The catastrophic decline around the world of “apex” predators such as wolves, cougars, lions or sharks has led to a huge increase in smaller “mesopredators” that are causing major economic and ecological disruptions, a new study concludes.
The findings, published today in the journal Bioscience, found that in North America all of the largest terrestrial predators have been in decline during the past 200 years while the ranges of 60 percent of mesopredators have expanded. The problem is global, growing and severe, scientists say, with few solutions in sight.
An example: in parts of Sub-Saharan Africa, lion and leopard populations have been decimated, allowing a surge in the “mesopredator” population next down the line, baboons. In some cases children are now being kept home from school to guard family gardens from brazen packs of crop-raiding baboons. (…)
Primary or apex predators can actually benefit prey populations by suppressing smaller predators, and failure to consider this mechanism has triggered collapses of entire ecosystems.
