One classical thermal escape mechanism is Jeans escape, [1] named after British astronomer Sir James Jeans, who first described this process of atmospheric loss. [2] In a quantity of gas, the average velocity of any one molecule is measured by the gas's temperature, but the velocities of individual molecules change as they collide with one another, gaining and losing kinetic energy.
Escape response in Antarctic krill.. Escape response, escape reaction, or escape behavior is a mechanism by which animals avoid potential predation.It consists of a rapid sequence of movements, or lack of movement, that position the animal in such a way that allows it to hide, freeze, or flee from the supposed predator.
Anti-predator adaptations are mechanisms developed through evolution that assist prey organisms in their constant struggle against predators. Throughout the animal kingdom, adaptations have evolved for every stage of this struggle, namely by avoiding detection, warding off attack, fighting back, or escaping when caught.
Non-giant escape is often used after an initial giant interneuron-mediated tail flip. Compared to MG escape, the potentials produced in the MoG neurons by non-giant circuitry have lower amplitudes and longer durations while the recordings in the FF muscles are more erratic and have smaller amplitudes since they receive smaller EPSPs from the MoGs.
Escape and radiate coevolution produces much more biological variation than other evolutionary mechanisms. For instance, cospeciation is important for diversity amongst species that share a symbiotic relationship, however this does not create nearly as much diversity in comparison to reciprocal evolutionary change due to natural selection.

Scientists found that the EEI is the most important metric related to climate change. It is the net result of all the processes and feedbacks in play in the climate system. [1] Knowing how much extra energy affects weather systems and rainfall is vital to understand the increasing weather extremes. [1]
Positive climate change feedbacks amplify changes in the climate system, and can lead to destabilizing effects for the climate. [2] An increase in temperature from greenhouse gases leading to increased water vapor (which is itself a greenhouse gas) causing further warming is a positive feedback, but not a runaway effect, on Earth.

This process can occur in a number of different ways of both a genetic and an environmental nature. [1] Such mechanisms include homologous recombination, and manipulation and resistance of the host's immune responses. [2] Different antigens are able to escape through a variety of mechanisms.
