Transects are used to investigate how the distribution of organisms changes across an area.
What is a "belt transect"?
What is Systematic Sampling with Transects?
"Transect sampling is a systematic ecological method used to measure how the distribution of species changes across an environmental gradient."
Why are quadrats used in ecological fieldwork?
Why should random sampling be used when placing quadrats?
Which sampling method is best for investigating how the distribution of plants changes across a path?
Measuring Distribution
Lay out a tape measure (the transect line) across the area.
Place quadrats at regular intervals along the line (e.g., every 2 metres).
Record the species present and abiotic factors (like light or soil pH) at each point.
Transects are perfect for looking at a change from a shaded area to a sunny area.
