能吃塑膠的麥皮蟲

澳洲科學家發現超級麥皮蟲,可以靠吃聚苯乙烯生存。 這些超級麥皮蟲腸道中有能分解塑膠的細菌。科學家想找出牠們腸道中的哪種酵素可降解塑料,希望能夠複製這種酵素,並找出更有效率的分解方法來幫助回收。

Australian scientists discovered Zophobas morio, also known as superworm, can survive on eating polystyrene. These superworms can feed the plastic to a bacteria in their gut. Scientists would like to find out which enzymes in their gut can degrade plastic, and hopefully can reproduce that enzyme to help recycling.

致病真菌影響鳳蝶存活

金鳳蝶是英國體形最大的蝴蝶,除了受到農業、氣候變化及林業的威脅外,牠們所食用的植物亦同樣面臨危機。 金鳳蝶的幼蟲以歐前胡為食,這種植物因致病真菌而大量死亡。 如果歐前胡消失,金鳳蝶也會於英國滅絕。

Swallowtail is Britains largest butterfly and they are at risk! beside threats from agriculture, climate change and forestry, their food plant is in danger because of a new disease. Its caterpillars feed only on the milk parsley plants and this plant is dying because of fungal pathogens. if the milk parsley disperse, the swallowtail will become extinct in Britain as well.

食用野生蛙危害生態

比利時及法國等歐洲國家對青蛙肉的需求,引致印尼、土耳其及阿爾巴尼亞共和國的部分蛙類面臨滅絕。 歐洲每年進口大約 2 億隻蛙類,主要為野生捕捉,導致野生青蛙種數量嚴重下降,影響生態平衡。

Some frog species in Indonesia, Turkey and Albania are facing extinction because of the demand for frogs meat in European countries like Belgium and France. Around 200 millions of frogs are imported each year in Europe, and mainly wild captured, causing serious declines in wild frog populations.

觀賞植物擴散成威脅

最近一項在美國俄亥俄州西南部的研究發現,金銀忍冬等入侵植物已蔓延到野外,並威脅到當地原生動植物的存活率。金銀忍冬於美國是原自歐洲及亞洲的觀賞植物,但已成為入侵植物。它的果實非常吸引雀鳥食用,並將種子散佈到新的地方。 在俄亥俄州一些林地,金銀忍冬已生長得非常茂密,只有一些生長在灌木層之上的原生樹能存活下來。

A recent study in southwest Ohio discovered that invasive plants like Amur honeysuckle, are spreading into the wild and is threatening the survival of native plants and wildlife. Amur honeysuckle is an ornamental plant native to Europe and Asia, but has became an invasive plant in the US. It has fruits that are attractive to birds to consume and help it disperse the seeds to new locations. in some woodlands, Amur honeysuckle is so dense that only some native trees that grow above the shrub layer survive.

寵物鳥成入侵物種

入侵物種紅嘴相思鳥與英國當地雀鳥如歐亞鴝及黑頭鶯等,有近似的生活、覓食、唱歌及築巢習慣,這可能對當地鳥類構成威脅。 紅嘴相思鳥原自於亞洲,因寵物貿易被帶到英國,並且被野放到林地及公園,除了英國,紅嘴相思鳥亦是歐洲部份地區如意大利及法國的入侵物種。

Invasive red-billed leiothrix has similar lifestyle, feeding, singing and nesting habits to British birds like robins and blackcaps, and could threaten these native bird population.  Red-billed leiothrix is native to Asia, but was brought to the UK as pets. These pet birds were released to the wild to woodland and parks. Beside the UK, red-billed leiothrix is also i an invasive species in some European countries like Italy and France.
