The ocean's distinctive smell is caused by a single chemical released by plankton and other marine life, dimethyl sulphide (DMS). A study by a group of investigators from the University of Groningen used a technique called laser-sheet particle image ...

Identification of microzooplankton seasonally using time series analysis [PDF]
Seasonal changes in microzooplankton abundance were identified in the mesohaline Chesapeake Bay and several tributaries from July 1992 through December 1995. Ciliates numerically dominated, comprising over 90% of the total microzooplankton density and aloricate ciliates usually outnumbered loricate ciliates.

Phosphorus limitation drives seasonal enlargement of the coccosphere size in two coccolithophores
Abstract Coccolithophores are abundant marine microalgae that produce a cell cover (coccosphere) composed of calcium carbonate platelets (coccoliths), and that play a unique role in the global carbon cycle. Gephyrocapsa huxleyi is the most prevalent coccolithophore in the oceans. Experiments in vitro indicate that the coccosphere size in G.

Coupling the PLANKTOM5.0 marine ecosystem model to the OCCAM 1º ocean general circulation model for investigation of the sensitivity of global biogeochemical cycles to variations in ecosystem complexity and physical environment [PDF]
The earliest marine ecosystem models consisted of a simple representation of the main features of marine ecosystems, including, typically, variables for phytoplankton, zooplankton, nutrient and detritus (NPZD models).

Effect of zooplankton-mediated trophic cascades on marine microbial food web components (bacteria, nanoflagellates, ciliates) [PDF]
To examine the grazing effects of copepod-dominated mesozooplankton on heterotrophic microbial communities, four mesocosm experiments using gradients of zooplankton abundance were carried out at a coastal marine site.

Oceanographic heterogeneity facilitates gelatinous zooplankton niche space and diversity
Abstract Gelatinous zooplankton serve diverse ecological roles in shelf food webs—from grazers to predators. However, their spatial niches are poorly resolved, especially at detailed taxonomic levels, due to conventional techniques that are unable to measure distributions at fine spatial scales.

Generalized Lévy walks and the role of chemokines in migration of effector CD8+ T cells. [PDF]
Chemokines have a central role in regulating processes essential to the immune function of T cells, such as their migration within lymphoid tissues and targeting of pathogens in sites of inflammation.

Widespread Phenological Shifts With Temperature in Alaska's Marine Fishes
We investigated changes in the phenology of early life stages of fishes in the Gulf of Alaska and Bering Sea. Larval size on a standardized date was used as a proxy for larval developmental timing in spring. For most species, interannual variation in mean size‐at‐date was significantly and positively related to temperature, demonstrating widespread ...

Seasonal modulation of mesoscale processes alters nutrient availability and plankton communities in the Red Sea [PDF]
Hydrographic and atmospheric forcing set fundamental constraints on the biogeochemistry of aquatic ecosystems and manifest in the patterns of nutrient availability and recycling, species composition of communities, trophic dynamics, and ecosystem ...

Predation on naked protozoan microzooplankton by fish larvae [PDF]
To evaluate the role of fish larvae as a link between the microbial loop and higher trophic levels, predation of protozoan zooplankton by young larvae was investigated. More than 400 individual fish larvae with total lengths of less than ca 10 mm in 52 different taxonomic groups were collected at different sampling times from several coastal regions ...
