Ecological adaptations

An ecological adaptation is any morphological, physiological, or behavioral trait of an organism that allows it to survive and reproduce in a habitat or ecosystem. Adaptation is a biological mechanism by which an organism gradually gets more acclimated to its surroundings.

6a. Fill in the table below with the expected characteristics of r vs K selected species. r-selected species K-selected species Timing of maturation Longevity Parental care Number of offspring Size of offspring 6b. Based on your table, would a species that provides long-term parental care and has few offspring be considered an r-selected or K-selected species? What is an example of such a species? 6c. Why is long-term parental care associated with having few offspring during a reproductive episode?

4. A biologist is using a simulation to model populations of African hornbills (Bycanistes spp. and Ceratogymna spp.), a keystone species of the savanna. Populations of the birds are declining due to habitat loss. The hornbill's diet consists primarily of termites and fruit. A critical component of termite digestion is chitin deacetylase, an enzyme whose mutation rate is a model parameter. The other model parameter is population size, N. In the results of the simulation study shown in these graphs, there is no selection, and the mutation rate is fixed. Although both population size and mutation rate are fixed, randomness results in the five different outcomes shown in each graph.

1. A population of snails that has striped and unstriped individuals has recently moved into a new region. Birds break the snails open by dropping them onto the rocks. The birds eat the bodies of the snails and leave the shells. In one area, researchers counted both live snails and broken shells. The data are summarized below. Number of Snail Shells Striped Shells Unstriped Shells Snails living snails broken (dead) 264 296 486 277 snails a) Analyze the data. Which form of snail (striped or unstriped) is more likely to be caught by the birds for food? Explain how you know. b) Suggest a hypothesis to explain what is happening to the snails. c) Predict and explain how the frequencies of striped and unstriped individuals in the population might change over many generations.

Options are a. Hybrid offspring. b. Speciation c. Adaptive radiation. d. Mechanical isolation.
3. Can the populations make hybrid offspring? Is there evidence that individuals from the popula- tions interbreed to make hybrid offspring? If so, are the offspring plentiful, healthy, and able to reproduce? Example: Lions and tigers don't normally mate in nature, but in captivity they sometimes produce hybrid offspring. These offspring are rare, short-lived, and unable to reproduce. Evidence: Healthy offspring Offspring are rare or less likely to reproduce No Consider the evidence together. Do you think the populations make healthy hybrid offspring? offspring N/A 1 2 3 4 5
