Table 1 Relationships between the Simpson index of chemical diversity and MHC-DRB diversity in ring-tailed lemurs across seasons, with significant relationships indicated in bold
Sex | Compounds in Simpson index | Explanatory variable | Z value | P value | Effect |
|---|---|---|---|---|---|
Male | Overall Diversity | Season | 1.64 | 0.10 | Simpson diversity index increases with increasing MHC diversity, regardless of the season |
MHCsupertype | 2.17 | 0.03 | |||
Season x MHCsupertype | − 0.89 | 0.37 | |||
Female | Overall Diversity | Season | 0.86 | 0.390 | No relationship between Simpson index and season or MHC diversity in females |
MHCsupertype | 0.24 | 0.810 | |||
Season x MHCsupertype | −0.98 | 0.330 | |||
Female | Fatty Acid Diversity | Season | 2.24 | 0.025 | Simpson index for FAs is negatively correlated with MHC diversity, but only in the nonbreeding season |
MHCsupertype | −0.38 | 0.703 | |||
Season x MHCsupertype | −3.75 | 0.001 | |||
Female | Fatty Acid Ester Diversity | Season | 1.02 | 0.310 | No relationship between female Simpson index of FAEs and season or MHC diversity in females |
MHCallele | −0.34 | 0.740 | |||
Season x MHCallele | −1.64 | 0.100 |
