Global Patterns and Drivers of Climatic Niche Originality and Overlap: Disentangling Ecological From Methodological Signals

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
This study presents BioOverlap, a global database quantifying macroclimatic niche properties, niche overlap, and geographic range overlap for ~16,000 species. Analyses reveal that niche originality consistently reflects ecological factors such as niche breadth, productivity, and climatic heterogeneity, whereas pairwise niche–range relationships are ...

Food limitation and growth in temperate epipelagic appendicularians (Tunicata) [PDF]

open access: yesMarine Ecology Progress Series, 2003
Through an extensive review of reports on appendicularian ecology, we have developed a set of equations on the feeding, metabolic and growth rates of temperate epipelagic appendicularian species. We have used these equations to study the conditions in which these species are likely to ex- perience food-limited growth.

Results of the trawl survey of nekton and macroplankton during preanadromous migrations of pacific salmon in the North-West Pacific in 2023

open access: yesИзвестия ТИНРО
Results of the trawl survey in the Pacific waters at Kuril Islands within and outside EEZ of Russia conducted by RV TINRO in June-July 2023 are analyzed. Data on spatial distribution, abundance and biomass of fish, cephalopod and jellyfish species in the

Dive behaviour and foraging effort of female Cape fur seals Arctocephalus pusillus pusillus [PDF]

open access: yesRoyal Society Open Science, 2019
While marine top predators can play a critical role in ecosystem structure and dynamics through their effects on prey populations, how the predators function in this role is often not well understood.

First Report on the Diet of the Angolan Flying Squid (Todarodes angolensis) in New Zealand Waters

open access: yesNew Zealand Journal of Zoology, Volume 53, Issue 3, September 2026.
The Angolan flying squid (Todarodes angolensis) is a southerly distributed, large‐bodied ommastrephid preyed upon by many large marine vertebrates such as the southern elephant seal and deep‐sea squalid sharks. Here, we report its diet in New Zealand waters for the first time, identifying prey items from the stomach contents of 58 adults using ...

Models of iron speciation and concentration in the stratified epipelagic ocean [PDF]

open access: yesGeophysical Research Letters, 2011
Surface ocean iron speciation is simulated using a time‐dependent box‐model of light‐mediated redox cycling over a range of aeolian inputs of soluble iron in the stratified epipelagic ocean. At steady‐state, Dissolved iron (DFe) concentration increases with aeolian input of soluble iron up to 0.1 μmol m−2 d−1, and is limited by the solubility of ferric

Influences of physical dispersal and environmental selection on mesopelagic and epipelagic zooplankton distributions at multiple scales across the North Pacific Ocean [PDF]

open access: yes, 2023
The processes influencing biogeographic distributions and community composition in the mesopelagic ocean are not well understood. In the pelagic ocean, the magnitude of dispersal potential and environmental variability vary with depth.

Zooplankton vertical stratification in the East-pacific and Indian sectors of the Southern Ocean

open access: yesFrontiers in Marine Science
IntroductionIn the Southern Ocean, the large-scale distribution of zooplankton, including their abundance and community composition from the epipelagic to the upper bathypelagic layers, remains poorly understood.

The diverse bivalved arthropods of Castle Bank (Darriwilian, Ordovician), Wales

open access: yesPapers in Palaeontology, Volume 12, Issue 5, September/October 2026.
Abstract The Darriwilian (Didymograptus murchisoni Biozone, Middle Ordovician) Castle Bank Lagerstätte, near Llandrindod, Wales (UK) hosts a diverse assemblage of marine animals, generally under 10 mm in size. Here we provide an overview of the diversity of bivalved arthropods from Castle Bank.

From the light blue sky to the dark deep sea: Trophic and resource partitioning between epipelagic and mesopelagic layers in a tropical oceanic ecosystem

open access: yes, 2023
International audienceThe connection between epipelagic and deep-sea mesopelagic realms controls a variety of ecosystem processes includ-ing oceanic carbon storage and the provision of harvestable fish stocks. So far, these two layers have been mostly ad-
