Ecology is a subdiscipline of biology that examines the interrelationships of organisms and their environment.
Environmental protection and nature conservation are elements of ecology. Because environmental awareness has been on the rise since the middle of the 20th century, the term ecology is frequently used in the same breath as environmental protection andnature conservation. There is a demarcation line however. Ecology describes the relationship between living beings and the environment, while environmental protection and nature conservation involve measures aimed at preserving the environment. Although ecology research is a broad field, it can be broken down into three main subdisciplines :
At a high level, ecology involves the propagation and frequency of organisms. Where do they come from? What type of organism did they originate from? How many are there? And where do they appear? The goal of ecological analyses is providing answers to these questions. Biotic and abiotic environmental factors that can influence the environment are also part any ecological analysis. What makes ecological research so difficult is the complexity of the biological systems. Individual observations serve less as focal points and more as general conclusions produced from mathematics, statistics or experiments. A vital part of ecology is reducing complex structures to simple conclusions based on natural science.
While ecology takes a holistic approach, environmental protectionmainly involves measures aimed at preserving the basic existence of all living beings. This calls for maintaining a healthy ecosystem. For this reason, nature conservation plays a leading role in ecology as well as in environmental protection. A basic element of environmental protection involves rectifying human-induced damage to the environment. As a result, this requires observing not only the individual parts, but the overall relationships between the parts as well, The term environmental protection first gained attention in the 1970s. One of the primary goals of environmental protection is preserving the human ecosystem. Although preservation of the human ecosystem is a major aspect of environmental protection, technical solutions are still frequently employed. Environmental protection can be divided into several disciplines:
From a global point of view,environmental protection is always related to one of these subdisciplines.
Apart from ecology and environmental protection, an important area is nature conservation. Although environmental protection and nature conservation typically complement one another, there are certain exceptions. In the field of ecology, renewable raw materials such as wood are points of conflict between nature conservation and environmental protection. While nature conservation demands that trees be preserved as long as possible and eventually turned into deadwood for the ecosystem of a variety of animals, environmental protection views wood as a sustainable energy source and raw material. Environmental protection also seeks to avoid the radical deforesting of lands and forests. Within nature conservation there are also initiatives that oppose wind power and small hydropower systems. Under the context of nature conservation, the idea is to impact nature as little as possible. Nature conservation is also a local issue. Nature conservation frequently involves single locations. As it pertains to ecology, nature conservation examines ways to preserve and reestablish a balanced ecosystem. Nature conservation strives toward sustainable human use of our natural environment. Nature conservation is a goal of government and is established in Article 20a of the German constitution. Nature conservation also means the protection of animals and homelands. Many individuals also view nature conservation as important, because they understand the dramatic consequences if society is not actively engaged in nature conservation.
This complex theme deals primarily with interactions between organisms and the environmental factors that impact them, but to a greater extent between individual inanimate environmental factors.

Algae farming is widespread in China. The macroalgae Laminaria is mainly used for food in China but its bioactive ingredients are also used, for example, in cosmetics, dietary supplements or as an additive to animal food. The industrial processing of Laminaria produces wastewater with a salinity of around 20 percent. A team led by Dr. Laurenz Thomsen, Professor of Geosciences at Jacobs University, and Postdoc Dr. Song Wang wants to clean this high-salinity wastewater with microalgal technology.
The cooperation partner is Shandong Haizhibao Ocean Science and Technology Co Ltd. Haizhibao is currently the biggest provider for macroalgae in China, with...14.05.2019 | Read more

Loss and fragmentation of habitat are among the main reasons why biodiversity is decreasing in many places worldwide. Now, a research team with participation of the German Centre for Integrative Biodiversity Research (iDiv) and Martin Luther University Halle-Wittenberg (MLU) has established that the destruction of habitat causes double damage to biodiversity; if habitat patches disappear, not only do the species living there become extinct, but species richness in neighbouring patches also declines. The reason for this additional species loss is the large physical distances between the remaining habitat patches, the researchers write in the journal Ecology Letters.
For their study, scientists from the iDiv research centre, the Uni Halle and the WasserCluster Lunz research centre in Austria used long-term data on the...02.04.2019 | Read more
On behalf of the EU Commission, Fraunhofer ISI explored what contribution individual technologies can make to decarbonizing industry and how to support them. The study shows that it is possible to cut emissions by 95% by 2050. However, this requires innovative carbon-neutral technologies and comprehensive technological change – especially in basic materials industries. In addition, Fraunhofer ISI examined the role of an innovation fund to aid the market diffusion of these technologies using revenue from the EU emissions trading system.
Industry is responsible for about 20 percent of the EU-wide greenhouse gas emissions. It will have to reduce its emissions to almost zero by 2050 to meet the...25.03.2019 | Read more
There are roughly five times as many recreational fishers as commercial fishers throughout the world. And yet, the needs and peculiarities of these 220 million recreational fishers have largely been ignored in international fisheries and conservation policy. This gives rise to conflicts and loss of social welfare, and is not conducive to the sustainable management of fish stocks. An international team of fisheries scientists, economists, sociologists and ecologists led by Robert Arlinghaus from the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) has now presented a five-point plan to bring about reform.
Compared to commercial fishing, the social, economic and ecological importance of recreational fisheries is greatly underestimated in public and political...20.03.2019 | Read more
Vegetation biomass on grasslands increases in response to elevated carbon dioxide levels, but less than expected. Vegetation on grasslands with a wet spring season has the greatest increase. This has been demonstrated in a new study published in the scientific journal Nature Plants.

Carbon nanotubes (CNTs) are valuable for a wide variety of applications. Made of graphene sheets rolled into tubes 10,000 times smaller than a human hair, CNTs have an exceptional strength-to-mass ratio and excellent thermal and electrical properties. These features make them ideal for a range of applications, including supercapacitors, interconnects, adhesives, particle trapping and structural color.
New research reveals even more potential for CNTs: as a coating, they can both repel and hold water in place, a useful property for applications like printing,...
If you've ever tried to put several really strong, small cube magnets right next to each other on a magnetic board, you'll know that you just can't do it. What happens is that the magnets always arrange themselves in a column sticking out vertically from the magnetic board. Moreover, it's almost impossible to join several rows of these magnets together to form a flat surface. That's because magnets are dipolar. Equal poles repel each other, with the north pole of one magnet always attaching itself to the south pole of another and vice versa. This explains why they form a column with all the magnets aligned the same way.
Now, scientists at ETH Zurich have managed to create magnetic building blocks in the shape of cubes that - for the first time ever - can be joined together to...

In two experiments performed at the free-electron laser FLASH in Hamburg a cooperation led by physicists from the Heidelberg Max Planck Institute for Nuclear physics (MPIK) demonstrated strongly-driven nonlinear interaction of ultrashort extreme-ultraviolet (XUV) laser pulses with atoms and ions. The powerful excitation of an electron pair in helium was found to compete with the ultrafast decay, which temporarily may even lead to population inversion. Resonant transitions in doubly charged neon ions were shifted in energy, and observed by XUV-XUV pump-probe transient absorption spectroscopy.
An international team led by physicists from the MPIK reports on new results for efficient two-electron excitations in helium driven by strong and ultrashort...
