Submarine landslides and canyons: slope degradation and shelf-edge indentation in a tectonically active margin (Finale Basin, Northern Sicilian Margin, Tyrrhenian Sea)

Frontiers in Earth Science
Submarine canyons and landslides are closely related geological features of continental margins. They prevail on the continental slope and often reach the shelf edge, indenting the continental shelf. The character of the linkage between submarine canyons

Aciphylla latipinna, a New Species of Large Taramea, Speargrass (Aciphylleae, Apiaceae) From the Southern South Island of New Zealand

New Zealand Journal of Botany, Volume 64, Issue 3, September 2026.
Aciphylla latipinna Perrie, Glenny, & L.D.Sheph. is newly described after testing the morphological and genetic distinctness of a long‐recognised unresolved taxonomic entity whose informal names include Aciphylla aff. horrida (a) (CHR 511521; Lomond). Analyses of genetic data from ddRADseq DNA sequencing found A.

Enhancing Intra‐Specific Population Genetic Studies of Bottlenose Dolphins (Tursiops truncatus) in Irish Waters by Integrating Least Invasive Sampling and Environmental DNA (eDNA)

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Three populations of bottlenose dolphins are found in Irish waters. This study used direct sampling methods to expand the sample size and confirm the distinctiveness of these populations, including a range expansion outside of the Shannon Estuary SAC.

Reconciling morphological and molecular approaches: The integrative taxonomy of Leucobryum (Leucobryaceae) in the Malagasy region

TAXON, Volume 75, Issue 4, August 2026.
Abstract Leucobryum (Leucobryaceae) is a genus of moss (Bryophyta) that has been poorly investigated in Africa, particularly in the western Indian Ocean region. This study integrates morphological and molecular data to revise the taxonomy of the genus in this area.

Evidence for littoral convergence and sediment delivery to Mattole submarine canyon, Northern California

Frontiers in Earth Science
At geologic timescales, a significant proportion of the sediment eroded from continents is transferred from rivers to littoral cells, then through submarine canyons to deep ocean basins.

Ecology of reintroduced Rocky Mountain bighorn sheep in Dinosaur National Monument La Ecología de Borrego Cimarron de las Montañas Rocosas Reintroducido en el Monumento Nacional de Dinosaurio

Wildlife Monographs, Volume 223, Issue 1, August 2026.
We synthesized GPS telemetry, genetic, and pathogen data to evaluate metapopulation processes in a reintroduced Rocky Mountain bighorn sheep (Ovis canadensis canadensis) population in Dinosaur National Monument. We estimated subpopulation‐specific abundances and found 4 small subpopulations with high genetic diversity, partial connectivity, and ...

Power Estimates Associated With Internal Tides From the Monterey Bay Area [PDF]

Oceanography, 2012
Numerical modeling has proven to be a useful method for simulating internal tides within the coastal ocean. Monterey Bay is a location that experiences energetic semidiurnal internal tides, and they are pronounced within Monterey Submarine Canyon ...

Seasonal and Interannual Variability of Antarctic Bottom Water Downstream of the Four Key Formation Regions

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Antarctic Bottom Water (AABW) is a cold, dense water mass formed around Antarctica that ventilates the global abyssal ocean. Recent studies have reported widespread warming, freshening, and thinning of AABW, yet its temporal variability remains poorly constrained because of sparse observations.

Eocene to Miocene U‐Pb Geochronology Evolution of the Rio Grande Rise, Southwestern Atlantic: A Paleoceanographic Approach

Paleoceanography and Paleoclimatology, Volume 41, Issue 8, August 2026.
Abstract The Rio Grande Rise (RGR) is a major submarine feature in the South Atlantic that plays an important role in regional oceanographic dynamics. This study presents new U‐Pb geochronology of sedimentary rocks from the RGR, offering direct age constraints on carbonate and apatite embedded within Fe‐Mn crusts and associated foraminifera fossils ...

Tectonic activity and river mouth proximity drive submarine canyon retreat along Italian coasts

Communications Earth & Environment
Active tectonics and coastal deformation predispose continental margins to submarine gravitational instability and canyon head retreat. Here we investigate the drivers of this susceptibility along the Italian coasts.
