A Secret Ecosystem Under the Snow: The Winter World of the Subnivium

Sometimes the hardest places to access are the most interesting places to study. Take the subnivium, a temporary ecosystem that forms each winter in the small space between the snowpack and the ground.

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.

Ecology of the GoT Dragons

Adam and Sam talk macroecology and that’s pretty much it. How small would these dragons be? It’s very anti-climactic. We’ll do a supplemental later. Also SPOILERS. Though as we were a week behind, there’s some stuff that is currently incorrect re: the current status of the GoT dragons. Spoilers.

04:02 – Everyone’s Favourite Dragons
13:15 – The Ecology of the Dragons
40:13 – Balerion the Big Boi vs. The US Military

And as usual, you can check out last week’s podcast on the physiology of these flappy flaps flaps below.

Episode 3: A Quiet Place

We dive into the quiet B O I S from 2018’s A Quiet Place. Dave think lions are from Antarctica, Adam gets too damn excited by Alligator gar and Sam’s stepson ruins the episode.

Bringing Back the Wolverine

The Crux

Humans have a long history of driving dangerous predators out of their backyard. Wolves and wolverines have been driven out of different parts of Europe at different points in history at the behest of farmers looking to protect their livelihood, and the Tasmanian Tiger was driven to extinction for the same reason. But with the realisation that these predators bring enormous ecosystem benefits, governments have been searching for ways to bring about co-existence between predators and locals.

This study looks at a scheme introduced by a Swedish government in 1996, where reindeer herders had previously been compensated for any wolverine related losses. The new scheme introduced compensation for successful wolverine reproductions in the area. Persson et al. decided to have a look at how it fared.

Rewilding

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.

The Wild Boar

In this series we’ll be mainly dealing with alien species invading new parts of the world. However it’s important to recognise that not all invasive species are alien to the territories they invade, and not all invasive species are unanimously unwelcome. Today, we look at a species that is now returning to its former native territory, and which is being welcomed back by some.
