Environmental stress, facilitation, competition, and coexistence.
The major theories regarding the combined influence of the environment and species interactions on population and community dynamics appear to conflict. Stress/ disturbance gradient models of community organization, such as the stress gradient hypothesis, emphasize a diminished role for competition in harsh environments whereas modern coexistence theory does not. Confusion about the role of spe...

متن کاملFacilitation as Attenuating of Environmental Stress among Structured Microbial Populations
There is currently an intense debate in microbial societies on whether evolution in complex communities is driven by competition or cooperation. Since Darwin, competition for scarce food resources has been considered the main ecological interaction shaping population dynamics and community structure both in vivo and in vitro. However, facilitation may be widespread across several animal and pla...
متن کاملA Diagnosis Made by 'Facilitation'.
Lambert Eaton myasthenic syndrome is a presynaptic neuromuscular junction disorder, which has unique features on electrodiagnostic testing. Here we describe a middle aged lady with symmetric, progressive, areflexic weakness in lower limbs, who had the typical electrodiagnostic findings of diffuse attenuation of motor amplitudes, and increase in these amplitudes after brief exercise of the muscl...
متن کاملGrowing Groups, Cooperation, and the Rate of Entry
We study the stability of voluntary cooperation in response to varying group growth rates. Using a laboratory public-good game, we construct a situation where increasing group size yields potential efficiency gains, but only with sustained cooperation. We then study the effect of exogenously varying growth rates on cooperation. Slow growth yields higher cooperation rates and welfare than fast g...
