Ecological Relationships
One species benefits and other is neither harmed nor helped
What is commensalism?
This method, often used to estimate population size, involves capturing, marking, and then releasing individuals, followed by a second capture
What is mark-recapture sampling?
The study of the history of life on earth as based on fossils
What is palaeontology?
The complete disappearance/extermination of a species
What is extinction?
Sunlight, water, soil pH, soil salinity, soil compaction, chemicals like pesticides, soil degradation, temperature
What is abiotic factors
This term refers to the number of individuals of a particular species in a specific area, often measured during ecological surveys.
What is abundance?
Provides visual records of the past ecosystems in Australia that generally depicted plants and animals.
What is Aboriginal rock paintings?
Introduction of contaminants into the natural environment
What is pollution?
A community where abiotic and biotic factors interact
When studying a transect, this tool is commonly used to divide the line into smaller sections for more detailed analysis of species diversity.
What is a quadrat?
Ice cores contain small bubbles of this gas, which scientists analyse to understand past atmospheric conditions.
What is carbon dioxide?
The increase in global temperatures caused by human activities has created selection pressure for species to adapt to this environmental factor.
What is climate change?
A noisy miner bird that lives in your suburb hunts for insects among the plants in your garden and builds a nest.
What is an ecological niche
This sampling technique, often impractical for large or mobile populations, involves counting every individual of a species in a given area to obtain an exact population size.
What is a complete census (or complete count)?
The specific example of a painting found in West Kimberley depicting megafauna and the thylacine (Tasmanian tiger).
What are the Bradshaw Paintings?
The process where humans use animal breeding and plant breeding to selectively develop particular phenotypic traits
What is selective breeding?
Increased evolutionary diversification
What is a consequence of symbiosis?
Allows for an accurate reading or data of the timeline of what organisms lived when and where and the environmental conditions at the time.
What is radiometric dating?
This is used to understand the change of Earth's atmosphere from anaerobic to aerobic
What is banded iron formations?
Overexploitation, habitat loss, and climate change have led this species of rhinoceros, native to Africa, to the brink of extinction.
What is the White Rhinoceros
