Resolving abrupt frontal gradients in zooplankton community composition and marine snow fields with an autonomous Zooglider

Limnology and Oceanography, EarlyView.
Abstract An autonomous Zooglider navigated across the California Current Front into low salinity, minty waters characteristic of the California Current proper in both summers of 2019 and 2021. Diving to 400 m depth, Zooglider transited another near‐surface frontal gradient somewhat inshore. These frontal gradients were generally associated with changes

Nutrient pulse scenarios drive contrasting patterns in the functional stability of freshwater phytoplankton

Limnology and Oceanography, EarlyView.
Abstract Climate change is increasing the frequency, intensity, and stochasticity of extreme weather events such as heavy rainfall, storm‐induced mixing, or prolonged drought periods. This results in more variable regimes of dissolved nutrients and carbon in lakes and induces temporal fluctuations in the resource availability for plankton communities ...

Algal food identity affects morphological anti‐predatory defense in Daphnia pulex

Limnology and Oceanography, EarlyView.
Abstract Microcrustaceans of the genus Daphnia have evolved various inducible anti‐predator defenses; however, it is largely underexplored how the bottom‐up factor food quality may affect the extent of these defenses. A well‐studied example of an inducible defense is the deployment of neckteeth in Daphnia pulex in response to infochemicals from ...

Co‐occurrence and successional patterns among diatoms, dinoflagellates, and potential parasites in a coastal upwelling experiment

Limnology and Oceanography, EarlyView.
Abstract Diatom‐dominated blooms in coastal upwelling systems contribute disproportionately to global primary production. The fate of carbon captured during a diatom bloom is often influenced by species‐specific ecological differences. However, successional patterns that take place during a diatom bloom are often oversimplified, and the diversity of ...
