Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 7, July 2026.ABSTRACT The bluntnose sixgill shark (Hexanchus griseus) is classified as ‘Near Threatened’ at a global level but currently holds a ‘Least Concern’ status in the Mediterranean Sea, despite increasing fishing pressure and insufficient data. This study presents the first comprehensive stock assessment of H. griseus in north‐eastern Tunisia (GFCM GSA 13),

Vertical distribution of Baltic sprat larvae: changes in patterns of diel migration? [PDF]
, 2007 Ontogenetic and diurnal vertical migration patterns of Baltic sprat larvae were investigated for the periods 1989–1990 and 1998–2002. Comparison of the results led to the hypothesis that the diel vertical migration behaviour of sprat larvae >10 mm has ...

The Importance of Mesozooplankton Diel Vertical Migration for Sustaining a Mesopelagic Food Web
Frontiers in Marine Science, 2019 We used extensive ecological and biogeochemical measurements obtained from quasi-Lagrangian experiments during two California Current Ecosystem Long-Term Ecosystem Research cruises to analyze carbon fluxes between the epipelagic and mesopelagic zones ...

The Plasticity of the Antioxidant Defence System of Coastal Zooplankton Communities
Ecology and Evolution, Volume 16, Issue 7, July 2026.In this photo, a copepodite Acartia spp. is represented with Vorticella epiphytes. This photo was taken with the help of a PlanktoScope, which belongs to the Hellenic Centre for Marine Research. Photographer: Andriana Koutsandrea. ABSTRACT Zooplankton are expected to enhance their antioxidant defences and activate stress‐related biomarkers in response ...

Diel vertical migration patterns in juvenile cod from the Skagerrak coast [PDF]
, 2010 We demonstrated a clear year-round diel vertical migration pattern (DVM) of small (26 to 45 cm) Skagerrak coastal cod Gadus morhua on a small geographic scale.

The nightscape of the Arctic winter shapes the diving behavior of a marine predator
Scientific ReportsPredator–prey interactions in marine ecosystems are dynamically influenced by light, as demonstrated by diel vertical migrations of low-trophic level organisms.

Diel and Artificial Light Effects on Nearshore Communities Revealed by eDNA Metabarcoding
Environmental DNA, Volume 8, Issue 4, July‐August 2026.Environmental DNA revealed rapid, taxon‐specific community reorganization across diel and artificial light conditions in a nearshore marine ecosystem. Distinct responses among trophic groups indicate that artificial light at night reshapes predator–prey interactions and community structure within 30 min of exposure.

Light-induced swimming of Daphnia: can laboratory experiments predict diel vertical migration? [PDF]
, 1997 Vertical displacement velocity of a Daphnia galeata x hyalina clone was quantified in relation to changes in the relative rate of light change. An increase in the latter variable triggers an enhanced swimming response, and this response is again elicited
