The Crux

We’ve talked a lot about Island Biogeography Theory (IBT) in the last couple of weeks. One of the key tenets, established way back in the 60s, is that as an island’s area decreases, its species richness tends to as well. Yet since IBT was conceptualised, there have been a number of amendments made to it. The Small Island Effect (SIE) is one of them.

SIE essentially means that below a certain threshold (called a ‘breakpoint’), species stop obeying that species richness to area relationship. This week’s researchers wanted to test whether that breakpoint was different between species groups, and whether the species area relationship changed below that breakpoint, or simply disappeared.

Why Pseudoscience Gives Me Nightmares

Whilst pseudoscience is nothing new, it seems a lot more prevalent these days. So what can the scientific community, and the public in general, do about it? (Image Credit: Becker 1999, CC BY 2.0, Image Cropped)

Fake science – or pseudoscience – has been around forever and somehow like that really annoying guy at the party just won’t go away. How is it in an age ruled by smart phones and CRISPR sci-fi level biotech are people still buying crystals and talking about super foods (don’t get me started on Goop). While I try to adopt a Californian “you do you” attitude to almost everything, people purporting even the most innocuous pseudoscience need to be stopped by both you and me.
