=====Climate crisis forecasts a fragile future for wildflowers and pollinators=====
[https://news.mongabay.com/2022/04/climate-crisis-forecasts-a-fragile-future-for-wildflowers-and-pollinators by  Spoorthy Raman on 1 April 2022 Mongabay]
A first-of-its-kind experimental study has found that climate change reduces the abundance of wildflowers and causes them to produce less nectar and fewer and lighter seeds.
These changes also impact pollinating insects visiting the flowers: they have to visit more flowers, more frequently, to gather the required food.
Fewer flowers imply reduced reproductive fitness in plants, as well as fewer food resources for invertebrates that rely on these plants for food, habitat and shelter.
Overall, climate change may disturb the composition of wildflower species and their pollinators, impacting agricultural crop yields, researchers say.
=====Mass die-off of birds in south-western US 'caused by starvation'=====
[https://www.theguardian.com/environment/2020/dec/26/mass-die-off-of-birds-in-south-western-us-caused-by-starvation-aoe The Guardian Phoebe Weston 12/26/20]
The mass die-off of thousands of songbirds in south-western US was caused by long-term starvation, made worse by unseasonably cold weather probably linked to the climate crisis, scientists have said.
Flycatchers, swallows and warblers were among the migratory birds “falling out of the sky” in September, with carcasses found in New Mexico, Colorado, Texas, Arizona and Nebraska. A USGS National Wildlife Health Center necropsy has found 80% of specimens showed typical signs of starvation.
Muscles controlling the birds’ wings were severely shrunken, blood was found in their intestinal tract and they had kidney failure as well as an overall loss of body fat. The remaining 20% were not in good enough condition to carry out proper tests. Nearly 10,000 dead birds were reported to the wildlife mortality database by citizens, and previous estimates suggest hundreds of thousands may have died.
=====Loss of bees causes shortage of key food crops, study finds=====

Of seven studied crops grown in 13 states across America, five showed evidence that a lack of bees is hampering the amount of food that can be grown, including apples, blueberries and cherries. A total of 131 crop fields were surveyed for bee activity and crop abundance by a coalition of scientists from the US, Canada and Sweden.
“The crops that got more bees got significantly more crop production,” said Rachael Winfree, an ecologist and pollination expert at Rutgers University who was a senior author of the paper, published by the Royal Society. “I was surprised, I didn’t expect they would be limited to this extent.”
