Divergent patterns of zooplankton connectivity in the epipelagic and mesopelagic zones of the eastern North Pacific [PDF]
Ecology and Evolution, 2023 Due to historical under‐sampling of the deep ocean, the distributional ranges of mesopelagic zooplankton are not well documented, leading to uncertainty about the mechanisms that shape midwater zooplankton community composition.

Studying of <i>Trachurus trachurus</i> (Linnaeus, 1758) Population Reproductive Dynamics in the Eastern Moroccan Mediterranean. [PDF]
Ecol EvolHorse mackerel (Trachurus trachurus) populations along the eastern Moroccan Mediterranean coast were studied over 12 months using 390 specimens to assess reproductive ecology. The species showed two spawning periods—late winter to early spring and summer—and exhibited fractional spawning, with males being more predominant.

Large-scale metabarcoding analysis of epipelagic and mesopelagic copepods in the Pacific.
PLoS ONE, 2020 A clear insight into the large-scale community structure of planktonic copepods is critical to understanding the mechanisms controlling diversity and biogeography of marine taxa in terms of their high abundance, ubiquity, and sensitivity to environmental

Vertical distribution of zooplankton in the epipelagic zone off Sharm El-Sheikh, Red Sea, Egypt
Oceanologia, 2012 The purpose of the present study was to track the seasonal vertical distribution of zooplankton abundance in the epipelagic zone off Sharm El-Sheikh, Red Sea. Zooplankton samples were collected seasonally within the depth ranges of 0-25, 25-50, 50-75, 75-

Pelagic cnidarian assemblages show range-edge effect at the boundary of ocean surface, as illustrated in the case of the Amazon River Plume. [PDF]
PLoS ONEThe neuston layer represents a complex community inhabiting the interface where oceanographic and atmospheric processes interact. Here, our aim was to compare patterns in the distribution and abundance of cnidarian assemblages observed in the neuston to ...

ENSO modulates aerobic habitat across varying hypoxia tolerance levels in the Southeast Pacific throughout the twenty-first century [PDF]
Scientific ReportsThe ENSO (El Niño Southern Oscillation), the planet’s most consequential climate mode, imposes significant thermal stress on epipelagic marine ecosystems. However, its effects on aerobic habitats within the epipelagic and mesopelagic zones remain largely
