Roitberg_et_al_repro_data

Data for female reproductive output and maternal body size:

Abbreviations of characters/columns (if not clear from their designations):

No, this column is for technical purposes of the author;

No_inv, inventary number (in the museum or in the working protocols of the 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;

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 (study subject) number in the author's extended database.

ln_rcm, natural logarithm of rcm.

Abbreviations of museums:
mkhar, Museum of Nature, Kharkiv National Karazin University;
mkiev, National Museum of Natural History Kyiv;
mtd, Senckenberg Natural History Collections Dresden;
zfmk, Zoological Research Museum A. Koenig Bonn;
zmb, Humboldt Natural History Museum Berlin;
zmh, Zoological Museum Hamburg;
zsm, Zoological State Collections Munich.

Comment 1. The codes “mkhar” and “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 traits.
