The translational control of many maternal mRNAs in oocytes and early embryos relies on changes in poly(A) tail length; the factors controlling poly(A) tail length are being identified in a range of species.

ancylostoma tubaeforme was originally described as a separate species parasitizing the cat. the adults of a. tubaeforme are 7 to 12 mm long. a. tubaeforme can be differentiated from the adults of a. braziliense and a. ceylanicum by the presence of three teeth. here we describe the first re­port of a. tubaeforme in a persian young female leopard, 2-3 years old, with head and trunk length 120 cen...

BACKGROUND There is increasing interest in recording tail damage in pigs at slaughter to identify problem farms for advisory purposes, but also for benchmarking within and between countries as part of systematic monitoring of animal welfare. However, it is difficult to draw conclusions when comparing prevalence's between studies and countries partly due to differences in management (e.g. differ...

A close relationship between morphology and habitat is well documented for anoline lizards. To test the generality of this relationship in lizards, snout-vent, tail, and limb lengths of 18 species of Tropidurus (Tropiduridae) were measured and comparisons made between body proportions and substrate usage. Phylogenetic analysis of covariance by computer simulation suggests that the three species...

introduction: sexual dimorphisms in biological structures such as brain and behaviour have been widely recognized in animals and humans. the purpose of this study was to examine whether there are sex differences in the size of the cerebellum with other body traits, such as the head, tail and brain. methods: twelve grasscutters comprising of 6 males and 6 females were used in this study. each br...
