Spatial distribution and secondary production of Copepoda in a tropical reservoir: Barra Bonita, SP, Brazil

Brazilian Journal of Biology
The present paper aims to describe the spatial distribution of zooplankton copepods, their biomass and instantaneous secondary production, in Barra Bonita, a large eutrophic, polymitic reservoir (22° 29' S and 48° 34' W) on the Tietê River, of the Paraná

The IceShark, an effective method for sampling plankton under sea ice

Limnology and Oceanography: Methods, Volume 24, Issue 4, April 2026.
Abstract Seasonal sea ice plays a crucial role in shaping coastal ecosystem dynamics throughout the circumpolar region. Of particular interest to oceanographers is the ice‐ocean interface which functions as a multidimensional habitat, supporting both sympagic algae and pelagic phytoplankton in the under‐ice surface waters.

First record of a representative of the subfamily Paradiaptominae (Copepoda Calanoida Diaptomidae) in Italy: Metadiaptomus chevreuxi (Guerne & Richard, 1894)

Journal of Limnology, 2005
Metadiaptomus chevreuxi (Guerne & Richard 1894), a diaptomid calanoid copepod belonging to the subfamily Paradiaptominae, has been found in two neighbouring temporary pools in the Egadi Archipelago (Sicily, southern Italy).

Blastodinium spp. infect copepods in the ultra-oligotrophic marine waters of the Mediterranean Sea [PDF]

Biogeosciences, 2011
Blastodinium are chloroplast-containing dinoflagellates which infect a wide range of copepods. They develop inside the gut of their host, where they produce successive generations of sporocytes that are eventually expelled through the anus of the copepod.

Predicting oxygen thresholds of marine taxa to improve ecological forecasts

Ecography, Volume 2026, Issue 3, March 2026.
Species' ranges are shifting in response to increasing temperature and decreasing oxygen in coastal oceans. Predicting these shifts is limited by information on physiological oxygen thresholds and how they depend on temperature. Here we collate laboratory‐derived measurements of a common oxygen threshold, pcrit, for 148 animal species that span six ...

Net phytoplankton and zooplankton in the New York Bight, January 1976 to February 1978, with comments on the effects of wind, Gulf Stream eddies, and slope water intrusions [PDF]

, 1984
Results are given of monthly net phytoplankton and zooplankton sampling from a 10 m depth in shelf, slope, and Gulf Stream eddy water along a transect running southeastward from Ambrose Light, New York, in 1976, 1977, and early 1978.

First record of Hemidiaptomus (Gigantodiaptomus) superbus (Schmeil, 1895) in Italy, with notes on distribution and conservation status (Copepoda, Calanoida, Diaptomidae) [PDF]

, 2011
Hemidiaptomus (Gigantodiaptomus) superbus (Schmeil, 1895) was found in a temporary pool in the Pineta di Classe coastal pine-wood (Ravenna, northern Italy).

Environmental DNA Reveals Diverse and Depth‐Stratified Biodiversity in East Indian Ocean Submarine Canyons

Environmental DNA, Volume 8, Issue 2, March/April 2026.
Environmental DNA metabarcoding reveals diverse animal communities across Cape Range and Cloates submarine canyons off Western Australia. Two assays detected 234 species spanning 125 families across 11 phyla, highlighting canyon‐specific assemblages and demonstrating the value of eDNA for establishing biodiversity baselines in remote and poorly ...

Copepod fauna (Calanoida and Cyclopoida) in small ponds of the Pollino National Park (South Italy), with notes on seasonality and biometry of species

Journal of Limnology, 2006
The plankton copepod fauna of the Pollino National Park (South Italy) were studied for the first time. Plankton samples were collected from 5 ponds, and 2 of these ponds were sampled monthly for one year to study species’ seasonality. The length of adult

Overlooked cryptic endemism in copepods: Systematics and natural history of the calanoid subgenus Occidodiaptomus Borutzky 1991 (Copepoda, Calanoida, Diaptomidae) [PDF]

, 2013
Our comprehension of the phylogeny and diversity of most inland–water crustaceans is currently hampered by their pronounced morphological bradytely, which contributed to the affirmation of the ‘‘Cosmopolitanism Paradigm’’ of freshwater taxa.
