A group of individual organisms very similar in appearance, anatomy, physiology, biochemistry and genetics. Members are able to interbreed freely to produce fertile young
1 of 36
Habitat
The place where an organism lives
2 of 36
Biodiversity
The variety of life - the range of living organisms to be found
3 of 36
Random Sampling
Studying a small part of the habitat and assuming it contains a representative set of species that can be applied to the whole habitat. Sample sites must be chosen at random
4 of 36
Tullgren funnel
Devise for collecting small animals from leaf litter. Shine above leaf litter in the funnel and animals should drop down into the collective jar below.
5 of 36
Species Richness
the number of species present in a habitat
6 of 36
Simpsons Diversity index
A formula used to measure the diversity of a habitat that takes into account both species richness and evenness
7 of 36
Biological Classification
The process of sorting living things into groups.
8 of 36
Taxonomy
The study of the principles of classification
9 of 36
Phylogeny
The study of evolutionary relationships between organisms
10 of 36
Natural Classification
Grouping things according to how closely related they are. It reflects evolutionary relationships
11 of 36
Prokaryotes
Have no nucleus e.g bacteria and cyanobacteria
12 of 36
Protoctists
Include all organisms that don't fit into the other four kingdoms. Many are single celled some multicellular
13 of 36
Fungi
Organisms that are mostly saprophytic. Consist of a mycelium with walls made from chitin
14 of 36
Plant
Multicellular organisms that gain their nutrition from photosynthesis - autotrophic
15 of 36
Animals
Heterotrophic multicellular eukaryotes
16 of 36
The eight taxa
Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species in
17 of 36
Binomial System
Uses two names to identify each species - genus and species name
18 of 36
Dichotomous Key
Uses a series of questions with two alternative answers to help identify a specimen
19 of 36
Variation
The presence of variety - of differences between individuals
20 of 36
Genetic Variation
Caused by differences between the genes and the combinations of genes or alleles
21 of 36
Continuous Variation
Variation in which there is a full range of intermediate phenotypes between two extremes
22 of 36
Discontinuous Variation
Variation in which there are discrete groups of phenotypes with no or very few individuals in between
23 of 36
Adaptation
A feature that enhances survival and long term reproductive success
24 of 36
Xerophytic
Plants that are adapted to living in very dry conditions
25 of 36
Natural Selection
Selection by the environment of particular individuals that show certain variations. These individuals will survive to reproduce and pass on their variations to the next generation
26 of 36
Speciation
The formation of a new species
27 of 36
Allopatric Speciation
Geographical barrier prevents effective interbreeding between individuals of two populations e.g on the Galapagos islands
28 of 36
Sympatric
Reproductive barrier may arise due to a biochemical change the prevents fertilisation or a behavioural change e.g a courtship dance not recognised. Or a physical that means the sexual organs are no longer compatible between two groups
29 of 36
Evolution
The gradual process by which the present diversity of living organisms arose from simple primitive organism that were present about 4000 million years.
30 of 36
Extinction
The death of the last individual in a species
31 of 36
Conservation in situ
Conserving a species in its normal environment
32 of 36
Conservation ex situ
Conserving an endangered species by activities that take place outside its normal environment
33 of 36
CITES
Convention on International Trading in Endangered Species of Wild Fauna and Flora. Overall aim is to ensure that international trade in specimens of wildlife does not threaten their survival
34 of 36
Convention on Biological Diversity
Dedicated to promoting sustainable development
35 of 36
EIA
Environmental Impact Assessment - a procedure to assess the likely significant effects that a proposed development may have on the environment
