Bacterial metabolism and growth efficiency in lakes: The importance of phosphorus availability
Bacterial metabolism growth effi ciency
2014/5/14
We investigated bacterial responses to variations in dissolved organic carbon (DOC) and nutrient availability by
a comparative analysis of bacterial metabolism in lakes ranging from oligotrophic to e...
Predation efficiency in visual and tactile zooplanktivores
tactile zooplanktivores Predation effi ciency
2014/5/14
Gelatinous zooplanktivores (medusae, siphonophores, and ctenophores) and visual zooplanktivores (fish) interact
through competition, predation, and commensalism. In the search for key factors g...
D-H fractionation in Sporomusa ORIGINAL ARTICLE Blackwell Publishing, Ltd. Hydrogen isotope fractionation during H2 /CO2 acetogenesis: hydrogen utilization efficiency and the origin of lipid-bound hydrogen
ORIGINAL ARTICLE D-H fractionation
2014/4/8
Hydrogen metabolism was studied in the anaerobic bacterium, Sporomusa sp. strain DMG 58, by measuring
natural abundance levels of deuterium in H2
, H2O, and individual fatty acids during acetogenic ...
Effects of ultraviolet-B radiation and vertical mixing on nitrogen uptake by a natural planktonic community shifting from nitrate to silicic acid deficiency
ltraviolet-B radiation vertical mixing
2014/5/20
We investigated the combined effects of mixing regimes and ultraviolet-B radiation (UVBR: 280–320 nm) on
the uptake of nitrate, ammonium, and urea by an estuarine phytoplankton community during a 10-...
Effects of dietary phosphorus deficiency on the abundance, phosphorus balance, and growth of Daphnia cucullata in three hypereutrophic Dutch lakes
dietary phosphorus defi ciency abundance phosphorus balance
2014/5/30
We studied population dynamics, phosphorus balance, and individual growth to evaluate limitation of Daphnia
cucullata by dietary phosphorus (P) in three interconnected, hypereutrophic Dutch lakes. Co...
Orientation in complex chemical landscapes: Spatial arrangement of chemical sources influences crayfish food-finding efficiency in artificial streams
complex chemical landscapes chemical sources infl uences
2014/5/30
Fluid dynamics has been shown to alter ecologically important behaviors of aquatic organisms orienting to distant
chemical sources. Because the fluid dynamics and chemical plumes change across ...
