A recent paper published in Current Biology by Mekonnen and Hoekstra (2018) shows that freshwater ecosystems are subject to water acidification and that this can affect the predator-prey interactions in freshwater communities. Another paper published in Water Resources Research reports a substantial global increase of phosphorus levels in major lakes and streams.
The year of 2017 marked the 100th anniversary of the publication of The Biology of Dragonflies (1917) by R.J. Tillyard; a goldmine of information and a masterpiece that played a great role in founding our current knowledge of the life of odonates. A review published in Austral Entomology commemorates this important event and writes about the author, his scientific endeavor, and the impact of his book.
In a recent paper published in Hydrobiologia, Kalkman et al. report analyses of the diversity, distribution, and status of odonates (dragonflies and damselflies) in Europe, using the Atlas of the European dragonflies and damselflies.
