Abstract
Workshop to Explore Causes and Extent of Declines Among Native Invertebrate Pollinators: Detection, Evidence and Consequences Insects, particularly native bees, are the predominant and essential pollinators of many wild and agricultural plants in North America. For many flowering plants, they move pollen between plants while foraging, thereby contributing to: 1) fruit set and size, 2) seed production and viability, and 3) seedling vigor, while 4) enhancing genetic diversity of plant populations. Is this essential ecosystem service in jeopardy? It could be if human activities are causing widespread declines in pollinator abundance, or accelerated rates of extinction. Declining abundance would soon translate into less frequent flower visitation and abrupt or gradual diminution of seed and fruit production. Depauperate pollinator faunas offer less redundancy to buffer fruit and seed set against the inevitable and sometimes chaotic population swings of individual pollinator species, with repercussions for animal species and humans dependent on regular production of those plants and their seeds/fruits for food. This 3-day workshop will have two objectives. First, we will summarize the credible evidence for long-term human influences on native pollinating insects and the fruits of their pollination services at local and global scales. Second, we will evaluate the promise and practicality of strategies for filling gaps in that knowledge through studies employing 1) extant or readily obtained data sets (short-term research) and 2) long-term monitoring of inadvertent or purposeful experiments.
