Scientists say unseasonal rains could have caused the mass deaths of Kazakhstan's endangered saiga antelope.
Nearly half of the world's population of the saiga - a species of antelope older than the mammoth - were wiped out by a freak pathogen last year, in an event scientists are blaming on rapid temperature fluctuations caused by climate change.

More than 200,000 of the saiga, a small antelope native to central Asia, died over the course of two weeks in Kazakhstan's Betpak-Dala region in May, pushing the critically endangered species to the brink of extinction.

In the run-up to this year's breeding season, scientists say that toxins - produced by an otherwise common bacteria that lives harmlessly in the respiratory tract of the saiga - may have been responsible for the sudden deaths.

Revealed: first mammal species wiped out by human-induced climate change
Exclusive: scientists find no trace of the Bramble Cay melomys, a small rodent that was the only mammal endemic to Great Barrier Reef
Human-caused climate change appears to have driven the Great Barrier Reef’s only endemic mammal species into the history books, with the Bramble Cay melomys, a small rodent that lives on a tiny island in the eastern Torres Strait, being completely wiped-out from its only known location.

It is also the first recorded extinction of a mammal anywhere in the world thought to be primarily due to human-caused climate change.

Wasps - where have they gone?
Today, for 5 hours we crushed grapes for wine making, outdoors. Not a single wasp (or hornet) came during the whole time. The mulch of skins and pips is still outside and still nothing. Normally it's a ferocious feasting time.
Similarly have seen almost no mosquitoes or horseflies and only a few hornets and bees all summer, but at least I did see some of these.

That cant be good OrganicSu. We live in Florida, about half way down the peninsula. We have an abundance of paper wasps here, building nests in the eaves and in our carport, as well as in our shed.

Sea cucumbers - where have they gone?
I live near a large, shallow, inland bay (circa 20km long by 10 km wide). Everywhere I used to swim had huge amounts of sea cucumbers. They are not a part of the Greek diet. There was maybe an average of 1 per sq meter. Some places had 3 or 4 per sqm. Potentially one of the most densely populated regions in the world for sea cucumbers.
One person eventually got the paperwork together to export to China. He employed many people to pick them up between December 2015 and March 2016. The bay is emptied of 'almost' all sea cucumbers. I have seen none. I say 'almost' because it is surely impossible they got every single one.

1 part of the food pyramid here was eliminated in 1 winter.

The fisherman have complained hugely of the lack of sardines and octopus in the bay this year but at least they have been at the elimination of those 2 species for much longer.

Caspian Terns follow record warm temperatures in 'shock' migration to north of Alaska
Researchers on north-west coast of Alaska startled to discover Caspian terns 1,000 miles farther north than species had been previously recorded
Eyebrows would be raised if American crocodiles, found on the southern tip of Florida, decided to relocate to New York’s Fifth Avenue or Moroccan camels suddenly joined the tourist throng outside Buckingham Palace in London. Yet this is the scale of species shift that appears to be under way in Alaska.

In July, researchers in Cape Krusenstern national monument on the north-west coast of Alaska were startled to discover a nest containing Caspian terns on the gravelly beach of a lagoon. The birds were an incredible 1,000 miles further north than the species had been previously recorded.

These crayfish & paua (the bumps of side of rocks =abalone) have suffered a climate change of a different sort: uplift from Sunday's 7.5 earthquake in NZ caused up to 2m of uplift on the shoreline of Kaikoura:

"Piles of dead turtle hatchlings are lining Queensland's famous Mon Repos beach amid a heatwave which has pushed the sand's temperature to a record 75 degrees Celsius."

Turtle hatchlings dying in extreme heat at Mon Repos
...
The rangers, scientists and volunteers at Mon Repos have been working around the clock to save as many clutches of hatchlings as they can from the heat.

Deceased turtles in the dunes lead them to the nests where some hatchlings may still be alive beneath the surface and they work quickly to dig them up, separating the dead from the living.

They are also relocating any new nests to hatchery areas underneath shade cloths, with sand surface temperatures under the shades up to 30 degrees cooler. ...

'It's the worst whale stranding we have ever seen'

Rescuers Fight to Save Hundreds of Pilot Whales Beached in New Zealand
Hundreds of volunteers formed a human chain in the shallows of a remote beach in New Zealand as they tried desperately to save hundreds of pilot whales that have beached themselves there.
...
Volunteer rescue group Project Jonah said 416 whales were stranded, and 75 percent of them had died by the time they were discovered. The Department of Conservation put the number of dead whales at 250 to 300. ...

This made me feel very bad: poachers are using scientific research to find, capture or kill endangered species

https://phys.org/news/2017-05-scientists-accidentally-poachers-rare-species.html

paper at doi:10.1126/science.aan1362

"Poaching has been documented in species within months of their taxonomic description in journals (4). For example, more than 20 newly described reptile species have been targeted in this way, potentially leading to extinction in the wild."

Must we humans eat all the world ?
