What effects could species extinctions have on human societies in years to come? In spite of many tools and data sources, biodiversity remains difficult to quantify precisely. proposed as good proxies for the diversity and integrity of ecosystems, since they are key elements of the biomass, structure and functioning of ecosystems and can be used as indicators of habitat quality (Vallecillo et al. Water is not organic material and inorganic material is usually relatively insignificant in terms of mass. I tell the students that we are going to be using an organizer to help us learn and remember what the word "biodiversity" means. A natural increase rate of 1% will enable a human population to double in 70 years. International scientific collaboration is important in the conservation of biodiverse regions. The area of land and water required to support a defined human population at a given standard of living. Join Bill Nye as he explores environments and ecosystems in a search of biodiversity. Outline the factors used to determine a species’ Red List conservation status. A habitat or a group of related habitats can be considered an ecosystem. The Gaia hypothesis (developed by James Lovelock and named after an ancient Greek Earth goddess) compares the Earth to a living organism in which feedback mechanisms maintain equilibrium. Habitat definition is - the place or environment where a plant or animal naturally or normally lives and grows. 2. The maximum number of a species or “load” that can be sustainably supported by a given environment. Now known to be potent greenhouse gases. Habitat destruction is a process in which the natural habitat is rendered functionally unable to support the species present. Habitat ACRONYMS AREAS COUNTRIES MARINE TERMS DEFINITION Habitat means the place or type of site where an organism or population naturally occurs. It extends from the upper part of the atmosphere (where birds, insects and wind- blown pollen may be found) down to the deepest part of the Earth’s crust to which living organisms venture. A simplified description designed to show the structure or workings of an object, system or concept. ​The ability to assess changes to biodiversity in a given community over time is important in assessing the impact of human activity in the community. Less economically developed country: a country with low to moderate industrialization and low to moderate average GNP per capita. Even more important would be to estimate turnover of biodiversity, not just point estimates in space or time. This greater variety of habitats permits species that are only found in specific habitats to occur in large areas and permits species that require multiple habitats to … Paul Andersen explains the importance of genetic variation within a population. However some might argue that technologies e.g. We'll bring you back here when you are done. The environment in which a species normally lives. Usually known as halocarbons and first identified as depleting the ozone layer in the stratosphere. Non-living natural resources that depend on the energy of the Sun for their replenishment; for example, groundwater. The habitat diversity hypothesis (Williams, 1964) proposes that the increase in species richness in large areas relative to small areas arises because large areas have a greater variety of habitats than small areas. The release of pollutants from a single, clearly identifiable site; for example, a factory chimney or the waste disposal pipe of a factory into a river. Species that usually concentrate their reproductive investment in a small number of offspring, thus increasing their survival rate and adapting them for living in long-term climax communities. ENDANGERED (EN) – when it is facing a very high risk of extinction in the wild. The gain by producers in energy or biomass per unit area per unit time remaining after allowing for respiratory losses (R). … ESS Topic 1.1: Environmental Value Systems, ESS Topic 2.2: Communities and Ecosystems, ESS Topic 2.3: Flows of Energy and Matter, ESS Topic 2.4: Biomes, Zonation and Succession, ESS Topic 3: Biodiversity and Conservation, ESS Topic 3.1: Introduction to Biodiversity, ESS Topic 3.4: Conservation of Biodiversity, ESS Topic 4: Water and Aquatic Food Production Systems and Society, ESS Topic 4.1: Introduction to Water Systems, ESS Topic 4.3: Aquatic Food Production Systems, ESS Topic 5:Soil Systems and Terrestrial Food Production Systems and Society, ESS Topic 5.1: Introduction to Soil Systems, ESS Topic 5.2: Terrestrial Food Production Systems and Food Choices, ESS Topic 5.3: Soil Degradation and Conservation, ESS Topic 6: Atmospheric Systems and Society, ESS Topic 6.1: Introduction to the Atmosphere, ESS Topic 7: Climate Change and Energy Production, ESS Topic 7.1: Energy Source and Security, ESS Topic 7.2: Climate change – Causes and Impacts, ESS Topic 7.3: Climate change – Mitigation and Adaptation, ESS Topic 8: Human System and Resource Use, ESS Topic 8.1: Human Populations Dynamics, ESS Topic 8.4 Human Population Carrying Capacity, Topic 2.7: DNA Replication, Transcription and Translation, Topic 3.5: Genetic Engineering and Biotechnology, Topic 5.3: Classification of Biodiversity, Topic 6.3: Defense Against Infectious Disease, Topic 6.6: Hormones, Homeostasis and Reproduction, Topic 7.2 Transcription and Gene Expression, Topic 8: Metabolism, Cell Respiration and Photosynthesis, Topic 9.1 Transport in the Xylem of Plants, Topic 9.2 Transport in the Phloem of Plants, Topic 11.1 Antibody Production and Vaccination, Topic 11.3: The Kidney and Osmoregulation. , causing world temperatures to be warmer than they would otherwise be when you are done area is dependent many...
