  • 3.3 Alpha-diversity

    Hi guys, welcome to the forth lecture of course Biological Diversity Theories Measure and Data Sampling Techniques. Today we will talk about alpha diversity. There are many kinds of diversity. Alpha diversity is just one of these. It’s the diversity in individual or sample unit. Beta diversity is another kind.…

    Hi guys, welcome to the 30 lecture ofthe course Biological Diversity Theories, Measures and Data sampling techniques. Today, I will explain you the sampling techniques to analyze and measure biodiversity. There are different samplic techniques,we start to analyze the terrestrial vertebrae, so the first thingthat is very important to know…

  • 3.1 Analysis and measure of biodiversity

    Hi guys, welcome to the 11th lecture of my course, Biological Diversity Theories, Measure, and Data sampling techniques. Today I will explain you how to analyze, and measure biodiversity First of all, we need to start to understand what is a community. We have some different possibilities. One of them…

  • 2.5 Gaia and biodiversity

    Hi guys, welcome to the tenth lectureof the course: Biological diversity, theories, measures andsampling data techniques. Today, I will talk to you about Gaia andbiodiversity. Gaia hypothesis was firstly proposed bythe Russian scientist Vladimir Vernadsky. The idea is that Earth is a perfect planet for life. But according to the…

  • 1.4 The distibution of biodiversity in macroscale

    Today, we will talk about the distribution of biodiversity. Two main processes for coexistence have been proposed. The first one is the avoidance of competition, and the second one is phenotypic plasticity. So there are three main patterns toexplain biological diversity, speciation, extinction, and dispersal First of all I would…
