The identity of Rana margaritifera Laurenti, 1768 (Anura, Bufonidae).
Rana margaritifera was described by Laurenti in 1768 and currently is associated to the genus Rhinella, under the combination Rhinella margaritifera. Currently, the R. margaritifera species group consists of 16 recognized species. Furthermore, many additional species have been suggested to exist in this group which highlights the ambiguity surrounding the identity of Rhinella margaritifera and ...
متن کاملMasters of change: seasonal plasticity in the prey-capture behavior of the Alpine newt Ichthyosaura alpestris (Salamandridae).
Transitions between aquatic and terrestrial environments are significant steps in vertebrate evolution. These transitions require major changes in many biological functions, including food uptake and transport. The Alpine newt, Ichthyosaura alpestris, is known to show a 'multiphasic lifestyle' where the adult shifts from a terrestrial to an aquatic lifestyle and then back to a terrestrial lifes...
متن کاملPatterns of morphometric variation in the alpine newt (Mesotriton alpestris) at the southern limit of its distribution: environmental correlates.
We applied multivariate analyses to an array of body measures of alpine newt specimens derived from 11 local populations in Greece to describe, analyse and detect patterns and putative causes of within-population and among-population morphometric variation. The observed morphometric variation was partitioned into several independently varying aspects of the external phenotype, frequently follow...
متن کاملDissociation and Reaggregation of Embryonic cells of Triturus alpestris
C E L L movement and migration seem to play an important role in the formation of tissue-patterns during embryogenesis. Phenomena such as the appearance of loosely attached cells in the mesoderm, or of the freely migrating neural crest cells, are quite common in embryonic development. Since the tissues of adult organs are mostly rather compact in structure it seems that the capacity of isolated...
متن کاملThe Life of the Smooth Newt (Triturus vulgaris) after Metamorphosis
After metamorphosis. smooth or common newts (Tritltrus vulgtzris vltlgaris [Linn]) disperse on land. where they live a s juveniles before returning to the water as breeding adults. The population age-structure was obtained by dissecting the standard length frequency distribution. a procedure which is justified in the text. Juveniles have an uncomplicated age-structure, the nurnber of individual...
