Abstract:
... Biodiversity loss and invasive species are exacting negative economic, environmental and societal impacts. While the monetary aspects of species invasion have been well-assessed, their impacts on human and social livelihood outcomes routinely remain obscure. Here, we empirically demonstrate several important human health and demographic consequences of a 1970s invasive pest species of cassava acro ...

Abstract:
... In rural Japan, various types of forest and grassland once used for agroforestry have now been abandoned because of socioeconomic changes associated with the decline in forestry, falling birth rate and aging population. The biodiversity of such secondary forests and grasslands, which had been maintained by routine management, is now in crisis. Among them, Kunugi (Quercus acutissima) forests in Kyu ...

Subject:
biodiversity; birth rate; carrying capacity; food availability; human population; humans; models; mortality; population growth; society
Abstract:
... The classic demographic transition model illustrates the pattern of birth and death rates over time, shifting from high and equivalent to low and equivalent, with population increasing sharply during this transition as a society industrialises. However, the model has a limited temporal frame and cultural scope. It also overlooks that human population trends follow agricultural productivity. Becaus ...

Abstract:
... Twenty‐five years ago, the snow leopard Uncia uncia, an endangered large cat, was eliminated from what is now Sagarmatha National Park (SNP). Heavy hunting pressure depleted that area of most medium–large mammals, before it became a park. After three decades of protection, the cessation of hunting and the recovery of wild ungulate populations, snow leopards have recently returned (four individuals ...
