2 2 2 2 2 in meeting cultures around the world, people learn to classify small handful of animals with edible and all the rest of the classify as disgusting. a donkey series about our complex relationship with animals. the debate watch now on youtube dw documentary, the bio diversity, genetic engineering animal behavior, and artificial intelligence. drones by syria and split that lo, how the animal kingdom helps the science coming up on the show, the content to the new edition of tomorrow. today the gelata is also known as bleeding hard monkeys live in the field in the highlands,

at altitude between 224400 meters. although jolanda so closely related to bathrooms, they belong to their own genus, and i'll be only probably needs to eat grass. but despite the very specific ecological nation, these mountains, though not safe from humans, like many other species, gernado. so i mean, i, you see and read list of endangered species within the middle of a bite of us the crisis. so we need to have the scientific understanding of why of some space is being impacted so heavily. july, those have very complex group behavior. similar to planes, the president can yeah. small groups of females with one male and each group join up to find logic groups containing several dozen animals. that's why scientist set the max punk institute for neural biology of behavior are studying both species.

they want to test out a new method for monitoring the social behavior of animals in their natural habitat . the my previous research was on was very much sort of standard behavioral ecology where i was sitting in a jeep with a pair of binoculars watching an animal. and i found that i was limited and the questions i could answer was that method, i can only watch one animal in ducks for any period of time. but to look at the questions regarding collective behavior and how groups of animals respond to things like predators, you really need to see the behavior of the whole group at once. and that's just not possible for one person sitting in a jeep and so i had thought to use drones. layer castillo and her team are combining drone technology with the newest possibilities of technical monitoring, known as computer vision. special software analyzes the drug one's digital video's using a i,

and replicates the function of the human brain which can recognize individual objects. by analyzing patterns. the computer uses this information to make its own decisions, prognosis and assignments like following one specific animal. for example, this method is called deeper learning that has become standard practice at the max plants institute, and so it wasn't germany. the thing there costello and ian cousins arranged a video chat with ben kogan but he currently works. i think university of washington units and program to a deep learning algorithms for the jerome project. so the model actually learns from, from the images that we give it. or basically we take a subset, maybe a couple of 100 images, maybe a couple 1000 images. and we, as humans go through and actually pilot jobs that we're interested in. so say if we're interested in finding zebras, then we take these images and then draw little boxes on the computer around the zippers and the images that we care about. and then what we can do is we can take

those images, so all the annotated images and give them to these models. and then basically ask the model to find a set of parameters that highlight those objects. we care about not just in the images, give them, but in lots of other images that has never seen before, basically, so they can learn those, those patterns. with the help of computer vision, the behavioral biologist can observe how hurts respond to ecological changes in their environment. caused by climate change or human interventions. the animals don't notice that they're being observed. they don't need to be captured and fitted with the sensors. the max blank research team gets all the relevant data. they need this way, the for the savers. we fly at about 85 meters above the ground, which is high enough that they're typically not disturbed, but we can still get really high resolution imagery. because we still, i'm in high definition. we can see not only the animals location,

but also what it's doing. we can see if it's visual it, we can see if it's feeding, we can see if it's interacting with other zebras. up at the top, we see the trucks of the animals and the pixel coordinates of the video frame. but this doesn't allow us to disentangle. the movement of the animals from the movement of the drones. and so it's really important that we're able to project these tracts into geographic coordinates, and that's what we see on the map. so we see that we can translate the tracks from the pixel coordinates into the real world and see where these animals actually are and how they move in environments. the combined a i technical image analysis works well with both the planes, zebras and kenya, and the jet lot is in the field because of both groups. we've helped me open plainly visible from above around the very beginning. this is a breakthrough in our ability to get these types of data for certain things that the animals in the real world. and so what we now need to do is to expand this expanded studies across the globe. so we can understand things. in fact, humans of having and was like,

there are only 20000 gelata is left in the wild by studying their social behavior using drones. the marketplace research team is hoping to gain new insights into early human history as well. to a lot of those are the only other primates besides humans not to live intrigues. the evolution of our human ancestors started several 1000000 years ago, but our planet is much older. so what was happening here for all those billions of years? the 1st forms of life to image with bacteria, organisms that seem relatively simple, but are actually very complex. but to be of many properties, some can even glue. but what's the actual purpose of light producing bacteria? as far as we know, that area don't have a single isn't that good to touch these light signals?

there is a theory that you developed in and in bacteria when the bacteria could be as, as a group, could see it can't be seen as individuals, right? they're too small for the eyes to see, so they can be seen. and so they evolved at the time when, when complex sizable. why would like terry a want to be seen by law geronimo? for a long time, scientist was really sure, until a tiny inhabitant of hawaii is close to hold his date of the team. some claims now he chose to night. the hawaiian folk tale square matches from hiding to hunt, smoke, crops, and trim under the cover of darkness. to avoid becoming something else his prey under the moon and starlight, the users have a trick closed overall,

so it becomes illuminated by the light that emanates from february fishery bacteria that have a special liked and missing oak. and these bacteria cover the entire surface of the split skin. using best lights, the roughly 5 centimeters long squared can cost lights on its own shutter and make itself practically invisible to predators. the this is so it makes them difficult for researches to detect but not impossible. yes, we've got one. this is an adult female form. bob tells good. if we ship or tomorrow morning, she'll arrive the following morning. so she spends about 20 hours in a cooler and in transit. usually they show up wherever we ship them and they're happy and just hanging out waiting. the little squid has a full 1000 kilometer slides ahead of her before she could move into the new home

and they live in pasadena together with 9 other males and females. she'll be not children, cad, for under a very special conditions, so that she produces as many of the spring as possible. and we'll see life below a certain wavelength, including our guess of a certain wavelength or red light. and so we can work in red light and they cannot see us. so we can come observe them in their nighttime and watch them each and hans and lay eggs. and they don't over here. previous studies have already given the great lots of important information about the symbiosis between squared and bacteria. for example, that the glue called fire luminescence seems to have communication purposes.

we know of no particular reason for the expect jerry to make by luminescence, except in symbiotic associations where they make the light for an animal host such that that host can now use the light for a variety of its behaviors. and what we found out to our surprise was the amount of light each individual cell made changed when the bacteria got to a certain density in that liquid. and this gave us the idea that the bacteria were communicating to each other. and we began to realize that bacteria have many behaviors just like more advanced animals and plants that are not visible until you look very close to the mechanism by which bacteria communicate is called form something. they use various signaling molecules that allow them to detect squats

around them. one signaling molecule determines which species are nearby and then also determines the concentration if that right and species. if it's high enough, the bacteria old switch on the lights at the same time. and the squared also seems to be positive, this communication network in every square centimeter of water. there are a 1000000 bacteria, a 1000000 bacteria. and in that they're about only about a 100 of those 1000000 bacteria or gabriel fish. so one of the things that has to happen is when the baby's hatch from the egg within 3 hours, they are able to pick out of the sea water the right. there's somebody out there able to recognize there's somebody on this extraordinary ability shows that the communication between highest impact area is much closer than scientists previously

believed. is this alliance earlier this summer, alina's was believed to be on the loose in germany. it turned out to be an environment mistake, the big cat with actually a wild full it's pretty easy to get members of the animal kingdom mixed up. especially if there were only droppings to go on. analyzing dna pascals, finding the environment could make it easier. one new method is being tested in switzerland. this water sampling lake called view that contains a wealth of information as well as potential for animal conservation. christy diner from the e. g h zurich, researches environmental dna, which is also known as e d. n a. it's a new method of species identification. it's primary objective is to revolutionize the monitoring of bio diversity around the world. what's really exciting about

environmental dna is that it's like capturing all the stars in the universe. we have every piece of dna from every species potentially floating around in this water and we're pushing it in. and it gets harder and harder the more watery filters, because the more things we're collecting. and what's really exciting about this is it's quite simple. all we're doing is filtering a little bit of water 100 milliliters, and from that we can potentially say all the species that are living in this entire landscape, including the marine creatures and the land. animals that live around and in they called in the sample contains not only dna from aquatic life using traditional methods to monitor such a large area is time consuming and expensive. during field work that sometimes lasts for weeks, plants, phone guy, animal species or their excrement are collected, counted,

and recorded. environmental dna is a huge timesaver. neither animals, plants, nor any other traits like voice or excrement, are necessary for the classification. just tiny pieces of tuning are sufficient and vague can be found in abundance in the environment. every living thing needs permanent traces of genetic information. you may use everywhere in folio experimental feathers and even mucous, when it's collected in sequence. a quick check of a dna database is all it takes to determine the species. at least in theory, because some important information is still missing. biologist luca, steve on taura from the time to an hour ago, uses the new method to monitor li calls used for invasive species like crack of muscles and fresh water prongs. these are already well documented in databases. a

deal. i'm see, i have a new biography protection programs here at the lake, which is a program that allows us to use various methods and so that new, new invasive space size and then got the milling off. and this is a way to check if it's effective. you, we want to know of something new is arrived or not, and all you get home these homes. well, lucas stephen tour is searching for just a few species with the environmental dna method. christy diner wants to explore the entire habitat surrounding the lake. the cheese, clearly thinking bigger because dna travels, she thinks it will work. what's fascinating about dna is but once it gets into water, it actually moves with the water. and if you can imagine a dna, a piece of dna getting into a river that flows to the lake, this lake behind me acts like a sponge in the landscape. and it's soaking up all that dna. and it's potentially

sitting here for enough time that we can sample it. the information we get is for the entire water shed. so all the land you can see coming where the rivers we've come into this lake. and that gives us a very easy way to sample simple a few samples, but for an entire area of water share this with land area that drains whatever water collection it to the same place like home view has a water chad or drainage mason of 128 square kilometers the, the team is researching a total of a large makes that of drainage patients of varying sizes. supposedly the bigger of the drainage basin, the greater the bio diversity and the lake. the name of the research project is to establish whether this theory is correct and to find out how much dna actually ends up in the lake. the chemical physical and biological

factors like sunshine, temperature, and ph values influence how much the dna degrades. on its way to the lake, beyond that, the analysis of the gathered samples provides dna sequences that are basically sequences of letters. which sequence corresponds to which species is something that has to be searched for in reference, data banks, it compare is stored sequences with those found here. the problem is that the databases are incomplete. not all of a species found on to your are included data on invertebrates, are especially lacking. many ambitious projects are under way to change that in the coming years. and despite the various hurdles, environmental dna is already causing a stir in the world of science because of its huge potential for scientist, for biologists, for ecologists, this is really

a paradigm shift because we're able to access information that was never possible before. and so there's about 1400000 lakes in the world that are 10 heck, there's a bigger and if we look at the land that is in contact with all of that, that's 25 percent of the earth. so it could be that we go to a 1000000 or so lakes and we can sample a large proportion of the earth, maybe every year. and that's possible to do um with this kind of technology, a species go extinct every day. researching biodiversity more efficiently and across the larger areas is more important now than ever. it's the basis of species conservation. humans are destroying more and more florida. devastating animal habitats in the process. but sometimes humans help animals rooting that how to take the american bowl from it was important to us from the us

pond. it's been probably being understood in the wilds that is until now. so, splunk, this light can also cause what looks like any of them. but look closer, and you'll see it's home to an animal that actually doesn't belong here. the north american bull from native ship hawks of the us, canada, and mexico. the from the now spreading throughout because gwen region adult films will eat anything they can, including other i'm fabian's, and even smaller rodents. the tadpoles can reach 10 to 15 centimeters in length and have no natural predators in the lakes here. no one is really sure how bullfrog came to be here, but that all theories, bonds found well just please give us a year or 2 ago, you can legally bible from the top polos impact store to expand. it was great for

kids to watch the top it all is great, but then you end up with a problem of just getting bigger and bigger. balls positive on that. if you can't keep it in the garden anymore, but you also don't want to kill everything. so people released the folks into nature, the low to burn in each tooth. no, no, but i did not to and left over you come by, tadpoles anymore, and the damage is already being done. and since the folks are on the list of invasive species, the numbers have to be controlled a few minutes in kind of a sure i'm 50 and so generally under protection and can't be removed the home we have special permission to and these people folks, oh, those are allowed to die denarius' the on position. these don't fidelity thing on his toes by send handle the behind organizes regular events to catch the frogs today she's working with 10, dave, it's the summer market that i've already felt about who should go with the team. have a look at start. so casey group one comes and show up to, um, from, from terminal to among them is biologist kind of showed he wants to learn more

about the spread of the frogs and tadpoles. he studies the tadpoles that his lab at the institute to buy a materials and bio molecular systems in short got so ones. this is myspace. it's important for us to understand how the bullfrog develop that where they're living, and especially where they will be hyper needing. but we have to understand the ecology of little frogs, if we want to control them effectively if it came from nucleus and effective control is needed, because it's not clear whether the measure of use so far like the dive all working . this wasn't, you know, let's see on the last 10 years, they around 60000 tadpoles up an account and remove the funding. but to what extent you can find change the bullfrog support, have them completely disappeared from this habitat that will only become clear in the next few years. at the end of next year, onside the back of the lake. it's starting to get the best time to catch the tadpoles, the

underwater, the drivers don't have to look for long, easily catching one tadpole off during now. but the band though with around 500, but the hand of the gun says they've previously caught twice as many, she's not diving choosing to use net along the show instead. here that team regularly catch brooks that are past the level stage. like this little guy estimated to be about a year old and still not sleep grand. the bullfrog is already much bigger than the adult roles and frog that's native to the area. it wouldn't stand a chance against the full grin. bull from. kind of little one says the humps the tadpoles is having an effect. the most of the time is catch the few. they find next

time. but a single adult female bull frog place, tens of thousands of eggs and without natural predators. many of the type of all survives so it's unlikely that both drugs can be eliminated from this positive gemini, simply by catching tadpoles. if i was blood is red. why do you have a question about the animal kingdom of the world of science, st tech? just send this a video, text or voice message. if we answer your question in the, so we'll send you a little surprises and thank you. so come on just all this week. question comes from me, your honda about sista in colombia to animals dream. they can tell us about their dreams, of course, but that hasn't stopped curious, scientists from looking for answers in 2001 researchers at boston's mit

metro at the brain. waves of lab rach 1st in the maze, searching for food. and again, while they were sleep. ready the results show that during sleep, the same brain areas were active as during the search for the rats were mentally retracing their journey through the maze processing what they learned during the day. the sleep studies have also been done on c prof inches while sleeping, the internal trip to the melody of their songs, to sing songs the song during the day. research has concluded that these birds do, in fact dream of singing. in humans, the sleep phase most closely associated with the dreaming is rem more rapid. i'm movement as the name suggests, this sleep phase is characterized by quick, uncontrolled eye movement. people who are awakened during rem sleep can often

recall their previous dream in detail range sleep can be observed in almost small mammals. when our pets twitch round bark on the out, it's very likely that every living moments of their day in their dreams. what dreams sleep has just been seen and mammals, these cut off fish and twitched their eyes and tentacles during sleep and came even reflexively changed. color sleeps, these are similar to ram. have now also been identified in reptiles for the researchers, an indication that different sleep phases must have already been developed in prehistoric times. and what about insects or spiders? a recent study found that jumping spiders can twitch in their sleep, similar to other animals during remo, sleep evidence that even they have dreams. the

best fit for this edition of tomorrow today dw science. thanks for watching. and see you next time the, the, the,

a pulse, the beginning of a story that takes us along for the ride. it's about the perspectives culture information. this is the, the news w, mines, garbage dumps and remain,

you think of trash and corruption. the country is waste management industry is approved with problems, trash, assembly sausage on pipe. but even the model projects don't meet you standards. they are showing which fund wasted is up in 75 minutes on d, w, the lice universe and every thing the answer. well then, given here the answer to almost

everything we're documentary series with carver and the ground to breaking questions going speed after life. the government for a city saving the world, questions for the present future heads filled with the ideas. 2 and when we learn something, the hardware and software of our brain changes. so get ready for the brain. 40 to the answer to almost everything this week on the

this is the w news live from berlin, russell book set to ask north korea for weapons. us media say that north korean leader kim jong on will travel to russia or talks with vladimir pretend. the 2 countries have so far denied that any north korean arms have been used in the bushes war against ukraine. still coming up for my grand votes leaving tanisha, we need a band prepared to risk his life to travel to europe.
