Chapter 46 Ecology Of Populations

The article discussed the changes in many habitats due to anthropogenic activity. Anthropogenic is an adjective that describes changes in nature due to the people. Next, this article discussed climate change and the impact that it is having on species like clams, and fish due to ocean temperatures rising. The article also addressed carbon dating of fossils to look for cause of extinctions. Human development and agriculture have had a tremendous impact on the population of many species that are terrestrial. Deforestation is a big problem that has caused a decline in the bird species. Commercial fishing in many areas has led to a decline in fish populations. Furthermore this article

A. Responsiveness – organisms respond to changes in their immediate environment (long term changes is adaptability)

The environment determines which traits are most evolutionary desirable to an organism. If a population should move or should the environment change, a different set of traits would be the most advantageous

A biotic factor is anything that is classified as a living organism, and also makes up an ecosystem. These biotic factors also affect the other organisms in their ecosystem. In an ecosystem there are three types of parts to a biotic compound that make up a food chain and they are as follows. Producers, which convert natural energy into a food source for consumers. Then, there are consumers who

Aristotle, the last of the great Greek philosophers, circa 384-322 B.C. and the first of Europe’s great biologists , who studied at Plato’s academy. He believed that everything in the natural world can be categorized into nonliving things with no potential for change, and living

As a set of interacting species found in the same place and functioning together, this enabling life to persist. That is essentially the definition we used earlier. A problem with this term and definition is that it is often difficult in practice to know the entire set of interacting species. A resource, in ecological terms, is something such as food, water, habitat, and sunlight, prey that is required by an organism to perform a vital function such as grow or reproduce. A consumer is an organism that consumes a resource such as predators and herbivores (Botkin, 2015). Ecosystems are collections of plants, animals, and micro-organisms interacting among themselves and with their habitat. While most ecosystems are hard to define and draw rigid boundaries around, scientists characterize them by their rock and soil types, by water features such as streams and ponds, and by the common plant and animal species which make their homes within these areas. This, most interactions between animals involve one or more competitor species competing for a resource. Ecosystem management also recognizes the influence of natural disturbances such as fire and windstorms, accepting that natural ecosystems are dynamic and change over time. Biological production is the capture of usable energy from the environment to produce

Alfred Russel Wallace, the father of zoogeography, was very influential to the field of biogeography. Born in 1823, he spent his life studying the connections between geographic variation between species and the physical features of Earth. Wallace noted the significance between geography and the creation of new species. For example, a species is separated into two groups on opposite side of a mountain range that forms. Over time, both populations evolve so much to their specific habitat that the groups are so dissimilar that they are two different species.

These are just a few of the numerous amount of great scientists who contributed to one of the many different fields of biology. Even though he’s not often associated with biology, Aristotle played an important role in the classification of organisms. He was the first person credited with differentiating between different organisms; he started noticing differences between plants and animals like the existence of blood in animals and the lack of blood in plants. Charles Darwin had a great impact on the world of biology. His theory of evolution is still used for studying evolution today. Robert Hooke’s biggest impact in biology concerns the field of microbiology. Hooke is credited with the discovery and naming of cells, which he discovered while looking at a microscopic image of a piece of cork. Gregor Mendel is one of the most famous names in the field of genetics. In fact, his discoveries paved the way for much of today’s modern genetics. While studying the habits of pure pea plants Mendel discovered the pathways of dominant and recessive

I think that both environmental and genetic factors influence traits of living organisms. Both hereditary and environmental effects influence organisms and the way they look and act. Traits affected by genetic or environmental factors include sexual orientation, twins (the way they look and act), physical appearance, IQ, and mental illnesses.

Urie Broonfenbrenner has five ecological-systems (renamed it to bioecological theory) approach which are microsystems, exosystems, macrosystems, chronosystem and mesosystem. Microsystems is Berger (2014) each person’s immediate surroundings, such as family and peer group. Exosystems is Berger (2014) local institutions such as school and church. Macrosystems is Berger (2014) the larger social setting, including cultural values, economic policies, and political processes. Chronosystem is Berger (2014) literally, “time system.” Mesosystem is Berger (2014) consisting of the connections among the other systems. Some examples of Microsystems would be my classroom Psychology 200 (online), Exosystems would be my place of employment which would FWPS

An ecosystem is “A biological community of interacting organisms and their physical environment.” As stated by Oxford Dictionary, 2017. An ecosystem can range in size from a tiny pond to, the entire world, by its definition. Ecosystems contain all of the complex relationships that occur between living things and their surroundings, including other living things (biotic factors) and non-living external factors (abiotic factors). The aim of this report is to investigate the effects of human activity on an ecosystem, I have chosen to base this report on the ecosystems that are generally seen in a desert biome. [98 words]

*__Behaviors of organisms__ - such as feeding territories, or migration. Migrating allows birds to live in more optimal conditions year round, with plenty of food resources. Feeding territories allow wolf packs or mountain lions enough space to range for

Ecological Social Theory was developed from Urie Bronfenbrenner. Bronfenbrenner wanted to show how a person’s development is based off of influences of several

Erika, as I record your discussion you made serious points on species going extinct and the de extinction procedure. Species plays a significant function in humans live and in the natural surroundings. Erika we as humans eat food and it keeps us active. Do you think species will be the same or have the same nutrients? As we know in our environment today chemicals are used to make species grow faster. It makes me question and wonder how scientists are taking our environment into their own hands. There should special laws on how and what species are to be recreated. I personally feel species should be left alone and let our creator continue to replenish our

Charles Darwin originally had an idea of which animals in a changing environment will change with it. That is
