However, the long-term effects of transportation infrastructure are not well understood; these include land-use changes, changes in landscape patterns, and the alteration of ecosystem services.
Argentine ants displace native ants and other arthropod fauna [ 52, 53], disrupting important plant-ant interactions [ 54] and leading to the alteration of ecosystem functioning and cascading effects on other trophic levels [ 55].
In areas where urbanization is not controlled, the concentration of human presence in residential and industrial settings may lead to an alteration of ecosystems patterns and processes.
Human alteration of ecosystems prior to Euro-American contact in the area that became the conterminous United States disproportionately affected terrestrial systems compared to freshwater ecosystems, primarily through the use of fire and agriculture in some regions of the United States.
The human mediated transfer of harmful organisms via shipping, specifically via ballast water transport, leading to the loss of biodiversity, alteration of ecosystems, negative impacts on human health and in some regions economic loss, has raised considerable attention especially in the last decade.
Crop yields have been damaged, and the impact of an increase in extreme events has resulted in "alteration of ecosystems, disruption of food production and water supply, damage to infrastructure and settlements, increases in morbidity and mortality, and consequences for mental health and human well-being".
Alterations of ecosystems and natural resources contribute to the emergence and spread of infectious disease agents.
The change detection results identify hot-spots of forest fragmentation where mitigation measures should be taken, so that further irreversible alteration of the ecosystem is prevented.
Therefore, cost efficient approaches that introduce minimal alteration of the ecosystem are desirable.
Fungal pathogens have a broad spectrum of hosts, including plants and animals, and may cause death and disability in humans, yield loss in agricultural crops and even alteration of forest ecosystem dynamics.
Further, rapid ecological changes associated with anthropogenic alteration of natural ecosystems can promote contemporary evolution, with unanticipated consequences.
