Biodiversity hypothesis called into question
Biodiversity hypothesis called into question
The trade-off between gleaners and exploiters does not explain the diversity of biological species in the way that scientists expected. Our understanding of biodiversity has to change. Aquatic organisms - and terrestrial ones - that do best when there is lots of food also do best when there is very little .

Better catalysts for a sustainable bioeconomy
Better catalysts for a sustainable bioeconomy
Researchers at the Paul Scherrer Institute PSI and from ETH Zurich want to make so-called zeolites more efficient. Today, these compounds are already indispensable additives in the chemical industry and have been used as catalysts in oil refineries since the 1960s. Now, , the researchers advocate paying more attention to the classic zeolites.

Worldwide loss of phosphorus due to soil erosion quantified for the first time
Worldwide loss of phosphorus due to soil erosion quantified for the first time
Phosphorus is essential for agriculture, yet this important plant nutrient is increasingly being lost from soils around the world. The primary cause is soil erosion, reports an international research team led by the University of Basel. The study Communications shows which continents and regions are most strongly affected.

Transistor-integrated cooling for a more powerful chip
Transistor-integrated cooling for a more powerful chip
Researchers have created a single chip that combines a transistor and micro-fluidic cooling system. Managing the heat generated in electronics is a huge problem, especially with the constant push to reduce the size and pack as many transistors as possible in the same chip. The whole problem is how to manage such high heat fluxes efficiently.

Amphipods: a miraculous increase in biodiversity
Amphipods: a miraculous increase in biodiversity
Until recently, researchers assumed that Switzerland had around 20 native species of amphipods. Now, a project by the Swiss Federal Institute of Aquatic Science and Technology (Eawag) and the University of Zurich has revealed that there are actually more than 40. It is always worth taking a closer look, because we can only protect the things that we know exist.

Nationwide decline of threatened plant species in Switzerland
Nationwide decline of threatened plant species in Switzerland
The Swiss Flora is one of the richest and most diverse in Europe. However, more than 700 plant species are considered to be threatened. In a nationwide project over 400 volunteer botanists revisited known populations of all threatened and rare plant species in Switzerland and recorded their presence or absence.

A difficult year for forests, fields and meadows
A difficult year for forests, fields and meadows
The warm, dry summer of 2018 has left clear traces in various ecosystems. ETH Zurich researchers have found that if the climate continues to warm up, higher altitudes can also expect negative consequences in the future. It was - once again - an unusually hot year: in 2018, large parts of Europe were beset by an extremely hot and dry summer.

Protecting estuarine cities from rising sea levels
Protecting estuarine cities from rising sea levels
As climate change raises sea levels, estuarine cities are facing up to the dual threat of flooding and significant erosion. Research by a joint team from EPFL and the UNSW Sydney sheds new light on the hydrodynamic forces at play and paves the way for preventive strategies. Almost 60% of the global population lives near an estuary, and the list of estuarine cities features 21 of the world's 30 biggest urban centers, including New York and Tokyo.

Mini power plants from coated blue-green algae
Mini power plants from coated blue-green algae
Blue-green algae are among the oldest living creatures on Earth and have perfected the use of sunlight over billions of years. Empa scientists have now equipped these humble unicellular organisms with semiconductor coatings to create mini power plants, which supply biofuels and are photocatalytically active in sunlight.

Explosive diversification explained by network analysis
Explosive diversification explained by network analysis
Using genomic analyses of 100 cichlid species, scientists from Eawag and the University Bern, together with co-workers in Australia, the UK, Tanzania, Uganda and the US, have investigated the striking variation observed in cichlid fish speciation rates. Their findings show that exchanges of genetic variants between existing species dramatically accelerate the development of new species - given favourable ecological conditions.

Climate change and land use are accelerating soil erosion by water
Climate change and land use are accelerating soil erosion by water
Soil loss due to water runoff could increase greatly around the world over the next 50 years due to climate change and intensive land cultivation. This was the conclusion of an international team of researchers led by the University of Basel, which published the results from its model calculation in the scientific journal PNAS.

Anthropogenic CO2 increase is unprecedented
Anthropogenic CO2 increase is unprecedented
Even in earlier warm periods there were pulse-like releases of CO2 to the atmosphere. Today's anthropogenic CO2 rise, however, is more than six times larger and almost ten times faster than previous jumps in the CO2 concentration. This is the conclusion reached by a European research team led by the University of Bern.

Even small-scale solutions are affordable
Even small-scale solutions are affordable
How should Europe organise its renewable energy supply network - on a continental, national or regional level? It's a controversial issue. A Swiss-German research team has analysed the costs and technical feasibility of supply networks of various sizes. The European Union aims to achieve climate neutrality by 2050, and is relying largely on renewable electricity to reach this goal.

Restoration helps forests recover faster
Restoration helps forests recover faster
Actively restored forests recover above ground biomass faster than areas left to regenerate naturally after being logged, according to a long-term study on Borneo lowland rainforest led by the University of Dundee, Aberdeen and ETH Zurich.  The rainforests of Southeast Asia are among the fastest declining tropical ecosystems worldwide.

New Guinea Has the World's Richest Island Flora
New Guinea Has the World’s Richest Island Flora
New Guinea is the most floristically diverse island in the world, an international collaboration led by the University of Zurich has shown. The study presents a list of almost 14,000 plant species, compiled from online catalogues and verified by plant experts. The results are invaluable for research and conservation, and also underline the importance of expert knowledge in the digital era.

Predicting the Biodiversity of Rivers
Predicting the Biodiversity of Rivers
Biodiversity and thus the state of river ecosystems can now be predicted by combining environmental DNA with hydrological methods, researchers from the University of Zurich and Eawag have found. Using the river Thur as an example, the approach allows areas requiring conservation to be identified in order to initiate protective measures.

New map for radioactive soil contamination in Western Europe
New map for radioactive soil contamination in Western Europe
An international consortium of scientists has refined the map of caesium and plutonium radionuclide concentrations in soils in Switzerland and several neighbouring countries. Using an archive of European soil samples, the team led by Katrin Meusburger from the University of Basel, now at the WSL research institute, was able to trace the sources of radioactive fallout between 1960 and 2009.

Bird Diversity in the Swiss Alps in Decline
Bird Diversity in the Swiss Alps in Decline
The diversity of bird communities in the Swiss Alps is declining more and more, a joint study of the University of Zurich and the Swiss Ornithological Institute has found. An analysis of data from the past two decades has revealed a loss of functional and compositional diversity in Alpine bird communities.

Counting wheat heads for more ecology
Counting wheat heads for more ecology
To Achim Walter it's clear: the budding artificial intelligence will decisively advance agroecology. But before we can harvest the fruits of AI, computers still have a lot to learn. Over-fertilised fields, compacted soils, greenhouse gases and insect death - the list of problems in agroecology is both old and long.
