Osmia ribifloris temperature experiment, lipid content and body size responses

These data represent linear body size and fat (lipid) content responses of adult Osmia ribifloris bees to experimental temperature conditions. The experimental temperature treatments represent previous, cooler conditions (cooling), future warming conditions (warming) and current temperature conditions (control). This field experiment was conducted in the Santa Catalina Mountains outside of Tucson, Arizona, USA. Each row of the dataset represents the responses of an individual bee emerging from a nest. Emergence_date = the date on which the bee was observed emerging from the nest; treatment = the experimental temperature treatment; exp_block = the experimental block the nest was part of (this information combined with treatment information represents a unique nest box identification); hole_num = the nest number within each nest box; sex = the sex of the bee (male or female); id = an identification letter for each bee that emerged from the same nest; it_distance = the intertegular distance measured in millimeters for each individual bee (a measure of linear body size); mass_before_lipid_extraction_mg = the dry mass of the bee measured in milligrams before lipid extraction; mass_after_lipid_extraction_mg = the dry mass of the bee measured in milligrams after lipid extraction; lipid_content_mg = the lipid content of the bee measured in milligrams (this is the difference between the before and after mass measurements); lipid_percent = the proportion of the adult bee's body mass that is represented by lipids (i.e., lipid mass divided by the initial dry weight of the adult bee); lipid_test_box_id = a color code that represents where the individual bee was kept during lipid extraction; lipid_test_box_location = a location code for the specific location of the individual bee during the lipid extraction; lipid_trial = the lipid assay number (not all bees were processed at the same time); sample = a sample identification number; lipid_analysis_start = the date and time when each lipid extraction assay began.
