Study explores ancient ecosystem response to a “big five” mass extinction, calls for modern food web research
ancient ecosystem big five mass extinction modern food web research
2015/10/13
As the planet faces the dawn of a sixth mass extinction, scientists are searching for clues about the uncertain road ahead by exploring how ancient ecosystems collapsed and bounced back from traumatic...
Modeling Food Web Interactions in Benthic Deep-Sea Ecosystems
Deep-Sea Ecosystems Web Interactions
2015/7/3
Deep-sea benthic systems are notoriously difficult to sample. Even more than for other benthic systems, many
flows among biological groups cannot be directly measured, and data sets remain incomplete...
Local climatic changes impact algae living inside the sea ice, which may drastically affect near shore Arctic marine food webs
Scientists traveled to a town near the top of the world to study a creat...
A size-structured food-web model for the global ocean
A size-structured food-web model the global ocean
2014/4/2
We present a model of diverse phytoplankton and zooplankton populations embedded in a global ocean circulation model. Physiological and ecological traits of the organisms are constrained by relationsh...
Terrestrial support of zebra mussels and the Hudson River food web: A multi-isotope, Bayesian analysis
Terrestrial support of zebra mussels Hudson River food web A multi-isotope Bayesian analysis
2014/4/2
The Hudson River is a strongly heterotrophic system in which the invasive zebra mussel (Dreissena polymorpha) comprises >90% of total metazoan biomass. Using a Bayesian mixing model, with isotope rati...
Getting the ‘‘right’’ parameter values for models of the pelagic microbial food web
Getting the rightp arameter values models pelagic microbial food web
2014/4/2
The microbial part of the pelagic food web is believed to be a highly dynamic and tightly coupled network in which system behavior emerges from organism properties and interactions. A central goal in ...
Revealing organic carbon sources fueling a coral reef food web in the Gulf of Mexico using stable isotopes and fatty acids
Revealing organic carbon sources coral reef food web Gulf of Mexico stable isotopes fatty acids
2014/4/2
Carbon and nitrogen stable isotopes and fatty acids (FAs) revealed primary producer organic carbon sources that fuel a coral reef food web with river influence. A stable isotope mixing model was used ...
Food web consequences of size-based predation and vertical migration of an invertebrate predator (Leptodora kindtii)
size-based predation an invertebrate predator
2014/4/2
In an intensive study of the vertical and horizontal distribution of zooplankton in a eutrophic lake (Katepwa
Lake), we found that only adult Leptodora kindtii (. 5 mm in body size) exhibited diel ve...
The Effect of Differentiation of Prey Community on Stable Coexistence in a Three-Species Food--Web Model
Intraguild predation Immobilization Alternative resource Multiple resource traits Stable coexistence
2012/4/28
Food webs with intraguild predation (IGP) are widespread in natural habitats. Their adaptation and resilience behaviour is principal for understanding restructuring of ecological communities. In spite...

Dissolved carbon dioxide concentration controls baseline stable carbon isotope signatures of a lake food web
Dissolved carbon dioxide concentration controls baseline stable carbon isotope signatures a lake food web
2014/4/4
Temporal variation in the baseline stable carbon isotope (δ13C) value of a well-studied, productive lake was examined over a 26-yr period using archived samples of the herbivorous zooplankter Daphnia ...

2014/4/8
This study investigates the effect of filtrates from an allelopathic dinoflagellate, Alexandrium tamarense, on
four microbial food webs that have been manipulated experimentally from natural seawater...
Effects of experimental warming and increased ultraviolet B radiation on the Mediterranean plankton food web
experimental warming increased ultraviolet
2014/4/4
The responses of the plankton food web to increases in temperature and ultraviolet B radiation (UVBR, 280–
320 nm) were experimentally investigated at a coastal Mediterranean site during spring. Eigh...
