Dr. Nelson is a really good guest for this show, I think because she brings enough energy and assertiveness to match Hank. Hank talks a lot and I've seen him sort of talk over other guests, but Dr. Nelson is fantastic at holding space.
My cat brought in a wood pigeon once. He was so proud! You could hear him purring from the next room. And he was most upset when I released the mostly unharmed pigeon into the wild again.
Yes! My cats have occasionally caught a bird, but they usually are gentle enough that I can rescue the bird. They caught a baby sparrow once, at the age when it was just starting to fly, I rescued it, fed it for a few days, then released it - and its parents RECLAIMED it! They had apparently been waiting around for a few days while I fed the little mite out in the yard, and once it was free, they both flew down and encouraged it to fly into a tree. Dogs, on the other hand... My dog was a whiz at catching flies in the house. We thought it was wonderful - until we realized that she was using the same technique to chomp robins in the yard... Imo dogs do as much if not more damage than cats, at killing off bird populations.
@@WWZenaDo I'm sorry, but although he has on occasion brought in live birds, he has also killed quite a few of them. He tends to swallow them whole, though, so all I find is a clutch of feathers in the morning.
@@WWZenaDo Sparrows, wrens, red robins.Maybe not whole - I think he bites the head of separately. For a long time he didn't eat them, but then he was lost for five weeks and I think he learned that there was food on them.
I just completed a research project about the use of native plant allelochemicals in suppression in invaders that disperse through wind. Found that the reversal of the “novel weapons hypothesis” has the potential to be helpful in preventing spread of some invaders from spreading.
Good subject, but a couple of points: 1) Not all herbicides keep seeds from germinating for long periods of time. Also, there's seldom a need to soak the ground with the defoliant type at all, so it's a non-issue. They should be avoided when possible, but if the choice is loss of species due to habitat spoiling (monoculture) and a temporary set-back with recovery, it's pretty obvious which is the better choice. 2) One of the means of control we often use is planting varietals of an invasive species which have a genetic dominant that causes it to produce fewer seeds. Lantana is an excellent example of this - lantana montevidensis can pollinate the escaped wild variety and cause it to produce fewer seeds for several generations. Effectiveness of this ranges from stopgap to eventual eradication in some invasives. 3) Animal controls work great in some areas, but have already proven a fail in many wildlands, where the worst of the ecological disasters exist. Chinese tallow tree (Triadica sebifera) has no known pests and no other means of control than herbicides. Fairly large areas of the Florida Everglades are sprayed annually as the tree has established monoculture in some areas. While I appreciate Dr. Nelson's work and believe that a multi-pronged approach *including* animal based controls is effective when applicable, I wish this had been a more comprehensive discussion.
Guests have brought in physical items for discussion in previous episodes. In this talk show format, I think that would promote more back and forth between hank and guest(s). I'd prefer that rather than inserted media.
Two topics I’ve dealt with as a wetland naturalist! One of the big issues the groups I’ve worked with in invasive weed eradication is the issue of removing invasive plants just to have them return. In species that produce clumps or have deep taproots or long runners/stolons, we had real issues with soil disturbance upon removal making for a prime seed bed for more prolific seed dispersers. What worked in some cases (when feasible based on species and accessibility) was to cut down the offending clump and paint glyphosate - with no surfactants - onto the wounded plant. This killed the invasive without disturbing the soil or making the surrounding area a kill zone for plugs we planted around the dying weed. Really labor intensive and particular to perennial species, though. It’s not like this method can be used on Medusahead Grass (though controlled burns help against that one). In California salt marshes, we are dealing with a weird invasive dilemma: a super vigorous hybrid between a non-native cordgrass and our native one has started dramatically altering wetland shape and structure to the reduction of how many species the wetlands can support. However, there are a couple endangered/threatened species of rails that live in the cordgrass and are doing well in the areas the new hybrid is taking over, since it grows denser than predators like herons are used to penetrating into. There are a bunch of double-brood bird species, though the actual studies on them are generally centered around species that routinely nest near humans or in human-managed nest boxes (which can be effectively monitored). There appears to be a correlation to successful multi-brood behavior in Eastern Bluebirds and latitude, with birds on the east coast of North America in the north having larger clutch sizes and fewer broods compared to smaller clutch size and more broods in the south. On the west coast, California Quail will rear multiple broods with previous broods remaining in a flock with the new chicks. Marsh Wrens will try to attract a female by building many framework nests that one will be selected from and finished by the female; sometimes another female can select another nest in the same male’s territory and two broods will be raised at once, plus wrens have been implicated in returning after successfully fledging young and raising another brood.
They return because they are ecologically important and because nature *wants* them there. To believe anything else is just that- "belief". Invasion ecology is much closer to a nationalist religion than a science.
Kudzu is rampant in the southeast United States. It's a climbing vine that grows fast and covers everthing with broad leaves so native plants don't get any sun.
That's a bit of an exaggeration. Kudzu is invasive, but not nearly as bad as it's made out to be. www.smithsonianmag.com/science-nature/true-story-kudzu-vine-ate-south-180956325/
This is false. No actual evidence to back up the claims of environmental harm caused by this or any other so-called "invasive" plant. See the work of Mark Davis, David Theodoropoulos, David Frank, Tao Orion and so many others trying to stem this tide of almost religious fervor around the further destruction of ecosystems in the name of a pseudoscience that has become more of a religion and cult of personality over time.
7:00 Strawberries are connected through ABOVE ground stems (called stolons, commonly known as runners) the below ground ones she's talking about are called rhizomes. Also, sheep and goats FTW! (I've never eaten goat, but I like (some breeds of) goats milk, and I love to eat sheep)

I had a white dove named Angel that was a school pet in 4th grade. The teacher gave her to me when she moved away at the end of the following school year. She looked a lot like the white one showed here, but not that thin. Her beak was a slightly darker pink too. She laid her first eggs starting when I took her home for spring break, and laid about 2 more every 6 weeks or so for about 8 more years. She then lived another decade after the avian equivalent of menopause. For the last few years she was too weak to fly much. We once left her cage wide open for a whole year without noticing it as she never tried to leave.
First kind of episode of this format I watched, really enjoyed it. The different topics were interesting and I have a general fondness towards birds :)
Zack Lindner there is a whole playlist of scishow talk shows that are very good and Animal wonders Montana has a playlist about their birds including Willow and kia's stories. I highly recommend checking them out.
This conservation biologist wishes you would leave it there and learn about the destruction caused by efforts to remove so-called "invasives", otherwise known as dispersing species... a process that is integral to the evolution and adaptation of ecosystems.
Could you do a video on the relationships between Dingoes, hoping mice and desert ecosystems? There’s some really interesting research coming out of the Strezlecki Desert
Pigeons may be an invasive species, but they provide a heck of a lot of meat for hawks, owls, foxes, and other native species. I suspect that these domesticated pigeons have helped fill the prey gap left by the extinction of the passenger pigeons.
Very informative discussion. (For those interested in these subjects, I have an ‘Invasive Plants’ playlist and two ‘Reforestation and Ecosystems Restoration‘ playlists on my channel.)
pollinate out the traits of the leafy spurge. Selectively breed out the plants undesirable traits, use crisper and counter infest a reigion to change the plant.
Purple Heart plants (Setcreasea pallida) is another plant which is absolutely gorgeous but dear lord is it a plague in certain areas. In very hot, humid climates that plant is damn near unstoppable.
@@pauljackson3491 Supposedly, contaminated flax seed, brought by Russian immigrants to South Dakota in 1873, is thought to be the source of Russian thistle invasion.
How do you feel about invasive species replacing species that humans have driven to extinction? For instance, the hippos in Columbia filling the niche left by the disappearance of megafauna in South America? Horses in North America?
Why a taco stand though? Aren't there breeds of sheep and goats that are purely raised for their wool? It seems to me that would be even better - you wouldn't lose your "weed control experts" at slaughtering time, you'd just shear them and have that little bit of extra income. Or do the hair-raising sorts of ruminants have different nutritional needs compared to those raised for meat? (Yes, pun intended of course.) Both species also produce useful milk, potentially. It seems like there's a LOT more that you could get out of a herd of goats than just tacos, is all I'm sayin' here.
Goats are awesome. They even eat poison ivy and have delicious milk with little lactose and a lot of protein. I should know I used to have a milking goat.
I used to have a white dove (the same sort as the one in this video) and a grey-split-lutino cockatiel. They were both female. They both tried mate with the other fairly often, but neither of them wanted to be on the bottom.

Squeaky Deeds Done Soap Clean It is an active field, but plagued with the issues inherent in the grant-competition system in the US. The much greater growth many cite is in the fields of engineering, programming, manufacturing, and implementation management for sustainable technologies. These work hand-in-hand with environmental scientists, natural resource conservation management, and watershed monitoring and assessment auditors/researchers, but many development projects can draw from the same pool of these professionals.
This is a call for help, I'm from Venezuela and my people are dying. The regime that is controlling the country is actively trying to have us on the brink of famine. Most Venezuelans don't know how to speak English so I'm making this sort of message in a bottle to see if I can at least reach some people that will care. Having people know the horrors that we are living should be enough to give us at least a bit of hope. Googling Venezuelan crisis or something should shed some light on this situation.
@@mortuos557 I am so thankful for your reply. The biggest thing I'm afraid of is of people dismissing the situation of my country, so awareness and proper information is the thing we need the most. If you can inform friends or other people that would be a huge help. I've seen people give the Venezuelan crisis a political or ideologistic tone, but this quickly falls apart with a bit of research, no ideology should bring so much misery.

I understand that host has to add comments or ask additional questions to the guest in order to manipulate the topic a bit. But I couldn't stop feeling that Hank was in inebriated mind. The comments or questions he brought up were a bit arrogant and unattractive. Felt sorry for Dr. Nelson for his behavior. Though the topic was interesting, thank you for inviting such a specialist.
Ok thats cool . i never knew the ringneck and Eurasian were different bc they seem similar. Also their calls!! Usually i hear the ringneck call and few times Eurasian but I NEVER KNEW IT WAS EURASIA!! I always thought it was a confused dove singing lol
Every time I watch one of these i think, "wow, Montana is so amazing!" Why is it that in the global zeitgeist or whatever, the US only seems to be made up of New York and California and sometimes Hawaii?
Hey, we have Texas too! Actually go back to forgetting we exist our stories are rarely good. Actual answer: It's because New York and California are the media centers of the U.S. and some of the biggest media exporters of the entire world. Montana is a beautiful state and one I wouldn't mind living in but as far as I'm aware it isn't particularly notable for any reasons. I believe most anywhere in a first world country should have areas with people interested in science and animals and such (try local animal shelters and universities if you want to join one, volunteering can help). No idea why Hawaii is in this list? I mean it's well known but I can't recall any significant events that have happened since the volcano blew up a while ago and I can't even remember when. It wasn't all that prevalent in American media.
There's a pair of these doves in the tree in front of my windows. Years ago, there was a white one too. (that's in Vienna) [note: how exactly does she write "eksetera"? *gnnnn*]
lol no, mars only has 1% of the atmosphere of earth, and winters that average -40C°. maybe some arctic lichen can be more of help, but definetly not spurge. maybe on some later stages of terraformation though.
How far from a house is a cat considered an invasive species? I've been hiking miles away from any home and have seen cats. Some with dead birds in their mouth.
They're invasive whenever they roam free outside. They kill stuff just for fun and damage ecosystems everywhere people live. On top of that people feed them and protect them from disease and extreme weather. That means there's not much damaging the population, which leads to many native animal populations continuously declining. They also spread toxoplasmosis, which is a whole other thing and a huge reason to keep your cats inside. Don't get me wrong, cats are great adorable creatures, but their place isn't outside killing birds.
@@bratatouille oh I know all this. We tend to rate animals by how cute they are. In my state, it is illegal to dispatch farrel cats, although I know plenty of farmers that have to every year in their barns. It's sad, but it is a problem that we created :-(

Hank! Surley you are aware that Florida is a "melting pot" of the melting pot of the melt..... yeah, mass amalgamation can be conducive to the atrocity of various levels and patches (?) of monocultures- the opposite of beloved biodiversity. So folks both unknowingly and deliberately bring bits of their HOMELAND largely unaware of long-term impacts like hydrology, fire ecology etc..... btw, prescribed burns are a great tool in slowing infestations so enjoy some SMOKE all humans - don't cry about it.

not that good insects are nurmeous enough thanks to the competitive nature of human neighbors and their chemically-dependant lawn obsessions.

It may depend on your location. Here in Oregon there are several new openings every week. I'm in college, and have been getting environmental science job notifications weekly from Indeed for months to keep me motivated!

It is an active field, but plagued with the issues inherent in the grant-competition system in the US. The much greater growth many cite is in the fields of engineering, programming, manufacturing, and implementation management for sustainable technologies. These work hand-in-hand with environmental scientists, natural resource conservation management, and watershed monitoring and assessment auditors/researchers, but many development projects can draw from the same pool of these professionals.
Beef, especially grain fed beef, tastes a whole lot better than mutton.
Lesbian doves?
Yes.
Or just friends. Hard to say either way. You'd have to ask them, and I don't think anyone speaks dove (except maybe Jessie :D )
IKR? nature giving the finger to homophobes lol
LESBIGEONS
What about training mice/rats to find the seeds kind of like search and rescue dogs.
Training is hella hella expensive, genetic engineering might be better
This needs to be live!!!! LIVE QUESTIONS :D

This is a call for help, I'm from Venezuela and my people are dying. The regime that is controlling the country is actively trying to have us on the brink of famine. Most Venezuelans don't know how to speak English so I'm making this sort of message in a bottle to see if I can at least reach some people that will care. Having people know the horrors that we are living should be enough to give us at least a bit of hope. Googling Venezuelan crisis or something should shed some light on this situation.
@@mortuos557 I am so thankful for your reply. The biggest thing I'm afraid of is of people dismissing the situation of my country, so awareness and proper information is the thing we need the most. If you can inform friends or other people that would be a huge help. I've seen people give the Venezuelan crisis a political or ideologistic tone, but this quickly falls apart with a bit of research, no ideology should bring so much misery.
Well this is now on my radar. Time for some research.
The west coast of western Washington? As opposed to all of those other coasts that Washington has? And that west coast that it has on its east and south?
I like the west coast on eastern washington...
Lol he said muffs instead of mutton chops lol. Hair near the lower mouth lol
Hank Green is both intellectual and carnal!
Dinosaurs on Scishow talk show!
Can we use this in space research since they want to act like they are all big and resilient?
What about the sheep poop with the invasive plants seeds?
How are sheep dumb for eating food that they are used to?
Sheep will be waiting for hank.....lol
I wish someone could come up with a solution to poison ivy.. I've grown up in Ottawa Ontario and have seen it spread like crazy since I was a kid.
Goat is delicious, but bony. I think mutton would make awesome barbacoa and chilli.
FYI, Australian farmers are doing well exporting "rangeland" goats to the US: www.abc.net.au/news/2017-11-18/big-bucks:-feral-goats-are-being-recognised-as-a/9165384 I expect some US farmers/ranchers could do well with them given this.
a goat taco is a gyro and yes they are delicious
I understand that host has to add comments or ask additional questions to the guest in order to manipulate the topic a bit. But I couldn't stop feeling that Hank was in inebriated mind. The comments or questions he brought up were a bit arrogant and unattractive. Felt sorry for Dr. Nelson for his behavior.
Though the topic was interesting, thank you for inviting such a specialist.
Ok thats cool . i never knew the ringneck and Eurasian were different bc they seem similar. Also their calls!! Usually i hear the ringneck call and few times Eurasian but I NEVER KNEW IT WAS EURASIA!! I always thought it was a confused dove singing lol
Of course there are sheep and goat tacos!! There are called Barbacoa
Take a shot every time she says "leafy spurge"
You had me at lesbian pidgeons
Birria is delicious.
Good thing Jessi didn't bring a goat... Hank might have ate it.
Tacos de cabrón al pastor!

a.k.a. Jamaican Tacos
Super awesome. =)
Lamb taccos works for me.

Every time I watch one of these i think, "wow, Montana is so amazing!" Why is it that in the global zeitgeist or whatever, the US only seems to be made up of New York and California and sometimes Hawaii?
Hey, we have Texas too!
Actually go back to forgetting we exist our stories are rarely good.
Actual answer: It's because New York and California are the media centers of the U.S. and some of the biggest media exporters of the entire world. Montana is a beautiful state and one I wouldn't mind living in but as far as I'm aware it isn't particularly notable for any reasons. I believe most anywhere in a first world country should have areas with people interested in science and animals and such (try local animal shelters and universities if you want to join one, volunteering can help).
No idea why Hawaii is in this list? I mean it's well known but I can't recall any significant events that have happened since the volcano blew up a while ago and I can't even remember when. It wasn't all that prevalent in American media.

:000 okok maybe ill stick with restoration ecology xc
I STILL DONT KNOW WHAT TO DO
maybe just do trade school 😭
There's a pair of these doves in the tree in front of my windows. Years ago, there was a white one too. (that's in Vienna)
[note: how exactly does she write "eksetera"? *gnnnn*]
Etcetera? Etc.
@@thehoodlen Et cetera (etc.) of course. I was being sarcastic. It's pronounced 'etsetera', not 'eksetera'.
The redhead chick is quirky
use them for terraforming mars? i mean if they do so great here on earth they could probably have a good chance anywhere
lol no, mars only has 1% of the atmosphere of earth, and winters that average -40C°. maybe some arctic lichen can be more of help, but definetly not spurge.
maybe on some later stages of terraformation though.
How far from a house is a cat considered an invasive species? I've been hiking miles away from any home and have seen cats. Some with dead birds in their mouth.
They're invasive whenever they roam free outside. They kill stuff just for fun and damage ecosystems everywhere people live. On top of that people feed them and protect them from disease and extreme weather. That means there's not much damaging the population, which leads to many native animal populations continuously declining.
They also spread toxoplasmosis, which is a whole other thing and a huge reason to keep your cats inside.
Don't get me wrong, cats are great adorable creatures, but their place isn't outside killing birds.
@@bratatouille oh I know all this. We tend to rate animals by how cute they are. In my state, it is illegal to dispatch farrel cats, although I know plenty of farmers that have to every year in their barns. It's sad, but it is a problem that we created :-(
Am I the only one who came here expecting to learn about the ecology of restoring talk shows?
Love the ingenious solution to invasive species, and goat is delicious.
