Toxic turtles: Long-lasting chemicals could be harming sea turtles
From the moment they are born, sea turtles fight to survive. Buried alive, they dig themselves out and evade hungry crabs and birds as they crawl to the ocean, where they begin a long and treacherous migration. One out of 1,000 will survive into adulthood. And those that do will bear a toxic burden. Scientists are discovering that sea turtles, long ignored by toxicologists who study wildlife, are highly contaminated with industrial chemicals and pesticides.

Role of Kinship in Mass Strandings of Pilot Whales Questioned
Pilot whales that have died in mass strandings in New Zealand and Australia included many unrelated individuals at each event, a new study concludes, challenging a popular assumption that whales follow each other onto the beach and to almost certain death because of familial ties.
Using genetic samples from individuals in large strandings, scientists have determined that both related and unrelated individuals were scattered along the beaches -- and that the bodies of mothers and young calves were often separated by large distances.
... The mass stranding of pilot whales is common in New Zealand and Australia, involving several thousand deaths over the last few decades, according to Marc Oremus of the University of Auckland, who is lead author on the study. The researchers say their genetic analysis of 490 individual pilot whales from 12 different stranding events showed multiple maternal lineages among the victims in each stranding, and thus no correlation between kinship and the grouping of whales on the beach.

Pelican deaths now exceed 100 in Brevard
Outbreak cause baffles biologists
More than 100 parasite-infested brown pelicans died in Brevard County in the past two months. No one knows why. “The pelicans are emaciated and have heavy parasite counts, and, to our knowledge, other bird species have not been affected,” Dan Wolf, a researcher with the Florida Fish and Wildlife Conservation Commission, said in a release.
Many of the dead pelicans have turned up in Cocoa Beach. But others have been found on Merritt Island, in Melbourne, Indian Harbour Beach and along the St. Sebastian River.
FWC researchers are assessing specimens from the pelican carcasses and the environment to identify a potential cause.... “We suspect it may be botulism due to the warmer than average winter,” Sue Small, director of the Florida Wildlife Hospital and Sanctuary in Palm Shores, said earlier this week.
