How to design safe and sustainable chemicals
How to design safe and sustainable chemicals
With many human-made chemicals, problems regarding public health and the environment become apparent only years after their widespread use. A team of researchers from the University of Amsterdam and Utrecht University now propose a way to change that. In an article in the journal 'Chemosphere' they present a method for (re)designing safe and sustainable chemicals.

Newly discovered African 'climate seesaw' drove human evolution
Newly discovered African ’climate seesaw’ drove human evolution
A scientific consortium has found that ancient El Niño-like weather patterns were the primary drivers of environmental change in sub-Saharan Africa over the last 620 thousand years - the critical timeframe for the evolution of our species. The group, including Dr William Gosling from the University of Amsterdam, found that these ancient weather patterns had more profound impacts in sub-Saharan Africa than glacial-interglacial cycles more commonly linked to human evolution.

Differences between juveniles and adults determine resilience of complex ecological communities
A new study shows that differences between juvenile and adult individuals are crucial for the stability of complex ecological communities. These findings, now published in the scientific journal Proceeding of the National Academy of Sciences by Prof. André de Roos from the University of Amsterdam, provides important information about the dynamics and functioning of diverse ecological communities.

Measuring bird migration above ARTIS as part of a demonstration site
Measuring bird migration above ARTIS as part of a demonstration site
Researchers of the University of Amsterdam have installed a BirdScan radar at the elephant enclosure in ARTIS Amsterdam Royal Zoo to record bird migration. This BirdScan radar is part of the first site of the national research project ARISE that has the ultimate aim to monitor biodiversity in the Netherlands.

How sponges dine in a marine desert
How sponges dine in a marine desert
Marine biologists have been able to visualize for the first time how tropical sponges and their symbiotic bacteria work together to consume and recycle organic food. The research led by Meggie Hudspith and Jasper de Goeij from the University of Amsterdam, was a collaborative project with colleagues from the Australian Universities of Sydney, Queensland and Western Australia, and the research institute Carmabi on Curaçao, and is now published in the scientific journal Microbiome.

Eutrophication turns aquatic omnivores into vegetarians
Eutrophication turns aquatic omnivores into vegetarians
The feeding behaviour of several invertebrate animals in aquatic food webs is drastically changed by increasing inputs of nitrogen and phosphorus into surface waters. This is demonstrated in a new study by researchers from the University of Amsterdam and Wageningen Environmental Research, that is now published in the scientific journal Ecology.

Extinction of mammals affects the future of tropical palms
Extinction of mammals affects the future of tropical palms
The loss of large mammalian frugivores as seed dispersers in tropical ecosystems will have severe consequences for many rainforest plants. This is the conclusion from a study using empirical data and simulations of fruit-eating mammals and palms, both iconic elements of tropical forests worldwide. The authors of the study, including UvA researchers Jun Ying Lim and W. Daniel Kissling, have published their results in the scientific journal Nature Communications.

A new approach to the restoration of ecosystem complexity
A new approach to the restoration of ecosystem complexity
How can we best protect the Earth's biodiversity and ecosystems? Long-term ecosystem restoration strategies should be looking more closely at the complexity of ecosystems, including species interactions and evolution, says an international group of scientists, including UvA soil ecologist Elly Morriën, in the renowned scientific journal Nature Ecology & Evolution.

Ecological changes with minor effect lead to delayed evolutionary regime shifts
Small changes in the environmental conditions of biological communities that have only minor immediate effects, may, after a substantial delay, cause dramatic shifts in these communities by triggering evolutionary processes. This is the main conclusion of research from theoretical ecologists Catalina Chaparro-Pedraza and André de Roos at the University of Amsterdam.
