Bottom-up controls, ecological revolutions and diversification in the oceans through time.

TL;DR: In this paper , the authors used principal component analysis (PCA) to identify the major sources of influence on the coastal waters adjacent to a major tourist facility (an aquarium) in southern Taiwan, followed by the construction of a structural equation model (SEM) to determine the direct and indirect effects of the abiotic factors on phytoplankton and zooplp density and diversity.

TL;DR: Use of satellite imagery to estimate distribution and abundance of Cumberland Sound beluga whales reveals frequent use of a glacial river estuary. The estimated abundance was highest in 2020 and lowest in 2021 and 2022. The only critical habitat identified was in Clearwater Fiord, in or near the estuary freshwater plume and in a bay to the west of the plume.

TL;DR: Initial coring at Prees, Cheshire Basin, UK, has yielded a complete succession of Early Jurassic mudstone and Quaternary cover sediments. The recovered core spans a wide range of ages from Late Triassic to Early Jurassic and includes all ammonoid chronozones. The lithological succession comprises the Branscombe Mudstone and Blue Anchor formations of the Mercia Mudstone Group, the Westbury and Lilstock formations of the Penarth Group, and the Redcar Mudstone Formation of the Lias Group. Organic carbon enrichment occurs in the Rhaetian (Late Triassic) Westbury Formation and in the earliest Hettangian and earliest Pliensbachian strata of the Redcar Mudstone Formation.

TL;DR: Researchers discover the oldest mysticete in the Northern Hemisphere, Fucaia humilis, dating back to the latest Eocene (34.5 Ma ago), suggesting a possible link between kelp ecosystem development and the radiation of small-sized toothed mysticetes in the North Pacific.

TL;DR: In this paper, the authors present a new compilation of trilobite alpha diversity based on field collections and survey of the literature, showing that trilabite species richness within nearshore, shallow subtidal, carbonate buildup and deep subtidal shelf environments was essentially constant between the Late Cambrian and the Late Ordovician.

TL;DR: It is shown that drill-hole size is a robust predictor of body size among modern drilling predators and that drill -hole size rose substantially from the Ordovician to the Quaternary period, whereas the size of drilled prey remained stable, which indicates a directional increase in predator-prey size ratios.

TL;DR: Estimates of mean per capita metabolic rates of tropical to subtropical assemblages of shallow-marine gastropods both before and after the Mesozoic Marine Revolution support the hypothesis that benthic energy budgets increased during the MMR, possibly in response to rising primary productivity.

TL;DR: In this article, the authors investigated the role of mixotrophic dinoflagellates and diatoms in the evolution of modern phytoplankton evolution.
