How Plants Measure Their CO2 Uptake
How Plants Measure Their CO2 Uptake
08/26/2019 Plants face a dilemma in dry conditions: they have to seal themselves off to prevent losing too much water but this also limits their uptake of carbon dioxide. A sensory network assures that the plant strikes the right balance. When water is scarce, plants can close their pores to prevent losing too much water.

Poisonous grasses: new study provides reassurance
Poisonous grasses: new study provides reassurance
07/25/2019 Stories of mass poisoning incidents of livestock due to toxic grasses made headlines especially overseas. Animal ecologists from Würzburg have studied whether this hazard is also lurking on German pastures. "Dangerous Pastures: Deadly Grass Puts Horses at Risk" - Such dire warnings on the websites of horse owners and horse lovers may cause people to see their environment in a whole new light.

How climate change disrupts relationships
How climate change disrupts relationships
07/18/2019 Plants rely on bees for pollination; bees need plants to supply nectar and pollen. Scientists from the University of Würzburg have studied how climate change affects these mutualistic interactions.

Tracking down climate change with radar eyes
Tracking down climate change with radar eyes
"The Arctic is a hotspot of climate change," explains Prof. Florian Seitz of the German Geodetic Research Institute at the Technical University of Munich (TUM). "Due to rising temperatures, the glaciers of Greenland are receding. At the same time sea ice is melting. Every year, billions of liters of meltwater are released into the ocean." The enormous volumes of fresh water released in the Arctic not only raise the sea level, they also have the potential to change the system of global ocean currents - and thus, our climate.

New Findings on Early Bombardment of the Earth and Moon and Their Development
Freie Universität Researchers Contribute to International Study Published in Nature No 215/2019 from Jul 12, 2019 How did the Earth evolve from a fireball about 4.5 billion years ago to a habitable world? The key to this question lies in the early history of our planet, when the bombardment with cosmic bodies slowly declined.

The secret of mushroom colors
The secret of mushroom colors
In nature, specific colors and patterns normally serve a purpose: The eye-catching patterns of the fire salamander convey to its enemies that it is poisonous. Red cherries presumably attract birds that eat them and thus disperse their seed. Other animals such as chameleons use camouflage coloring to protect themselves from discovery by predators.

Scientists alarmed by bark beetle boom
Scientists alarmed by bark beetle boom
Bark beetles are currently responsible for killing an unprecedented number of trees in forests across Europe and North America. Researchers are therefore urging to step up research into bark beetles - also in view of climate change. "Bark beetles lay waste to forests" - "Climate change sends beetles into overdrive" - "Bark beetles: can the spruce be saved?": These newspaper headlines of the past weeks covered the explosive growth of bark beetle populations and its devastating impact on timberlands.

Bitcoin causing CO2 emissions comparable to Hamburg
Although Bitcoin is a virtual currency, the energy consumption associated with its use is very real. For a Bitcoin transfer to be executed and validated, a mathematical puzzle must be solved by an arbitrary computer in the global Bitcoin network. The network, which anyone can join, rewards the puzzle solvers in Bitcoin.

Microbial Systems Open a New Chapter in Biosphere Research
A New Study from Freie Universität Berlin in Cooperation with the University of Virginia No 139/2019 from May 21, 2019 In a recent study, biologists from Freie Universität Berlin and the University of Virginia (USA) examine ideas about closed ecological systems and how to further develop them. The goal of the study is to establish concepts that will make it possible to conduct experiments with self-sustaining ecosystems.

EUMETSAT, Japanese space agency to cooperate on greenhouse gas monitoring
EUMETSAT and the Japan Aerospace Exploration Agency (JAXA) today signed an agreement which will result in the agencies working closely together to monitor greenhouse gases in the Earth's atmosphere. Mr Kazuo Tachi, on behalf of the Direc tor General of JAXA's Space Technology Directorate 1 Ryoichi Imai, and EUMETSAT Director-General Alain Ratier signed the agreement at a ceremony at EUMETSAT's Darmstadt headquarters today.

Wax helps plants to survive in the desert
Wax helps plants to survive in the desert
04/26/2019 The leaves of date palms can heat up to temperatures around 50 degrees Celsius. They survive thanks to a unique wax mixture that is essential for the existence in the desert. In 1956, the Würzburg botanist Otto Ludwig Lange observed an unusual phenomenon in the Mauritanian desert in West Africa: he found plants whose leaves could heat up to 56 degrees Celsius.

New Pathways for Sustainable Agriculture
New Pathways for Sustainable Agriculture
Diversity beats monotony: a colourful patchwork of small, differently used plots can bring advantages to agriculture and nature. This is the result of a new study by the University of Würzburg. Hedges, flowering strips and other seminatural habitats provide food and nesting places for insects and birds in agricultural landscapes.

Mount Kilimanjaro: Ecosystems in Global Change
Mount Kilimanjaro: Ecosystems in Global Change
03/28/2019 Land use in tropical mountain regions leads to considerable changes of biodiversity and ecological functions. The intensity of such changes is greatly affected by the climate. 2019 marks the 250 th anniversary of Alexander von Humboldt. He was one of the first naturalists to document the distribution and adaptation of species on tropical mountains in the 19 th century.

Butterfly numbers down by two thirds
Butterfly numbers down by two thirds
Meadows adjacent to high-intensity agricultural areas are home to less than half the number of butterfly species than areas in nature preserves. The number of individuals is even down to one-third of that number. These are results of a research team led by Jan Christian Habel at the Technical University of Munich (TUM) and Thomas Schmitt at the Senckenberg Nature Research Society.

Public-sector research boosts cleantech start-ups
Cleantech start-ups in the USA that cooperate with government research agencies outperform their competitors both in terms of patents and funding. That is the conclusion of a study by the Technical University of Munich (TUM), the University of Maryland and the University of Cambridge. In the cleantech sector, where development processes can extend over many years, public-private partnerships could prove valuable in other countries, too.

National Climate Policy Pays Off
The efforts of developed economies to reduce their carbon dioxide (CO2) emissions by boosting the use of renewable energy sources and increasing energy efficiency are beginning to pay off. This is the result of a study conducted by an international team of researchers that includes scientists from Heidelberg.

Cool adaptations to the cold
Cool adaptations to the cold
02/25/2019 Icefish live in an environment that should be deadly for them. Scientists have now investigated how they still manage to exist there and what evolutionary adaptations they have had to undergo in order to do so. You really don't want to have to live there: In the Arctic Ocean around the South Pole, the water temperature is just below minus two degrees.

How plants learned to save water
How plants learned to save water
02/21/2019 Plants that can manage with less water could make agriculture more sustainable. This is why a research team at the University of Würzburg is investigating how plants control their water balance. Tiny pores on the leaves of plants, called stomata, have a huge influence on the state of our planet.

A Volcanic Binge And Its Frosty Hangover
A Volcanic Binge And Its Frosty Hangover
A major volcanic event could have triggered one of the largest glaciations in Earth's history - the Gaskiers glaciation, which turned the Earth into a giant snowball approximately 580 million years ago. Researchers from Heidelberg University and colleagues from Mexico have discovered remnants of such a large igneous province that resulted from vast lava flows.

How plants cope with iron deficiency: Botany
How plants cope with iron deficiency: Botany
Iron is an essential nutrient for plants, animals and also for humans. It is needed for a diverse range of metabolic processes, for example for photosynthesis and for respiration. If a person is lacking iron, this leads to a major negative impact on health. Millions of people around the globe suffer from iron deficiency each year.
