Personally I feel there is nothing to worry about, most if not all of these species are well adapted to these periodic "disasters" and will recover fairly quickly.

Also, keep in mind that a species is not a a "fixed" entity, but rather a fluid population with various types of gene flows. Species therefore are fluid by nature, always in a state of flux and never static (unless you are a strict creationist and "believe" that God made all creatures as they are, I fortunately do not hold that archaic understanding). Species, or more precisely, gene sharing populations shift, diminish, vanish, transform and move on or just come to dead ends, think non-avian therapods. To better understand constant flux and change consider the genus of Doryline ants, Neivamyrmex. There are over 120 recognized "species" and paleophylogenetically they all have a common ancestor or population of ants from which the current diversity arose. Now all these thousands and thousands of individual colonies of various "species" of Neivamyrmex living right now where we will assume gene flow between each species population has ceased, thus establishing the individual species, have always been unbroken mass numbers of ants per colony generation after generation year after year, century after century, millennium after millennium, epoch after epoch...unbroken fissioning clusters of ants and all that meandering in space and time going back millions of years populations separated and separated, filled different niches, different geographies till we have the current snap shot of Neivamyrmex, which is still under change and fluid movement. So consider the Neivamyrmex opacithorax colony you find in Tennessee has literally been a "unit" a colony of mass individuals unbroken for millions and millions of years, just now you are see a "snapshot" of where it is, yet if it is successful and keeps fissioning and dividing and budding off in time divergences may occur, populations stop sharing genes and pow!! You have two or more separate species!!. See species like this and understand that though we are seeing many "dead ends" or extinctions now, 99.9% of all species have run into that wall!
