A study of the McKenzie River floodplains, terraces and glacial
outwash plains was undertaken to classify and describe the vegetation
and soils of a previously little studied synecological unit.
During the summer of 1971, 54 analytic vegetation and soil
plots (stands) were studied. Cover and frequency of all trees, shrubs,...
Laboratory experiments and simulated field conditions were
utilized to gain a better understanding of the ecology of the clouded
salamander.
Animals collected in western Oregon were utilized for studies
in habitat selection, where it was shown that there was a significant
pattern of selection of litter types (rock, bark, and...
Osteosarcoma (OSA) is a primary malignant bone tumor sarcoma that occurs in dogs as well as people and has aggressive biologic behavior with devastating consequences. Because of the similarities in morphology and prognosis, OSA in dogs represents an effective model for the equivalent disease in humans. Mesenchymal stem cells (MSCs)...
The interaction of polylysine with DNA may be divided into two
separate phenomena: the primary interaction involved in formation of
a well-defined complex, and secondary interactions leading to aggregation
of these complexes. Most studies on the interaction of polylysine
with DNA have used techniques which measure properties of
the aggregated...
Thais emarginata is a gastropod which inhabits the midlittoral
zone of the intertidal region. Oxygen consumption of high-level and
low-level organisms was determined at various seasons of the year
over an experimental temperature range of 5 to 20° C.
No significant difference in respiratory rate between separate
populations of high-level...
Summary
1. Woody plant encroachment of grasslands is occurring globally, with profound ecological
consequences. Attempts to restore herbaceous dominance may fail if the woody state is resilient
or if intervention leads to an alternate, undesirable state. Restoration outcomes often
hinge on biotic interactions – particularly on priority effects that inhibit...
