Prevailing methods of measuring diet breadth of phytophagous insects are not consistent between studies and generally rely on counts of a variety of higher plant taxa (e.g. genera, families, orders).

Aims: Long-term climate stability is hypothesized to drive the emergence of species assemblages with large species age differences due to the accumulation of relict species and relatively newly arisen ...

A North Carolina State University study published online this week in Proceedings of the National Academy of Sciences shows that examining an insect's "family tree" might help predict a "cousin" ...

Just as bird watchers may use binoculars to add to their species lists, scientists interested in bird evolution may use computational tools to clarify avian lineages. Indeed, such tools have enabled ...

A first-of-its-kind report shows more than 100 native species of trees in the lower 48 states are facing the threat of extinction due to invasive insects, diseases and climate change. A sweeping ...

Bizarre-looking bugs known as scale insects may be tiny but they can take down an oak tree. Considered pests, the creatures tend to flock to cities where they weaken, and in some cases kill, trees by ...
