Sentences with phrase «in prey density»

Contrary to previous paradigms, we demonstrate that blue whales are not indiscriminate grazers but instead switch foraging strategies in response to variation in prey density and depth to maximize energetic efficiency.

Not exact matches

What's more, the ship where the researchers were working could monitor the density of prey in the water underneath it, so Cade could figure out what the whales were eating.

That a simple change in the concentration of food could lead to such unusual behavior speaks to how prey density can drive the evolution of new hunting strategies, Cade suggested.

And the whales are beginning to feed at various depths as well as along the sea floor, a shift that may have to do with changes in the population densities of their prey.

But increasing human density, climate change, or other factors may have resulted in scarcities in these prey, such that wolves began scavenging to survive.

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.

In addition, camera traps recorded whether the animals» prey sources were more likely encountered in the higher housing densities or in more wild, public land areas like national forestlandIn addition, camera traps recorded whether the animals» prey sources were more likely encountered in the higher housing densities or in more wild, public land areas like national forestlandin the higher housing densities or in more wild, public land areas like national forestlandin more wild, public land areas like national forestlands.

SWFSC scientists are also using fisheries acoustic technologies to measure the distribution and density of prey being exploited by foraging mysticete whales involved in behavioral studies.

We wanted to pass along a recent manuscript on optimal foraging in blue whales as a function of oxygen use and prey density.

«They are a significant predator of small animals, and can survive as almost solitary animals when the prey is scarce, while thriving in high density when the prey is abundant,» Beck told Life's Little Mysteries.

They note that further extended studies are needed, especially in large urbanized areas with varied habitat types, cat densities and prey availability.

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.

The higher cat densities observed near some developed areas may be spillover from overcrowded conditions associated with TNR colonies and unsterilized pets, which may affect native prey populations in areas immediately adjacent to colonies.

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).
