biodiversity Flashcards
what is genetic diversity and what is the importance of it
the diversity of genetics in an area
gives the ability to resist+ recover
what classifys a biodiversity hotspot
- 1500 ednemic vascular plant species
- loss of 70% of natural habitat
the scales of measuring biodiversity
- temporal scale (measurement over time)
- Spacial scale (space being occupied
species richness?
species eveness?
Amount of different species
distribution of species
why classify species? 3 reasons
- to organise info
- investigate pasterns in relationships between organisms
- assist in international communication
What are the levels of classification//taxa?
kpcorfgs
Kingdom, phylum, class, order, family, genus species
classifying Characteristics?
Physical Characteristics
Methods of reproduction
Molecular sequences, (DNA, Genes)
Clade and monophyletic
- a taxomic group that contains all of the descendants of a common anscestor
- describes organisms grouped together as a clade (this cladogram is monphyletic)
biome?
ecosystem?
Biome: an area catagorised by major variation in vegetation, climate, topography, soil type.
ecosystem: area which there are interactions between environment and community.
Community?
Habitat?
Community: Living organisms in habitat + environment
(same species, same place, same time)
Habitat: area in ecosytem where organisms live, feed reproduce
abiotic and biotic factors?
Abiotic: a non-living factor within an ecosystem (landscape, weather etc)
Biotic: living factors within an ecosytem (plants, animals)
Intra species?
Inter species?
Intra: a species that help eachother (ants, wolves)
Inter: 2 species working together
collaborate
-members of the same of different species work together to benfit all
symbiosis and 3 ways it occurs
-long term relationship in an ecosytem with two or more organisms
parasitism= +- (ticks, fleas)
mutualism= ++ (clownfish and sea anenome)
Commensalism= + o (remora fish on sharks)
