Homalictus Terminalis: New Bee Species Discovered Is Already at Risk of Extinction From Climate Change

  Homalictus Terminalis: New Bee Species Discovered Is Already at Risk of Extinction From Climate Change H. Terminalis is among nine newly identified bee species which are described in a study published in the journal Zootaxa. The new species all belong to the genus known as Homalictus Cockerell, which scientists have not reviewed in Fiji from a taxonomic perspective for 40 years."These field trips have allowed us to redescribe four known species and describe nine new ones, bringing the number of endemic Homalictus in Fiji to 13 species," Mark Stevens, one of the authors of the study from Flinders, said in a statement.The new species described in the study are named H. atritergus, H. concavus, H. groomi, H.

A new assessment shows that more than half of the trees only found in Europe are at risk of extinction . However, when looking at the species endemic to Europe —meaning they don’t exist anywhere else on the planet—58 percent face extinction mostly due to invasive species and pests.

A new assessment shows that more than half of the trees only found in Europe are at risk of extinction . “It is alarming that over half of Europe ’s endemic tree species are now threatened with extinction ,” Craig Hilton-Taylor, who leads the IUCN Red List Unit, said in a statement.

A new assessment shows that more than half of the trees only found in Europe are at risk of extinction.

The International Union for Conservation of Nature (IUCN) released a list of trees that are struggling to get by on the continent this week. Out of the 454 tree species native to Europe, two-fifths are regionally threatened with extinction.

However, when looking at the species endemic to Europe — meaning they don’t exist anywhere else on the planet — 58 per cent face extinction mostly due to invasive species and pests. Some 15 per cent are already critically endangered, which is the closest a species can be to extinction.

Greece to Overhaul Asylum Process After Deadly Refugee-Camp Fire

  Greece to Overhaul Asylum Process After Deadly Refugee-Camp Fire Greece vowed to reduce overcrowding at camps for asylum-seekers on its Aegean islands, after a deadly fire on Sunday highlighted the country’s growing struggle to cope with refugees and other migrants trying to reach Europe. Prime Minister Kyriakos Mitsotakis’s new conservative government promised to speed up decisions on who gets asylum, return more rejected applicants and move some asylum-seekers to the Greek mainland from islands such as Lesbos where overflowing refugee camps are causing mounting unrest. require(["inlineoutstreamAd", "c.

Find out why so many trees in Europe are facing extinction and what can be done to help save these native tree species. “It is alarming that over half of Europe ’s endemic tree species are now threatened with extinction ,” said Craig Hilton-Taylor, head of the IUCN Red List Unit.

“It is alarming that over half of Europe’s endemic tree species are now threatened with extinction,” Craig Hilton-Taylor, who leads the IUCN Red List Unit, said in a statement.

“Trees are essential for life on earth, and European trees in all their diversity are a source of food and shelter for countless animal species such as birds and squirrels, and play a key economic role.”

Some of these tree species at risk include the Heberdenia excelsa, a shrub that can grow to the heights of a tree on the islands of Spain and Portugal that is dealing with severe habitat loss from bushfires and human use; Sorbus albensis, another shrub-like tree which bears orange-red fruits that have trouble growing in the changing forest of the northern Bohemia region of the Czech Republic; and the Serbian Spruce, a conifer that flowers distinct purple cones in Bosnia and Herzegovina and Serbia.

Ancient 45,000-year-old quartz tools 'used to hunt animals up trees' are found in Sri Lanka - making them the oldest human-made implements ever found in South Asian rainforest

  Ancient 45,000-year-old quartz tools 'used to hunt animals up trees' are found in Sri Lanka - making them the oldest human-made implements ever found in South Asian rainforest Archaeologists led from the Max Planck Institute in Germany and colleagues analysed microliths, from the west Sri Lankan cave of Fa-Hein Lena, that date back to around 48,000-45,000 years ago.Archaeologists had previously thought that rainforests presented a barrier to the early spread of humankind.

Other species facing extinction in the European continent includes terrestrial molluscs, bryophytes and shrubs. The report says 2,469 species of terrestrial molluscs, which are endemic to the European continent, risk extinction . A decline in Europe 's ecosystem is due to a number of factors

The trees face a number of different threats, but “invasive or problematic species” sit at the top, per the new report. Pests, such as the leaf-miner moth that damages trees such as the horse-chestnut, affect 38 per cent of European tree species. Deforestation, wood harvesting and urban development follow as major risk factors.

Climate change, however, is a major threat, too. Its impacts still aren’t all that well-understood and could be underestimated, the report states. The report authors understand it’s a threat to all tree species, but it’s only included in the report where its impacts are already apparent — such as with the Serbian Spruce.

Other recent research about the tree also indicates it could disappear in the “near future” without further interventions such as assisted migration. Currently, climate change directly threatens about 50 tree species.

Any plants and trees imported into Europe need to be carefully vetted to ensure more pests aren’t entering the region, according to The Guardian. That’s especially true as countries look to trees as carbon sinks to offset their greenhouse gas emissions.

Trees in Europe are but one victim to humans and the far-reaching impacts of our actions. Other species — from frogs to birds — are suffering, too. That’s on us.

Tram strike cancelled over 'unpredictable' Extinction Rebellion .
A tram strike planned for Thursday has been called off because of the "unpredictable" climate protests in the Melbourne CBD.About 1500 drivers were due to walk off the job between 10am and 2pm on Thursday but the Rail Tram and Bus Union has agreed to withdraw the stoppage because of Extinction Rebellion action.
