Lagged responses in the composition of small mammal communities to a century of climate change

Ecography, Volume 2026, Issue 4, April 2026.
Climate change has widespread effects on the distribution, abundance and behavior of species around the world, leading to the reshuffling of ecological communities. However, it remains unclear whether individual species' range shifts scale up to result in communities whose rate of change lag, lead, or track the rate of climate change. We capitalized on

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

Submarine canyons in the Catalan Sea (NW Mediterranean): Megafaunal biodiversity patterns and anthropogenic threats [PDF]

, 2012
12 pages, 13 figuresThe continental margin of the Catalonia is crossed by several submarine canyons of different evolutionary history (Fig. 1) (Canals et al., 2004a).

Geochemical Disequilibrium at the Brittle‐Ductile Transition

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract We investigate the microtextural, microchemical, and isotopic effects of late‐stage ductile deformation in quartzite mylonites and kyanite–muscovite–quartz veins from the Raft River shear zone (Utah). Quartz microstructures record pervasive disequilibrium, expressed by unannealed features including undulatory extinction, deformation lamellae ...

Quantitative fish survey of the submarine canyons of the iSimangaliso Wetland Park [PDF]

, 2015
There have been no quantitative studies of fish species associated with the submarine canyons of the north east coast of South Africa. These canyons offer protection to coelacanths Latimeria chalumnae, fish of commercial importance, and a number of ...

Modeling Upper Ocean Ecosystem Dynamics in Response to Interannual Sea‐Ice Variability in the Western Antarctic Peninsula

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 4, April 2026.
Abstract In the Western Antarctic Peninsula (WAP), marine plankton dynamics are tightly linked to the interannual variability in environmental conditions, including phenological shifts in sea‐ice seasonality. To explore these linkages, we use a 1‐dimensional vertical ocean‐ice‐ecosystem model (KPP‐Eco‐Ice, or KEI) that simulates physical and ecosystem ...

Seismic Stratigraphy of the Peruvian Forearc Drifts from 3° to 7°S: Identification and Influence of Lower Layers of the Humboldt Current System

Paleoceanography and Paleoclimatology, Volume 41, Issue 4, April 2026.
Abstract The seafloor morphology and subsurface geometry of a late Neogene contourite drift located along the Peru margin is documented for the first time using multibeam bathymetry, two‐dimensional and three‐dimensional seismic data. Along the margin several submarine canyons incise the shelf and slope.

Trawling-Induced Sedimentary Dynamics in Submarine Canyons of the Gulf of Palermo (SW Mediterranean Sea)

Journal of Marine Science and Engineering
Bottom trawling in submarine canyons can affect their sedimentary dynamics, but studies addressing this topic are still scarce. In the Gulf of Palermo (NW Sicily, SW Mediterranean Sea), bottom trawling occurs on the continental slope, but principally ...

Slope Instability along the northeastern Iberian and Balearic continental margins [PDF]

, 2007
This paper gathers the available information on submarine landslides identified in the northeastern Iberian continental margin and presents new data on both already known landslides and new, previously unknown ones.

Accounting for Intra‐ and Intergenomic Sequence Variation in Reference Barcodes Improves eDNA Metabarcoding Biodiversity Assessment

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Environmental DNA (eDNA) metabarcoding can rapidly characterise biodiversity, yet its accuracy and effectiveness are limited by incomplete DNA barcode reference databases. We evaluated how comprehensive reference databases that include sequence variation within genomes (intragenomic) and across individuals and species (intergenomic) improve ...
