Other biotic factors that have been shown to influence AM fungi are root predators [ 28], plant parasites [ 29], and herbivores [ 30].
On some of the most elite college campuses in America, the problem of sexual violence against women is so acute that the U.S. Department of Education has had to issue extreme regulations to force institutions of higher education to root out predators and criminals from campus communities.
Among this series's many rare feats is that it often encourages you to root for the predator rather than the prey: fitting at a time when the planet itself seems as vulnerable as a newly hatched penguin.
When it comes to managing wildlife though, I root for the predator.
My son always roots for the predator.
There is the usual difficulty in knowing whether to root for the predators and the prey — everybody's got to eat, and everybody wants to live — and sequences in which wolves hunt bison and killer whales go for seal play out at what seemed to me excruciating length.
We didn't have much trouble getting into step: I suspect that 90% of viewers were rooting for the predators, and, after all, what have the impalas or wildebeest ever done for us?
It is clearly a dangerous behavior for worms, and seems counterintuitive given that irrespective of human bait collectors - terrestrial earthworm predators rooting through soil could produce ground vibrations, and therefore the opposite response (moving deeper into the soil) might be predicted.
In this work, a prey-predator model with square root response function under a state-dependent impulse is proposed.
The proportion of prey missing was arcsine square root transformed and analyzed by factorial ANOVA with predator, prey, and the interaction as fixed effects.
On the basis of the predator-prey model (1.1) with square root functional responses, we formulate a new model (1.2) with state impulsive control strategy.
