The subtropical gyres occupy approximately 40% of the surface of the Earth and are widely recognized as oligotrophic zones. Among them, the South Pacific subtropical gyre (SPSG) shows the lowest chlorophyll-a levels (0.02–0.04 μgL–1), the deepest ...

The zooplankton assemblages in Chilean Patagonian lakes are characterised mainly by their low biodiversity and high predominance of calanoids copepods, a pattern that has been studied for large and deep lakes between 38-51° S, and shallow ponds at 51° S.

The Humboldt Current System (HCS) is a highly dynamic upwelling system implying a strongly variable environment for zooplankton inhabiting the coastal zone.

Choreographed swimming of copepod nauplii [PDF]
Small metazoan paddlers, such as crustacean larvae (nauplii), are abundant, ecologically important and active swimmers, which depend on exploiting viscous forces for locomotion. The physics of micropaddling at low Reynolds number was investigated using a model of swimming based on slender-body theory for Stokes flow.

Monsoon effects on the copepod community structure in the Chabahar Bay, Oman Sea
Calanoid, cyclopoid, harpacticoid and poecilostomatoid copepods were investigated over the year at five stations in the Chabahar Bay, Oman Sea. This area is under the influence of the Indian Ocean seasonal monsoons.

Arctic copepod copper sensitivity and comparison with Antarctic and temperate copepods
AbstractThe ongoing global climate crisis increases temperatures in polar regions faster and with greater magnitude than elsewhere. The decline of Arctic sea ice opens up new passages, eventually leading to higher anthropogenic activities such as shipping, fishing, and mining.

Prey detection in a cruising copepod [PDF]
Small cruising zooplankton depend on remote prey detection and active prey capture for efficient feeding. Direct, passive interception of prey is inherently very inefficient at low Reynolds numbers because the viscous boundary layer surrounding the approaching predator will push away potential prey. Yet, direct interception has been proposed to explain

Zooplankton, particularly copepods, are key components in aquatic food webs. However, the effects of ultraviolet (UV) radiation on copepods in marine systems, especially at tropical and subtropical latitudes, are not well understood.

Grazing by zooplankton can regulate bloom-forming cyanobacteria but can also transfer toxin-producing cells, as well as toxic metabolites, to the food web.

Biological effects of El Niño 1997-98 on a shallow subtropical ecosystem: Bahía Magdalena, Mexico [PDF]
Sea surface temperature (SST), zooplankton biomass and chlorophyll a concentration, along with abundance of four copepod species: Acartia clausi, Acartia lilljeborgii, Paracalanus parvus and Calanus pacificus, and eggs and larvae of small pelagic fishes:
