A quantitative analysis of the phytoplankton of the Gulf of Panama II. On the relationship between C14 assimilation and the diatom standing crop [PDF]

, 1965
ENGLISH: The Inter-American Tropical Tuna Commission has maintained a hydro-biological station in the Gulf of Panama located at 8°45'N, 79°23'W in connection with their ecological investigation of the anchoveta (Cetengraulis mysticetus), a tuna baitfish (

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

Limnology and Oceanography, EarlyView.
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 ...

Using stable isotopes to describe the trophic structure of gelatinous zooplankton across the deep pelagic

Limnology and Oceanography, EarlyView.
Abstract Although gelatinous zooplankton are key members of marine ecosystems and food webs, their trophic ecology is poorly described across the deep pelagic. We used stable carbon (bulk tissue) and nitrogen (bulk tissue and amino acid) isotope analysis to estimate the trophic positions (TPs) of abundant gelatinous zooplankton (chaetognaths ...

Spatial dynamics of animal‐mediated nutrients in temperate waters

Limnology and Oceanography, EarlyView.
Abstract Consumer‐mediated nutrient dynamics (CND), through which animals' metabolic waste products fertilize primary producers, drive variability in nutrient availability in tropical waters. This variability influences primary productivity and community functioning.

Evaluation of climate change scenarios based on aquatic food web modelling [PDF]

, 2008
In the years 2004 and 2005 we collected samples of phytoplankton, zooplankton and macroinvertebrates in an artificial small pond in Budapest. We set up a simulation model predicting the abundance of the cyclopoids, Eudiaptomus zachariasi and Ischnura ...

Significant impact of lithogenic dissolution from subantarctic volcanic islands on the regional marine silicon cycle

Limnology and Oceanography, EarlyView.
Abstract Silicic acid controls the production of diatoms, a predominant phytoplankton in the Southern Ocean. Diatoms are major contributors to the biological carbon pump, which is particularly active in the Southern Ocean as well as in areas naturally enriched in iron, such as around the Kerguelen Plateau.

Localized and episodic enhancement of net community production and phytoplankton carbon in spring and summer at the Northeastern US shelf‐break front

Limnology and Oceanography, EarlyView.
Abstract The shelf‐break front of the Mid‐Atlantic Bight (MAB) is hypothesized to cause increased biological productivity but observations of such enhancement have been scarce. Additionally, most previous studies at the MAB are based on chlorophyll rather than on actual observed rates of production.

Biogeochemical Markers to Identify Spatiotemporal Gradients of Phytoplankton across Estuaries

Coasts
The spatiotemporal distribution of phytoplankton in estuaries is indicative of processes and transport across the land–ocean aquatic continuum (LOAC). Estuaries, as biogeochemically and physically active systems, process large amounts of nutrients and ...
