Photosynthetic primary production in the Mesoproterozoic

New Phytologist, Volume 251, Issue 1, Page 64-80, July 2026.
Summary The Mesoproterozoic atmosphere had more CO2 and less O2 than at present. While the upper ocean was oxygenated, the deeper ocean was euxinic or ferruginous. Primary production was performed by Chlorobia, Cyanobacteria, Proteobacteria, and Archaeplastida.

Amphoras on Knidian amphoras

, 2011
The article traces the motif of an amphora in the iconography of Knidian amphora stamps in an effort to date with greater precision a Knidian amphora with two stamped handles discovered in the excavations at Marina el-Alamein. In effect, the handleless amphora stamp on the container from Marina was assigned to Period VII and dates most probably to the ...

Reversible Regime Change: Climate‐Driven Phytoplankton Community Shifts in the Cariaco Basin, Venezuela

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract Phytoplankton communities are integral to oceanic biogeochemical cycles and are sensitive indicators of climate‐driven environmental variability. Long‐term time series capture this variability, allowing us to unravel the effects of environmental change on local communities.

Greek Commodities in Phoenicia: An Interdisciplinary Study of Imported Amphorae From Tell el‐Burak (Lebanon)

Archaeometry, Volume 68, Issue 3, Page 395-408, June 2026.
ABSTRACT This paper examines transport amphorae of Greek/Aegean types from the 7th–4th c. BCE imported to the Phoenician coastal settlement of Tell el‐Burak, Lebanon. We present a selection of 58 pieces analyzed by typological, chemical (NAA), and petrographic approaches.

Methods for Improving Settlement and Metamorphosis of Shelled Marine Mollusks in Aquaculture: A Review

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
Settlement and metamorphosis are key developmental hurdles in marine mollusk aquaculture. Environmental signals (such as biofilms, algae, and signals from conspecifics) and biochemical pathways (including nitric oxide, thyroid hormones, catecholamines, and GABA) regulate the transition of larvae into benthic juveniles. Combining ecological observations

Diatoms–copepods: An evolutionary arms race

Limnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract Diatoms and copepods are dominating and diverse groups of phytoplankton and zooplankton, respectively. Diatoms account for 25–40% of ocean primary production, and their main predators, copepods, are arguably the most abundant group of metazoans in the ocean, typically accounting for ~ 80% of zooplankton biomass.

The Oldest Traces of Alcoholic Beverages in the Border Zone of the North and East European Plains

Archaeometry, Volume 68, Issue 2, Page 153-172, April 2026.
ABSTRACT Analysis of organic compounds preserved on pottery from the Bell Beaker community and the initial phase of the Trzciniec Cultural Sphere in the border zone of the Eastern and North European Plains was prompted by traces of alcoholic beverages found in contextually and formally analogous discoveries of more westerly provenance.

Influence of Ploidy and Genetic Background on Stress Tolerance of Intraspecific Yeast Hybrids

Microbial Biotechnology, Volume 19, Issue 3, March 2026.
A large set of intraspecific yeast hybrids was constructed using two strategies that yielded series of hybrids with variable ploidy. Phenotyping of the hybrids was carried out in high‐stress media to assess the effects of ploidy and genetic background on heterosis.
