EXPERIMENT 6 Arthropod Diversity ( 30 MARKS) BIOL 1P92 Winter 2022 Name: Hareemah Ali Lab Section #: 12 Date: 28.4.22 Enter in the number of arthropod species identified and counted from the meadow and forest sites in both tables below. Use these results for your calculations on the next few pages. If a species was not found in a sample and therefore not counted, denote it as “---” . RESULTS: Meadow Species Number of individuals Acarina (mites/ticks) --- Araneida (spiders) 1 Chilopoda (centipedes) --- Coleoptera (beetles) 1 Collembola (springtails) 1 Diplopoda (millipedes) --- Diplura (diplurans) --- Diptera (flies/mosquitoes) --- Hemiptera (true bugs) --- Hymenoptera ( ants/bees/wasps) 2 Isopoda (woodlice) 51 Protura (proturans) --- Thysanura (silverfish) --- Unidentified (arthropods only) --- RESULTS: Forest Species Number of individuals Acarina (mites/ticks) --- Araneida (spiders) --- Chilopoda (centipedes) --- Coleoptera (beetles) --- Collembola (springtails) 1 Diplopoda (millipedes) 2 Diplura (diplurans) --- Diptera (flies/mosquitoes) --- Hemiptera (true bugs) --- Hymenoptera ( ants/bees/wasps) --- Isopoda (woodlice) 24 Protura (proturans) --- Thysanura (silverfish) --- Unidentified (arthropods only) --- Page 1 of 5

EXPERIMENT 6 Arthropod Diversity ( 30 MARKS) BIOL 1P92 Winter 2022 Calculations Follow the equations and sample calculations in the lab manual to help you complete the diversity calculations. You do not have to show your calculations. Only give your final calculated values in the spaces below. The number of decimal places required for each calculated value is indicated. RESULTS: Meadow 4 marks Species Richness (S) *whole number* S = 5 Simpson’s Diversity Index (D) *three decimal places* D = 1.207 Shannon Diversity Index (H) *three decimal places* H = 0.420 Evenness (E) *three decimal places* E = 0.261 RESULTS: Forest 4 marks Species Richness (S) *whole number* S = 3 Simpson’s Diversity Index (D) *three decimal places* D = 1.267 Page 2 of 5

So by the results it can be seen that the diversity for both ecosystems does differ. 3. Give at least two factors that could contribute to the difference (or lack of difference) in arthropod species diversity associated with the meadow and forest samples. 5 marks Answer: Forests are surrounded by trees while meadows are surrounded by grasses and variation in biotic and abiotic factors like soil type, climatic change, availability of sunlight, temperature impacts the arthropod communities relations to plants in these two ecosystems. Review Questions 7 marks- 0.5 marks each Highlight the correct answer from choices shown in bold or fill in the blank: 1. Organisms of the same species that share a gene pool and live the same area is referred to as a community / population . A community / population refers to different species living in the same area. Where these organisms live is called a habitat / niche . Their role in this environment is called a habitat / niche . 2. An ecology / ecosystem includes the community / population of plants and animals plus the physical environment. The plants and animals are the abiotic / biotic components while the physical features, such as soil type and water availability, are the abiotic / biotic factors. All communities / ecosystems make up the biome / biosphere . A biome / biosphere consists of large land mass with a distinct climate and specific species. An example would be: grassland______ 3. Place the following terms ( ecosystem, population, organism, biome, community, biosphere) in the order of biological organization or hierarchy starting with the most general and ending with the most specific. Answer: organism, population, community, ecosystem, biome, biosphere Page 4 of 5
