Some environmental issues polarize people, producing weary political stalemates of indecision and inaction. Others, however, grab hold of our most primeval instincts, causing us to reach deeply into our memories of childhood, and our first direct experiences with nature: the bumble bee nest we poked at with a stick; the man at the county fair with the bee(More)
Pollinators are essential to Pacific Northwest agriculture Commercially managed honey bees pol-­ linate a variety of crops in the Pacific North-­ west, including tree fruits, berries, cucurbits, and crops grown for seed. This activity is economically significant. In 2004, the value of bee-­pollinated crops in the region was approxi-­ mately $1.7 billion(More)

P ollinator conservation and rangelands don't seem like obvious bedfellows. In this era of sustainability, the connection between pollinator conservation and row crops or pollinator conservation and orchards is obvious. But pollinator conservation and rangelands? The reality is that pollinators are a key component of a healthy rangeland ecosystem. As Kevan(More)
The foraging patterns of Osmia cornifrons (Radoszkowski) (Megachilidae, Hymenoptera) were determined with an immunomarking method and correlated with fruit set in a commercial tart cherry orchard in Pennsylvania. Adults of O. cornifrons were self-marked with chicken egg-white protein powder from a dispenser nest box placed at the center of the study orchard(More)

pollination by animals is an essential ecosystem service. It is estimated that 60 to 80 percent of the world's 250,000 flowering plants depend on animals—mostly insects—for pollination (Kremen et al. 2007). Eighty-seven of the world's 124 most commonly cultivated crops are animal pollinated, and insect-pollinated forage plants such as alfalfa and clover(More)
