Animals in a frenzy

D 2025

Drug alert in the animal kingdom! Animals use substances that we call drugs. Why? Chimpanzees have been observed stuffing their stomachs with fermented star apples. Are our closest relatives into alcohol and are they aware of its effects and consequences? Biologist Aleksey Maro is investigating this in Uganda. He is testing the alcohol content in the fruit and in chimpanzee urine: as much as a beer or two glasses of wine? The elaborately shot nature film not only discovers the secret of "intoxication in the rainforest" but also explores a small "high society" in nature: dolphins playing with the danger of a narcotic neurotoxin carried by puffer fish. Lemurs who get high on a poisonous millipede to protect their health, risking their lives in the process. Beetles that act as "drug dealers" and make an entire ant colony dependent and docile with a mysterious substance. And cats who indulge in a relaxing quarter-hour trip thanks to the beguiling effect of Nepeta Cataria mint.

In the second part, the nature film oscillates between fiction and truth in intoxicatingly beautiful images of jungle lianas, poppy fields and toadstools. In the Amazon jungle of Ecuador, jaguars chew on ayahuasca lianas. They are known for their psychedelic substance DMT. Ethnobotanist Rocio Alarcón wants to find out whether it also "works" on the predators.

In Namibia, the honey badger is exposed to the paralyzing poison of scorpions and shows symptoms similar to intoxication. In Slovakia, hundreds of swans ended up in an "opium hell". Why did they fall for the addictive substance in a poppy field and never get off? The New Zealand fruit pigeon with the melodious name Kererū loves overripe fruit. Is that why it is conspicuous for "flying under the influence of alcohol"? The legendary fly agaric can stun flies. But does it also send reindeer into a mushroom frenzy when they gorge themselves on red caps?

These are familiar or completely alien states, triggered by toxic substances found in nature. Intoxicating images soberly observe how it manifests itself, the intoxication in the animal?

Superfood beans

D 2024

Beans are true all-rounders: they stand for home and tradition, they connect generations and continents, they bring memories to life and are good for the intestinal flora and climate. It goes without saying that we will continue to be interested in beans in the future!

So it's high time that scientists took a closer look at the power legume and conducted a citizen experiment to investigate which varieties of the world's oldest crop will work best in Europe in a climate-adapted way. As part of INCREASE, over 1,000 varieties of the common bean will be cultivated by amateur gardeners in 27 European countries and characteristics such as growth, flowering time and yields will be meticulously documented for scientific purposes. The film follows the experiment and some of the participants with their different results. How else can we increase our knowledge about the diversity of beans?

While Dr. Kerstin Neumann at the Leibniz Institute of Plant Genetics and Crop Plant Research in Gatersleben, Saxony-Anhalt, leads the experiment and is committed to the preservation and use of (old) bean varieties, pulses and beans have always been part of the menu in Italian cuisine. In her restaurant in Chiusi, Tiziana Tacchi prepares regional varieties in a traditional climate-friendly cooking box.

Scientists are investigating the genetic characteristics of a bean and maize combination in fields in the south of France. What synergies make certain varieties high-yielding, sustainable plant partners?

In the Rhineland, farmer Karl-Adolf Kremer relies on the field bean as a sustainable, protein-rich crop that not only enriches the soil and provides food for insects and farm animals, but also has great potential for human nutrition.

Researchers in Halle (Saale) are therefore working on improving the digestibility of pulses so that nutritional and physiological benefits can be incorporated into innovative foods.

Because only those who know beans and know how to use them in their diversity will continue to give them value in the future. These are primary school children who rediscover the "dusty" vegetable in the school garden or bean enthusiasts from all over Europe who share and spread their bean wealth in Capannori in Tuscany and thus save it from extinction.

Species protection 2.0

D 2024

Scientists around the world are working to protect animals threatened with extinction. Because the sixth extinction of species is in full swing. Around 150 species disappear every day. In the race against time, researchers around the globe are now relying more and more on high-tech.

The visually stunning documentary is a journey to various scientists, start-ups and conservationists who are working flat out on futuristic technologies.

Martin Wikelski's idea is an internet of animals. The Director at the Max Planck Institute of Animal Behavior is researching the movement patterns of animals worldwide. His big data platform Movebank already contains over six billion GPS points. A global prediction system for life on earth is within reach.

In Germany, high-tech is to protect endangered bird species from being killed by wind turbines. At its heart: a camera-based system that uses artificial intelligence to recognize in seconds whether a red kite or eagle is approaching and stops the rotor blades in time.

In Kenya, AI software is set to help determine population figures faster and more accurately than before using photos. In the shadow of Africa's "Big Five", the numbers of giraffes have declined massively in recent decades.

And off the coast of Corsica, marine biologist Alicia Dalongeville sets off in search of a species that was thought to be extinct: the angel shark. She fishes in the depths for eDNA, also known as environmental DNA. Detective work in the Mediterranean!

Can high-tech become the key to species protection?

Sudden silence

D 2023

April 2020. A virus is forcing people around the globe to restrict their freedom of movement. It is estimated that by spring 2020, more than half of the world's population would have to stay at home. Governments around the globe had responded to the escalating COVID19 crisis with strict lockdown and quarantine measures. And suddenly, humans were much less omnipresent than they usually are. Suddenly there was silence.

Researchers quickly realized: This is a once-in-a-lifetime opportunity! For although the COVID19 pandemic has led to a tragic global crisis, it represents a unique opportunity to study the impact of our human actions on wildlife and the environment in general. A gift to science.

An international team led by behavioral ecologist Prof. Christian Rutz from Hamburg is analyzing movement data from animals around the world for this purpose. Mini transmitters, video cameras and photo traps have recorded the hidden lives of wild animals - before, during and after the lockdown. A unique global experiment! How have animals changed their movement patterns or behavior? And can the pandemic be an opportunity to develop strategies for better human-wildlife coexistence? Rutz, who teaches at the University of St. Andrews in Scotland, sees great opportunities in the study: "We can find out how humans can share the rather limited space on this planet with other animals. Sometimes it could be restructuring transportation networks, sometimes it could be closing beaches during breeding seasons. Even if humans can't always stay lockdown - and no one is asking us to - small changes in our everyday behaviors could benefit nature."

Sudden silence accompanies scientists around the world, for example in Italy, the Czech Republic, Canada and Tanzania. The film illustrates the effects of the break from humans (the so-called "anthropause") on wildlife such as deer, brown bears, rhinos and orca whales. At the same time, much of this data contributes to the mega-study, which is overseen by researchers Christian Rutz and Marlee Tucker. The results reveal a complex picture of need and opportunity for better human-wildlife coexistence on our shared planet.

What to do when the spruces die? - The dispute over forest change

D 2022

"We thought climate change was progressing gradually, like a dimmer switch on a floor lamp, but it's actually more like a toggle switch," says Katharina Pietzko, forestry office manager at Thüringenforst. She is currently seeing entire stands of spruce being sacrificed to clear-cutting. Due to drought and bark beetles, the shallow-rooted trees, which need a lot of water, have died in large areas all over Germany. "In 25 years," says Andreas Bolte of the Thünen Institute, "extrapolating the death of spruce, there is a possibility of this tree no longer existing in Germany." Yet spruce is the "bread tree" for the timber industry, processed into roof trusses, bookshelves, wooden pallets, wood chips. The forest, hoped-for saviour in climate change, could now become its victim.

Forests are thus becoming a contested bastion between the timber industry and nature conservation. Forests are supposed to help lower carbon dioxide levels, for one thing. They are supposed to satisfy the ever-increasing hunger for wood. They are supposed to cool the landscape in the coming hot seasons. As renewable energy, they are supposed to relieve the consumption of fossil fuels. And be a habitat for animals and plants, a place of recreation for people. How can the forest do all of this? Ecological and economic demands seem to compete irreconcilably with each other.

To explore this conflict, "Exakt die Story" is on the road with foresters, forest owners and scientists in Thuringia, Saxony-Anhalt and Brandenburg. The forest experts show how forestry works and how management can also harm the forest. They talk about what a near-natural forest is for them and how it can be made strong for the new climate. Their insights into the tree species of the future are a topic, as are the future rewards for forest farmers. They are all engaged in a sometimes very controversial debate in search of a common goal: the right plan for a sustainably healthy forest.

The production "What to do when the spruces die?" was created in collaboration with the author Katharina Beck.

The Presidents' Tailor

From Auschwitz to the White House

D 2024

Maxmilian Grünfeld spoke Yiddish, lived in Czechoslovakia, lost his family in the Nazi concentration camps and had no business experience. Martin Greenfield lives in Brooklyn, speaks English, tailors suits for US presidents and runs a bespoke clothing empire with clients and friends from high society.

It is the same man who is now a 92-year-old fashion legend, tailor to US presidents and celebrities, and a bon vivant of the city. Mr. Greenfield is an hour-long documentary that tells the story of a man who, against all odds, went from being Maxmilian Gruenfeld to Martin Greenfield and how he is now coming to terms with his own legacy.

The secret of the birds

D 2021

The web series "The Secret of Birds" was created in cooperation with the author Kerstin Mauersberger. Together with the amateur ornithologist and birdwatcher Silke Hartmann, we accompany bird enthusiasts who tell us about their fascination for bird songs and birdwatching, and who cast a spell on us along the way! In addition, researchers and experts show us how birds adapt to adverse living conditions and what we humans can learn from them.

The series consists of the three episodes: "Listening and Seeing", "Researching and Understanding" and "Coming and Going", which can be accessed via the ARD Mediathek. In addition, a 43-minute summary documentary was produced for MDR.
