Grazing and Zooplankton Production as Key Controls of Phytoplankton Production in the Open Ocean
Coast phytoplankton pigment waters physical oceanography
2015/8/17
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...
Ecology of a Chaetoceros socialis Lauder Patch on Georges Bank: Distribution, Microbial Associations, and Grazing Losses
Georges Bank: Distribution Microbial Associations
2015/8/6
The presence of patches and layers in marine pelagic ecosystems may play an important role in providing food for higher trophic levels at concentrations high enough to support the metabolism, growth, ...
Intense Benthic Grazing on Phytoplankton in Coral Reefs Revealed Using the Control Volume Approach
Coral Reefs Revealed Control Volume Approach
2015/8/5
What is our international investment in oceanography, and how has it changed over the years? Two seemingly simple questions that have daunted our community repeatedly. The first of these two questions...
Activity time budget patterns of sheep and goats co-grazing on semi-natural species-rich dry grassland
animal behaviour activity pattern small ruminant mixed pasture semi-natural grassland
2015/6/24
Activity time budget patterns and grazing response to sward and environmental conditions were investigated for paddocks of sheep and goats co-grazing for conservation purposes on a semi-natural specie...
Influence of Restricted Grazing Time Systems on Productive Performance and Fatty Acid Composition of Longissimus dorsi in Growing Lambs
Horse Breeding Show Jumping Variance Components
2016/5/18
Fifty 3-month-old male Tan lambs (similar in body weight) were divided into 5 groups to investigate the effects of different restricted pasture grazing times and indoor supplementation on the producti...
Effects of grazing on leaf traits and ecosystem functioning in Inner Mongolia grasslands: scaling from species to community
grazing on leaf traits ecosystem functioning Inner Mongolia grasslands scaling from species to community
2015/2/4
Understanding the mechanistic links between environmental drivers, human disturbance, plant functional traits, and ecosystem properties is a fundamental aspect of biodiversity-ecosystem functioning re...
Grazing resistance allows bloom formation and may explain invasion success of Gonyostomum semen
Grazing resistance bloom formation may explain invasion success Gonyostomum semen
2014/4/3
The nuisance alga Gonyostomum semen (Raphidophyceae) has expanded in the Nordic countries during the last decades and can dominate lake phytoplankton communities almost completely. A possible explanat...
Maternal Effects of Japanese Shorthorn Cows on the Growth of Embryo-transferred Japanese Black Calves in a Cow-calf Grazing System
Japanese Shorthorn Japanese Black Cattle Embryo Transfer Cow-calf Grazing
2016/5/12
The growth performance of embryo-transferred Japanese Black calves that were born from, and suckled by, Japanese Shorthorn cows in a cow-calf grazing system (BS-group, n = 5) was compared to that of J...

Does warming enhance the effect of microzooplankton grazing on marine phytoplankton in the ocean?
warming enhance the effect of microzooplankton grazing marine phytoplankton in the ocean
2014/4/2
We evaluated a hypothesis derived from the metabolic theory of ecology (MTE) that the ratio of microzooplankton herbivory (m) to phytoplankton growth (m) will arise in a warming ocean because of the d...
Mass Loss, Destruction and Detection of Sun-grazing and -impacting Cometary Nuclei
comet sun impact sun-grazing radiation collisions
2011/9/30
Incoming sun-grazing comets almost never re-emerge, but no final destruction event has ever been observed, nor sun-impactor destruction theory developed. We seek analytic models of comet nucleus destr...
Asymptotic of grazing collisions and particle approximation for the Kac equation without cutoff
Kinetic Theory Kac equation grazing collisions Particle systems
2011/7/26
Abstract: The subject of this article is the Kac equation without cutoff. We first show that in the asymptotic of grazing collisions, the Kac equation can be approximated by a Fokker-Planck equation. ...
Local genetic adaptation to grazing pressure of the green algaDesmodesmus armatusin a strongly connected pond system
Local genetic adaptation grazing pressure the green alga Desmo desmus armatusin strongly connected pond system
2014/4/17
Dispersal potentially homogenizes genetic variation among populationsand thus may prevent local genetic adaptation. If selection gradients are strong and the selection responseefficient, however, loca...
Relationships between phytoplankton growth and cell size in surface oceans: Interactive effects of temperature, nutrients, and grazing
phytoplankton growth cell size in surface oceans Interactive effects temperature nutrients grazing
2014/4/17
We compile two data sets from14C uptake and dilution experiments conducted in surface waters of the global ocean to investigate the relationship between phytoplankton mass-specific growth rate and cel...

Intense benthic grazing of phytoplankton coral reef
2014/4/18
Grazing on phytoplankton by a section of the fringing coral reef in Eilat, the Gulf of Aqaba, Red Sea, was studied using the control-volume approach, a direct, nonintrusive technique common in enginee...
