Soil Preferences Of Nicrophorus Beetles And The Effects Of Compaction On Burying Behavior, Kelly A. Willemssens
Soil Preferences Of Nicrophorus Beetles And The Effects Of Compaction On Burying Behavior, Kelly A. Willemssens
School of Natural Resources: Dissertations, Theses, and Student Research
The American burying beetle, Nicrophorus americanus Olivier was declared federally endangered in 1989 and many efforts to prevent this species from going extinct are ongoing. The Nicrophorus beetles bury small carcasses for reproductive purposes. They also reside in the soil during times of daily and seasonal inactivity. To better understand why N. americanus is in decline, the importance of soil texture, moisture, vegetation, gravel, the burial depth, and the effect of compaction on their burying behavior was examined.
All tested species preferred moist soils with N. orbicollis having a significant preference for wet (pN. marginatus had a significant preference for …

I. FIRE-RESILIENCY OF A NORTH AMERICAN ARTEMISIA (ASTERACEAE) SHRUB: IMPLICATIONS FOR RESTORATION OF A CRITICAL ECOSYSTEM PROCESS. Conclusions: Unlike most North American Artemisia shrub species, our research suggests that A. filifolia is highly resilient to the effects of fire. Therefore, use of prescribed fires for the restoration and maintenance of ecosystem processes and properties is appropriate in A. filifolia shrublands of the southern Great Plains in North America.
II. RESTORATION OF THE FIRE-GRAZING INTERACTION IN ARTEMISIA FILIFOLIA SHRUBLAND OF THE SOUTHERN GREAT PLAINS, NORTH AMERICA. Synthesis and applications. Vegetation structure in Artemisia filifolia shrublands of our study were readily altered …
