Activity Of A Dipodomys Ordii Population Using Recapture Methods, James R. Garcia
Activity Of A Dipodomys Ordii Population Using Recapture Methods, James R. Garcia
Theses and Dissertations
Activity curves for Dipodomys ordii were developed from data obtained from a study utilizing an electrically monitored trapping grid. The curves for non-perturbated populations showed an initial post-dusk peak, followed by increasing activity and a large pre-dawn peak; but after ten dominant animals had been removed, the largest activity peak was post-dusk. Differences in activity patterns were not found among sex, age or reproductive classes. Rising ambient temperatures, falling barometric pressures, winds over 3.2 km/hr and the absence of the moon depressed capture numbers; while increasing humidity (relative and absolute), decreasing soil temperatures at 20 and 40 cm below ground …

Theses and Dissertations
Structural aberrations induced in chromosomes by irradiation have been described and classified in great detail (Bender, 1969; Arena, 1971). According to Bender (1969), these aberrations appear after exposure to ionizing irradiation following cell division, or persist unmodified and unrecognizable in interphase cells for many years. In either case, these aberrations persist and can be seen years after radiation exposure.
