Abstract Global change means the complex of environmental changes which occurs on the glob due to the inappropriate use of natural resources. Ecological disturbances affect the emergence and spreading of vector born infectious diseases, such as Leishmaniasis , malaria giardisis, tripanosomiasis, schistosomiasis and onchocerciasis. Every environmental change as a result of the improper utilization of natural resources or due to the occurrence of a natural phenomena, leads to the disturbances of the ecological balance and ways of vectors and parasites multiply, grow and transmit a disease. Each species occupies a specific ecological niche, so vector species sub-populations have a similar behavior and genetics as they adapt to man-made environments. In adapting to a changed environmental condition, including the settlement of human affecting and reducing other living things, some vectors change from primary zoophilllic to primary anthrophillic.Clearing of …show more content…

    In Urban area many animals are adapting to walking/running on concrete. This means that in the event that world destruction was to occur and these animals were forced to run and catch food on their own in the wild it will be a great struggle for them.

When Plagues strike people and animals alike die horrifically, in turn fleas need to find other sources of food. The people living in poor conditions often get forayed by flea bites, thus infecting them (“Ecology and Transmission“). It was seldom for the Black Death to be spread from person to person.

In forensic science, DNA testing is used to compare the genetic structure of two individuals to establish whether there is a genetic relationship between them. One example of the use of DNA in forensic science that is important in biology today is comparing a suspect’s DNA profile to DNA that was discovered at a crime scene.

  • Literature Review On Eutrophication

    754 Words  | 4 Pages

    It is well known that eutrophication occurs when excess nutrients are added to a body of water and primary productivity is increased. However, the scientific paper, Aquatic eutrophication promotes pathogenic infection in amphibians, puts a direct focus on a specific parasite, Ribeiroia ondatra, and seeks to give evidence that the onset of eutrophication is the driving factor allowing the parasite to disrupt amphibian development. The authors set-out with the goal to provide evidence that eutrophication leads to an increase in the number of snails as intermediate hosts for the parasite, while also increasing the snail size and reducing snail mortality; providing more candidates to pass the parasite onto amphibians to inhibit their development. This research, as stated in the paper, looks to identify eutrophication as the factor promoting this pathogenic infection in the amphibians. Although some have tried to pinpoint this already, no evidence prior had been provided to
