Pretty sure these were pulled as highlights from the "References" section, but I can't guarantee that beyond confirming they are listed there. The article does add some interpretive commentary quoting experts. The best TL;DR I could grab from the previous discussion: >MrBuddyCasino https://news.ycombinator.com/item?id=15503474 https://news.ycombinator.com/item?id=15503474 Der Spiegel discusses issues in the methodology of the data collection. The intervals over the years weren't uniform, data was collected by volunteers/hobbyists and they did not measure the dry mass weight. There are differing opinions whether or not those issues have relevance. SZ gives some details on suspected causes. Neither climate change (warmer weather should yield more insects, not less) nor changes in plant diversity can explain the observed effects alone. Main suspects: - agricultural fertilizers, especially nitrogen - pesticides, especially neonicotinoides
