Mesocosms

Ecosystems represent interactions between biological elements (ie communities) and nonbiological elements (ie habitats).

They are basically independent and can keep themselves for a long time

Energy availability - Light from the sun provides initial energy to almost every community

The availability of nutrients - the drought tolerance resolver will ensure continuous circulation of inorganic nutrients in the environment

Waste recycling - Specific bacteria can detoxify harmful waste byproducts (eg denitrifying bacteria such as nitrosomonas)

Methocosm is a closed environment that allows you to observe a small part of the natural environment under controlled conditions.

Glass containers are small transparent containers (such as glass or plastic) in which the selected plants (or animals) are preserved and observed.

Follow the steps below to create a glass container using a glass bottle or plastic bottle with a lid.

Add pebble, gravel or sand layer - this layer is used for drainage (small ships require thinner rock layers)

Apply a thin layer of peat moss (or use an organic coffee filter) to form a barrier between the lower layer and the soil

Ideally, select plants that grow slowly and prosper in high humidity environments (eg most ferns, mosses etc.)

Please thoroughly check plants for signs of diseases and insects before introducing glass containers

Place the glass container in a place where there is no temperature fluctuation (avoid direct sunlight).

At first do not sprinkle plants too much - Once the correct humidity is decided, the glass container can last for several months without watering

Occasionally pruning may be necessary - but as soil nutrient levels go down, plant growth should slow down

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 investigated the influence factors of the DOC / CDOM relation through a new medium scale experiment and sample sampling of 6 years. Please check the DOC product and DOC / CDOM covariant. The mesocosm experiment was designed as a control condition to analyze the influence of vegetation and temperature on the DOC / CDOM relation, respectively. Seasonal DOC / CDOM changes in different land cover catchments were also assessed. Our results show that the general change in DOC / CDOM is influenced by land cover type and temperature. If CDOM is used as a surrogate for DOC concentration, you should pay attention to these environmental factors.
