What is biodiversity |
The variety of all lifeforms |
|
|
What is a species |
A unit of diversity that consistently differs from other such groups |
|
|
What is taxonomy |
The practice of classifying diversity |
|
|
What is the Biological Species Concept |
Species are groups of interbreeding populations that cannot reproduce with other groups. |
|
|
What is reproductive isolation |
Dont or can't reproduce together to produce successful offspring |
|
|
What is prematng isolation |
Dont breed in nature despite ability to produce successful offspring |
|
|
What is postmating isolation |
Mate together but don't produce successful offspring |
|
|
What is Andreas Vesalius known for |
Compared anatomy of humans and other animals. Realised that humans have little unique features, but share many with other animals |
|
|
What was the uniformitarianism theory |
Chanhes in earth's crust during geological history have resulted from the action of continuous and uniform processes. |
|
|
What was Carl Linnaeus known for |
He placed animals and plants in a classification system based on similarities |
|
|
What was Erasmus Darwin known for |
Speculating on the origins of life and that species could change. |
|
|
What did Lanark recognise |
That species could change because of needs imposed by their environment |
|
|
What was Wallace know fir |
The same theory as Darwin. Proposed the theory of evolution via natural selection. Survival of the fittest. |
|
|
What is survival of the fittest |
Those best suited to their environment are more likely to survive |
|
|
What is natural selection |
Only the fittest will survive and breed, whereas those less suited to their environment will be less likely to survive and breed |
|
|
What is adaptation |
Species become better suited to their environment through the effects of natural selection across generations |
|
|
What is fitness |
The relative reproductive success of an individual |
|
|
What is weather |
Short term changes in temperature, clouds, precipitation, humidity in a specific location |
|
|
What is climate |
Average weather over a specific time period in a specific location |
|
|
What is climate change |
Change in typical or average weather in a specific location |
|
|
What are some examples of first order climate controls |
Solar activity, solar system geometry, earth's internal heat budget |
|
|
What are some examples of second order climate controls |
Golabl distribution of continents and oceans, tectonic cycles |
|
|

Microbiotheria, probascidea, and sirenia |
|
|
What are some sources of data |
Remote sensing, sensor networks and citizen science |
|
|
What is remote sensing |
obtaining information about an object or area from a distance |
|
|
Wjat are some problems with remote sensing |
Resolution, clouds, reflections, surface data only, cost, data size, processing |
|
|
What are the two types of connecting sensors |
Wired : cameras Wireless: short and longer range (mobile phone), point-to-point and ad hoc |
|
|
What is evolution |
Change in the heritable characteristics of biological populations over successive generations |
|
|
What is chytrid and what impact does it have on wildlife |
A waterborne fungus that infects frog skin, it has caused extinctions work wide |
|
|
where humans classified prior to Linnaeus system |
No. Linnaeus was the first to classify humans just as any plant or animal |
|
|
List the four major causes of extinction and species decline |
1. Habitat loss and change 2. Introduced species 3. Disease 4. Over harvesting and hunting |
