Fear the reaper: ungulate carcasses may generate an ephemeral landscape of fear for rodents ...
Animal carcasses provide an ephemeral pulse of nutrients for scavengers that utilize them. Carcass sites can increase species interactions and/or ephemeral, localized landscapes of fear for prey within the vicinity. Few studies have applied the landscape of fear to carcasses. Here we use a mass die-...
