Temperature gradients, not food resource gradients, affect growth rate of migrating Daphnia mendotae in Lake Michigan
Index words: Laurentian Great Lakes Vertical migration Zooplankton production Deep chlorophyll maxima Non-consumptive effects Zooplankton production plays a critical role in the Great Lakes ecosystem, and vertical migration, which is exhibited by many zooplankton species, could affect production. We examined the effects of water temperature and food resource gradients on the growth rate of zoop...
متن کاملBehavioral response of Lake Michigan Daphnia mendotae to Mysis relicta
We performed laboratory experiments to determine if Mysis relicta induce changes in the behavior of Daphnia mendotae collected from Lake Michigan. Laboratory results indicate that Daphnia perceived Mysis kairomones and responded by changing their vertical position in cylinders. Experiments using different resource levels, and two procedures to examine the potential effects of the chemical cues ...
متن کاملBacteria dispersal by hitchhiking on zooplankton.
Microorganisms and zooplankton are both important components of aquatic food webs. Although both inhabit the same environment, they are often regarded as separate functional units that are indirectly connected through nutrient cycling and trophic cascade. However, research on pathogenic and nonpathogenic bacteria has shown that direct association with zooplankton has significant influences on t...
متن کاملLarge nonlethal effects of an invasive invertebrate predator on zooplankton population growth rate.
We conducted a study to determine the contribution of lethal and nonlethal effects to a predator's net effect on a prey's population growth rate in a natural setting. We focused on the effects of an invasive invertebrate predator, Bythotrephes longimanus, on zooplankton prey populations in Lakes Michigan and Erie. Field data taken at multiple dates and locations in both systems indicated that t...
متن کاملPseudo-diel vertical migration in zooplankton: a whole-lake N tracer experiment
Diel vertical migration (DVM) of zooplankton is commonly considered an adaptation for feeding in food-rich and warm surface waters at night and avoiding visual predators during the day. However, the critical assessment of migration patterns frequently suggests that: (i) zooplankton may leave deeper waters with rich, deepchlorophyll layers and move into the epilimnion where food resources are lo...
