Salinity Species like fish and prawns migrate and thus avoid stressful salinities when conditions are unfavourable The less mobile organisms such as Cyclograpsus punctatus can’t tolerate salinities below 20% migrating into certain suitable sections of the estuary. Sesarma catenata moves further into the estuaries as it tolerates 7% but S. eulimene occur near the head of the estuaries where salinities reaches 2. 7% Floods influences the salinity levels and result in very low salinity which

The country of Panama is roughly 18 million acres in size; deforestation cuts down approximately the area of Panama in trees and other plant life every year (United Nations FAO n.pag.). This ruination of the world’s greatest resource is startling. The globe is heavily dependent on the valuable raw materials produced from the forests, yet as supplies dwindle, humanity continues along this devastating path. The economic and human welfare boost and expansion of both farmland and living space that

Ecology | | | | Ecology addresses the full scale of life, from tiny bacteria to processes that span the entire planet. Ecologists study many diverse andcomplex relations among species, such aspredation and pollination. The diversity of life is organized into different habitats, from terrestrial(middle) to aquatic ecosystems. | Ecology (from Greek: οἶκος

A keystone species is a species that fulfills a very important role in its habitat. When a keystone species is eradicated from the habitat, that habitat undergoes extreme changes. The loss of a keystone species can cause other species to leave the environment and create a domino effect of outcomes. The loss of any organism in a habitat messes up the systems and relationships between other creatures and the balance of the habitat suffers. Many keystone species are predators who are essential to their

Module 3 Waves and the Electromagnetic Spectrum Topic: Waves 1. What is a wave? A wave is vibration that travels and all waves are created by something vibrating. Waves transport energy but do not transport mass. 2. Describe the following terms associated with waves: a. amplitude height of wave b. wavelength length of a wave c. frequency number of waves per second (Hz) d. period how long a wave lasts when it arrives at a fixed point (measured in seconds) 3. What are radio waves

available in the limestone forests, as well as provide data for researchers to pursue further studies as to why species are so limited here on this island. Introduction Tropical rainforests, along with temperate ones, are the most complex biomes on earth. This is due to the many ecosystems found within them. Although it is assumed that rainforest are fertile with plant species due to nutrient-rich soil, it is not. Most nutrients are either washed away from the soil due to heavy rainfall or

The Lion King Essay When is a movie not just a movie? When it has been painstakingly researched, as in the case of Disney’s The Lion King. It took Disney three years to make The Lion King, and a significant portion of that time was spent researching Africa and its ecology to make sure they portrayed everything correctly. The Lion King is an entertaining movie, but it also has ecological lessons for the discerning viewer. For instance, a large food chain, or multiple series of organisms each dependent

Deforestation Deforestation causes extinction in certain species. Humans are a species and we depend on other species for our survival. Land use directly leads to species extinction (Turk, J & Bensel T 2011 chapter 4). Humans should reserve biomes and aquatic zones because life is dependent upon it. An interruption to these zones causes a depleting effect creating irreversible lose of important organisms. Extinction is a natural selection process
