Growth and reproductive rates of the dominant copepod Pseudodiaptomus forbesi in response to environmental factors and habitat type in the northern San Francisco Estuary

Autor: Anne M. Slaughter, Wim J. Kimmerer, Toni R. Ignoffo, Austin J. Gearty

Publikováno v: Aquatic Ecology. 55:825-848

We examined growth and egg production rates of Pseudodiaptomus forbesi (Copepoda: Calanoida) in the northern San Francisco Estuary (SFE), California, USA. Data from several earlier studies were combined with new data to assess the responses of these

Publikováno v: Estuaries and Coasts. 44:1083-1099

In 2016, a massive bloom of the chain-forming diatom Aulacoseira granulata occurred in the upper San Francisco Estuary, California, with chlorophyll concentrations up to 75 μg Chl L−1. In this study, quantitative PCR was used to investigate consum

Publikováno v: Journal of Plankton Research. 41:939-954

We measured growth rates of the copepod Pseudodiaptomus forbesi in relation to food, environmental conditions and hydrology in the northern San Francisco Estuary, California, USA. We conducted 38 copepod growth-rate experiments during summers 2015–

Effects of freshwater flow and phytoplankton biomass on growth, reproduction, and spatial subsidies of the estuarine copepod Pseudodiaptomus forbesi

Autor: Anne M. Slaughter, Karen Kayfetz, Toni R. Ignoffo, Wim J. Kimmerer

Publikováno v: Hydrobiologia. 807:113-130

We examined how freshwater flow and phytoplankton biomass affected abundance and population dynamics of the introduced subtropical copepod Pseudodiaptomus forbesi in brackish and freshwater regions of the San Francisco Estuary, California, USA. This

Prey selection of larval and juvenile planktivorous fish: impacts of introduced prey

Autor: Bradd Baskerville-Bridges, Wim J. Kimmerer, Toni R. Ignoffo, David J. Ostrach, Lindsay J. Sullivan

Publikováno v: Environmental Biology of Fishes. 99:633-646

Changes in the abundance and composition of zooplankton resulting from species introductions may be contributing to a decline in the abundance of planktivorous fish in the San Francisco Estuary (SFE). To examine how changes in the prey assemblage may

Food-limited reproduction and growth of three copepod species in the low-salinity zone of the San Francisco Estuary

Autor: Toni R. Ignoffo, Anne M. Slaughter, Wim J. Kimmerer, Alison L. Gould

Publikováno v: Journal of Plankton Research. 36:722-735

We determined reproductive and growth rates of three common copepods in the low-salinity zone of the San Francisco Estuary during spring-summer of 2006 and 2007. Rates were low, particularly during summer. The egg production rate of Eurytemora affini

Feeding capabilities and limitations in the nauplii of two pelagic estuarine copepods, Pseudodiaptomus marinus and Oithona davisae

Autor: Jonathon H. Stillman, Robert A. Vogt, Wim J. Kimmerer, Julian Herndon, Lindsay J. Sullivan, Toni R. Ignoffo

Publikováno v: Limnology and Oceanography. 58:2145-2157

In most aquatic ecosystems, copepod nauplii outnumber all other mesozooplankton. Although thousands of studies have examined feeding by later life history stages, the feeding habits of nauplii are poorly known. We offered conspecific adult and naupli
