Fledging success is a poor indicator of the effects of bird blow flies on ovenbird survival
Sean M. Peterson, Henry M. Streby, Paul M. Kapfer
2009, Condor (111) 193-197
Infestations of bird blow flies (Protocalliphora spp. and Trypocalliphora braueri) have various negative effects on the condition of nestling birds. In the absence of other stressors such as inclement weather, however, infestation alone rarely reduces fledging success. Previous studies have documented effects of blow flies on nestling condition and fledging success. Without...

Classification of CO2 Geologic Storage: Resource and Capacity
S.M. Frailey, R.J. Finley
2009, Conference Paper, Energy Procedia
The use of the term capacity to describe possible geologic storage implies a realistic or likely volume of CO2 to be sequestered. Poor data quantity and quality may lead to very high uncertainty in the storage estimate. Use of the term "storage resource" alleviates the implied certainty of the term...
