Locomotor performance can influence the ecological and evolutionary success of a species. For fish, favorable outcomes of predator-prey encounters are often presumably due to robust acceleration ability. Although escape-response or “fast-start” studies utilizing high-speed cinematography are prevalent, little is known about the contribution of relative acceleration performance to ecological or ...

Diel studies of an Emiliania huxleyi bloom within a mesocosm revealed a highly dynamic associated viral community, changing on small times scales of hours.

A minimum mathematical model of the marine pelagic microbial food web has previously shown to be able to reproduce central aspects of observed system response to different bottom-up manipulations in a mesocosm experiment Microbial Ecosystem Dynamics (MEDEA) in Danish waters. In this study, we apply this model to two mesocosm experiments (Polar Aquatic Microbial Ecology (PAME)-I and PAME-II) con...

This study creates both virtual and physical, closed, aquatic mesocosms. Each mesocosm consisted of a 10 gal aquarium with an unspecified proportion of water and air. The contents of the aquarium included several crayfish, dechlorinated water, gravel, and submerged aquatic and terrestrial plants. The mesocosm was self−sustaining, airtight, watertight, and food tight. By reaching equilibrium bet...

Knowledge of nutrient pathways and their resulting ecological interactions can alleviate numerous environmental problems associated with nutrient increases in both natural and managed systems. Although not unique, coastal systems are particularly prone to complex ecological interactions resulting from nutrient inputs from both the land and sea. Nutrient inputs to coastal systems often spur ulvo...

Mesocosm experiments in an optically transparent lake allow the manipulation of both dissolved organic carbon (DOC) and incident ultraviolet radiation (UVR) in order to study mercury reduction and emission processes. In the absence of UVR and the presence of visible light, mercury emission is very low (approximately0.3 ng/m2/h). When UVR is permitted in the mesocosm chambers, mercury emission i...

There is debate about whether results from mesocosm studies should be extrapolated to natural ecosystems. Critics argue that the abiotic and biotic characteristics of mesocosms do not represent the in situ conditions of the habitats in which they are designed to mimic. We addressed this idea by deploying mesocosms in two lakes of varying trophic status (mesotrophic and eutrophic). Water chemist...

1. Experiments in ecology occur in the laboratory, mesocosm, or field. The choice of venue can influence the outcome and may be associated with trade-offs involving realism and precision. 2. We evaluated these trade-offs in an experiment measuring effects of venue on larval traits of Rana temporaria tadpoles. The design included lab, mesocosm, and field venues, crossed with two treatments (pres...
