prey species造句

Like many introduced species, American mink can slash their way through the ecosystem, as they have no native predators, and their prey species haven't evolved to avoid them.

The researchers say this could be due to a northward range shift in the mammal, a scarcity of the beast, or an increasing human preference for other prey species.

In the first week, the team found a piece of tiger fur caught on a fence, and droppings and sightings of the main prey species - wild boar and sika deer - as well as snares and traps left by poachers.
