Breeding pelagic copepods [PDF]
Hydrobiological Bulletin, 1980 A cultivation technique has been developed to breed marine pelagic copepods for experimental purposes. Heterotrophic dinoflagellates occurring in the copepod cultures prevent the cultures from fouling due to sedimentation of autotrophic algae, administered daily from continuous cultures.

Parasites alter host community structure in a natural experiment
Journal of Animal Ecology, EarlyView.Parasites can alter host communities in complex ways, but empirical data from natural systems are rare. This study decomposes the effects of an invasive parasite on natural communities of fish in Trinidad, revealing the direct, indirect, and context dependence of the invasion on host demographic rates and community structure.

Invasive goldfish trigger a regime shift in experimental lake ecosystems of varying trophic state
Journal of Animal Ecology, EarlyView.The pet trade distributes exotic animals around the globe that enrich human lives. However, some pets become pests when released into the wild. This study provides experimental evidence that goldfish will negatively affect native freshwater organisms and ecosystems.

Possible Role of Fish and Frogs as Paratenic Hosts of Dracunculus medinensis, Chad
Emerging Infectious Diseases, 2016 Copepods infected with Dracunculus medinensis larvae collected from infected dogs in Chad were fed to 2 species of fish and tadpoles. Although they readily ingested copepods, neither species of fish, Nile tilapia (Oreochromis niloticus) nor fathead ...

Abundance, condition, and diet of juvenile Pacific ocean perch (Sebastes alutus) in the Aleutian Islands [PDF]
, 2009 T he relative value of pelagic habitat for three size classes of juvenile Pacific ocean perch (Sebastes alutus) was investigated by comparing their abundance and condition in two areas of the Aleutian Islands. Diet, zooplankton biomass, and water column

Geographic Patterns of Head Morphology in Syngnathus typhle Across Marine Regions
Integrative Zoology, EarlyView.Morphometric analysis of Syngnathus typhle head shape shows distinct geographic patterns across Baltic, North, Atlantic, and Mediterranean marine regions, driven by variation in snout length, head depth, and eye position. Findings provide a non‐invasive baseline for conservation monitoring.

Biological effects of El Niño 1997-98 on a shallow subtropical ecosystem: Bahía Magdalena, Mexico [PDF]
Geofísica Internacional, 2003 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:
