Investigating the Control Dynamics of an Algae-Brine Shrimp Ecosystem 113437768 Introduction The purpose of this lab is to investigate whether an ecosystem consisting of marine algae and brine shrimp are controlled by top-down or bottom-up mechanisms. The terms top-down and bottom-up in the context of ecology describe which trophic levels are enforcing population pressures on the others. Thus‚ the top-down mechanism of control holds that consumers are responsible for determining the abundance of

Science course work Aim- To see how the wavelength of visible light affects the rate of growth of aquatic plants Different wavelengths of light will effect to rate of photosynthesis. I will test this by exposing the pondweed to different wavelengths of light to see how it reacts. Method I will do this by passing white light through a filter. The filter will remove all unwanted wavelengths of light leaving the plant exposed to only the desired wavelength of light. I will use three different

sharks have an effect on marine ecosystems? In this report‚ I will explain how the overfishing of sharks has an effect on marine ecosystems. Also‚ I will be touching on the dangers to sharks worldwide and the catastrophic impacts that the mass depopulation of sharks could have on both animals and humans. Overall‚ sharks worldwide are in danger due to the fact that as many as 100 million sharks are killed each year. This has devastating effects on marine ecosystems due to the fact that sharks help

ABSTRACT Ecosystem service is a new term in the context of our country. The concept of payment to environmental services is a broad umbrella for the conservation of watershed. Watershed is the important part in the livelihood of people. With the watershed people survive and help it thrive. People here are the makers as well as destroyers. Within the watershed there are upstream dwellers that mainly provide the service to the dwellers living downstream. Hence this project is for the conservation

Charles Kay’s article‚ “Aboriginal Overkill and Native Burning: Implications for Modern Ecosystem Management‚” describes the apparent flaws in western environmental policy for park management. He describes how the current park management strategy is based on false interpretations of the perceived pre-Columbian‚ North American wilderness conditions and a desire to return to those conditions. Kay uses three major premises (intermediate conclusions) to support his argument against park policy and counter

PRACTICAL 3 ECOLOGICAL PATTERNS AND PROCESSES IN MANGROVE ECOSYSTEMS II PROBLEM SET 1. BIOLOGICAL INTERACTION During our Field Trip to the Cairns Airport Mangrove Boardwalk on 7th August‚ 2013‚ I observed a distinct distribution pattern in the locations of the Orange-Clawed Fiddler Crabs (Uca coarctata). Upon further investigation‚ I noticed that the larger males of the species (easily identifiable as those with one large claw) colonised the open areas located beside the Middle Creek viewing

How does the relationship between salt concentration effect osmosis in the aquatic plant Elodea? Quantitative data From observing the cells under a microscope‚ we see that they are continuously moving and therefore are alive. We have observed that when the cells are in the 10% sodium chloride‚ the chloroplasts are positioned to the sides of the cell wall and the cytoplasm is more expanded. Cells in the distilled water are slightly smaller than the cells in the sodium chloride solution and
