Offshore benthic habitat mapping based on object-based image analysis and geomorphometric approach. A case study from the Slupsk Bank, Southern Baltic Sea.

Science of the Total Environment, 2021
Benthic habitat mapping is a rapidly growing field of underwater remote sensing studies. This study provides the first insight for high-resolution hydroacoustic surveys in the Slupsk Bank Natura 2000 site, one of the most valuable sites in the Polish ...

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

Geological 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

The niche of benthic foraminifera, critical thresholds and proxies [PDF]

, 2001
Ecological studies of benthic foraminifera are carried out to explain patterns of distribution and the dynamics of communities. They are also used to provide data to establish proxy relationships with selected factors.

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

Geologica 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 ...

Low flow controls on benthic and hyporheic macroinvertebrate assemblages during supra-seasonal drought [PDF]

, 2009
Despite the widely accepted importance of the hyporheic zone as a habitat for stream macroinvertebrates during floods, few data exist regarding community composition and distribution during periods of low flow or drought in perennial streamsi ...

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

Limnology 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

Knowledge 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.

Environmental assessments for seabed impact and resilience from aquaculture: a case study in an intensive production area (Frøya, Norway)

Frontiers in Marine Science
Norway mandates protocols to manage salmon aquaculture’s impact on the seabed, with B-assessments for directly beneath the cages and C-assessments for the broader surrounding seabed with more chemical and biological variables. This study aimed to utilize

Half-life of biodegradable plastics in the marine environment depends on material, habitat, and climate zone

bioRxiv, 2021
The performance of the biodegradable plastic materials polyhydroxyalkanoate (PHA), polybutylene sebacate (PBSe) and polybutylene sebacate co-terephthalate (PBSeT), and of polyethylene (LDPE) was assessed under marine environmental conditions in a three ...
