Stoichiometry and infectious disease: Linking chemical elements and parasitic interactions

A growing body of work has shown that parasites’ growth and reproduction can be influenced by the food quality available to their hosts. Consumers, including parasites, require a balanced diet to grow. Unlike many consumers, however, parasites are beholden to the diet quality presented to them by th

The effects of climate change and biodiversity loss on mutualisms

The abiotic environment drives species abundances and distributions both directly and indirectly through effects on multi-trophic species interactions. However, few studies have documented the individual and combined consequences of these direct and indirect effects. We studied an ant-tended aphid a

From grain to floodplain: Evaluating heterogeneity of floodplain hydrostratigraphy using sedimentology, geophysics, and remote sensing

Floodplain stratigraphy, a major structural element of alluvial aquifers, is a fundamental component of floodplain heterogeneity, hydraulic conductivity, and connectivity. Watershed-scale hydrological models often simplify floodplains by modeling them as largely homogeneous, which inherently overloo

Advanced phenology of higher trophic levels shifts aphid host plant preferences and performance

King of the hill? How biotic interactions affect biogeographical pattern and species responses to climate change

As climate has warmed, many species have moved up mountains as physiological limits to their distributions have ameliorated. These distribution shifts are creating novel communities, begging the question: What happens to species at the tops of mountains as potential antagonists encroach upwards? The

Adaptation and diversification of bluebells <i>Mertensia</i> spp., Boranginaceae

Flowering phenology marks the transition from vegetative growth to reproduction and exposes plants to seasonally varying selective environments during flowering. Life-history trade- offs between time and size at reproduction suggest that early-flowering species should generally be smaller than late-

Floral reward strategies, visitor behavior, and plant reproductive outcomes

Many plants that bear hidden or recessed floral nectar experience nectar robbing, the removal of nectar by a floral visitor through holes pierced in the corolla. Although robbing can reduce plant reproductive success, many studies fail to find such effects. We outline three mechanistic hypotheses th

How vulnerable are pollen-specialist solitary bees to temperature-mediated shifts in the timing of food availability?

Snowmelt affects aphid (<i>Aphis asclepladis</i>) populations through soil moisture and host plant phenology

Plant-insect interactions are ecologically important relationships that are greatly affected by climate change. Previous research concerning an aphid species (Aphis asclepiadis) and its host plant (Ligusticum porteri) has shown that aphid abundances correlate significantly with snowmelt date in the
