Contrasting Dispersal Histories Shape Distinct Evolutionary Trajectories Between Malesian and Pantropical Talipariti (Malvaceae)

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Talipariti (Malvaceae) comprises two lineages with contrasting geographic ranges across Malesia: a pantropical sea hibiscus group and a Papuan group restricted to New Guinea and adjacent islands. Using phylogenomics, divergence‐time estimation, and quantitative biogeographical modelling applied to herbarium‐derived genomic data, we demonstrate that the

Cretaceous-Tertiary Foraminifera and Palynomorphs from Djega Section and Inferred Paleodepositional Environments, Rio Del Rey Basin, Cameroon, West Africa

The Scientific World Journal, 2018
Late Cretaceous-Paleocene foraminiferans and palynomorphs were recovered from the upper section of the Djega outcrop in the Rio del Rey Basin. Only a few planktonic foraminiferan species of the genera Heterohelix and Hedbergella were recovered among an ...

Palaeontology of the upper Turonian paralic deposits of the Sainte-Mondane Formation, Aquitaine Basin, France

Geologica Acta, 2016
The upper Turonian lignite deposits of Sainte-Mondane, Dordogne (Aquitaine Basin, SW France), consist of clays bearing translucent, orange to red, amber micrograins. The amber exhibits different types of microbial inclusions.

Making fish oils in plants: from alpha to omega

New Phytologist, Volume 251, Issue 3, Page 1013-1018, August 2026.
Schematic representation of the biosynthetic pathway for the synthesis of omega‐3 long‐chain polyunsaturated fatty acids. The sequential transgene‐encoded activities required to convert endogenous fatty acids to the longer chain polyunsaturated forms of eicosapentaenoic acid and docosahexaenoic acid are shown in red.

New metabolites with antibacterial activity from the marine angiosperm Cymodocea nodosa

Tetrahedron, 2008
Four new metabolites (1–4) have been isolated from the organic extract of the seagrass Cymodocea nodosa, collected at the coastal area of Porto Germeno, in Attica Greece. Compounds 1 and 2 belong to the structural class of diarylheptanoids, which have been found only once before in marine organisms [Kontiza, I.; Vagias, C.; Jakupovic, J.; Moreau, D ...

Spatial inference of ancestor locations suggests northern refugia for canopy‐forming kelps in the Pacific Northwest

New Phytologist, Volume 251, Issue 4, Page 2248-2265, August 2026.
Population genetic structure in the Pacific Northwest for (a–c) Nereocystis and (d–f) Macrocystis. Summary Pockets of the formerly glaciated Pacific coastline of North America likely remained ice‐free throughout the Last Glacial Maximum (LGM). These areas may have served as refugia for terrestrial species, but less is known about their role in the ...

Modelling of fatty acids signatures predicts macroalgal carbon in marine sediments

Ecological Indicators
Differentiating between carbon contributors in marine environments is crucial to gaining a deeper understanding of marine carbon sequestration, and some efforts have been made through the application of various approaches.

EVALUATING THE ROLE OF SEAGRASS IN CENOZOIC CO2 VARIATIONS

Frontiers in Environmental Science, 2016
Marine seagrass angiosperms play an important role in carbon sequestration, removing carbon dioxide from the atmosphere and binding it as organic matter.
