Age‐specific effect of heterozygosity on survival in alpine marmots, Marmota marmota

et al. 2009

The fitness consequences of heterozygosity and the mechanisms underpinning them are still highly controversial. Using capture-mark-recapture models, we investigated the effects of individual heterozygosity, measured at 16 microsatellite markers, on age-dependent survival and access to dominance in a socially monogamous mammalian species, the alpine marmot. We found a positive correlation between standardized multilocus heterozygosity and juvenile survival. However, there was no correlation between standardized multilocus heterozygosity and either survival of older individuals or access to dominance. The disappearance of a significant heterozygosity fitness correlation when individuals older than juveniles are considered is consistent with the prediction that differences in survival among individuals are maximal early in life. The lack of a correlation between heterozygosity and access to dominance may be a consequence of few homozygous individuals attaining the age at which they might reach dominance. Two hypotheses have been proposed to explain heterozygosity-fitness correlations: genome-wide effects reflected by all markers or local effects of specific markers linked to genes that determine fitness. In accordance with genome-wide effects of heterozygosity, we found significant correlations between heterozygosities calculated across single locus or across two sets of eight loci. Thus, the genome-wide heterozygosity effect seems to explain the observed heterozygosity-fitness correlation in the alpine marmot.

“…Alpine marmots have undergone a severe bottleneck at the end of the last glaciation period, which is hypothesized to be the cause of the low genetic diversity found in extant populations of alpine marmots (Preleuthner & Pinsker 1993; Kruckenhauser et al . 1997).…”

“…Indeed, more than 48% of individuals from both sexes acquire dominance in their natal territory or in the immediate vicinity resulting in most of the available social males being genetically similar to females (see Appendix S3 for detailed information regarding dispersal patterns). As a result, the Alpine marmot is characterized by a low neutral genetic variability as estimated with allozymes (Preleuthner and Pinsker 1993), minisatellites (Rassmann et al 1994;Kruckenhauser et al 1997), and microsatellites (Cohas et al 2009; but see Goossens et al 2001) and by a low MHC variability (Kuduk et al 2012;Ferrandiz-Rovira et al 2015).…”

Sexual selection through female mate choice for genetic characteristics has been suggested to be an important evolutionary force maintaining genetic variation in animal populations. However, the genetic targets of female mate choice are not clearly identified and whether female mate choice is based on neutral genetic characteristics or on particular functional loci remains an open question. Here, we investigated the genetic targets of female mate choice in Alpine marmots (Marmota marmota), a socially monogamous mammal where extra‐pair paternity (EPP) occurs. We used 16 microsatellites to describe neutral genetic characteristics and two MHC loci belonging to MHC class I and II as functional genetic characteristics. Our results reveal that (1) neutral and MHC genetic characteristics convey different information in this species, (2) social pairs show a higher MHC class II dissimilarity than expected under random mate choice, and (3) the occurrence of EPP increases when social pairs present a high neutral genetic similarity or dissimilarity but also when they present low MHC class II dissimilarity. Thus, female mate choice is based on both neutral and MHC genetic characteristics, and the genetic characteristics targeted seem to be context dependent (i.e., the genes involved in social mate choice and genetic mate choice differ). We emphasize the need for empirical studies of mate choice in the wild using both neutral and MHC genetic characteristics because whether neutral and functional genetic characteristics convey similar information is not universal.

“…Rassmann et al (1994) analysed the Berchtesgaden population using multilocus DNA fingerprinting and confirmed the low degree of polymorphism already revealed in the previous allozyme study (Arnold 1990a). Kruckenhauser et al (1997) extended this investigation to six Austrian populations and two samples from Grisons (Switzerland). The results showed higher variability in the Swiss samples compared to five of the Austrian populations.…”

Microsatellite variation was studied in 11 populations of the Alpine marmot along a west-east transect through the present distribution range. The samples represent five autochthonous and six introduced populations. Eleven loci were analysed in nine populations and six loci in the two populations from France. In the populations from the Western Alps, there is no indication for reduced variability as has been assumed in previous studies. However, a decrease of variation in the autochthonous populations was observed from the west to the east. The introduced populations showed a heterogeneous pattern reflecting the geographic origin of the released individuals. The population from the Spanish Pyrenees harbours a high level of variation and is genetically closest to the French populations. In Austria, three of the introduced populations have low variation and are closely related to the autochthonous populations from the western part of Austria. In contrast, two introduced populations from the central part of Austria are highly variable and resemble the populations from France. At least for one of these populations an early introduction of founder individuals from the Western Alps has been documented.
