Total Endemic Species for Plants, Mammals, Birds, Reptile, Amphibian and Fish

/in /by

Biodiversity hotspots are one conservation strategy used to direct funds to areas in the globe that have the highest biodiversity and are most threatened. To qualify as a biodiversity hotspot an area must have more than 1,500 endemic plant species (0.5% of the world’s total of 300,000) AND have experienced a 70% loss of habitat.

1) Each person will select a biodiversity hotspot (sign list in class) and use the Conservation Internationl Biodiversity Hotspots website as a key starting resource to find the following information to bring into class to write on the board and share orally.  USE THE WEBSITES POSTED UNDER ASSIGNMENTS/CH 1&2/HOTSPOTS to get started:

a) Overview: Vital Signs Table: Total Endemic Plants, Human Population Density (can copy and paste the table, but you must use an in-text citation)

b) Species: Diversity and Endemism Table: Total Endemic Species for Plants, Mammals, Birds, Reptile, Amphibian and Fish (copy and paste the table, but you must use an in-text citation)

c) Threats: List top three threats with evidence of why and how they impact the hotspot

d) Projects: What will take you the most time to find and evaluate is specific information about conservation actions in the hotspot region. You will want to include who (government, nonprofit, international agency) is doing what (fence, antipoaching squad, protected area, farming project) at what cost (dollars) with what measure of success (#species saved over time, increase population size over time, area protected increased, % invasives reduced) and then analyze if this is what is needed based on the human impact and biodiversity loss data you have collected.

2)  Your research results  with in-text citations AND your list of at least 10 scientific references using  APA.  You must physically have in your property and have read every source you cite.  REMEMBER YOU ARE SUMMARIZING KEY FACTS IN YOUR OWN WORDS.

  1. Given the fact that there is no cure for Huntington chorea, how would you counsel clients?
  2. What would you do if faced with the decision?
  3. How might it affect family function?
  4. What about insurance and employment issues-could there be ramifications?

Number 2 discussion: Altered cellular and tissue BiologyDiscuss: 

  1. You have studied several genetic disorders that alter cells. Keeping in mind that these types of disorders are inherited from one or both biological parents, consider the pros and cons of whether there should be laws requiring genetic studies on both parents either in preparation for having children or if the parents give birth to a child with a genetic disorder.
  2. In this module and in your text, you learned about the toxic effects of alcohol (ethanol) and other chemicals on cells and tissues. Consider for a minute why, when people are highly aware of the negative effects of such use on the body’s cells and tissues, they continue abusing the substance.
  3. 3. Based on the theories of aging, discuss some lifestyle factors that might have a positive effect on aging. What are some of the pros and cons of making these lifestyle changes, from your perspective. Please send answers to my email nosenpeter@yahoo.com Thanks

Describe the historical pattern of growth of the worldwide human population since our origin. Include in this historic overview the changes that have happened technologically, medically, culturally and nutritionally to result in major population changes over time. Relate the growth of the human population to our ecological footprint and explain the idea of limits to population growth known as the carrying capacity. Relative to carrying capacity, what may result from unbridled continued growth of our population? How does the size of the human population contribute to environmental degradation? Why must we take the human population size into account when we attempt to develop environmental restoration projects?
