Captive breeding reveals larval performance and adult body size differences between two geographical populations of the stag beetle Aegus chelifer chelifer (Coleoptera: Lucanidae)

다국어 초록 (Multilingual Abstract)

Stag beetles usually have great intraspecific variation in their body sizes, which can be affected by both environmental and genetic factors. However, direct studies on wild-caught specimens may be insufficient to clarify such variation due to the confounding effects of ecological variance in natural habitats. To evaluate this, the stag beetle Aegus chelifer chelifer MacLeay, 1819 was collected from within two localities (Bangkok metropolitan area and Chanthaburi province) in Thailand and then reared under the same condition to investigate the differences in morphological characteristics between the wild-caught and captive-bred beetles and between the two geographical populations. Narrow-sense heritabilities (h2) of the observed traits in adults were not significant.
Variation in the body size of captive-bred specimens was less than in the wild-caught specimens and the overlap of the body size variation between the two populations was lower in the captive-bred beetles. The Chanthaburi population had a significantly larger body size than the Bangkok population. Allometric slopes and intercepts were also significantly different between the two geographic populations. Captive-bred larvae showed similar relative growth rates, but male larvae from the Chanthaburi population had a longer feeding period, and so a larger adult body size, than those from the Bangkok population. The differences between the two populations could be explained by adaptation through larval performances and body size in order to respond to their habitats
