Concept explainers
a.
To describe: The factor (dispersal) that ecologists examine to understand the geographic distribution of a species.
Introduction: Biogeography is defined as the study that deals with the geographic distribution of ecosystem and species. The species distribution indicates the evolutionary and ecological interactions with biotic and abiotic factors. There are four factors used by ecologists in order to examine the geographic distribution of species, dispersal, habitat selection, behavior, biotic factors, and abiotic factors.
b.
To describe: The factors (habitat selection and behavior) that ecologists examine to understand the geographic distribution of a species.
c.
To describe: The factor (biotic) that ecologists examine to understand the geographic distribution of a species.
d.
To describe: The factor (abiotic) that ecologists examine to understand the geographic distribution of a species.

- Which of the following methods will provide information to an ecologist about both the size and density of a population? a. mark and recapture b. mark and release c. quadrat d. life tablearrow_forwardDifferentiate primary succession between terrestrial and aquatic ecosystem in terms of the following. a. pioneer community b. intermediate community c. climax communityarrow_forwardThe study of how habitat-type distribution across a landscape is known as: A. Landscape Ecology B. Evolutionary Ethology C. Population Biology D. Conservation Biologyarrow_forward
- Identify an ecological footprint and perform an analysis on the ecological footprint mentionedarrow_forwardDefine the three aspects of biodiversity: A. Genetic Biodicersity B. Species biodiversity C. Ecological biodiversityarrow_forwardDetermine if each statement is correct or incorrect: 1. Ecosystems with fewer numbers of species tend to be less stable. 2. Increasing numbers of species lead to more redundancy which is bad for the ecosystem. 3. More species mean more niche separation. 4. Species with a low resistance will also have low resilience. 5. Disturbances to ecosystems can be both naturally occurring and human caused. 6. Stresses to ecosystems are useful for removing weaker species and ensuring the strongest survive. 7. Bringing non-native species into an area to increase biodiversity makes the ecosystem more stable.arrow_forward
- choose the correct alternative on the biotic potential influences:a) the average number of offspring producedb) the size of the individualsc) mortalityd) migration ratearrow_forwardWhat are the economic, environmental and/or biological implications of the following scenarios? Give specific examples. a. Loss of biodiversityarrow_forwardDIFFERENTIATE the two factors of species diversity. (Species richness and relative abundance)arrow_forward
- Choose one of the following factors and explain how and why species richness varies with it: temporal variation, latitude, succession. Give a specific example.arrow_forwardWhich of the following statements best represents the productivityhypothesis regarding species richness?a. The larger the area, the greater the number of species that will befound there.b. Temperate regions have a lower species richness due to the lack oftime available for migration after the last Ice Age.c. The number of species in a particular community is directly relatedto the amount of available energy.d. As invertebrate productivity increases, species richness will increase.e. Species richness is not related to primary productivity.arrow_forwardClaim: O Complete the statement. Coral is a that affects the stability of an ecosystem. Reasoning: O Explain what a keystone species is and how your evidence supports your answer. O Explain how coral affects biodiversity and the stability of the ecosystem.arrow_forward
