Research Interests: 

My research focuses on how human activities affect terrestrial invertebrate communities and the ecosystem services they provide. My students and I work in temperate grasslands, riparian areas, and agroecosystems. Primary topics of current interest include the following:

Native Bees:

  • Effects of riparian restoration and native and domestic ungulate grazing on native bees and their floral resources
  • Interaction of invasive annual grass invasions, fire, and livestock grazing on grassland bee communities, their floral resources, and their nesting habitat
  • Effect of grassland restoration on native bee communities
  • Understanding how climate change and riparian condition interact to influence native bees in riparian areas
  • Managing field margins and uncultivated areas in agroecosystems in the interior Columbia Basin to enhance crop pollination
  • Vertebrate wildlife-pollinator interactions

Food Webs:

  • The effects of river and upland management and climate change on riparian food webs and reciprocal subsidies with aquatic systems (visit our EPA STAR project page - Balancing Ecosystem Services in Semi-Arid Agricultural Lands in an Uncertain Future)
  • Livestock effects on grassland food webs involving invertebrates
  • Effects of riparian condition on the abundance, diversity and community composition of terrestrial invertebrates, and how these effects are translated through food webs involving fish and wildlife in adjacent streams and terrestrial uplands
  • The influence of riparian condition on the density of pest and beneficial invertebrates in agricultural lands next to riparian areas 

Specialties: Native Pollinators, Riparian Ecology, Ecosystem Services, Terrestrial Invertebrate Community Ecology

    Seeing Climate Change in Bugs and Salmon

    There are many ways to measure climate change. In northeast Oregon, scientists are investigating aquatic insects and how land management around waterways could potentially help or hinder salmon, which spawn in the streams.

    Megachilid Bees in the Pacific Northwest: An Introduction

    This publication is an introduction to the Megachilidae family of bees found in the Pacific Northwest. It highlights the characteristics of two important members of this family: leafcutting bees and mason bees, both of which play a major role in pollinating both common garden plants and crops.
