Reproductive Adaptations Flashcards
Marine Ecology and Populations
1
Q
Sperm Storage
A
- Organism isn’t able to produce a viable offspring at the time of mating
- Organism can hold sperm until the time is right for fertilization to occur
2
Q
Parthenogenesis
A
- Cloning
- Female (rarely male) gamete cell develops without fertilization
3
Q
Why might an organism utilize parthenogenesis?
A
- They are incapable of sexual reproductive
- They can switch between sexual reproduction and parthenogenesis depending on environmental conditions (facultative)
4
Q
Direct Developing Larvae
A
- Larvae look like the adult
- Low dispersal potential
5
Q
Lecithotrophic Larvae
A
- Yolk sac = utilized for nutrition during dispersal
- Greater dispersal potential than direct developing larvae
6
Q
Planktotrophic Larvae
A
- Feed in the water column
- Can disperse over long distances
7
Q
Pelagic Larval Duration (PLD)
A
The period of development spent in the water column as plankton
8
Q
Dispersal Distance
A
How far larval fish travel while in plankton stage
