Topic 3: Demecology – the ecology of populations The main idea: Note how mathematical models are used to examine variation in growth of a population. Lecture outline: 1. Statistic and dynamic characteristics of population. 2. Growth curves patterns: J-shaped curve and S-shaped curve 3. Population regulation: Density-dependent and density-independent factors. 4. Human population patterns: - Population numbers. - Demographic transition and structure - Population urbanization

Virtual Ecology Lab: Invasive Species Worksheet Learning Goal: To learn how an invasive species can affect an ecosystem. Prerequisite Knowledge: Before beginning this lab‚ you should be familiar with these concepts: the definition of invasive species the types of interactions that occur between different species in an ecosystem Introduction: Ecosystems are webs of intricately balanced interactions. But what happens when a new species is introduced that uses a disproportionate share of the ecosystem’s

1. Learned means having much knowledge and well – informed. Innate means already known or originating in. 2. Habituation – a decrease in response to a stimulus after repeated presentations a. Estivation – animals trying to escape things happening in their environment b. Imprinting – learning occurring at a particular age or a particular life stage that is rapid c. Hibernation – refers to a season of heterothermy that is characterized by low body temperature‚ slow breathing and heart rate‚ and low

Anthony Dove 72196 Introduction to New Zealand Ecology Assignment 1 Task 1 Ecology Ecology is the study of ecosystems and environment. The first definition of ecology was provided by the German zoologist Ernst Haeckel. Haeckel describes ecology as – ’The body of knowledge concerning the economy of nature - the total relations of the animal to both its inorganic and organic environment. ’(History of Ecology‚(n.d.)). A more complete and modern definition is given by

Biophysical Ecology and Pattern Recognition Abstract: This study was undertaken to investigate behavioral adaptations of a lizard‚ Lacertilia‚ to its environment. Twelve peeps‚ representing the lizards‚ were placed in a habitat with two microhabitats of different temperatures. Six peeps were placed in one microhabitat‚ and six in the other. The internal temperature of these “lizards” was measured over a period of 20 minutes to see if their body temperatures matched that of their environment and

Outline for Life History Section 1: Introduction to Life Histories Name the ways that a population can increase its overall growth rate. 1) Reduction in age at first reproduction 2) Increase number of progeny at each reproductive event 3) Increase number of reproductive events (and longevity!) 4) Increase in birth rate (b) 5) Decrease in death rate (d) 6) Decrease in generation time (T) 7) Increase in net reproductive rates (R0) What is the connection between age

“Deep ecology is a ecological philosophies that concerns itself with the current destruction of the Earth’s biosphere and the possibilities for the restoration of the planet’s life system” (Hathaway & Boff‚ 2009c‚ p.63). By contrast‚ Taoism‚ a ethical theory invented by Laozi in China tries to explore a ideal worldview in which everything is equally existed on the planet. Obviously‚ the debates on similarities and difference of basic worldview in Taoism and deep ecology have been continuing few decades
