Chapter One Ecology – the study of the many interactions in the world around us - body of knowledge concerning the economy of nature‚ investigation of the total relations of the animal both to its biotic and abiotic environment - concept developed by Ernst Haeckel in 1900s - The study of the interactions of organisms with one another and with their environment - not “the ecology” (wouldn’t say protect “the physics”) - not Environmental Science – study of how natural world works Ecological

APES Notes – Chapter 8 Community Ecology: Structure‚ Species Interactions‚ Succession‚ and Sustainability I. Appearance and Species Diversity A. The structure or spatial distribution of a community or ecosystem can be described by: a. Physical Appearance : relative sizes‚ stratification‚ and distribution of its population and species b. Species Diversity or Richness : the number of different species c. Species Abundance : the number of individuals of each species d. Niche Structure : the

Evolution as a theory * Theory- in science‚ a well substantiated explanation of some aspect of the natural world Evolution- the accumulation of inherited genetic changes within populations over generations * Does not refer to changes that occur in an individual within its lifetime * Not limited to speciation that may only occur over long periods of time * Can occur over a few generations‚ and is most commonly expressed as an adaptation to a changing environment or the change in allele

91 Chapter 5 Sources of plant nutrients and soil amendments A large number of diverse materials can serve as sources of plant nutrients. These can be natural‚ synthetic‚ recycled wastes or a range of biological products including microbial inoculants. Except for microbial inoculants (biofertilizers)‚ all of these contain one‚ two or several plant nutrients in readily or potentially available forms. A certain supply of mineral and organic nutrient sources is present in soils‚ but

Bioinformatics – is the application of computational methods to the storage and analysis of biological data Linkage Map – maps the location of several thousand genetic markers on each chromosome Physical Map – Expresses the distance between genetic markers‚ usually as the number of base pairs along the DNA Metagenomics – DNA from a group of species (a metagenome) is collected from an environmental

The evolution of plants has resulted in increasing levels of complexity‚ from the earliest algal mats‚ through bryophytes‚ lycopods‚ ferns to the complex gymnosperms and angiosperms of today. While the groups which appeared earlier continue to thrive‚ especially in the environments in which they evolved‚ each new grade of organisation has eventually become more "successful" than its predecessors by most measures. Probably an algal scum formed on land 1‚200 million years ago. In the Ordovician period
