Populational heritability: empirical studies of evolution in metapopulations.
Using demes from experimental metapopulations of the flour beetle, Tribolium castaneum, we investigated phase 3 of Wright's shifting balance process. Using parent demes of high, intermediate, and low mean fitness, we experimentally modeled migration of varying amounts from demes of high mean fitness into demes of lower mean fitness (like phase 3) as well as the reciprocal (the opposite of phase...
متن کاملPopulational Announcement Logic (PPAL)
Populational Announcement Logic (PPAL), is a variant of the standard Public Announcement Logic (PAL) with a fuzzy semantics, where instead of specific agents we have populations and groups. The semantics and the announcement logic are defined, and an example is provided. We briefly talk about decidability and model checking. We conclude that the main advantage of PPAL over DEL and PAL is the fl...
متن کاملHeritability
What in your view is the distinguishing feature of developmental biology with respect to other natural sciences? It is the source of causality, the genome. Developmental biology differs from other sciences, physics, for example, most profoundly because of the organizing role of the primary informational content of the genome. The genomes of animals are the unique products of a billion years of ...
متن کاملIntrapersonal and populational heterogeneity of the chemokine RANTES.
BACKGROUND Current immunoassays for the chemokine RANTES (regulated on activation, normal T-cell expressed and secreted) are not tailored for specific isoforms that exist endogenously, despite the fact that variants with modified activity are known to exist. This is surprising in view of this protein's ubiquitous increased presence in many diseases and that the 2 established isoforms are trunca...
متن کاملSleep Apnea and Nocturnal Cardiac Arrhythmia: A Populational Study
Background: The mechanisms associated with the cardiovascular consequences of obstructive sleep apnea include abrupt changes in autonomic tone, which can trigger cardiac arrhythmias. The authors hypothesized that nocturnal cardiac arrhythmia occurs more frequently in patients with obstructive sleep apnea. Objective: To analyze the relationship between obstructive sleep apnea and abnormal heart ...
