Such breakthrough was made possible because the method relies on a consistent comparative reference system to compare shapes, the latter which is computed using the Cartesian coordinates of homologous landmarks. It has been shown elsewhere that traditional comparative reference systems based on anatomy, and oriented in stereotyped postures, such as the Frankfurt plane at rest, the Lateral Semicircular Canal when the animal is in alert, or the cranial floor when the animal is flying, are all inconsistent for anatomical comparisons. They vary too much and unpredictably across species. An extraordinary example of the problems that can arise in descriptive and comparative anatomy when using such reference systems is the traditional interpretation of the head of the Woodcock. Anywhere in literature it is written that the eyes of this gamebird are oriented backwards to protect itself from predators. Here, using geometric morphometrics it is demonstrated that the woodcock＇s skull is highly transformed, yet following a normal trend among birds. In turn, using GM it is demonstrated that the collective wisdom about this oddity is simply the result of interpreting the anatomy of its skull using unreliable reference systems.展开更多

Morphological examination also indicated these specimens were identical to B. candidus. We concluded that the Chinese white cross-band krait, previously identified as B. multicinctus in southwest and south China, should be recognized as B. candidus, a new record in China, and B. m. wanghaoti should be invalid.

文摘Eucotylidae is a family of microphalloid digeneans parasitising as adults in the urinary system of birds.There are few molecular data on members of this family,and phylogenetic relationships of its genera and species are still unclear.Here we present new morphological and molecular data on a eucotylid species Tanaisia atra(Nezlobinsky,1926).Specimens of T.atra were found in Eurasian Coot Fulica atra Linnaeus,1758 in European and Asian parts of Russia and examined using optical and SEM microscopy and molecular techniques.We report the presence of a well-developed cirrus sac and different types of tegumental scales in this species for the first time.All molecular markers used in our study(ITS2 region,28S rRNA and cox1gene)indicate that T.atra isolates from European and Asian parts of Russia are conspecific.In phylograms based on ITS2 region and 28S rRNA gene sequences,T.atra clustered with other Tanaisia spp.
