The scientists conclude: We propose that many of the ecological surprises that have confronted society over the past centuriespandemics, population collapses of species we value and eruptions of those we do not, major shifts in ecosystem states, and losses of diverse ecosystem serviceswere caused or facilitated by altered top-down forcing regimes associated with the loss of native apex consumers or the introduction of exotics. What would happen if squirrels went extinct? Theres one more possible future left, the most hopeful one. First, she says, the axolotl is a poster child for all the species with miraculous, useful adaptations that we dont find before its too late. When a predatory species becomes threatened or extinct, this removes a check and balance in the food chain on the population of prey previously consumed by that predator.

Or if the main species of bird to benefit was the destructive starling? What Would Happen If Snakes Went Extinct? There are 50-plus species of seahorses.
