Sentences with phrase «low prey densities»

Amur tigers have the largest home range of any tiger subspecies because they have to search over large areas to find food due to low prey densities.

But the research development of the techniques to count prey and tigers and doing studies in different sites across India with high and low prey densities show very clearly that the number of tigers is linked to the number of prey in a very, very strong relationship.

Not exact matches

Mountain lions occur at far lower densities than deer, and so any loss of their prey can have disporportionate impacts on their reproductive rates and overall abundance.»

Territoriality also dampens growth of predator populations, contributing to the lagged response of predator to prey population growth and allowing fluctuating prey populations time to recover from low density in systems with linked predator and prey population dynamics3, 6,7,8.

We argue that the behavioural capacity of feral cats to undertake long - distance excursions to exploit transient hunting opportunities results in significantly higher total predator pressure on prey, and helps to explain how low - density cat populations could have large impacts on small - mammal abundance at landscape scales.

A closer look reveals that they conform to biological laws including predator - prey dynamics (seal Pokémon can be found in low numbers amongst high densities of fish Pokémon) and even something known as niche theory; the idea that all plants and animals occupy a pretty specific set of environmental conditions (you won't find a sun - loving grass - type Pokémon in a dark cave).
