The Importance of Biodiversity. Biodiversity definition. Australia’s Biodiversity. What is an endemic species? Biodiversity is dependent on size, as well as biotic and abiotic factors present and their interactions. Biodiversity at different levels: ecosystem (communities interacting with each other and the environment) species (variety of organisms in a given location/biological species concept) and genes (range of alleles in a species population gene pool). Measuring Biodiversity. Species richness, species evenness, biodiversity index calculations i.e. Simpson’s Diversity Indices. Spatial and temporal comparisons. Strategies to Maintain Biodiversity. Australia’s Biodiversity Conservation Strategy 2010–2030 presents a long-term view of the future and the actions that need to be implemented to conserve biodiversity. Australia’s Biodiversity Conservation Strategy 2010-2030 A 100-year Biodiversity Strategy for WA International agreements about biodiversity encourage international cooperation in the protection of unique locations, including World Heritage sites, for example, Shark Bay, Great Barrier Reef Biodiversity hotspots, (locations and reasons for being declared a hot spot) for example, south west WA International migration routes and areas used for breeding, for example, by birds, whales, turtles, whale sharks.

10 Apr 2 Cycling of Matter The biotic components of an ecosystem transfer and transform energy, originating primarily from the sun, and matter to produce biomass; and interact with abiotic components to facilitate biogeochemical cycling, including carbon and nitrogen cycling; these interactions can be represented using food webs and biomass pyramids. Importance of recycling. Soil Cycling Carbon Nitrogen Cycle Water Cycle Phosphorus Cycle Biological Magnification (biomagnification and bioaccumulation) Chapter 4 Set 4.5 Case p.95 Q1-7 Set 4.6 Biozone WS 237 Nutrient Cycles Biozone WS 239 The Carbon Cycle Biozone WS 240 The Nitrogen Cycle Biozone WS 238 The Hydrologic Cycle Biozone WS 243 Biomagnification of Chemicals 2/4 Easter Monday 3/4 Easter Tuesday 4/4 – 6/4 Year 12 Retreat 5/4 – 6/4 Year 10 and 11 Geography Camp 11 Apr 9 (Final week of Term 1) Population Dynamics The dynamic nature of populations influence population size, density, composition and distribution. Ecosystems have carrying capacities that limit the number of organisms (within populations) they support, and can be impacted by changes to abiotic and biotic factors, including climatic events. Population definition. Populations are described by size, density, composition (age, male/female) and distribution. Populations controlled by abiotic and biotic factors. Carrying capacity definition. Carrying capacity is dynamic and is influenced by the abiotic and biotic factors. Ecosystems have carrying capacities that can limit the number of organisms that they can support. Population effects when near carrying capacity. Carrying capacity varies either long term or term. Population growth. Population Age Structure – Population Pyramids. Measuring Populations – growth, distribution, abundance. Task 3: Population Dynamics (5%). Class discussion and research. Interpret a range of scientific and media texts, and evaluate processes, claims and conclusions by considering the quality of available evidence; and use reasoning to construct scientific arguments.

Environmental strategies: including revegetation and control of introduced species. Management strategies: including protected areas and restricted commercial and recreational access. Identification and classification of an ecological area as a conservation reserve also requires consideration of the commercial and recreational uses of the area, as well as Indigenous Peoples’ usage rights.

13 Oct 8 (First week of Term 4) Plant Transport Systems In vascular plants, transport of and mineral nutrients from the roots occurs via xylem through root pressure, capillary action (adhesion and cohesion of water molecules), transpiration; transport of the products of photosynthesis and some mineral nutrients occurs by translocation in the phloem. Plant structure and function: Vascular and non-vascular plants. Composition of vascular tissue. Transport of and nutrients from roots to leaves. Structure and function of xylem, phloem and root hair cells. Function of roots and shoots in transporting water. Factors influencing water and nutrient movement (adhesion/cohesion, transpiration). Translocation and evidence for it (Aphids). Chapter 12 Set 12.1 Experiment 12.1 Set 12.2 Plant and Animal Nutrition Internal Transport 8/10 Staff PD Day 9/8 Year 11 Mass
