Measuring Abundance: Transects and Quadrats
www.hawaii.eduTransects and quadrats are two ecological tools that allow us to quantify the relative abundance of organisms in an area. To track changes over time, it is important to be able to quantify changes in abundance. Also, learning these techniques will give students the tools necessary ...

www.marine.usf.edumeasure. Band transects are larger sample areas created using a PVC pole and a shorter tape measure. These band transects are laid perpendicular to the main transect. As with the quadrats, selected species are counted along these band transects. Roving fish counts are used to monitor all the fish sited within ten meters of the transect line.

gen.uga.edubiodiversity study of organisms in one local habitat: plot studies and line transects. A transect is a long, narrow sampling area, while a plot study is a square area that can be divided into subplots. Transects extend over a longer portion of a study area than a plot does, resulting in a larger sample of different plant species.

scholar.harvard.edusmoothly at the mita boundary, I focus exclusively on the portion that transects the Andean range in southern Peru. Much of the boundary tightly follows the steep Andean precipice, and hence has elevation and the ethnic distribution of the population changing discretely at the boundary. In contrast, elevation, the
