[ Focus on Chemical Machinery and Equipment Network ] China is one of the countries with rich biodiversity
.
According to statistics from the State Forestry and Grassland Administration, China currently has 11,800 protected areas of various types, accounting for 18% of the land area and 4.
1% of the territorial waters
.
Among the wild animals distributed in nature, there are about 7,300 species of vertebrates, including 564 species of beasts, 416 species of amphibians, 1,445 species of birds, 463 species of reptiles, and the rest are fish; about 130,000 species of insects have been named; higher plants There are more than 30,000 species, including more than 17,000 species of endemic plants
.
In the face of abundant species, real-time biological monitoring is very necessary
.
Biodiversity monitoring is the repeated cataloging of biodiversity on a time scale to determine its changes
.
It not only understands the situation of biodiversity and the scope of ecological zoning, but also provides effective data on issues such as protecting biodiversity and evaluating environmental impacts

Recently, researcher Yu Weili from the Kunming Institute of Zoology, Chinese Academy of Sciences and his team improved the high-quality barcode technology for rapid monitoring of biodiversity.
The result is named "Biodiversity Soup II: High-throughput barcode process with lower error rate" Published in the international journal "Ecology and Evolutionary Methods"

High-throughput sequencing technology monitoring to obtain large amounts of biological data
"Biodiversity soup" is a novel biodiversity monitoring method with high-throughput sequencing technology, which can analyze a large number of mixed biological samples at the same time to obtain ground biodiversity data
.
.
Every organism contains DNA, and any DNA fragments can be used for biological species identification, thereby realizing biological monitoring

With the help of "Biodiversity Soup", researchers explored the biodiversity of moths at different altitudes in the Yunnan Nature Reserve.
The results showed that the community composition of moths varies with altitude and sampling level
.
Not only that, the "biodiversity soup" can also analyze the influence of fungal diversity on the decomposition of deadwood: the more fungi species, the lower the carbon dioxide release rate of deadwood, and the slower the decay of deadwood

Reduce high data costs and promote the development of multiple disciplines
At present, biodiversity monitoring includes the monitoring of diversity within communities, diversity indices between communities, and similar habitat indices in different places
.
The monitoring methods are mostly manual, instrument, and genetic technology monitoring
.
For example, using infrared trigger cameras to clearly monitor beasts and ground-moving birds, recorders automatically collect bird calls, and use soundscape analysis to identify biological species and evaluate diversity
.
Another example is that molecular-omics technology is not widely used in biodiversity monitoring
.
Metagenomics method is a common method for soil microorganism identification and monitoring
.
The morphology of soil animals is difficult to identify and takes a long time.
Combining conventional morphological identification with molecular technology will play a certain role in promoting the diversity of soil animals

These traditional monitoring methods consume a lot of labor, equipment and other project costs
.
Moreover, due to the large scale of sampling and classification, research is limited to relatively small areas that are more targeted and difficult to replicate
.
Therefore, conservation scholars and environmental managers often can only use limited data to make decisions

Compared with traditional monitoring, the "biodiversity soup" technology, with its characteristics of fast, efficient, and wide monitoring range, realizes large-scale replication and inspection through high-throughput technology, greatly reduces monitoring costs, and can analyze a large number of mixtures at the same time Samples, obtain accurate biodiversity data, provide high-speed and efficient third-party inspection data, and strengthen monitoring of the environmental change index and the status of endangered species
.
.
The "biodiversity soup" promotes the development of biological monitoring from morphology, cytology, physiology and biochemistry to molecules, and profoundly reveals the heredity and variation of genetic material
.
This kind of technology has gradually been incorporated into their daily monitoring work by the nature protection management departments of many countries, improving the experimental design and bioinformatics analysis process, reducing the error rate and increasing the calculation speed
.
In addition, the “biodiversity soup” not only draws attention to the changes in biodiversity itself, but also extends people’s attention to factors that affect biodiversity, such as climate change, land use, environmental pollution, etc.
, and contributes to related disciplines such as agronomy, Forestry, fisheries, soil science, etc.

Build a multi-dimensional monitoring system to solve two major problems
At present, biodiversity survey, assessment and monitoring are the main means to obtain biodiversity data, and it is also a prerequisite for carrying out biodiversity protection
.
However, it is still a difficult problem to obtain a large amount of species information
