Answer:

Complete the following problems using the equation:

Students are not required to memorize this formula but must know the meaning of the symbols:

D = diversity index

N = total number of organisms of all species found

Σ = the sum of

n = number of individuals of a particular species

D is a measure of species richness. A high value of D suggests a stable and ancient site, and a low value of D could suggest pollution, recent colonization or agricultural management. The index is normally used in studies of vegetation but can also be applied to comparisons of animal (or even all species) diversity.

Example: A lake contains 934 brown trout, 733 smallmouth bass, 34 catfish, 2003 carp,

234 steelheads, and 32 northern pikes.

Fish

Number (n)

n(n-1)

Brown Trout

934

934 x (934-1) = 871422

Smallmouth Bass

733

733 x (732) = 536556

Catfish

34

34 x (33) = 1122

Carp

2003

2003 x (2002)=4010006

Steelheads

234

234 x (233)=54522

Northern Pike

32

32 x (31)=992

Total (N)

3970

= 5 474 620

= 3970 x 3969 = 15 756 930

D = = 2.88

Simpson’s Diversity Index – Practice Problems

When comparing two or more samples, the location with the larger D has a greater amount of diversity. Note that a higher total population does not indicate higher diversity.

An area of the Black Forest in Germany contains 134 pitch pines, 24 douglas firs, and 53 red pines.

A meadow contains 1532 chestnut oaks, 342 black cherry trees, 12 white ash trees, and 1022 yellow birches.

Your backyard contains 12 fleas, 34 aphids, 84 ants, 93 beetles, and 1 butterfly.

An African National Park contains 15 lions, 94 giraffes, 1000 wildebeests, 50 elephants, and 5 hyenas.

Mindo (a city in Ecuador) has 832 toucans, 392 red headed barbets, 3 golden headed quetzals, 500 tanagers, 899 parrots, and 50 white capped dippers.

Answer the following questions in your workbook:

Calculate Simpson’s diversity index for each location. Include the table in your workbook.

Distinguish the differences in diversity between two locations listed above.

Explain what may lead to those differences.

Outline the significance of the Simpson’s Diversity Index. You may refer to the following online resource and your textbook to help outline your ideas - http://www.countrysideinfo.co.uk/simpsons.htm

In contrast to growing microtubules, shrinking microtubules ............. Group of answer choices have strong lateral interactio
Otrada [13]

Answer:

have curved protofilaments at their plus ends

Explanation:

Microtubules are polymers of tubulin proteins that function as the cytoskeleton of eukaryotic cells. Microtubules are dynamic structures that can grow and shrink at a rapid rate. During this process, tubulin subunits can associate and dissociate at the plus end of the protofilament. Tubulin subunits bind to two GTP molecules, one of which is hydrolyzed to GDP after assembly. When microtubules are unstable, protofilaments curl outwards because GDP-bound tubulin has a weak affinity (thereby curving it) and disassemble. The dynamic stability of microtubules is regulated by a feedback loop: when microtubules shrink, free tubulin concentration increases and microtubules start to grow. As microtubules grow, free tubulin concentration decreases and the rate of GTP-tubulin addition also decreases.
