Isolation and structural identification of an alarm pheromone from the giant danio Danio malabaricus (Cyprinidae, Ostariophysi, Pisces)
… der synthetischen Komponente. Das natürliche Alarmpheromon wurde als 7-Hydroxybiopterin identifiziert. Bei Biotests mit 5 mL einer 0,4 myM 7-Hydroxybiopterin-Lösung in 20 L Aquarien konnte eine Schreckreaktion ausgelöst werden. Um die Spezifität und Selektivität des Pheromons zu verifizieren, …

The Role of Alarm Pheromones in Predation Avoidance By Adult Central Newts, Notophthalmus Viridescens
Alarm pheromones play an important role in predator/prey interactions. A chemical alarm system has been recently described for Notophthalmus viridescens. This alarm signalling system was tested in the field to determine if newts avoid areas marked with conspecific skin extract in a natural …

Mapping the Brain of the Clonal Raider Ant: Integrating Behavior, Neuroanatomy and Connectomics
… social behaviors, with ants using a variety of pheromones produced by different exocrine glands to communicate. For example, ants release alarm pheromones in response to danger to alert their nestmates and to trigger behavioral alarm responses. Despite extensive behavioral studies, the …

Comparison of orthologs across multiple species by various strategies
… that for one particular stimulus, response to alarm pheromone, the set of honey bee genes differentially expressed in the brain contains disproportionately large numbers of genes also found in mammals, including humans. Functionally, a large number of the human counterparts of these genes are …

Experience With Chemical Cues Influences Subsequent Behavior of Rainbow Darters, Etheostoma Caeruleum
… darters to red predator models and to either an alarm chemical (unconditioned fright stimulus) or blank water (control), and then subsequently tested the responses of the darters (number of hops) to the models (either red or blue) alone. The results of the study are ambiguous with respect to …

Communication in the hymenoptera : chemistry, ecology and evolution
… that are designed to attract females. The sex pheromone of male European beewolves Philanthus triangulum (Hymenoptera, Crabronidae) might have evolved according to the sensory exploitation hypothesis. A three-step scenario is supported by our studies. First, a major component of the honeybee …

Evolution of the pheromone communication system in the European Beewolf Philanthus triangulum F. (Hymenoptera: Crabronidae)
… This thesis examines the evolution of the pheromone communication in the European Beewolf Philanthus triangulum. Beewolf females are specialized hunters of honeybees and provision their progeny with paralyzed prey. Male beewolves establish and scent mark territories with a pheromone from a …

Behavioral and Physiological Evidence for Musk Gland Secretions as a Chemical Alarm Cue in the Cottonmouth, Agkistrodon Piscivorus
… they have also been suggested to function as alarm pheromones. I conducted two experiments to test the hypothesis that musk gland secretions function as an alarm signal in the cottonmouth (Agkistrodon piscivorus), using behavioral and physiological response variables. In a repeated-measures …
