Are bullrushes invasive?

>>2258251

No idea where my post proving you wrong went, but oh well.

>>2258360
that's a fucking stupid statement
think about it and rephrase it

we had/have our native crayfish species.

Well several of our 'native' species have North American origins. They crossed the land bridge.
So are our ecosystems fucked up?

Personally think the American mink is a damn shame, because we have our own European mink. Guess the American is fitter. Otters seems to outcompete them a bit.

American beaver seems to outcompete the European beaver in Finland as well.

As for the crayfish, I personally prefer to have several non-native crayfishes than our native crayfish which can barely handle pollution and disease. Besides Sweden is still full of them (Noble crayfish). Though some of the North-American crayfish can cross land and colonize waters which amphibians use to breed, and this does fuck up the amphibians.

Similar stuff with our red squirrel, it is clearly adapted to conifer species, while your grey squirrel can digest the acid of acorns much better and is clearly a deciduous forest type of squirrel. Funny the grey squirrel can't handle the pine marten as well as the red squirrel because it is fat tho.

Also, many of the trees introduced from North-America to Europe used to have relatives here in Europe until that damn Ice Age killed off most of them. But really, foreign plants are usually a bigger ecological problem in my opinion (compared to insects, mammals and so on) since they do not have any or many insects feeding on them (which in turn support species of birds and so on).

But the black cherry (Prunus serotina) does now have more insects feeding, living on them, than our native bird cherry (Prunus paddus). But this is only possible because they are closely related. I can show you the study of this if you are interested.

Something like the introduced black locust has almost no invertebrates supporting it. Same with red oak (Quercus rubra), which can also aggressively seed.

Personally think we don't really got a fuck-up, just a mixed bag.

Louisiana crawfish are invasive to Europe

>>2258579
They are the ones causing the trouble with amphibians namely in Spain.
We have another one which causes less trouble, but crayfish plague does harm the noble crayfish.

There's another North-American crayfish that also walks on land however.

It seems every generation has an invasive species which kills trees
My parents had dutch elm disease, now we have EAB

>>2258756

Reticulated pythons.

They even eat motherfuckin gators!

>>2259175
Beech trees are diseased near me but the fungus only attacks mature trees over 20cm diameter

>>2259175
>My parents had dutch elm disease
You had trees as your parents? Interesting, how did that work out for you?

>>2259397
I just read about this and it's Burmese and reticulated pythons which became an invasive species from people releasing pet snakes

Wouldn't this cause a genetic bottle neck? Wouldn't there need to have been dozens or more original specimens released to ensure genetic diversity?

At what point could the snakes become so inbred that they're all diseased, or does this not happen to reptiles?

>>2258680
I thought everyone loved our mosquito fish other than the Aussies

>>2259403
The fruit doesn't fall far from the tree.

You only need to frequent this board regulalrly to learn quite how many retarded, irresponsible, immature and downright anatagonistic assholes own various non-native animals and are happy to release ones they don't want for whatever reason into the wild.

The original stock of these snakes probably runs into the tens or hundreds - plenty enough for genetic diversity to be sufficient, and they seem to be thriving in Florida.

I let my pet zebra mussels go in lake Ontario about 30 years ago
Is that bad?

Good.

i actually have a relevant true story like this
>be my granddad
>be in southern oklahoma
>be kid, probably 10 years old
>have a spare dollar
>see an ad in a magazine for 10 green anoles for $1
>want them
>order them
>about a day later they arrive in a tube in the mail
>over the course of the week lose them all in wilderness
>they breed and begin to spread
and thats the story of how my granddad introduced anoles to about 9-10 different counties in southern ok

>>2260119
Are they a common invasive species?

>>2260263
im not entirely sure i just know that he introduced them to an area which wasnt apart of their natural habitat
