Diatoms contribute nearly half of the marine primary production. These microalgae differ from other phytoplankton groups in having a silicified cell wall, which is the strongest known biological material relative to its density. While it has been suggested that a siliceous wall may have evolved as a mechanical protection against grazing...
Our traditional view of the interactions between marine organisms is conceptualized as food webs where species interact with one another mainly via direct consumption. However, non-consumptive interactions, such as behaviorally mediated indirect interactions (BMIIs), can influence marine ecosystems as much as consumptive effects. Here...
Ectotherms often grow to a smaller adult body size when reared in warmer conditions. Typically, this is because development rate increases faster than growth rate with warming, causing individuals to mature earlier but at a smaller size. Yet, few studies have examined how these temperature-size responses are established over the entire...
What zooplankton foraging strategy is more efficient in terms of volume of water cleared? What mechanism determines clearance efficiency of zooplankton foraging strategies? Why may different zooplankton foraging strategies coexist in plankton food webs?
After oil spills and dispersant applications, the formation of red tides or harmful algal blooms (HABs) has been observed, but the link between both phenomena was unknown until now.
Can sexual dimorphism lead to differences in starvation tolerance between copepod genders? Can mating activities reduce starvation tolerance in planktonic copepods?
Can differences in behavior between genders lead to reduced male feeding rates?
Differences in motile behavior related to feeding and mate finding lead up to almost an order of magnitude difference in mortality risk?
What is the cost in terms of predation risk of different feeding behaviours in zooplankton? What feeding strategies are more risky? Are copepod males more susceptible to predation than females?
