Climate change will seriously affect bird species

In the recently released "Bird Red List of 2022", many bird species have been evaluated. Chinese biological diversity protection and Green Development Foundation (referred to as the China Green Fair, Green Club) as a partner of the United Nations Convention on Wild Animal Migration Species (CMS), an observer agency of the "CMS Central Asian Qianfei District initiative", Continue to pay attention to the protection of bird biological diversity and the latest developments. Recently, the China Greenford Bird Watching Working Group learned from an internationally renowned journal about a study on climate change affecting bird species. This article is compiled as follows, for the reference of interesting readers.

Biological scientists from Durham University and Germany's Senkeberg Biological Diversity and Climate Research Center (SenCKENBERG BIODIVERSITY and Climate Research Center) predict in their latest research that the scope of the scope of activities of birds due Change, by 2080, the area where birds around the world will change. This study was published in the "Proceedings of the Royal Society B".

In order to predict bird habitats in 2080, the team of scientists associates the past bird distribution with climate data, and then applies these relationships to two future climatic scenes based on low and moderate greenhouse gas emissions to predict species distribution The change.

The team not only focuses on changes in the number of species in the area, but also pays attention to the types of species that will appear in the future. In order to summarize the changes in species type, they also calculated a data called system development diversity, which predicts how many types of birds will appear. For example, a community with a large number of close -related species, such as the ringing poultry eating insects, its system development scores will include more than more communities with more long -distance related species. Or seagulls.

They investigated the possible changes in bird communities around the world in the future, and found that climate change will not only affect the number of species, but also have a profound impact on system development diversity and community composition.

The system development diversity of bird species caused by climate change may be increasing, including European-eating Birds (a kind of insect bird), black-winged stilts (Black-Winged Stilts) and Spoonbills. Occasionally, it is occasionally breeding in the UK, but before that, they usually breed in south of Europe. And hummingbirds have only a long relationship with other birds currently breeding in the UK. Similarly, new breeding species in recent years, such as spoon birds and black wings, have also increased the development of British birds.

Researchers evaluated the data of a total of 8,768 bird species around the world to predict how many different species would disappear or increase in the region when they met the distribution of them. Although researchers predict species to reduce the most common in tropical and subtropical regions, the system development reorganization of species community will occur around the world. Their research emphasizes that protecting the diversity of local system development may be the key to the changes in environmental changes.

The main author of the study, Dr. Alke Voskamp, ​​a Senkeberg Biological Diversity and Climate Research Center, said: "In our research, we investigated the global warming to the world's land -raising to the world. The impact of the distribution of bird area. Among them, the focus of the survey lies in the impact of species richness and the impact on the diversity of system development, mainly to study how close the relationship between different species is. "

The co -author of the study, Professor Stephen Willis of Dulun University, said: "The diversity of species spectrum is usually related to the diversity of the characteristics of the species, and it is also related to their role and role in the ecosystem and the role and role of in the ecosystem Function is related. For example, species with far -sized blood relationships usually have different types of beak types, so they eat different types of foods. The changes in distributed areas means that the ecosystem function of birds performed in a region may change in the future in the future. This has a potential impact on the food network, seed communication and plant pollination. "At the same time, the study emphasized the importance of considering diversified measures when evaluating the impact of climate.
