Scientists Find Three Viruses to Control Cane Toads

Cane toads are a pest in Australia. They were introduced to kill beetles attacking sugar cane. Unfortunately, they were not interested in the beetle. They ate just about everything else. Native species have been greatly depopulated. Now, their DNA has been sequences. Furthermore, three viruses that destroy only cane toads have been identified.

Times are a changin', as the saying goes. And it is not always for the best. Trapdoor spiders are getting fewer in South Australia. They balance the ecosystem, so their loss is a bad thing.  If they do not eat beetles, for example,  the Coleopltera will run amok. | not. |◀|

Surveys on the numbers show a sharp decline. In 18 days in the 1950s 122 specimens were found. A search in 2014 caught only 18 in ten days. No research has been done to see what is happening nationwide. | ▶ | not. | ▶ |

The arachnid has its weaknesses. Each builds its burrow when it is immature. The retreat is home for its whole life. If the lair is damaged it cannot be rebuilt. Its positive point is longevity: it can live for 30 years.| ▶ | not. | ▶ |                                      | ▶ not | ◀ |
