The span of control of the average manager in an organization determines the width of the organization as seen when viewing the organizational chart. Fewer reports to the average manager will result in a taller organizational chart, with more management positions relative to the number of individual contributors.
Philippine crocodile. This freshwater species is on the verge of extinction due to habitat destruction, hunting and dynamite fishing. Only a handful of these animals survive in the wild presently and aggressive conservation efforts are on to protect them from going extinct.
In its latest four-year endangered species assessment, the IUCN reports that the world won't meet a goal of reversing the extinction trend toward species depletion by 2010 [5]. What's clear is that many thousands of species are at risk of disappearing forever in the coming decades. No group of animals has a higher rate of endangerment than amphibians. Scientists estimate that a third or more of all the roughly 6,300 known species of amphibians are at risk of extinction [6]. The current amphibian extinction rate may range from 25,039 to 45,474 times the background extinction rate [7].
