What does this graph tell us about plant species diversity and latitude? Closer to the poles, diversity decreases.   Species diversity does not vary with latitude.   Closer to the poles, diversity increases.   Nothing.

Which of these hypothetical species would be least impacted by climate change? An arctic seal A mid-elevation shrub in the temperate zone A coral in a tropical coral reef A wildflower found only on mountaintops An endemic orchid with a coevolved pollinator

If you compare species richness and evenness along the edge versus in the center of a tree farm and then make the same comparison for a rain forest, what would you expect to find? There would probably be a greater difference in richness but less difference in evenness between the tree farm and the rain forest. There would probably be a greater difference in evenness but less difference in richness between the tree farm and the rain forest. There would probably be about the same difference between the core and the edge in the tree farm versus the rain forest. There would probably be more difference between the core and the edge in the tree farm versus the rain forest. There would probably be less difference between the core and edge in the tree farm versus the rain forest.

Write a synthesis statement with a paragraph that follows. Hint: sampling are always below trees

The Lazy River Environmental Group is a group of fishermen and environmentalists that have worked to assess and clean up the pollution from an old factory on the Lazy River. One early study revealed that species on the river had absorbed pollutants from the water. Select the Pollutant Levels in Tissue, by Species dataset and follow the interactive to graph the data. Which statement(s) correctly describe the graph? (Check all that apply.) The two species with highest levels are both fish.The two species with highest levels are both fish. Turtles had a pollutant level about three times that of clams.Turtles had a pollutant level about three times that of clams. No invertebrate (excludes fish and turtles) had a level above 0.05 ppm.No invertebrate (excludes fish and turtles) had a level above 0.05 ppm. The fish species with the highest level was about three times the value of the fish species with the lowest level.The fish species with the highest level was about three…

Imagine you are a botanist. Below are characteristics of a never-before described plant species recently identified as part of the ‘All Taxa Biodiversity Inventory’ (ATBI).Organism 1Field Notes: Specimen collected from rocks on bank of streams from the Adirondack Park (NY). Plant growth form is more ‘prone’ than upright (plant seems to have little support).Laboratory Analysis:Body: Consists of three regions: light brown anchoring tissue (base of plant); Green vegetative area (middle of plant); Brownish-green, stalk-like structure bearing capsule at end (top of plant).Size: 8 cm in lengthChromosomal Analysis: Bottom two thirds of plant is haploid (chromosome # 10), while top third of plant is haploid (chromosome # 20).Lignin test: NegativeCuticle: PresentLeaves: Absent, though they do possess green photosynthetic structures. Contains chlorophyll a, b; B-carotenes; xanthophylls.Roots: Absent, though they do possess anchoring (possibly absorptive) structures.Stem: Absent, though they do…

Of the 50,000 species introduced into the United States, half are plants. Describe two ways in which non-native plants might be brought to a new environment. How might we help prevent non-native plants from establishing in new areas and posing threats to native communities?

How can you use your data to discourage or promote logging of natural forest for human consumption? If logging activities cause decline of species diversity, what alternatives do you propose to maintain the tree species diversity in natural forests?
