What is a line transect used for in ecology?

A line transect is a crucial method in ecology for mapping the distribution of organisms within a specific area. This technique involves laying out a straight line across a habitat and then surveying the organisms that are found at regular intervals along that line. By doing this, ecologists can gather quantitative data on species presence, abundance, and distribution patterns.

These measurements can reveal how different factors, such as environmental gradients or habitat features, influence where organisms are found. This approach is particularly useful for studying populations in situ and understanding spatial relationships between species and their habitats, which can inform conservation efforts and ecosystem management strategies. The other options focus on assessing different environmental parameters but do not specifically involve mapping organism distribution.
