每日英語跟讀 Ep.854: About nature - Nature crisis: ’Insect apocalypse’ more complicated than thought
Previous research indicated an alarming decline in numbers in all parts of world, with losses of up to 25% per decade. This new study, the largest carried out to date, says the picture is more complex and varied.
Land-dwelling insects are definitely declining the authors say, while bugs living in freshwater are increasing. The overall picture is complex - even in close geographical areas, some insects can be doing well next door to members of the same species who are struggling.
Ann Swengel, one of the authors on the paper has spent more than 30 years studying butterflies in parts of the US. "We’ve seen so much decline, including on many protected sites. But we’ve also observed some sites where butterflies are continuing to do well," she said. "It takes lots of years and lots of data to understand both the failures and the successes, species by species and site by site."
Deserted Thai beaches lure rare turtles to build nests 人跡罕至的泰國海灘吸引稀有龜類築巢
Thailand has found the largest number of nests of rare leatherback sea turtles in two decades on beaches bereft of tourists because of the coronavirus pandemic, environmentalists say.
The 11 turtle nests authorities have found since last November were the highest number in 20 years, said Kongkiat Kittiwatanawong, the director of the Phuket Marine Biological Center.
"This is a very good sign for us because many areas for spawning have been destroyed by humans," he told Reuters. No such nests had been found for the previous five years.
"If we compare to the year before, we didn’t have this many spawn, because turtles have a high risk of getting killed by fishing gear and humans disturbing the beach."
Leatherbacks are the world’s largest sea turtles. They are considered endangered in Thailand, and listed as a vulnerable species globally by the International Union for Conservation of Nature.
