Novel host plant unmasks heritable variation in plant preference within an insect population
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
Mammalian herbivores restrict the altitudinal range limits of three alpine grass species
Though rarely experimentally tested, biotic interactions have long been hypothesized to limit low-elevation range boundaries of species. We tested the effects of herbivory on three alpine-restricted plant species by transplanting plants below (novel), at the edge (limit), or in the center (core) of
Arthropod abundance censused on the host plant Ligusticum porteri near Gothic, CO.
The objective of this study is to understand how climate cues affect the abundance and phenology of aphids and the arthropods with which they interact. These data were collected in 20 populations of the host plant (Ligusticum porteri) along an elevation gradient near Gothic, CO, USA. We randomly-sel
Data for 'Weak latitudinal gradients in insect herbivory for dominant rangeland grasses of North America'
Patterns of insect herbivory may follow predictable geographical gradients, with greater herbivory at low latitudes. However, biogeographic studies of insect herbivory often do not account for multiple abiotic factors (e.g. precipitation, soil nutrients) that could underlie gradients. We tested for
Data for Context-dependent biotic interactions control plant abundance across altitudinal environmental gradients, 2014, 2016, Colorado, USA
Many biotic interactions influence community structure, yet most distribution models for plants have focused on plant competition or used only abiotic variables to predict plant abundance. Furthermore, biotic interactions are commonly context-dependent across abiotic gradients. For example, plant-pl
Lupine alkaloid data
This is an Excel file containing one sheet with 23 columns. Each row represents the data and metadata for a single tissue sample from a single individual. Column 1: specifies the species; Column 2: species the individual ID (ID numbers repeat across species); Column 3: specifies the tissue; Column 4
