Long distance biotic dispersal of tropical seagrass seeds by marine mega-herbivores

open access: yesScientific Reports, 2017
Terrestrial plants use an array of animals as vectors for dispersal, however little is known of biotic dispersal of marine angiosperms such as seagrasses.

Evolution of the α‐Glucosidase Gene Family in Apoidea

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
This study traces the origin of the α‐glucosidase gene family in bees back to approximately 140 million years ago, revealing that its evolutionary history closely aligns with the rise of angiosperms and coevolution. Furthermore, by identifying the core members Hbg1–3 and 28 key functional sites driven by positive selection, the study systematically ...

Seagrass species diversity in Tanzania based on morphological and molecular data

open access: yesNordic Journal of Botany, Volume 2026, Issue 9, September 2026.
Seagrass diversity along the Tanzanian coast has been documented mainly through morphology, with limited molecular reference data available for Tanzania and the wider Western Indian Ocean. This study combined morphological identification with nuclear ribosomal internal transcribed spacer (ITS) and plastid ribulose‐1,5‐bisphosphate carboxylase/oxygenase

New metabolites with antibacterial activity from the marine angiosperm Cymodocea nodosa

open access: yesTetrahedron, 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 ...

Stable isotopic evidence for increased terrestrial productivity through geological time

open access: yesScientific Reports
Marine life on Earth is known back to the Archean Eon, when life on land is assumed to have been less pervasive than now. Precambrian life on land can now be tested with stable isotopes because living soil CO2 is isotopically distinct for both carbon and

Metagenomic Evidence of Microbial Community Responsiveness to Phosphorus and Salinity Gradients in Seagrass Sediments

open access: yesFrontiers in Microbiology, 2018
Sediment microorganisms can have profound influence on productivity and functioning of marine ecosystems through their critical roles in regulating biogeochemical processes.

Initial colonization by bryophytes and ferns during primary succession on Nishinoshima, Japan

open access: yesNordic Journal of Botany, Volume 2026, Issue 9, September 2026.
Volcanic islands that have experienced complete vegetation loss following recent eruptions provide rare opportunities to observe the earliest stages of ecosystem recovery. Nishinoshima, an oceanic island located approximately 1000 km south of mainland Japan, underwent major volcanic activity between 2013 and 2020, eradicating all pre‐existing ...

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

open access: yesThe 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 ...

Non‐Fungi Diversity Present in Soil and Snow Impacted by Anthropogenic Activity in King George Island, Maritime Antarctica Using Metabarcoding Approach

open access: yesJournal of Eukaryotic Microbiology, Volume 73, Issue 5, September/October 2026.
ABSTRACT The Antarctic Peninsula shows a fast‐rising temperature trend, increasing the risk of colonization by non‐native species, such as the invasive Poa annua. The “cryptic diversity” of largely unknown microscopic propagules in soil and snow poses a significant threat, as traditional morphological surveys are inadequate.
