20、Everyone knows this: Slowly turn up the heat on a frog in a pot of water, and the frog won't hop out. Unaware of the slight increase in heat, it will stay put until — well, until it dies. When it comes to the effect of rising global temperatures on amphibians (两栖动物), the frog-boiling fable is more than just a metaphor (隐喻).
Climate change is becoming one of the biggest threats to frogs and other amphibians, according to a major study published Wednesday in the journal Nature. Between 2004 and 2022, rising temperatures became the primary reason why more than 100 amphibian species were slipping toward extinction.
The spread of disease among frogs and the destruction of their habitats have long been recognized as reasons why many amphibians are decreasing. But this new study establishes climate change as a major risk for amphibians around the world, too. The soft-skinned animals lack the fur and feathers to help adjust their temperature in this hotter and more drought-stricken world.
Less attention is paid to frogs and other amphibians compared to more well-known groups like birds. But losing amphibians would be disastrous because they often act as a key link in the food web of ecosystems, wolfing insects down and, in turn, being eaten by larger predators (捕食者)."Without those amphibians to fill that role, we will see the breakdown of this food web," said Neam, who works for an Austin-based environmental group.
Luckily, habitat protection and other conservation measures have been taken to help recover more than five dozen amphibians from Costa Rica to Malaysia. "It's not all bad news," said Jennifer Luedtke, an amphibian group leader of the International Union for Conservation of Nature. "But we really must build on this improvement and significantly increase investment in amphibian conservation."
