Reef fishes of Saba Bank, Netherlands Antilles : Assemblage structure across a gradient of habitat types [PDF]

open access: yes, 2010
Saba Bank is a 2,200 km2 submerged carbonate platform in the northeastern Caribbean Sea off Saba Island, Netherlands Antilles. The presence of reef-like geomorphic features and significant shelf edge coral development on Saba Bank have led to the ...

Cenomanian – Coniacian zonation (foraminifers and calcareous algae) in the Guerrero – Morelos basin, southern Mexico

open access: yesRevista Mexicana de Ciencias Geológicas, 2018
A biostratigraphic zonation of the Cenomanian–Coniacian rocks of the Guerrero–Morelos basin (southern Mexico) is proposed. The stratigraphic distribution of 70 species of calcareous algae and benthic and planktonic foraminifers is used to characterize ...

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

open access: yes, 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 ...

Short-term fate of phytodetritus in sediments across the arabian sea oxygen minimum zone [PDF]

open access: yes, 2007
The short-term fate of phytodetritus was investigated across the Pakistan margin of the Arabian Sea at water depths ranging from 140 to 1850 m, encompassing the oxygen minimum zone (~100–1100 m).

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 ...

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

Benthic and interstitial habitats of a lentic spring as invertebrate refuges during supra-seasonal drought [PDF]

open access: yes, 2013
Instream refuges are places where invertebrates persist during disturbances due to reduced adverse impacts. During droughts, low flows may be accompanied by elevated temperatures, and potential refuges including subsurface sediments and spring-fed ...

Benthic Dinitrogen Fixation Traversing the Oxygen Minimum Zone Off Mauritania (NW Africa) [PDF]

open access: yesFrontiers in Marine Science, 2017
Despite its potential to provide new nitrogen (N) to the environment, knowledge on benthic dinitrogen (N2) fixation remains relatively sparse, and its contribution to the marine N budget is regarded as minor. Benthic N2 fixation is often observed in organic-rich sediments coupled to heterotrophic metabolisms, such as sulfate reduction.

Temporal variability of benthic macrofauna on Cassino beach, southernmost Brazil

open access: yesIheringia: Série Zoologia, 2008
The temporal variability of benthic macrofauna on Cassino beach, southernmost Brazil, was studied for a period of one year (June 2004 to May 2005) based on monthly sampling. Three sites were selected distant 50m from each other. At each site, 3 transects

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 ...
