What are the three types of biodiversity

• Species diversity

• Evolutionary diversity

• Ecosystem diversity

• Metabolic diversity

• Genetic diversity

Biodiversity

• Biodiversity refers to the variety of life on planet earth

• Species diversity: How many organisms exist on earth.

• Ecosystem diversity: How many distinct ecosystems exist on a given place

• Genetic diversity: The diversity that exists within members of a species

  
  

Multiple Choice

Name of the branch of biology that groups organisms based on characteristics

• Ecology

• Phylogeny

• Taxonomy

• Endocrinology

Taxonomy

• Branch of biology that classifies organisms based on characteristics

• A group of related organisms is a taxon (Taxa in plural)

Multiple Choice

The broadest classification level (taxon) is...

• Domain

• Species

• Class

• Genus

• Family

Classification

• There are 8 classification levels (taxa)

• Domain, Kingdom, Phyllum, Order, Class, Family, Genus, Species

• All of them are based on a series of characteristics, going from the broadest (most shared) to the most specific (least shared)

Multiple Select

The binomial name is made out of the____ and the ______

• Genus name

• Class name

• Family ame

• species name

Binomial name

• The basis of the classification system is the species name

• It is comprised of the Genus name and the species name

• The name is always in italics, with the genus starting in Capital letter

Multiple Select

These are all reasons why Dichotomous keys are a great tool

• They are specific

• They ara a Classification tool

• They are an identification tool

• Yes/no questions

• They are open ended

Dichotomous keys

• Tools for identifying specific organisms based on their characteristics

• They are a series of questions to which there are only two possible answers

Multiple Choice

What is a cladogram?

• A tree diagram that represents the evolutionary history of a group

• A group consisting of ralated organisms

• A speciation event

Phylogeny and cladograms

• Phylogeny: The history of the evolution of a species or group

• Cladistics – A method of classifying organisms into groups of species called clades

• Cladograms – Tree diagrams that represents the evolutionary history of a clade

Multiple Choice

Which two organisms are more related to each other?

• D,E

• A,E

• B,C

• C,D

• B,D

• Root – The initial ancestor common to all organisms within the cladogram.

• Nodes – A common ancestor that speciated to give rise to two (or more) groups

• Outgroup – The most distantly related species in the cladogram.

• The closer the organisms are in the cladogram, the more related they are

Multiple Choice

What is species evenness?

• The number of species found in a specific place.

• Number of individuals of a species present in a specific place.

• the abundance of one species related to the rest of the species in a community.

Species diversity

• Species richness: The number of species found in a specific place.

• Species abundance: How many individuals of a species are present in a specific place.

• Species evenness: the abundance of one species related to the rest of the species in a community.

• An ecosystem is more diverse if it has high richness and evenness

• More species, means more interactions, creating more stability

Multiple Choice

What is ecosystem connectivity?

• When ecosystems maintaining stability.

• When processes that happen in one ecosystem affect others

Ecosystem equilibrium & connectivity

• Ecosystem equilibrium: When ecosystems maintain internal stability

• Ecosystem connectivity; When the processes that happen in an ecosystem affect others

Multiple Select

What are the three main types of ecosystem services?

• Indirect services

• Direct services

• Regulation services

• Aesthetic services

Ecosystem services

• What ecosystems give to humanity

• Direct services: Things we receive directly from the ecosystem, like food or wood.

• Indirect services: Benefits we obtain when ecosystems function well, like production of oxygen.

• Aesthetic/ethical services: The value we get from ecosystems that can't be measured, like the feeling you get when looking at nature
