No evidence for intercellular cooperation affecting cellular sensitivity to hyperthermia was found.
More generally, it should be stressed that while much research has sought to explain how population structure affects selection for cooperation, remarkably little attention has focussed on how cooperation affects population structure.
We performed three assays to test snail-ACL 'association': (1) regulation of each's expression by the other, (2) protein protein interaction and (3) functional cooperation affecting the transcriptional activity of snail.
Specifically we compare two scenarios: (1) a "no selection" scenario in which cooperation does not affect individual fitness, which prevents any effect of evolutionary dynamics on demographic dynamics and (2) a "selection" scenario in which cooperation affects individual fitness, which potentially allows evolutionary dynamics to affect demographic dynamics.
Mr. Bromwich also said the company's cooperation could affect its future ability to receive permits to operate offshore.
Irene Salvatore, a former vice president in Computer Associates' accounting department, claimed in a suit filed last year that 512-lawyer Manhattan firm Kaye Scholer and partner Jane Parver failed to advise her of options besides cooperating with an inquiry into alleged accounting fraud at the company or that her cooperation might affect her employment.
Our results may stimulate research into the relation between the size and content of culture gaps that hinder cooperation and affect the performance of hospitals.
Powers et al. 53 suggest that selection for cooperation can generate linkage disequilibrium between cooperative alleles and alleles that predispose the bearer to group living, while Van Dyken and Wade 54 explore how changes in levels of cooperation can affect the scale of resource competition.
Relationships between ION structure and cooperation are examined and testable propositions are developed that high formalisation, centrality and intensity are problematic for network cooperation, while density and stability positively affect cooperation.
