Environment and Ecology Lecture 1 - Basics of Ecology

What are the key ecology concepts all Intro Bio students should learn?

Register Now. Ecology is the study of the relationships between living organisms, including humans, and their physical environment; it seeks to understand the vital connections between plants and animals and the world around them. Ecologists study these relationships among organisms and habitats of many different sizes, ranging from the study of microscopic bacteria growing in a fish tank, to the complex interactions between the thousands of plant, animal, and other communities found in a desert. Ecologists also study many kinds of environments. For example, ecologists may study microbes living in the soil under your feet or animals and plants in a rain forest or the ocean.

Ecology is the study of organisms, populations, and communities as they relate to one another and interact in the ecosystems they comprise. Ecology is the study of the interactions of living organisms with their environment. Within the discipline of ecology, researchers work at four specific levels, sometimes discretely and sometimes with overlap. These levels are organism, population, community, and ecosystem. In ecology, ecosystems are composed of dynamically-interacting parts, which include organisms, the communities they comprise, and the non-living abiotic components of their environment. Ecosystem processes, such as primary production, pedogenesis the formation of soil , nutrient cycling, and various niche construction activities, regulate the flux of energy and matter through an environment.

The First Law of Ecology: Everything Is Connected to Everything Else

Ecology is the study of how living biotic and nonliving abiotic parts of the environment interact with and depend each other. Guess you could say it's the study of life on earth! If you break the word ecology down, ' eco ' means house and ' logos ' means to study. So, essentially we are studying about our house in the biggest sense, which is Planet Earth! When scientists study the ecology of certain areas, they call those areas ecosystems.

Exciting, right? Ecology has not yet explicitly developed the kind of cohesive, simplifying generalizations exemplified by, say, the laws of physics. Nevertheless there are a number of generalizations that are already evident in what we now know about the ecosphere and that can be organized into a kind of informal set of laws of ecology. It reflects the existence of the elaborate network of interconnections in the ecosphere: among different living organisms, and between populations, species, and individual organisms and their physicochemical surroundings. The single fact that an ecosystem consists of multiple interconnected parts, which act on one another, has some surprising consequences. Our ability to picture the behavior of such systems has been helped considerably by the development, even more recent than ecology, of the science of cybernetics. We owe the basic concept, and the word itself, to the inventive mind of the late Norbert Wiener.

My first year there, I co-taught the course with my colleague Lin Jiang. I did what is probably fairly typical: I asked him for the materials he used when he last taught the course and then modified those. That involved deciding what the key concepts were that we wanted all students who had completed ecology to know. Coming up with that list was incredibly useful and changed the way I taught the next time. But I feel like I want to think more about the core concepts again. In my experience, most of these students have had no prior exposure to ecology. Something I am very interested in doing is better assessing what they know about ecology when they start the course.
