Nutritional grouping of marine forage species reveals contrasted exposure of high trophic levels to essential micro‐nutrients

open access: yesOikos, Volume 2022, Issue 7, July 2022., 2022
By transferring energy and nutrients from plankton to top predators, forage species play a major ecological role in marine food webs. While large differences in energy densities have been demonstrated among these species, other determinants of their quality remain poorly explored.

Sampling Frame for Mediterranean and Black Sea CFP Monitoring indicators [PDF]

open access: yes, 2017
The Mediterranean and Black Sea list of stocks to be used for computing the indicators was based on a ranking system approach for which the species having a rank in the first ten positions either in total live weight or total economic values were chosen.

Cephalopods in the diet of Risso's dolphin (Grampus griseus) from the Mediterranean Sea: A review

open access: yesMarine Mammal Science, Volume 38, Issue 2, Page 725-741, April 2022., 2022
Abstract The Risso's dolphin, Grampus griseus, is a deep‐sea cetacean with a predominantly teuthophagous diet. Its distribution in the northwest Mediterranean is generally in deeper waters, but there is little information on diet or feeding areas. To extend knowledge of the diet of G.

An ethogram for Benthic Octopods (Cephalopoda: Octopodidae).

open access: yesJournal of Comparative Psychology, 2016
The present paper constructs a general ethogram for the actions of the flexible body as well as the skin displays of octopuses in the family Octopodidae. The actions of 6 sets of structures (mantle-funnel, arms, sucker-stalk, skin-web, head, and mouth) combine to produce behavioral units that involve positioning of parts leading to postures such as the

Ultra-fast escape maneuver of an octopus-inspired robot [PDF]

open access: yes, 2014
We design and test an octopus-inspired flexible hull robot that demonstrates outstanding fast-starting performance. The robot is hyper-inflated with water, and then rapidly deflates to expel the fluid so as to power the escape maneuver.
