Select a South Africa plant and produce an information sheet. This can be any plant, perhaps a garden plant or medicinal plant, and your information sheet should provide information on the plant and including the following:

 

•Name and classification of plant (from family to species)

•Photographs (images from internet will be fine, remember to add your source)

•Description (what does the plant look like?)

•Distribution (where does the plant occur in South Africa?)

•Ecology (anything interesting, e.g. pollinators)

•Red List status (this can be found at <span style="color: rgb(23, 41, 119);">http://redlist.sanbi.org/</span>)

•Uses

•References (a full list of references following Harvard Style. Remember to do in text referencing that corresponds with this list)


Is cutting field a biotic or abiotic factor?


I have a ecological research proposal and im trying to write it right now but a term in the question is confusing me. I have been given a plan lay out of sorts and in the background section it says 'Here you should explain the ecological context to the research you are planning'. My research proposal question is 'What influence has human activity had on seagrass meadows'. I obviously don't expect anyone to write it for me I just don't understand what the term ecological context means?

 (4) Almost every lecture in this course focused on a different animal behaviour. Choose your favourite and tell me about the adaptive basis of this behaviour. In particular

Favourite behaviour: Gazelle stotting 

 

1. Name a benefit (B) of this behaviour. What is a cost (C) of this behaviour? 

2. Choosing one personality category, how would this behaviour vary among individuals? 

3. Describe two ways human induced, rapid ecological change can impact this behaviour. 

4. How can this behaviour be used as an early-warning indicator of population threat?     

5. How can knowledge about this behaviour be used to facilitate the successful colonisation of restored or recovering habitat?
