The fecundity-advantage-hypothesis (FAH) explains larger female size
relative to male size as a correlated response to fecundity selection. We
explored FAH by investigating geographic variation in female reproductive
output and its relation to sexual size dimorphism (SSD) in Lacerta agilis,
an oviparous lizard occupying a major part of temperate Eurasia. We
analysed how sex-specific body size and SSD are associated with two
putative indicators of fecundity selection intensity (clutch size and the
slope of the clutch size-female size relationship), and with two climatic
variables throughout the species range and across two widespread
evolutionary lineages. Variation within the lineages provides no support
for FAH. In contrast, the divergence between the lineages is in line with
FAH: the lineage with consistently female-biased SSD (L. a. agilis)
exhibits higher clutch size and steeper fecundity slope than the lineage
with an inconsistent and variable SSD (L. a. exigua). L. a. agilis shows
lower offspring size (egg mass, hatchling mass) and higher clutch mass
relative to female mass than L. a. exigua, i.e. both possible ways to
enhance offspring number are exerted. As the SSD difference is due to male
size (smaller males in L. a. agilis), fecundity selection favouring larger
females, together with viability selection for smaller size in both sexes,
would explain the female-biased SSD and reproductive characteristics of L.
a. agilis. The pattern of intraspecific life-history divergence in
L.agilis is strikingly similar to that between oviparous and viviparous
populations of a related species Zootoca vivipara. Evolutionary
implications of this parallelism are discussed.

Abbreviations of characters/columns (if not clear from their

primary researcher); ssp, subspecies/clade: 1 L. a. agilis, 3 L. a.
exigua; reg3, code of the study sample as in Roitberg et al., 2015, Table
1; sta, "stages": ad adult, gr gravid, m junger adult, sub
subadult, j (=juv) juvenile; NB: subadults and juveniles, as well as
unsexed individuals, were excluded from all analyses in Roitberg et al.
2015; sex: 1 males, 2 females, 3 unsexed; Num , individual (study subject)
number in the author's extended data base. filter_adults: 1

represent established abbreviations of the corresponding museums and used
for simplicity. Comment 2. This data table does not include Sample 3
(South Sweden) and Sample 9 (Russia, Ciscaucasia 1) because for these
samples we used published mean values (respectively, Olsson, 1988 and
Ushkalova, 1976). Comment 3. SVL-values for Sample 4 (Poland) were
obtained by extracting log(SVL)-values from published scatterplots
(Borczyk & Paśko, 2011: Fig. 1, A,B) and subsequent re-calculating
the raw values using the exponent function. Comment 4. SVL-values for
Sample 10 (Russia, Ciscaucasia 2) and Sample 11 (Russia, Ryazan Region)
were obtained from published histograms (respectively, Lukina, 1966: Fig.
22 and Zharkova, 1973: Fig. 4). Comment 5. SVL-values for the other
samples are original data of the authors.Roitberg_et_al_repro_dataData for

sample as in Roitberg et al., 2015, Table 1; data: "real", usual
data, which relate to real individuals; "sur", surrogate data
which were generated for those samples where only mean values and standard
deviations were available; these artificial samples were used in
ANOVA/ANCOVA models (see Roitberg et al. 2015 for details and references);
svl, maternal snout-vent length; cs_t, egg stage: 1 'enlarged
follicles', 2 'oviductal eggs', 3 'corpora
lutea', 4 'laid eggs'; cs, clutch size; m2,
post-oviposition female mass; cm, clutch mass (the total mass of the
freshly deposited eggs); rcm, relative clutch mass (in %); egg_m, mean egg
mass per clutch; hm, mean hatchling mass per clutch ; Num, individual

natural logarithm of rcm. Abbreviations of museums: mkhar, Museum of

“mkiev” do not represent established abbreviations of the corresponding
museums and used for simplicity. Comment 2. Sample 3 (South Sweden) should
actually include some additional values which could not be extracted from
the scatterplot (Olsson, 1993: Fig. 1) because the corresponding points
were superimposed. The resulting bias is obviously minor, however: the
published values for mean maternal SVL, mean clutch size, and the maternal
SVL-clutch size correlation (Olsson, 1993; Olsson & Shine, 1997a)
are close to those of Sample 3. See Roitberg et al. (2015) for important
comments to our study

most study samples, values for longitude, latitude, and climatic variables
are average values for several sites from which the study animals were
collected; sites which provided relatively small amount of data were not
considered for computing these average values. Specifically, for Sample
16, most study animals come from surroundings of Nizhnyaya Neninka
(Soltonskiy district); for Sample 17, most study animals were collected
near Yailyu (Turochakskiy district). These localities were taken as
reference sites for the corresponding
samples.Roitberg_et_al_geographic_distancesGeographic distances among
study samples (in km) used in our Mantel tests: See Fig. 1 in Roitberg et
al. (2015) for geographic map and Table 1 for the phenotypic
characteristics of the study samples. The distances were calculated using
the geographic coordinates. Note that for most study samples, values for
the longitude and the latitude are average values for several sites from
which the study animals were collected; sites which provided relatively
small amount of data were not considered for computing these average
values.
