New database of bottom trawl stations performed in the Far-Eastern Seas and the North Pacific in 1977-2010

open access: yesИзвестия ТИНРО, 2014
New database (DB) is presented of 224 fishery-independent bottom trawl surveys (32699 trawl stations) conducted in the last 34 years in the North Pacific and adjacent regions - the Bering, Okhotsk, and Japan/East.

Stable Isotope Analysis of Food Web Structure and the Contribution of Carbon Sources in the Sea Adjacent to the Miaodao Archipelago (China)

open access: yesFishes, 2022
The littoral zones around archipelagos are highly productive coastal habitats that serve as biodiversity hotspots and provide valuable ecosystem services that are different from those of the pelagic and profundal zones.

Contribution des zones d'échanges entre eau de surface et eau souterraine à la biodiversité des hydrosystèmes : exemple d'une rivière méditerranéenne, la Cèze

open access: yesPhysio-Géo, 2019
In a close future, Mediterranean rivers will support strong disturbances due to climate changes, with inexorable consequences for their fauna. The invertebrate biodiversity of the Cèze River (South of France) was studied in a karstic area.

ORNATODELLA ANAN, A NEW YPRESIAN ROTALIID BENTHIC FORAMINIFERAL GENUS FROM PAKISTAN [PDF]

open access: yesGeological Behavior, 2023
Ornatodella Anan is introduced here to elucidate a new Ypresian Rotaliid benthic foraminiferal genus, which represents a transition from between the two benthic foraminiferal genera: Ornatanomalina Haque, 1956 (with the spiraling ribs in the end stage of

Habitat heterogeneity and its influence on benthic biodiversity in oxygen minimum zones [PDF]

open access: yesMarine Ecology, 2010
AbstractOxygen minimum zones (OMZs; midwater regions with O2 concentrations <0.5 ml l−1) are mid‐water features that intercept continental margins at bathyal depths (100–1000 m). They are particularly well developed in the Eastern Pacific Ocean, the Arabian Sea and the Bay of Bengal.

Facies and paleoenvironmental reconstruction of Early–Middle Miocene deposits in the north-west of the Zagros Basin, Iran

open access: yesGeologica Carpathica, 2019
Facies analysis and paleoenvironmental reconstruction of the Burdigalian to Langhian Asmari Formation, outcropping in the Khorram Abad Anticline, in the north-west of the Zagros Basin allow us to interpret the carbonate ramp history during the Early ...

Microbial interactions in marine water amended by eroded benthic biofilm: A case study from an intertidal mudflat [PDF]

open access: yesJournal of Sea Research, Elsevier, 2014, 92, pp.74 - 85, 2014
In shallow macrotidal ecosystems with large intertidal mudflats, the sediment-water coupling plays a crucial role in structuring the pelagic microbial food web functioning, since inorganic and organic matter and microbial components (viruses and microbes) of the microphytobenthic biofilm can be suspended toward the water column.

New high-tech flexible networks for the monitoring of deep-sea ecosystems [PDF]

open access: yesEnvironmental Science and Technology 53 12 (2019) 6616-6631, 2022
Increasing interest in the acquisition of biotic and abiotic resources from within the deep sea (e.g. fisheries, oil-gas extraction, and mining) urgently imposes the development of novel monitoring technologies, beyond the traditional vessel-assisted, time-consuming, high-cost sampling surveys.

Variation in fatty acid content among benthic invertebrates in a seasonally driven system

open access: yesLimnology and Oceanography Letters, 2023
At temperate latitudes where seasonal changing environmental conditions strongly affect the magnitude, duration and species composition of pelagic primary production, macrobenthic organisms living below the photic zone rely on the sedimentation of ...

Revealing the influence of hyporheic water exchange on the composition and abundance of bottom-dwelling macroinvertebrates in a temperate lowland river

open access: yesKnowledge and Management of Aquatic Ecosystems, 2021
We studied distributions and abundances of macroinvertebrates in relation to hyporheic water exchange (HWE) patterns of the upper Biebrza − a small, lowland, low dynamic European river located in Northeast Poland.
