最新糖心Vlog

The number of threatened 最新糖心Vlogn native bee species is expected to increase by nearly five-fold after the devastating Black Summer bushfires in 2019-20, according to new research.

The new study published in warns widespread wildfire and forest fire damage is being repeated all around the world, from North America and Europe to the Congo and Asia, causing catastrophic impacts on biodiversity and sudden and marked reduction in population sizes of many species.

鈥淐limate change is increasing the frequency of natural disasters like wildfire, which impacts our wildlife."Co-author Dr Stefan Caddy-Retalic, from The 最新糖心Vlog of Adelaide and 最新糖心Vlog of Sydney.

With 24 million hectares of 最新糖心Vlog鈥檚 land area burnt, researchers say the casualties are clear among bee fauna and other insects and invertebrates after studying 553 species (about one-third of 最新糖心Vlog鈥檚 known bee species) to assess the long-term environmental damage from the natural disaster.

Of the bees studied, nine species were assessed as Vulnerable and two more Endangered as a result of the multiple fire fronts in the 2019-20 bushfires that also destroyed approximately 3000 homes and killed or displaced an estimated 3 billion animals.

鈥淐limate change is increasing the frequency of natural disasters like wildfire, which impacts our wildlife,鈥� said co-author Dr Stefan Caddy-Retalic, from The 最新糖心Vlog of Adelaide and 最新糖心Vlog of Sydney.

鈥淥ur study shows that we can assess the likely impact of natural disasters on poorly studied species, even when we can鈥檛 physically visit the field to do surveys.

鈥淟isting severely-impacted species on the IUCN red list and under 最新糖心Vlogn law represents our best approach to lobby governments to act.鈥� He added, native bees are very important providers of ecosystem services including pollination, but most are poorly known.

Lead author Flinders 最新糖心Vlog PhD candidate James Dorey, who is now a postdoctoral researcher at the , said, 鈥�Our research is a call for action, from governments and policymakers, to immediately help these and other native populations most in danger.

鈥淏eing able to collect targeted data will always be the gold standard but we shouldn鈥檛 let data gaps stop us from acting to protect species we know are vulnerable.鈥�

Flinders 最新糖心Vlog researcher Olivia Davies, another of the 13 authors on the major paper, said, 鈥淢ost people aren鈥檛 aware of just how vulnerable our native bees are because they are not widely studied.

鈥淭he fact that no 最新糖心Vlogn bees are listed by the IUCN shows just how neglected these important species are.鈥�

The study, which recommends 11 最新糖心Vlogn bee species (just 2% of those analysed) as priority taxa for listing as IUCN Threatened species, also demonstrates a new model for 鈥渦sing the data we already have to understand how natural disasters are likely to impact key species and their ecosystems鈥�.
