Abstract:
... Generalist insect herbivores, those recorded as using numerous hosts (tens or even hundreds of species), are not well understood ecologically. We suggest ways to investigate the ecology of these species beyond the practice of accumulating host records. We present reasons why multiple host use by herbivorous insects needs to be quantified in the field, both locally and geographically, and also thro ...

Abstract:
... Diet specialisation drives life‐history adaptations and is an important factor determining the geographic distribution of species. Previous empirical studies have shown that diet specialists should compose the majority of species in a given location, and theory predicts that generalists should have higher geographic distribution range compared with specialists (the niche breadth‐range size hypothe ...

Hill stems was quantified in four locations containing healthy populations and in one location with populations threatened by non-native insect herbivores in order to determine the influence of reduced plant health on Eₛ. Minimal variation of Eₛ occurred among the four locations with healthy plants, and Eₛ ranged from 1.68 to 1.79 ...

Abstract:
... The transition to herbivory by insects is associated with distinct genomic signatures. Sequenced genomes of extant herbivore species reveal the result of these transitions, but in lieu of comparisons between herbivorous and non-herbivorous lineages that diverged recently, such datasets have shed less light on the evolutionary genomic processes involved in diet shifts to or from herbivory. Here, we ...

Abstract:
... Insect–plant interactions occur in several ways and have considerable environmental and ecological importance. Many feeding strategies have evolved among herbivorous insects, with host–herbivore systems likely being influenced by trophobionts with ants. We investigated how these interactions vary across elevation gradients by evaluating the structure of the herbivorous insect community and ants as ...

Preliminary field observations at our study site showed strong differences in the infestation level of four varieties of maize by wireworms. We raised and tested the hypothesis that these maize varieties have differential susceptibility/attraction to wirewo ...

Yet, to ascertain the role of natural selection on phenotypic differentiation between populations, it is necessary to discard other evolutionary process ...

While recent research revealed that aboveground insect herbivory generally impacts the outcome of PSFs, no study tested to what extent the intensity of herbivory affects the outcome. This, however, is essential to estimate the contribution of ...

Classic competition theory predicts that competition will increase with niche overlap and population density.
