When a derived character state reverses back to something resembling the primitive condition

49
Q

Convergence

A

When a derived state arises more than once independently

50
Q

Homologous characters

A

Similar traits whose similarity is due to evolving from a common ancestral trait

51
Q

A

Similar traits whose similarity is due to convergent evolution. In other words, the characteristic evolved independently

52
Q

Independent evolution of similar traits

53

55
Q

Dispersal

A

Movement of an animal from its birthplace to where it reproduces

  • Significance: Promotes outbreeding; Leads to extension of a range or the reinvasion of a former range; Reduces intraspecific comptition
  • Density-Dependent or Innate
56
Q

Invasion

A

A type of dispersal that involves movement into a region not previously occupied by the species

57
Q

Atlantic Green Turtle Migration

A

Nesting populations of Ascension Island (East of Brazil) (< 20km in diameter)
After depositing eggs, females return to warm shallow waters off the Coast of Brazil. They will feed for several years and then return to the beach to lay another clutch of eggs.
The navigation mechanism is unknown and may involve a variety of mechanisms including an ability to detect the magnetic field of the Earth, to perceive polarized light, to use the sun and stars for orientation, and to hear low frequency sounds.

58
Q

Four types of migrations

A

Short Distance Migration: Ambystomatid salamanders from hibernacula to breeding pond
Altitudinal Migrations: Elk in western mountains spend the winters high on the mountains, but migrate to the valleys during the winter
Long-Distance Migrations: Birds, most breed in the more northern latitudes. (ex. Arctic Tern)

59
Q

Reasons for Migration

A
  • Lack of food in winter
  • Avoid energetic costs of a cold winter
  • Breed in high latitudes to take advantage of the long days that can provide more time to forage
  • Competition
60
Q

Circadian (diurnal) clock

A

An innate daily clock

61
Q

Circannual clock

A

Measures innate annual rhythms

62
Q

Map Sense

A

ability in many migratory animals to know precisely where they are even when in an area for the first time

63
Q

Homing

A

An innate ability to return to a home after foraging, migrating, or some form of displacement

64
Q

Life History Traits

A

All traits that affect an organism’s survival and reproducation

65
Q

Density-Dependent Factors of Population Size

A

Competition, Territoriality, Disease, Predation, Build-up of waste, Intrinsic factors

66
Q

Home Range

A

An area where an animal spends most of its time in its normal activities of gathering food, mating, and caring for young

  • -May overlap within a species
  • -Usually marked by pheromones, urine, or excrement
67
Q

Territory

A

The portion of a home range that is defended, usually from other members of the species

68
Q

“Dear Enemy” Recognition

A

The ability to recognize territorial neighbors has been called “dear enemy” recognition and may be advantageous since it minimizes time and energy spent on territorial defense and on the risk of injury

69
Q

Density-independent Factors of Population Size

A

Factors that limit population size regardless of density of population
-Associated with natural disasters or climate

70

  • Develops as an outgrowth of the body wall
  • Completely envelops the other membranes
82
Q

Yolk Sac

A

Contains the yolk, which composed of nutrients for the embryo. Other nutrients are stored in the albumen. By the end of development, the yolk sac is absorbed.
-Note that this is not a new development since fishes also have a yolk sac
