Initial orientation of crested newts Triturus cristatus and smooth newts Lissotriton vulgaris was measured following passive displacement to arenas placed at 12 test sites 0.213–24.2 km distant from the breeding pond. Newts were transported by car without visual and olfactory outward journey information, but had full access to local orientation clues at the release site during the night and early morning before testing. Within the area of previous migratory experience, the initial directional… 
Acoustic orientation in the great crested newt (Triturus cristatus)
Different degrees of heterospecific call attraction across life stages are suggested, and evidence that unnatural sound might have an adverse effect on breeding migrations is provided.
Map-like navigation from distances exceeding routine movements in the three-striped poison frog (Ameerega trivittata)
Three-striped poison frogs (Ameerega trivittata) can navigate home via a direct path from areas exceeding the range of their routine movements, suggesting a flexible map-like navigation mechanism.
Marsh frogs, Pelophylax ridibundus, determine migratory direction by magnetic field
Adult ranid frogs can obtain directional information from the Earth’s magnetic field as was shown earlier in urodeles and anuran larvae.
Orientation and navigation in Bufo bufo: a quest for repeatability of arena experiments
To resolve this question, tracking of freely moving toads should have greater potential than the use of arena experiments, and the potential influence of environmental factors on toad orientations is analysed using a MANOVA approach.
Arachnid navigation – a review of classic and emerging models
This work focuses on the most heavily studied spider models, highlighting the methodology used to deduce various aspects of the path integration machinery, and highlights some work being done on longer range spider navigators, and emerging work with other arachnid groups.
The significance of spatial memory for water finding in a tadpole-transporting frog
Twenty years’ monitoring of a population of Italian crested newts Triturus carnifex: strong site fidelity and shifting population structure in response to restoration
In 20 years of continuous monitoring, the population of Italian crested newt increased and was shown to be sex-dependent, with slightly higher values for males with respect to females, and a complete recapture rate.
Context-dependent dispersal, public information, and heterospecific attraction in newts
The results revealed that the great crested newt’s dispersal is context dependent and is affected by variation in heterospecific density, which suggests that individuals adjust their dispersal decisions at least partly based on public information provided by heterOSpecifics.
Sex differences in exploratory behaviour of the common toad, Bufo bufo
Evidence of sex differences in exploratory behaviour of amphibians obtained under controlled laboratory conditions is obtained, with males demonstrating more intensive and more goal-oriented exploratories behaviour than females.
Movement patterns of an arboreal gecko in fragmented agricultural landscapes reveal matrix avoidance
Animal movement through agricultural landscapes is critical for population persistence of species within fragmented native vegetation patches. However, perceived habitat quality and the structural


Initial orientation of newts (Triturus vulgaris, T. cristatus) following short– and long–distance displacements
Within the area of migratory experience, the initial directional choice of both species was significantly directed to home, which contradicts results obtained by other authors with a similar experimental design and using five distinct newt species.
Initial homeward orientation after long-distance displacements in the newt taricha rivularis.
It is suggested that animals homing from remote locations depend on random search to bring them close to the home territory, after which they sense its direction and move directly toward it.
Celestial orientation in the marbled newt (Triturus marmoratus)
These investigations have demonstrated that the marbled newt is able to orient using celestial cues, and the ambient geomagnetic field does not seem to be relevant to orientation of marbling newts since they were unable to orient themselves using the ambient Geomagnetic Field in the absence of celestial cues.
Homing ability and sensitivity to the geomagnetic field in the alpine newt, Triturus alpestris
Alpine newts tested in a circular arena chose a compass course in the direction of their breeding pond only when the ambient geomagnetic field and the celestial cues were simultaneously available, and failed to orient only when celestial cues or the geoagnetic field were the sole orientation cues available.
Orientation behaviour of toads (Bufo bufo) displaced from the breeding site

The results indicate that after displacement the initial orientation of B. bufo is based mainly on olfactory and magnetic cues, with visual control of straightness, which is similar to that of other toads.
Homing trajectories and initial orientation in a Neotropical territorial frog, Allobates femoralis (Dendrobatidae)
The results describe a very accurate homing behavior in male A. femoralis, and the straightness of trajectories and initial homeward orientation suggest integration of learned landmarks providing a map position for translocated individuals.
Magnetic orientation of the Common Toad: establishing an arena approach for adult anurans
This is the first study testing orientation of adult anurans with a controlled magnetic field of a known strength and alignment and it is speculated that toads had not enough time to relocate their position on an internal map, hence, they followed their former migration direction.
Magnetic compass mediates nocturnal homing by the alpine newt, Triturus alpestris
Findings indicate that newts are able to orient in the homeward direction at night using the magnetic compass as the sole source of directional information.
Sensory orientation in Notophthalmus v. viridescens (Amphibia: Salamandridae)
Adult red-spotted newts, Notophthalmus v. viridescens, were collected from an aquatic habitat and released on land in an arena 20 m from the shore of their home pond and olfaction is implicated as the sensory mechanism most essential to home pond orientation.
