Phenotypic heterogeneity is a selected trait in natural yeast populations subject to environmental stress
Populations of genetically uniform microorganisms exhibit phenotypic heterogeneity, where individual cells have varying phenotypes. Such phenotypes include fitness-determining traits. Phenotypic heterogeneity has been linked to increased population-level fitness in laboratory studies, but its adaptive significance for wild microorganisms in the natural environment is unknown. Here, we addressed...
متن کاملSocial personality trait and fitness.
Several recent studies have explored various aspects of animal personality and their ecological consequences. However, the processes responsible for the maintenance of personality variability within a population are still largely unknown. We have recently demonstrated that social personality traits exist in the common lizard (Lacerta vivipara) and that the variation in sociability provides an e...
متن کاملHydrodynamic Simulation of Oil Blowout and Response Action to Evaluate Environmental Consequences on Prawns
A scenario-specific modeling of oil blowout from the Khark island pipelines in the Persian Gulf has been carried out to evaluate the environmental impact of oil spill on the local coast, seabed and prawns. Also, various scenarios for response actions have been considered. The analyses have been performed by SINTEF Oil Spill Contingency and Response (OSCAR), a 3-dimensional model system. At the ...
متن کاملMycobacterium tuberculosis invasion of macrophages: linking bacterial gene expression to environmental cues.
A central feature of Mycobacterium tuberculosis (Mtb) pathogenesis is the ability of Mtb to survive within macrophages (MØ). Despite its critical importance, our appreciation of the interplay between these two cells remains superficial. We employed microarrays to conduct a stepwise dissection of Mtb-MØ interaction during the invasion of resting bone marrow MØ. Contrary to many bacterial pathoge...
متن کاملFloral pathway integrator gene expression mediates gradual transmission of environmental and endogenous cues to flowering time
The appropriate timing of flowering is crucial for the reproductive success of plants. Hence, intricate genetic networks integrate various environmental and endogenous cues such as temperature or hormonal statues. These signals integrate into a network of floral pathway integrator genes. At a quantitative level, it is currently unclear how the impact of genetic variation in signaling pathways o...
