Aliens & Invaders & Exotics, Oh My: The Language of Invasive Biology

Language is important. It’s a lesson many biological scientists would have learned a long time ago if we hadn’t kept social sciences at such a wary arm’s length. Ecologists have a tendency to label and relabel ecological concepts (anyone up for a debate about the word ‘niche’?), species and even global phenomena (think global warming vs. climate change) based on anything from shifts in public perception to new findings that challenge our earlier labels.

Should We Conserve Hybrids?

The ultimate goal of species conservation is to preserve a species’ existence in the natural world. To effectively do this, we must know the extent of “species” that we want to conserve. That may sound simple, but the concept of hybridisation can blur the lines of where one species begins and another ends beyond recognition.

Fredrik Widemo: The Manifold Conflicts Behind the Hunting Industry

Rewilding is a tricky business. Bringing back species that once roamed a country as their native land may seem like a worthy cause, but it is often fraught with conflict. People don’t want predators threatening their safety, or herbivores destroying their crops. Rural vs. urban tensions come into play. Local and federal politics get thrown into the mix.

With that in mind, I sat down with Associate Professor Fredrik Widemo, currently a Senior lecturer with the Swedish University of Agricultural Sciences. Fredrik has previously worked at both the Swedish Association for Hunting and Wildlife Management (where he was the Director of Science) and the Swedish Biodiversity Centre. We explored some of the complexities behind the rewilding of wolves and its effects on the hunting and forestry industries in Sweden.

The reintroduction of wolves into Norway continues to incite controversy

Can you imagine a wild Scandinavia filled with untamed forests, wild boar, and large predators (and maybe a stray Viking)? This is the dream of some scientists advocating for the reintroduction of species once found in Europe that have either been hunted to extinction or driven out by intensive agriculture. The reintroduction of species, particularly animals dubbed “ecosystem engineers” such as beavers and large carnivores are of special interest due to the positive landscape-level effects of these species.
