Evolution of bioluminescence in marine planktonic copepods.
Copepods are the dominant taxa in zooplankton communities of the ocean worldwide. Although bioluminescence of certain copepods has been known for more than a 100 years, there is very limited information about the structure and evolutionary history of copepod luciferase genes. Here, we report the cDNA sequences of 11 copepod luciferases isolated from the superfamily Augaptiloidea in the order Ca...
متن کاملMortality of marine planktonic copepods: global rates and patterns
Using life history theory we make predictions of mortality rates in marine epi-pelagic copepods from field estimates of adult fecundity, development times and adult sex ratios. Predicted mortality increases with temperature in both broadcast and sac spawning copepods, and declines with body weight in broadcast spawners, while mortality in sac spawners is invariant with body size. Although the m...
متن کاملEffects of temperature and oxygen tension on oxygen consumption rates of nauplii of different Artemia strains
Effects of temperature and Po2 have been examined on rates of oxygen consumption ( a o 2 ) of nauplii of 5 difterents Artemia strains acclimated to 30 %OS. In 4 strains there were no significant differences in relations between Pho2 and temperature over the temperature ranges offered (15 to 35 "C). In 1 strain (Delta del Ebro), the temperature effect on h?02 was much lower than in the other str...
متن کاملMandibular gnathobases of marine planktonic copepods – feeding tools with complex micro- and nanoscale composite architectures
Copepods are dominant members of the marine zooplankton. Their diets often comprise large proportions of diatom taxa whose silicified frustules are mechanically stable and offer protection against grazers. Despite of this protection, many copepod species are able to efficiently break even the most stable frustule types. This ability requires specific feeding tools with mechanically adapted arch...
متن کاملIngestion and sublethal effects of physically and chemically dispersed crude oil on marine planktonic copepods
Planktonic copepods play a key function in marine ecosystems, however, little is known about the effects of dispersants and chemically dispersed crude oil on these important planktonic organisms. We examined the potential for the copepods Acartia tonsa, Temora turbinata and Parvocalanus crassirostris to ingest crude oil droplets and determined the acute toxicity of the dispersant Corexit(®) 950...
