Journal Article- Plants of the Alpine Tundra and Change Over Tim ( BEST INFORMATION IN INTRODUCTION AND SUMMARY)

Journal Article- Plants of the Alpine Tundra and Change Over Time

( BEST INFORMATION IN INTRODUCTION AND SUMMARY)

Erin C.'s insight:

Currency: This journal article was written in June of 2012.
Relevance: It discusses alpine plants in British Columbia, as well as several mountain ranges within the area where the alpine tundra can be found. It also discusses a disconnect between the Canadian species and the American species due periods of climate change throughout world history. (Note: The article is rather long, and the introduction and summary provide the best information)
Authority/Accuracy: The journal entry was written by Kendrick L.Marr, Richard J. Hebda, and William H. MacKenzie. The field work and written materials was funded by the Royal British Columbia Museum and the British Columbia Ministry of Forests and Range. The article also came from a Gale database, and was therefore pre-screened for accuracy and authority.
Purpose: It was written to discuss why the disconnect exists between Canada and North America as well as discuss examples of specific plant species used as evidence for the conclusion.

We chose to include this source because it provides fascinating information on how biomes, specifically the alpine tundra, have changed over time. It highlights that with Earth's climate change comes change in the distribution of Earth's biomes.

Erin C.'s insight:

Currency: The website was written in 2002, but no other relevant websites gave the information needed as to why this biome is an important factor to humans.
Relevance: It gave specific information providing us the reason as to why this biome in particular should be carefully protected. The website also gave the average temperature of the alpine tundra and the species living there.
Authority/Accuracy: The author is Skip Walter who is a biology professor.
Purpose: The website was created for the purpose of giving the readers an overall gist of what the alpine tundra is actually like and also why it is important to us humans.

This source gave specific information as to why this biome is a necessity for humans. The tundra provides us with oil and mineral exploitations and contains massive amounts of carbon. If the carbons decompose, the concentration of carbon dioxide will continue to increase in the atmosphere bringing global warming closer.

Tundra Overview- Precipitation, Soil Characteristics, Animals and Plants

Science in Context
Erin C.'s insight:

Currency: The article was originally written in 2001, but it was recently updated on June 1, 2012.
Relevance: The article provided a summary of the characteristics of the tundra as a whole, and then distinguished between arctic tundra and alpine tundra. It illustrated the differences as well as similarities between the two biomes.
Authority/Accuracy: The author was Richard Robinson, and the article was published by Plant Sciences. It came from a Gale database, and was therefore pre-screened for accuracy and authority.
Purpose: The purpose of the document was to provide an overview of the characteristics, flora, and fauna of tundras. It was written in the style of an encyclopedia entry, and was meant to give the basic information.

World Biomes PDF- NPP of the Tundra and Brief Overview (pgs. 5-6)

Erin C.'s insight:

Currency: The document was created in 2013
Relevance: The document contains a graph comparing the net primary productivity of all biomes, including the alpine tundra, as well as a summary of the alpine biome. (Pgs. 5, 6)
Authority: The document was created by the Education Services of Australia.
Accuracy: The information regarding NPP and that found in the summary matched previous sources, however, the other sources did not mention the alpine biome while this one has a more complete list.
Purpose: The purpose of the document was to be a lesson plan for teachers of secondary students. It was meant to provide information over each biome as well as activities illustrating their differences.

Erin C.'s comment, December 8, 2014 8:44 PM
This document was included mainly because of the NPP graph which illustrates the relatively low levels in the tundra when compared with other biomes. The information pertaining to our biome is on pages five and six.

Alpine Biome- Climate, Animals and Plants, Human Impact, Locations/Map | The Alpine Tundra | Scoop.it
Erin C.'s insight:
Currency: The website is a long-term project, the Biome Project, of the faculty and staff of Marietta College Department Of Biology and Environmental Science, and has been constantly updated and adjusted as new information appears. Relevance: It has a specific page on the alpine biome, which includes maps, images from locations around the globe, an overview of the climate, indicator species, ecological notes, and threats. Authority: It was created and maintained by professors who teach Environmental Biology (Biology 102) and Ecology (Biology 318) at Marietta College. Accuracy: They have traveled around the globe to gather specific data about locations in various biomes, visiting locations from Thailand to Alaska. In addition all information came from the professors, who have spent years teaching the subject matter (This page contains their introduction to the Biomes Project: http://www.marietta.edu/~biol/biomes/project.htm) Purpose: Quoting the website,"The Biome Project is a long-term undertaking by the Department of Biology and Environmental Science at Marietta College. The goal is to produce web and intranet-based teaching materials that help our students achieve learning outcomes consistent with the College's core values which include emphasis on liberal learning, critical thinking, technology and international awareness."

The website includes specific information about the temperature in Alpine biomes. Allthough a definite range cannot be provided because there is so much variation in location, it describes a general rule for determining average temperature. It also provides a map showing the world distribution of the biome as well as specific locations across the globe. The page contains information on indicator plant species, animal species, and human threats as well.
