urgent conservation priority in many regions. Understanding which butterfly species migrate …

Natural habitats are increasingly affected by anthropogenically driven environmental
changes resulting from habitat destruction, chemical and light pollution, and climate change …

Addressing population declines of migratory insects requires linking populations across
different portions of the annual cycle and understanding the effects of variation in weather …

Melanin is the most widespread pigment in organisms. Melanin-based coloration has been
repeatedly observed to be associated with the same traits and in the same direction in …

Background While global change research has greatly expanded in recent years, it remains
unclear how environmental change will impact the mobility of many organisms. Flight is an …

Background Selective pressures that occur during long-distance migration can influence
morphological traits across a range of taxa. In flying insects, selection should favour …

For many animals and insects that are experiencing dramatic population declines, the only
recourse for conservationists is captive rearing. To ensure success, reared individuals …

1. Many important insect pests undertake seasonal migrations at continental scales in
response to changes in resource quality and availability. The frequency and timing of these …

The environment shapes the evolution of secondary sexual traits by determining how their
costs and benefits vary across the landscape. Given the thermal properties of dark coloration …
