What's the definition of 'natural prey' and 'natural predator'?
2022年4月3日 · The only natural predator of leopard seals is the killer whale. The Wikipedia article on Leopard says. The leopard is primarily threatened by habitat fragmentation and conversion of forest to agriculturally used land, which lead to a declining natural prey base, human–wildlife conflict with livestock herders and high leopard mortality rates.
Are there predators evolved to eat puffer fish?
2013年2月24日 · $\begingroup$ thanks @DVK I should add that its also possible that Fugu could be a small enough player in its environment so that no predator has selectively pursued it. It depends on the likeliyhood that an animal can be susceptible to the toxin and how many sources of food there are for those predators in the environment. $\endgroup$
Premise of life cycle synchronization between predator and prey
Imagine a predator of the cicada which takes several years to reach maturity(say, five). The population of this predator is distributed evenly across all the different stages of its life cycle, at least at first. One year there is a cicada eruption and all the members of this predator species are incredibly well-fed for a month or two.
Is it possible for a prey to become its main predator's predator?
Also it should be noted as you move from prey to predator, there is less energy to be had. This is why we often do not have a predator of a predator species. There simply isn't enough food at that level of a predator to support another predator above it. That said, I am assuming you are thinking of an alien ecosystem.

2016年6月26日 · I disagree with GForce's explanation; the meaning is not that growth of prey populations causes instability in predator species. The sentence is merely saying that without predation, prey population growth is more likely to be at a …
genetics - The Perfect Predator? - Biology Stack Exchange
2021年1月22日 · What would it mean to be "perfect" at being a predator? Would it mean: Fastest possible at chasing its prey? But it just needs to be faster than the prey, if it even bothers to chase its prey. Sea anemones are predators. Most exactly adapted to hunting a specific prey? Are anteaters a near-perfect predator? Deadliest possible poison?
What is the difference between a predator and a parasite?
2016年5月7日 · The parasite and that tiny component then develop what is fundamentally a predator-prey relationship. Whether the host is significantly affected or not depends upon the role of the component in the host’s overall health, and the size of the infection or wound. Exactly the same could be said about an attack by a predator on its prey.
References concerning the relative population sizes of predator …
There, the density relationships between "predator" (parasitoid) and "prey" can be very different, especially at certain points in time or at certain lifestages. For instance, in insects it is not uncommon for one "prey" (host) to give rise to a large number of newly hatched "predators".
Can predator-prey relationship be an example of negative feedback?
The predators would then choose to eat the prey (I suppose this could be the controller) and then act as the effector by eating the prey (and thus, reducing the prey population). Though I'm a little iffy on this since you'd have the predator acting as both the sensor, controller and the effector.
Examples of prey predator interactions where density of predator …
A low predator density is not synonym with "threat of extinction". Of course large predators are more prone to extinction because of lower numbers, but they usually exist in lower densities than prey (look, for instance, Lotka-Volterra equations and …
