25 lis 2024 · Transects are lines laid out across a site that can be used to measure abundance and distribution across a habitat. Transects are useful for determining how species abundance and distribution might change along a gradient e.g. at increasing distances from a field margin or perpendicular to the water's edge on a rocky shore

18 sie 2021 · The distribution of a species describes how it is spread throughout the ecosystem; The abundance of a species is the number of individuals of that species; The distribution and abundance of a species in an area can be assessed using different practical methods: Frame Quadrats; Line and Belt Transects; Mark-release-capture
Transect - A transect is a straight line across a habitat that is used to make measurements and observations. Distribution - The distribution of a species is the geographical area in which a species can be found. Abundance - Abundance is the number of organisms of a species found within a habitat.
This Mathematical Skills Handbook is designed to accompany the OCR Advanced Subsidiary GCE and Advanced GCE specifications in Biology A and Biology B (Advancing Biology) for teaching from September 2015. OCR will update this document on a regular basis.

In the Population Dynamics Click & Learn, students explore two classic mathematical models that describe how populations change over time: the exponential and logistic growth models. Students learn about each model through an interactive simulator supported by introductory information and real biological examples.
