Fires are ubiquitous features of many terrestrial ecosystems and can greatly impact the structure and evolution of plant communities. However, much less is known about how fire history impacts higher trophic levels. Using detailed records on the hist

The ball-gall fly Eurosta solidaginis is considered a classic example of host-race formation in herbivorous insects, with host-associated races evolving at least twice, including the well-known pair on Solidago altissima and S. gigantea. Yet E. solid

Worldwide, humans are altering the fire regimes (fire‐return intervals, severity, seasonality) of fire‐prone ecosystems, fragmenting natural landscapes, and altering climates. Efforts to restore fire regimes in natural areas are usually guided by

Reproductive isolation and speciation in herbivorous insects may be accomplished via shifts between host-plant resources: either plant species or plant organs. The intimate association between gall-inducing insects and their host plants makes them pa

Plant populations frequently maintain submaximal levels of resistance to natural enemies, even in the presence of substantial genetic variation for resistance. Identifying constraints on the evolution of increased resistance has been a major goal of

The reproduction and ecology of the narrow endemic and Florida endangered shrub Hypericum edisonianum (Edison's St. John's Wort) was investigated through field and greenhouse studies. Hypericum edisonianum exhibits a number of traits common to rare a
