Songbirds who make the arduous flight from their nesting sites in northern boreal forests to warm, southern climates in the winter may be rewarded for their journey with greater genetic diversity, according to a University of Michigan study. Greater genetic diversity could help a species survive better, but that gain is threatened by habitat loss…
The theme for this year’s International Day for Biological Diversity on May 22 emphasizes the interconnectedness of nature and human wellbeing, and the importance of biodiversity for achieving sustainable development goals. One thing is certain. Despite all our technological advances we are undeniably and totally dependent on a healthy and vibrant ecosystem for our food…
A novel analysis suggests more than 3,500 animal species are threatened by climate change and also sheds light on huge gaps in fully understanding the risk to the animal kingdom. The study was published today in BioScience. “We’re at the start of an existential crisis for the Earth’s wild animals,” said Oregon State University’s William…
Plants that reproduce exclusively by self-pollination arise from populations with extremely low diversity to begin with. The Kobe University research not only adds a facet to possible evolutionary strategies, but also lends weight to Darwin’s suspicion that this strategy might be a path to extinction. Charles Darwin once remarked, “It is hardly an exaggeration to…
When a plant species spreads beyond its habitat, it is usually seen as a threat to native flora and fauna. But what happens when that same species is struggling to survive in its original range? A new study published in New Phytologist and led by researchers at the German Centre for Integrative Biodiversity Research (iDiv),…
In a new study, researchers at the University of Würzburg are investigating the interaction of major global change drivers on insects. The number and diversity of insects is declining worldwide. Some studies suggest that their biomass has almost halved since the 1970s. Among the main reasons for this are habitat loss – for example through…
The Florida Museum of Natural History has partnered with 35 herbarium collections across the United States to create a web portal for ferns. Wait! Hear me out. You’re probably thinking, “Ferns? The plants with the curly leaves that grow in shady places? Why should I care?” I’m glad you asked. Ferns — and a related…
The number of species does not increase evenly when going from local ecosystems to continental scales – a phenomenon ecologists have recognised for decades. Now, an international team of scientists, including researchers from the German Centre for Integrative Biodiversity Research (iDiv) and the Martin Luther University Halle-Wittenberg (MLU), has developed a new theory to explain…
Increasing urban vegetation by 30 per cent could save over one-third of all heat related deaths, saving up to 1.16 million lives globally from 2000 to 2019 according to a 20-year modelling study of the impact of increasing greenness in more than 11,000 urban areas. The study, led by Monash University Professor Yuming Guo and…
Insects are disappearing at an alarming rate worldwide, but why? Agricultural intensification tops the list of proposed reasons, but there are many other, interconnected drivers that have an impact, according to new research led by Binghamton University, State University of New York. Research on insect decline has surged in recent years, sparked by an alarming…
