Biodiversity Lab Exercise Biodiversity Lab Exercise BACKGROUND Biodiversity is critical in any self-sustaining environment. Complex and diverse ecological systems are made up of many organisms and a huge variety of interactions. Simple ecosystems have few organisms, few interactions, and are fragile. All ecosystems, whether diverse or sparse, involve an intimate interaction of living things with their abiotic environment. Variety or diversity in an ecosystem increases the chance of survival in a changing world. The Earth is losing its biodiversity at an exponentially increasing rate. Humans simplify ecosystems for many reasons: to increase the agricultural base, to make way for cities and industrial zones, or for aesthetic reasons, such as making lawns and gardens. This practice has direct effects upon many abiotic factors within an environment. The air temperatures found in cities, for instance, are usually significantly higher than that in surrounding, non-urbanized areas. Such cities are said to produce a heat island effect . An area’s biodiversity has profound effects upon the physical and biological makeup of an ecosystem. 8 - +

Biodiversity Lab Exercise Figures from: London Metropolitan University 1987 “Heat island effect” Biodiversity Conservation India Limited 2009 “Heat island effect” OBJECTIVES In this experiment, you will: Determine how animal diversity changes in different environments. 1* Work with your classmates to compare biodiversity in areas with different plant patch sizes. 2* Determine how local temperature changes with height in different habitats 3* Interpret your results. MATERIALS LabQuest and Temperature Probe Meter stick Field flags Field satchel Clipboard Soil trowel PROCEDURE 1. You will be working in groups of 4-5 today. Please remember that your lab reports must be written in groups of 2-3 students. 2. Your instructor will show you two different sites (behind Millea Hall) where you need to make your measurements: Site A (complex) and Site B (simple). 3. Please be careful to be safe and avoid poison ivy (shiny, irregular shaped leaves of three). DATA COLLECTION 1. Using the meter stick, measure out a one-square meter area at Site A. Mark the 4 corners with flags.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
