According to one, the number of wild bee species recorded by an international database of life on Earth has declined since 1990. Global analysis of bee declines.
Researchers analyze bee records of museums, universities and civil scientists Global Biodiversity Information Facility, (GBIF) is a global, government-funded network that provides open-access data on biodiversity.
They reported about 25 percent fewer species since 1990, a steep decline in bee species since 1990, with about 25 percent fewer species.
While this does not mean that these species are extinct, it may indicate that some have become so rare that they are no longer regularly seen in the wild.
“With citizen science and data sharing capability, records are growing rapidly, but the number of species reported in these records is decreasing,” lead author and Universidad Naquin del Comahu and national biologist Eduardo Jattara of Argentina he said. Council of Scientific and Technical Research. “It is not yet a bee holocaust, but what we can say is that wild bees are not there at all.”
A different series of scientific studies in global insect moths Warned this month That the abundance of pests was declining by 10 to 20 percent each decade, an “absolutely horrific” loss that threatened to “tear the tapestry of life”.
In the US, a study in 2020 found that there is a shortage of bees in agricultural areas Was restricting the supply of some food crops. In Britain, this month the government Allowed farmers to use nicotinoids On beet crops despite bee killing pesticides Banned in the European Union Together in 2018 UK support.
The new study, published in the journal One earth, Records from three centuries of collection were analyzed, including more than 20,000 known bee species worldwide.
It was found that the decline in bee families was not evenly distributed. While record Halidid Bees, the second most common family, have declined by 17 percent since the 1990s. Melittidae– A very rare family – more than 41 percent have fallen.
Scientists warn that the lack of scientific data on the decline of pests in tropical countries is hindering their understanding of global bee declines, including most GBIF records in North America and Europe.
The authors of the study acknowledged that species decline may reflect changes in the collection of GBIF data over time or the heterogeneous character of its dataset.
Jattara said that while his study did not establish the status of individual bee species, it showed a clear global trend with decreasing diversity of species to indicate a global decline in bees and other pollinators.
“It is about confirming what is happening globally,” he said. “And also, about the fact that much better certainty will be achieved as more data is shared with public databases.”
He warned that waiting for data to confirm the bee type and the decline of bee types and other pollinators may be too late to protect them.
“Something is happening to the bees, and something needs to be done. We cannot wait until we are definitely full because we rarely meet in the natural sciences, ”he said. “The next step is getting the policy makers in action while we still have time. The bees can’t wait. “
