Sucky Fish & Relationship Advice from Ants | Natural News from The Field Museum | Ep. 3


Heey and welcome back to Natural News from
The Field Museum! Todays stories include exciting dinosaur discoveries, things that suck, and the importance of not becoming a parasite in any long-term
relationship you may have. Lets go! Fishes collections manager Caleb McMahan and
co-authors recently had a publication in the Occasional Papers of the Museum of Natural
Science from Louisiana State University about something that SUCKS. Literally. Hypostomus niceforoi is a species of suckermouth
armored catfish that is found in Andean streams in Colombia, Venezuela, Ecuador and Peru — but
this new paper reveals that the species has recently been collected from Lago Nicaragua,
in Nicaragua. And given the big geographic leap and saltwater
barriers, the fish probably didnt swim there, BUT.. it may have flown. At least, part of the way. See, ornamental fishes often travel thousands
of miles from their original homes to end up in your fishtank. The papers authors believe that this fish
trade is the reason why a South American catfish was found in a Central American lake. The ornamental fish industry has been in place
in Central and South America for decades, and when sustainably and responsibly managed
this industry provides jobs for thousands of people. But, when pet owners grow tired of their scaly
pets and decide to dump them in a local water system, its seriously bad news: one estimate
is the aquarium trade has contributed to a third of the worlds worst aquatic and invasive
species, which makes that one scene from Finding Nemo not NEARLY as endearing. Armored catfishes like this species of Hypostomus
can become entangled in fishing nets and ruin them, due to their long spines and barbs. More dramatically, different species of armored
catfishes are known invasives in other parts of Central America and the extent of their
negative impact on those environments is not yet fully understood. So let this be a friendly reminder and dont
dump your fish! If youre looking to get rid of your pet and
its still healthy, consider returning it to a pet store, or donating your setup to a school
or retirement home. Because even if you think youre saving one
fish by releasing it into the wild, you could be irreversibly damaging an entire population
of native fishes. And thats a bummer of a thought! —
Weve got an update from Field Correspondent M. Lee Grass Lee, who is reporting on recent
dino finds in Utah. Fossil preparator Akiko Shinya and curator
Pete Makovicky are out west doing some good, ol-fashioned prospecting with a few other
staffers hoping to strike paleo-gold. Lets go to the Field. Thanks Emily. Were back in Utah here with Pete and Akiko
where theyve spent three weeks conducting field work on the lookout for dinosaurs – and
boy is it hot. While searching for these 112-98 million year
old remains, the team walked up to 12 miles a day in 100 degree heat. But diligence pays off, and after a week of
nothing they scored big when they discovered a partial skeleton of a probable armored dinosaur. The team also salvaged a small, Late Jurassic
herbivorous dinosaur, which had been located by a state geologist and then run over by
local dirt bike enthusiasts, as well as the skeleton of a large sauropod. The paleontologists gave no additional details
on that find so far, but well know more soon. Back to you! —
Thanks M. Lee. Museum media producer Greg Mercer joined the
team in Utah and provided those clips for us! If you want to learn more about that particular
field trip, be sure to stay tuned for his mini-documentary, comin at you soon. And now – ants. In Lewis Carrolls book Through the Looking
Glass, the Red Queen tells Alice it takes all the running you can do, to keep in the
same place. Biologists took this phrase and ran with it
(PUN), and today in biology, the Red Queen Hypothesis refers to the pressure on competitive
species to evolve as rapidly as possible so as to outgun their competition. But in the last ten years, statistical modeling
has suggested the opposite is true for mutualists, which are two species that each benefit from
the activity of the other – like when you do the dishes because your partner made dinner. This is called the Red King Hypothesis — the
idea the the two mutualist species evolve at a slower rate, so as to avoid interrupting
their beneficial partnership. All hypotheses require testing, and curator
and ant scientist Corrie Moreau and Princeton post-doc Ben Rubin were curious to find out
how long it takes these mutualist relationships to evolve between two species. They examined the bonds between acacia trees
and certain species of ants side note, if you remember in our video What the Function?
we learned with Destin from SmarterEveryDay that certain stinging ants live in the hollowed
thorns of acacia trees. The tree provides food and shelter, and in
turn, the ant protects the tree from elephants and other grazers who might eat the leaves. In non-scientific terms, thats what you call
a win-win. Corrie and Bens findings were published recently
in Nature Communications, and they discovered something unexpected, which is that mutualists
actually evolve more quickly than competitive species, not more slowly, because they constantly
need to adapt to their environments and keep up with changes of their mutualist partner. Corrie proposes this is because many species
switch between mutualism and parasitism over time you stop offering to help with dinner
or do the dishes, and that relationship becomes pretty one-sided. So each species needs to react quickly to
their situation, meaning faster rates of evolution. So the lesson from this is that its important
to work hard on maintaining balanced relationships, and both sides gotta put in the effort. Otherwise.. One of you is going to turn into a parasite. I really shouldnt be giving relationship advice. —

  1. I love your show for the interesting details we don't usually get to see and for your easygoing charisma. But I'm not going to lie, your accent is a big supporting factor.

    My dad's family is from Michigan. I guess it's nostalgic for me.

  2. So, this format is cool, raising awareness of recent research and all, but am I the only one who misses the old one? If I don't hear a "…still has brains on it" at the end, it doesn't sound right to me.

  3. Euh silly thought, would you take one of my polar bear figurines and use it in your set? if so where can I send it to? love the brainscoop and silently are smitten by its presenter. no need to worry. I shall not stalk thee, I am way too lazy for such a thing and too far away. and too old. Soo what do you say before I make a creep out of myself out even more than i already have. which i am not btw. ๐Ÿ™‚

  4. I WANT AN EVERYTHING IS DEAD SHIRT DAMMIT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  5. Ruh roh! You fell into the common pleco trap. The image at 1:43 is a Pterygoplichthys species, most likely P. disjunctivus, not Hypostomus plecostomus. Confusingly, several species share the same common name. Anyway, great to see some Loricariid representation; it would be great to hear from Caleb about his work.

  6. I sense that the inspiration for M. Lee's accent is taken from Emily's Northern roots in Montana. It's very folksy.

  7. My friend surveys turtles in the southern US and there are ponds stuffed full of plecostomus!! They try to remove as many as they can catch but they're not set up to do that specific task well and there's sooo many ๐Ÿ™ It gets worse as huge numbers of burrowing males(!!!) majorly erode the banks.

    I really like this format of reports on papers the museum has recently helped publish!!! Like this should be standard for every museum because I like seeing how the museum helps directly.

  8. Love all of your hard work! I really do! Please never stop doing what you love, and if you stop liking it, I simply hope I will enjoy you next projects at least as much! <3

  9. PLEASE don't do this often. Yes it might be neat occasionally but what makes your channel so great is the stuff from around the collection. Any channel can talk about stuff but yours is able to see all this stuff in the museum. Please do more of that.

  10. QUESTION. kinda random but were there any mistakes made by paleontologists while looking for fossils? like did they crack a fossil in half or break it in any way which ruined the fossil?

  11. Actually, your relationship advice here is solid, and I'm not surprised that it applies to the natural world as well.

  12. Is there going to be a Halloween edition of Natural News? Is there any part of the museum that is rumored to be haunted?

  13. The next time I come across a fan of Matt Ridley's 2003 book, I'll play this video from 3:22 and just save myself the trouble.

  14. I love this series! I've always wanted to keep up with academic discoveries but had never found a satisfying option until now.

  15. You are a "Natural" at this! Emily, if you want to know what happened to the Fish that escaped in "Finding Nemo", you have to watch "Finding Dory" ๐Ÿ˜›

  16. Suckermouth catfishes (a.k.a. Plecos) have already severely impacted many rivers in Central America (and not only: also South East Asia and Australia I believe). They have no natural enemies there and breed by millions. Their populations peak when they simply cover every imaginable space on rocks or sand bottoms of rivers in these areas (locals catch them and make them into fish meal for chickens for instance – but that is a drop in the… erm, the river).

    They do not eat native fishes themselves, but eat their food (e.g. algae on the rocks), destroying local food chains – and that may drive some native species extinct. Fortunately, after populations reach peaks, they start to decline, but what is hard to assess now is how they influence local species in the long run.

    Definitely a dark side of this fascinating hobby, but stupid people are everywhere.

  17. That sucky fish is really a dangerous invasive specie in areas that it doesn't have its natural prey..
    Here in Philippines a lot of bodies of water were invaded by these fishes, Like the famous Pasig River in Manila and the Lake that connects to it Laguna Lake and other connecting rivers. It's quiet a head ache for use co's they cause other fishes to leave or die, the Pasig River and Laguna lake that once abundant of St. Peter's fish and Milkfish is now lacking of those local species plus, they cause the River Mud to be unstable because they dig them up. If you like Emily I will post a video of the Sucky fish invaded River and tag you in it.

  18. This is an extremely well-polished presentation. And Field Correspondent Emily's accent is adorable, dontcha know.

  19. I find it amazing that any captive fish could survive the shock of being dumped in such foreign waters of different chemical and thermal composition.

  20. this is my new favorite thing. natural news, i mean. the brain scoop is an old dear friend of mine. i'm a bit behind on videos though because life happened (why aren't there more hours in the day!! i need more) but this is great. and i'm going to catch up on videos in the most efficient way possible … by translating them. i'll be done by christmas 2167. worth it though <3 <3 <3

  21. many fish from the family loricidae (South American armored catfish) are worth $100's of dollars and the sheer number of species is mind boggling! Many of them all though popular amongst collectors are simply known as Lxxx (i.e. L145.) They are very important to the port trade as well as South American fishing economy. A sheered net is peanuts in comparison to a potential $10-$50 the fishermen make per specimen.

  22. An interesting side note to the acacia-ant mutualistic relationship: A 2013 study by M. Heil et al. suggests that Central American acacia trees produce a protein, chitinase, in their nectar that inhibits the ants' invertase (enzyme that allows for the digestion of sucrose). Meanwhile, the tree also includes invertase in the nectar, so it is already sucrose-free. Basically what this means is that once the partner ants eat nectar from the Acacia, they can't digest food from other sources.
    For more information, read the paper: "Partner manipulation stabilises a horizontally transmitted
    mutualism" by M. Heil et al.

  23. Goldfish also tend to destroy the local ecosystem when they are released from domestic aquariums … they can survive the cooler temperatures of the northern US and Canada, whereas tropical fish not so much ๐Ÿ˜‰

  24. yes, you should be giving relationship advice. Good stuff. I will be using your example as I am a Marriage and Family Therapist. lol

  25. It's so irritating that people buy fish, do no research on it, and then release them into the wild when they get tired of them. Moron's like them ruin it for serious hobbyist who can't buy piranha's or crayfishย because states decide to outlaw them.

  26. I feel like sucky fish are the type of fish that get invited to a private affair and then bring a plus one without asking.

    How about this, sucky fish will thumbs down a video because they have fins. Imagine the resentment it takes to crap on well produced content just to make a political statement on inclusion.

    Sucky fish will often put flying fish down as sellouts. It's kinda funny and they have half a point, but it's very hurtful.

    Sucky fish will sign a card but not chip in for the gift. So there is now no distinction as to who went the extra mile. It's like signing the Vietnam Wall when nobody's looking. You weren't there dude. You weren't even a medic or cook. You can't sign in the name of feeling their pain. Oh, by the way that analogy is perfect, there is no difference. It's the same level of offense, that's why it works so well.
