Differences in blister beetle consumption between male and female great bustards.

†χ2 test.††GLM test with Poisson distribution.†††Significance values cannot be determined because there was only one female stomach with a blister beetle.Occurrence (%) is the percentage of faeces or stomachs where blister beetles were found. Abundance is the number (n) of blister beetles per excrement and stomach. Weighted abundance (n/g) takes into account the larger size of male faeces and stomachs, and expresses the number of blister beetles per gram of faeces and stomach content (n/g). Biomass is expressed as dry weight (g) of blister beetles per excrement and stomach, and weighted biomass is defined as dry weight (g) of blister beetle per gram of excrement and stomach content (g/g) (n = 212 faeces and n = 17 stomach contents). Data are means ± SD.Differences in blister beetle consumption between male and female great bustards.
