Hi everyone,

I first came across artificial selection at a young age through my love of dogs and my constant questions on why that puppy had spots, or long hair, or how come it was a guide dog etc. In highschool I was introduced to genetic inheritance along with evolution which sparked my interest in science, in particular Zoology, Ecology & Conservation. Now here I am as an undergrad and I hope to introduce you to the topic I find most riveting: Domestication. I shall endeavor to cover all areas, from agriculture and livestock species selected for human benefit to species bred purely for aesthetic enjoyment such as ornamental plants and pets, along with any scientific processes or ethical debates that arise along the way.

enjoy!

‘Domestication is an evolutionary process of species divergence in which morphological and physiological changes result from the cultivation/tending of plant or animal species by a mutualistic partner, most prominently humans.’ (Purugganan & Fuller, 2010)

Domestication As A Form Of Conservation??





An interesting piece for the enjoyment of Tasmin :) 

Australia has such unique fauna with great diversity as shown by native mammals such as whale that patrol the coastline to microbats weighing no more than a few grams. However many people are unfamiliar with their native fauna, such as quolls, quokkas and antechinuses. This unfamiliarity and anonymity of species can be due to our urbanisation where cities are harsh in terms of food sources, shelter and predation/competition from domestic cats and dogs. Many of our Australian mammals aren’t spectacular and go un-noticed in that they are particularly small, in some cases less than 100 grams, some even being nocturnal.

An article by Paul Hopwood (1996) puts forth the idea of allowing the keeping of Australian natives as pets. Currently government policy across all states prevents the keeping of endangered species, with some states enforcing a blanket ban irrespective of species status. Hopwood’s perspective is that there is great conservation value in maintaining colonies of endangered mammal species – provided that they make good pets. Now, two obvious sides emerge: potential detrimental outcomes for species survival in a conservation sense, morally wrong to restrict a wild animal; or positives in that native species are less environmentally damaging and the set-up of commercially viable pet industry with regards to breeding colonies can buffer the endangered species from extinction.
Focusing on practicality, certain characteristics such as easy to handle, readily available, affordable food supply, housing requirements and robustness are required for an Australian native mammal to be suitable. Another major issue is zoonotic diseases carried by native mammals; however in most situations preventative medical services are available.
Mitchell’s Hopping Mouse
Mitchells Hopping Mouse (Notomys mitchelli)
One animal species that would be suitable is Notomys. They will not kill your local birds and lizards, they eat little, have non-smelly poo, can be kept in a mouse tank and have a temperament suitable for handling. Best of all, if you were to keep Notomys mitchelli you would be doing conservation in New South Wales a service as this hopping mouse has been extinct from this State for over 50 years.

This point of view raises many questions, especially on intent behind the domestication of a species. Is it possible that future conservation plans may incorporate domestication as a last resort for survival of a species? It is a definite possibility for many endangered native Australian rodents whose numbers are dwindling.

  1. A very interesting proposal indeed! While rodents are remarkably adorable (yes, I’m biased), I would have to argue that not all rodents make good pets! Notomys (while being stunning) are nocturnal, so if you want to stay up all night, then perhaps that’s okay  What about the potential implications for maintaining a species in captivity when it’s primary habitat has been destroyed? Surely it would be better to conserve the habitat and not focus on particular species? A lot of questions to think about!

  2. This is happening with the Oenpelli python right now (http://www.theaustralian.com.au/news/features/to-breed-or-not-to-breed-game-of-snakes-and-ladders/story-e6frg6z6-1226630304503#). A handful of these rare snakes have been collected from the wild (with a permit from the NT government) with the intention of breeding for sale to private keepers. It has also been done with the rough-scaled python. There's no doubt there's problems with the idea. I have questions about whether or not such a small founding population is genetically viable in the long run. I also think anything that isn't cute and furry (or scaly for the herp enthusiasts) could miss out. However, I feel all options must be considered. I agree with Tasmin that it's better to conserve habitat, but many other people with a development bent don't see it that way. Bringing a species into the pet trade might be preferable to letting it go extinct. And I wouldn't mind a quoll. :-)
