What are traits that make a species vulnerable?

What are traits that make a species vulnerable?

This link will open in a new window

There are many reasons for the ever increasing number of extinction events that have happened in the last century. According to the International Union of Nature Conservation, extinction rates have increased as much as 53% since humans became a major player in global extinction events. Approximately 75% of vertebrates (not including fish) have disappeared since 1800, while only 80 species are known to have died out in the previous three centuries. Regardless of cause, whether it be human caused, or unfortunate tragedy, there are certain traits that a species can have that make them more likely to be vulnerable to extinction. To prepare for this forum, read about the eight most common characteristics that makes an organism more likely to go extinct.

What are some organisms that have gone extinct in recent history?

This link will open in a new window

Your task is to research and present an organism that has gone extinct in the last 50 years. To find an organism that interests you, peruse this expansive list of organisms. The format of this webpage is pretty terrible (you will have to scroll from side to side to see all the information presented), but it will help you find a species that interests you. You can choose your organism based on the reasons for extinction, region that it used to live in, or even just because it has a funny name! The columns that will aid in your search include:

  • Common name
  • Former distribution
  • Estimated extinction date
  • Causes of extinction

Notice at the bottom of the webpage there are tabs that separate out plants and animals, feel free to choose your organism from either list. Just be sure to pay attention to date of extinction, and focus on organisms that went extinct after 1965, or even better, pick one that has disappeared in your lifetime!

Research your chosen organism and create a new discussion post, addressing the following aspects:

Use the name of your chosen species as the post title.

Points will be deducted for duplicate entries (unless the time stamps on both posts are very close together, suggesting they were being written at the same time).

Present a brief synopsis of your species’ biology.

Discuss native habitat, other species the organism typically interacts, with including predators and competitors.

Identify the main reason that the species went extinct AND the aspect of it’s biology that contributed to it’s destruction.

Discuss if and how humans brought about their disappearance, as well as which one of the 8 characteristics that likely also played a role.

Include a picture to in your post.

(or at the very least a link to a site that has an image).

To receive full credit, you must:

  • Write in complete sentences that are thoughtful, well written, and free of typos.
  • Present a species that has not been previously reported on by a fellow classmate.
  • Address all parts of the forum topic.
  • Use vocabulary presented in the learning materials appropriately.
  • Create a discussion and reply to another discussion by 8:00 pm on Saturday of week 5 (7 days after week 5 module becomes available).

Student #1:

The snake river sucker is a fish that was located in the snake river in Wyoming. I was intrigued but this fish because of the name it was given. Its true name is the Chasmistis Muriei, the snake river sucker sounds much better to me though! The snake river sucker’s habitat is in fresh river water. It was only found in the Snake River, hence the nickname it was given. It became extinct in 1927 although the reasoning from the research I had done is different on every site on why. The website that we were directed to use said the causation of extinction was habitat modification, though another site stated the extinction reason is unknown. It was also found to be an epidemic to the Snake River. I had a hard time directly finding a picture of the fish because there are many other fish that are called “blank” river sucker from other rivers of course; they do generally all look similar.  I have added a site that has a few different sicker fishes to show examples. 

Because it was difficult to find an exact reasoning for extinction, I believe a lot of species go extinct because of human causation. Animals become threatened species or species of concern because of the decisions we as humans make. Involving pollution, eating animal products, and the use of plastic. Sadly if we don’t change the way we are living out normal lives many other endangered animals will start to diminish also

student#2:

Striped Rocksnail

This little snail known as the stiped rocksnail aka ( Leptoxis Vittata)  used to live on the banks of the Coosa river in Alabama. Its predators included the local fish in the area. This snail became extinct in 1990 when they built a dam on the river destroying it habitat. From the limited information I could find they used to use its secretion to treat skin problems. Here is a picture.

Antibiotic Resistance

Antibiotic Resistance

For many years, antibiotics have been effectively used to treat bacterial disease.

A growing concern for treating bacterial diseases is the evolution of antibiotic resistance by bacterial populations. Resistance means that a particular antibiotic is no longer effective in treating a disease. This resistance can be viewed as evolution of a new trait at the population level, which is resistance to an antibiotic.

Recommended: Click on the following links to review materials to increase your understanding of natural selection and antibiotic resistance.

Understanding Evolution

Antibiotic Resistance 

Focus your discussion on 1 of the following topics:

  • The use, overuse, and abuse of antibiotics are accredited with creating antibiotic-resistant strains of bacteria. Explain how this relates to natural selection.
  • Using a credible source, describe at least 2 of the things that people do (you can include individuals, doctors, health care professionals, hospitals, farmers, and so on) that contribute to this problem. Explain.
  • Are there things that you can personally do to reduce your risk or even to reduce the spread of these dangerous microbes?

Utilize at least 1 credible source to support the arguments presented in your post.

Human Organ Systems

Human Organ Systems

The human body is truly remarkable and is designed to function effectively. Organs are important structures composed of different tissues that facilitate specific functions within the body. Organs function as part of an integrated group of structures known as organ systems. These organ systems form the organizational units that are responsible for crucial processes necessary for sustaining life. Examples of organ systems include, but are not limited to, the cardiovascular system, the digestive system, the musculoskeletal system, the nervous system, the excretory system, the endocrine system, and the respiratory system. Even organ systems do not function alone. These systems work together, interacting with other organs in a functional network that keeps the body in balance. (Look up the term homeostasis in your text.) When homeostasis or the normal functioning of organ systems is disrupted, disease may develop, causing injury to the body or even death.

The following case studies detail an outcome associated with a disease or organ malfunction. Select 1 study to investigate further for your assignment.

Critically evaluate the information provided, and correlate it with the organ systems that are affected in the scenario. Use the information that you have gathered to answer the assignment questions that follow the case study. Present your work as an APA-formatted research report.

Recommended: In addition to the case studies, click on the following links to view materials to increase your understanding and enhance your analysis of the cardiovascular and respiratory systems.

How Your Body is Like a Factory 

How Lungs Work

Cardiovascular System

Case Study 1:

Atherosclerosis is narrowing of the arteries caused by the accumulation of fatty deposits on the arterial walls. On June 22, 2002, the St. Louis Cardinals were preparing for their upcoming baseball game against the Chicago Cubs. Concern arose when their prized pitcher, 33-year old Darryl Kile did not show up for practice. Soon after, he was found still in his hotel room where he had suddenly died in his sleep (New York Times, 2002). It was discovered that the cause of death was related to three of his coronary arteries being 80–90% blocked as a result of atherosclerosis (New York Times, 2002), which ultimately caused him to suffer a heart attack.

Answer the following questions in regard to this case study:

  • Why would atherosclerosis result in a heart attack? Provide a brief explanation based on how the heart functions.
  • How are arteries different from veins and capillaries? Describe the functions of both arteries and veins.
  • Vertebrates and some invertebrates have a closed circulatory system. Explain the advantage of having a closed circulatory system over an open circulatory system

Case Study 2:

Cigarette smoking remains the leading preventable cause of death in the United States, causing an estimated 438,000 deaths—or about 1 out of every 5 smokers—each year (National Cancer Institute, 2008).

Mr. Amos is 57 years old and has been smoking for the past 30 years of his life. A recent doctor’s visit revealed that Mr. Amos has stage 3 lung cancer, characterized by his symptoms of nagging chest pain, fatigue, coughing up blood, substantial weight loss, and increased carbon dioxide levels in his blood. The doctor informed Mr. Amos that had he quit his smoking habit several years ago, he would have reduced his risk for developing lung cancer later in life. Mr. Amos immediately began treatment for the lung cancer that had metastasized to his lymph nodes.

Answer the following questions regarding this case study:

  • What main components in cigarettes affect the respiratory system? Explain their effects on specific organs, cells, and processes in the respiratory system.
  • There are alternate mechanisms of transporting carbon dioxide (CO2) and oxygen (O2) in the blood. Explain how smoking might lead to increased levels of carbon dioxide in the blood.
  • Can smoking affect other organ systems of the body? Give specific examples, and briefly explain your answer.

Follow these guidelines for your paper:

  • Utilize at least 2 credible sources to support the arguments presented in the paper. Make sure you cite them appropriately within your paper, and list the references in APA format on your Reference page.
  • Your paper should be 2–3 pages in length, not counting the Title page, Abstract, and Reference page. In accordance with APA formatting requirements, it should be double-spaced and include a running head and page numbers.

Animal Kingdom

Animal Kingdom

Organisms are placed in taxonomic classifications based on differences and similarities of their traits. If you know what critical traits to look for, it is possible to separate any animal into a taxonomic category using a dichotomous key.

The common taxonomic categories are Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species (Specific Epithet). This assignment will explore the Phylum and Class categories.

The assignment document contains a table with nine images. The images are examples of nine different animal phyla: Porifera, Cnidaria, Nematoda, Arthropoda, Platyhelminthes, Annelida, Mollusca, Echinodermata, and Chordata.

  • In column 1, determine and list the correct Phylum name for each animal using the nine Phyla listed in your text.
  • In column 2, using the dichotomous key provided, determine the class for each animal. List all of the dichotomous key steps chosen when using the key to arrive at the class for each animal.
  • In column 3, the Classification Column, write the class name for each animal from the dichotomous key provided and your key steps.

First download U5 Animal Table 2018document.

Next, download the Dichotomous Keydocument.

Use the dichotomous key to determine the class category, as shown for each animal (picture), and write the class names under the Classification Column on the table.

For help on how to use the dichotomous key, download and review the document called How to Use the Dichotomous Key.

Angiosperm Adaptations

Angiosperm Adaptations

Angiosperms (flowering plants) are the largest Phylum in the plant kingdom Plantae. These plants have true roots, stems, leaves, and flowers. The roots grow into the soil to anchor the plant in place and take up water and nutrients. The leaves are above ground and act as the main organs for photosynthesis. Stems provide above-ground support for the plant and operate as conduits to move nutrients and water throughout the plant. Flowers contain the male and female reproductive organs of the plant.

Plants develop specialized roots, stems, leaves, and flowers to make them better adapted to their environment. With the anatomical features described above in mind, do some research to find an angiosperm that has modified leaves, stems, roots or flowers that are structurally different from the norm, do not function in the normal manner, or that function in an unusual manner. For example, a cactus has spines in place of leaves. The spines help reduce water loss that would occur through a large, expanded leaf in a desert environment, and they also help to prevent herbivory.

Recommended:

  • Browse through the pages in the following link to learn more about gymnosperms and angiosperms: Evolution of the Seed Plant.
  • Watch this video to learn more about modified roots, stems and leaves: Modification of Root, Stem and Leaf.

Complete all of the following steps:

  • Choose an angiosperm with at least 1 unusual organ, characteristic, modification, or adaptation.
  • Describe the anatomy (structure) and physiology (function) of the angiosperm you chose. 
  • Explain the unusual characteristic(s) or modification(s) and how it differs from the standard root, stem, leaf, or flower.
  • What benefit does the modification provide to the plant you chose? 
  • Research at least 1 other plant, or review posts made by your peers to devise a potentially advantageous new adaptation that would benefit your plant. 
    • Consider the environment, potential threats, and changing climate, and then come up with an adaptation that would further benefit your angiosperm. Explain the potential concern your plant will face and how your new adaptation would benefit the plant. For example, gypsy moth is an introduced species spreading west and south from New England. The caterpillars can strip all of the leaves from a maple tree but do not eat the waxy leaves of holly that produce a toxin, theobromine. If maple trees had waxy, toxic leaves like the holly, then they would be protected from these pests.

Utilize at least 1 credible source to support the arguments presented in your post.

Of the three steps in the strategy implementation phase, which do you think is the most important? Why?

PLEASE EXPLAIN WHETHER YOU AGREE WITH MY CLASSMATE RESPONSE TO THE ABOVE QUESTION AND WHY? (A MININUM OF 125 WORDS) 

Of the three steps in the strategy implementation phase, which do you think is the most important? Why?

       CLASSMATE’ MATE POST

I would place a little more emphasis on the budget.  I feel like although you have aligned all your strategies and put them in a position to start reaching the company goals, this isn’t going to be possible if you don’t have or haven’t looked at the budget.  With anything you want to do in life, you need to have the budget to make it happen.  If you put all these strategies in place regarding programs and tactics, and you haven’t properly reviewed your budget, you may have to go back and revise because you don’t have the proper budget to carry out the implementation strategies you have included in your plan.  Again, I think they all play an equal role overall; however, I think the budget is something that needs to be established before you even begin.  With any organization, you need to know what your left and right lateral limits in terms of spending before you are able to properly plan.  I know for me, being in the military, everything we do centers around the budget.  We can plan this big elaborate training exercise, and it all looks and sounds good, and it goes all the way up the chain to find out we don’t have the funding for it in our budget.  Had we known that from the beginning, we may have come up with an alternate plan to make it work within our means.
