Fiji Bee Biodiversity Barometer ̵
1; New Species Described as Environmental Change
The biodiversity physics are alive and well in Fiji, but climate change, harmful weeds and multiple weeds activities make extinction possible
Just as Australian researchers have discovered colorful new bee species, some are already showing signs of exposure to environmental changes.
University of Flinders doctoral candidate James Dorey – whose closeup has captured some of Fiji's newest honeybee species – says naming nine new species allows researchers to highlight the risks.
'Homalictus terminalis is so named to indicate that, like many Fijian bees, it is close to its border and exposed to extinction related to climate,'
where many tourists start their holidays, H. terminalis is only found within 95 meters of the mountain peak. "
Students from South Australia under the Australian Government's Abroad Study Program Abroad have traveled to Fiji in the Southwest Pacific for several years, naming nine new species in one of their recent research publications in Zootaxa .
The impressive black Homalictus achrostus, which is characterized by unusual large mandibles, is one of Fiji's most interesting endemic species.
But, like many species of Fijian bees, H. achrostus has
"Six people were gathered on Nadarivatu Mountain in the 1970s and two in 2010, but despite frequent searches almost every year since they were no longer found "Says Associate Professor Flinders University's Mike Schwartz, co-author of the paper.
"The probable driver of this possible extinction is climate change," says Assoc. Schwartz.
"The cooler climate of the Fiji Mountains can be slowly pushed up and up the mountains, carrying with them the species that need this climate shelter.
"With H. achrostus one of the four previously described species of endemic bees in Fiji, this creates real concerns about the extinction of many highland species in Fiji and throughout the tropics. "
A senior researcher of terrestrial invertebrates at the Museum of South Australia, Dr Mark Stevens, says that the bee genus Homalictus Cockerell was not a taxonomic review ed. in the Fiji archipelago for 40 years.
"These field trips allowed us to transcribe four known species and to describe nine new ones, bringing the number of endemic homalacts in Fiji to 13 species," says Dr. Stevens, who is collaborating. of the study.
"Most of the species diversity (11 species) live 800 meters or more above sea level, highlighting the vulnerability of highland species to warm climates."
One of the new species of attention-grabbing Homalictus groomi is named in honor Flinders Biology graduate Dr. Scott Garham, who began to discover this hidden diversity using molecular techniques with the University of Flinders and the South Australian Museum in 2009.
