Managing Monarch butterfly overwintering groves: making room among the eucalyptus

Proper management and conservation of the coastal California overwintering sites used by western Monarch butterflies (Danaus plexippus L.) is critical for continued use of these sites by monarchs. Many management efforts are currently concentrating on eucalyptus-only sites because of the prevailing notion that monarchs prefer eucalyptus over native tree species. Yet, whether a preference exists or not has never been tested. Herein, we test the “eucalyptus preference” hypothesis with data from five overwintering sites comprised of blue gum eucalyptus (Eucalyptus globulus) and at least one other native tree …

Comparison Of Small Mammal Communities In Ephemeral Wetlands And Wet Meadows During Drought, Brian M. Zinke

Master's Theses

Ephemeral wetlands are characterized by a cyclical hydropattern, ranging from complete inundation to a total absence of surface water. This cycle between wet and dry phases is necessary for the flora of ephemeral wetlands to perpetuate. However, little research has been done to study the response of the non-avian fauna to these cycles, particularly during the dry phase. I live trapped small mammals by using Sherman live traps and conducted vegetation surveys monthly (May–August in 2012 and May–July in 2013) in the ephemeral wetlands and the surrounding wet meadows of the Cheyenne Bottoms basin in central Kansas. Drought occurred both …
