Interesting/Little Known introduced populations

Here's one I found out about yesterday, Indian civets in Madagascar.

 

Now this is very interesting indeed, I'd not heard of these either. A quick google reveals multiple references to them being introduced (including a webpage with a trail camera photograph of one taken in Madagascar), but no information on range, population or when they first arrived. Anyone have more information on these?

 

Saw in mentioned on this website:

Article about invasive species :

Rhesus monkeys, Silver Spring - Florida :

While not directly introduced by humans, I think we could mention Golden jackal as an example of a species that currently increases its range explosivelly and it probably is indirectly caused by humans. By intensive agriculture, deforestation and eradication of wolves in large part of Europe, we have prepaired an ideal living niche for this species. And it decided to make use of it.

 

I think there has been confusion with Asian Swamp Eels (which like Electrics aren't eels either).

 

My suspicion was aroused by the the same word useage!

 

Bird of Paradise on Little Tobago ( think they have been discused already before on ZooChat ) :

The beginning of a population of Glossy ibisses in Ireland ?

While interesting, it don't match with the purpose of this thread, that is about introduced species

 

Doesn't it?

According to the article: "One theory as to why they are being spotted more often in Northern European countries is due to climate change - drier conditions in France, Spain and Portugal are pushing them northwards."

The overwhelming majority of experts agree climate change is anthropogenic. If we define introduced species as populations outside their native range as a result of human activity, you could argue these birds count (or may in the future).

 

Aha, but you could make the same argument for any introduced species. Island endemics, for example: the main reason why terrestrial species naturally expand their range to oceanic islands is translocation. So, what's the difference between vegetation rafts, hitchhiking parasites, etc. and humans releasing rats, goats, and rabbits on the Galapagos?

The key point, I think, is the impact new arrivals have on existing communities not adapted to them. From that perspective, it doesn't matter whether the invader arrived on a cargo ship or warmer currents.

 

Are they realy wild birds or maybe escapeds ? Glossy ibisses are kept in good numbers ( at least at mainland European collections ( both public and privat ) and the birds were observed first afther a heavy storm which could have destroyed - next to a lot of other things - also aviaries in which - for example - Glossy ibisses were kept. Would be intresting if ( some of ) the birds have rings....
