Lab 10 Endangered Species - Karner Blue Butterfly

1.     State the scientific name and common name of your organism, its taxonomic Order, and taxonomic Family.

There are several endangered butterflies, one such butterfly is known as the Karner Blue Butterfly (Lycaeides melissa samuelis) in the taxonomic order of Lepidoptera and taxonomic family of Lycaenidae.

2.     Include two photos illustrating the organism in its natural setting.



3.     Explain this organism’s ecosystem role.

The Karner blue butterfly lives in oak savannas and pine barren ecosystems.  This area or region is located in the northeastern United States.  The area includes the states of New Hampshire, New York, Michigan, Wisconsin, Ohio, Indiana, and Minnesota.  The Karner Blue larvae eat the wild lupines (Lupinus Perennis), which is unique to this region. 

4.     Describe at least two ecological services this organism provides for humans and other species (at least two ecological services for each, humans and other species).

There is several ecological service that the Karner blue provides.  Some of them include the caterpillars feeding only on the wild lupine plant and adults feeding on the nectar of flowering plants.  In the ecological service of the caterpillars eating the wild lupine, from getting of our control through over growth.  This is also associated with the aiding in a healthier density of the wild lupine.  As for the nectar, the adult Karner blue helps to improve the nectar richness.  Another service is maintain a higher level of nectar species diversity.  The decline of the Karner blue is also an indicator to us that the pine barren habitat is also endanger.   

5.     Include and explain in words, a chart or graph showing population of this organism over time.

Here is a chart illustrating the loss of the Karner blue butterfly in Albany New York in a ten-year period during development of a mall and surrounding areas that encroached on the butterfly habitat.


6.     State how the equation I = PAT is involved in the threats to this organism.

The formula to determine impact on the environment known as I=PAT or I (impact) = P (population) x A (affluence) x T (technology) is great formula to illustrate the things directly impacting the Karner blue butterfly.  First, we know the I or impact is the butterfly population has significantly decreased over the years and is now endangered.  Then onto the other side of the equation, the P or population of the country has increased, including the in the northeastern part of the country.  The population increase has negatively impacted the butterfly multiplied with the impact from the A or affluence of the people.  The affluence is the people’s need for consumption of goods and services.  This could be reflected in chart above relating the mall development in Albany.  Finally, the multiplication of T or technology is derived from the damage done through technologies that are supplying the consumption such as cars, trucks, busses, trains, and factories.  All three of these things multiplied illustrate a major impact on the existence of the butterfly. 

7.     Referring to figure 9-3 in your textbook, determine and describe the characteristic(s) that endanger(s) your species.

The characteristics that endanger the Karner blue butterfly is a low reproductive rate in that is produces many eggs, but only a small percentage may survive.  Another characteristic example that is endangering this butterfly species is the limited or fixed migratory pattern.  The Karner blue does move very far from its habitat and when it does, it is in a small fixed area. 

8.     Determine if this organism is affected by density dependent and/or density independent factors. Explain the situation in some detail.

In general density dependent factors are more biological related versus density independent factors, which are more physical factors like weather or chemical pollutants introduced.  As for the Karner blue organism it is most impacted more by the density dependent versus the independent.  The biological factors that impact the butterfly are the loss of the biological habitat through population growth and development.  Although something might be said for independent factors such as pollutants effecting the environment and causing global warming.  This seems like it might start as an independent, but then turn to a dependent factor. 

9.     Describe the feedback loops involved.

The negative feedback loop that describes the decline of the Karner blue butterfly is the butterfly feeds of the pine and other vegetation of the area, but many of these species are becoming less and less due to population and development of homes and business.  As the plant species that the butterflies feed off of, so then the butterfly population declines.  As the butterfly population declines, then the diversity and richness of the nectar also dissipates. 

10.  Describe how global climate change is affecting or is predicted to affect this organism’s habitat.

Various studies have indicated the heat stress on Karner blue butterflies.  There is an ideal temperature that the butterfly migrates and flies within the given habitat.  As global climate change takes place rather up or down, but mostly higher temperatures dramatically negatively impact the butterfly.  By the butterfly not flying, makes it a target for predators and prevents the reproduction process. 

11.  Referring to the three principles of sustainability, why should humans care about this organism?

According to article published by the U.S. Wildlife and Fish Services, we have lost more than 500 species since the early 1600’s.  This is a dramatic change from a few million years ago, where it is estimated that we only lost about 3 species a year.  The bottom line rather it 3 species a year or 100 species a year, species are going extinct, meaning gone forever.  Biological diversity is critically important to the retaining a certain balance in nature.  As we have been learning this semester in Environmental biology the balance of our ecology is fairly fragile and keeping the balance should be a high priority.  As we lose each species, our overall environment is impacted and the quality of life is negatively effected.  As referenced earlier the loss of the butterfly indicates a weakening of the ecosystems, that butterfly depends on for its own survival.

12.  Name and give a two or three-sentence description of two individuals (not groups) who are champions of this organism.

Candee Lane Elsworth of the Toledo Zoo is an advocate that has given presentation on the Karner blue butterfly and its importance to our ecology.

Louis Perrotti is the director of the conservation programs for the Rogers Williams park zoo in Rhode Island.  One of the program Louis is responsible for is the Karner blue butterfly conservation program.

13.  Name and give a two or three-sentence description of two individuals (not groups) who do not want this organism protected, at least not in their “own backyard.”

Unfortunately, I was not able to identify individuals that do not want the Karner blue butterfly protected.  I would have to indicate the groups that may not want the butterfly protected might be land developers that do not want the area they would like to develop protected for the butterflies and thereby preventing development.  Also, maybe another threat to the Karner Blue might be butterfly collectors.  Due to the rarity of the Karner blue, this makes the collecting of it that much more valuable. 

14.  Include a link to one recent scientific article or story about this organism that was written or produced in the last year.

Here is an article written just a few weeks ago about the Karner blue butterfly.  The article talks about the Discovery Center in Albany, New York having a display of the Karner Blues as they go through the metamorphosis.  The exhibit will have several hundred Karner Blues going this life changing process.  The center will also use this week to highlight the issues surrounding the need to protect and grow awareness about the Karner blue butterfly. 

15.  State the Precautionary Principle in your own words.

Basically the precautionary principle is an action that should be taken before an action takes place that could do harm.  There is no need to wait for something to be inflicted then react or more related to science, there is not need to wait for scientific findings that something may cause harm.  The public consensus can act without of the support of the scientific community, if it deems something to be harmful.

Lab 9 Curtis Pond Dam Removal


In 2012, the Curtis Pond Dam was removed; this was a first in series of dam removals on Ipswich River Watershed.  The dam is located in Middleton, Massachusetts on the Boston Brook.  The dam was built in the 1930’s and was used for the Curtis Brother’s sawmill.  The sawmill remained in existence till it’s closing in 1960’s.  In the 1970’s the town of Danvers acquired the dam and later had it evaluated to be unsafe. Danvers in partnership with the Massachusetts Department of Environmental Protection and private landowners moved forward in 2012 to remove the dam. 

According to the American Rivers Organization “the dam was removed to restore in stream flow, migratory fish passage, and improve river habitat.”  It is believed that this project will greatly help some species currently being considered to be placed on the endangered species list, like the American Eel and River Herring.  An additional motivation to removing the dam is to reduce future liability and upkeep for the property owners, as the dam has become run down.  Removal of the dam has improved life to the surrounding area.  The remaining threat to the surrounding ecosystem remains other dams along the Ipswich River Watershed.  The area has been studied and continues to be studied for future dam removals that will benefit rivers, streams, and brooks. 



Lab 8 Fearsome Frogs

There were many things that surprised me about the fearsome bullfrogs in Arizona.  First, I did not realize that they were initially introduced to Arizona as prey to be hunted, but the idea never really took off.  Secondly, the range of species that bullfrogs consume surprised me.  If you would have asked me prior to watching the video on the frogs, I might have guessed they consumed smaller species like grasshoppers, crickets, etc.  I would not have guessed that they consumed poisonous tarantulas, scorpions, snakes, turtles, etc.  Lastly, I was surprised by the negative impact they are playing on the ecosystem through mass consumption of species.  There is a fear of elimination of some species like the leopard frog due to the bullfrogs eating habits. 
            My proposed solution to slow the impact of the bullfrogs on the ecosystem would be to return to the original plan, bullfrogs for game and hunting purposes.  Initially, it was the hope by the government that bullfrogs would provide an additional species that hunters could hunt, but it never took off.  Somehow, I would return to the marketing and promotion of bullfrogs, as something to be hunted and consumed.  It seems like Arizona is a state full of people that like to hunt, so promote the need and opportunity to hunt this small game and help the ecosystem. 

            In doing some additional research there are several species that are considered invasive, in that they are causing problems by their presence in the local ecosystem.   According to the University of Arizona Cooperative Extension Office the crayfish is similar to the bullfrog in its havoc that it is playing on the ecosystem.  The crayfish is a species introduced about thirty years ago.  It was introduced to provide life bait for fishing and to control aquatic weeds.  The crayfish are big eaters, much like the bullfrog, they consume a great deal of plant life, native fish eggs, frogs, etc.  Arizona now currently has laws prohibiting the transporting of crayfish within the state to try to prevent the spread of this invasive species.  Here is the article that I helped in the research of invasive species in Arizona.  http://extension.arizona.edu/sites/extension.arizona.edu/files/pubs/az1481e.pdf
