Fig. 5 in Patterns of tooth crown wear in Dryomys nitedula (Mammalia, Rodentia): age-related variation in the light of annual cycle specifics based on museum collections
Fig. 5. Changes in the external appearance of the forest dormouse during the first year of life. The animal was caught in early June 2009 near Luhansk: a — 19 of June, 1–2 weeks old, feeding exclusively with insects, mainly locusts; b — 16 of July, 1+ month of age, active motions, feeding with insects, including locusts, butterflies, and mealworms; c — 18 of August, 2+ months of age, low mobility, willingly feeding with mealworms, also began to consume nuts, honey, and cookies; d — 16 of September, 3+ months of age, low mobility, feeding almost exclusively with nuts, honey and other energy-rich products instead of insects, which became less preferred.
Fig. 4 in Age determination of the Mongolian wild ass (Equus hemionus Pallas, 1775) by the dentition patterns and annual lines in the tooth cementum
Fig. 4. The times of eruption, development of cementum and formation of the annual lines in the first upper incisor (I1) at the labial (left) and lingual side (right).
Data from: Evaluating tooth strontium and barium as indicators of weaning age in Pacific walruses
<p>A dataset of calcium-normalized <sup>88</sup>Sr and <sup>137</sup>Ba concentrations from laser ablation transects across the cementum layer of 107 (female: n = 84, male: n = 23) Pacific walrus (Odobenus rosmarus divergens) teeth. Dataset includes spreadsheets containing elapsed time of laser ablation transect in seconds (ElapsedTime_s; laser transect speed = 5μm/s), calcium-normalized strontium concentrations (Sr_ppm_m88; values below limit of detection replaced with 1/2*limit of detection, see methods), and calcium-normalized barium concentrations (Ba_ppm_m137; values below limit of detection replaced with 0.5*limit of detection). Photos (in .tif format) of tooth cementum used to estimate the positions of cementum growth layer groups are included for each animal. For teeth where more than one laser ablation scar is visible in the photo, an arrow is included to indicate the laser ablation scar that corresponds with the included trace element data. Finally, a Word document containing metadata (Catalog Number/ID, Sex, Median Age Est., Coll. Year, Est. Birth Year), weaning age estimates produced by both a visual and mathematical method (Sr Vis. Est., Sr Math. Est., Ba Vis. Est., Ba Math. Est.), and a descriptive grouping of the patterns of accumulation of Sr and Ba (Sr Pat., Ba Pat.) are included. See methods and accompanying paper in Methods in Ecology and Evolution for more details.</p>
