Alien Species and Their Control

On The Potential Hostility of Alien Species

In this article we discuss the possibility that an extraterrestrial species could be hostile to humanity, and present estimates for the probability that visitors to the Earth will be aggressive. For this purpose we develop a generic model of multiple civilizations which are permitted to interact, and using randomized parameters we simulate thousands of potential worlds through several millenia ...

On the Statistical Mechanics of Alien Species

Many species of plants are found in regions to which they are alien. Their global 10 distributions are characterised by a family of exponential functions of the kind that arise in 11 elementary statistical mechanics (an example in ecology is MacArthur's broken stick). We show here 12 that all these functions are quantitatively reproduced by a model containing a single parameter – 13 some global...

Europe fisheries policy protest

The EU last month announced its allowable quotas for various species within its waters for this coming year that fishermen will be able to land and sell. The aim behind the quotas is to limit fishing in an effort to preserve stocks at sustainable levels, but the policy is being shown increasingly to be damaging many stocks, caught by fishermen pursuing one species but catching others, which oft...
