Thanks to NASA's Coastal Zone Color Scanner (CZCS, 1978-1986), nearly ocean-wide coverage of the distribution of phytoplankton pigment in the upper part of the euphotic zone and, in effect, in the mix...
Observation of aquatic animals in their natural environments remains a major challenge in both biological oceanography and limnology. Critical processes in feeding, reproduction, growth, and predation...
Understanding the dynamics of the relationship between phytoplankton and higher trophic levels is necessary for understanding the transfers of matter and energy through planktonic food webs. There hav...
Recent findings from oceanographic field studies conducted on both sides of the North Atlantic have dramatically altered our view of how zooplankton populations respond to climate-driven changes in oc...
The 20-year US GLOBEC (Global Ocean Ecosystem Dynamics) program examined zooplankton populations and their predators in four coastal marine ecosystems. Program scientists learned that environmental co...
Logistical challenges, time, and the cost of towed net surveys make it difficult to obtain estimates of secondary biomass and production in the open ocean outside the summer sampling season. Alternate...
We examined 20 yr of zooplankton samples from Harp Lake for shifts in zooplankton variability following invasion by zooplankton predator Bythotrephes longimanus, using organism body size—as measured a...
Nitrogen isotopic compositions of zooplankton in the California Current Ecosystem (CCE) are known to vary over inter-annual scales of climate variability, but the extent to which those changes are dri...
We used amino acid (AA) compound-specific isotope analysis (d15NAA and d13 CAA values) of midwater zooplankton and suspended particles to examine their dynamics in the mesopelagic zone. Suspended pa...
Contrary to the suggestion that swarming can be used as an antipredation defense in zooplankton, the individual risk of a planktonic prey (Daphnia) increased rather than decreased with prey density u...
I compiled literature on zooplankton body composition, from protozoans to gelatinous plankton, and report allometric relations and average body composition. Zooplankton segregate into gelatinous and ...
Sinking particulate material collected in sequencing sediment traps moored at 3500 m depth (600 m above bottom) from 1993 to 2008 at the abyssal time-series Sta. M in the northeast Pacific was analyz...
Using a combined stable-isotope and fatty-acid approach, we examined carbon-transfer routes from the cyanobacterium Microcystis to zooplankton in eutrophic Lake Taihu, China. Microcystis is generally ...
Eurytemora affinis (Copepoda) were fed 15N-labeled Rhodomonas salina (Cryptophyta) or 15N-labeled Nodularia spumigena (Cyanobacteria) in excess under controlled laboratory conditions. Zooplankton col...
Using a combined stable-isotope and fatty-acid approach, we examined carbon-transfer routes from thecyanobacteriumMicrocystisto zooplankton in eutrophic Lake Taihu, China.Microcystisis generally consi...
