And when they first arrived, we' d been there before, and they asked what dung beetles we' d seen. We said, " This this this." They said, " You can' t have seen that." So why not? They say, " Well. We know this place. We' ve studied here. It doesn' t occur here. It' s a lowland species and we' re at 1, 600 metres." So you' ve found a dung beetle in a piece of dung where it shouldn' t really have been? Exactly. That' s incredible. So that shows that climate change is affecting insects' ecology? Well yes, that' s right. It seems that insects are moving up mountains. Right. And of course insects live at particular zones of altitude and temperature, so if they all move up one, what happens to the ones that are already living in the top zone? Yeah. They don' t have anywhere to go, so it could be that this climate were to get warmer, we would start losing species that live on the tops of mountains. That' s something we conservationists need to be aware of. So it' s not always about finding a new species isn' t unknown to science, it' s about finding a species that shouldn' t be there, cos that' s a different story? That' s right, a lot of these are very wellknown, but we thought that we knew where they lived. And now they' re moving and living in different places and that' s interesting, ecologically. Why they' re doing that? |
