Do Land Management Changes Have Effects on Climate as Large as Land Cover Changes?
See details
(Latest Thinking), 10 mins
The study presented in this video evaluates data from observational towers, satellite pictures and other published data to compare the impact of land-cover change and land management change on climate. The results show that land management change within the same vegetation (e.g., harvesting a formerly untouched fo...

Do Plants Emit Volatile Compounds When Defending Themselves Against Herbivores?
See details
(Latest Thinking), 11 mins
Plants have at least two ways of defending themselves against herbivores. They can do so directly by producing toxins or compounds that are anti-digestive, or they can indirectly defend themselves by emitting volatile compounds that attract predators and parasitoids of the herbivores. MEREDITH SCHUMANN investigate...

How Can Waste Be Converted Into a Source of Carbon for the Production of Chemicals?
See details
(Latest Thinking), 12 mins
Currently, the petrochemical industry uses fossil fuels as the source of carbon for the production of many things, including plastics. This is problematic because carbon dioxide adds to climate change and, in addition, fossil fuels are running out. Therefore, LARGUS ANGENENT and his research group are looking for...

How Can We Speed Up the Discovery of Biodiversity on Earth?
See details
(Latest Thinking), 11 mins
Humans may be sharing earth with up to twenty million species of macroscopic life, let alone microscopic life. Today, about 1.8 million species have been described and currently, we discover about 18,000 species per year, which means it would take us thousands of years to describe them all. This is why JOHANNES VO...

How Do Belowground Components Contribute to the Healthy Functioning of Ecological Systems?
See details
(Latest Thinking), 8 mins
Being easier to observe, the aboveground components of ecological systems tend to be considered of predominant importance. In this video, STEFAN SCHEU explains the extent to which the healthy functioning of these systems is dependent on what happens underground. With visual observation impossible, Scheu employs is...

How Do Climate Change Related Natural Disasters Potentially Increase the Risk of Armed Conflicts?
See details
(Latest Thinking), 10 mins
There is an extensive discussion about the connections between climate change related disasters and armed conflicts like civil wars. JONATHAN DONGES explains in this video how the research team looked at this relationship in more detail. Their new approach connects natural disasters with large economic effects, po...

How Do Forest Trees Defend Themselves Against Insects Under Natural Conditions and Is This Process Affected by Forest Management?
See details
(Latest Thinking), 14 mins
When plants are being attacked by herbivore insects, they protect themselves by emitting volatiles that attract enemies of the insects. This has already been well investigated in greenhouse settings and on smaller plants but very little research has been done under natural conditions and on trees. In this video, S...

How Do Plant Genomes Develop Different Phenotypes Depending on Their Environment?
See details
(Latest Thinking), 16 mins
Once a plant has germinated in a particular location, it cannot change it anymore. This means its growth depends on its location with its particular context, such as soil, herbivores, or sunlight levels. Therefore plants have evolved sophisticated signal transduction systems that allow them to perceive the outside...

How Do Plants Regulate Their Behavior Based on Their Carbohydrate Resources?
See details
(Latest Thinking), 14 mins
It has been known since the 1980s that sugars are central to the growth of plants. High levels of carbohydrates enable the plant to assimilate nitrogen to increase amino acid synthesis which then enables them to make proteins more quickly which, in turn, allows the plant to grow faster. It is still unclear, howeve...

How Does the Interplay of Genes, Environment, and Development Affect the Biological Diversity of a Species?
See details
(Latest Thinking), 7 mins
Plants, animals, and fungi show a huge diversity regarding form and phenotype: the observable characteristics of an organism. The research presented in this video uses the model of a particular roundworm to investigate how the phenotype is changed by the environment; this is known as phenotypic plasticity. RALF SO...
