Oceanographic heterogeneity facilitates gelatinous zooplankton niche space and diversity

Limnology and Oceanography Letters, Volume 11, Issue 1, January 2026.
Abstract Gelatinous zooplankton serve diverse ecological roles in shelf food webs—from grazers to predators. However, their spatial niches are poorly resolved, especially at detailed taxonomic levels, due to conventional techniques that are unable to measure distributions at fine spatial scales.

Arctic‐breeding black‐legged kittiwakes show individual variation in foraging responses to glacial conditions without consequences for reproductive output

Oikos, Volume 2026, Issue 1, January 2026.
Behavioural plasticity is likely to influence how individuals continue to access resources under rapid climate change. Plasticity will be particularly important at highly dynamic, prey‐rich foraging areas such as upwelling fronts of marine‐terminating glaciers in the high Arctic, where profitability varies significantly across space and time ...

Diurnal variations in the vertical distribution and abundance of zooplankton in the continental shelf waters off Cochin during April 1991 [PDF]

, 1996
The present study is based on zooplankton samples collected by vertical hauls from 0-30, 30-60 and 60-90 m depths from a 100 m depth station in the continental shelf (09° 44' N, 75° 42*8) off Cochin for two days at three hourly interval.

Dissolved and Particulate Methylated Mercury in a Highly Productive Area of the Southern Ocean

Global Biogeochemical Cycles, Volume 40, Issue 1, January 2026.
Abstract Methylated mercury (MeHg), including dimethylmercury and monomethylmercury (MMHg), is a pollutant of concern because it biomagnifies in marine biota. The formation of MeHg in the oceans, specifically at highly productive regions and at high oxygen levels, remains elusive.

Studies on chaetognaths off Ubatuba region, Brazil: II. Feeding habits

Brazilian Journal of Oceanography, 1995
The diet of chaetognath species were studied by examining the gut contents of 9466 specimens collected off Ubatuba region, São Paulo State. The greatest proportion of chaetognaths (7119 individuals) showed their gut contents empty. Copepods, mollusc eggs,

Trophic ecology of carnivorous zooplankton in the Benguela [PDF]

, 1992
Carnivorous zooplankton in the Benguela system have tended to be ignored by all but early taxonomists and a handful of recent researchers. An attempt is made here to address the importance of carnivores in this system but, because the database is poor ...
