Why do lynx numbers lag behind hare numbers?

Why do the crashes in lynx numbers lag behind the crashes in hare numbers? Answer: It takes a while for the lynx to suffer the effects of a reduced food supply. They may find other food sources, but, if not adequate, they will begin to die. Their birthrate will also decline sometime after their food source declines.

Why do lynx numbers smaller than hare numbers?

When hares become scarce, lynx numbers also decline. Their lack of fat reserves makes them less able to live through starvation and cold temperatures.

Why does the hare and lynx population number fluctuate?

When the plants they feed on decline, so too does the hare numbers as they face starvation. The Lynx populations also fluctuate with the Hare population declines, as they are forced to hunt less nutritious species such as mice and carrion. This means that may face starvation or reduced reproduction.

What is the relationship between the lynx and the hare?

The lynx and hare populations have a predator-prey relationship. Disease, food supply and other predators are variables in this complex relationship. The flux in this cyclic relationship is what allows for the ecosystem dynamic to work.

What are the limiting factors for the snowshoe hare and the lynx?

Snowshoe hares across the boreal forest are a key food for many predators and their cycles have been the subject of large-scale field experiments that have pinpointed predation as the key limiting factor causing these fluctuations. Predators kill hares directly and indirectly stress them by unsuccessful pursuits.

Why is the lynx called a specialist?

Why is the lynx called a specialist? They eat many types of food. They only eat one type of food. These animals are called generalists.

What happens when the lynx population rises?

The Lynx population also increases because there is more food for them to eat. What does the increase in the lynx population lead to? It leads to a decrease in the hare population because the lynxes were eating the hares. What other factors could have decreased the hare population?

What would happen to the hare population of the lynx become extinct?

Which statement about snowshoe hare and lynx populations in boreal Canada is false quizlet?

Which statement about snowshoe hare and lynx populations in boreal Canada is false? Lynx are not the only important predator of snowshoe hares.

How do snowshoe hares change when predators are abundant?

Most parasites and parasitoids spend their entire lives consuming a single individual, whereas herbivores and predators usually eat at least several different individuals. How do snowshoe hares change when predators are abundant? A. They evolve aposematic coloration.

How are snowshoe hares affected by climate change?

Climate factors, such as decreased snow duration and increased temperatures, are known to have increased camouflage mismatch (i.e. an inability to match seasonal coat color molts with the surrounding landscape, see photo), in snowshoe hares leaving them more vulnerable to predation.
