or more different species that interact with one another in a defined space (Ricklefs 2008). By definition this is known as an ecological community. These interactions within the community is what accounts for many if not most ecosystem processes‚ including but certainly not limited to‚ food webs‚ nutrient cycling‚ and competition. As the interactions can greatly vary within different communities‚ it is difficult to define and measure (Harrison & Cornell 2008). The interactions themselves can be

detrimental to some species. The weakest and unhealthiest become dinner for those predators and also become a positive thing for the species that only the strongest of the herd will survive and continue to reproduce. Some types of prey have defense mechanisms which fight off predators. Survival of the fittest is the best explained phrase for this type of ecological interaction. Introduction Predator-prey relationships are a common interaction found in every type of ecosystems and communities

Many may not even appear to be invasive‚ as we’ve grown so accustomed to seeing them. The phrase “invasive species” is defined by the National Invasive Species Council as “. . .a species that is non-native to the ecosystem under consideration and whose introduction causes or is likely to cause economic or environmental harm or harm to human health” (University

Essay The Species At Risk Act (SARA) is a piece of legislation in Canada that exists in order to prevent the disappearance of species considered at risk as well as to facilitate the recovery of species that have been identified as being either incapable of subsisting in the wild‚ or a special concern as they are identified as having potential to become extinct or endangered in the future as a result of human activity. It is designed with the intention to protect the habitats of species as well as

Invasive Species have been described as an organism which is not native‚ and causes negative effects on the ecosystem‚ and to the health of humans. These organisms can be Fauna‚ Flora (Flora and Fauna refer to plant and wildlife‚ respectively)‚ a fungus or a bacterium. However‚ not all introduced species are invasive‚ but invasive Fauna and Flora‚ have been said to be the 2nd greatest threat to biodiversity post habitat loss. In his book‚ Invasive Species in a Changing World‚ Richard J. Hobbs (2013)

Rodent Interaction Lab Introduction In an experiment‚ adult female hamsters were exposed to both a conspecific male and a heterospecific male through wire-mesh barriers for 8 days‚ and then paired sequentially with the two males. It was found that female hamsters can learn during adulthood to avoid interspecific mating just by being exposed to stimuli from heterospecific males‚ (delBarco-Trillo et. al.‚ 2010). This experiment gives a lot of information on the behavior of hamsters in terms

Social interaction and touch initiation in public places ‘Touch’- is a fundamental behaviourism of non-verbal communication within the human species - it can be both powerful or subtle‚ and very complex. This observational study investigates the behaviour of non-verbal communication (NVC) in relation to touch initiation in public places. The group studied are of latter adolescent stage‚ and opposite sex couples. Henley started the first touching behaviour model – “and found a striking tendency for
