TELC angol B2 nyelvvizsga nyelvtan feladat: Dolphin deaths on Gulf Coast alarm scientists
NEW ORLEANS — Scientists are trying to figure out … (1) killed 53 bottlenose dolphins — many of them babies — so far this year in the Gulf of Mexico, as five more of their carcasses washed up Thursday in Louisiana, Mississippi and Alabama. It’s likely … (2) months before they get back lab work showing what … (3) the spontaneous abortions, premature births, deaths shortly after birth and adult deaths said Blair Mase, the National Oceanic and Atmospheric Administration’s stranding coordinator for the Gulf Coast. “It’s not like CSI where the … (4) next day they have the results in. It doesn’t work that way, unfortunately,” she said.
Calves and fetuses made up at least 85 percent of the deaths in Alabama, 60 percent or more of those in Mississippi and Florida and 20 percent in Louisiana, according to NOAA figures. The Mississippi and Alabama deaths are in areas where bottlenose dolphins go to calve, said Moby Solangi, director of the Institute for Marine Mammal Studies in Gulfport. Solangi said he … (5) anything like the calf deaths, or found word of anything like it in 30 years of records from his area — Alabama, Mississippi and east Louisiana. … (6), Mase said 68 dolphins that washed up in east Texas in March 2007 also included an unusually large number of calves. The bodies were too decomposed to find the cause, she said.
Although scientists are investigating whether the deaths are related to last year’s huge BP oil spill, they say toxins from oil or chemicals used to disperse it are considered a less likely cause … (7) cold or disease. That’s because only one species of dolphin — and no other kind of animal — is dying, and because the calf deaths appear concentrated in Mississippi and Alabama rather than Gulf-wide. The dolphins found Thursday include three off Louisiana and one each off Mississippi and Alabama, NOAA spokeswoman Kim Amendola said. The bodies … (8), so ages and sizes were not known, she said.
Since Jan. 1, 19 dead dolphins have been found … (9) Louisiana, 16 off Mississippi, 15 in Alabama and three in the Florida Panhandle. Mississippi and Alabama usually each see two to four … (10) strandings a month at this time of year, Mase said. Solangi said only six of the 23 calves found by Wednesday in Mississippi and Alabama were in good enough condition for a necropsy, the animal version of an autopsy. “We’ve collected tissues and sent them off to various laboratories for pathology and toxicology,” he said. “All we can tell is some of them may have been premature, some of them were stillborn and others may have just survived for a day or two and died.” Dolphins usually calve in March and April, he said. Because those areas are remote, there’s no way to know the true numbers of dolphin strandings and deaths. “The number is not absolute — just a kind of barometer,” Mase said.
