain largely unexplored. Here, we present high‐resolution multi‐proxy records from four East Asian lake basins that demonstrate precipitation, chemical weathering, and terrestrial input underwent multi‐phase changes during the MECO ...

Bioenergetic trophic trade‐offs determine mass‐dependent extinction thresholds across the Cenozoic

Ecology, Volume 107, Issue 5, May 2026.
Abstract Body size constrains trophic interactions, shaping the feasibility of species' populations. Over macroevolutionary timescales, these constraints feed back to shape selection on body size and diet. We develop a bioenergetic, three‐level trophic framework—typical of terrestrial mammalian ecosystems—to explore how bioenergetic trade‐offs emerging

Comparative Assessment of Freshwater Biodiversity in Los Morales Reservoir (Madrid) Using eDNA Collected From Sponges and Water Filtration

Environmental DNA, Volume 8, Issue 3, May–June 2026.
Filters and freshwater sponge tissue recover a comparable number of taxa through eDNA metabarcoding. Filters detect more taxa, followed by sponge tissue when host‐blocking primers are used. Each method reveals different community compositions, so combining both approaches is recommended to achieve a more realistic representation of the metazoan ...

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.

Post‐Eocene 90° CCW Rotation of Sardinia‐South Corsica: Paleomagnetic Evidence From Permian‐Cretaceous Sediments of Nurra (NW Sardinia)

Tectonics, Volume 45, Issue 5, May 2026.
Abstract The paleomagnetism of Miocene calc‐alkaline volcanics and sediments from Sardinia has firmly showed that the Corsica‐Sardinia microplate rotated 50°–60° counterclockwise (CCW) with respect to Europe between 21 and 15 Ma, during its drift from the Provencal margin. However, Permian to Eocene rocks from central‐south Sardinia revealed higher (up
