Knowledge of factors influencing the timing of reproduction is important for animal conservation and management. Brown bears (Ursus arctos) are able to vary the birth date of their cubs in response to their fat stores, but little information is avail

Feeding and locomotor activity of one male and three female koalas have been continuously observed for one year at Taronga Zoo, Sydney, Australia. Activity was not restricted to the night, but showed a clear day–night distinction with activity maxi

Shrub encroachment as a result of heavy grazing is assumed to affect species diversity negatively. However, shrubs may be important for animals because they provide shelter and nesting sites. In this study we analyzed the importance of shrubs as habi

With the use of different light and electron microscopic methods, we investigated the subcellular organization of afferent trigeminal terminals in the upper beak of the homing pigeon, Columba livia, which are about 5 m in diameter and contain superpa

In various insect and arachnid species, three different types of photoreceptors that do not serve image processing have been discovered and analyzed by means of neurobiological methods: They can be found for example: (1) as lamina and lobula organs (

We present a new model of magnetic-field reception in magnetite-containing nerve terminals, which have recently been identified in the upper-beak skin of homing pigeons. The potentially magnetoreceptive nerve cells comprise chain-like aggregates with

Scorpions are nocturnal animals whose circadian activity rhythm is entrained via light/dark programs to the median and lateral eyes. Timing of light signals conveyed by the median eyes is modified by feedback from the circadian pacemaker. Using a sim

Central nervous system ganglia within the head of the beetle Pachymorpha sexguttata were labeled using an antibody that recognizes an evolutionarily conserved region of the period (per) gene product of Drosophila melanogaster. per and the protein it

The identification of ferrimagnetic iron minerals in the skin of the upper beak of homing pigeons poses fundamental questions on the principles at work in magnetoreception. Aspects concerning the type of mineral, the size, shape and arrangement of th
