Copy of Evolution Summative
Transcript of Copy of Evolution Summative
They may also be referred to as the
“the milkweed butterflies”. (MLMP, 2008)
They are the only organisms that eat milkweed due to it horrible taste.
When the monarch are in their butterfly state they pollinate milkweed flowers. Therefore they are considered pollinators.
Pollinators - organisms that help flowers and other plants reproduce. Why has a decline in the milkweed population, as a result of urbanization and pesticides, affected the migration
of monarch butterflies? What are Monarch Butterflies?
And how are they unique compared
to other organisms such as other
butterflies and birds? What is the significance of the Monarch butterfly migration? How does it differ from other migrations (such as other butterflies and bird migrations)? How does climate change affect Monarch Butterflies? How do humans contribute to the problem? How has urbanization and
pesticide affect milkweed?
What are the positives to
pesticide/herbicide? What is the importance of milkweed for the monarch butterflies? What is the relationship between the Monarch and the milkweed? Why has a decline in the milkweed population, as a result of urbanization and pesticides, affected the migration of monarch butterflies? Work Cited They are unique due to their migration length because they have the longest migration. (Arizona-Sonora Desert Museum, 2006)
They usually travel and stay in large bunches enough to cover a tree. Lives in North America due to the milkweed (MLMP, 2008)
They migrate during the cooler months; starting around late March or early April
It is the longest migration
(Hanson, Nguyen and To, 2012) During their migration they...
Receive moisture from low clouds
Drink water around rivers
Females leave egg under
(MLMP, 2008) Temperature affects the Monarch in many ways
however the two main ways are if the...
Temperature rises they mate
Temperature lowers they migrate
(Southwest Monarch Study, 2012) The climate continues to warm up there will be a buildup of butterflies in one area causing food shortages
Humans affect are the production of global warming by:
Building destroying natural homes
(MLMP, 2008) Extreme changes to environment
can kill off the milkweed because they grow in warm areas They are part of the food chain
There are 108 species of milkweed in North America and Monarch only eat/use 30 species (MLMP, 2008)
They help each other survive and reproduce.
Therefore they make a perfect match The decline in the milkweed population will affect the monarch butterflies because monarch butterfly depends on the milkweed for most of their life, for shelter, food and daily survival. (MLMP, 2008) If urbanization occurred there will be a decrease in the milkweed population and the monarch population and/or will put them in great danger. They migrate...
to certain mountains
the coast of California,
or British Columbia Monarchs follow warm, moist conditions and move northward in the spring (overwinter[ing])
(Hanson, Nguyen and To, 2012)
Overwinter/overwintering - spending the winter in a warmer region Due to their horrible bitter taste other organisms attempt to copy them using mimicry.
For example, the viceroy attempts to copy the wings of the monarch to trick it's predators into thinking it is a monarch so the predator will not eat it. (MLMP, 2008)
Mimicry - coping another spices in order to protect them from predators When human need space to build industries and other building, they may remove lands where milkweed grows. The positives of using pesticides and herbicides....
Kills any parasites
Kills any unwanted and harmful insects
Herbicides can destroy unwanted weeds or harmful plants
(MLMP, 2008) Milkweed-group: Asclepias
Milkweed grows in warm areas, such as deserts
(Southwest Monarch Study, 2012) Egg Milkweed Milkweed Monarch caterpillar Milkweed Monarch butterfly Predator Monarch butterfly "Danaus Plexippus." Danaus Plexippus. Government, June 2008. Web. 16 Nov. 2012. <http://www.mlmp.org/Resources/pdf/5431_Monarch_en.pdf> This website is created by the government, therefore it is reputable. The website content is filled with a lot of monarch butterfly information. I used this website because it was easy to read and follow. It had also contained various types of information I needed to know about my topic.
"Migratory Pollinators." Migratory Pollinators. Arizona-Sonora Desert Museum, 2006. Web. 16 Nov. 2012. <http://www.desertmuseum.org/pollination/monarchs.php>. This website is reputable because of the information I received about the website and its content. The website contains important information about monarch butterfly. I used this website because it was easy to read.
"Importance of Milkweed." Southwest Monarch Study. N.p., 30 Sept. 2012. Web. 19 Nov. 2012. <http://www.swmonarchs.org/milkweed.php>. This website is reputable because of the information I received about the website and its content. The website contains important information about milkweed. I used this website because it was easy to read and it contained pictures to follow along with. And this cycle continues for many generations.
Also, monarch butterflies use the toxins and poison from the milkweed in order to taste bitter/horrible to its predator, such as the blue jay, as seen before Monarchs migrate to warm temperatures where milkweed grows.
If there are no milkweeds they cannot survive and may die off.
If they are able to adapt to a different plant then the bitter tastes will disappear and the predators will eat them.
(MLMP, 2008) Using herbicides can destroy the milkweed, which is the host plant to the monarch.
On the other hand, using pesticides can backfire/majorly impacts the monarch butterflies due to its poison, causing helpless deaths of monarchs. (MLMP, 2008) The monarch and
