Animal Behavior 5
Animal Behavior Quiz 5 USD Fall 2018 Dr. Andrea Liebl
| Question | Answer |
|---|---|
| What is an illegitimate receiver? | receiver who uses signal although not intended |
| What is an illegitimate signaler? | individual that adopts the behavior/signal of other species for its own gain |
| What is illegitimate receiver persistence? | there is a trade off because if you don't make the signal you don't get eaten, but you also don't get fed or a mate but if you do make the signal you probably get fed or mate or eaten but your fitness increases |
| What are some examples of illegitimate signalers? | orchid flowers, braxin wing, displays, mimics, camo/crypsis |
| What are the three main reasons for illegitimate signaler persistance? | 1. trade off 2. not enough evolutionary time 3. illegitimate signalers can learn |
| What is an honest signal? | signals that accurately represent quality of individual |
| What is an example of an honest signal? | anoles color/size of dewlaps and push-up abilities, birds sound, dancing in birds, morphological signals |
| Why honest signals? | They give an acurate assessment for mate selection, trade-offs from resources, often reflect development and leads to handicap hypothesis |
| What is the handicap hypothesis? | honest signal can be a handicap, but if you can maintain it then you're probably high quality |
| What is a cheater? | individual that uses dishonest signal to own fitness advantage |
| What is the benefit of being a cheater? | low risk with high reward |
| What is aggression? | attack or threat of attack on another individual |
| What are the proximate mechanisms of aggression? | testosterone, mate/ resources, social standing, presence of offspring, size, time of year |
| What are the ultimate mechanisms of aggression? | to gain/maintain reproduction, fitness, territory, life |
| What is the definition of competition? | interaction between individuals over a resource |
| Is competition always aggressive? | no |
| What is interspecific competition? | between multiple species |
| What is intraspecific competition? | within same species |
| What is animal personality/syndrome? | phenomenon where individuals vary systematicall in suites of behavior that are consistence within individuals thoroughout time, environment, and context |
| What is the proximate mechanisms of personality? | increase in any hormone, suit behaviors tend to work in tandom |
| What are the ultimate mechanisms of personality? | increases variation in a population, buffer from change |
| What are the consequences of personality? | speciation, need for cooperation, stuck with certain behavior (suits in tandem) |
| What is sexual selection? | Selection for a trait that gives san individual an advantage in acquiring mates |
| Why does sexual selection work? | allows females to be choosy |
| What is the sexual difference theory? | Male want as many mates as possible, and females want 1 or 2 of the best mates |
| What is the good parent theory? | male ornament/coloration/dispalays are sexually selected indicators of their capcity to provide parental care |
| What is the healthy mates theory? | male appearance is indicactive of gene quality |
| What is the runaway selection theory? | male trait and female preference are geneticallly linked and can be passed on and eventually leads to the trait being exaggerated and detrimental to health |
| What is chase-away selection theory? | trait isn't necessarily an honest trait, however male mutation for a novel display affects female mate choice and drives selection towards the exaggeration of the novel trait |
