Abstract Based on regional-scale studies‚ aboveground production and litter decomposition are thought to positively covary‚ because they are driven by shared biotic and climatic factors. Until now we have been unable to test whether production and decomposition are generally coupled across climatically dissimilar regions‚ because we lacked replicated data collected within a single vegetation type across multiple regions‚ obfuscating the drivers and generality of the association between production

e estimated. One should make these assumptions when executing the problem. ❏ Every litter produces six young rats‚ and three of those six rats are females. ❏ The first rat that mates births six rats on January 1. Another litter of six young rats is produced every 40 days as long as the female rat is alive. ❏ After 120 days from their birth‚ females will have their first litter of young rats. A new litter will simultaneously be produced 40 days after the first. ❏ The rat population are not exposed to any negative factors on this island
