			=====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.

			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.

			One of the lagoviruses of the family Caliciviridae causes a highly contagious illness called rabbit hemorrhagic disease. RHD is vexingly hard to diagnose. An infected rabbit might experience vague lethargy, or a high fever and difficulty breathing, or it might exhibit no symptoms at all. Regardless of the symptoms, though, the mortality rate for RHD can reach a gloomy hundred per cent. There is no treatment for it. The virus’s ability to survive and spread is uncanny. It can persist on dry cloth with no host for more than a hundred days; it can withstand freezing and thawing; it can thrive in a dead rabbit for months, and on rabbit pelts, and in the wool made from Angora-rabbit fur, and in the rare rabbit that gets infected but survives. It can travel on birds’ claws and flies’ feet and coyotes’ fur. Its spread has been so merciless and so devastating that some pet owners have begun referring to it as “rabbit Ebola.”

			=====Long-term predator–prey cycles finally achieved in the lab=====
			[https://www.nature.com/articles/d41586-019-03603-3 Nature 12-18-2019]
			A key question in ecology is what allows species to persist over time — particularly when there are pairs of species in which one is an exploiter and the other its victim. A long-standing theory attempts to answer this question by explaining how relative numbers of predators and their prey can cycle continuously1. First, prey numbers would increase, giving the predator more food. The subsequent increase in predators would lead to a decline in prey. Predator numbers would then decline owing to a lack of food, restarting the cycle. However, it has proved unexpectedly challenging to demonstrate this type of persistent predator–prey cycle in simple controlled systems in the laboratory. Writing in Nature, Blasius et al.2 report just such a demonstration, succeeding where almost 90 years of experimental work has failed.

			The challenge posed by such a demonstration was exemplified in 1934 by the ecologist Georgii Gause4, who studied the dynamics of two unicellular organisms — the predator Didinium nasutum and its prey, Paramecium caudatum. Gause found that, on the one hand, if the predator was efficient, it ate up all the prey and then starved. On the other hand, if part of the environment helped to conceal the prey, the predator was less efficient — and so starved (Fig. 1a). Coexistence and long-term cycles could be achieved only through artificial means — namely, by adding prey at regular intervals.

			The world’s leading scientists will warn the planet’s life-support systems are approaching a danger zone for humanity when they release the results of the most comprehensive study of life on Earth ever undertaken.

			Up to 1m species are at risk of annihilation, many within decades, according to a leaked draft of the global assessment report, which has been compiled over three years by the UN’s leading research body on nature.

			The 1,800-page study will show people living today, as well as wildlife and future generations, are at risk unless urgent action is taken to reverse the loss of plants, insects and other creatures on which humanity depends for food, pollination, clean water and a stable climate.

			The final wording of the summary for policymakers is being finalised in Paris by a gathering of experts and government representatives before the launch on Monday, but the overall message is already clear, according to Robert Watson, the chair of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES).
