100
This note-taking style is a modified paragraph style. You don't need to use complete sentences.
What is the running text style?
100
A branch of science dealing with classification of living organisms.
What is systematics?
100
He is known as the father of modern taxonomy.
Who is Carl Linnaeus?
100
What was the title of Michael Hood's lecture?
Biodiversity.
100
The three levels of biodiversity are:
Species diversity, genetic diversity, and ecological diversity.
200
This note-taking method consists of listening and then writing in points in an organized pattern based on space indention.
What is the outline (note-taking) style?
200
What is the ecotone concept?
The boundary between two discrete environments (i.e., between seashore and sea).
200
This philosopher suggested that organisms can be ranked on a scale of being.
Who is Aristotle?
200
What were the three main parts of Hood’s lecture? Explain each briefly.
1) Classifying organisms = framework/basis for classifying species 2) Tree of Life = Basic branches (focus is not rich diversity) 3) Assessing Diversity = Focus on natural systems
200
Michael Hood argues that this is unappreciated.
Beings in scale of being have been big, charismatic but unappreciated is rich diversity of tiny things.
300
The subject of attention is the central image in this style. This style is great for visual learners.
What is mapping?
300
What is the main difference between taxonomy and phylogeny?
Taxonomy is about classification; phylogeny is about evolutionary relationship.
300
He wrote to the Royal Society of London about his observations on the “the little white matter” between his own teeth. He is considered to be the father of microbiology.
Who was Antonie van Leeuwenhoek?
300
What are the three domains in biological classification introduced by Carl Woese?
Archaea, bacteria, and eukaryota.
300
What is the extinction vortex? Explain briefly. What key factor drives the vortex?
The extinction vortex is a downward spiral and is unique to small populations. The small population is prone to changes that draw it into a vortex toward smaller and smaller numbers, thus accelerating their decline. The key factor that drives the vortex is the loss of genetic diversity.
400
This method divides your paper into 3 different sections: the note-taking area, the cue column, and a summary.
What is the Cornell method?
400
What is species richness and what is species evenness?
Species rich(ness) is the number of species in a community. Species even(ness) is the relative abundance of species.
400
Who is Lynn Margulis and what did she propose?
She advanced the serial endosymbiositic theory, which offers a plausible explanation for the evolution of eukaryotes (eukaryotic organelles).
400
Where is species richness highest? That is, in what kind of regions? And why?
Much of it is located in tropic or subtropical “hotspots.” These regions are close to water.
400
Why should we care about biodiversity?
Because there are benefits to species diversity and genetic diversity. Species that are threatened could provide crops, fibers, and medicines for human use. The loss of species means the loss of genes. And what happens with loss of genetic diversity? If population becomes extinct, then that entire population has lost genetic diversity. Why is that important? Because it’s detrimental to the overall adaptive prospects of a species.
500
What note-taking style would be most effective if using one's computer to write in-class lecture notes?
A mixture of all styles.
500
What is the Shannon-Wiener diversity index and what does it do (what’s its purpose)?
It’s a diversity index used to measure diversity (via data). It integrates both species richness and species evenness into single comparable measure or number. This measure of diversity is most commonly applied to manage natural systems.
500
Who is Laura Katz and what does she work on?
She studies the principles of eukaryotic evolution through phylogenetic reconstruction. To put it another way, She works on characterizing evolutionary relationships among eukaryotes.
500
What is ecosystem resilience and perturbance, and how does that relate to Hood’s examples of species evenness?
Ecosystem resilience is the capacity of an ecosystem to tolerate perturbance (or disturbance) without collapsing into a qualitatively different state. It’s the ability of a system to return after certain perturbance. In the example of the forest, if the species is too uneven, then if it’s subjected to perturbance, you lose that one individual, then you lose that species.
500
What is the current issue in biodiversity?
The role of phylogeny: not all species are equally related to each other, which brings up issues in conservation. How do we incorporate evolutionary relatedness into objective measures? How do we use phylogenetics in biodiversity?
