Changing phenological cues can lead to trophic mismatch for plants and herbivores, and this often shifts herbivore feeding to plant stages of lower quality. Temperature can also mediate how herbivores respond to plant quality, leading to temperature-by-phenology interactions. We examined how both te

Interactions between a native plant species and its pollinators, herbivores, or microbiome can be affected by the presence of non-native plant species. Non-native plant species are altering plant-pollinator interactions, yet we know little about how these non-native species influence natural selecti

Introductions of novel plant species can disturb the historical resource environment of herbivorous insects, resulting in strong selection to either adopt or exclude the novel host. However, an adaptive response depends on heritable genetic variation for preference or performance within the targeted

Individual plants can modify the microenvironment within their spatial neighborhood. However, the consequences of microenvironment modification for demography and species interactions remain unclear at the community scale. In a study of co-occurring alpine plants, we (1) determined the extent of spe

Climate in subalpine meadows of the Rocky growing season drought conditions. Manipulating Mountains can be characterized by an early (fore- the strength of the foresummer drought by watering summer) drought that occurs after snowmelt (May) revealed that the timing of growing season pre- and lasts un

Here we review next-generation questions in the study of plant–pollinator interactions mediated by floral volatiles, and the potential for renewed collaboration between biologists and chemists in answering such questions.

Debate about control of interaction strength among species is fueled by variation in environmental contexts affecting food webs. We used extensive surveys and two field experiments to test the individual and interactive influences of variation in the assemblages and associated traits of grazers as s

“Pollination syndromes” are specific combinations of floral traits that are proposed to evolve convergently across angiosperm lineages in response to different types of animal pollinators. In spite of their long history, pollination syndromes have not been tested adequately–they rarely have been exa

Overall, male bumble bees are common and capable pollinators of G. parryi and in some years and sites could be more important than workers, and animal sexes may differ in their pollinator performance in other systems.

Movement uses resources that may otherwise be allocated to somatic maintenance or reproduction. How does increased energy expenditure affect resource allocation? Using the butterfly Speyeria mormonia, we tested whether experimentally increased flight affects fecundity, lifespan or flight capacity. W

New interactions with non-native species can alter selection pressures on native species. Here, we examined the effect of the spatial distribution of a non-native species, a factor that determines ecological and evolutionary outcomes but that is poorly understood, particularly on a fine scale. Speci

The ability to inhibit Bacillus cereus decreased in extracts from plants harvested from high light environments, which follows plant defense theory, and harvest sustainability in L. porteri is equivocal among the light environments examined in this study, although some medicinal properties vary.

SignificanceThe evolution of herbivory in animals is rare but has resulted in major adaptive radiations. Its rarity suggests that there are barriers to colonization of plants. Behavioral adaptations, involving host plant finding, are likely the first to evolve during the transition to herbivory. A r
