Semelparity
You reproduce once and then die
Iteroparity
You have multiple reproductive events across life
Microbial loop summarization
Recycles dead organic mater through bacteria and micrograzers. Crucial in open ocean
Succession
Gradual change in species composition over time in a habitat
PAHs
Toxic oil compounds harming larval fish development
K selected strategy
Cold deep sea temps slow development. High parental investment leads to fewer, more developed offspring
Example of ontogenetic shift using lionfish
Protogynous hermaphroditism
Female first turn male
Protoandous hermaphroditsm
Develop into males first then turn female
Parrot fish are an example of what?
Born female and turn male, protogynous hermaphrodites
Driven by the advantage of the larger male in reproductive success, such as defending territories and mating with multiple females
Sequential hermaphroditism vs simultaneous hermaphroditism
Sequential hermaphrodistism - when an organism changes sex during its lifetime
Simultaneous hermaphroditism - has both male and female reproductive organs
