Vitamin B-12 knockoff version create complex market marine vitamins
2017/2/16
The New Year is a busy time for pharmacies and peddlers of all health-related products. In the oceans, marine organisms rely on nutrients, too, but the source of their vitamins is sometimes mysterious...
The Global,Complex Phenomena of Harmful Algal Blooms
Global Complex Phenomena Harmful Algal Blooms
2015/7/27
Marine and fresh waters team with life, much of it microscopic, and most of it harmless; in fact, it is this microscopic life on which all aquatic life ultimately depends for food. Microscopic algae a...
Mitochondrial sequence variation suggests extensive cryptic diversity within the Western Palearctic Daphnia longispina complex
Mitochondrial sequence variation extensive cryptic diversity the Western Palearctic Daphnia longispina complex

To investigate the importance of symbiont-derived nutrition to host sponges, we coupled manipulative shading experiments with stable isotope analyses of isolated symbiont and host cell fractions. Expe...
Biochemical food quality effects on a Daphnia hybrid complex
Biochemical food quality a Daphnia hybrid complex
2014/4/21
Correlative field studies have shown that the food quality of natural seston for Daphnia is highly correlated with the content of eicosapentaenoic acid (EPA), indicating that the growth of Daphnia in ...
Population dynamics of a freshwater calanoid copepod: Complex responses to changes in trophic status and climate variability
Population dynamics a freshwater calanoid copepod Complex responses changes in trophic status climate variability
2014/4/21
The long-term dynamics of the calanoid copepod Eudiaptomus gracilis were analyzed in Lake Constance, a deep lake that has been influenced strongly by changes in trophic status and climate variability ...
Agent-based modeling of the complex life cycle of a cyanobacterium (Anabaena)ina shallow reservoir
Agent-based modeling complex life cycle cyanobacterium a shallow reservoir
2014/4/18
The cyanobacteriumAnabaena flos-aquaeand many other phytoplankton species have a complex life cycle that includes a resting stage (akinete). We present a new agent-based (also known as individual-base...
Complex interactions between the zebra mussel, Dreissena polymorpha, and the harmful phytoplankter, Microcystis aeruginosa
zebra mussel Dreissena polymorpha harmful phytoplankton Microcystis aeruginosa
2014/5/9
We report a reversal in the sign of the herbivore-phytoplankton interaction between the zebra mussel (Dreissena polymorpha) and Microcystis aeruginosa, a harmful planktonic cyanobacterium. A pair of l...
Genetic diversity in the Gammarus pecos species complex: Implications for conservation and regional biogeography in the Chihuahuan Desert
Genetic diversity Gammarus pecos species complex conservation and regional biogeography Chihuahuan Desert
2014/5/14
We used allozyme electrophoresis to quantify genetic variation in nine populations of the Gammarus pecos species complex endemic to spring systems of the northern Chihuahuan Desert. There was signific...
Do we need complex mechanistic photoacclimation models for phytoplankton?
complex mechanistic photoacclimation models phytoplankton
2014/5/22
The outputs of simple models relating phytoplankton growth and chlorophyll a (Chl a) to irradiance and nutrient (nitrogen [N] and/or iron [Fe]) availability are compared with those of complex mechanis...
In lakes of small to medium size, the characteristic frequencies of free oscillations of the water surface (seiches) depend only on the basin geometry. In irregularly shaped basins, such as dendritic ...
