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 کاملPlanktonic copepods reacting selectively to hydrodynamic disturbances.
In the water column, planktonic copepods encounter small-scale hydrodynamic disturbances generated by fellow zooplankters. Our question is whether or not the copepods can distinguish between hydrodynamic disturbances created by predators, prey, conspecifics and/or mates. We used a Schlieren optical system with a density gradient in the water volume and filmed at 48 frames per second to record t...
متن کاملشناسایی و تخمین جمعیت پاروپایان پلانکتونیک (Planktonic Copepods) خورموسی
این تحقیق به منظور شناسایی و تخمین تراکم پاروپایان پلانکتونیک خورموسی از آذرماه 1376 لغایت بهمن ماه 1377 در چهار ایستگاه انجام پذیرفت. در این پروژه از زمان شروع یعنی آذر 1376 لغایت شهریور 1377 نمونه برداری بصورت ماهانه انجام شد. پس از این مدت دو تکرار در ماههای آذر و بهمن 1377 اجرا گردید. نمونه برداری از سطح و ستون آب (از عمق 20 متری تا سطح) انجام شد. در کل نمونه برداری ها مجموعاً 16 جنس از پارو...
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 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...
