Bio 1 River Ecology Lab Report Ecology is the study of relationships between organisms and their environment which includes both physical and biological factors. Humans have a major influence on ecosystems and this is very important in the waterways of California. The American River has been influenced greatly by humans by mining for gold‚ pollution through humans themselves‚ and an immense amount of other things (Becker 1992). We tested the growth of bacteria in the water of the American

Succession‚ the process of a community changing over time‚ can be broken down into sub groups such as ecological‚ primary‚ pond‚ and secondary. Ecological succession being the most basic. In the Succession Lab‚ we observed a community in a ecosystem. As we recorded the data each class‚ we observed that succession takes place with rapid speed for in each observation‚ a new specimen is identified. A niche is how the organisms live‚ what their role in the community is. For example‚ an ecological

Parking Lot Biodiversity Background: Species diversity can be measured & described in many different ways. Species evenness describes how evenly distributed all the species are in a community while species richness describes how many different types of species there are in a community. Diversity Indices are one method used to measure species diversity in nature‚ and determine the degree of species evenness and species richness in an area. Using these calculations‚ ecologists can al

BIOL 1121: General Biology II Lab Fall 2014 Abstract Mark and recapture is a method commonly used in ecology to estimate an animal population ’s size. A portion of the population is captured‚ marked‚ and released. This lab provides methods that can be used to estimate a provided additional information for a better interpretation of lichen diversity values in biomonitoring studies of air pollution.

The UN Earth Summit in Rio de Janeiro in 1992 defined biodiversity as being the variability between all living organisms‚ terrestrial‚ marine and aquatic. This includes the diversity within species‚ between species and of ecosystems. A reasonable standard of living does not mean that a person should live at a luxury level‚ but neither does it mean that a person should only live at a subsistence level. It should be somewhere in between where the person can afford to eat nutritious food‚ buy clothes

The purpose of this lab is to observe the relationship between predator and prey populations as well as to observe the effects of competition in regards to space/habitat and food supply. It is also to observe some of the major factors that contribute to population increases and decreases and to learn how to plot data to observe patterns. I can determine the relationship between the predator and prey by analyzing the correlation between the two. I believe that the results will show that the predator
