Sometimes it’s hard to tell what’s a vulnerable population from one that is just at the fringe of its physio-behavioral range. A common bat in the Houston area is the Mexican Freetailed. Looking at its documented range makes me think it isn’t well suited for freezes either directly or by the nature of what it predates or pollinates. If this species (or any vulnerable population) were to be propped up in Houston, what would be the effects on other ecosystem participants that may depend on periodic removal of the first species? https://en.wikipedia.org/wiki/Mexican_free-tailed_bat https://en.wikipedia.org/wiki/Mexican_free-tailed_bat
