Trophic Groups Of Demersal Fish Of Santos Bay And Adjacent Continental Shelf, São Paulo State, Brazil: Temporal And Spatial Comparisons

Brazilian Journal of Oceanography, 2014
The temporal and spatial variations of feeding habits and trophic groups of demersal fish species of Santos Bay and the adjacent continental shelf were investigated. The samples were taken in September 2005 and March 2006 by bottom otter trawling.

Diagenetic controls on porosity evolution and pore type organisation in microporous carbonate rocks: Evidence for mesogenetic porosity formation

Sedimentology, Volume 73, Issue 6, Page 2353-2380, October 2026.
ABSTRACT Microporous carbonate rocks typically record complex diagenetic histories driven by microbial activity and fluid interactions within multiple diagenetic environments. The relative roles of meteoric and burial diagenetic processes in pore evolution remain debated, particularly within Cretaceous carbonate systems of the Middle East, as does the ...

Sulfated Polyhydroxysteroids from the Antartic Ophiuroid Gorgonocephalus Chilensis [PDF]

Molecules, 2000
Five disulfated steroids and a mixture of monosulfated steroids were isolated from the ethanolic extract of the antarctic ophiuroid Gorgonocephalus chilensis. The structures were determined by 1H-NMR, 13C-NMR and FABMS.

Limited connectivity of zooplankton communities across the Labrador Front: role of physical oceanography, insights from individual motility

Oikos, Volume 2026, Issue 8, August 2026.
Near the western margin of the highly productive Labrador Sea, the Labrador Current creates a large and steep oceanographic front between the Arctic‐origin shelf waters and the Atlantic offshore waters (i.e. the Labrador Front), presumably segregating or accumulating plankton communities.

DNA Barcoding of Cold-Water Coral-Associated Ophiuroid Fauna from the North Atlantic

Diversity, 2022
In this study we focus on the ophiuroid species associated with cold-water corals south of Iceland. The specimens were sampled with the ROV Phoca (GEOMAR) in three different areas, during the recent expedition MSM75 connected to the IceAGE_RR (Icelandic ...

Evidence of Cheliped Autotomy and Regeneration in the Lower Miocene Crab Achelous monspeliensis From Portugal

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Crab autotomy with evidence of regeneration is described for the first time in the fossil record. Autotomy is a defensive behavior that affects more males than females of Achelous monspeliensis and may be related to mating season. ABSTRACT Autotomy—the voluntary shedding of a limb as a defensive response to predation, intraspecific aggression, or ...
