Growth and development of temperate and tropical passerines of the New World : a life history perspective

Creator:: Austin-Bythell, Suzanne H.
Abstract:: I studied developmental rates in a suite of temperate and tropical passerine bird species from the New World to test the hypothesis that tropical passerines exhibit slower patterns of growth and development than temperate birds. I also investigated how the expression of several developmental rates varied with life history traits...

Evaluation of stream temperature spatial variation using distributed temperature sensing

Creator:: O'Donnell, Tara
Abstract:: Water temperature in rivers and streams is an important factor for aquatic ecosystem health. Measurement of stream temperature has traditionally been accomplished by point temperature measurements, continuous point temperature loggers, and more recently, airborne remote sensing techniques such as Forward-Looking Infrared Radar (FLIR) or Thermal Infrared Radiometry. While each of...
