The sympathetic nervous system (SNS). it is predominant in dangerous situations.
It provokes the appropriate actions for rapid response such as: increased heart rate, dilated bronchi to promote the entry and exit of gases, increased sweating, decreased intestinal peristalsis to decrease the energy invested in digestion, vasoconstriction of the arteries, dilation of the pupils so that more light enters, etc.
For this reason axons quickly send a response to all these organs through the sympathetic nervous system.
Introduction of new species in an ecosystem may disrupt the existing ecological balance.
For instance, let us assume that the newly introduced specie is not a prey to anyone and the ecosystem will provide the optimal condition that it needs, then the said specie is very like to adopt, grow and reproduce in the said environment.
This will threaten the species of rabbit as their population is expected to decline. A decline in their population may also affect other species and allow them to flourish, like for example, the plants that these rabbits feed on.

I found this in a science text. I hope it is useful.
Explanation:
"En muchas flores, los pistilos y los estambres alcanzan la madurez en momentos diferentes. ... Al madurar en momentos diferentes, la flor se ve obligada a fecundar o ser fecundada por otra. Esta es la forma que tiene la naturaleza de evitar la endogamia y asegurar que el resultado sea una descendencia vigorosa."

"In many flowers, the pistils and stamens reach maturity at different times. ... By maturing at different times, the flower is forced to fertilize, or be fertilized by another. This is nature's way of preventing inbreeding and ensuring that the result will be vigorous progeny."
I'm not a Spanish speaker, so if something sounds strange here, don't blame me.
Sorry if I couldn't help.
