Squid as nutrient vectors linking Southwest Atlantic marine ecosystems

Stable isotope (δ18O and δ13C) sclerochronology of Callovian (Middle Jurassic) bivalves (Gryphaea (Bilobissa) dilobotes) and belemnites (Cylindroteuthis puzosiana) from the Peterborough Member of the Oxford Clay Formation (Cambridgeshire, England): Evidence of palaeoclimate, water depth and belemnite behaviour

“…are also reported to migrate (Rexfort and Mutterlose, 2006). Some recent papers have explained unexpectedly cool belemnite palaeotemperatures as being the result of salinity effects (Mutterlose et al, 2010;2012). Scheurle and Hebbeln (2003) However, such an explanation is unlikely to account for the cool belemnite temperatures recorded here.…”

“…Dutton et al, 2007;Wierzbowski and Joachimski, 2009;Price et al, 2012), and in studies where average belemnite δ 18 O palaeotemperatures were lower than those derived from proxies believed to represent SSTs, e.g. TEX 86 (Mutterlose et al, 2010;2012) In the present case, depth of belemnite habitat alone cannot explain the significant offset in the temperature minima between belemnites and benthos revealed here by incremental analyses. In order to record minimum temperatures of 11°C without migrating laterally, C.…”

“…Significantly, both scenarios suggest that migration over significant distances occurred. Such movements are plausible when one considers that the modern squid Illex argentinus traverses large latitudinal ranges in the shelf seas off South America (Arkhipkin, 2012), whilst Sepia sp. are also reported to migrate (Rexfort and Mutterlose, 2006).…”

Water density pathways for shelf/slope migrations of squid Illex argentinus in the Southwest Atlantic

“…During their short (mostly annual) life cycle, these squid are able to move thousands of kilometres between their spawning and feeding grounds often located in different temperate zones of the world's oceans (Arkhipkin, 2013). One of the typical representatives of these migrants is the Argentine short-finned squid Illex argentinus.…”

Population dynamics of the squids Dosidicus gigas (Oegopsida: Ommastrephidae) and Doryteuthis gahi (Myopsida: Loliginidae) in northern Peru

“…This is potentially associated with the different life history strategies of ommastrephid and loliginid squids. These differing life history characteristics include the type of spawning, the related dispersal potential (O'Dor and Webber, 1991;Boyle and Rodhouse, 2005), as well as the squid habitat use (see Arkhipkin, 2013). Loliginid squids inhabit coastal areas and their populations are likely to be affected by local or mesoscale variations of ENSO.…”
