the meeting cultures around the world, people learned to classify small handful of animals with edible and all the rest of the classify as discussing the w series about our complex relationship with them and also need to be watching. now on youtube dw documentary, the bio diversity genetic engineering, unable behavior, an artificial intelligence, drones by syria, and split the clue 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. heart monkeys live in the field in the highlands
7:31 am
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 do not say 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, zebras and kenya. small groups of females with one man with each group. join up to find logic groups containing several dozen animals. that's why scientists set the max punk institute for newer biology. a behavior are studying both species they want to test out a new method for monitoring the social behavior of animals in their natural habitat
7:32 am
. 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 the thought to use drones. layer costello and her team are combining drone technology with the newest possibilities of technical monitoring, known as computer vision. special software analyzes the drones digital video's using a i and replicates the function of the human brain which can recognize individual
7:33 am
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 the type of learning that is become standard practice at the max planck institute. and so it wasn't germany. but i think there costello and ian cousins arranged a video chat with ben coker. but he currently works. i think university of washington units and program to a deep learning algorithms for the jerome project. so, you know, 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 nationally highlight the optics that we're interested in. so say, if we're interested in finding zebras, then we take these images and then draw the boxes on the computer around the prison, the images that we care about. and then what we can do is we can take those images
7:34 am
. 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 it's 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 intervention. the animals don't notice that they're being observed. they don't need to be captured and fitted with 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,
7:35 am
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 tracts from the pixel coordinates into the real world and see where these animals actually are and how they move in environments. the combined a technical image analysis works well with both the planes, zebras and kenya and the to a lot, as in e, c o, b, a because both groups leave to help me open plainly visible from above. around the very beginning. this is a breakthrough in our ability to get these types of data for endangered 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 that in fact, humans are having and was like, they're only 20000 to
7:36 am
a lot us left in the wild by studying their social behavior and 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, fox, terry, i don't have a single organ that could detect these light signals. there is
7:37 am
a theory that you developed in an in bacteria when the bacteria could be as, as a group could be seen. they 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 a. why would like terry a want to be seen by law geronimo, for a long time scientist was really sho, until a tiny inhabitant of hawaii's cruise to hold his date of the team. some claims now he chose to night, the hawaiian folk tales squared the matches from hiding to hunt small crops and shrimp under the cover of darkness. to avoid becoming something else as pray under the moon. and starlight that uses we have a trick closed overall. so it becomes
7:38 am
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 squint skin using best lights, the roughly 5 cents meter long square to can cost light on its own shop 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 tests. 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
7:39 am
and then live in pasadena together with 9 other males and females. she'll be not shooting tad 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 and 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 globe called bio luminescence seems to have communication purposes.
7:40 am
we know of no particular reason for the expect your 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 communicates as cold form something. they use various signaling molecules that allow them to detect squats around them. one signaling molecule determines which species are nearby and
7:41 am
then also determines the concentration of 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 they're able to recognize. there's somebody on this extraordinary ability shows that the communication between highest impact area is much closer than scientists previously
7:42 am
believed. is this a lion? earlier this summer, a lioness 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 hall view contains a wealth of information as well as potential for animal conservation. christy diner from the ex 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 biodiversity around the world. what's really exciting about
7:43 am
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 sail all the spaces that are living in this entire landscape, including the marine creatures and 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 fund guy, animal species or their excrement are collected, counted, and recorded. environmental dna is
7:44 am
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 means permanent traces of its genetic information, teenagers everywhere, in foliage ex, permits feathers. even mucus, 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 lucas, steve and torah from the come to an arc out, uses the new method to monitor the calls used for invasive species like clack, of muscles and fresh water prongs. these are already well documented in databases. let's keep p a c. i have a new biography protection programs here at the lake,
7:45 am
which is a program that allows us to use various methods and so that new new and base, so space wise and, and got the milling off. and this is a way to check if it's effective outcomes. we want to know if something new is arrived or not, and all you get ahold of these problems as well as lucas stephen tour is searching for just a few species with the environmental dna method. christie diner wants to explore the entire habitat surrounding the lake. she's 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
7:46 am
the entire water set. so all the land you can see coming where the rivers would 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 would ever water collect significant to the same place. make home view has a water chad or drainage basin of 128 square kilometers. the team is researching. a total of a large makes that of drainage patients of varying sizes. supposedly the bigger the drainage basin, the region with the bio diversity in 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
7:47 am
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 the species found to your are included. data on invertebrates are especially lacking many ambitious projects are under way to change that in the coming years. despite the various hurdles, environmental dna is already causing a stir in the world of science because of its huge potential refer scientist for biologists for ecologist. this is really a paradigm shift because we're able to access information that was never possible
7:48 am
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 everyday 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 habitat. take the american bowl from. it was important to us from the us
7:49 am
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 for up to now spreading throughout the cons. glove 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, fonts by on the road to a guy, you can legally bible from the top polos impact store to implant. it was great for kids to watch the top it all is great, but then you end up with
7:50 am
a problem. they've just gotten 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 his tooth number 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 kindergarten. sure, i'm 50. and so generally under protection and comp be removed, the home we have special permission to and these people folks, oh, those are allowed to die. denarius' the onto officially zone fidelity thing on his toes by send handle her 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 in, charlotte and um, con, sometime motor 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
7:51 am
institute supplier materials and bio molecular systems in short got so once this is miss page, 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. lucas and effective control is needed because it's not clear whether the measures used so far like the dives all working. it's wouldn't you know, let's see on the last 10 years like around 60000 tadpoles up in the account and remove the funding. but to what extent you can find chain, 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 on site. back to the lake, it's starting to get the best time to catch the tadpoles. the
7:52 am
underwater, the drivers don't have to look for long, easily catching ones have toll off during nova the bands out with around $500.00 but the end of november. and since they've previously called 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. the bullfrog is already much bigger than the adult, was the frog that's native to the area. it wouldn't stand a chance against the full grin. bulls from kind of little one says the humps the tadpoles is having an effect. the mobile, the dive is catch the few they find next time. but
7:53 am
a single adult female bullfrog placed 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. let us read why you have a question about the animal kingdom of the road of science and tech. just send this a video, text or voice message. if we answer your question in the, so we'll send you a little surprise because the thank you. so come on just all this week. the question comes from many your honda about sista in colombia do animal 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
