=====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. | |||

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. | 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.
