Ecological succession

At his inauguration as 45th president of the United States on 20 January 2017, Donald Trump said "From this day forward, it's going to be only America first -- America first. . . Protection will lead to great prosperity and strength. . . We will follow two simple rules -- buy American and hire American." Clearly, the United States and the world have entered an uncharted territory. He has three clear and chilling messages: From now on, America will be self-centered, protectionist, and less…

During this lab, we finish watching the video “earth from space” and begin discussing the procedures that will be taking place at the COM field ecology laboratory. We learn about the experiments that will be conduct to study primary production, ecological succession and population dynamics in the lab. Discussion A. What is primary production? Primary production is the production of biomass from chemical energy (primarily sunlight) “during a given time of period in an ecosystem” (pg. 1235) it…

Ecological succession is predictable changes over time. Ecological succession changes the environment because the environment might have to almost start from scratch again or everything in the ecosystem can be completely turned upside down, but through succession, the ecosystem can be brought back to its former glory. We see examples of this in the movie, one example is the fire at…

of the first ecologist to study the eruption. She expected to find complete devastation but was shocked to find pockets of life on the mountain. The mountain did not follow traditional succession models. Virginia determined that the climate and weather played an important role in this non-traditional succession. In the last couple of decades over 150 different plant species and several animal species have returned to the affected area. This had…

The Effects of Acid Rain in the Temperate Deciduous Forest The temperate deciduous forest has many environmental threats, such as deforestation, introduction of non-native species, overgrazing, and much more. One prominent issue, other than the cutting down of trees, is the constant occurrence of acid rain and pollutants in the air. Acid rain is essentially rainfall made acidic due to atmospheric pollution that causes environmental harm, typically to forests and lakes. The main cause of this…

organic. Mechanical is a more primitive form of society and organic is a more modern form. Durkheim focused more on the influence of social backgrounds that have an effect on human behavior. There are three subtypes of social structure theories: ecological/environmental, strain, and cultural deviance. One of Durkheim’s argument was that…

and that species inherently transform and mutate over long periods of time. Darwin argues that species have mechanisms and methods that modify them over long periods of time to increase chances of survival and reproduction. Darwin argues that ecological and climate factors drive species to adapt, change, and morph to be better suited to survive and excel within their niche. Throughout these chapters Darwin constantly is…

“START!” my science teacher yelled. I lunged for the beans with my chopsticks. Grabbing one, I placed it in my bowl and immediately went for another. Struggling with my 6th bean, I looked at my friend effortlessly depositing beans into her bowl with tweezers as the timer ran out. How could this be? Unwilling to disprove my hypothesis, I tried again with tweezers. Ten, Eleven, Twelve?! I loved the unexpected results of an experiment and there was always so much more to learn. Since that…
