Food web complexity alters phytoplankton persistence and resilience to nutrient pulses in experimental ecosystems

open access: yesLimnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract In aquatic ecosystems, greater food web complexity is theorized to increase persistence and resilience of primary production to pulse disturbances, yet experimental evidence is limited. We simulated two storm‐induced pulse disturbances by adding nutrients (~ 3%–5% increase in ambient concentrations) to three ponds with low, intermediate, and ...

Linking stage-resolved population models with field observations: an integrated approach on population dynamics of Pseudocalanus elongatus in the German Bight. [PDF]

open access: yes, 2012
The population dynamics of Pseudocalanus elongatus have been investigated within the framework of the GLOBEC-Germany project to gain a better understanding of its life cycle and population dynamics and to estimate secondary production in the North Sea.

Invertebrate communities in northern Lake Victoria, with reference to their potential for fishery production [PDF]

open access: yes, 1999
The zooplankton and macrobenthic communities of Lake Victoria were sampled by lift net and Ponar grab, respectively. The zooplankton comprised copepods and cladocerans, rotifers and aquatic insect larvae. Most taxa exhibited wide distribution in the lake,

Seasonal prey taxa and size selection and drivers of age-0 walleye ontogenetic diet shifts

open access: yesJournal of Freshwater Ecology
Prey abundance and size vary seasonally, creating a dynamic connection between predator and prey. The natural complexity related to consuming multiple prey types as fish undergo ontogenetic diet shifts combined with the frequent sampling and substantial ...

Elevated carbon dioxide can boost freshwater zooplankton abundance, while warming may shift community composition, weakening phytoplankton control

open access: yesLimnology and Oceanography, Volume 70, Issue S2, Page S273-S288, December 2025.
Abstract Zooplankton communities in ponds and lakes control phytoplankton growth and serve as a food source for higher trophic levels such as fish. Recent experiments have shown that several freshwater zooplankton species as well as the phytoplankton communities on which they feed can be variably affected by rising temperatures, reduced pH and higher ...

New Diaptomidae records (Crustacea: Copepoda: Calanoida: Diaptomidae) in the Neotropical region [PDF]

open access: yesCheck List, 2013
TIn this study we present 208 new diaptomids records, including 36 species from 10 genera. They are the result of new samplings as well as of the revision of samples from previous surveys from various localities in the Neotropical Region.

Patterns and Processes of Groundwater Invasion by Copepods in the Interior Low Plateaus of the United States

open access: yesActa Carsologica, 2007
The copepod crustacean fauna collected from subterranean habitats, including caves, wells, and the hyporheos of streams in and near the Interior Low Plateaus of the United States is dominated by Cyclopoida, with 39 species, followed by Harpacticoida with
