D. Earl Green, C. Kenneth Dodd Jr.
2007, Herpetological Conservation and Biology (2) 43-47
Amphibian populations and species are declining or disappearing from many regions throughout the world (Stuart et al. 2004). No single cause has been demonstrated, although a number of emerging infectious diseases have been suggested as primary etiologic agents (Berger et al. 1998; Daszak et al. 2003; Lips et al. 2006)....
InSAR imaging of volcanic deformation over cloud-prone areas - Aleutian islands
Zhong Lu
2007, Photogrammetric Engineering and Remote Sensing (73) 245-257
Interferometric synthetic aperture radar (INSAR) is capable of measuring ground-surface deformation with centimeter-tosubcentimeter precision and spatial resolution of tens-of meters over a relatively large region. With its global coverage and all-weather imaging capability, INSAR is an important technique for measuring ground-surface deformation of volcanoes over cloud-prone and rainy regions such...

Zhong Lu, Oh-Ig Kwoun, R.P. Rykhus
2007, Photogrammetric Engineering and Remote Sensing (73) 217-221
Very simply, interferometric synthetic aperture radar (InSAR) involves the use of two or more synthetic aperture radar (SAR) images of the same area to extract landscape topography and its deformation patterns. A SAR system transmits electromagnetic waves at a wavelength that can range from a few millimeters to tens of...

2007, Aquatic Invasions (2) 197-214
We report on the occurrence and possible establishment of a non-native cichlid fish in a brackish-water system in the lower Chao Phraya River delta region, Thailand. Although, the possibility of some degree of introgressive hybridization can not be ruled out, Thailand specimens agree best with Mayan Cichlid “Cichlasoma” urophthalmus (Günther 1862). Our...
