摘要

利用三维几何形态计量学方法，我们揭示了两栖河马在本体发育过程中的主要变化。幼年河马颅骨元素形状变异的主要变化可能与哺乳中断有关。颅骨变异性的较小变化可能与性成熟有关。半地标和地标是区分现生物种的有力工具，因此，这种技术在未来研究化石物种时也将特别有用。

Talking heads: disentangling the shape changes of the large extant hippopotamus during its ontogenetic development.

Using a 3D geometric morphometrics approach, we shed light on the major changes during the ontogenetic development of Hippopotamus amphibius. The main shift in the shape variability of cranial elements in juveniles can probably be related to the interruption of suckling. A less stressed shift in the cranial variability can probably be related to the attainment of sexual maturity. Semilandmarks and landmarks are powerful tools to discriminate between extant species and, therefore, this technique will be particularly useful in the future to study fossil ones as well.

期刊介绍： The official journal of the International Society of Zoological Sciences focuses on zoology as an integrative discipline encompassing all aspects of animal life. It presents a broader perspective of many levels of zoological inquiry, both spatial and temporal, and encourages cooperation between zoology and other disciplines including, but not limited to, physics, computer science, social science, ethics, teaching, paleontology, molecular biology, physiology, behavior, ecology and the built environment. It also looks at the animal-human interaction through exploring animal-plant interactions, microbe/pathogen effects and global changes on the environment and human society. Integrative topics of greatest interest to INZ include: (1) Animals & climate change (2) Animals & pollution (3) Animals & infectious diseases (4) Animals & biological invasions (5) Animal-plant interactions (6) Zoogeography & paleontology (7) Neurons, genes & behavior (8) Molecular ecology & evolution (9) Physiological adaptations
