In 2012, the world’s population reached 7 billion with United Nations projecting an increase to 8 billion by the end of the decade. Population growth has required huge investment in urban development such as housing and infrastructure, often at the expense of natural systems. Coastal systems like lagoons have arguably been disturbed the most by human population pressures with 60% of humans living on the coast. In Australia, a greater proportion of people live in these areas with 85% of people living within 50km of the coast. Despite these high densities, there are no formal, global estimates of the amount of degradation coastal systems have experienced and regional baseline data is often lacking. The development of San Francisco Bay is said to be consistent with global trends with 79% of tidal marshes (including lagoons) being converted to human-dominated systems. When coastal systems are urbanised, habitat quality for biota declines as a result of loss and alteration of native vegetation, eutrophication and poor water quality. This decline changes community dynamics of both vertebrates and invertebrates as well as the community health and biodiversity.
My research aims to investigate the impacts of urbanisation on insectivorous bat community dynamics.
