- Which statments are correct? Question 25 options: Species diversity tends to increase with evapostranspiration Species diversity tends to increase with when parasitism is low Species diversity tends to increase with island area Species diversity tends to be higher when disturbance frequency is low Species diversity tends to increase with decreasing latitudeCA least tern ENDANGERED ANIMAL is CA least tern questionbases on the bird CA least term Reasons for Endangerment Explain the various factors that have led to this species’ current plight. Expand on these points individually, based on your species’ unique story. Domino Effects As we’ve learned, species are not islands unto themselves; they are integrated with many other organisms in trophic relationships, mutualisms, competition, etc. How is the absence of this species (or its lowered population size) likely to impact the other members of its habitat? (If findings specific to this point are available, please include them – otherwise, I’m asking you to speculate based on what you’ve learned about the biology of this organism.) Conservation Efforts Discuss past, current, and proposed efforts to conserve this species. Are these strategies effective? Are they realistic? What is the outlook for this organism?A rain forest habitat is located in an equatorial area with a warm, wet climate. Nearby is a savanna, where the climate is equally warm but much drier. Species diversity is much higher in the rain forest. Which rain forest habitat characteristic most likely explains this difference? O More disturbances, leading to rapid species turnover O More complex habitat structure, enabling greater food availability O More complex habitat structure, enabling greater niche specialization O Fewer disturbances, leading to rapid population growth of a few species O Fewer open spaces, leading to inability of organisms to leave the habitat
- Four of the following are characteristics that make some species especially vulnerable to ecological and biological extinction. Select the exception.

In addition to using various sampling methods to estimate species abundance, they observe the feeding patterns of dhe organisms. O Deseribe TWO sampling methods which the students could use to entimate the abundance of plant species in the area (a) (i1) Deseribe ONE method they could use to collect data on the mobile animals which inhabit the area.
- Biodiversity: Values & Threats 1. In terms of the number of species in various taxonomic groups, what types of organisms represent thegreatest diversity on our planet? And how do we know we’re not “done” cataloging all of life on earth? 2. When scientists try to estimate the number of species that actually exist on earth today, why is thefigure so variable? 3. Describe the global biodiversity patterns found in relation these parameters:Latitude Precipitation Elevation 4.

Use examples to support each of your statements.Which of the following statements related to classifications of rarity and extinction is TRUE? A species with an extensive geographic range and large local populations cannot be vulnerable to extinction. O Once species are the list of endangered species, they can never recover. O Species that are the most vulnerable to extinction have small population sizes, broad habitat tolerances, and narrow geographic ranges. O The majority of bird species that have gone extinct were those restricted to islands.Which of the following best describes the trend of biodiversity on the Earth's surface? * O It decreases towards the equator It increases towards the equator O It remains the same throughout the planet O It is not affected by the change in latitude Which is NOTa characteristic of a biodiversity hotspot? * O High species biodiversity High urban development O High endemic species population O High susceptibility to habitat destruction
- WRITE ABOUT A THEME: INTERACTIONS In Batesianmimicry, a palatable species gains protection by mimickingan unpalatable one. Imagine that individuals of a palatable,brightly colored fly species are blown to three remote islands.The first island has no predators of that species; the second haspredators but no similarly colored, unpalatable species; and thethird has both predators and a similarly colored, unpalatablespecies. In a short essay (100–150 words), predict what mighthappen to the coloration of the palatable species on each islandthrough time if coloration is a genetically controlled trait.Explain your predictionsSpecies in Two Communities Community 1 Community 2 E E E E £ Which statement best describes these two communities in terms of species richness, relative abundance, and biodiversity? о о O Both communities have the same species richness; however, community 2 has a higher relative abundance in all but one species and community 2 also has greater biodiversity than community 1. Community 1 has a dominant species, but has the same species richness, relative abundance, and species diversity as community 2. Both communities have the same species richness and biodiversity; however, community 1 has a higher relative abundance in all but one species when compared to community 1. Community 2 has a higher species richness, relative abundance, and species diversity when compared to community 1.
