SAO PAULO (AP) — More than 100 dolphins have died in the Brazilian Amazon rainforest in the past week as the region grapples with a severe drought, and many more could die soon if water temperatures remain high, experts say. Experts believe high water temperatures are the most likely cause of the deaths in the lakes in the region. Temperatures since last week have exceeded 39 degrees Celsius (102 degrees Fahrenheit) in the Tefe Lake region. There had been some 1,400 river dolphins in Tefe Lake, said Miriam Marmontel, a researcher from the Mamiraua Institute. Fleischmann said water temperatures rose from 32 C (89 F) on Friday to almost 38 C (100 F) on Sunday.

REUTERS/Bruno Kelly/File photo Acquire Licensing RightsMANAUS, Oct 2 (Reuters) - The carcasses of 120 river dolphins have been found floating on a tributary of the Amazon River since last week in circumstances that experts suspect were caused by severe drought and heat. Low river levels during a severe drought have heated water in stretches to temperatures that are intolerable for the dolphins, researchers believe. The Amazon river dolphins, many of a striking pink color, are unique freshwater species found only in the rivers of South America and are one of a handful of freshwater dolphin species left in the world. The scientists do not know with total certainty that drought and heat are to blame for the spike in dolphin mortality. Global warming's role in the current Amazon drought is unclear, with other factors such as El Nino at play.
