anthropomorphism Endowing animals with human characteristics Associative learning (conditioning) the ability to form associations between previously meaningless stimuli and reinforcements such as rewards or punishments. Behavior A consequence of interactions of an animal and it's 1.environment, 2.mediated by sense organs and 3.effector organs, and dependent on the 4.physiological state of the organism. Behavior Response resulting from interactions of an animal and its environment. Insects may lack info available to people Behavioral Development Bias Internal State/processing structures differ Emotions are ill defined for humans (anger,hunger,sad) Effect on reproductive success Behavioral Development Function sexual selection adaptations to situations and environments selection pressures Behavior Development Cause External Stimuli Internal State Internal/External Interactions Classification in the Animal kingdom Phylum-Arthropoda, Chordata Class-Hexapoda (Insecta), Mammalia Effector organs Includes muscles, endocrine and exocrine glands Environment Includes external cues and stimuli and internal cues (physiological state) Ethology The study of behavior FAPs Fixed Action Patterns-species specified motor patterns. Once initiated, they require few or no external stimuli or additional sensory curs for their maintenance or completion Use flash signals tolure in males of other species by imitating their femme fatales Proturis sp. females' flash pattern.They eat the males and then switch patterns totheir own species tolure in a mate. Function of eye spots Frighten bird predators. Bird fear owls- moth exploits this Habituation the gradual lessening of responsiveness to a stimulus as experience finds it is to be harmless or at least unavoidable. proximate cause.deals with structural, physiological, genetic, How question developmental mechanisms.Ask how an individual manages to carryout an activity and they ask how mechanisms within an insect operate tomake the behavior possible. Insects can detect signals we cannot UV light, bat sonar, sounds, chemicals/pheromones, magnetic fields Behavior is performed appropriately the very first time. No experience is Instict/Innate Behaviors reqired. Prevalent in insects because- 1.short lifecycle 2.limits of small body size 3.complete metamorphosis sometimes termed "exploritory learning". Bees and Latent Learning wasps learn the location of their nests through landmarks recognized and remembered from previous orientation flights. Occurs without reinforcement. Learning modification of a behavior by experience that is enduring or relatively permanent and occurs as a result of experience or practice Lignum vitae trees on the island stopped blooming and died due to lack of sunlight because Lignum Vitae Key hurricanes hadn't happened to knock down other trees in the way. They could not scales which would die with the branches because they were non-mobile as adults. Antsvitae would protect the scales and in return could tap on the scale and receive dew. Wasps would imitate the ant and deposit eggs in the opened scale. The dying scales affected both the ants and wasps. the capacity to store information-is a prerequisite resulting in a linkage Memory between stimulus and response that would not have occurred without the previous experience with the stimulus Physiological State Includes such things as the hormonal status (not), age (life stage), gender, and if it has fed (or not) Sense organs Includes such things as eyes, antennae, proprioreception(touch), humitity, Johnston's organ(sound) A group of closely related "biological" species that happen tolack Sibling Species Complex readily distinguishing morphological features.They are, however, reproductively isolated, with the isolating mechanism typically being some form of subtle communication cue.Ex.fireflies, crickets, and leaf-roller moths Form of anthropomorphism, endows animals with teleology purposive(goal directed) behavior. Requires knowledge of goal, and capasity to use knowledge to direct behavior Why Question ultimate cause. ask why the animal evolved the proximate mechanism to do certain things. what we see today is the result of ultimate cause
