Animal Behavior Flashcards
The study of how animals move in their environment, how they interact socially, how they learn about their environment, and how an animal might achieve cognitive understanding of its environment
Animal behavior
Importance/significance of studying animal behavior
For early detection of sick animals
Importance/significance of studying animal behavior
A factor in obtaining maximum production and efficiency in breeding, feeding, and management
(Reflexes and responses) what the animal has at birth (example: nursing and searching for food)
Instinct
Learning to respond without thinking, response to certain stimulus is established as a result of habituation
Habituation
Learning to respond in a particular way to stimulus as a result of reinforcement when the proper response is made.
-reward and punishment
Conditioning
A reward for making the proper response
-reward
Reinforcement
The ability to respond correctly to a stimulus the first time that a new situation is presented
Reasoning
The ability to learn to adjust successfully to certain situations. Both short-term and long term memory are part of intelligence.
-present in higher animals like apes
Intelligence
Genes
Innate
Shaped by natural selection
-developed through experience
-survival of the fittest
Behavior
Many behaviors directly increase an organism’s fitness, that is, they help it survive and reproduce
Behavior
4 questions to understand a behavior
- Causation ( what causes the behavior?)
- Development (how does the behavior develop?)
- Function/ adaptive value (how does the behavior affect fitness)
- Phylogeny (how did the behavior evolve?)
For example sa zebra finches ang nagcocause ng behavior nilang magkanta ay ang appearance ng female tapos ang hormones nila
Causation
Nadevelop nila ang pag-sing from their dads and other finches from their surroundings
Development
Example nito is need nila na magcreate ng melodies para lalong dumami or magprocreate
Function / adaptive value
How nag-evolve ang behavior
Phylogeny
Cues that trigger behavior
- External, example neto is ang migration
- Internal, example neto is ang circadian rhythm
- Combination, example neto is ung mating behaviors
-A behavior in which animals move from one location to another in a seasonal pattern
-Environmental cues that trigger the autumn migration include air temperature, day length, and food availability
Migration
Example: may jetlag ka nung lumipat ng ibang place, kahit may sun if nasanay ang body clock mo na matulog within sa mga oras na yon matutulog ka
Circadian rhythm
Example: mating behaviors may be triggered in an animal only when it’s in the right hormonal state, an internal cue, and when it sees a member of the opposite sex, an external cue
Combination
Are genetically hardwired and are inherited by an organism from its parents
Innate behaviors
-Are not inherited, they develop during an organism’s lifetime as the result of experience and environmental influence
-acquired from experiences
Learned behaviors
-There are some examples of behaviors that are really and truly hardwired. These behaviors take place in a highly predictable way in response to the right stimulus, even if the organisms has never before encountered that stimulus
-Eating of placenta (survival instinct)
Mostly innate behaviors
An organism is genetically programmed to develop a behavior, but the form the behavior takes depends on the individual’s experience
Partly innate, partly learned behaviors
-In other cases, behaviors are largely dependent on experience-they’re learned-and can’t be fully explained by genetic programming
-example: sa cattle, may electric fence tas pag na-ground syempre mafifeel nila kaya iiwasan na nila na magtouch sa fence doon
Mostly-learned behaviors
Causes of Behavioral Responses in Animal
-Result of 3 interacting forces
1. Heredity (genetics)-breed
2. Learning Experiences
3. Intelligence
certain strains/breeds within a species have been selected on a genetic basis and then trained for a specific behavioral response
E.g:
horses-excellent for trotting, pacing, or draft
terriers-for fighting at the slightest provocation
beagles-for hunting and run in packs with little fighting
Internal factors
A. Can affect the growth and development of many parts
e.g: sensory/motor growth
B. Genes are responsible for production of various enzymes, hormones, and other chemical substances in the body
e.g: chicken undergoes sex reversal depending on the hormones in the blood stream
Produces behavioral response in several ways:
Types of learning behavior
A. Habituation
B. Imprinting
C. Classical conditioning
D. Operant conditioning
E. Insight learning (reasoning)
-Simplest type of learning
-means by which animal learns to ignore certain stimulus
-an animal gradually stops responding to a repeated stimulus
-form of non-associative learning meaning that the stimulus is not linked with reward and punishment
Habituation
a simple and highly specific type of learning that occurs at a particular age or life stage during the development of certain animals such as ducks and geese
-example neto is sa ducks where yung unang makita niyang gumalaw within hatching, siya na yung irerecognize niyang parent or un ang susundan niya
Imprinting
born in an immature and helpless condition, requiring care for some time after birth
Altricial
examples of altricial
parrots, pelicans, and songbirds
capable of movement and self-sufficiency soon after birth
Precocial
examples of precocial
chicken, duck, and rhea
-a response already associated with one stimulus is associated with a second stimulus to which it had no previous connection
-example is the pavlov’s dog experiment where ang 1st stimulus ay food at 2nd stimulus ay ang bell so in the experiment kinonnect ang pagdrool sa food and bell ng dog
Classical conditioning
-more on trial and error
-more on giving a reward or punishment
-a bit different than classical conditioning in that it does not rely on an existing stimulus-response pair. Instead, whenever an organism performs a behavios-or an intermediate step on the way to the complete behavior-it is given a reward or punishment
-example neto is yung mouse in a box with buttons na pag naclick ang tama is bibigay ng food tas pag nalampas sa grid na electric magground ang mouse
Operant conditioning
-most prevalent on higher animals
-ability to respond correctly the first time animal encounters a certain situation
-example neto is ang chimpanzee in a room na may banana and boxes tas nakuha nila ang banana with the help of stacking the boxes
Insight Learning (reasoning)
-ability of animals to learn to adjust successfully to certain situation
-sometimes defines as the organization of behavior(ability to learn from experience and to solve problem)
-varies greatly among individual within species as well as species
-mammals to be most intelligent of all animals
Intelligence
Primates-like apes, monkeys, and chimpanzees
Carnivores-predator
Ungulate(grazing animal)-prey
From most intelligent to least
-internal state of an animal which causes the immediate behavioral response
-drives or tendencies to respond in a particular manner
-e.g: hunger, thirst, elimination, sex, pain
Motivation
Hypothalamus and Endocrine Glands
Organs involved in Motivation
controls many types of behavior
-has inhibitory or stimulating center
Hypothalamus
-especially sexual activities(anterior pituitary gland)
-ovulation, onset of puberty, and normal cycle in female
Endocrine glands
-when one animal transmits information to another animal causing some kind of change in the animal that gets the information
-usually between animals of a single species, but it can also happen between2 animals of different species
-can help animals find mates, establish dominance, defend territory, coordinate group behavior, and care for young
Communication
Methods of animal communication
- auditory signals/sound
- pheromones/chemicals
- visual signs/displays
- tactile signals/touch
particularly important in birds, who use sounds to convey warnings, attract mates, defend territories, and coordinate group behaviors. Some birds also produce birdsong, vocalizations that are relatively long and tend to be similar among the members of a species
auditory signals/ sound
