Predator satiation (less commonly called predator saturation) is an antipredator adaptation in which prey occur at high population densities, reducing the probability of an individual organism being eaten.
When predators are flooded with potential prey, they can consume only a certain amount, so by occurring at high densities prey benefit from a safety in numbers effect. This strategy has evolved in a diverse range of prey, including notably many species of plants, insects, and fish. Predator satiation can be considered a type of refuge from predators.
As available food increases, a predator has more chances of survival, growth, and reproduction. However, as food supply begins to overwhelm the predator's ability to consume and process it, consumption levels off. This pattern is evident in the functional response of type II. There are also limits to population growth (numerical response), dependent on the generation time of the predator species.
This phenomenon is particularly conspicuous when it takes the form of masting, the production of large numbers of seeds by a population of plants.

Periodical Cicadas Overrun the Forest | Planet Earth | BBC Earth
The biggest insect emergence on the planet is underway - after an absence of 17 years the next batch of Periodical Cicadas will grace the Forest for just a mere few days. For the Turtle and other Forest inhabitants this will be one very rare but ultimately satisfying banquet.

PREDATOR SATIATION
published: 08 Dec 2008
When Trees Go Nuts
Every once in a while, all the oaks or spruces or other plants in a region suddenly produce a tremendous bounty of seeds – up to 100 times more than usual. But why do they do it, and how do they all manage to sync up?
LEARN MORE
**************
To learn more about this topic, start your googling with these keywords:
- Mast Year: A year in which all the plants of a particular species in a region ramp up their seed production.
- Predator Satiation Hypothesis: The hypothesis that mast seeding is a strategy plants use for controlling the population of squirrels and other seed-eating animals.

What is a PERIODICAL CICADA?
Curiosity starts with a thought.

What is mast, a mast year, and why do they occur? (featuring Red and White Oak identification)
Ecologists, hunters and game managers alike evaluate mast years and the amount of mast produced. But exactly what is mast? What kinds of mast are there? How do you know if trees are "masting" or if it is in fact a "mast year". Why do some species like oak trees produce a unpredictable heavy mast every 4 to 5 years? How do trees of one species synchronize and coordinate mast production simultaneously. Do trees communicate with each other? If so how? These and other questions will be answered in this video. I will also introduce how to identify White Oak, Scarlet or Red Oak and Chestnut Oak. The amount and size of oak acorns will be demonstrated. Oak tree identification is explained. The difference between hard mast and soft mast is also explained.

Every once in a while, all the oaks or spruces or other plants in a region suddenly produce a tremendous bounty of seeds – up to 100 times more than usual. But why do they do it, and how do they all manage to sync up?

Ecologists, hunters and game managers alike evaluate mast years and the amount of mast produced. But exactly what is mast? What kinds of mast are there? How do you know if trees are "masting" or if it is in fact a "mast year". Why do some species like oak trees produce a unpredictable heavy mast every 4 to 5 years? How do trees of one species synchronize and coordinate mast production simultaneously. Do trees communicate with each other? If so how? These and other questions will be answered in this video. I will also introduce how to identify White Oak, Scarlet or Red Oak and Chestnut Oak. The amount and size of oak acorns will be demonstrated. Oak tree identification is explained. The difference between hard mast and soft mast is also explained.

Given that r = 0.4 and k = 1, find R(p) - the reproduction rate. Find R #x27;(3). (Round Your answer to two decimal places) R #x27;(3) - the reproduction rate at 3 thousand organisms per hour; per one thousand additional organisms. Interpret the result: This means that the reproduction rate increases by 1.2 organisms per hour for every additional thousand organisms.

Predator satiation (less commonly called predator saturation) is an antipredator adaptation in which prey occur at high population densities, reducing the probability of an individual organism being eaten.
When predators are flooded with potential prey, they can consume only a certain amount, so by occurring at high densities prey benefit from a safety in numbers effect. This strategy has evolved in a diverse range of prey, including notably many species of plants, insects, and fish. Predator satiation can be considered a type of refuge from predators.
As available food increases, a predator has more chances of survival, growth, and reproduction. However, as food supply begins to overwhelm the predator's ability to consume and process it, consumption levels off. This pattern is evident in the functional response of type II. There are also limits to population growth (numerical response), dependent on the generation time of the predator species.
This phenomenon is particularly conspicuous when it takes the form of masting, the production of large numbers of seeds by a population of plants.
The “satiation predation” idea is complicated and suggests a kind of pact among oaks, possibly communicated via underground fungal networks, as to when to produce large amounts of fruit that will in fact attract predator chipmunks and squirrels.
The prevailing theory, known as “predator satiation,” is that the big crops of acorns in mast years are aimed at overwhelming the appetites of the animals that feed on them.
This, in turn, eases the predation pressure on caterpillars ... To survive, the insects use a predator satiation strategy. The sheer volume of bugs is so great that it overwhelms predators, reducing an individual cicada’s chance of being eaten.
Periodical cicadas emerge en masse to accomplish predator satiation," Abbott said. "There are so many that predators can get their fill, but most cicadas survive to go on and reproduce.
"Their whole survival strategy is predator satiation," said Horvath. "They're going to overwhelm the predators; it's impossible for squirrels to consume them all."
By force of numbers, cicadas “effectively satiate their predators,” LouieYang, an entomologist at the University of California Davis, told Vox a few years ago, when the famous Brood X emerged.
“They effectively satiate their predators,” LouieYang, an entomologist at the University of California Davis, told me a few years ago, when the famous Brood X emerged ... from predation,” she said.
Cicadas explained. Three facts about buzzing insects ... The two broods appear at different intervals ... “They're sort of goofy ... It's a survival tactic called "predator satiation." There are so many of them that even the hungriest predators can't eat them all.
Relatively defenseless, periodical cicadas' strength lies in their sheer numbers that satiates the appetites of the birds, foxes, racoons, turtles and other predators, John Lill, a professor of ...
The NewEmpire... He doesn't protect the people out of the goodness of his heart, so much as he does to satiate his need to be the planet's apex predator, which is an interesting parallel to Kong's very endearing desire for companionship and connection.
These cicadas’ strategy is called predator satiation, basically meaning “safety in numbers,” experts said ... Reall said it creates a feeding frenzy for predators, leaving a heavy layer of litter on sidewalks and highways that may even need shoveling.
A prevailing theory, known as the consumer satiation hypothesis, proposes a rationale ... mast seeding events appear to be losing their efficacy in satiating seed consumers ... Rafał Zwolak et al, Global patterns in the predator satiation effect of masting.
It has to do with “predator satiation,” or making sure there are enough acorns to overwhelm hungry seed predators ... Then, when a mast year finally occurs again, there aren’t enough seed predators left to fully consume the plethora of nuts.
