@baryonyx550 they aren't called invasive species for no reason, if you say they drive evolution, your making the false assumption that native species will survive the invasion. To name them invasive species, they must be highly adaptive as well as being a strong competitor, they also reproduce extremely fast. Most of the time, native species do not survive the invasion because they do not have to genetic variability nor the time to evolve quickly enough to form resistance against the invasion.

[commanderben1776]

Very good! Extremely informative. I enjoyed it and we're trying to stop invasives here in Texas too.

[TheAce1082]

hey u know why asia doesn't have invasive species? Cuz they eat that shit. We should just eat all the invasive species that come our way. Seriously, what isn't edible? I'll eat it lol.

[Macrockerify]

do you have a license for catching all those fish

[juglanscinerea]

"we invest so much effort and resources in studying invasive species" because xenophobia and fear of change is where the money's at.

what a waste of energy.

[ashevillecat]

There is no credible evidence to support claims of an "invasive species crisis". These claims are purely speculative, founded on anecdote, biased observation, and an inappropriate projection of the most extreme conditions obtained (massively disturbed oceanic islands). While "pest species" harmful to human health and agricultural productivity do exist, this concept should not be misapplied to natural areas.Zebra Mussels counter eutrophication, improve water quality and Yellow Perch populations.

[baryonyx550]

I've been thinking about this. To be quite honest, "invasive" species are part of what drives evolution and there have been plenty of instances of new species coming into an environment and changing the bio-diversity. Not that I condone an indifferent attitude to the situation, but provided that the overall health of the ecosystem is preserved, maybe the "invasive" species can bring something new to the biodiversity of that ecosystem and in several decades, something might have them figured out.

[fechard]

@baryonyx550 Yes, in fact, not all invasive species are harmful to the invaded ecosystem, some are even benefiting it. Change in a environment is always going. However, because of human activity and globalization, the rate of the spreading of exotic species around the globe has now increased so much that it threatens to homogenize the earth's biota and biodiversity.

[mattjoke88]

@baryonyx550 I agree about your comment on evolution. The rate at which the species are taking over ecosystems is unprecedented.

[juglanscinerea]

@mattjoke88

have you ever heard of the great american interchange?

this is not unprecedented in earth's history AT ALL. Entire biotas of continents have come into contact on extremely short time scales due to rapid sea-level changes in the past.

the only unprecedented aspect is a species (humans in this case) mimicking the effects of a naturally occurring massive species interchange.

It has not caused ecological destruction in the past, there is no reason to think it should do so now.

[applethin]

@baryonyx550 Whatever you have to say about them, the reality is that they're harming our fisheries and that is the main reason these programs must be funded.

[helookslikefamousppl]

@baryonyx550 It's happening because of unnatural causes so the invasive species are more likely to do harm than good.

[baryonyx550]

@helookslikefamousppl please define natural, and when you say harm or good is it in some objective sense or for something in particular. I have no problem with trying to limit damage provided we acknowledge that it ultimately is to keep the planet as we want it to be.

[helookslikefamousppl]

@baryonyx550 When I said unnatural I meant introduced by man. For example during colonial days they introduced Cane Toads to places like the Caribbean and Australia. In Australia there aren't many animals have the ability to eat toads. Many of the local predators that tried preying on them ended up dying from the toad's deadly poison within seconds. In the Caribbean they're a pest and are common as rats even in developed areas.

[baryonyx550]

@helookslikefamousppl What about when the first aerobic microbes emerged? They would have altered the planet's atmosphere (making it have more oxygen) and would have undoubtedly caused a mass extinction of anaerobes in certain areas. Like I said before, I'm not against the idea of being careful about what you let loose in certain areas, but I don't agree with the idea that human caused changes are somehow outside of nature. Any supposed damage we do would be transient in the grand scale.

[ysk8er]

@baryonyx550 I highly agree with your idea sir, however it seems that invasive species for the most part, while they may serve as a catalyst for biodiversity and new ecological relationships, are causing great economic damage as well.

[baryonyx550]

@ysk8er I agree, and that's why we should be careful about what we release, but I don't think we should take the attitude that it's unnatural or that this is about some greater good beyond our own interests.

[MKECBS1]

i found this very useful for one of my presentations on invasive species. thanks for posting

[SudburyBiodiversity]

Another reason to buy local food!

[Omega3chimp]

Put some crocodiles in the great lake Ha!

[crypto457]

America will never learn from Austrailia they'll keep on importing exotic species because they think it's cool to own a tiger or a burmese python

[starshock01]

@crypto457 pffff yeah like australias idea of importing cactus pears was any more intelligent? we dont think its "cool" to own these pets, we just own them like anyone would own a cat or a dog, its people like you that just rationlize what people think

[OffThaDeepEnd]

@starshock01

There's a big difference between owning a Burmese Python and owning a cat. A cat wouldn't really survive in the wild (especially if they've been spayed/neutered), but the Burmese python has no natural enemies in the wild, at least none prevalent enough to keep them in check. Thus far, the Burmese python has overrun parts of Florida and the South. Cats? Feral maybe, but nothing otherwise. You tell me. Also, @crypto457 The Cane Toad fiasco makess you seem hypocritical. Love & Peace.

[starshock01]

@OffThaDeepEnd floridas python problem is because the florida everglades is the same environment as the one they naturally live in, and being cold blooded they dont need to eat every week like cats or dogs, and i dont really think the pythons are nearly as much of threat as some of the other invasive species like zebra mussels...i mean the pythons can be removed and im sure that there are raptors that will gladly eat a passing snake any day ;)

[juglanscinerea]

@OffThaDeepEnd

cats are pretty damn wild in california.

also, it's pretty awesome.

and the introduced wild pigs in CA are pretty awesome as well. they root up the woods for tubers just like the extirpated golden bear once did and in that sense replace a lost ecological function, but people hate them because they are not "native". the same ecological effect is viewed differently based on a distinction of "native" status derived from an arbitrary, fetishized point in ecological history.

[bungcheesio]

American Pussies

[juglanscinerea]

@bungcheesio

right on, bungcheese.

this is a land where cheese is never in short supply, and sap runs freely.

this is a land where humanity runs from nature, sees itself as separate therefrom and has the delusion that it is an all-powerful custodian.

this is a land of judaeo-christian idiots. even those who claim to be beyond the absurdities of christianity persist in the fundamentally christian self-hatred and separation of man from nature. they do so under the guise of "environmentalism".

[CactusFlagg]

@juglanscinerea , not all environmentalists have a superiority complex to nature, quite the opposite. I study Environmenatl Science and im currently doing a Position Paper on Exotic Invasive Species. I think it's wrong for us (humans) to believe that non natives have a negative effect on the environment. All they are doing, is replacing another species importance with it's own, which has been happening for millions of years. I agree with what you said about most believing themselves as seperate.

[juglanscinerea]

@CactusFlagg

good to hear.

i get fiery on the subject. probably backlash against the dogma on the subject i was force-fed in ecology classes in high school and college.

there seems to be a trend in ecology toward a more rational approach. Dov Sax's recent work is a refreshing alternative to Vitousek's alarmism, which has been the mainstream view since the 80's.

still, i don't know if american culture ever learn to leave well enough alone. this country is obsessed with controlling nature.

[soggywallet]

@juglanscinerea You mean 'This country is obsessed with controlling EVERYTHING' America needs to take a step back and CHILL THE FUCK OUT.

[juglanscinerea]

@soggywallet as long as one doesn't try to control how "chilled out" the entire country is, i'm entirely with you.

it will happen, but if one tries to make it happen, one can easily become precisely what one opposes.

i think if we each were to focus inwardly on ourselves and living carefully, observantly and simply, and we were to redirect and deflect the controlling impulses of others, and resist the urge to control others, we might find that things fall into place.

we need that judo shit...

[D12DetroitD12]

i just caught a round goby today in lake erie and its kinda funny to know they have only been here a little less then 20 years...

[phantasystar999]

we have no one to blame but ourselves

[juglanscinerea]

@phantasystar999

boo fucking hoo.

you think everything was in perfect stasis before we moved all these things around?

you think nature works like that?

nature is war, my dear; nature is conquest and invasion, extinction and suffocation, and you are living in a fantasy.

there never was a native eden. there is no less harmony now, and no more chaos, than there ever was.

the only difference is that humans have become soft. and that is why we cry and suffer when we see the chaos before us.

[cochranexyz]

@phantasystar999 For both the spread and preventing the spreading. Humans in our large numbers are the most invasive species of all.

[ebag111s]

kill them all...

[juglanscinerea]

@ebag111s

you're insane.

[ebag111s]

@juglanscinerea LOL

not really :P

[juglanscinerea]

@ebag111s

you very silly, then.

explain to me why we should kill them all (i assume you mean non-native species)

also, presuming they are a generally negative phenomenon (which i personally don't think you have much reason to believe) explain to me how you propose we actually carry out this plan of eradication.

then, look up how many species have been introduced to north america since columbus, and then tell me how many species have gone extinct, and show me the loss of biodiversity.

[ebag111s]

@juglanscinerea All im proposing is the eradication of invasive and harmful species of both plants and animals, for they only put stress on the native species. for example, look at the Asian carp, its extremely fast breeding and growth eliminates the food that is necessary for the native animals.

Not killing the carp will in turn kill several species of fish, which is .... pretty bad

easiest way to kill them is by stopping the fertilization of their eggs, stop the growth of a new generation

[juglanscinerea]

@ebag111s

over 500 exotic fish species have been introduced to the mediterranean sea since the suez canal opened 141 years ago. since then not one single native species of fish has gone extinct.

there have been no extinctions in the Mississippi as a result of carp introduction (nor from any of the many other introduced species). the 5 fish extinctions in the great lakes were due to massive overfishing and pollution, not to non-natives.

[juglanscinerea]

@ebag111s

to eradicate the carp from US waters, we would end up causing far more ecological disruption and than the carp themselves will cause if we just leave things alone, and we'll waste huge amounts of money and energy.

i'm not arguing that the carp can't be a dominant species. there are always dominant species, native or non-native, in any ecosystem. populations are always in flux over time. but there's no reason to believe there will be a mass extinction due to a change in dominance.

[juglanscinerea]

@ebag111s

scientists are realizing that evolution takes place much more rapidly than once supposed, especially in the face of ecological change due to species introductions.

for example, when asian shore crabs were introduced to the east coast 22 years ago, native blue mussels evolved within 5 years to thicken their shells in the presence of the crabs, and no loss of biodiversity has occurred. the crab was quickly integrated into the "native" ecosystem and biodiversity has actually increased.

[PheonixHeart1974]

I reality, none are foreign because they are all live on planet earth. The people who wrote H.R. 669 are knee-jerk wacko's. It is NOT the gov. job to control these few & far between instances. The bill absolutely violates the rights of the people own ANY type of pet they want. NO on H.R. 669

[RenatoandEric]

vote NO to hr669!

[bgbreakdown]

Contact your congress person and urge them to vote no on HR 669.

[wobinga7]

we need to do more about invasive species
