متن کاملThe stable isotopic composition of Daphnia ephippia reflects changes in δC and δO values of food and water
The stable isotopic composition of fossil resting eggs (ephippia) of Daphnia spp. is being used to reconstruct past environmental conditions in lake ecosystems. However, the underlying assumption that the stable isotopic composition of the ephippia reflects the stable isotopic composition of the parent Daphnia, of their diet and of the environmental water have yet to be confirmed in a controlle...
متن کاملVariability in blood alcohol concentrations. Implications for estimating individual results.
In a carefully controlled drinking situation there was great individual variation in peak blood alcohol concentrations (BACS) for given doses of alcohol. Alcohol nomograms and tables based on average results from such studies could be misleading since they could frequently result in serious underestimates or overestimates of peak BACS.
متن کاملGenetic versus environmental influence on pigment variation in the ephippia of Daphnia pulicaria
1. The dormant eggs of Daphnia (Crustacea: cladocera) are encased in a protective, chitonous casing known as an ephippium. Ephippia are pigmented with melanin, and the degree of pigmentation ranges from transparent to opaque. Variation in pigmentation exists within and across populations and species, raising questions about the factors that influence the natural distribution of pigmentation. 2....
متن کاملContext-dependent individual behavioral consistency in Daphnia
The understanding of consistent individual differences in behavior, often termed “personality,” for adapting and coping with threats and novel environmental conditions has advanced considerably during the last decade. However, advancements are almost exclusively associated with higher-order animals, whereas studies focusing on smaller aquatic organisms are still rare. Here, we show individual d...
