“…Egyptian spiny mice (A. cahirinus), the principal host of P. chephrenis, lack fur on their pinnae and they do not have their characteristic spines around their head, so fleas are readily observed feeding in these areas. Finally, most individual rodents are right-pawed (Agulova et al, 2010;Kutlu et al, 2012;Ribeiro-Carvalho et al, 2010;Ribeiro et al, 2014) and begin their grooming sequence at the right side of their head (Berridge, 1990). Thus, a speculative but logical sequence of events related to flea avoidance of host grooming could explain directional asymmetry favouring the sinistral side in P. chephrenis.…”

Morphological asymmetry is widely used to measure developmental instability and higher levels of asymmetry often correlate with decreased mating success, increased inbreeding, increased stress and decreased habitat quality. We studied asymmetry and relationships between asymmetry and host identity in two flea species, host generalist Xenopsylla ramesis and host specialist Parapulex chephrenis, and asked: (1) what the level of asymmetry was in their femurs and tibiae; (2) which type of asymmetry predominates; and (3) whether fleas that fed on host species distantly related to their principal host species produced offspring that exhibited greater asymmetry compared with offspring of fleas that fed on their principal host species. We found fluctuating asymmetry in femurs and tibiae of X. ramesis and in the tibiae of P. chephrenis as well as significantly left-handed directional asymmetry in the femurs of P. chephrenis. Host species identity significantly impacted asymmetry in leg segments of P. chephrenis but not in those of X. ramesis. Offspring asymmetry increased when mother fleas fed on a host that was distantly related to the principal host. Fleas parasitizing multiple host species might compensate for developmental instability when utilizing a novel host species; therefore, host-switching events in host-specific parasites could be constrained by the relatedness between a novel and a principal host species.

Directional asymmetry (DA) was demonstrated for teeth morphotypes, adrenal and kidney weights, and for length of the hind paw as well. DA may be formed both at early and later development stages and is not dependent on environmental factors and population density dynamics. Although each trait has its own dynamics DA in ontogeny, usually DA increases in the period of sexual maturation. Uncoordinated development of the sides in this period seems to associate with an increase in intensity of developmental processes. Our study argues that sexual dimorphism of continuous traits appears at the later developmental stages. This finding is consistent with Geodakian's evolutionary theory of sex. Evolutionary significance of the DA is to increase both short-term individual fitness and long-term population adaptive capacity.Developmental approach to the study of morphological and functional asymmetries in animals opens new possibilities for the study of evolutionary processes. of Morphological Traits During Postnatal Ontogeny… weighed with a torsion balance to a precision of 1 mg. It is very important to reduce measurement errors in asymmetry studies, since the difference between the bilateral traits is usually small (Palmer, Strobeck, 1986;Palmer, 1994;Merilä, Björklund, 1995). For this reason, the lengths of the external morphometric traits, the front and hind paw, were measured 2-3 times with a caliper 0.1 mm to reduce measurement errors. If the difference between the measures was larger than 0.3 mm, measurements were repeated. The median, i.e. the non-parametric point estimate, was chosen.The relative age of voles was estimated according to the degree of physiological maturation and the data on body length and mass by the standard methods (Bashenina, 1953; Larina, Lapshov, 1974). According to this, all voles were divided into four age groups: immature, juveniles and subadults, and mature, adults and senescents.
