- Explain survivorship and reproductive behaviorThe following equation is used to calculate the population growth rate, Ro, per generation from a life table. Iy is survival probability from birth to age x and my is fecundity at age x. Ro = Elkm Multiplying ly and my and summing it over all age categories in the life table gives the population growth rate per generation because: Calculating the reproductive output for each age class requires considering the survival probability to that age (a dead individual does not reproduce) and the fecundity at that age by multiplying them with each other. Summing over reproductive output for all age classes gives the total per capita growth rate of the population The fecundity at each age is lower when the survival is higher because of energy constraints. Multiplying probability of survival and fecundity in each age class takes this trade-off into account. Summing over reproductive output for all age classes gives the total per capita growth rate of the population The resulting type of growth…What defines the carrying capacity of a population? Choose All That Apply the maximum number of individuals a particular habitat can support an indicator of the functional requirements that individuals in a population need for growth and reproduction a reflection of the environmental resources that are needed to support a population
- Define the term ‘biological success’. Using labelled diagrams where appropriate, explain clearly why insects can be considered to be a biologically successful group. (400- maximum word limit)According to Grimes model, which characteristics (life history traits) apply to individuals in the "Competitive" strategy? Question 10 options: The offspring have a high survival rate All of these They produce relatively few offspring They are very mobile They invest very little in their offspring They have an older age of maturityConsider the temperature effect in the sex determination of a turtle species represented in the graph below. 100 What effect would a decrease in temperature below the epivotal temperature have on sex ratios of these turtles? 50 FT MT Temperature Fewer males and females will result. None of the other answers is correct. No difference in the proportion of females to males will result as only colder temperatures will alter the sex ratio in the offspring. More males than females will result. More females than males will result. To Percent female O O O O
