Yet, practical problems arise where the effects of man-made alterations in the hydrological environment on ecological communities need to be known.
This is particularly important as man-made alterations to flow regime affect flows into wetlands, and therefore sea-level rise impacts on heavily developed coastal areas of the world, like eastern Australia40, eastern US41, eastern China47 and Western Europe48.
In most cases, the cause or causes are unknown, but are assumed to result from man-made alterations in the environment.
Roads are among the most recent of man-made habitat alterations, having spread dramatically during the past century following the development of motor vehicles (Huston 2005).
Despite the seemingly well-functioning adaptation of wolves to man-made habitat alterations, we should be aware that roads may interact with human attitudes, enabling increased human-caused mortality of wolves.
This study focuses on historical patterns and processes, but the inferences can contribute to the improvement of conservation measures in the future, as the species confront both natural and man-made ecosystem alterations.
There are other success stories of species that have adaptively responded to man-made habitat alterations while still avoiding increased rates of human-caused mortality, for example urban wildlife or raptors feeding on vehicle-killed prey (Tuomainen and Candolin 2011; Francis and Chadwick 2012).
"We live in an era of man-made climate change.
The man-made or man-induced alteration of the chemical, physical, biological, and radiological integrity of water.
In addition, several man-made hybrids have been made.
In addition, glass wool, which represents a man-made mineral fiber and a substitute for asbestos, did not cause such an alteration in expression of activating receptors, unlike CB asbestos.
