The article reports on the ecological impact of cane toads in Australia. In 1935, the cane toad (Bufo marinus) was introduced into the sugar cane plantations in northern Queensland, in an unsuccesful attempt to control sugar-cane bettle (Dermolepida albohirtum) pest. Cane toads are reportedly...
Australian Rhinella marinus occurrences in the GBIF database About Dataset Cane toads were introduced into Australia in 1935 in an attempt to control native cane beetles, a pest of sugarcane. The toads are now a pest and are estimated to number over 200 million. ...
Cane toads in Australia now number into the millions, and their still-expanding range covers thousands of square miles in northeastern Australia. In addition to Australia, cane toads have spread in Florida, Hawaii, Guam, the Philippines, the Caribbean islands, the western Pacific islands, Papua ...
短文开头提到,蔗蟾(cane toads)是引入澳大利亚的最不同寻常的动物,1935年种植甘蔗的农民引进蔗蟾是为了去除危害甘蔗的蔗虫(to getrid of the beetle which kills the sugar cane plant),故答案为[B]。1、文中提到,在30年代中期,蔗虫泛滥(there was a serious outbreak of the cane beetle),这让农夫们很绝望...
Cane toads (Rhinella marina) have been spreading across Australia since the late 1930s, evolving novel morphologies and behaviours that have accelerated their rate of dispersal3. These traits include faster individual growth rates, increased relative leg length and higher endurance4,5 in toads at the...
One of the most intensively studied invasive taxa in this respect is the cane toad (Bufo marinus), which was introduced to Australia in 1935. A review of these studies suggests that a single pathwaylethal toxic ingestion of toads by frog-eating predatorsis the major mechanism of impact, but ...
Maladaptive traits in invasive species: in Australia, cane toads are more vulnerable to predatory ants than are native frogs 喜欢 0 阅读量: 19 作者: Georgia Ward-Fear,Gregory P. Brown,Matthew J. Greenlees,Richard Shine 摘要: 1. If a species is translocated outside its native range, some ...
. If it is Cane Toad related and you don't see it here, by all means, drop us a note and we'll see what we can do to offer it in the future. If you would like to know more about the man-made natural disaster happening in Australia please check outThe Story of Cane Toads....
n Australia, invasive cane toads(Bufo marinus)are highly toxic to native snakes. Snakes are gape-limited predators, so the arrival of toads may exert selection on snake morphology, which is quantified using relative head size. For each section be...
With the toad invasion front rapidly nearing the city of Darwin, capital of Australia’s Northern Territory, researchers found that cane toads were advancing much faster than in the early years of colonization. Sixty years ago the toads were extending their range by about 10 km (6 miles) per...
