Abstract:

We briefly review the effects of climate (particularly drought and hurricanes), insect outbreaks, and fire on populations of migrant birds. An important feature of all of these natural disturbances is that they occur over a variety of spatial and temporal scales, thus precluding any simple generalization of their effects or of methods for mitigating those effects. We recognize that (1) natural catastrophic phenomena will inevitably occur; (2) an ecosystem will consist of a mosaic of patches that reflects the recurrence time and spatial extent of these disturbances; and (3) after some period, a disturbed patch will recover. We therefore recommend that an appropriate goal is to have as a management unit a sufficiently large area (not necessarily contiguous) to contain some minimum number of patches that will be in a recovered state. This "incorporation" of disturbance is facilitated by increasing the size of the management unit or altering the size and/or frequency of disturbance. We suggest that the most pressing research need is to determine the characteristic scale of disturbances that are important and relevant to the species and habitats that we have an interest in preserving.

Notes:

NOTE: 1) Conference Paper Pub Type should include Proceedings Name with the Conference Name. 2) Needs a field for Publisher Location (Fort Collins, CO, for this doc). 3) Needs also a place for Conference dates (I've inserted after Conference/Proc name in this case).
