The following graph depicts the relationship between Lynx and Hare populations. During this module, you will look at specific examples of these relationships. When one species has even the slightest advantage over another, the one with the advantage will dominate in the long term. Gas analysis is used to extract information from tiny bubbles containing atmospheric gas that becomes trapped in the ice cores. This includes Aboriginal rock paintings, rock structure and formation, and ice core drilling. The existence of mid-ocean ridges provides evidence that continents were once joined together.

Radiometric dating can be used to determine the absolute age of a material such as rocks or fossils. This module will expand on relationships between biotic and abiotic factors in an ecosystem. In 1993, a change in ecosystem dynamics caused a disease outbreak in a human population. Video footage of this animal is rare and a short clip of the last animal in captivity was recently rediscovered. Recognizing the value of a long-term perspective on how ecosystems change over time, GLERL has invested in researching the southern basin of Lake Michigan since the 1970s. This increase in predators decreases the hare population, to the point that Lynx run out of food and decline. by Alex Gao. A simple example is a food web that shows how change to one species leads to flow-on effects for other species as a result. You can find the answers at the bottom of the page. Ecosystem Dynamics. Our focus will be the relationship between the endangered Spotted Tailed Quoll and introduced Red Fox.

Estuaries are dynamic ecosystems that host some of the highest biodiversity and biological production in the world (Bianchi, 2007).At the land–ocean interface, estuaries receive large amounts of dissolved and particulate carbon (C), nitrogen (N), phosphorus (P), and silica from rivers. Environment Everything that surrounds an organism and influences it. The biodiversity of the Earth has constantly changed since life first appeared on the planet. The Theory of Evolution by Natural Selection can be used to explain periodic increases and decreases in populations and biodiversity. Commensalism is the relationship between two organisms where one organism benefits while the other is unaffected. (b) Explain the pattern of abundance seen in the Lynx and the Hare populations. In order for you to see this page as it is meant to appear, we ask that you please re-enable your Javascript! (a) When a large number of individuals of a species are killed. Therefore, this leads to a decrease in the Hare population which would ultimately decrease the Lynx population as well. Australian Sclerophyll plants, Eucalyptus, Banksia and Acacia. The Sin Nombre Virus: Ecosystem Dynamics in a Human Population. Module 4 allows us to apply basic knowledge of biology with studies of evolutionary biology and biodiversity to analyse how ecosystems have changed and will change over the course of history. The key postulates that have guided science since the Enlightenment appear to be wholly inadequate to describe properly the development of ecosystems. These are the ‘services’ a functioning ecosystem provides. The interaction between the Lynx and the Hare shows that predation affects the population of both prey and the predator.

Planting local trees to restore vegetation. The distribution of fossils also supports the idea of continental drift, as fossils of some organisms are found on continents that now are very far apart and have different habitats. Oops! (d) A sudden decrease in biodiversity on Earth. Scientific knowledge gained from the fossil record and geological evidence enables scientists to study the complex relationships between biotic and abiotic factors. This eventually results in an increase in lynx and the cycle starts again. This includes: An example of such a restoration practice includes the Westside Mine in Lake Macquarie, New South Wales that was successfully restored post-mining in 2012. Evidence of continental drift helps us understand how environments on different continents would have changed in the past. analyses ecosystem dynamics and the interrelationships of organisms within the ecosystem BIO11-11 Content Focus The Earth’s biodiversit y has increased since life first appeared on the planet. The modern-day prevalence of sclerophyll plants in Australia provides evidence that as Australia drifted North from Antarctica, its climate became warmer and drier.
