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.

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.

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.

Why support bringing species back?

Reintroducing species, or rewilding, can have effects well beyond making hippies in Green Peace happy. The reintroduction of beavers in the UK, for example, has reduced flooding in Devon, and the reintroduction of wild boar in Sweden has led to an increase in plant species across habitat types where the wild pigs rooted. The reintroduction of wolves to Yellowstone National Park in my home country the good old US of A has led to the natural regulation of deer and elk populations, in turn leading to more diverse forests as grazing of seedlings decreased.

Why not reintroduce species?

Reintroducing species has understandably led to controversy. Sure, wolves are cool-until they eat your sheep. Since wolves were reintroduced to Yellowstone in the 1990s, locals have protested citing safety concerns, the loss of livestock, and a decreasing population of elk for hunters. In Sweden, the boom in wild boar numbers has led to destruction of crops, and much outcry from farmers. Having protected species on land also makes it harder for companies to extract natural resources, both from a political and practical perspective (image a miner facing off with a bear).

The future of reintroducing species in Scandanavia

Species that are either being reintroduced in the UK and US or are under consideration are being hunted to extinction in Scandinavia. Norway, a country known for leading the change in environmental issues, is mired in debate over maintaining their current populations of large carnivores like wolves and wolverines. It seems unlikely that sheep farmers that have pushed for the cull of wolves to protect their flocks would support bringing in any more large animals that might pose a threat to their economic well being. If a species like wild boar are reintroduced to Norway like in Sweden and carnivore populations are kept low, hunting would be the main limitation to the population exploding to pig-pocalypse proportions.

Bringing back some of the species we have lost could bring back some biodiversity that we have lost. There will be short term costs, but the long term benefits of preserving biodiversity for future generations is immeasurable. However, I do think the Viking is best left extinct.

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.
