The importance of sympatric speciation–the evolution of reproductive isolation between
codistributed conspecific individuals–in generating biodiversity is highly controversial …

Contemporary global change is altering ecosystems at an unprecedented pace and scale.
This critical period is a crisis for biodiversity, but the perturbations caused by global …

Host race formation, the establishment of new populations using novel resources, is a major
hypothesized mechanism of ecological speciation, especially in plant‐feeding insects. The …

Many organisms enter a dormant state in their life cycle to deal with predictable changes in
environments over the course of a year. The timing of dormancy is therefore a key seasonal …

Diapause, a form of insect dormancy, generally facilitates overwintering by increasing cold
tolerance and decreasing energy drain at high temperatures via metabolic rate suppression …

Bactrocera minax is a major citrus pest distributed in China, Bhutan and India. The long
pupal diapause duration of this fly is a major bottleneck for artificial rearing and underlying …

Simple Summary Some species of insect herbivores can feed on a wide variety of plant
species. Over evolutionary time, insect herbivores can associate preferentially with different …

Understanding and characterizing how insects tolerate low temperatures is important for
predicting their overwintering survival and subsequent geographic spread. This study …

Competition for resources often contributes strongly to defining an organism's ecological
niche. Endogenous biological rhythms are important adaptations to the temporal dimension …

The duration of dormancy regulates seasonal timing in many organisms and may be
modulated by day length and temperature. Though photoperiodic modulation has been well …
