Numbinbah Valley Analysis

The macroinvertebrates graph (figure 2) represents the diversity of species inhabiting the Baldwin Swamp. In 2009 the Baldwin swamp was flourishing with a large diversity of species. A total of 33 macroinvertebrates, 8 species were recorded. At this time the baldwin swamp was healthy, abundant in life and the ecosystem and food webs were unaffected by the floods. Whereas 3 weeks after the floods swept through there were little to no range of species of macroinvertebrates. There were a recorded amount of 2 Damselfly Nymph and 1 waterboat man. A theory to why these two

One of those relationships, food webs, has an important function of transferring energy and keeping the biological lifecycle going by the various lifeforms feeding off one another. The concept of energy transfer that goes on in food chains in ecosystems keeps organisms living by the energy the body needs being provided when they eat other organisms, as supported by the studies of “food chains, food webs, and trophic levels.” It is important that we continue to observe ecosystems like the Everglades Hardwood Hammock in order to help preserve them.

Ecology is how organisms interact with each other and the environment. The Lion King is linked to ecology by showing how organisms interact with each other and the environment. My three topics are how symbiotic relationships are important to a community, how limiting factors affect a community, how communities respond to abiotic or biotic factors, and how this is linked to the movie and Ecology. Symbiotic Relationships are interactions between two species and how they affect each other. There are three different types of symbiotic relationships Mutualism, Commensalism, and Parasitism.

Although it supports a number of different organisms, Nudgee Beach lacks many of the fundamentals that make up a healthy and successful ecosystem. The first indicator of this is from the lack of birds present in the area. Although it has been noted for terrestrial bird species – such as kingfishers, pelicans, ibis, egrets, jabiru, stilts and heron – and wading bird species – such as golden plovers, curlews, tattlers and godwits – to have been spotted at Nudgee Beach and surrounding areas in the past; after a day’s worth of extensive observation and research, it was found that the birds observed were limited to magpie, ibis, great knot and eastern curlew species. To intensify this factor, at the time by which this lack of species was recorded, Nudgee Beach was expected to have started seeing tens of thousands of birds arrive for the migratory season [21]. This blatant lack of bird species diversity and quantity may have been due to the lack of small organisms within the ecosystem. The restricted number of small organisms at Nudgee Beach is detrimental to the entire ecosystem as these organisms make up the bottom levels of the food web and provide higher-level organisms with adequate amounts of food to consume. The smaller organisms expected to be observed – including; crustacean, shell, mollusc, lizard, frog, fish, worm, arachnid and insect species – was limited to the infrequent observation of crustacean, shell,

It is understood that there is not just one problem causing the dead zone in the bay. Two main contributors are the focus. Details are presented on the problems brought to the bay by agriculture, and development. The language is easy to understand and the scientific and environmental message is conveyed in a way that can be followed.

The aim of our excursion to Hastings Point, New South Wales was to study the biodiversity and ecology and to see how these organisms behave in their natural habitat and surroundings. There will also be information collected about a variety of different organisms as well as population counts and observe how they have adapted to the species surrounding environment. The excursion will also be an opportunity to gather information on

With this type of substratum, it favours idyllic conditions for various types of vegetation to inhabit and create the optimum conditions for roach due to them being both herbivorous and detritivorous feeders (Weatherley, 1987; Brabrand, 1985). Looking at figure 8 this is demonstrated as the Trews weir shows that roach have the fastest growth rate and also attain the largest size than any other site with they are found. From looking at Figure 9 and 10 it is evident that roach find this type of area far more beneficial then dace as roach are in higher abundances at this site. According to a study that had previously taken place by Cowx, 1989 said that dace and roach sampled from the Trews Weir had a significant dietary over lap in this area; figures 9 and 10 also show this.

Primary producers produce their own nutrients, and make their own food through photosynthesis. Those organisms are plankton and sea weeds. The second on trophic levels are the secondary consumers such as smaller fish and sea urchins. Third on the trophic levels are decomposers. Decomposers are lobsters and sea turtles. Tertiary consumers are the top of the food chain, they are sharks and bigger fish. Predation is major in a coral reef because there is so much food supply. Mimicry is used to keep the predators away but wearing bright

Similarly, the Melbourne wrap has been active (Gill, 1961) leading to different faults that have decided deposition and landscape formation in the south Gippsland region of eastern Victoria (Jenkin, 1976b).

Girrahween Park is situated on The Walk and features a large recreational area along Wolli Creek's northern bank. You get stunning views of Bardwell Park, Arncliffe, and Turrella from this park. This park is heritage listed and is part of the rare remnant of bushlands in the region. There is a hiking trail, picnic area, barbeque area, outdoor rock climbing facilities, and a lot of beautiful plant life and some native birds to watch. The locals consider this park to be its hidden oasis in the suburb.

The catchment lies at the north of the Illawarra Plateau, which stretches from Heathcote National

Our sites (Figure 1.) were spread along the lowest reach of Merri Creek before it runs into the Yarra River. As a direct result of this there is an extensive valley from the constant presence of fluvial processes over geological time. The landform patterns at our sites were extensively governed by the movement and availability of water, with escarpments, gullies, cliffs and spurs of varying steepness all observed.

During the reign of the third riech the Nazi party committed many atrocities. Today the main ones focused on in school curriculum are the concentration camps and the ghettos. But during the war in Russia the Germans faced a logistical nightmare of moving the Russian Jews to the camps back in Prussia or Germany. The solution to this was the Babi Yar ravine.

The diversity, and population of macroinvertbrates will be lower in Enoggera Creek than Cedar Creek. As gradient profiles with high steepness result in high water flow rate, and riffle zones that produce variables that are typically within in the tolerance range of more invertebrates (eg. high dissolved oxygen, temperature, and low turbidity) and allow the transport of food particles. While due to the shallower gradient of Enoggera Creek, it can be assumed that there is a lower water flow rate. This results in a comparatively lower dissolved oxygen level, higher temperature, higher tubidity (especially in terms of pollution), and possibly less food sources (due to less species colonisation in these areas) - which is optimal for fewer species

Ecology today can be defined as “the study of the interrelationships between living things and their environment”. It is important to understand that when we say that ecology includes the “environment”, we are talking about everything that is external to an organism, all the biotic and abiotic. Nowadays it also attempts to understand and explain the how and why of the origins and mechanisms of interactions.
