Light at the end of the tunnel: Integrative taxonom y delimits cryptic species in the Tetramorium caespitum complex (Hymenoptera: Formicidae)
Species delimitation is fundamental for many biolog ical studies; its importance extends from regional faunistics over behavioral research to the reconstruction of evolut i nary history. However,Expand

Representation of Acoustic Communication Signals by Insect Auditory Receptor Neurons
Despite their simple auditory systems, some insect species recognize certain temporal aspects of acoustic stimuli with an acuity equal to that of vertebrates; however, the underlying neuralExpand

Auditory interneurones in the metathoracic ganglion of the grasshopper Chorthippus biguttulus. I, Morphological and physiological characterization
1.Auditory intemeurones originating in the metathoracic ganglion of females of the grasshopper Chorthippus biguttulus can be classified as local (SN), bisegmental (BSN), T-shaped (TN) and ascendingExpand

Single auditory neurons rapidly discriminate conspecific communication signals
Animals that rely on acoustic communication to find mates, such as grasshoppers, are astonishingly accurate in recognizing song patterns that are specific to their own species. This raises theExpand

Desert ants Cataglyphis fortis use self-induced optic flow to measure distances travelled
While foraging, desert ants of the genus Cataglyphis use a vector navigation (route integration) system for homing. Any vector navigation system requires that the animal is able to evaluate theExpand

Temperature dependence of temporal resolution in an insect nervous system
Abstract. The vast majority of animals are poikilotherms, and thus face the problem that the temperature of their nervous systems rather smoothly follows the temperature changes imposed by theirExpand

Perception of electric properties of objects in electrolocating weakly electric fish: two-dimensional similarity scaling reveals a City-Block metric
During electrolocation weakly electric fish monitor their self-emitted electric signals in order to detect and evaluate nearby objects. Individuals of the mormyrid species Gnathonemus petersii wereExpand

Lateral optic flow does not influence distance estimation in the desert ant Cataglyphis fortis.
The present account answers the question of whether desert ants (Cataglyphis fortis) gauge the distance they have travelled by using self-induced lateral optic-flow parameters, as has been describedExpand

Influence of amplitude modulated noise on the recognition of communication signals in the grasshopper Chorthippus biguttulus
The detection of acoustic communication signals in the presence of sinusoidally amplitude modulated noise was investigated in males of the grasshopper Chorthippus biguttulus. The auditory system ofExpand

Efficient transformation of an auditory population code in a small sensory system
Optimal coding principles are implemented in many large sensory systems. They include the systematic transformation of external stimuli into a sparse and decorrelated neuronal representation,Expand
