Fossils provide the only direct evidence of how mass extinctions unfold. But the fossil record of insects is very different from the fossil records of other groups. A new review in the Annals of the Entomological Society of America explores what we can learn about past insect extinctions from their fossils.
A study of lone star ticks in the forested Missouri Ozarks found that nymphs and adults were more abundant in valleys and on north-facing hills than in other areas. Meanwhile, nymphs appeared less often in the areas of greater temperature variability, while adults were less prevalent with increased elevation.
After a 100-year flood struck south central Oklahoma in 2015, a study of the insects, arthropods, and other invertebrates in the area revealed striking declines of most invertebrates in the local ecosystem, a result that researchers say illustrates the hidden impacts of natural disasters.
