Mimicry

(continued from box above) Mimicry is when one species has evolved to resemble another organism. Müllerian mimicry is when two or more distasteful species may benefit from a shared warning coloration pattern, such as the monarch and viceroy butterflies who both share the orange and black patterns. Batesian mimicry is when harmless organisms can gain a selective advantage by resembling poisonous species, such as coral snake and a scarlet king snake. Many prey can also deter predators by startle coloration

Batesian mimicry is a form of mimicry where a relatively innocuous organism mimics another organism: one that its own predators avoid because it is poisonous or otherwise unpalatable (Ruxton 2004). There is selection pressure on the harmless organism to become a closer and closer replica of its venomous model and yet, in nature, no model is quite perfect (in fact, some are poor approximations, such as the scarlet kingsnake’s cobbled-together costume of the vastly more venomous coral snake). Yet we

Batesian mimicry occurs when an edible and harmless organism (the mimic) mimics a noxious and inedible organism (the model) in appearance (Ruxton et al 2004). Mimicry of the model by the mimic can lend it protection from predation (Ruxton et al 2004). An interesting type of Batesian mimicry seen in numerous butterfly species is female-limited polymorphic mimicry (Kunte 2009). Many species of swallowtail butterflies in the genus Papilio exhibit Batesian mimicry and Female-limited polymorphism (Kunte

Mimicry of other toxic species Thaumoctopus mimicus is said to use imperfect mimicry, defined as the using poor to decent imitations of multiple morphs, rather than strong resemblance to one species (Hanlon et al., 2008; Huffard et al., 2010). As mentioned in the previous section, they replicate the coloration of multiple forms of flatfish, but more dramatic morphs are displayed while individuals are swimming in the mid-water range of the water column or while interacting directly with aggressive

the forces that initiate the evolutionary pattern of color polymorphism and mimetic coloration using coral snake mimicry as a useful model to study convergent evolution. Coral snake mimicry can be used to show how selection and other evolutionary processes drive powerful phenotypes among populations. Cox’s research revolves around the opposition of previous objections to coral snake mimicry to show that several harmless, nonvenomous snakes are mimics of highly venomous snakes. This led to the arise

News Analysis Assignment #1: Aggressive Mimicry in Assassin Bugs The news article I have chosen is titled “Assassin bug lures spiders by mimicking prey”1. In this article, author Mark Kniver states that researchers observed assassin bugs (Stenolemus bituberus) preying on spiders by mimicking prey trapped in a web through a behavior called “aggressive mimicry”1. Stenolemus bituberus will first disturb one of the strands of a spider’s web, tricking the spider into thinking that it has caught a

An independent variable, which is what is varied during the experiment, is what will affect the dependent variable. A change in the independent variable directly causes a change in the dependent variable, and you can only have one independent variable. The independent variable is the behavior of one participant that triggers the behavior of another participant. In the first study, the alcoholic beverage and conversation topic selected by Participant #1 is the independent variable. In the second study

called ‘Zelig’ where the actor named Woody Allen imitated other people’s words and actions. Chartrand & Bargh did three experiments total: first was ‘the test of unintentional mimicry between strangers’, second was ‘the adaptive function of the chameleon effect’, and third was ‘the individual differences in non-conscious mimicry’. In all three experiments they used students from the introductory psychology course at New York University as participants. The experiments were all videotaped with the participant’s

Influences on Children’s Prosocial Behavior Prosocial behavior is important to psychologists because it is a significant part of development in a child. Children learn prosocial behavior from many influences in their lives including parents, peers, teachers, caregivers, and the media (Williams, O’Driscoll, & Moore, 2014). Prosocial behavior is any action intended to help others. Children learn their earliest behaviors from their parents. If a child never participated in prosocial behavior, there
