Be it the horseshoe crab whose eggs feed millions of migrating shorebirds; bats that suppress insect outbreaks in a warming climate; or corals that shelter and feed oceans of fish, while protecting our shorelines from storms — there are no technological alternatives, nor is there enough money on the planet, to replace these free services.

Insect outbreaks such as this represent an important mechanism by which climate change may undermine the ability of northern forests to take up and store atmospheric carbon, and such impacts should be accounted for in large - scale modelling analyses.

Insect outbreaks are associated with a rapid population increase of a single insect species, so the high diversity of mining damage seen in the Mexican Hat fossils makes the possibility of an outbreak improbable.

A disturbance event such as fire or flood or an insect outbreak sweeps through a given ecosystem, and when the flames have died down and new shoots appear, they're not necessarily the same species as populated the landscape before.

The standard management response to natural disturbances such as windstorms and insect outbreaks is salvage logging, or the removal of affected trees; however, this may have detrimental effects on species of conservation concern.

Ultimately, in forests not otherwise limited by energy or nutrients variability in moisture availability with natural and climate oscillations may drive establishment success between years (League and Veblen 2006), with indirect disturbance effects (e.g., fires, landslides, insect outbreaks, and pathogen attacks) greatly affecting long - term recruitment success (Clark et al. 2016).

This becomes especially important once you get to the juvenile growth phase of those trees, keep in mind that what was a 1200 - year old mighty tree at sampling in 1980 or whenever, was much thinner a 1000 years earlier, and therefore much liklier to be influenced by competition, insect outbreaks, avalanches, rock movements, fire or other disturbances during its youth.
