Global changes are severely affecting pollinator insect communities worldwide, resulting in
repeated patterns of species extirpations and extinctions. Whilst negative population trends …

Theory generally predicts that host specialisation and dispersal should evolve jointly.
Indeed, many models predict that specialists should be poor dispersers to avoid landing on …

For highly specialized insect herbivores, plant chemical defenses are often co-opted as cues
for oviposition and sequestration. In such interactions, can plants evolve novel defenses …

Dispersal is a central life history trait that affects the ecological and evolutionary dynamics of
populations and communities. The recent use of experimental evolution for the study of …

Migratory animals exhibit traits that allow them to exploit seasonally variable habitats. In
environments where migration is no longer beneficial, such as oceanic islands, migration …

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 …

In a variety of aposematic species, the conspicuousness of an individual's warning signal
and the quantity of its chemical defence are positively correlated. This apparent honest …

Monarch butterflies are a species of conservation priority due to declining overwintering
populations in both eastern and western North America. Declines in western overwintering …

Highlights•Insect range shifts vary widely in rates and consequences.•Incorporating eco-
evolutionary dynamics is essential to understand this variation.•Temporal and spatial …

Abstract Monarch butterflies (Danaus plexippus)(Lepidoptera Danaidae Danaus plexippus
(Linnaeus)) are an iconic species of conservation concern due to declines in the …
