Fluctuating Asymmetry and Developmental Instability of a Stag Beetle, Cyclommatus mniszechi (Coleoptera, Lucanidae)
Abstract
Developmental homeostasis is a mechanism that can maintain the development of organisms toward expected phenotypes. Developmental homeostasis of phenotypic traits can be maintained by two processes, including canalization and developmental stability (DS). Canalization reduces among-individual phenotypic variation, while DS reduces within-individual variation in traits. Fluctuating asymmetry (FA) of phenotypic traits is regarded as the outcome of developmental instability (DI) of an organism under random environmental or genetic noise. Nevertheless, the relationships among DS, canalization and FA, and the relative importance of canalization and DS in maintaining developmental homeostasis of a trait are still unclear. Møller and Pomiankowski (1993) proposed a hypothesis concerning the pattern of phenotypic variation and FA under different modes of selection. It predicted that under directional natural selection, the FA of a phenotypic trait increases. In contrast, stabilizing selection decreases the FA of a phenotypic trait. The FA has a positive relationship with trait size under directional selection, while the extreme sizes of a trait has the largest FA under stabilizing selection. The exaggerated mandibles of stag beetles are secondary sexual traits, used as weapons in territorial fights and considered to be under strong directional sexual selection. I used a stag beetle species, Cyclommatus mniszechi, as the study organism to investigate the relationships among DS, canalization and FA and to study the patterns of FA in a various morphological traits presumably under different selection schemes. I divided individuals from the same families of stag beetles into high and low nutritional treatments, representing habitats with low and higher environmental noises, respectively. I compared the FA of mandibles and other morphological traits and predicted that the mandible, which is under directional selection, should have greater FA than traits under stabilizing selection. I used mixed model ANOVAs to analyze the pattern of FA. The preliminary results indicated that the mandibles of both high and low nutritional treatments are directional asymmetry (DA). The thorax, elytra and femur of foreleg showed FA. However, the head width of low nutritional treatments showed a pattern of DA, while that of high nutritional treatment is FA. The mandibles of 3rd instar larvae presented a pattern of DA. Mandibles of larvae and adult males show DA that means mandibles is under functional constraint. The measurement of head traits needs to be reconsidered.

Weapon shape difference predict fighting style？A case study of three different stag beetles
Abstract
The divergent fighting contexts hypothesis suggests that the difference of where and/or how species use their weapons shapes the diversification of animal weapon. However, the relationships between weapon shape, fighting behavior and the evolution of weapon diversity are still not clear. The study of dimorphic stag beetle Cyclommatus mniszechi showed that male morphs have different proportions of fighting behavior elements in size-matched contests. The previous studies of fighting behavior of four stag beetle species with different mandible shapes showed similar behavior elements. This study will focus on three stag beetles, C. mniszechi, Dorcus yamadai, and Lamprima adolphinae, which have different mandible shapes (curve down, flat and curve up, respectively). The relationship between shape difference and the fighting behaviors of these three species will be examined. We expect that the fighting styles of the three species should be lift (C. mniszechi), push (D. yamadai), and pry (L. adolphinae).
