Questionnaire data, butterfly images and analysis code

This dataset contains the raw data of questionnaire named “Original data”
under the file
“Questionnaire_data__butterfly_wing_color_brightness_and_contrast.xlsx”,
that is the responses of local Dai people to the twenty questions
(Questions were indexed as the abbreviation of the categories from BK1 to
AK5. See the second column on sheet“proportion”). Original data was used
to do Kaiser-Meyer-Olkin (KMO) and Bartlett’s Test of Sphericity in SPSS
17.0, and Confirmatory factory analysis (CFA) in SPSS Amos Graphics (see
supplementary materials in Yang et al, “Biased local ecological knowledge
of butterfly diversity provided by the ethnic minority in Southwest
China's biodiversity hotspot"). The file named
“butterfly_images.rar” is the digital images of butterfly which were used
to measure the wingspan, wing color brightness and contrast. These data
were devoted to analyses the divergency between the butterflies recognised
or not by local Dai people stored in the xlsx file named “Wing color
brightness data”, “Wing color contrast data” and “Wing span data”. CSV
Files named “Ak1 to HI2” are the response of local Dai people to the
questionnaire. These files were used to do cumulative link mixed models
(CLMM) to test whether gender and age affect response patterns of the
individual questions. Relevant R code to CLMM was named as “CLMM. R”.
There questionnaire data were also used to do chi_square test (see detail
in supplementary materials in Yang et al, “Biased local ecological
knowledge of butterfly diversity provided by the ethnic minority in
Southwest China’s biodiversity hotspot”), relevant R code to chi-square
was named as “Chi-square”. The data related to demographic difference and
proportion of local respondents, the results of CLMM and Chi-square tests
were also stored in the
“Questionnaire_data__butterfly_wing_color_brightness_and_contrast.xlsx”.
Main results: 1) over 70% of them generally agreed with the importance of
butterfly conservation, but a large proportion of respondents did not
agree that they know about ecological and cultural significance of
butterfly conservation. 2) gender and age biases for the issues related to
cultural significance of butterflies and the causes of butterfly declines.
3) A total of 23 respondents said that they were “knowledgeable” about
local butterflies and selected 45 and 15 species as “familiar” and
“declining”, respectively. These species were, however, taxonomically
(i.e., none of Lycaenidae and Hesperiidae species were selected) and
morphologically biased (larger and more colorful butterfly species).
