Intensification of Northern Hemisphere Glaciation Triggered the Red Clay to Loess‐Paleosol Shift on the Chinese Loess Plateau 2.7 Million Years Ago

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Widespread aeolian loess‐paleosol and red clay sediments on the Chinese Loess Plateau (CLP) provide a globally unique terrestrial archive of Neogene–Quaternary climate. However, the timing and associated mechanisms of red clay to loess‐paleosol shift remain debated.

The unique structural and biochemical development of single cell C4 photosynthesis along longitudinal leaf gradients in Bienertia sinuspersici and Suaeda aralocaspica (Chenopodiaceae)

Journal of Experimental Botany, 2016
Highlight In family Chenopodiaceae, two unique forms of single cell C4 photosynthesis with different evolutionary origins show convergence in structural and biochemical expression of C4 traits during leaf ontogeny.

Early to Mid‐Holocene Cool Temperature‐Induced Drought in Asian Interior

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Hydroclimatic variations in mid‐latitude Asia during the early to mid‐Holocene and associated mechanisms remain disputed, hampering our understanding of atmospheric circulation controls on regional climatic changes. We report Holocene alkenone records from two Siberian lakes, documenting lake temperature and hydrological changes, and ...

Molecular phylogeny and forms of photosynthesis in tribe Salsoleae (Chenopodiaceae)

Journal of Experimental Botany, 2016
While many C4 lineages have Kranz anatomy around individual veins, Salsoleae have evolved the Salsoloid Kranz anatomy where a continuous dual layer of chlorenchyma cells encloses the vascular and water‐storage tissue.

Notes on the germination of the endangered species Sclerolaena napiformis (Chenopodiaceae) [PDF]

, 2013
Sclerolaena napiformis is found on fertile plains in northern Victoria and southern New South Wales and is endangered Australia-wide. Introductory work on its germination shows that seeds cannot germinate until the woody fruit has broken down.

Relative pollen productivity estimates from India: A step towards quantitative reconstruction of past plant abundance

Ecosphere, Volume 17, Issue 2, February 2026.
Abstract Pollen records and models of pollen–vegetation relationships are required to reconstruct past plant abundances during the Holocene to answer specific questions on climate history, human impact, biodiversity, and their interactions. An important parameter for model applications is pollen productivity, estimated as relative pollen productivity ...
