The Spillway or City Park: Which has more arthropod diversity? Author: Madeline Lafargue BIOS1071-007 Group Members: Rebecca Ostrowski and Khayla Wright ABSTRACT The purpose of this study is to find out how habitat type affects arthropod diversity. There are many different types of arthropods, making up the majority of animal life on Earth. Arthropods vary among different climates and conditions, including some near water habitats and some habitats without water. The following…

animals. This paper aims to outline a single form of invasive species giving full account of its origin and other specifics. Furthermore, it outlines the factors that have led to the successful existence of the species in a strange or non-native ecosystem. In this paper, the case will be the Wild Boar. The wild boar is native to Eurasia. The main reason for its import was to provide alternative food source and it is said that the Wild boar escaped domestication. Nonetheless, other scientists…

integral components of many golf courses that serve a number of important functions; they provide water for irrigation, mitigate flooding by holding stormwater and can serve as important design features. Water features are rich, complex, living ecosystems that provide habitat for plants, animals and microorganisms. Water features evolve over time and most require some level of management to remain in good condition. The maintenance practices used to manage a water feature depend on its age, size…

With little knowledge of the potential threat to foreign ecosystems, a cargo ship could travel from one region of the world to another, bringing with it any and all alien species aboard, whether intentional or not. It is most commonly thought that the first zebra mussel species was brought to North America in the…

relationship an organism has with other organisms and the relationship the organism has with their surrounding environment (Ecology, 2015). The creeks were a perfect example of an ecosystem in our study because they had different Abiotic and Biotic factors that we could look at to support our hypothesis and prediction. An ecosystem is an environment where abiotic (nonliving) and biotic (living) interact with each other(Brooker,Widmaier,Graham,Stiling, 2011). The purpose of this experiment was so…

“Invasive species” refers to an ‘alien species’ whose introduction ‘does or is likely to cause economic or environmental harm, or harm to human health.’ Although this is a species that is not native to a particular ecosystem, it is important to realise that not all non-native species are invasive. A ‘native’ species is one which is found within a particular region. An invasive species has the potential to influence a wide range of areas, including; environmental, economic and social factors.…

Invasive species Invasive species are one of the largest threats to our ecosystems, weakening them and creating a growing pressure on agriculture and plant life. Invasive species, or ‘alien’ non native species compete or predate on native plants that have not been able to develop adaptations to cope with them. One of the most dangerous invasive species is the Asian Longhorned Beetle, which infests a variety of hardwood trees in North America and Northeastern Asia. The Asian Longhorned Beetle…

The author’s hypothesis: -The author’s objectives/hypothesis were to see how trade-offs between ecosystem services above and below grounds effect biodiversity and how they are important. They also want to understand the effects of succession and believed the best way to do so was to look at a range of different ecosystem processes and services. The services they are looking at are things like C-pools (Carbon- pools) and fluxes and soil nutrient dynamics.…

RICHNESS: is the total number of different species in the area • RELATIVE ABANDANCE: is the proportion each species represents in that certain measured area. we recognize three types of biodiversity 1.genetic diversity 2.species diversity and 3.ecosystem diversity ( COUNTRY LIFE ,April 2011.) Species diversity means a measurement of species richness and evenness as well as the variety of organisms…

Assignment 1: Biodiversity Issue – Tanya Williams Feral Horses: a cultural icon or an environmental nightmare. With the population of brumbies growing, the Victorian government are looking to find alternative ways to manage the numbers of feral horses that are living within the Alpine environment. However, when Australians think about wild horses, they associate them with the Australian identity as they have helped form our ‘outback’ culture. This has caused debate between environmentalists…
