Title Carbon and nitrogen in roots and leaves of crops and wild gourds in the family Cucurbitaceae
Downloaded 1 time
Description The percent nitrogen and carbon content of leaves, flowers and roots were measured on a Carlo Erba CHN analyzer. Samples were analyzed in triplicate on two young but fully formed leaves and on roots from each plant to calculate percent nitrogen and carbon. Readme file contains species names and abbreviations.

Title Cucurbitacins in roots, flowers and leaves of crops and wild gourds in the family Cucurbitaceae
Description The concentrations of the cucurbitacins are expressed as µg cucurbitacin/g dry tissue sample based on HPLC analysis. Trace amounts are indicated as (++) for prominent peaks too small to be considered for calculations. (+) indicates peaks smaller than (++). (–) indicates peaks smaller than (+). To quantify these data a standard curve, based on peak area, was fashioned for cucurbitacins B and D. The Cucurbitacin B slope 5.00E+06 and intercept 8.00E+06. The Cucurbitacin D slope 8000000.00 and intercept -9000000.00. Readme file contains species names and abbreviations.

Title Herbivory 2005
Description Field Experiment measuring herbivory on crops and wild gourds in the Cucurbitaceae. DB = # dead beetles, LB = # live beetles, all beetles are Acalymma vittatum; cotyledon damaged = Yes or No. Damage was assessed on the four youngest fully expanded leaves at each census Lf1 is oldest, Lf4 is youngest. Scores are 0-4 indicating 0%, 1-25%, 25-50%, 50-75%, or 75-100% leaf area removed. Readme file contains species names and abbreviations.

Title Herbivory 2006
Description Field experiment measuring herbivory on crops and wild gourds in the Cucurbitaceae. Dam Lf: Damaged Leaf, B = # dead beetles, LB = # live beetles, all beetles are Acalymma vittatum. Damage is assessed on the four youngest fully expanded leaves at each census: Lf1 is oldest, Lf4 is youngest. Damage is measured in % area removed Damage in %: 0, 1, 5, 10, 25, 50, 75, 100 "." = leaves gone. cot damage: 100 = dead leaves still there. Readme file contains species names and abbreviations.

Title Pollinator Observation of crops and wild gourds in Cucurbitaceae
Description Data from field experiments in 2005 and 2006. At the observation start, flower sex (Female or Male), # ants (not identified), # beetles (Acalymma vittatum) was recorded. In the data sheet each flower visitor has its own row. Pollinators are identified as: smbee (= small bee, not identified), sqb (= squash bee, Peponapis pruinosa), lgBB and smBB (large and small bumble bees, not ID'ed beyond Bombus; B. impatiens and B. bimaculatus are very common here) hb (= honey bee, Apis cerana) and a few other miscellaneous bees, not ID'ed. Time, is the time in seconds of the pollinator visit. 'total approaches,' are times that insects got close to the flower but did not land. These could be considered 'rejections' in that the insect comes close enough to assess the flower but does not alight. Columns following total approaches are broken down by visitor and abbreviated "app". There is one row of approach data per observation. Readme file contains species names and abbreviations.
