A key knowledge gap in classical biological control is to what extent insect agents evolve to
novel environments. The introduction of biological control agents to new photoperiod …

Predicting how organisms will respond to anthropogenic climate change and other human
impacts on the environment has become a key goal of ecological research, with the ultimate …

Reproductive barriers drive divergence by restricting gene flow between populations.
However, barriers are often semipermeable, allowing some gene flow between groups …

Sympatric speciation, the evolution of reproductive isolation between populations without
physical barriers to dispersal, is less likely than allopatric speciation due to the need to …

The sugar beet moth, Scrobipalpa ocellatella (Boyd), one of the most severe sugar beet
pests, causes quantitative and qualitative yield losses late in the autumn. Previously, it was …

In this paper we explore the conditions of entry-timing advantages in renewable natural
resource industries. Drawing from behavioral theory of the firm, we classify firms in two …

Many insects exhibit geographic variation in voltinism, the number of generations produced
per year. This includes high-latitude species in previously glaciated areas, implying …

Conditions in nature change with the seasons, necessitating seasonal adaptations that
synchronize the life cycles of organisms with their surroundings. Such regulatory …

Living organisms are constantly making decisions about how to optimize under variable and
often unpredictable environments. As ecologists, we are often interested in how these …

In temperate environments, organisms need to adapt to the seasonal cycle by synchronizing
the timing of their life cycle (phenology). Although this synchronization is paramount for their …
