Trees in cities have many benefits but can increase ozone during heat waves.

But scientists have found a counterintuitive effect of urban vegetation: During heat waves, it can increase air pollution levels and the formation

Dam in Sabiñanigo town, Spain. There are currently in excess of 70,000 large dams worldwide. With the continuing construction of new dams, more than 90 per cent of the world’s rivers will be fragmented by at least one dam within the next 15 years.

Far from being the pristine ‘deserted island’ that people might imagine of such a remote place, Henderson Island is a shocking but typical example of how plastic debris is affecting the environment on a global scale, say the researchers.

In a series of paired interactions, the most competitive fungus was Phlebiopsis flavidoalba, which is the top fungus in the upper right corner of the photo. One of the least competitive was Armillaria tabescens (not shown), and one of the strongly-defensive species that deadlocked in most of its competitions was Phellinus hartigii, which is the
