A series of mild winters has seen swarms of brown tail moth caterpillars move from their usual habitats along the south-east coast to as far north as Yorkshire.
The brown and red grub is covered in millions of tiny hairs that contain a toxin that can cause painful rashes, eye infections and, if inhaled, serious breathing difficulties.
As the caterpillars have moved inland, environmental health officials have been putting up warning signs in popular beauty spots.
The Californian researcher has called for owners to keep their cats indoors.
Cat faeces carrying Toxoplasma parasites wash into US waterways and then into the sea where they can infect otters, causing brain disease.
The parasite is familiar to medical researchers, as it can damage human foetuses when expectant mothers become infected while changing cat litter.
What is causing many California sea otters to become weak, disoriented, and even unable to eat properly? The answer may hint at trouble for humans too.
"The overall number of dead seals as of Friday night reached 724, including 528 baby seals," the ministry said. "The coast is continuing to be monitored."
The dead seals have been found along the seashore between two major oil fields in western Kazakhstan. But officials in Kazakhstan cite weather conditions as a possible reason.
"Until February 20, most of the northeastern Caspian did not freeze, and on February 21-22 the northern Caspian had a covering of thin ice that melted by March 20. It could have had a negative effect on the baby seals," the Ministry of Environmental Protection said earlier.
Over the past two months, farmers in three parts of Taiwan have reported most of their bees gone, the Chinese-language United Daily News reported. Taiwan's TVBS television station said about 10 million bees had vanished in Taiwan.
A beekeeper on Taiwan's northeastern coast reported 6 million insects missing "for no reason", and one in the south said 80 of his 200 bee boxes had been emptied, the paper said.
Beekeepers usually let their bees out of boxes to pollinate plants and the insects normally make their way back to their owners. However, many of the bees have not returned over the past couple of months.
The infestation by varroa mites has led the state to ask beekeepers to restrict transport of bees around the islands. There are concerns it could threaten the Big Island's thriving queen bee export industry, which has so far tested free of the mites.
"This is going to be for us a nightmare," said Michael Kliks, head of the Hawaii Beekeepers' Association and owner of Manoa Honey Co. "When I saw that mite I knew exactly what it was. I knew exactly what it meant and I fell to my knees and almost began to weep because it's inexpressible what that sea change is for us in Hawaii."
The parasites are blamed for destroying more than half of some mainland beekeepers' hives and wiping out most wild honeybees there.
