PROPAGULES AND OFFSPRING. Patterns of Development. Nutritional mode. 1) Planktotrophy. - larval stage feeds . This separates marine invertebrates from all others – can feed in dispersing medium. - Probably most primitive. Patterns of Development. Nutritional mode.
Parent and Offspring. Organisms. An organism is any living thing made up of cells. Butterflies Dogs Trees Humans Ants Lions. Parent Organism and Offspring. Parent Organism is the parent of the offspring (usually a mom and dad). Dog Cow Offspring are the children of an organism.
Dam/Offspring Interaction. Dam/Offspring Interaction. What type of relationship is it? Care giving and care seeking Giving on the part of the mother, known as “Maternal” Care seeking on the part of the young Begin shortly after birth & extend until the young are weaned.
CS206. Evolutionary Robotics. More fit organisms survive and reproduce. Less fit organisms die. Offspring with genetic variation. BIOLOGICAL EVOLUTION. CS206. Evolutionary Robotics. 0.3 0.4 … 0.7. More fit organisms survive and reproduce. Make modified copies
BIOL 3240 Plant and Animal Ecology – Life Histories. Offspring Number Versus Size. ___________________: If organisms use energy for one function such as growth, the amount of energy available for other functions is reduced. Leads to trade-offs between functions such as… .
Genetic Diversity of Offspring. Genes have a better chance of survival if they are rearranged at each generation Only offspring that are not diverse are twins Identical twins Fraternal twins. Why do you think it would be advantageous to have genes rearrange each generation?

How large should offspring be?. Trade-off between number and size of offspring. Produce many small OR few large? Can be dictated by environmental context; i.e., the reproductive strategy may include phenotypic plasticity e.g. Stator limbatus ( a seed beetle). Seed beetle: Stator limbatus.
