Trophic Relationships and Diet of Consumers in Temperate Kelp Forest and Coral Reef Ecosystems
Temperate Kelp Forest Coral Reef Ecosystems
2015/7/16
We explored the use of stable nitrogen (N) isotope analysis to assess trophic position of consumers in two marine ecosystems: the kelp forests of southern California and a coral atoll in the tropical ...
Nutrient enrichment differentially affects body sizes of primary consumers and predators in a detritus-based stream
Nutrient enrichment differentially affects body sizes predators
2014/4/17
We assessed how a 5-yr nutrient enrichment affected the responses of different size classes of primary
consumers and predators in a detritus-based headwater stream. We hypothesized that alterations i...
Growth rate versus biomass accumulation: Different roles of food quality and quantity for consumers
Growth rate versus biomass accumulation food quality
2014/4/22
Population growth and biomass accumulation of Daphnia magna was studied in a two-stage continuousculture system with light- and phosphorus-limited green algae (Selenastrum capricornutum) as food sourc...
food and drug administration Re-Emphasizes Warnings to Consumers on Risks of Pet Turtles
bacteria Salmonella
2007/4/11
April 6, 2007,The Food and Drug Administration (FDA) is urgently reminding the public that contact with baby turtles can pose a serious health risk to infants, small children, and adults with impaired...
food and drug administration and CDC Remind Consumers of the Dangers of Drinking Raw Milk
raw milk bacteria Brucella
2007/3/9
March 1, 2007，The U.S. Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) are reminding consumers of the dangers of drinking milk that has not been pasteurized...
Stable isotopes in subtidal food webs: Have enriched carbon ratios in benthic consumers been misinterpreted?
subtidal food webs Have enriched carbon ratios
2014/5/5
We examined the hypothesis that the d13
C of benthic consumers is depleted in offshore, deeper waters where
kelp and benthic microalgae are absent by conducting three analyses: (1) we analyzed d13
...
The effects of cultural eutrophication on the coupling between pelagic primary producers and benthic consumers
The effects of cultural eutrophication coupling pelagic primary producers benthic consumers
2014/5/13
We investigated the effects of cultural eutrophication on the coupling between pelagic primary producers and benthic consumers in Lake Tahoe. Spatial and temporal changes in zoobenthos energetics were...
Littoral energy mobilization dominates energy supply for top consumers in subarctic lakes
Littoral energy mobilization energy supply top consumers subarctic lakes
2014/5/9
We used stable carbon (δ13C) and nitrogen (δ15N) isotopes to assess the energy sources supporting the top consumer (Arctic char, Salvelinus alpinus) in nine subarctic lakes in northern Sweden. The δ13...
Primary consumers and particulate organic matter: Isotopic evidence of strong selectivity in the estuarine transition zone
Primary consumers particulate organic matter
2014/5/19
The freshwater–saltwater transition zones of upper estuaries often contain high concentrations of particulate
organic matter (POM) that could potentially support their productive food webs. Our objec...
Do brominated natural products defend marine worms from consumers? Some do, most don’t
brominated natural products marine worms consumers
2014/5/14
Worms and other marine invertebrates living in soft sediments commonly produce brominated natural products that have been hypothesized to function as defenses against consumers, but this hypothesis ha...
Palatability of marine macro-holoplankton: Nematocysts, nutritional quality, and chemistry as defenses against consumers
marine macro-holoplankton Nematocysts nutritional quality chemistry defenses against consumers
2014/5/26
Chemical defenses against consumers have been hypothesized to be common among marine macro-holoplankton, but few studies have assessed macro-holoplankton susceptibility to predators or the traits affe...
