Purpose of the Study
In most liberal arts colleges, the majority of students enrolled
are primarily interested in a liberal education. To meet the requirements
of its students, several colleges have introduced a relatively
new program in the sciences; this program is the integrated
science course. This study attempts to...
Wild turkey (Meleagris gallopavo) ecology has been examined within its native range, but knowledge of extralimital populations of Rio Grande wild turkeys (M. g. intermedia) is lacking. I investigated habitat use, characteristics of activity sites, home
ranges and movements, productivity, and survival of Rio Grande turkey hens from 1989
through...
The atmospheric trace element abundances associated with slash
burning have been measured by instrumental neutron activation analysis
(INAA). On site ground level samples were collected during the slash
burning season using high volume samplers and a cascade impactor. In
addition to the air samples, soil, wood and ashed wood samples...
The historical function of fire in sagebrush steppe has been altered by 19th century overgrazing, active fire suppression, annual grass invasion and encroachment of woody species. The significance of fire to these systems is known, but research on long-term fire effects are limited. The Sheep Rock management unit of the...
Using techniques that permit the direct observation of
fetuses in vivo, prenatal behavioral development was
compared among four species in the rodent family Muridae:
the Norway rat (Rattus norvegicus), Mongolian gerbil
(Meriones unguiculatus), cotton rat (Sigmodon hispidus), and
spiny mouse (Acomys cahirinus). Rattus and Meriones bear
altricial offspring, as do...
Investigations were made in the field, greenhouse, growth
chamber, and laboratory to: (a) observe the general activity of N-
(phosphonomethyl)glycine (glyphosate); (b) determine the extent of its
interaction with certain s-triazine herbicides; and (c) find an explanation
for such an interaction.
Greenhouse and growth chamber studies substantiated other
observations that...
