Natural Variation in Human Clocks [PDF]

open access: yes, 2017
Our own species has a diurnal activity pattern and an average circadian period of 24.2 hours. Exact determination of circadian period requires expensive and intrusive protocols, and investigators are therefore using chronotype questionnaires as a proxy ...

Natural Variation and Neuromechanical Systems [PDF]

open access: yes, 2009
Natural variation plays an important but subtle and often ignored role in neuromechanical systems. This is especially important when designing for living or hybrid systems \ud which involve a biological or self-assembling component.

Natural variation of model mutant phenotypes in Ciona intestinalis [PDF]

open access: yes, 2008
The study of ascidians (Chordata, Tunicata) has made a considerable contribution to our understanding of the origin and evolution of basal chordates. To provide further information to support forward genetics in Ciona intestinalis, we used a combination ...

Variations in natural resistance to tuberculosis [PDF]

open access: yesJournal of Hygiene, 1960
1. ‘Resistant’ and ‘susceptible’ species of animals appear to be more or less equally susceptible to lung infection with equal doses of tubercle bacilli. Therefore it is pertinent to ask whether recognized natural differences in species resistant are in fact significant. For example, in terms of death rates (i.e. of overall resistance) the C57 mouse is

The Natural Variation of a Neural Code

open access: yesPLoS ONE, 2012
The way information is represented by sequences of action potentials of spiking neurons is determined by the input each neuron receives, but also by its biophysics, and the specifics of the circuit in which it is embedded. Even the "code" of identified neurons can vary considerably from individual to individual. Here we compared the neural codes of the

Natural enemies drive geographic variation in plant defenses [PDF]

open access: yes, 2012
Plants defend themselves against attack by natural enemies, and these defenses vary widely across populations. However, whether communities of natural enemies are a sufficiently potent force to maintain polymorphisms in defensive traits is largely ...

Characterization of the natural variation in Arabidopsis thaliana metabolome by the analysis of metabolic [PDF]

open access: yes, 2011
Metabolite fingerprinting is widely used to unravel the chemical characteristics of biological samples. Multivariate data analysis and other statistical tools are subsequently used to analyze and visualize the plasticity of the metabolome and/or the ...
