WHAT IS A MESOCOSM?

Aquatic biota, or experimental water seal. It is designed to provide limited waters close to natural conditions.

This Mesozoic provides a powerful tool for association between in situ but usually only in one field for research in related fields and on the other hand is away from the narrow range of natural laboratory experiments I will. There are one or more species. Therefore, compared to laboratory methods, biological research in China takes into consideration the relevant aspects of the "real world" such as indirect impact, biological compensation and recovery, ecological resilience, It has the advantage of bringing community closer to natural conditions.

Therefore, mesocosm law is generally considered to be the experimental ecosystem closest to the real world without losing reliable reference conditions and the advantages of replication. The responses obtained from mesodermal studies can be used for parameterization in ecosystem and biogeochemical models by integrating the effects of multiple direct and indirect species on the food net.

Mesocosms is the perfect tool to study the impact of ecosystems on conditions related to the field. Medium scale global research design is based on fully answered questions. Apply medium-sized organisms to freshwater and marine environments to examine substances (such as pesticides, polluted sediments, complex sewage) and other disturbances (such as turbidity, eutrophication, temperature / cooling water) to the ecosystem can do. In addition, mesocosm provides an excellent tool for studying the fate of chemical substances.

Over the past two decades, we have gained extensive experience in all types of medium sized world. In addition to the standard stagnant pond, we also use a trough system to study the complex sewage, the tidal ocean system, and the long-term impact of the midsize world. For problems related only to the deep seabed raw system plankton community, we use the plankton enclosure. Most mesocosm types can be used to study marine and freshwater environments

In this paper, we use a fairly robust ecosystem model known in simulated oceanographic experiments (Watts and Bigg, 2001) and applied it to two medium sized world data sets from the same experiment station in the Norway fjord I will. The main plankton species tested in the open ocean were the same as E. huxleyi, a dominant species, intermediate experiment. By adopting a successful, relatively simple marine ecosystem model and applying it to the midsize world, you will have the opportunity to evaluate the applicability of mid-sized experiments to the marine environment.

This research shows the positive and negative aspects of biological experiments as a model for opening marine ecosystems. The positive result is that the model which showed the Lagrangian movement to the flowers of E. huxleyi in the open ocean so far (Watts and Bigg, 2001) can describe the primary flow behavior of similar flowers in relatively small organisms . . The interesting thing is that it is done using the same rate parameter as the ocean. However, this study also highlighted several drawbacks. Even relatively simple ocean models, as used here, have the opportunity to make the simulation successful.
