Description:
Using historic data sets, we quantified the degree to which global change over 120 years disrupted plant-pollinator interactions in a temperate forest understory community in Illinois, USA. We found degradation of interaction network structure and function and extirpation of 50% of bee species. Network changes can be attributed to shifts in forb and bee phenologies resulting in temporal mismatches, nonrandom species extinctions, and loss of spatial co-occurrences between extant species in modified landscapes. Quantity and quality of pollination services have declined through time. The historic network showed flexibility in response to disturbance; however, our data suggest that networks will be less resilient to future changes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Burkle, Laura A -- Marlin, John C -- Knight, Tiffany M -- New York, N.Y. -- Science. 2013 Mar 29;339(6127):1611-5. doi: 10.1126/science.1232728.
