Dr Holden, Dr Rogers and Dr Yong conducted a census in shared homes and their backyards during the 2020 COVID-19 lockdown, collecting 1,150 endemic species of animals, plants and fungi over 12 months. discovered.
“We asked a number of ecologists and conservation scientists how many species they expected to find in this environment, and they predicted only 200 species.” Dr. Holden said.
“But after 60 days of research, we had already discovered 777 species.”
“It shows that suburban homes and apartments can contain much more biodiversity than previously imagined, especially when it comes to insects.”
The idea for species number came when Dr. Rogers went to vacuum the cobwebs in his room and wondered how many spiders there were on the premises.
“The three of us immediately came up with a plan to scour our homes and backyards looking for other creatures living with us,” Dr Holden said.
The survey revealed a rich biodiversity, including 436 species of moths and butterflies, 56 species of spiders, 8 species of reptiles, and 56 species of birds.
Bird species included yellow-brown black-breasted kingfishers, common kingfishers, green honeycreepers, rainbow parakeets, spotted doves and Brisbane’s favorite, the Australian white ibis.
“Blue-bellied skinks hibernated under the garage, and at night we had green-bellied bees and teddy bear bees sleeping in the hedge under the front window,” Dr Holden said.
Researchers were also surprised to discover three species not previously recorded in Australia’s major biodiversity databases. Living Australia Atlas — Mosquitoes, sandflies, invasive flatworms, Platypus ManokwariIt is responsible for the decline in populations of native snails around the world.
“The house was a complex ecosystem of interacting species – we encountered a moth Countless scat lacerations“The caterpillars spend their entire lives feeding in green mouse feces before emerging as adults,” Dr Holden said.
“Palyrgis conqueror This is another type of moth whose caterpillars live inside spider webs and eat spider feces to survive. ”
“All urban housing has the potential to host similar biodiversity.”
“It depends on how people take care of their homes and gardens. By keeping low-maintenance trees and shrubs, keeping well-maintained lawns and eliminating pesticides, you can increase the number of critters found. will increase significantly.”
“You don’t need to travel to connect with Australia’s biodiversity; you just need to look out into your own backyard.”
