"Historical perspectives have been an integral component of ecological studies as shown by palaeontological research, historical ecology, genetic, isotopic and other approaches to the reconstruction of past species distributions and community structure as well as the evolution of flora and fauna through time. With the exponential growth of the worldâs human population over the past century, 60% of humans living within 100 km of the coast, and the projected consequences of current climate change, pollution, habitat loss and introduction of alien species, coastal environments appear to face particularly serious challenges when compared to other ecosystems. The need of forecasting the combined effects of all these physical and biological variables with some accuracy is ever more pressing if we are to mitigate and manage such changes effectively.

It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
