Science: Species extinctions and shrinking scope have led to the collapse of the global food web

More than half of the food web links of terrestrial mammals have disappeared due to extinction and shrinking range since the Late Pleistocene, according to a new study that used deep learning models to identify changes in

Human activities have led to the extinction and demise of contemporary species and have a knock-on effect on global biodiversity and ecosystem functions by destroying food webs

However, the impact of these declines on the food web is difficult to understand, as species-specific predator-prey interactions are rarely preserved

What's more, while much of the decline in the global food web stems from species extinctions that occurred long ago, the shrinking range of extant mammals has led to a similar decline, suggesting that the restoration of biological natural ranges can fundamentally restore the complexity
