Are salamanders an important feeding source for pitcher plants?

蝾螈是猪笼草的重要食物来源吗？

That's right, plants that eat stuff, like venus fly traps, pitcher plants.

没错，吃东西的植物，例如捕蝇草，猪笼草。

A pitcher plant's leaves usually form a tall, narrow pocket that can hold liquid.

猪笼草的叶子通常会形成一个又长又窄的" 口袋" ，里面可以储存液体。

Meat-eating pitcher plants have been known since the eighteenth century, the University of Guelph says.

圭尔夫大学表示，食肉猪笼草早在18世纪就为人所知。

They could have died from proteins produced by the pitcher plants that are held in liquid inside the leaves.

导致蝾螈死亡的可能是猪笼草叶子内的液体所分泌的蛋白质。

The pitcher plant is shaped like a vase - insects go inside and then cannot crawl up the slippery insides.

猪笼草的形状像一个花瓶——昆虫进入到里边，在光滑瓶身内无法向上爬行。

The researchers say pitcher plants clearly get a lot more nutrients from salamanders than from insects and spiders.

研究人员表示，相比于昆虫和蜘蛛，猪笼草显然能从食用蝾螈中获得更多养分。

Insects and spiders that enter the pocket often become trapped and the pitcher plant then feeds on their bodies.

进入这一" 口袋" 的昆虫和蜘蛛会被困在里面，然后猪笼草会吃掉它们的尸体。

Pitcher plant mosquitoes have rapidly evolved to take advantage of the warmer temperatures, entering dormancy later and later in the year.

猪笼草蚊快速地进化它们越来越晚的进入冬眠，以利用更加温暖的天气。

However, when the plants are low on live food supply, Collingsworth suggests adding some fertilizer to each pitcher plant's " mouth" .

然而，当植物缺乏活饵料供应时，科林斯沃斯建议给每个猪笼草的" 嘴巴" 加一些肥料。

Pitfall traps are the standard passive trap used  by things like pitcher plants and bromeliads.

陷阱是猪笼草和凤梨科动物使用的标准被动陷阱。

He told Canada's CTV News the research station near the bog where the pitcher plants were observed has been there for 70 years.

他对加拿大 CTV News表示，沼泽附近有一个观察猪笼草的研究站，而这家研究站已经设立了70年。

Pitfall traps are the standard passive trap used by things like pitcher plants and bromeliads.

Meanwhile, the pitcher plants of North and South America seem to have originated  around 48 million years ago.

与此同时，北美和南美的猪笼草似乎起源于大约 4800 万年前。

The research team said it believes this is the first time any North American pitcher plants have been observed feeding on anything besides insects or spiders.

研究小组表示，他们认为这是研究人员首次观察到北美地区的猪笼草食用除昆虫或蜘蛛以外的生物。

During visits to a single area of the park in fall of 2018, the research team found almost one in five pitcher plants contained young salamanders.

研究小组在2018年秋天考察了该公园的一个区域，他们发现几乎有五分之一的猪笼草里都有被困住的蝾螈幼崽。

In September of last year, a video showing a jumping spider living in a pitcher plant quickly got 15.8 million views after it was posted to TikTok.

去年9月，一段视频展示了一只生活在捕虫草中的跳蛛，这段视频在TikTok上发布后，很快就获得了1580万的点击量。

In the summer of 2017, then University of Guelph student Teskey Baldwin found a salamander trapped inside a pitcher plant while doing field work in the provincial park.

2017年夏天，当时在圭尔夫大学就读的学生特斯基·鲍德温在阿岗昆省立公园进行实地考查，他发现一只蝾螈被困在了猪笼草中。

That prey is usually insects, though  sometimes it includes small vertebrates, like the northern pitcher plants that  have been observed consuming salamanders.

猎物通常是昆虫， 但有时也包括小型脊椎动物，例如已观察到食用蝾螈的北方猪笼草。

Insectivorous plants, like venus fly traps,   butterwort, sundew and pitcher plants, which we've talked about on the channel,   catch and digest bugs for nutrients.

我们在频道上讨论过的食虫植物，如金星捕蝇器、蝴蝶草、太阳露和猪笼草，可以捕捉和消化虫子以获取营养。
