SUSPENSION-FEEDING IN MARINE SPONGES HALICHONDRIA-PANICEA AND HALICLONA-URCEOLUS - EFFECTS OF TEMPERATURE ON FILTRATION-RATE AND ENERGY-COST OF PUMPING
Filtration rate (measured as clearance of algal cells) was measured at different temperatures in the sponge Halichondna panicea. An increase in water temperature from 6 to 12 "C caused the meanExpand
Prey size selection, grazing and growth response of the small heterotrophic dinoflagellate Gymnodinium sp. and the ciliate Balanion comatum--a comparative study
Prey selectivity, growth and feeding responses were studied in the cillate Balanion comaturn (17 pm) and the heterotroph~c dinoflagellate Gjmnodinium sp. (7 pm). Almost identical prey size spectraExpand
Phaeocystis globosa (Prymnesiophyceae) and the planktonic food web: Feeding, growth, and trophic interactions among grazers
TLDR
The study showed that the trophic efficiency of a system dominated by P. globosa is dependent on the complex food-chain structures within the planktonic food web. Expand
Effect of heterotrophic versus autotrophic food on feeding and reproduction of the calanoid copepod Acartia tonsa : relationship with prey fatty acid composition
TLDR
The data do not show that ciliates and heterotrophic dinoflagellates are nutritionally superior prey for marine copepods, contrary to general expectations, and egg viability was correlated with ingestion of certain prey essential fatty acids. Expand
Escape response of planktonic protists to fluid mechanical signals
TLDR
Jump behaviour may also enhance susceptibility to some predators, explaining the different predator avoidance strategies (jumping or not) that have evolved in plank- tonic protists. Expand
Recovery of Danish Coastal Ecosystems After Reductions in Nutrient Loading: A Holistic Ecosystem Approach
In the 1980s, Danish coastal waters suffered from eutrophication and several nutrient management plans have been implemented during the years to improve ecological status. This study aims at giving aExpand
Effects of protozoan grazing on colony formation in Phaeocystis globosa (Prymnesiophyceae) and the potential costs and benefits
TLDR
Colony formation by Phaeocystis globosa was enhanced in terms of colony size when solitary P. globosa cells were grazed by the heterotrophic dinoflagellates Noctiluca scintillans and Gyrodinium dominans and the costs of colony formation must be sought elsewhere. Expand
Agricultural Robotic Platform with Four Wheel Steering for Weed Detection
Abstract A robotic platform for mapping of weed populations in fields was used to demonstrate intelligent concepts for autonomous vehicles in agriculture which may eventually result in a newExpand
Circadian cycles in growth and feeding rates of heterotrophic protist plankton
TLDR
It is suggested that protists use a time-integrated light threshold rather than an instantaneous irradiance to maintain the circadian cell cycle, which allows them to avoid temporary arrests in growth and feeding when they are mixed over depth across the 3.1 × 10−4 µmol photons m−2 s−1 irradiance threshold. Expand
Mechanisms and feasibility of prey capture in ambush-feeding zooplankton
TLDR
It is argued that power requirements for acceleration and the hydrodynamic constraints restrict the strategy to larger (> 0.25 mm), muscular forms with well-developed prey perception capabilities, and the smallest of the examined species is close to this size limit. Expand
