4.5 + 6 + 7 Taxonomy Biodiversity Flashcards
1
Q
What is a species?
A
Similar organisms with similar morphological and genealogical features capable of producing fertile offspring
2
Q
Why is courtship behaviour necessary?
A
Species specific therefore prevents species interbreeding
3
Q
What is the taxonomy system?
A
Domain Kingdom Phylum Class Order Family Genus Species
4
Q
How can we clarify evolutionary relationships?
A
- Genome sequencing High % of similar DNA - Comparing amino acid sequences Similar species have similar amino acid sequences - Immunological comparisons Similar antigens
5
Q
What is species richness?
A
The number of different species within a community
6
Q
Why might an index of diversity be more useful?
A
Accounts for number of members of species not just raw number
7
Q
What is the equation for index of biodiversity?
A
N(N-1) / sigma n(n-1)
N total number of all species
n number of organisms in one species
8
Q
What effect do farming practices have on biodiversity?
A
Reduce it
