Variable General Info
Bees nesting ?Comment:Beginning at 1900 the evening before bee and floral sampling, fifteen 0.36 m2 ground emergence tents (BugDorm BT2006, Taichung, Taiwan) were installed to capture nesting bees at each plot (Sardinas & Kremen, 2014; Sardinas et al., 2016). Tents were installed after dusk when female bees return to the nest after foraging. They were secured with stakes and soil on flaps to prevent overturning and limit insect escape, and kill jars were filled with soapy water. The proportion of tents capturing bees at a plot is herein referred to as “nesting rate”. |
