Concept explainers

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.

Figure 18.23 Which of the following statements is false? Punctuated equilibrium is most likely to occur in a small population that experiences a rapid change in its environment. Punctuated equilibrium is most likely to occur in a large population that lives in a stable climate. Gradual speciation is most likely to occur in species that live in a stable climate. Gradual speciation and punctuated equilibrium both result in the evolution of new species.

ResiliencySpecies richnessBiodiversityGamma diversity words to match it with: number of species in an environment, considers number of habitats and total species number among them, combination of species richness and species eveness, same as species eveness, high probability of recovery to original state, high probability of disruption.If you do not understand the text based question, use the image below.
f you determine that 2 similar organisms are unable to interbreed, and you therefore classify each as a different species, which species concept are you using? The ecological species concept The morphological species concept The phylogenetic species concept The biological species concept
If the phylogenetic species concept (PSC) were used to define species, rather than the biological species concept (BSC), how might that change the estimates of species diversity (numbers of species) on a worldwide basis? True or False: Estimates of species diversity are likely to change if the PSC is used. In particular, one would expect the number of species to increase. This is because individuals from divergent allopatric populations that can potentially interbreed would belong to the same species under the BSC. These same organisms would be classified as members of different species under the PSC.
if you determine that 2 similar organisms distinctly different ways of interacting with other species and their environment, and you therefore classify each as a different species, which species concept are you using? The morphological species concept The biological species concept The ecological species concept The phylogenetic species concept
Primates are examples of: density-dependent species density-independent species r-selected species K-selected species
What is the importance of endemic hotspots to biodiversity conservation? A. Endemic hotspots contain many species found nowhere else, so the conservation of a small amount of area will protect many species. B. Endemic hotspots have the highest species diversity, so their conservation will protect the most species. C. Endemic hotspots are those that contain species vital to human existence, ssuch as medicinal species, and therefore humans rely on these areas the most. D. Endemic hotspots are where speciation rates are thegreatest, so the conservation of those areas will likely lead to the formation of many species in the future. E. Endemic hotspots have very low ecosystem stability, therefore require more protections to avoid extiction.
Which of the following best describes the biological significance of genetic diversity between populations? A) Genes for traits conferring an advantage to local conditions are unlikely. B) Diseases and parasites are not spread between separated populations. C) Genetic diversity reduces the probability of extinction. D) The population that is most fit would survive by competitive exclusion.

Another ecologist reported a diversity index value of 1.511 in a different community nearby the one you studied. This community is _ diverse than the one you calculated. Please see the attached image to get a better grasp of the question. How to Calculate Biodiversity and Ecology College Biology 2 Advanced Concepts Background Information In the Shannon index, p is the proportion (n/N) of individuals of one particular species found (n) divided by the total number of individuals found (N), ln is the natural log, Σ is the sum of the calculations, and s is the number of species... Species Evenness Species evenness takes into account the number of species and the relative abundance of species in a community. Several indices have been proposed. Two of the commonly used measures of evenness are the Shannon index (H) and the Simpson index (D). Question 2: What is the Shannon diversity index value for this community? What is the species evenness for this community?
