Fig. 4 in Toward a better understanding of habituation process to human observer: A statistical approach in Macaca leonina (Primates: Cercopithecidea)
Fig. 4. Proportions of age-sex classes recorded during scan samples during partial, advanced, and full habituation stages. Chi-squared tests were performed for each habituation stage with the theoretical results based on troop demography (NM.= 14, NF. = 42, NSub-A. = 10, NJuv. = 77): adjusted residuals (dots) were significant when their absolute value exceeded 2.

Posterior probability distributions of movement, social, inactivity, and feeding behaviour observations for each habituation stage (i.e., partial, advanced, and full habituation) according to age-sex class (i.e., adult male, adult female, sub-adult, and juvenile), computed with the multinomial logit model.

Fig. 35. Tamiobatis vetustus NMNH 1717 in Braincase Of The Upper Devonian Shark Cladodoides Wildungensis (Chondrichthyes, Elasmobranchii With Observations On The Braincase In Early Chondrichthyans
Fig. 35. Tamiobatis vetustus NMNH 1717. Ventral view of braincase, depicting four alternative scenarios of basicranial arteries discussed in the text. Note disagreements over the foramen for the orbital artery/anterior palatine ramus, site of efferent pseudobranchial foramen, and the extent to which internal carotid and orbital arteries were enclosed by cartilage. The preferred arrangement is similar to that reconstructed in Cladodoides (fig. 21). No scale.
