Contradicting theories of primatologists, a study led by Brazilian scientists shows that in a habitat with high hunting pressure, the risk of predation influences the habits of these monkeys more than the availability of food. They spend less time in areas they perceive as 'more dangerous' even if plant biomass and invertebrates are more abundant there.
It's a treasure trove of data: the global vegetation database 'sPlotOpen' is now freely accessible. It contains balanced, representative data on vegetation from 114 countries and from all climate zones on Earth. The database was compiled by an international team of researchers led by Martin Luther University Halle-Wittenberg (MLU), the German Centre for Integrative Biodiversity Research (iDiv) and the French National Centre for Scientific Research (CNRS).
Wetter conditions in Sub-Saharan and North Africa at certain times of year can result in hundreds of times more Painted Lady butterflies making the 14,000km round trip to Europe. Findings improve understanding of how insects move to other countries, including pests that destroy crops and disease-carrying species like mosquitoes.
When a University of Michigan-led research team reported last year that North American migratory birds have been getting smaller over the past four decades and that their wings have gotten a bit longer, the scientists wondered if they were seeing the fingerprint of earlier spring migrations.
The traditional approach that ecologists use to experimentally study the effects of species loss on an ecosystem likely underestimates the impact of real-world species loss, such as that caused by climate change, according to a new study in PNAS.
Sperm size varies dramatically among different animal species. But why is sperm size so variable when they share the same job -- to fertilize eggs? In a new article published in Nature Ecology and Evolution, researchers from Stockholm University show that animal sperm evolution become supercharged only when sperm swim inside females.
Lake Victoria, which came under the spotlight in 2004 by the documentary "Darwin's nightmare", is not only suffering from the introduction and commercialisation of the Nile perch. A study lead researchers from the University of Liège (Belgium) has highlighted other worrying phenomena, particularly climatic ones, which have an equally important impact on the quality of the lake's waters.
New study by the ICTA-UAB shows that residents and visitors highlight the natural and biodiversity values of the Llobregat Delta, in Barcelona.
Over the past 35 years, there have been large shifts in the distributions of many dragonfly species in Germany. Those of standing water habitats have declined, probably due to loss of habitat. Running-water species and warm-adapted species have benefited from improved water quality and warmer temperatures. This was found by a team of researchers led by the German Centre for Integrative Biodiversity Research (iDiv). The study highlights the importance of citizen science and natural history societies for long-term data collection.
A new article, published as a Perspective in the journal Conservation Science and Practice, introduces a rapid assessment framework that can be used as a guide to make conservation and nature-based solutions more robust to future climate.
