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

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

Food chains‚ Food Webs and the Flow of Energy in Ecosystems Introduction An ecosystem can be defined as a more or less self-contained function unit in ecology consisting of all abiotic and biotic interactions in a specific area. Flow of energy within an ecosystem is a one-way process; Photosynthesis utilizes light (solar) energy to yield chemical energy that is passed on to organisms at significantly reduced amounts at each level of nutrition. This ‘inefficiency’ in energy transfer is the principal constrain

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

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

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

Freshwater Ecosystem Richard Parker SCIE131-Q4WW-F14 Professor Susann Brown 10/5/14 Freshwater Ecosystem An ecosystem is an environment filled with living plants‚ organisms‚ and animals. There are for main components in an ecosystem. The relationship of these four components makes it possible for each component to pass energy and use the food chain to survive and flourish. Elements and compounds are basically a required food source for plants. Plants utilize the sun and photosynthesis to harness

The Rocky Mountains A look into the alpine biome’s ecosystems and a potential stressor to them The Rocky Mountains are located in the biome known as the alpine forest. The Rocky Mountains are a large mountain range that is located in western North America which runs more than 3‚000 miles‚ from the northernmost part of British Columbia‚ in western Canada‚ to New Mexico‚ in the southwestern United States. Average January temperatures in the Rocky Mountains can range from -20 °F to 43 °F‚ with
