Despite the extreme environment, Australia’s iconic Lake Eyre Basin is home to a range of aquatic animals(水生物)—including fish. In fact, during massive floods, the desert is teeming with them. But such flood events are very rare. So, how do fish survive in the【C1】______?
A new study led by Monash University researchers has revealed that for one fish species, the desert goby(霞虎鱼), survival hinges on【C2】______moving to new water sources. Lead researcher Krystina Mossop explained that despite their small size and poor swimming ability, desert gobies use short-lived flood events to move between locations. "This is important because desert waterholes are constantly【C3】______up, and to survive in the long term, the fish need to constantly track the【C4】______of water in their environment," Ms. Mossop said.
To explore how the fish moves around its arid landscape, the researchers drew on the information【C5】______in the goby’s DNA: an excellent tool because it captures signatures of past environments in modern organisms. "By mapping the【C6】______variation of populations across the landscape, we can see which populations are more connected, and which are more【C7】______. This lets us identify where there are barriers that stop fish from moving between locations," Ms. Mossop said.
By studying the goby’s DNA, the researchers discovered that gobies from very different parts of the landscape were genetically【C8】______, demonstrating that populations are much more connected than anticipated. "What this probably shows is that because gobies are tough little fish, they can survive in drying and shallow water long enough to’ leapfrog’their way across the landscape," said senior co-author, Associate Professor Bob Wong, also in the School of Biological Sciences at Monash University. It’s that same’ little battler’character that allows them to use the harsh waters that exist during extended【C9】______periods.
"These findings have【C10】______for conserving species like the desert goby, and related fish that are endangered by habitat loss and degradation through human use of the desert’s scarce water resources," said senior co-author, Dr. David Chapple.
A)connected B)constantly C)desert D)different
E)drought F)drying G)flood H)genetic
I)implications J)isolated K)location L)meantime
