[@theotheseaeagle]

Exactly only problem is that feral hogs in America breed much faster than wild boar, meaning you’d need a lot more predators to manage them than would be needed naturally. Though predators do create an ecologically of fear and most of the issues arising from feral hogs is the fact they stay in certain areas for too long and cause damage instead of moving around to different areas frequently to avoid predation as they would do naturally

Another good example was the inadvertent introduction of the horse into North America, their original home. They went feral and by the 19th century there were millions all across the continent.

[@feiryfella]

They evolved there and only disappeared very, very recently. The issue is the lack of natural predators such as wolves and puma.

[@adeptgirl3454]

There's a similar story with camels. First evolved in North America, migrated to Eurasia and went extinct in North America, reintroduced by accident in west Texas following a failed attempt to use them for military desert transport, and weirdly successful in the land of their ancestors.

One of the biggest sources of non-native fish in Florida are the massive rainstorms. There are many small to medium scale fish farms with outdoor ponds for raising aquarium fish, pond fish, etc. Some are in-ground, some above ground, but often only shade cloth is used for cover. These ponds overflow into the vast network of open air drainage ditches and retention ponds during flooding rains. It is common for several inches of rain to fall in a short time, and wind gusts of 65 MPH are not unusual in any thunderstorm. You can net a shocking variety of fish from puddles and ditches after a rain, many are breeding in quantity in the wild. Platys, Mollies and such are ubiquitous, but everything from freshwater Pufferfish to Koi are common. While released pets are a big problem, 1992's Hurricane Andrew did release vast numbers of birds, reptiles and snakes from the dozens of import facilities that were heavily damaged. Fortunately, there weren't enough of the most dangerous imported snakes to form breeding populations. One African Green Mamba was found soon after the storm.

As always, one of the biggest issues is a lack of native predators to control invasive herbivores, especially in places like Australia (bring back Komodo dragons, for feck's sake).

Not necessarily viruses, given their unpredictability, but definitely vectors that might cause infertility to limit further growth of invasives.

The only reason the non-native birds had such negative impacts on native bird species is because they are resistant carriers for avian malaria. Many of the native bird species directly defend territory against non-native species.

[@b.a.erlebacher1139]

The story I read was that there were originally no mosquitoes in Hawaii. Some seabirds carried malaria, but in the absence of mosquitoes it couldn't spread to the native birds. In the late 19th century a ship from South America went to fill its water barrels from a coastal stream. They didn't dump all the old water into the sea, and some was dumped into the stream. It contained mosquito larvae, and mosquitoes rapidly became established. They carried malaria from seabirds to the native birds which had no resistance, and most native birds became extinct, except for those that lived at an altitude too high and cold for the mosquitoes. I can't recall the details, but the name of the ship and date the mosquitoes were introduced are known.

You can argue that dung beetles have helped the ecosystem by taking care of dung from non native herbivores the native dung beetles couldn't handle.

[@lordgrunwalder1607]

The problem is that the more species goes extinct even the worse potential change becomes benefical to a enviorment. Like cattles saving condors from extinction as no megafauna left on south america. But this still doesnt mean cows are benefical or would be this benefical if south america wasnt this messed up. Because they arent the same animal as extinct animals. Proxies only work to a certain deggree For example most people forget how australia suffers from hooves. Animals like deer, cattle and pigs make the ground harder as they walk on it and make plants adapted on previous soft footed fauna suffer. Even such small changes matter in term of ecosystems!

Invasive species are not a new phenomenom either. I'm rather certain that Dandelions are invasive in much of what is now considered their native range. They were planted for food in the ancient world(see: Rome), they probably originate in southern Europe, and are invasive pretty much everywhere else, but are not considered so, because they're not harmful in most ecosystems.

[@creatureking-theoriginal1068]

i would have never thought that invasive species could help yet here we are

[@alveolate]

i think it requires a LOT of study and very careful testing to properly introduce a non-native species and have it bring only benefits to an ecosystem. there are so many ways that an introduced species could throw things out of balance leading to a trophic cascade of some sort and a collapse of the food chain. we have too many stories of failed introductions of species, which had almost always started out with a good intention, sometimes even with quite a bit of study and testing but some unexpected factor shows up and it all implodes. invasive species that turned out to be beneficial overall are probably a very rare exception. they still may bring negatives to the ecosystem, even if the net effect looks positive. the biggest issue is that these introductions are mostly irreversible.

[@korayven9255]

Invasive simply means non-native species that were introduced into an ecosystem and were well-suited enough to their new environment to survive and breed. There's nothing that really requires invasive species to have a negative impact on the broader system and it's actually quite likely that most invasive species in history simply quietly integrated into their new environment without any fanfare before eventually evolving into nativity.

[@chatterbox5508]

@@korayven9255what you are talking about is just a non-native species or introduced species. By definition, an invasive species (at least in regard to plants) is a non-native species that negatively impacts the native ecosystem/native-species.

Unless you are very young, this is concerning.

[@korayven9255]

@@chatterbox5508 No, there are exactly two requirements to define a species as invasive: they must be non-native and they must be highly adapted for their new environment. That's it. The latter can very easily create negative consequences if they are _too_ highly adapted for their new environment that they heavily outcompete native species, but adaptability and detrimentality are *not* intertwined and you can absolutely have invasive species that fill an otherwise empty ecological niche in an area. They don't cause problems for the native species but they are no less invasive to their new environment.

[@thomashaapalainen4108]

The snail kite is also a great example of evolution at work. The snail kites today have a different beak structure than their ancestors did just 100 years ago. Selective pressures have favored a larger hooked beak to more effectively prey upon the larger invasive apple snails than their ancestors who exclusively ate the smaller native variety of apple snails.

[@goatsandroses4258]

Invasives can certainly be a problem..to wit the wild hogs here in Texas that we battle constantly. But ecosystems and species are NOT stable or static. It's very true that humans have introduced huge numbers of new species, but species slowly migrate or are brought by storms, etc. anyway, just as the weather and terrain themselves change over time. Species naturally go extinct, and other species arise. We can try to be cautious so as not to have a sudden negative impact, but we cannot stop the world from changing; it's impossible, and denies the very nature of Nature itself.

I know right? People have this annoying mindset that everything in must life especially ecosystems must remain the same forever just because they don't want to get used to something new and unfamiliar. It's an addiction, so much so that when there are positive affects to some introduce species many people will resort to deliberately spread false information like "ALL introduced species are evil monsters that take resources and poison bloodlines and need to be killed no matter what and anyone who tries to prove that there are positive impacts of any kind should be treated like an idiot because everything should always be the same just because we don't like change!!!!" Like when you hear the way they talk, they sound like cultists which is very stupid. Fourthly, more and more scientists are starting relies that not all introduced species have bad impacts and even ones that do have negative impacts can also bring positive affects in ecosystems because they know that nothing in life ever stays the same forever no matter what humans do ( not even ecosystems ) because humans can't control EVERYTHING. Non native species arrive in new ecosystems all time with or without human help. It's been happening before humans and will continue to happen when humans are gone. Besides lets face it, if mother nature could talk I'm pretty sure she wouldn't care if a species is native or non native because again this sort of thing has always been happening and if good and evil don't exist in nature than native, non native and invasive don't exist ether. They're just organisms trying to stay alive like everything else.

Because non natives were brought to a new area where the ecosystem doesn’t have any barriers toward it no defenses no controls and it can just go crazy despite human interaction. Many animals and plants can adapt but niche species like let’s say trees that require a mature forest habitat typically perish. While ones that survive in the clearings and edges of a forest and pioneer plants that can grow in higher light levels can recolonize after a forest is logged down. Human activity selects for generalist species that can quickly rebound after a disturbance.

[@greasher926]

Probably the same thing that happened in Argentina. From my understanding trees in the southern hemisphere don’t coppice, meaning they don’t grow suckers/new trunks from the root when chopped down. So when a beaver is introduced the beavers just deforest the place, and forest never regenerates. It is unable to keep up with the amount a beaver consumes.

Those do eat plants, but they are not sell ofthen in the acuarium trade becouse THEY EAT PLANTS.

The same process will occur with the human introduced species.

[@JoshTrager-j9g]

Well, your first point is correct. And it truly breaks my heart just how much we humans have ravaged and destroyed a once-pristine island paradise, we basically ruined Hawaii. 😢 (And the natives aren't any better either, they pushed many species to extinction too. They're just as guilty.) That all said, I'm not sure you understand what the term invasive species means. You see, if a group of animals reaches a destination through chance or circumstance, then they're not invasive. Invasive species literally didn't exist until we humans evolved. We CREATED the concept of invasive species. And it fits too, since we created more of what we humans are-the worst of all invasive species.

A wave of extinctions followed, especially on the formally island continent of South America. But both continents ended up more biodiverse that they were previously.

With the more insular areas from Australia to Hawaii taking the heaviest hits. We need to be careful about what we do. We need to be careful about what we move where. But we also need careful about what we try and push out. Ecosystems, especially islands, are fragile and can be disrupted by a new player. But at the same time ecosystems self-organize.

People need to get over their irrational hatred for introduced species.

And not every introduced species is harmful, there are many species that occupy niches that were unoccupied before or that can even benefit the local ecosystem. Species spreading to new areas is part of nature, think about how much of central europe was covered by glaciers and tundra landscape 20 000 years ago, and pretty much everything that lives here now has spread here after the ice age. There was also a lot of species exchange between asia and north america when the bering strait was dry land during the last ice age. Humanity is just accelerating it a bit.

@@JoshTrager-j9g They used to gather in such large numbers in one place that they would bring down entire tree limbs from too much weight all at once & let light in through the canopy.

There’s feral donkeys in Arizona as well.

[@DS.proudkiwi]

Interesting story I spent time growing up on the quarantine island in NZ where they were first brought and let go wild in NZ....they pretty awesome animals

[@TsukiCove]

yep one of the clips of feral donkeys near the start is in Arizona :)

Do a video on africas extinct mammals like cats canids ungulates elephants etc like ones that went extinct

Wish catfish plecostumus and water hyacinth do the same to my ecosystem, but they became plague to our ecosystem

Peak content.

[@kelvinchua4084]

As aquarium species are released into the wild will affect biodiversity and damage the native wildlife. We need to pass the message to the world so the importance of conservation to our nature native to family and friends.

[@aaaydenwetsell]

in the makauwahi cave reserve in kauai hawaii, there are around 17 rescued african sulcata tortoises living there that are being used as pleistocene rewilding substitutes for the extinct turtle jawed kauai goose, and the kauai mole duck that used to live there before people and feral species arrived on the island.

[@andrewst9797]

Many "original, native" islanders were terrible invasive species. For example the Maoris of New Zealand, the Australian Aborigines, the Indonesian settlers in Madagascar and many more.

[@hypanusamericanus9058]

It’s not really like every other people group in every other region of the world is exempt from that assumption.

[@mrprotheroe4981]

Have there been any invasive species that got annihilated by the native species?

[@DS.proudkiwi]

I'll second that

[@eljanrimsa5843]

Most introduced species get annihilated by the native species, but you don't call the annihilated ones "invasive".

[@CheatsythePimp2]

I’m surprised you didn’t reference the tortoises in Hawaii?

[@JoshTrager-j9g]

Well, they had to bring those in because the native Hawaiians slaughtered all the native creatures there, like the giant flightless ducks that once lived on Hawaii.

I bet the snail kite gets ribbed at the raptor family reunions .

[@JoshTrager-j9g]

Personally, I'd say invasive species are ALWAYS bad, and introducing animal/plant species is ALMOST always bad.

[@brianboye8025]

I want to see Lake Baikal ring seals living in the Great Lakes in America. There are so many non-native species there already. Maybe some small species of whales could live there as well. Whales were there maybe 10,000 years ago.

[@JoshTrager-j9g]

That's.......a really, REALLY bad idea.

[@comradecat3678]

Native Hawaiians in the 1200s (possibly 800AD) destroyed the original untouched Hawaiian Ecology (there were even crazier birds)

[@JoshTrager-j9g]

As a bird lover, it truly breaks my heart to know how many wondrous birds perished because of them. 😢

[@comradecat3678]

@user-rs8ky8hv6s New Zealand was the exact same story the Maori people didn't get there till around 1000AD there was a giant 12 foot emu type bird (but friendly) it died out like only 20 years before Europeans got there

[@JoshTrager-j9g]

@@comradecat3678 Oh I know ALL about New Zealand, trust me. It's the same heartbreaking story there too. 😢 Even now, I'll never forgive the Maori for what their ancestors did to the Moas. It was a ruthless, wholesale slaughter.

[@comradecat3678]

@user-rs8ky8hv6s kinda weird not to have some reverence for something so big (and non threatening) most places elephants have lived they had God like status horses same deal, even the Buffalo were respected by the natives quite a bit

This video is very unbalanced, the alleged “beneficial effects” are anecdotal and debatable compared to the continent-wide biodiversity crisis induced by alien species. -For birds in Hawaii the extinctions are overwhelmingly due to invasive species (predators, birds, parasites, plants, etc.). Keep in mind for instance that invasive plants directly cause habitat loss or prevent habitat regeneration. -For the dung beetles in Australia you say: “because they feed on dung that most native species can’t process, they are not competing with them” this statement is completely wrong! The question is whether the introduced beetles can and do process the native species food sources. Pokhrel MR, Cairns SC, Andrew NR. 2020.
