    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Zoology; Urine communication; Behavior; Spatial scale; Male pheromone; Primer pheromone; Zoologi; Olfaction;

    Abstract : Locating and evaluating a suitable partner for mating is one of the most important events in any sexually reproducing organism. To achieve this, an animal must be able to locate its partner over both long and short distances, and finally evoke the proper mating behaviour. READ MORE

  4. 22. Learning and memory in moths - plasticity in behaviour and neurophysiology

    Author : Ruey-Jane Fan; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; proboscis extension reflex PER ; LTM; MTM; STM; memory; inter-trial-interval ITI ; inter-stimulus interval ISI ; US; CS; olfaction; Associative learning; classical conditioning; discrimination; the US pathway; Ecology; Ekologi; Animal physiology; Djurfysiologi;

    Abstract : The moth, Spodoptera littoralis, was demonstrated to be a new model system for studying mechanisms underlying odour conditioning. In the experiments a restrained moth was trained to learn an association between a conditioned stimulus (CS) and an unconditioned stimulus (US). READ MORE

  5. 23. Olfactory Function : The Influence of Demographic, Cognitive, and Genetic Factors

    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Olfaction; odor identification; odor threshold; odor discrimination; aging; gender; ApoE; BDNF; val66met; association study; population-based; Psychology; psykologi;

    Abstract : Olfactory function is affected by demographic, cognitive, and genetic factors. In the present thesis, three empirical studies investigated individual differences in olfactory ability. Study I explored demographic and cognitive correlates in common olfactory tasks; odor detection, odor discrimination, and odor identification. READ MORE

  6. 24. Pheromonal Mediated Behaviour and Endocrine Responses in Salmonids : The impact of Cypermethrin, Copper, and Glyphosate

    Author : Alia Jaensson; Ingvar Brandt; Håkan Olsen; Kjell Döving; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cypermethrin; copper; glyphosate; behaviour; hormones; pheromones; olfaction; 11-ketotestosterone 11-KT ; 17α; 20β-dihydroxy-4-pregnen-3-one 17; 20β-P ; reproduction; Toxicology; Toxikologi; Biologi med inriktning mot ekotoxikologi; Biology with specialization in Environmental Toxicology;

    Abstract : The effects of cypermethrin, copper and glyphosate on the endocrine system and subsequent response to female pheromones were investigated in mature male brown trout (Salmo trutta) parr.  Responses measured were the amount of strippable milt, blood plasma levels of both an androgen (11-ketotestosterone (11-KT)) and a progestin (17α,20β-dihydroxy-4-pregnen-3-one (17,20b-P)), and behavioural changes.
